This series adds firmware loading and MCU boot support to the Tyr DRM
driver. It includes:
- A parser for the Mali CSF firmware binary format
- A kernel-managed BO type (KernelBo) for internal driver allocations
- GPU virtual memory (VM) integration using drm_gpuvm
- An MMU module and a generic slot manager
- Shmem-backed GEM support for Tyr
- Loading firmware, VM activation, and MCU boot at probe()
Base:
drm-rust-next-2026-01-26
commit cea7b66a8041 ("Documentation: nova: update pending tasks")
