| | | | | | | | | | | | | | This was only used as workaround for recovering the page tables after VRAM was lost and is no longer necessary after the function amdgpu_vm_bo_reset_state_machine() started to do the same. Compute never used shadows either, so the only proplematic case left is SVM and that is most likely not recoverable in any way when VRAM is lost.

| * drm/amdgpu: Implement Enforce Isolation Handler for KGD/KFD serializationSrinivasan Shanmugam2024-08-211-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| * drm/amdgpu: Add enforce_isolation sysfs attributeSrinivasan Shanmugam2024-08-211-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| * drm/amdgpu: Make enforce_isolation setting per GPUSrinivasan Shanmugam2024-08-161-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 <[email protected]> Cc: Alex Deucher <[email protected]> Signed-off-by: Srinivasan Shanmugam <[email protected]> Signed-off-by: Alex Deucher <[email protected]> Suggested-by: Christian König <[email protected]>

| | | | | | | | | | | | | | | | | | | | | | | | With WBRF feature supported, as a driver responding to the frequencies, amdgpu driver is able to do shadow pstate switching to mitigate possible interference(between its (G-)DDR memory clocks and local radio module frequency bands used by Wifi 6/6e/7). -- v1->v2: - update the prompt for feature support(Lijo) v8->v9: - update parameter document for smu_wbrf_event_handler(Simon) v9->v10: v10->v11: - correct the logics for wbrf range sorting(Lijo) v13: - Fix the format issue (IIpo Jarvinen) Signed-off-by: Evan Quan <[email protected]> Reviewed-by: Mario Limonciello <[email protected]> Signed-off-by: Ma Jun <[email protected]> Signed-off-by: Ma Jun <[email protected]> Signed-off-by: Alex Deucher <[email protected]>

* drm/amdgpu: Implement a new 64bit sequence memory driverArunpravin Paneer Selvam2023-11-171-0/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Developed a new driver which allocates a 64bit memory on each request in sequence order. At the moment, user queue fence memory is the main consumer of this seq64 driver. v2: Worked on review comments from Christian for the following modifications - Move driver name from "semaphore" to "seq64" - Remove unnecessary PT/PD mapping - Move enable_mes check into init/fini functions. v3: Worked on review comments from Christian - drop enable_mes check - use DECLARE_BITMAP for bit array - added kerneldoc for seq64 v4: Worked on review comments from Christian - Rename amdgpu_seq64_get name with amdgpu_seq64_alloc v5: Worked on review comments from Christian - Fix seq64 lockdep warning - move fpriv->seq64_va check into amdgpu_seq64_unmap() - make the function amdgpu_seq64_unmap() return as void. - reserve the buffers as not interruptible. v6: port to drm_exec (Alex) v7: disable for now (Arun) Signed-off-by: Arunpravin Paneer Selvam <[email protected]> Reviewed-by: Christian König <[email protected]> Signed-off-by: Alex Deucher <[email protected]>
* drm/amdgpu: add a module parameter to control the AGP apertureAlex Deucher2023-11-171-0/+1
| | | | | | | | | | | | | | | | Add a module parameter to control the AGP aperture. The AGP aperture is an aperture in the GPU's internal address space which provides direct non-paged access to the platform address space. This access is non-snooped so only uncached memory can be accessed. Add a knob so that we can toggle this for debugging.
