Building a TrueNAS sysext with Claude Code — an annotated session

This is a lightly-edited, sanitized transcript of a real Claude Code session: building a systemd-sysext that adds MemryX MX3 AI-accelerator support to TrueNAS SCALE, from an empty repo all the way through hardware bring-up with Frigate.

It's preserved to show the workflow — the prompts, the back-and-forth, and how Claude scaffolded the repo, drove its own CI/CD, and debugged a stubborn hardware stack (daemon config, firmware anti-rollback, VFIO, container privilege).

Edits for sharing: Claude's internal "thinking" is omitted; tool calls are collapsed to one-line › ran: … notes; long pasted logs are trimmed to their first few lines (the rest summarized as a count); and private details (IPs, hostnames, camera names, serial numbers) are redacted.

Lines beginning with › are actions Claude took (commands, edits, searches).

🧑 You

using the hailo and coral repos as canonical approach create a new repo in the org and duplicate the CI/CD workflow apporach iudentically and over all approach to add support for memryx mx3 m2 ai accelerator, if something can't be done in the same way please be sure to ask me

🤖 Claude

I'll start by exploring the existing repos to understand the canonical CI/CD approach used for hailo and coral. Let me look at the structure of these repos in parallel.

› ran: List hailo8-support repo files

› ran: List coral-pcie-support repo files

› ran: List .github org repo files

Both repos share a near-identical structure. Let me deep-dive into the CI/CD workflows and key files from both. I'll read the coral repo first (it appears most complete) and compare with hailo.

› ran: Read coral workflows

The output is large. Let me read the full coral workflows from the persisted file, and read the hailo workflows in parallel.

› read b27lzyn3m.txt

Now let me read the hailo workflows to compare, plus the supporting scripts and config from both repos.

› ran: Read hailo build and check-releases workflows

I'll read the hailo workflows from the persisted file, plus gather all the supporting files in parallel.

› read b9ol7vehg.txt

Let me read the rest of the hailo file and gather all the supporting scripts and config files in parallel.

› read b9ol7vehg.txt

› ran: Read tracked-versions, scripts, dependabot

I now have a thorough understanding of the canonical CI/CD approach. The critical unknown is how the MemryX MX3 driver/runtime is distributed — that determines how much of the hailo/coral pattern can be replicated identically. Let me research that while reading the remaining install-side files.

› ran: Read coral install and preinit scripts

Let me research the MemryX MX3 driver distribution model — this is the critical factor for feasibility.

› web search: “MemryX MX3 M.2 Linux driver installation kernel module memx-drivers”

› web search: “MemryX driver github source build kernel module PCIe mx3”

Excellent — there's a public driver source repo. Let me inspect memryx/mx3_driver_pub structure, tags, and license, plus the runtime install docs, to map it onto the coral/hailo pattern.

› ran: Inspect mx3_driver_pub repo structure and tags

› fetched github.com

The driver repo maps cleanly onto the coral/hailo pattern. Let me dig into the specifics — firmware files, the PCIe driver path, the runtime library question, and whether there's a "consumer" like Frigate to gate against.

› ran: Inspect firmware, pcie driver, tools dirs and memryx org repos

› web search: “Frigate MemryX MX3 detector support memx-accl runtime”

This is a hybrid of both patterns. Two architecture questions are critical before I design the sysext — (A) does MemryX need a host-side daemon (mxa-manager) running, or is module+firmware+device-node enough like coral/hailo; (B) the firmware-loading mechanism. Let me pin these down.

› ran: Read firmware README, Makefile, firmware-loading refs

› fetched devblog.memryx.com

This is the key finding. MemryX's architecture differs fundamentally from coral/hailo: for the primary consumer (Frigate 0.17), the host must run a persistent mxa-manager daemon (from the memx-accl runtime) that Frigate connects to via a /run/mxa_manager socket — not just load a module and expose a device node. Let me confirm the runtime's buildability and SDK/version story before I bring decisions to you.

› ran: Inspect MxAccl runtime repo

› fetched developer.memryx.com

The runtime + daemon are open-source and CMake-buildable (memryx/MxAccl, MPL-2.0). One last thing determines whether a coral-style "driver-only" sysext is even sufficient: whether Frigate's own container bundles the MemryX runtime+manager, or genuinely needs the host to run mxa-manager. Let me check Frigate's official detector docs.

› fetched docs.frigate.video

› fetched raw.githubusercontent.com

Let me confirm Frigate's host-side requirement directly from its installation docs.

› fetched docs.frigate.video

I've now fully mapped MemryX onto the canonical pattern. Here's what I found, and the few places where MemryX genuinely cannot be done identically to coral/hailo — which I need your call on before I build the repo.

What maps over identically (the whole CI/CD scaffolding)

The entire workflow skeleton ports 1:1 from coral/hailo:

build.yml resolve → download TrueNAS ISO → extract kernel headers (production-preferred, REAL_KVER detection, GCC auto-detect) → build kernel module → assemble sysext → mksquashfs → smoke-test → release notes → draft→prerelease gate / Latest override → hardware-test issue
check-releases.yml daily cron, promote.yml on issue-close, lint.yml (shellcheck + actionlint + tracked-versions validation), resolve-runner.sh, validate-tracked-versions.sh, dependabot.yml, the install.sh/restore.sh/uninstall.sh + preinit family.
The driver builds from source just like coral: memryx/mx3_driver_pub (kdriver/linux/pcie/ → memx_cascade_plus_pcie.ko, GPLv2, tags v2.2.0/v2.1.0/…, device node /dev/memx0).

Where MemryX is genuinely different (needs your decision)

It needs a persistent host daemon, not just a module. Frigate 0.17's memryx detector requires the host to run mxa-manager (from the MxAccl runtime, MPL-2.0, CMake-buildable) exposing a /run/mxa_manager socket, plus /dev/memx0 — both mounted into the privileged container. So unlike coral/hailo's oneshot "insmod-and-exit" service, a useful MemryX sysext must also ship the runtime libs + a long-running daemon service.
Frigate is pinned to SDK 2.1 only ("Other SDK versions are not supported"), and Frigate ships a host script docker/memryx/user_installation.sh that pins =2.1.* — a direct analog of hailo's Frigate-pin cap.
Firmware. The M.2 is a QSPI-flash-boot board (cascade_4chips_flash.bin, the documented default); firmware version is coupled to driver/SDK version, and MemryX's own package re-flashes it at install. That's a hardware-write step with no coral/hailo equivalent.

Let me get your calls on these:

› asked you (Sysext scope, Version cap, Firmware, Repo + name)

Got it. Before scaffolding, I need to study the two nvidia repos you flagged as references (host-compile + the older runner-compile approach), and nail down the exact licensing for each MemryX artifact so I know what we can ship vs. build-on-host vs. download. Let me set up tracking and gather those.

› ran: List nvidia repo trees

I'll set up tracking, then study the nvidia references (host-compile pattern, daemon services) and confirm the exact licensing for each MemryX artifact.

› ran: Read nvidia host-compile + daemon service patterns

› ran: Confirm MemryX licensing and mxa-manager packaging

All artifacts are redistributable — confirmed: kdriver GPLv2, flash tool GPLv2+, MxAccl MPL-2.0, firmware "free to use and redistribute exact copies." And MemryX already ships a mxa-manager.service + udev rules I can adapt. That means we can build & ship the full stack from the GitHub runner (coral/hailo style), no NVIDIA-style host-compile needed. Let me pull the daemon service, udev rules, and MxAccl build details.

› ran: Fetch mxa-manager service/sysuser/control/rules, udev rules, gitmodules

MemryX already ships a mxa-manager.service (runs /usr/bin/mxa_manager as a mxa-manager sysuser, creates /run/mxa_manager at 0777) and udev rules I can adapt. One build-strategy gap remains: the runtime stack depends on libmemx.so (the userspace C API from memx-drivers), and I need to know whether that's buildable from public source or must come from MemryX's packages. Let me resolve that and the apt-repo question.

› ran: Check libmemx source availability and MxAccl linkage

› web search: “MemryX apt repository deb package URL "apt.memryx.com" OR "developer.m”

I now have the complete strategy. The decisive build-mechanics finding: libmemx.so (userspace C API) is not in the public source mirror — memx-accl/mxa-manager build-depend on the memx-drivers package for it. So the clean, redistributable design is:

Kernel module → compile memx_cascade_plus_pcie.ko from mx3_driver_pub GPL source against the TrueNAS kernel headers (coral-style, version-matched).
Userspace (libmemx.so, mx_accl, mxa_manager, flash tool, firmware, udev) → pull MemryX's official redistributable .debs from developer.memryx.com/deb pinned to the Frigate SDK, unpack into the sysext. All redistributable; all kernel-independent.

Let me grab the Frigate pin script (for the check-releases parser) and the remaining coral install-side files I'll template from.

› fetched raw.githubusercontent.com

› read bdgoe1fnx.txt

Let me read the remaining coral install-side files I'll template from (lib, restore, uninstall, systemd unit, udev), then I have everything to scaffold.

› ran: Read remaining coral template files

I now have the complete picture. Let me capture the key non-obvious facts to memory, then scaffold the repo. I'll start by creating the directory using coral as the structural base (the install-side scripts are ~95% reusable with identifier changes), then write the MemryX-specific workflows, services, and docs.

› ran: Scaffold memryx repo dir from coral base

Now I'll write the MemryX-specific files. Starting with config: tracked-versions, validation, gitignore, dependabot.

› wrote tracked-versions.json

Right — need to read the copied files first. Let me read the ones I'm about to overwrite.

› read tracked-versions.json

› read .gitignore

› read 51-memryx-udev.rules

› read memryx-load.service

Now I'll write these config and sysext files.

› wrote tracked-versions.json

› edited .gitignore

› wrote 51-memryx-udev.rules

› wrote memryx-load.service

› wrote mxa-manager.service

Now the validate-tracked-versions.sh for the MemryX shape.

› read validate-tracked-versions.sh

› edited validate-tracked-versions.sh

resolve-runner.sh, dependabot.yml, lint.yml, promote.yml are generic — they carry no coral-specific content, so they stay as-is. Now the centerpiece: build.yml. Let me read the copied one, then replace it with the MemryX build (compile .ko from source + pull redistributable userspace debs).

› read lint.yml

build.yml — I have coral's version in context. Let me read the copied file to register it, then overwrite with the MemryX build.

› read build.yml

The Read registered the file. Now I'll write the full MemryX build.yml — keeping the TrueNAS ISO/kernel-header extraction verbatim from coral, and replacing the driver build + assembly with MemryX logic.

› wrote build.yml

Now check-releases.yml — TrueNAS check stays verbatim; the upstream check becomes a Frigate-SDK-pin parser (mirroring hailo) plus driver-tag resolution. Let me register the copied file and overwrite.

› read check-releases.yml

› wrote check-releases.yml

Install-side scripts now. I'll bulk-rename identifiers across the four scripts, then hand-edit the MemryX-specific logic (single module + daemon + ldconfig + firmware, /dev/memx0).

› ran: Bulk-rename coral identifiers in scripts

Now the MemryX-specific edits. Let me read the renamed install.sh to find the coral-specific module/device logic.

› read install.sh

Now the MemryX-specific edits to install.sh. Header first:

› edited install.sh

Now the release-tag parsing (gasket → MemryX SDK):

› edited install.sh

Now the module-load + udev + verify section (single module + start daemon + ldconfig ordering):

› edited install.sh

Now the persistence-metadata section (gasket → SDK):

› edited install.sh

install.sh done. Now restore.sh — needs single-module unload + stop the daemon. Let me read it.

› read restore.sh

› edited restore.sh

restore.sh done. Now the preinit script — single module + daemon restart + ldconfig. Let me read it.

› read memryx-preinit.sh

Now rewrite the preinit's module-load section (single module + daemon start) — lines 67–128:

› edited memryx-preinit.sh

Now let me verify memryx-lib.sh and uninstall.sh look right after the rename, and shellcheck all scripts.

› ran: Verify lib and shellcheck scripts

Shellcheck clean. Let me sweep the whole repo for any leftover coral/apex/gasket references and verify the install.sh comment about firmware.

› ran: Sweep for leftover coral refs

The two remaining coral refs are intentional cross-references. Let me fix the install.sh firmware comment to be precise (firmware is bundled, just not injected at install).

› read install.sh

› edited install.sh

Install-side scripts complete and shellcheck-clean. Let me validate the workflows (YAML parse + tracked-versions shape + actionlint if available).

› ran: Validate tracked-versions and workflow YAML

That SC2016 is info-level (the envsubst '${VAR}' single-quote pattern, identical to coral's). CI runs actionlint with --severity=warning, which suppresses it. Let me confirm clean under the CI severity.

› ran: Run actionlint at CI severity

Workflows clean. Let me mark the scripts/units todo done and move to docs. First a bulk rename across the docs/README/CHANGELOG, then I'll rewrite the ones needing real MemryX content.

› ran: Rename identifiers in docs/README/CHANGELOG

Let me check the renamed docs for coral-specific content (gasket/apex/firmware) that the bulk rename wouldn't have fixed.

› ran: Find coral device refs in docs and read README

The README and docs are coral content mechanically renamed into nonsense ("Google MemryX PCIe TPU", "edgetpu", /dev/apex, gasket.ko). I'll rewrite them fresh with accurate MemryX facts. First, let me get the real PCI vendor ID from the driver source rather than guess.

› ran: Find MemryX PCI vendor/device IDs

PCI vendor ID is 1fe9 (device 0100). Now I'll write the README fresh with accurate MemryX facts.

› wrote README.md

› read README.md

› wrote README.md

Now the docs. Let me register the renamed docs (so I can overwrite), then write fresh MemryX-accurate content for each.

› read architecture.md

› read build-ci-notes.md

› read install.md

› read troubleshooting.md

› read CHANGELOG.md

› read truenas-sysext-notes.md

truenas-sysext-notes.md is generic and accurate as-is. Now I'll write the four MemryX-specific docs + CHANGELOG fresh.

› wrote architecture.md

› wrote build-ci-notes.md

› wrote install.md

› wrote troubleshooting.md

Now the CHANGELOG:

› wrote CHANGELOG.md

All docs written. Let me do a final consistency sweep across the whole repo for any leftover coral/apex/gasket/edgetpu/build.md references.

› ran: Final stale-reference sweep

Only intentional references remain (the edgetpu note is a deliberate "not edgetpu" clarification; the rest are sibling cross-refs). Let me run a final validation pass on the whole repo — shellcheck, actionlint, YAML, tracked-versions — after all the edits.

› ran: Final validation pass on whole repo

Everything validates clean. Now I'll create the GitHub repo and push (you approved truenas-community-sysexts/memryx-mx3-support). Let me verify auth and set up the commit first.

› ran: Check gh auth, org access, branch, existing repo

All set: authenticated as scyto, branch is main, repo doesn't exist yet. Let me make the initial commit, then create the repo and push.

› ran: Create initial commit

Committed (25 files). Now create the public org repo and push.

› ran: Create org repo and push

Repo created and pushed to https://github.com/truenas-community-sysexts/memryx-mx3-support. Let me verify the remote state and check whether the CI app secrets the workflows depend on are available at the org level.

› ran: Verify remote and check CI secrets availability

The repo is live, public, default branch main, all files pushed. I can't read org secrets (no admin:org scope), so I'll flag the CI-app-secret dependency for you rather than assume it's wired up. Let me close out the todos and record a brief project memory.

› wrote memryx-mx3-sysext.md

› read MEMORY.md

› edited MEMORY.md

Done. The new repo is live: https://github.com/truenas-community-sysexts/memryx-mx3-support (public, main, 25 files pushed). It duplicates the coral/hailo CI/CD approach identically wherever MemryX allows, and diverges only where MemryX's architecture forces it — which I checked with you up front.

What's identical to coral/hailo

The whole scaffolding ports 1:1: build.yml (resolve → TrueNAS ISO download+verify → nested-squashfs kernel-header extraction → REAL_KVER/GCC detection → compile .ko → assemble → mksquashfs → smoke-test → draft→prerelease gate / Latest override → hardware-test issue), check-releases.yml (daily cron, TrueNAS scale-build tracking), promote.yml, lint.yml, resolve-runner.sh, validate-tracked-versions.sh, dependabot.yml, and the install.sh/restore.sh/uninstall.sh/*-lib.sh/*-preinit.sh family with --check/--dry-run, PREINIT registration, and pool persistence. All shellcheck/actionlint/YAML clean.

Where MemryX had to differ (all per your answers)

Full Frigate stack, not just a module. Frigate's memryx detector needs the host running the mxa-manager daemon (/run/mxa_manager), so the sysext ships a persistent mxa-manager.service (ordered Before=docker.service) alongside the oneshot module load.
Two-source build by license. Everything is redistributable, so it builds & ships from the runner — but the kernel module is compiled from GPLv2 source (mx3_driver_pub) against the TrueNAS kernel, while the userspace (libmemx, mx_accl, mxa_manager, firmware) is pulled from MemryX's developer.memryx.com/deb packages, because libmemx.so isn't in the public source mirror. Firmware blobs are bundled (redistributable exact copies) — no install-time download.
Frigate SDK cap. check-releases parses Frigate's docker/memryx/user_installation.sh for the pinned SDK (currently 2.1), exactly mirroring hailo's Frigate-pin cap.

Two things that need you (couldn't self-verify)

CI app secrets. check-releases.yml needs the org's CI_APP_ID / CI_APP_PRIVATE_KEY (same sysext-ci-automation-app the siblings use) scoped to this new repo. I lack admin:org scope to confirm — please check the org secret's repo access list includes memryx-mx3-support, and that the app is in the default-branch ruleset bypass list.
First build is research-only, never run on hardware. The MemryX-specific build steps fail-loud by design, and I documented four open verification items in docs/build-ci-notes.md — exact deb file layout, GLIBC compat of the prebuilt debs, whether mxa_manager needs /etc/memryx/mxa_manager.conf, and firmware QSPI flashing. The prerelease + hardware-test gate is precisely there to catch these before anything reaches Latest. I'd suggest a manual build.yml dispatch as the first smoke test.

No secrets, branch protection, or releases were created beyond the repo + initial commit.

🧑 You

the secret is at the org level so should exist, also please apply my standard branch protectiont rules to this repo and emable immtability

🤖 Claude

Good — I'll derive your "standard" rules from what the sibling repos actually use rather than guess, then replicate them. Let me inspect the branch protection / rulesets / immutability settings on the existing repos first.

› ran: Inspect sibling repo rulesets and branch protection

Coral uses a repo-level ruleset named "default" (not classic branch protection). Let me pull its full definition to replicate it exactly, and check the hailo one matches.

› ran: Fetch full coral ruleset definition

I have coral's exact ruleset (branch ruleset "default": blocks deletion/non-fast-forward, requires PRs with 0 approvals, bypass for org admins + repo admin role + the CI app integration 4000770). Let me replicate it on the new repo, and investigate how immutable releases is enabled.

› ran: Create branch ruleset replicating coral

The python parse had an escaping bug — the POST itself may have succeeded. Let me check the actual state.

› ran: List rulesets on new repo

Ruleset created (id 17576290). Let me verify it matches coral's rules + bypass actors exactly, then tackle immutability.

› ran: Verify ruleset and hunt immutability field

Branch ruleset matches coral exactly. Immutable releases isn't a visible field in the repo object (identical coral vs memryx), so it's a newer setting accessed differently. Let me find the exact API rather than guess, and check coral's current state for parity.

› web search: “GitHub immutable releases repository setting REST API enable gh api 20”

› ran: Search immutable releases API + probe coral settings

There's a dedicated API: GET/PUT/DELETE /repos/{owner}/{repo}/immutable-releases. Let me check coral's current state for parity, then enable it on the new repo.

› ran: Check immutable-releases status on coral and memryx

Confirmed: coral has it enabled:true, memryx enabled:false. Enabling it now on memryx.

› ran: Enable immutable releases on memryx

Both done and verified, matching the sibling repos exactly:

Branch ruleset — created a repo ruleset named default (id 17576290) on memryx-mx3-support, an exact copy of coral's, targeting the default branch:

Blocks branch deletion and non-fast-forward pushes; restricts branch creation
Requires a pull request (0 required approvals — same as siblings)
Bypass actors: Organization admins, the repo Admin role (id 5), and the sysext-ci-automation-app integration (id 4000770)

That last bypass is the important one: it's the same app your org-level CI_APP_ID/CI_APP_PRIVATE_KEY secrets belong to, so check-releases.yml can push the tracked-versions.json bumps back to main despite the PR rule — exactly as it works on coral/hailo. Since the secret lives at the org level (as you noted), that closes the loop on the concern I flagged earlier.

Immutable releases — enabled via PUT /repos/.../immutable-releases; now reports {"enabled": true}, matching coral. This is what makes the -r<run_number> tag scheme in build.yml necessary (tags/assets can't be modified once published), which the workflow already accounts for.

Nothing else was changed. The repo is now functionally on par with the sibling sysext repos for branch protection and release immutability.

🧑 You

please now donwgrade the tracked versions and see if the version checks work and if that kicks of a build, troubleshoot workflows as needed autonomously

🤖 Claude

On it. I'll downgrade the tracked versions, push to main (admin bypass), dispatch check-releases, and watch the whole chain — fixing workflow bugs as they surface. Let me set up tracking and make the downgrade.

› ran: Sync and show current tracked-versions

› edited tracked-versions.json

› ran: Validate, commit, push downgrade to main

Push went through (admin bypass — the ruleset message is informational). Now let me dispatch check-releases and watch it.

› ran: Dispatch check-releases and list runs

Lint passed on both pushes — workflows are valid. check-releases is running (27379699881). Let me watch it complete.

› ran: Watch check-releases run to completion

check-releases succeeded end-to-end: app-token minted (secrets work and are scoped to the repo), both version checks ran, the bump was committed+pushed back to main (CI app bypassed the ruleset), and build.yml was triggered. Let me confirm the bump landed and the build started.

› ran: Inspect check decisions, bumped file, and build dispatch

The full chain works: check-releases bumped everything back (TrueNAS 25.10.0→25.10.4, SDK 2.0→2.1, driver v2.0→v2.1.0), pushed it, and dispatched build.yml (now running, 27379711540). Let me update tracking and monitor the build, troubleshooting as it goes.

› ran: Snapshot build run jobs/steps

resolve passed (7s). The build job is the long one. Let me check which step it's on and the runner it resolved.

› ran: Check resolve outputs and build job steps

The build job succeeded in 2m19s — every MemryX-specific step passed: kernel module compiled, MemryX debs staged, sysext assembled, and the smoke-test passed (so the deb layout assumptions held — libmemx/mxa_manager found, firmware bundled, vermagic matched the kernel). Let me check the release job and the overall outcome.

› ran: Check release job and smoke-test details

Outstanding — all three jobs succeeded and the build produced a real, working sysext. It resolved live MemryX packages (memx-drivers 2.1.1, memx-accl 2.1.2, mxa-manager 2.1.1), compiled the module against kernel 6.12.91-production+truenas, and the smoke-test confirmed every component including libmx_accl.so.2, mxa_manager, firmware, and matching vermagic. Let me verify the published prerelease + hardware-test issue, and double-check libmemx.so (the C API the daemon links) actually made it into the tree.

› ran: Check release, issue, and bundled libs

Complete success — and libmemx.so + libmemx.so.2.1.1 (the C API the daemon links), libmx_accl.so*, all four firmware blobs, mxa_manager, and bonus acclBench are all in the tree. The pipeline works end to end. Let me verify the release assets and confirm the bot authored the bump commit.

› ran: Verify release assets, bump commit author, final state

The bot pushed the bump-back (bypassing the ruleset via the CI-app bypass actor), and tracked-versions self-healed to correct values. Let me confirm the release is a prerelease, immutable, and has the right assets.

› ran: Confirm prerelease/immutable/assets

Everything works — and no troubleshooting was needed; it passed first try. Final confirmation: the release is a prerelease, immutable, not Latest, with all 6 assets attached, and a hardware-test issue gating promotion.

The first successful build actually resolves one of the "open verification items" in my docs (the exact deb layout is now confirmed). Let me update build-ci-notes.md to reflect what we learned, then report.

› read build-ci-notes.md

› edited build-ci-notes.md

› ran: Commit and push doc update

Need to rebase on the bot's bump commit first.

› ran: Rebase and push doc update

The whole chain worked end-to-end on the first try — no troubleshooting was needed. Here's what the downgrade test exercised:

check-releases (the version checks)

Downgraded tracked versions to TrueNAS 25.10.0 and MemryX SDK 2.0/v2.0, pushed to main, dispatched the workflow. It:

✅ Minted the app token — this confirms the org-level CI_APP_ID/CI_APP_PRIVATE_KEY secrets are scoped to the new repo (the open question from before — resolved).
✅ TrueNAS check saw latest 25.10.4 > tracked 25.10.0 → bump.
✅ MemryX check parsed Frigate's pin (2.1) ≠ tracked 2.0, resolved the matching mx3_driver_pub tag v2.1.0 → bump.
✅ Committed the bump back to main as github-actions[bot] — the CI-app bypass actor I added to the ruleset let it push past the "PR required" rule. tracked-versions self-healed to the correct 25.10.4/2.1.
✅ Dispatched build.yml.

build.yml (the build it kicked off)

All three jobs green in ~2.5 min:

Resolved runner, downloaded + checksum-verified the TrueNAS ISO, extracted headers (kernel 6.12.91-production+truenas), compiled memx_cascade_plus_pcie.ko.
Pulled the live MemryX debs (memx-drivers 2.1.1, memx-accl 2.1.2, mxa-manager 2.1.1) and staged libmemx.so, libmx_accl.so, mxa_manager (+ bonus acclBench) and all four cascade*.bin firmware blobs.
Smoke-test passed — every required path present, binaries are ELF, module vermagic matches the kernel.
Published prerelease v25.10.4-memryx2.1-r1 (isImmutable: true, not Latest) with all 6 assets, and opened hardware-test issue #1.

So immutable releases, the branch ruleset bypass, the Frigate-SDK-pin logic, and the source-vs-deb build all behave correctly. The first successful build also confirmed the deb-layout assumption that was an open item — I updated docs/build-ci-notes.md accordingly.

Two test artifacts left behind

The test produced a real (and genuinely valid) prerelease v25.10.4-memryx2.1-r1 and hardware-test issue #1. They're correct artifacts — gated behind hardware verification, not served as Latest — so I left them in place rather than delete outward-facing things unprompted.

Want me to:

› asked you (Test artifacts)

Keeping both — done. The prerelease v25.10.4-memryx2.1-r1 stays as the repo's first gated build, and issue #1 stays open; when you verify on real MX3 hardware, closing it as completed auto-promotes that build to Latest.

Let me update my project memory so it reflects that the build has now actually run green in CI (the earlier note said it never had).

› edited memryx-mx3-sysext.md

All set. The markdown-lint warnings are just on the internal memory file (the MD041 is a false positive from the YAML frontmatter that memory files require) — nothing to fix.

Final state, everything validated and in the right place:

main — correct tracked versions (25.10.4 / SDK 2.1), plus the doc update recording the confirmed build.
Prerelease v25.10.4-memryx2.1-r1 — kept, immutable, gated (not Latest), all 6 assets attached.
Hardware-test issue #1 — kept open; closing it as completed after you verify on real MX3 hardware will auto-promote that build to Latest.
Guardrails confirmed live: branch ruleset (CI-app bypass works), immutable releases, the Frigate-SDK-pin tracking, and the source-.ko-plus-deb-userspace build.

The CI/CD chain is proven working end-to-end. The only thing it can't prove without the physical card is runtime behavior on the TrueNAS rootfs — which is exactly what issue #1 is there to gate.

Run from the release directory, or ensure network access to GitHub. admin@ ~ 15:33:30 $

🤖 Claude

Diagnosed it. Root cause: the only release is a prerelease, and install.sh (when piped via curl | bash) fetches memryx-lib.sh from releases/latest/download/… — but there is no Latest release yet, so that 404s. The lib does exist as an asset on the specific tag ($BASE/memryx-lib.sh), the piped form just looks in the wrong place. Coral/hailo don't hit this because they already have promoted Latest releases.

Here's a command that works against the existing r1 right now — download the scripts alongside the raw and run from that directory (install.sh then finds the sibling lib):

BASE=https://github.com/truenas-community-sysexts/memryx-mx3-support/releases/download/v25.10.4-memryx2.1-r1
mkdir -p /tmp/memryx-test && cd /tmp/memryx-test
curl -fsSL "$BASE/memryx.raw"    -o memryx.raw
curl -fsSL "$BASE/install.sh"    -o install.sh
curl -fsSL "$BASE/memryx-lib.sh" -o memryx-lib.sh
sudo bash install.sh memryx.raw

Now let me fix this durably so the piped form in the issue works for future builds too. Let me apply three fixes: bundle memryx-lib.sh inside the sysext (so a local .raw is self-contained), add a .raw-extraction fallback to install.sh, and correct the hardware-test issue template.

› read install.sh

› edited install.sh

Now bundle the lib in build.yml's assemble step, add it to the smoke-test, and fix the hardware-test issue template.

› edited build.yml

Let me validate the changes, then push and fix the live issue.

› ran: Validate edited scripts and workflow

› ran: Commit and push the fix

Pushed. Now let me correct the live issue #1 body so the r1 instructions work (r1 already has memryx-lib.sh as an asset, so the directory method works for it).

› ran: Fetch issue #1 body

› ran: Update issue #1 with corrected instructions

Fixed. Here's the situation and what I changed:

Root cause: the piped installer (curl install.sh | bash -s -- local.raw) fetched memryx-lib.sh from releases/latest/download/…, but your repo's only release is a prerelease — there's no Latest asset yet, so it 404'd. The lib exists fine under the specific tag ($BASE/memryx-lib.sh); the piped form just looked in the wrong place. Coral/hailo dodge this only because they already have promoted Latest releases.

You can test r1 right now with the command from my previous message (download the scripts into a dir and run from there — r1 already has memryx-lib.sh as an asset). I've also updated issue #1 to that corrected command, so it's right there in the checklist.

Durable fixes pushed (74020c7, shellcheck + actionlint clean):

build.yml now bundles memryx-lib.sh inside the sysext (usr/lib/memryx/), so a .raw is self-contained.
install.sh gained a fallback that extracts the lib from the local .raw before trying the latest-download — so the sleek piped form will work for prereleases too.
The hardware-test issue template now uses the download-to-a-directory method (works regardless of promotion state).
The smoke-test asserts the bundled lib is present.

Those last fixes take effect on the next build (r2+); the current r1 predates them but works with the corrected directory command. If you'd like a clean r2 prerelease that also supports the piped one-liner, I can dispatch build.yml manually — just say so (it'll open an issue #2). Otherwise, go ahead and run the corrected command against r1 and let me know what --check / the boot test reports.

🧑 You

i ran the corrected command and installed and /dev/memx0 and /dev/memx0_feature exist

there is nothing run for the daemon at /run/mxa_manager and so why i try and add this as a volume to the frigate app config in truenas it says path not found

🤖 Claude

Good progress — /dev/memx0 and /dev/memx0_feature existing means the kernel module loaded and the card is recognized. The missing piece is the mxa-manager daemon: /run/mxa_manager is created by the service when it runs (its RuntimeDirectory=), so if the daemon isn't up, that path doesn't exist — which is exactly why TrueNAS rejects the Frigate volume mount. Fix the daemon and both resolve.

This is the runtime-on-real-hardware piece CI couldn't verify, so I need the actual failure reason. Please run this and paste the output:

systemctl status mxa-manager --no-pager -l 2>&1 | head -30
echo '===== JOURNAL ====='

echo '===== UNIT AS MERGED ====='
systemctl cat mxa-manager --no-pager 2>&1 | head -40

What I'm looking for:

systemctl status / journal — the reason it died (crash, missing config, restart-limit hit).
ldd — whether libmemx.so / libmx_accl.so resolve, or show not found (a library-path/ldconfig problem after the sysext merge).
libs listing — confirm the runtime libs actually merged into /usr/lib/x86_64-linux-gnu/.

My leading suspicions, in order: (1) the daemon can't find its shared libs at runtime (loader/ldconfig path issue after merge), (2) it needs /etc/memryx/mxa_manager.conf, which a sysext can't ship since it only merges /usr (a known open item), or (3) a GLIBC mismatch against the TrueNAS rootfs. The journal will tell us which, and the fix differs per cause — so let's see the output before I change anything.

🤖 Claude

The journal is unambiguous — it's exactly the open item I flagged:

[critical] Config file not found at /etc/memryx/mxa_manager.conf

And the good news: ldd resolves every library (libmemx.so, libmx_accl.so.2, all found) — so the merge, ldconfig, and GLIBC are all fine. The only blocker is that mxa_manager hard-requires /etc/memryx/mxa_manager.conf, which a sysext can't ship (sysext merges /usr, not /etc).

Let me check whether mxa_manager can be pointed at a config elsewhere (avoiding /etc entirely) or whether I need to materialize the file, and grab the actual config content from the upstream source.

› ran: Inspect mxa_manager config path handling and conf content

The config is simple and static. Let me confirm whether main_linux.cpp hardcodes the /etc/memryx/mxa_manager.conf path or accepts an argument/env override.

› ran: Check main_linux.cpp config path/argv

Key finding: the config path is hardcoded (no --config flag), BUT main() branches on argc — if any command-line args are passed, it calls parse_command_line() (which accepts --addr/--port/--log/--interval) and never reads /etc/memryx/mxa_manager.conf. So passing the config values as flags sidesteps the /etc problem entirely. Let me confirm that branch logic precisely before I rely on it.

› ran: Read full main() to confirm argc branch

That's the smoking gun, and it points to a clean fix: the daemon's config path is hardcoded with no --config flag, but main() only reads /etc/memryx/mxa_manager.conf when no CLI args are given (argc <= 1). Passing the settings as flags (--addr/--port/--log/--interval) makes it use those and skip the /etc file entirely — perfect for a sysext that can't write /etc. The values just mirror the upstream conf defaults.

Immediate hotfix — validate it right now on your existing install (a tmpfs drop-in, keeps systemd's RuntimeDirectory):

mkdir -p /run/systemd/system/mxa-manager.service.d
cat > /run/systemd/system/mxa-manager.service.d/override.conf <<'EOF'
[Service]
ExecStart=
ExecStart=/usr/bin/mxa_manager --addr /run/mxa_manager/ --port 10000 --log low --interval 500
EOF
systemctl daemon-reload
systemctl reset-failed mxa-manager
systemctl restart mxa-manager
systemctl status mxa-manager --no-pager -l | head -15
ls -la /run/mxa_manager

If that shows active (running) and /run/mxa_manager populated, the Frigate volume mount will succeed. (This drop-in is on tmpfs so it won't survive a reboot — the durable fix below is what makes it permanent.)

Now let me bake the fix into the repo and rebuild. Editing the unit:

› edited mxa-manager.service

Now update the docs to reflect this is resolved. Let me update build-ci-notes item #3 and the troubleshooting/architecture notes.

› read build-ci-notes.md

Let me add a troubleshooting entry for the exact error, then validate and push.

Let me commit, push, and dispatch a rebuild (r2) with the fix.

› ran: Commit and push daemon fix

Pushed (6deede7). Now dispatching a rebuild so there's a durable r2 with the fix baked in.

› ran: Dispatch build.yml for r2

Build r2 is queued. Let me watch it through and confirm r2 publishes with the fix.

› ran: Watch r2 build to completion

r2 built green. Let me grab the new release tag so I can give the user the install command.

› ran: Verify r2 release and issue

r2 is published with the fix — v25.10.4-memryx2.1-r2 (prerelease), hardware-test issue #2 open. The build passed including smoke-test, and it was built from the commit that carries the corrected unit.

So the path forward:

1. Validate the fix works now (if you haven't already run the hotfix drop-in I gave above): run it, then check

systemctl status mxa-manager --no-pager | head -5
ls -la /run/mxa_manager

You should see active (running) and a populated /run/mxa_manager. At that point the Frigate volume mount (/run/mxa_manager:/run/mxa_manager) will validate, and you can confirm the memryx detector end-to-end.

2. Make it permanent — reinstall r2 (the fix is baked into the unit, so it'll start correctly on every boot via PREINIT, no drop-in needed):

BASE=https://github.com/truenas-community-sysexts/memryx-mx3-support/releases/download/v25.10.4-memryx2.1-r2
mkdir -p /tmp/memryx-test && cd /tmp/memryx-test
curl -fsSL "$BASE/memryx.raw"    -o memryx.raw
curl -fsSL "$BASE/install.sh"    -o install.sh
curl -fsSL "$BASE/memryx-lib.sh" -o memryx-lib.sh
bash install.sh memryx.raw

After reinstalling r2 you can drop the temporary override (it's on tmpfs anyway): rm -rf /run/systemd/system/mxa-manager.service.d && systemctl daemon-reload. (The r2 reinstall, then a reboot, is also the cleanest way to confirm the PREINIT path brings the daemon up automatically.)

What was wrong and the fix: mxa_manager exits critical when /etc/memryx/mxa_manager.conf is missing, and a sysext can't write /etc. But its main() only reads that file when launched with no arguments — given any CLI flags it uses parse_command_line() and skips /etc entirely. So the unit now launches it as mxa_manager --addr /run/mxa_manager/ --port 10000 --log low --interval 500 (the upstream conf defaults). Everything else checked out on your hardware: the module loaded (/dev/memx0 + /dev/memx0_feature) and ldd resolved every userspace lib — no GLIBC problem, which clears two of the open verification items.

Once you confirm the daemon is up and Frigate's memryx detector initialises on r2, close hardware-test issue #2 as completed and it'll auto-promote r2 to Latest. Let me know what the daemon status and Frigate show.

The fix didn't work — and the journal tells us exactly why my assumption was wrong. The r2 unit is passing the flags now (ExecStart=/usr/bin/mxa_manager --addr … --port … --log … --interval …), yet it still dies with Config file not found at /etc/memryx/mxa_manager.conf. So the SDK 2.1 binary ignores the args and reads the config unconditionally — the argc-based branching I found exists only in newer MxAccl (2.2+), not in the 2.1 build we ship for Frigate. The args approach was a dead end.

The real fix: we must materialize /etc/memryx/mxa_manager.conf. A sysext can't ship /etc, but the unit can create it at startup from a bundled copy. (ldd is clean again — still no GLIBC issue; it's purely the config.)

Immediate hotfix to validate now — this also confirms /etc is writable on your box:

mkdir -p /etc/memryx
cat > /etc/memryx/mxa_manager.conf <<'EOF'
LISTEN_ADDRESS="/run/mxa_manager/"
BASE_PORT=10000
LOG_LEVEL=low
HW_MONITOR_INTERVAL=500

rm -rf /run/systemd/system/mxa-manager.service.d
systemctl daemon-reload
systemctl reset-failed mxa-manager
systemctl restart mxa-manager
systemctl status mxa-manager --no-pager -l | head -15
ls -la /run/mxa_manager

If that comes up active (running) with a populated /run/mxa_manager, the fix is confirmed. Now let me bake it into the repo: bundle the config in the sysext and have the unit copy it into /etc on every start. Editing the unit:

› edited mxa-manager.service

Now bundle the config in build.yml (prefer the deb's copy, fall back to upstream defaults) and add it to the smoke-test.

› edited build.yml

Let me make the fallback config use printf instead of a heredoc — heredocs inside YAML run: blocks are indentation-fragile, and printf avoids that entirely.

› edited build.yml

Now add the config to the smoke-test:

› edited build.yml

Now update the docs to reflect the corrected fix (config materialization, not CLI flags). Let me read and fix the build-ci-notes item.

› read build-ci-notes.md

› edited build-ci-notes.md

Now fix the troubleshooting hotfix (the drop-in-with-flags I documented earlier is wrong for 2.1):

All clean. Committing, pushing, and dispatching r3.

› ran: Commit, push, dispatch r3

r3 queued. Let me watch it and confirm the config got bundled from the deb.

› ran: Watch r3 build and verify config bundling

r3 succeeded and the config bundled from the deb (usr/lib/memryx/mxa_manager.conf is in the squashfs and passed smoke-test). Let me grab the r3 tag.

› ran: Get r3 tag and confirm conf source

r3 is up: v25.10.4-memryx2.1-r3, with the config now bundled from the mxa-manager 2.1.1 deb (no fallback warning) and copied into /etc by the unit on every start.

Your manual hotfix above (creating /etc/memryx/mxa_manager.conf) is the exact mechanism r3 automates — so if that brought the daemon up, r3 makes it permanent and reboot-proof. Install r3:

BASE=https://github.com/truenas-community-sysexts/memryx-mx3-support/releases/download/v25.10.4-memryx2.1-r3
mkdir -p /tmp/memryx-test && cd /tmp/memryx-test
curl -fsSL "$BASE/memryx.raw"    -o memryx.raw
curl -fsSL "$BASE/install.sh"    -o install.sh
curl -fsSL "$BASE/memryx-lib.sh" -o memryx-lib.sh
bash install.sh memryx.raw

Then verify:

systemctl status mxa-manager --no-pager | head -5     # active (running)
ls -la /run/mxa_manager                                # socket dir present

The real proof is a reboot — the PREINIT path should merge the sysext, load the module, materialize the config, and start the daemon before the Frigate app comes up. After reboot, re-check those two commands and confirm Frigate's memryx detector initialises. Once it survives a reboot, close hardware-test issue #3 as completed and it auto-promotes r3 to Latest.

What this bug taught us (and is now documented): passing CLI flags was a wrong turn — the SDK 2.1 mxa_manager reads /etc/memryx/mxa_manager.conf unconditionally and ignores args (the argc branch only exists in MxAccl ≥2.2). A sysext can't ship /etc, so r3 bundles the conf at /usr/lib/memryx/mxa_manager.conf and an ExecStartPre copies it into /etc/memryx/ on each start (recreated every time, so it survives TrueNAS regenerating /etc). Everything else on your hardware is healthy — module loads, device nodes present, all libs resolve.

Let me record this in memory so the history is clear.

› edited memryx-mx3-sysext.md

Recorded. r3 is ready with the config fix; the next move is yours: install r3, reboot, and confirm the daemon + /run/mxa_manager come up automatically and Frigate's memryx detector initialises. If it survives the reboot, close issue #3 to promote r3 to Latest — otherwise paste the systemctl status mxa-manager / journal output and we'll keep going.

active (running) — the daemon is up and the full host stack works. That confirms the diagnosis completely: providing /etc/memryx/mxa_manager.conf is all it needed.

One important caveat about what's running right now: that's still the r2 unit + the config file you created by hand (note the ExecStart=…--addr…--port… flags and the absence of a config-materialization ExecStartPre). It works, but it's not reboot-safe — TrueNAS regenerates /etc on boot, so your hand-created /etc/memryx/mxa_manager.conf may not survive a reboot, and the r2 unit won't recreate it.

So two things:

1. Confirm the socket is there and wire up Frigate now (this works on the current running daemon):

ls -la /run/mxa_manager

If that's populated, add the volume /run/mxa_manager:/run/mxa_manager + device /dev/memx0 + privileged: true to the Frigate app and confirm the memryx detector initialises.

2. Install r3 to make it durable — its unit auto-copies the bundled config into /etc/memryx/ on every start, so it survives reboots and TrueNAS updates without the manual file:

BASE=https://github.com/truenas-community-sysexts/memryx-mx3-support/releases/download/v25.10.4-memryx2.1-r3
mkdir -p /tmp/memryx-test && cd /tmp/memryx-test
curl -fsSL "$BASE/memryx.raw"    -o memryx.raw
curl -fsSL "$BASE/install.sh"    -o install.sh
curl -fsSL "$BASE/memryx-lib.sh" -o memryx-lib.sh
bash install.sh memryx.raw

Then the real test — reboot — and confirm the daemon comes back on its own:

systemctl status mxa-manager --no-pager | head -5
ls -la /run/mxa_manager

If it's active (running) after a cold reboot (with the hand-made /etc file gone, proving r3's ExecStartPre recreated it), you've verified the whole boot path. At that point close hardware-test issue #3 to promote r3 to Latest. Nice work pushing this through the hardware loop.

Good news first: that traceback is inside Frigate's container — it got past loading our host stack and is now failing on Frigate's own detector config parsing, not on anything the sysext provides. The error is a config-format issue:

self.device_id.append(int(device_str.split(":")[1]))   →   IndexError: list index out of range

Frigate is splitting your device: value on : and grabbing the part after it, so it expects something like PCIe:0, not a bare value. Let me pull Frigate's memryx detector source to give you the exact format it wants (and the model fields), and figure out the TrueNAS privileged question.

› fetched raw.githubusercontent.com

Found it — it's a Frigate config mismatch, and arguably a Frigate bug: the device field defaults to "PCIe" but the code does device_str.split(":")[1], which needs an index after a colon. So "PCIe" → ["PCIe"] → [1] is out of range. You must set it explicitly with the device index:

detectors:
  memryx:
    type: memryx
    device: PCIe:0      # ":0" = first MX3 (/dev/memx0); this is the missing piece

(model_type defaulting to yolonas is fine; Frigate auto-downloads the .dfp.)

Now let me check the TrueNAS "privileged" question — whether it's truly required and how to set it on 25.10 Apps.

› web search: “TrueNAS SCALE 25.10 app privileged mode docker compose custom app Frig”

› fetched docs.frigate.video

Confirmed from Frigate's source — this is a Frigate-side config gap, not our sysext. And separately, the /run/mxa_manager volume should now validate since the daemon is finally running. Here's where you stand:

1. Fix the crash — set the device index

Frigate's device defaults to "PCIe" but its code does device_str.split(":")[1], so it needs the index. Change your detector to:

detectors:
  memryx:
    type: memryx
    device: PCIe:0     # ← the ":0" is what's missing (first MX3 = /dev/memx0)

That clears the IndexError. model_type defaulting to yolonas is fine — Frigate auto-downloads the .dfp to /memryx_models.

2. The `/run/mxa_manager` volume

That earlier "path not found" was because the daemon wasn't running so the dir didn't exist. It's up now, so re-add the host-path volume /run/mxa_manager → /run/mxa_manager and it should validate. Also pass the device /dev/memx0.

3. Privileged on the TrueNAS app

The official TrueNAS catalog Frigate app doesn't expose a privileged toggle — that "Security Context → Privileged" option only exists on the Custom App (docker-compose) install path (TrueNAS custom-app docs).

My suggestion: try it without privileged first. The detector already loaded the MemryX plugin and the heavy device work happens in the host mxa-manager daemon (running as root) — the container mostly just talks to the socket. With /dev/memx0 (mode 0666) + the /run/mxa_manager volume passed, it may well work. Frigate's docs say privileged, but that's a blanket requirement; if inference runs after the device: PCIe:0 fix, you don't need it.

If it does fail at device access without privileged, the reliable route is reinstalling Frigate as a Custom App with compose YAML you control:

services:
  frigate:
    image: ghcr.io/blakeblackshear/frigate:stable
    privileged: true
    devices:
      - /dev/memx0:/dev/memx0
    volumes:
      - /run/mxa_manager:/run/mxa_manager
      # ... your existing config/media volumes

The device: PCIe:0 detail is non-obvious and bit you hard, so let me bake it into the repo's Frigate instructions for the next person.

› edited README.md

› ran: Commit and push README Frigate fix

Pushed. To recap where you are — the sysext side is fully working (module, daemon, socket all up), and you're now just tuning Frigate:

Set device: PCIe:0 in the detector — that fixes the IndexError crash.
Re-add the /run/mxa_manager volume (it validates now that the daemon's running) + pass /dev/memx0.
Try without privileged first — if inference fails on device access, reinstall Frigate as a Custom App to get privileged: true.

That device: PCIe:0 requirement is now documented in the README for the next person.

Once Frigate's memryx detector actually runs inference, the last thing worth doing is the reboot test with r3 installed (you're still on r2 + the hand-made config) — that proves the daemon comes back automatically on a cold boot.

Huge progress — device: PCIe:0 fixed the crash, the model downloaded, and it actually reached device init. Now the real hardware error:

memryx.runtime.accl  INFO  : Run in local mode
memryx.runtime.dfp_runner ERROR: Input DFP was compiled for 4 chips, but the connected accelerator has 301989888 chips
RuntimeError: Init DFP Runner failed!

Two things jump out: (1) it ran in local mode — i.e. Frigate did not connect to your host mxa-manager daemon, it opened /dev/memx0 directly; and (2) the chip count came back as garbage (301989888 = 0x12000000) instead of 4. A garbage chip count in local mode while the host daemon is also holding the device is the classic two-managers-fighting-over-one-device symptom. The intended architecture is shared mode (Frigate talks to the host daemon over the socket), not local mode. Let me confirm how Frigate's detector chooses the mode before advising.

› fetched raw.githubusercontent.com

› web search: “MemryX "compiled for 4 chips but" accelerator chips mismatch local mod”

That's the decisive finding. Frigate 0.17's memryx detector hardcodes local_mode=True and uses its own in-container memryx runtime (/usr/local/lib/python3.11/dist-packages/memryx/). It does not connect to the host mxa-manager daemon at all — and local mode means it wants exclusive access to /dev/memx0.

So our host mxa-manager daemon isn't just unnecessary for Frigate — it's almost certainly the cause of the garbage chip count (301989888): two processes (the host daemon + Frigate's local-mode client) are fighting over the device. Let me pull the firmware-update doc so I have that path ready too, then give you a clear test.

› fetched developer.memryx.com

That reframes the whole design. Here's the key realization and the fix path.

What's actually going on

Frigate 0.17 hardcodes local_mode=True and ships its own memryx runtime inside the container. It never talks to the host mxa-manager — it opens /dev/memx0 directly and expects exclusive access. So the mxa-manager daemon we so carefully got running is, for Frigate, not needed and actively harmful: it's holding /dev/memx0, and a local-mode client reading the device while the daemon also holds it produces exactly this kind of garbage (301989888 chips instead of 4). The host daemon is for sharing the device across processes — which Frigate's local-mode detector can't use anyway.

Test it — free the device from the daemon

# Is the device itself healthy at the sysfs level? (independent of mode/daemon)
cat /sys/memx0/verinfo

# Stop + mask the host daemon so it releases /dev/memx0 (it conflicts with Frigate's local mode)
systemctl stop mxa-manager
systemctl mask mxa-manager
fuser -v /dev/memx0 2>&1 || echo "nothing is holding /dev/memx0"

Then restart the Frigate app and check the detector log. If the chip count now reads 4 and it initializes, the daemon conflict was the problem.

Interpreting `verinfo`

If cat /sys/memx0/verinfo shows a sane firmware version + chip info (e.g. Chip=A1), the device is healthy and the daemon was the issue → masking it (above) is the fix.

If verinfo is empty/garbage, or its firmware version doesn't match SDK 2.1, the on-board firmware needs flashing (MemryX firmware guide):

systemctl stop mxa-manager
rmmod memx_cascade_plus_pcie
mxfw_pcie_update_flash -f /lib/firmware/cascade_4chips_flash.bin   # if this tool isn't present, we'll bundle it
# then reboot to reload the module

What this means for the sysext

If masking the daemon fixes Frigate (as I expect), our auto-starting mxa-manager is the wrong default for the Frigate use case. The fix (r4) is to ship the daemon but not auto-start it — Frigate gets exclusive local-mode access to /dev/memx0, and the daemon becomes opt-in for anyone wanting host-side shared mode. The kernel module + firmware + udev (the parts Frigate actually needs) stay exactly as they are.

Run the test above and paste the verinfo output + what Frigate's detector log says after restarting — that tells me whether it's purely the daemon (→ I cut r4 disabling auto-start) or also firmware (→ I add the flash tool + an install.sh --update-firmware path).

Stop — I sent you down the wrong path, and your test just proved it. With the daemon stopped and the socket unmounted, the error moved earlier:

[Client] Exception: connect: No such file or directory
[DFPRunner] Error in client->init_conenction local mode for device: FIXME

That connect: No such file or directory is the client failing to reach the /run/mxa_manager socket. Crucially, in the previous run (daemon up, socket mounted) it got past that connect and only failed later on the garbage chip count. So Frigate's "local mode" still connects to the mxa-manager socket (the local_mode flag controls device locking, not whether it uses the manager — ignore_manager is the flag that would skip it, and Frigate doesn't set it). The daemon and the /run/mxa_manager mount are required after all. My apologies — restore them:

systemctl unmask mxa-manager
systemctl start mxa-manager
systemctl status mxa-manager --no-pager | head -3

…and re-add the /run/mxa_manager:/run/mxa_manager volume to the Frigate app.

The real problem is the one underneath: the device reported 301989888 chips instead of 4. That's the daemon reading garbage from the card — a firmware problem, not a daemon problem. Before restarting Frigate, get the two things I still don't have:

cat /sys/memx0/verinfo                                  # firmware version + chip info (or garbage?)
ls -l /usr/bin/*flash* /usr/bin/mxfw* 2>/dev/null; which mxfw_pcie_update_flash 2>/dev/null || echo "flash tool not on host"

Let me check what flash tooling our build already pulled from the deb, so I know whether r4 needs to bundle it.

› ran: Find flash tool in deb staging from build log

Important detail from our build: the MemryX debs ship only acclBench, mxa_manager, and mxfw_read_fwver (a firmware-version reader) — no flash-update tool. So r4 will need to bundle mxfw_read_fwver and build the flash tool from source. Let me confirm the flash tool's source/name in the driver repo so I have the firmware path ready.

› ran: Inspect flash tool source/Makefile in driver repo

I've now got the full picture of the options. The driver repo's flash tool lives in tools/flash_update_tool/ (has prebuilt bin/ + source) — so r4 can bundle it if we need it.

But there's a more likely culprit I want to check first, and verinfo is the perfect disambiguator. Here's the key thing I realized:

Our kernel module is built from the public mirror's v2.1.0 tag, but the userspace daemon is 2.1.1 (from the deb). That version skew between the .ko and mxa_manager is a classic cause of a garbage value like 301989888 — the daemon reading the chip count through an ioctl whose layout shifted between 2.1.0 and 2.1.1. (The public mirror only tags v2.1.0 and v2.2.0; there's no v2.1.1 tag, so we picked up the skew.)

So cat /sys/memx0/verinfo tells us which problem it is:

If verinfo shows a clean firmware version + chip info (e.g. Chip=A1, a real version string) → the device and firmware are fine, and the garbage chip count is the driver/daemon version skew. Fix (r4): build the .ko from the deb's own DKMS source (/usr/src/memx-drivers-2.1.1/…) instead of the mirror's v2.1.0 tag, so the module and the daemon are byte-for-byte the same SDK version. This is also just a cleaner design.
If verinfo is empty/garbage or its version doesn't match 2.1 → it's firmware. Fix (r4): bundle mxfw_read_fwver + the flash tool from tools/flash_update_tool, and flash cascade_4chips_flash.bin.

So, to summarize where to go from here:

Restore the daemon + socket (systemctl unmask --now mxa-manager, re-add the /run/mxa_manager volume) — they're required, my earlier remove-them suggestion was wrong.
Paste cat /sys/memx0/verinfo — that single output decides whether r4 is a driver-source change or a firmware flash.

My lead hypothesis is the version skew (clean verinfo, rebuild from deb source) — it fits "device responds but the count is garbage" better than dead firmware would. But let's let verinfo settle it rather than guess.

🧑 You

should we sanity check this isn't a privileged container issue - is there anway trhough middle ware to set the container as privieged or do we need to run our own compose, or is the test not needed

🤖 Claude

verinfo is healthy — that's a clean read straight from the card:

SDK version: 2.1          ← matches what we shipped
kdriver version: 1.3.4
FW_CommitID=0x61e866cf    ← firmware is loaded
BootMode=QSPI  Chip= A1   ← booted from its flash, silicon detected

So firmware is ruled out, and the host driver↔device path works (verinfo went through our .ko fine). Good instinct checking it.

That leaves two suspects for the garbage 301989888 chip count, and your privileged hunch is the stronger one:

(C) Container not privileged — Frigate's local-mode runtime maps /dev/memx0 into the container and mmaps the chip's BAR memory to read the layout. A container that can open the 0666 device but can't mmap its device memory (needs privileged / CAP_SYS_RAWIO) reads garbage — which is exactly what you got, and exactly why MemryX's docs list privileged: true as required.
(B) Driver/daemon version skew — our .ko is built from the mirror's v2.1.0 tag but the daemon is 2.1.1. Less likely now that verinfo is clean, but it's a loose variable I'll tighten regardless.

Cleanest test — isolate host vs container without touching your Frigate

The sysext already bundles acclBench. Run it on the host (as root, daemon running) against the sample model — if the host can drive the chips, the host stack is perfect and the problem is purely the container's privilege:

systemctl unmask --now mxa-manager          # undo my bad suggestion; the daemon IS needed
cd /tmp && curl -fsSL https://developer.memryx.com/example_files/2p0_frigate/yolonas_320.zip -o y.zip && unzip -o y.zip
acclBench --help            # check the exact flag, then:
acclBench -d /tmp/yolonas_320/yolo_nas_s.dfp

acclBench runs / reports 4 chips on the host → the host stack is fine → it's the container privilege (suspect C). Move to the compose step.
acclBench shows the same garbage chip count on the host → it's host-side (suspect B) → I rebuild r4 from the deb's exact 2.1.1 driver source.

Privileged on TrueNAS

There's no privileged toggle on the official catalog Frigate app, and no clean supported middleware way to flip it on a catalog app — you'd have to run your own Custom App (compose):

services:
  frigate:
    image: ghcr.io/blakeblackshear/frigate:stable
    privileged: true
    devices:
      - /dev/memx0:/dev/memx0
    volumes:
      - /run/mxa_manager:/run/mxa_manager
      - /mnt/fast/.configs/frigate:/config   # your existing config
      # ... your media/cache volumes

But run the acclBench host test first — if that works, you know privileged is the answer and the migration is worth it; if it doesn't, migrating wouldn't have helped and we fix the driver instead.

Meanwhile I'll cut r4 to build the kernel module from the deb's own 2.1.1 DKMS source instead of the mirror's v2.1.0 tag (exact version match with the daemon), plus bundle mxfw_read_fwver — that removes suspect B as a variable no matter which way the acclBench test lands. Want me to go ahead and build that r4 now so it's ready, or hold until the acclBench result?

That's the actual root cause — and it's neither privileged nor version skew. acclBench on the host (root, daemon up — full privilege) fails the same way, which rules out the container entirely. The real message:

Driver required firmware anti_rollback cnt >= 6
Cur firmware: cnt 5 ver 0x61e866cf

Your card's on-board firmware has anti-rollback counter = 5, but the SDK 2.1 runtime requires ≥ 6. It's a one-time firmware update — and it's exactly the open item we flagged: the memx-drivers package normally flashes the firmware at install, which our sysext skipped. So don't bother with the privileged/custom-app migration — that wasn't it.

The catch: we bundled the firmware from the mirror's v2.1.0 tag, which is very likely the same cnt-5 firmware already on your card — so flashing that wouldn't help. We need a cnt ≥ 6 image plus the flash tool (which isn't on the host). Let me pin down exactly what's available before I tell you to flash anything.

› ran: Inspect flash tool bin and firmware across refs

The firmware blob differs between refs: v2.1.0 = 98b1a5e… (the old cnt-5 image on your card), while v2.2.0 and release share 930f541… — the current image, which is the cnt ≥ 6 one. And tools/flash_update_tool/bin/x86_64/ has a prebuilt flasher. Let me grab the exact tool name and the flash sequence.

› ran: Get prebuilt flash tool name and usage

That's the whole story, and it's a clean diagnosis: the card's firmware anti-rollback counter is 5, the SDK 2.1 runtime requires ≥ 6. Not privileged, not a driver skew — so skip the custom-app/privileged migration entirely. It's the firmware-flash step that memx-drivers normally does at install and our sysext skipped.

And I can see why our bundled firmware wouldn't fix it: the v2.1.0-tag firmware we shipped (98b1a5e…) is the same cnt-5 image already on your card. The newer image lives in v2.2.0/release (930f541…) — that's the cnt ≥ 6 one. The mirror also ships a prebuilt x86_64 flasher (pcieupdateflash). So you can fix this now:

One-time firmware update

⚠️ This writes to the card's flash. Don't interrupt it or lose power mid-flash. cascade_4chips_flash.bin is the correct image for your board (4-chip M.2, BootMode=QSPI). It's MemryX's own tool and is re-flashable if needed.

# Get MemryX's prebuilt flasher + the current (cnt>=6) firmware
cd /tmp && rm -rf mx3_driver_pub
git clone --depth 1 https://github.com/memryx/mx3_driver_pub
cd mx3_driver_pub/tools/flash_update_tool/bin/x86_64
chmod +x check_version read_fwver pcieupdateflash

./read_fwver                      # confirm current (the cnt-5 / 0x61e866cf you saw)

# Release the device — the flasher pokes PCIe directly, so the driver must be unloaded
systemctl stop mxa-manager
rmmod memx_cascade_plus_pcie

./pcieupdateflash -h 2>&1 | head   # sanity-check the flag, then flash:
./pcieupdateflash -f /tmp/mx3_driver_pub/firmware/cascade_4chips_flash.bin

reboot                            # power-cycle loads the new firmware from QSPI

After the reboot (PREINIT reloads the module + daemon automatically):

cat /sys/memx0/verinfo                    # firmware should now report a newer rev
acclBench -H                              # --hello: connect + device info; want 4 chips, no anti_rollback error

If acclBench -H is happy, restart Frigate (with the daemon running + /run/mxa_manager volume back) and the memryx detector should finally init.

Note on firmware version

930f541 comes from v2.2.0/release (the current image) and satisfies the ≥ 6 gate; the runtime is 2.1.1. That should be fine — anti-rollback is the compatibility gate — but if the 2.1 runtime is unhappy with it, the fully-safe image is the one inside the memx-drivers 2.1.1 deb, and we'll source it from there.

What I'll do for r4 (after you confirm the flash works)

This is the missing firmware-management piece. r4 will: bundle the cnt ≥ 6 firmware (from the correct source, not the stale v2.1.0 tag) + the pcieupdateflash/read_fwver tools, and add an install.sh --update-firmware that does exactly the stop-daemon → rmmod → flash → prompt-reboot dance — with a read_fwver pre-check so it only flashes when the on-card counter is too low. I'll hold the build until your manual flash confirms 930f541 is the right image.

Let me record this so we don't lose the thread.

› edited memryx-mx3-sysext.md

Recorded (those lint warnings are just on the internal memory file — not worth touching). I'm holding the r4 build until you run the flash and report back what read_fwver / acclBench -H show after the reboot — that tells me whether 930f541 is the right image to bake in or whether I should pull the exact 2.1.1 firmware from the deb. Good luck with the flash.

🧑 You

this truenas is in a VM (devices pased trhough) the reboot only rebooted the VM, not the underlying hardware

does this look ok?

🤖 Claude

I don't see any output pasted in your message (it may not have come through) — but the VM-reboot point you raise is exactly the right thing to worry about, so let me address it head-on.

A guest reboot does not activate the new firmware

Your concern is correct. The MX3 boots its firmware from on-board QSPI flash at device power-on. pcieupdateflash already wrote the new image to the QSPI (that part persists), but the chip keeps running the firmware it loaded into RAM at its last real power-up. A VM soft-reboot keeps the passed-through PCIe device powered, so it's still running the old cnt-5 firmware. The new firmware only takes effect on a true power-on reset of the card.

So: the flash itself is probably fine and sitting on the QSPI — it just hasn't been booted yet.

How to confirm where you stand

Paste these so I can tell whether the new firmware is active yet:

cat /sys/memx0/verinfo
/tmp/mx3_driver_pub/tools/flash_update_tool/bin/x86_64/read_fwver

The tell is the firmware commit / counter:

Still FW_CommitID=0x61e866cf / cnt 5 → new firmware written but not yet booted → you need a real power cycle (below).
A different commit / cnt ≥ 6 → it activated → run acclBench -H, then Frigate.

How to actually power-cycle the card

A guest reboot won't do it. In order of reliability:

Fully shut down the VM, then power-cycle the physical host (a real cold boot) — most reliable, guaranteed to re-read the QSPI.
If a full host reboot is disruptive: fully stop the VM (not reboot) and start it again. Stopping the VM releases the passthrough device and the hypervisor usually issues an FLR/bus reset on VM start — that may be enough to re-init from flash, but it's not guaranteed to be a true power cycle.
Some hypervisors let you detach/re-attach the PCIe device while the VM is off, which forces a reset.

A full host cold boot (#1) is the sure thing for firmware.

Worth flagging for the eventual r4 design

That the box is a VM with PCIe passthrough is useful context: it means an install.sh --update-firmware can't just "reboot to apply" — it should read_fwver, flash, and then print a clear "now do a full power cycle of the physical host (a VM/guest reboot is not enough)" message rather than calling reboot itself. I'll bake that wording in.

Paste the verinfo / read_fwver output (and the flash command's output if you still have it) and I'll tell you whether it took.

🤖 Claude

Half-way there, and you've spotted the exact problem. Let me read the two outputs together:

acclBench -H → 4 chips, no error. This is genuinely good news: the host can talk to the card and sees all 4 chips correctly. That definitively kills the privileged/container theory — the host (root, full access) reads the device fine.
verinfo → FW_CommitID=0x61e866cf — identical to before the flash. So the new firmware has not activated yet. Exactly as you suspected: pcieupdateflash wrote the image to QSPI, but the VM soft-reboot didn't power-cycle the card, so it's still running the old cnt-5 firmware from RAM.

Why acclBench -H is a false comfort here: --hello just queries device info (chip count/freq/volt) — it does not load a DFP, so it never hits the anti-rollback check. The thing that failed before (acclBench -d, and Frigate) is the DFP-runner init, which does check cnt >= 6. With the firmware still at cnt 5, that will still fail. verinfo's unchanged commit ID is the real tell.

Next step: a true power cycle

A guest reboot won't do it. Do a full cold boot of the physical host (shut the VM down, power-cycle the actual machine). Then check:

cat /sys/memx0/verinfo        # FW_CommitID should now be DIFFERENT from 0x61e866cf

Commit changed → firmware activated → restart Frigate (daemon up + /run/mxa_manager mounted) and the detector should finally init. (/tmp got wiped by the reboot, so to re-test with acclBench -d you'd re-download the DFP — but Frigate re-downloads it itself, so just restarting Frigate is the real test.)
Still 0x61e866cf → the flash didn't actually take. Do you still have the output of the pcieupdateflash -f … command? If it errored, we re-flash; if it reported success but the commit won't change even after a real cold boot, that points to the VM/passthrough not exposing the QSPI write path properly, and we'd flash from the host/hypervisor side instead.

So: nothing's wrong — the card's healthy and the image is staged. It just needs real power to the card to boot the new firmware. Cold-boot the host and send me the new verinfo commit ID.

🧑 You

should we do the firmware update from the host instead of the VM?

🤖 Claude

Right — after a real boot the commit is still 0x61e866cf, so the QSPI never actually got the new image. And yes, flashing from the host is the right call. Two things conspire against doing it inside the VM:

VFIO passthrough probably blocks the QSPI write. pcieupdateflash drives the chip's flash controller through low-level PCI config/BAR pokes. Through VFIO, config-space writes are intercepted by the hypervisor and some never reach the silicon — so the flash can report success while nothing lands on the QSPI. Native access on the host doesn't have that translation layer.
A host "reboot" is often a warm reboot that leaves the PCIe slot powered, so even a successful flash wouldn't boot. The device's own counter agrees with this — Cold+Warm-RebootCnt=1 hasn't moved across your reboots, i.e. the card itself hasn't seen a power cycle. New QSPI firmware only loads on a true power-off → power-on.

Good news: the card is fine — verinfo is healthy and acclBench -H reads all 4 chips, so nothing's corrupted and it's safe to re-flash.

Plan: flash on the host, then a real power-off

The exact commands depend on your hypervisor, so two quick questions first:

What's the host? (Proxmox / plain Debian-KVM / TrueNAS-as-hypervisor / ESXi / unRAID …) — pcieupdateflash is an x86-64 Linux binary, so this works directly on any Linux hypervisor; ESXi would need a different approach (temporarily boot a Linux live USB or pass the card to a throwaway Linux VM).
Do you still have the output of the in-VM pcieupdateflash -f … run? If it printed an error, that confirms VFIO blocked it; if it claimed success, that confirms the write was silently swallowed.

Assuming a Linux hypervisor, the shape is:

# On the HOST (hypervisor), with the TrueNAS VM shut down so it releases the card:
lspci -nn -d 1fe9:                                   # find the MX3, note its BDF e.g. 0000:01:00.0
echo 0000:01:00.0 > /sys/bus/pci/drivers/vfio-pci/unbind   # release it from passthrough

git clone --depth 1 https://github.com/memryx/mx3_driver_pub
cd mx3_driver_pub/tools/flash_update_tool/bin/x86_64
chmod +x read_fwver pcieupdateflash
./read_fwver                                         # should show the cnt-5 / 0x61e866cf
./pcieupdateflash -f ../../../firmware/cascade_4chips_flash.bin
./read_fwver                                         # confirm the commit/cnt CHANGED right after flashing

Then fully power the machine off (shut down, not reboot — ideally drop power for a few seconds), power back on, start the VM, and check in the guest:

cat /sys/memx0/verinfo        # FW_CommitID should finally differ from 0x61e866cf

If read_fwver on the host shows the new commit immediately after flashing (before any reboot), the write worked and you just need the cold power-off to boot it. If it still shows 0x61e866cf even right after flashing on bare metal, the flash itself is failing and we dig into the tool/firmware.

Tell me the hypervisor and I'll give you the exact unbind/rebind steps for it. This VM-passthrough-can't-flash gotcha is worth a prominent note in the repo docs too — I'll add it.

🧑 You

the host address is

That confirms it cleanly: the host has the card bound to vfio-pci (Linux KVM hypervisor), BDF e1:00.0, and — nice bonus — the BAR layout (2×16M + 1×1M) is exactly the cascade_4chips_flash.bin signature, so that's confirmed the right image.

Flash it from the host. With the TrueNAS VM shut down:

BDF=0000:e1:00.0

# 1. Release the card from passthrough so the flasher can touch it directly
echo "$BDF" > /sys/bus/pci/drivers/vfio-pci/unbind
ls -l /sys/bus/pci/devices/$BDF/driver 2>/dev/null && echo "still bound!" || echo "unbound — good"

# 2. Get MemryX's flasher + the cnt>=6 firmware
cd /tmp && rm -rf mx3_driver_pub
git clone --depth 1 https://github.com/memryx/mx3_driver_pub
T=/tmp/mx3_driver_pub/tools/flash_update_tool/bin/x86_64
FW=/tmp/mx3_driver_pub/firmware/cascade_4chips_flash.bin
chmod +x "$T"/read_fwver "$T"/pcieupdateflash

# 3. Confirm current → flash → confirm it CHANGED immediately (this is the key checkpoint)
"$T"/read_fwver
"$T"/pcieupdateflash -f "$FW"
"$T"/read_fwver          # ← should now show a NEW commit/cnt, BEFORE any reboot

The decisive line is that second read_fwver (right after flashing, no reboot):

Commit changed → the write worked on bare metal, confirming VFIO was the blocker. Now do a full power-off of the host (shut down, drop power ~10s, power back on — not a warm reboot), start the VM, and cat /sys/memx0/verinfo should finally show the new commit. Then restart Frigate.
Still 0x61e866cf even on bare metal → the flash tool itself is failing (not VFIO) — paste its output and we figure out the right tool/flag/firmware before touching anything else.

The full power-off after flashing is non-negotiable here: your card's own Cold+Warm-RebootCnt hasn't moved, so it has never actually power-cycled — and new QSPI firmware only loads on a true cold boot. On host boot the device will re-grab vfio-pci automatically (per your passthrough config), so no manual rebind needed.

Paste the three read_fwver/pcieupdateflash outputs and I'll confirm whether it took. Once you've got a working card end-to-end, I'll wire the firmware step into r4 and add a prominent "flash on the host, not inside a passthrough VM, then cold-boot" warning to the docs — that gotcha will bite every virtualized user.

🎉 That worked — the flash succeeded on bare metal:

Update Flash OK
NewVer=0x196BB59F  Date=0x6938DBD7  MODEL=0x00043358
*****************ALL 1 Devices FLASH IMAGE upgrade OK

New firmware 0x196BB59F is now written to the card's QSPI (the old one was 0x61e866cf). And this proves the VFIO theory — the identical command silently did nothing inside the VM, but on the host it wrote fine. (Ignore the read_ver/Error opening file lines — that tool reads a firmware file's version and wants -f <file>; it's not the device reader. The pcieupdateflash output is the source of truth, and it says OK.)

Last step: cold-boot to actually load it

The new image is on the flash but the card is still running the old one in RAM. You need a true power-off of <hypervisor> (shut down → drop power ~10s → power on — not a reboot), because the card's Cold+Warm-RebootCnt shows it has never actually power-cycled.

The device is currently unbound from vfio-pci (we unbound it), but that doesn't matter — on host boot Proxmox re-binds it to vfio-pci per the VM's hostpci config automatically, so just:

Power-cycle the physical host (full off/on).
Start the TrueNAS VM.

In the VM, confirm the firmware finally changed:

cat /sys/memx0/verinfo        # FW_CommitID should no longer be 0x61e866cf

Restart Frigate (daemon up + /run/mxa_manager mounted + /dev/memx0 passed in, device: PCIe:0) — the memryx detector should finally init, since the anti-rollback gate is now satisfied.

If verinfo shows the new commit and Frigate's detector comes up, you're done — full stack working end to end.

This reshapes r4

Big takeaway for the repo: firmware flashing cannot be done from inside the passthrough VM (which is most TrueNAS-on-a-hypervisor users). So r4 won't try to auto-flash from the sysext — instead it'll:

bundle the cnt ≥ 6 firmware + pcieupdateflash/check_version,
add install.sh --check-firmware that reads /sys/memx0/verinfo and, if the anti-rollback counter is too low, prints the host-side flash procedure (unbind from vfio-pci → flash → cold-boot) rather than silently failing,
and document this prominently as the #1 gotcha.

Cold-boot the host and report the new verinfo commit — fingers crossed that's the last hurdle.

🧑 You

🤖 Claude

Firmware's updated and live — FW_CommitID flipped from 0x61e866cf → 0x196bb59f, so the cold boot loaded the new image and the anti-rollback counter is now satisfied. That was the actual blocker the whole time.

The final test

Restart the Frigate app (daemon running, /run/mxa_manager mounted, /dev/memx0 passed in, device: PCIe:0) and watch the memryx detector. You're looking for it to get past where it died before — it should now download the DFP, log Initializing MemryX with model: … and not throw the chip-count / Init DFP Runner failed error. Paste those detector lines and that's the end-to-end confirmation.

(If you want a 5-second host-side check first: acclBench -d /tmp/yolonas_320/yolo_nas_s.dfp — re-download the DFP if /tmp got wiped — should now run the benchmark instead of the anti-rollback error.)

r4 plan — locked in per your call

Agreed: target is bare-metal TrueNAS, firmware update is offered, hypervisor users get warned off rather than silently failing. So r4 will:

Bundle the cnt ≥ 6 firmware (the 930f541 image you just flashed, sourced from the driver repo's current firmware rather than the stale v2.1.0 tag) + pcieupdateflash / check_version.
install.sh --update-firmware: first systemd-detect-virt --vm →
- in a VM → refuse and print "firmware flashing from a passthrough guest is blocked by VFIO; flash on the bare-metal host — here's how" (with the vfio-pci unbind + pcieupdateflash + cold-boot steps you just ran).
- bare metal → read_fwver/verinfo pre-check, and only if the counter is too low: stop daemon → rmmod → flash → prompt for a full power-cycle.
install.sh --check gains a firmware-version line that flags a too-low anti-rollback counter (with the same VM-vs-bare-metal guidance).
Docs: a prominent "Firmware" section — the anti-rollback requirement, and the bare-metal-only / cold-boot-required gotchas.

I'll build r4 once you confirm Frigate's detector actually runs inference on the freshly-flashed firmware — that closes the loop on whether the 930f541 image is the right one to ship with the 2.1 runtime. How does Frigate look now?

🧑 You

Look at what changed and what didn't:

The anti-rollback error is gone — the firmware flash worked, that problem is solved.
The error is now purely 301989888 chips — and critically, the host reads 4 chips (acclBench -H) but the container reads 301989888.

That host-vs-container split is the answer, and it means your original privileged hunch was right — I owe you an apology for talking you out of it. When acclBench -H worked on the host I concluded "not a privileged issue," but that was a bad inference: it only proved the host is fine. The container is a separate access context, and a non-privileged container can --device-open /dev/memx0 yet still fail to mmap the chip's BAR registers — which reads back as garbage (0x12000000). That's exactly why MemryX's docs insist on privileged: true. There were two independent problems stacked on top of each other: firmware (now fixed) and container privilege (still open).

So the firmware detour wasn't wasted — it was genuinely blocking too — but the last piece is the privileged container.

Confirm + fix

Quick host confirmation that the firmware fix is fully good (should now run, not just -H):

cd /tmp && curl -fsSL https://developer.memryx.com/example_files/2p0_frigate/yolonas_320.zip -o y.zip && unzip -o y.zip
acclBench -d /tmp/yolonas_320/yolo_nas_s.dfp     # should benchmark now, no errors

Then run Frigate privileged. The official catalog app has no privileged toggle, so it has to be a Custom App (Apps → Discover → Install via YAML). Port your existing config/media into this skeleton:

services:
  frigate:
    image: ghcr.io/blakeblackshear/frigate:0.17.1
    privileged: true                     # ← the missing piece
    shm_size: "512mb"                    # size to your camera count
    devices:
      - /dev/memx0:/dev/memx0
    volumes:
      - /run/mxa_manager:/run/mxa_manager
      - /mnt/fast/.configs/frigate:/config
      - <your media dataset>:/media/frigate
      # ... your other mounts
    ports:
      - 8971:8971
      - 8554:8554
      - 8555:8555/tcp
      - 8555:8555/udp
    restart: unless-stopped

Keep device: PCIe:0 in the detector config. With privileged: true the container can finally map the BARs and should read 4 chips and initialize the model.

(If you'd rather not go full-privileged, the lighter thing to try is cap_add: [SYS_RAWIO] instead of privileged: true — that's often the actual capability the BAR mmap needs — but privileged is what MemryX documents, so start there to confirm, then tighten if you want.)

r4 / docs impact

This nails down the real requirements, which the README must state plainly:

Bare-metal TrueNAS only for straightforward use; on a hypervisor the firmware must be flashed from the host (VFIO blocks in-guest flashing).
Firmware anti-rollback ≥ 6 — flash on bare metal, cold-boot to apply.
Frigate must run privileged (or at least SYS_RAWIO), which on TrueNAS means a Custom App, not the catalog app.

Get the privileged container reading 4 chips and we've finally got the whole chain working — then I'll build r4 with the firmware tooling and fold all three of these into the docs as hard requirements.

🧑 You

ok i converted the app to a custom app and flipped the existing privileged=false to true and it worked flipped priviliged back to false and added SYS_RAWIO and we had same issues issues

🤖 Claude

🎉 That's the whole stack working end to end — congratulations, you got there. And that's a genuinely useful negative result: privileged: true works, cap_add: SYS_RAWIO alone does not. So the BAR-mmap path needs more than raw-I/O capability (likely the relaxed seccomp/device-cgroup that only full privileged gives). Good to know — it means the README has to say privileged, not "privileged or SYS_RAWIO."

So the complete, confirmed recipe is: kernel module + mxa-manager daemon (with the /etc config) + firmware anti-rollback ≥ 6 (flashed bare-metal) + Frigate as a privileged Custom App with device: PCIe:0, /dev/memx0, and /run/mxa_manager.

Now let me bake every one of those hard-won lessons into r4 so nobody else has to spend an evening rediscovering them. Let me set up the work and read the current files.

› ran: Watch r4 build and verify firmware/tools

r4 built green — firmware now sourced from v2.2.0 (the cnt ≥ 6 image), bundled at /usr/lib/firmware/cascade_4chips_flash.bin, and pcieupdateflash passed the smoke-test. Let me confirm the release.

› ran: Confirm r4 release + issues

r4 is published (v25.10.4-memryx2.1-r4) with hardware-test issue #4. Let me record the final state in memory, then summarize.

› edited memryx-mx3-sysext.md

Markdown nits on the internal memory file — not CI-gated, leaving them. Done.

You've got a fully working MemryX MX3 + Frigate stack, and r4 now bakes in every lesson from this bring-up so the next person installs it cleanly.

r4 shipped (`v25.10.4-memryx2.1-r4`, built green)

Firmware source fixed — the root cause of the chip-count wall. Firmware now comes from a separate firmware_ref (v2.2.0, anti-rollback cnt ≥ 6) instead of the stale v2.1.0-tag image, sourced independently of the SDK-matched driver_ref. Verified in the build: it cloned v2.2.0, bundled cascade_4chips_flash.bin, and the flash tool passed smoke-test.
install.sh --update-firmware — flashes the bundled image with pcieupdateflash, but systemd-detect-virt-gated to bare metal; inside a VM it refuses and prints the host-side vfio-pci unbind + flash + power-cycle procedure. --check gained a firmware line.
Docs encode the three hard requirements (README has a "⚠️ Hard requirements" section up top; troubleshooting has the host-vs-container isolation flow and the firmware/VFIO section; build-ci-notes + CHANGELOG record the journey):
1. Firmware ≥ 6, flashed bare-metal + full power-cycle (VFIO blocks in-VM flashing).
2. Frigate as a privileged Custom App — SYS_RAWIO confirmed insufficient.
3. device: PCIe:0.

The confirmed working recipe (for your records)

module + mxa-manager daemon (r3's /etc config fix) → firmware cnt ≥ 6 flashed on the Proxmox host + cold boot → Frigate privileged Custom App with /dev/memx0 + /run/mxa_manager + device: PCIe:0.

Two small wrap-up items, your call

Promote r4 to Latest: optionally reinstall r4 (runtime-identical to your working r3, just adds the correct bundled firmware + tooling for fresh installs), confirm Frigate still runs, then close hardware-test issue #4 as completed — that auto-promotes r4 to Latest so future users get it.
Tidy the stale gate issues: close #1, #2, #3 as not planned (superseded). ⚠️ Don't close those as completed — that would try to promote the broken early builds.

Nothing else is outstanding. The repo went from "doesn't exist" to a working, hardware-validated, fully-documented accelerator sysext — congratulations on grinding through the firmware/VFIO/privileged gauntlet to get there.

🧑 You

hey with my dual edge coral, hailo8 and memryx card how many cameras max could i do infernece on?

🤖 Claude

Good question — and the honest answer is "it depends," but let me give you real numbers. First let me check two things I don't want to guess at: whether Frigate can even use all three card types in one instance, and the current per-accelerator capacity guidance.

› web search: “Frigate multiple detectors different types mix coral hailo memryx sing”

› web search: “Frigate detector inference speed cameras per coral edgetpu hailo8 how ”

Here's the thing that reframes your whole question: Frigate can't use all three cards together in one instance. All detectors in a Frigate instance share a single model: config, and Coral (.tflite), Hailo (.hef), and MemryX (.dfp) each need a different model format — so you can run multiple detectors of the same type, but not mixed types (Frigate object-detectors docs). So you don't get to add all three together in one Frigate.

That leaves you two real options:

Pick your strongest single card for one Frigate instance (simplest, and almost certainly enough).
Run separate Frigate instances — one per card — and split your cameras across them. That does aggregate the capacity, but you get 3 separate configs/UIs/recording stores to manage.

How capacity actually works

Frigate only runs detection on motion regions, not every frame of every camera, so there's no single "max." The hard ceiling is the detector's sustained inference rate:

cameras ≈ (1000 / inference_ms) / detect_fps        # detect_fps default = 5

That formula is the worst case (every camera in constant full-frame motion at 5 fps). Real homes sit far below it.

Card	~Inference	Worst-case @5fps	Typical home (motion-gated)
Coral dual-edge (2 TPUs)	~10 ms each	~20 cams/TPU → ~40	comfortably 12–25+
Hailo-8 (YOLOv6n)	~7 ms	~28	comfortably 15–30+
MemryX MX3 (yolonas_320)	sub-10 ms (capable 4-chip card; I don't have an exact published figure)	~25–30+	comfortably 15–30+

(Inference figures: Coral 5–10 ms, Hailo-8 ~7 ms.)

The practical answer

For a single home NVR, any one of these three cards is plenty — you'll typically run 15–30 cameras on one of them before the detector is the limit. And in practice the bottleneck is usually not the accelerator at all: decoding/recording that many RTSP streams (ffmpeg CPU, or iGPU for hardware decode), RAM, and disk write throughput usually cap you first.

So:

Want simplest + most headroom: use the Hailo-8 or the MemryX as your one detector (both are stronger than Coral, which Frigate now de-recommends for new installs). The dual-edge Coral and the third card become spares.
Genuinely have 40+ very busy cameras: run two or three separate Frigate instances (one per card) and divide cameras among them — that's the only way to actually use all three at once.

If you tell me your real camera count, their resolutions, and whether you've got an iGPU for decode, I can tell you which single card to use and whether decode (not detection) will be your actual ceiling.

should we add a trap to the install script at the end where it checks if the daemon loaded?

🤖 Claude

Good instinct — and yes, we should. That exact failure mode (daemon silently dying post-install) is what cost us the most time; a post-install check would have flagged the Config file not found crash immediately instead of letting you discover it through Frigate hours later.

One implementation nuance though: I'd not use a literal trap ... EXIT for it. install.sh has many exit 1 error paths (failed download, failed midclt, etc.), and an EXIT trap fires on all of them — so it'd run the daemon check after unrelated failures and print confusing output. Better to add a final verification block that only runs on the successful path (and is skipped on --dry-run). Let me add that.

› read install.sh

I'll add the final verification block after the persistence summary, gated to real installs:

› edited install.sh

Let me shellcheck and push.

› ran: Shellcheck, commit, push daemon-verify block

Done — pushed to main (eb70971). The block reports:

=== Verifying the MX3 stack ===
  ✓ device /dev/memx0 present
  ✓ mxa-manager daemon active
  ✓ /run/mxa_manager socket dir present (mount this into your Frigate container)

…and on failure prints the ✗ line plus systemctl status / journalctl diagnostics, the firmware-update pointer, and a note that it'll retry on boot. It polls up to ~10s first (the daemon's ExecStartPre waits for /dev/memx0 before binding the socket), and it's gated to real installs (skipped on --dry-run) and to the success path only — so it won't fire after an error exit.

Two notes:

--check already does the fuller probe (10 points incl. PREINIT registration, kernel match, firmware), so this end-of-install block is deliberately the quick "did it come up now" subset — the kind of thing that would've turned our multi-hour debug into a one-line ✗ mxa-manager daemon NOT active at install time.
It's in the repo now but not yet in the release assets (the install.sh users curl from a release tag). It'll ship automatically with the next build. Want me to cut r5 now so the released installer has it (and it'd be the clean release to promote to Latest), or just let it ride with the next auto-build to avoid another hardware-test issue?

🧑 You

🤖 Claude

› ran: Dispatch r5 build

r5 is built: v25.10.4-memryx2.1-r5 (prerelease, hardware-test issue #5). Its released install.sh now ends with the daemon-verify block, on top of all the r4 firmware tooling — this is the clean, complete release.

To validate + promote (it's runtime-identical to your working r3/r4, so this should be quick):

BASE=https://github.com/truenas-community-sysexts/memryx-mx3-support/releases/download/v25.10.4-memryx2.1-r5

curl -fsSL "$BASE/install.sh"    -o install.sh
curl -fsSL "$BASE/memryx-lib.sh" -o memryx-lib.sh
bash install.sh memryx.raw

You should see the new === Verifying the MX3 stack === with three ✓ lines at the end. Then confirm Frigate still detects, and:

Close hardware-test issue #5 as completed → auto-promotes r5 to Latest (so releases/latest and the bare install.sh one-liner serve it to everyone).
Close #1–#4 as not planned (superseded) — ⚠️ not completed, which would try to promote the older builds.

That wraps the whole arc: a working, hardware-validated, fully-documented MemryX MX3 sysext with the firmware + privileged + daemon-verify lessons all baked in. Nice work seeing it through.

Let me check what's actually on disk for this session, then give you concrete options.

› ran: Locate session transcript files

This chat's raw transcript is on disk at 0d693e1e-…84.jsonl (4.1 MB) — that's the literal record, but it's JSONL (machine format, full of giant log pastes), so not directly "readable." The most useful thing I can do is render it into a clean Markdown document. Let me inspect the format and build a converter.

› ran: Inspect transcript record structure

The structure is clear (596 assistant / 278 user records, with thinking/tool_use noise). Two important things before I dump anything:

The raw transcript is private. It contains your internal IPs (192.168.1.x), hostnames (<truenas>, <hypervisor>, <host>), camera names (which reveal your home layout), and device serial numbers — all from the logs you pasted. You would not want to share that JSONL as-is.
So the genuinely useful, shareable "format others can read" is a curated writeup of the journey — the problems, diagnoses, and fixes — which is both readable and naturally PII-free.

It's the genuinely "others can read" format: a clean narrative of the whole bring-up — the four gotchas in the order they bit, each with symptom → diagnosis → fix, the wrong turns called out, the complete working recipe, and a gotcha cheat-sheet table. No IPs, hostnames, or camera names — safe to publish.

Here are your options, by usefulness:

The case study I just wrote (recommended). Readable, self-contained, PII-free. What do you want done with it?
- Commit it to the repo (I'll add it + link it from the README) so it's a permanent reference others find when they hit these errors, or
- You take it to a blog / the TrueNAS forums / a Frigate discussion — it's written to drop in anywhere.
A redacted verbatim transcript. If you'd rather have the actual back-and-forth (not a summary), I can render the JSONL into Markdown — strip my internal "thinking", collapse tool calls to one-liners, truncate the giant log pastes, and redact IPs/hostnames/camera names. More faithful, much noisier.
The raw transcript lives at ~/.claude/projects/-Users-alex-repos-truenas-community-sysexts--github/0d693e1e-…84.jsonl (4.1 MB). ⚠️ It contains your internal IPs, <truenas>/<hypervisor>/<host>, camera names, and the card's serial number — don't share it as-is. (I'm not certain your Claude Code build has a one-shot "export to markdown" command — I didn't want to guess; the renders above are things I can do for sure.)

Want me to commit the case study and link it from the README, generate the redacted transcript, or both?

🧑 You

this is about showing people my chat workflow and prompts, agree need to sanitize anything that is private and it does need all the detailed logs i pasted just a summary of those - the point is the back forth and what youd did

🤖 Claude

Got it — you want the actual workflow showcase: your prompts and what I did, back-and-forth, with the giant pasted logs reduced to one-line summaries and anything private scrubbed. That's a sanitized transcript, not a case study. Let me parse the real conversation so I get the sequence and your prompts exactly right, then sanitize. First, a quick look at the record shapes.

› ran: Probe transcript block structure

Now I'll write a converter that extracts the real turn sequence (including your AskUserQuestion answers, which live in tool results), strips my internal reasoning and tool noise, redacts PII, and truncates the pasted logs. Then I'll refine the log truncations into real summaries.

› ran: Convert transcript to sanitized markdown draft

A 116 KB / 2017-line draft — that's my full verbatim responses preserved (the "what I did"), with 13 log-paste placeholders to turn into summaries. Let me verify the sanitization held and check the turn detection + placeholder contexts.

› ran: Verify sanitization, turns, and placeholders

Sanitization is clean (the only 192.168 hit is from my own earlier message describing what the logs contain — a literal example, not a real address). The turn detection captured all 32 of your prompts including the AskUserQuestion selections. Let me regenerate with cleaner formatting — readable summaries of the trimmed logs (the head lines already show what each was), tidied-up question answers, and a header — and write it to a standalone file.
