| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Due to wrong `.. kernel-doc` directive in Documentation/gpu/rfc/gpusvm.rst the documentation was actually not parsing anything from drivers/gpu/drm/drm_gpusvm.c. This fixes the kernel-doc include and all warnings/errors created when doing so.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This code is based on the RDMA and misc cgroup initially, but now uses page_counter. It uses the same min/low/max semantics as the memory cgroup as a result. There's a small mismatch as TTM uses u64, and page_counter long pages. In practice it's not a problem. 32-bits systems don't really come with >=4GB cards and as long as we're consistently wrong with units, it's fine. The device page size may not be in the same units as kernel page size, and each region might also have a different page size (VRAM vs GART for example). The interface is simple: - Call dmem_cgroup_register_region() - Use dmem_cgroup_try_charge to check if you can allocate a chunk of memory, use dmem_cgroup__uncharge when freeing it. This may return an error code, or -EAGAIN when the cgroup limit is reached. In that case a reference to the limiting pool is returned. - The limiting cs can be used as compare function for dmem_cgroup_state_evict_valuable. - After having evicted enough, drop reference to limiting cs with dmem_cgroup_pool_state_put. This API allows you to limit device resources with cgroups. You can see the supported cards in /sys/fs/cgroup/dmem.capacity You need to echo +dmem to cgroup.subtree_control, and then you can partition device memory.

In practice the only driver which emits these keys is amdgpu and in them exposes the current resident buffer object memory (including shared). To prevent any confusion, document that drm-memory- is deprecated and an alias for drm-resident-memory-. While at it also clarify that the reserved sub-string 'memory' refers to the memory region component, and also clarify the intended semantics of other memory categories. v2: * Also mark drm-memory- as deprecated. * Add some more text describing memory categories. (Alex) v3: * Semantics of the amdgpu drm-memory is actually as drm-resident.

| * | | drm/panthor: add sysfs knob for enabling job profilingAdrián Larumbe2024-10-021-0/+46
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This commit introduces a DRM device sysfs attribute that lets UM control the job accounting status in the device. The knob variable had been brought in as part of a previous commit, but now we're able to fix it manually. As sysfs files are part of a driver's uAPI, describe its legitimate input values and output format in a documentation file.
