Opensource GPU Drivers BoF
summary
Status update on mainline ARM GPU support: vc4/v3d run on products (v3d uses an MMU; vc4 remains CMA and shows OOM pains), Lima and Panfrost kernel drivers are landing (Lima awaiting Linus merge; Panfrost is in Mesa), kernel driver merged, GT test on three Midgard GPUs proves basic GL ES and compositor work, OpenCL follows a planned CLC->LLVM->SPIR-V path into NIR, common pieces like a job scheduler from AMD and DRM memory helpers reduce duplication, and CI plus buffer-import/fence work continue while an ARM cache-flush gap still needs addressing.
