2024-12-18drm/amdgpu: Optimize gfx v9 GPU page fault handlingPhilip Yang5-1/+84
After GPU page fault, there are lots of page fault interrupts generated at short period even with CAM filter enabled because the fault address is different. Each page fault copy to KFD ih fifo to send event to user space by KFD interrupt worker, this could cause KFD ih fifo overflow while other processes generate events at same time. KFD process is aborted after GPU page fault, we only need one GPU page fault interrupt sent to KFD ih fifo to send memory exception event to user space. Incease KFD ih fifo size to 2 times of IH primary ring size, to handle the burst events case. This patch handle the gfx v9 path, cover retry on/off and CAM filter on/off cases.

2024-12-18drm/amdkfd: KFD interrupt access ih_fifo data in-placePhilip Yang1-21/+14
To handle 40000 to 80000 interrupts per second running CPX mode with 4 streams/queues per KFD node, KFD interrupt handler becomes the performance bottleneck. Remove the kfifo_out memcpy overhead by accessing ih_fifo data in-place and updating rptr with kfifo_skip_count.

2024-12-18Revert "drm/amd/display: Fix green screen issue after suspend"Rodrigo Siqueira3-24/+13
This reverts commit 87b7ebc2e16c14d32a912f18206a4d6cc9abc3e8. A long time ago, we had an issue with the Raven system when it was connected to two displays: one with DP and another with HDMI. After the system woke up from suspension, we saw a solid green screen caused by an underflow generated by bad DCC metadata. To workaround this issue, the 'commit 87b7ebc2e16c ("drm/amd/display: Fix green screen issue after suspend")' was introduced to disable the DCC for a few frames after in the resume phase. However, in hindsight, this solution was probably a workaround at the kernel level for some issues from another part (probably other driver components or user space). After applying this patch and trying to reproduce the green issue in a similar hardware system but using the latest kernel and userspace, we cannot see the issue, which makes this workaround obsolete and creates extra unnecessary complexity to the code; for all of this reason, this commit reverts the original change.

Since 2320c9e6a768 ("drm/sched: memset() 'job' in drm_sched_job_init()") accessing job->base.sched can produce unexpected results as the initialisation of (*job)->base.sched done in amdgpu_job_alloc is overwritten by the memset. This commit fixes an issue when a CS would fail validation and would be rejected after job->num_ibs is incremented. In this case, amdgpu_ib_free(ring->adev, ...) will be called, which would crash the machine because the ring value is bogus. To fix this, pass a NULL pointer to amdgpu_ib_free(): we can do this because the device is actually not used in this function. The next commit will remove the ring argument completely.
