From AI Studio analysis of https://github.com/google/angle/blob/6a04a50f98cac71b25464d10289ce7a013841caf/src/libANGLE/renderer/vulkan/vk_renderer.cpp#L4879

1. ARM / Mali

These workarounds apply to GPUs designed by ARM (Mali), found in chipsets like Samsung Exynos, Google Tensor, and MediaTek Dimensity.

Feature / Workaround	mFeatures Flag	Condition / Driver Version	Reason & Impact
Protected Memory Restriction	supportsProtectedMemory	Blocked if: isARM && !pipelineProtectedAccess	Bug: On older ARM platforms, enabling VK_KHR_protected_memory causes excessive, unnecessary load/store unit activity. Workaround: Only enabled on ARM if the newer VK_EXT_pipeline_protected_access extension is also present, indicating a fixed driver. (b/208458772)
Mixed Load Op Restriction	disallowMixedDepthStencilLoadOpNoneAndLoad	Enabled if: isARM && driverVersion < r38.1.0	Bug: ARM drivers older than r38p1 are bug
