2025-05-13gpu: nova-core: define registers layout using helper macroAlexandre Courbot
Add the register!() macro, which defines a given register's layout and provide bit-field accessors with a way to convert them to a given type. This macro will allow us to make clear definitions of the registers and manipulate their fields safely. The long-term goal is to eventually move it to the kernel crate so it can be used by other drivers as well, but it was agreed to first land it into nova-core and make it mature there. To illustrate its usage, use it to define the layout for the Boot0 (renamed to NV_PMC_BOOT_0 to match OpenRM's naming scheme) and take advantage of its accessors.

2025-04-08drm: Add UAPI for the Asahi driverAlyssa Rosenzweig
This adds the UAPI for the Asahi driver targeting the GPU in the Apple M1 and M2 series systems on chip. The UAPI design is based on other modern Vulkan-capable drivers, including Xe and Panthor. Memory management is based on explicit VM management. Synchronization is exclusively explicit sync. This UAPI is validated against our open source Mesa stack, which is fully conformant to the OpenGL 4.6, OpenGL ES 3.2, OpenCL 3.0, and Vulkan 1.4 standards. The Vulkan driver supports sparse, exercising the VM_BIND mechanism. This patch adds the standalone UAPI header. It is implemented by an open source DRM driver written in Rust. We fully intend to upstream this driver when possible. However, as a production graphics driver, it depends on a significant number of Rust abstractions that will take a long time to upstream. In the mean time, our userspace is upstream in Mesa but is not allowed to probe with upstream Mesa as the UAPI is not yet reviewed and merged in the upstream kernel. Although we ship a patched Mesa in Fedora Asahi Remix, any containers shipping upstream Mesa builds are broken for our users, including upstream Flatpak and Waydroid runtimes. Additionally, it forces us to maintain forks of Mesa and virglrenderer, which complicates bisects. The intention in sending out this patch is for this UAPI to be thoroughly reviewed. Once we as the DRM community are satisfied with the UAPI, this header lands signifying that the UAPI is stable and must only be evolved in backwards-compatible ways; it will be the UAPI implemented in the DRM driver that eventually lands upstream. That promise lets us enable upstream Mesa, solving all these issues while the upstream Rust abstractions are developed. https://github.com/alyssarosenzweig/linux/commits/agx-uapi-v7 contains the DRM driver implementing this proposed UAPI. https://gitlab.freedesktop.org/mesa/mesa/-/merge_requests/33984 contains the Mesa patches to implement this proposed UAPI. That Linux and Mesa branch together give a complete graphics/compute stack on top of this UAPI.

2025-03-12drm/ci: enable lockdep detectionVignesh Raman
We have enabled PROVE_LOCKING (which enables LOCKDEP) in drm-ci. This will output warnings when kernel locking errors are encountered and will continue executing tests. To detect if lockdep has been triggered, check the debug_locks value in /proc/lockdep_stats after the tests have run. When debug_locks is 0, it indicates that lockdep has detected issues and turned itself off. Check this value, and if lockdep is detected, exit with an error and configure it as a warning in GitLab CI. GitLab CI ignores exit codes other than 1 by default. Pass the correct exit code with variable FF_USE_NEW_BASH_EVAL_STRATEGY set to true or exit on failure. Also update the documentation.

2025-03-09gpu: nova-core: add initial documentationDanilo Krummrich
Add the initial documentation of the Nova project. The initial project documentation consists out of a brief introduction of the project, as well as project guidelines both general and nova-core specific and a task list for nova-core specifically. The task list is divided into tasks for general Rust infrastructure required by the project, tasks regarding GSP enablement and firmware abstraction, general GPU driver tasks as well as tasks related to external API design and test infrastructure.

2025-03-09drm/nouveau/nvkm: factor out current GSP RPC command policiesZhi Wang
There can be multiple cases of handling the GSP RPC messages, which are the reply of GSP RPC commands according to the requirement of the callers and the nature of the GSP RPC commands. The current supported reply policies are "callers don't care" and "receive the entire message" according to the requirement of the callers. To introduce a new policy, factor out the current RPC command reply polices. Also, centralize the handling of the reply in a single function. Factor out NVKM_GSP_RPC_REPLY_NOWAIT as "callers don't care" and NVKM_GSP_RPC_REPLY_RECV as "receive the entire message". Introduce a kernel doc to document the policies. Factor out r535_gsp_rpc_handle_reply(). No functional change is intended for small GSP RPC commands. For large GSP commands, the caller decides the policy of how to handle the returned GSP RPC message.

Users can check the file "/sys/kernel/debug/dri/0/amdgpu_firmware_info" to get information on the firmware loaded in the system. This file has multiple acronyms that are not documented in the glossary. This commit introduces some missing acronyms to the AMD glossary documentation. The meaning of each acronym in this commit was extracted from code documentation available in the following files: - drivers/gpu/drm/amd/amdgpu/gfx_v7_0.c - drivers/gpu/drm/amd/include/amd_shared.h Changes since v1: - Expand acronym meanings based on Alex Deucher suggestions.
