2024-08-29drm/amdgpu: skip printing vram_lost if neededTrigger Huang
The vm lost status can only be obtained after a GPU reset occurs, but sometimes a dev core dump can be happened before GPU reset. So a new argument is added to tell the dev core dump implementation whether to skip printing the vram_lost status in the dump. And this patch is also trying to decouple the core dump function from the GPU reset function, by replacing the argument amdgpu_reset_context with amdgpu_job to specify the context for core dump.

2024-08-20drm/amdgpu: Implement Enforce Isolation Handler for KGD/KFD serializationSrinivasan Shanmugam
This commit introduces the Enforce Isolation Handler designed to enforce shader isolation on AMD GPUs, which helps to prevent data leakage between different processes. The handler counts the number of emitted fences for each GFX and compute ring. If there are any fences, it schedules the `enforce_isolation_work` to be run after a delay of `GFX_SLICE_PERIOD`. If there are no fences, it signals the Kernel Fusion Driver (KFD) to resume the runqueue. The function is synchronized using the `enforce_isolation_mutex`. This commit also introduces a reference count mechanism (kfd_sch_req_count) to keep track of the number of requests to enable the KFD scheduler. When a request to enable the KFD scheduler is made, the reference count is decremented. When the reference count reaches zero, a delayed work is scheduled to enforce isolation after a delay of GFX_SLICE_PERIOD. When a request to disable the KFD scheduler is made, the function first checks if the reference count is zero. If it is, it cancels the delayed work for enforcing isolation and checks if the KFD scheduler is active. If the KFD scheduler is active, it sends a request to stop the KFD scheduler and sets the KFD scheduler state to inactive. Then, it increments the reference count. The function is synchronized using the kfd_sch_mutex to ensure that the KFD scheduler state and reference count are updated atomically.

2024-08-20drm/amdgpu: Add enforce_isolation sysfs attributeSrinivasan Shanmugam
This commit adds a new sysfs attribute 'enforce_isolation' to control the 'enforce_isolation' setting per GPU. The attribute can be read and written, and accepts values 0 (disabled) and 1 (enabled). When 'enforce_isolation' is enabled, reserved VMIDs are allocated for each ring. When it's disabled, the reserved VMIDs are freed. The set function locks a mutex before changing the 'enforce_isolation' flag and the VMIDs, and unlocks it afterwards. This ensures that these operations are atomic and prevents race conditions and other concurrency issues.

2024-08-16drm/amdgpu: Make enforce_isolation setting per GPUSrinivasan Shanmugam
This commit makes enforce_isolation setting to be per GPU and per partition by adding the enforce_isolation array to the adev structure. The adev variable is set based on the global enforce_isolation module parameter during device initialization. In amdgpu_ids.c, the adev->enforce_isolation value for the current GPU is used to determine whether to enforce isolation between graphics and compute processes on that GPU. In amdgpu_ids.c, the adev->enforce_isolation value for the current GPU and partition is used to determine whether to enforce isolation between graphics and compute processes on that GPU and partition. This allows the enforce_isolation setting to be controlled individually for each GPU and each partition, which is useful in a system with multiple GPUs and partitions where different isolation settings might be desired for different GPUs and partitions. v2: fix loop in amdgpu_vmid_mgr_init() (Alex) Cc: Christian König <christian.koenig@amd.com> Cc: Alex Deucher <alexander.deucher@amd.com> Signed-off-by: Srinivasan Shanmugam <srinivasan.shanmugam@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com> Suggested-by: Christian König <christian.koenig@amd.com>
