a=openpgp; fpr=CD3F328C177AEF322D9FFF8379A829E70C5E7DEB 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() - Initialization of Command Stream Frontend (CSF) firmware interfaces Dependencies: - [PATCH v12 0/5] Rust bindings for gem shmem https://lore.kernel.org/rust-for-linux/20260421235346.672794-1-lyude@redhat.com - [PATCH v6 0/5] Rust GPUVM immediate mode https://lore.kernel.org/rust-for-linux/20260409-gpuvm-rust-v6-0-b16e6ada7261@google.com/ - [PATCH v6 0/5] Introduce DeviceContext https://lore.kernel.org/rust-for-linux/20260320233645.950190-1-lyude@redhat.com/ - [PATCH v5 0/6] drm/tyr: Use register! macro https://lore.kernel.org/rust-for-linux/20260409-b4-tyr-use-register-macro-v5-v5-0-8abfff8a0204@collabora.com/ Other Prerequisites: This series also depends on additional prerequisite fixes not included in this posting.
