Revert "drm/amd: Stop evicting resources on APUs in suspend"

2025-05-07T22:24:04Z

This reverts commit 3a9626c816db901def438dc2513622e281186d39. This breaks S4 because we end up setting the s3/s0ix flags even when we are entering s4 since prepare is used by both flows. The causes both the S3/s0ix and s4 flags to be set which breaks several checks in the driver which assume they are mutually exclusive.

drm/amd: Forbid suspending into non-default suspend states

2025-04-16T19:52:20Z

On systems that default to 'deep' some userspace software likes to try to suspend in 'deep' first. If there is a failure for any reason (such as -ENOMEM) the failure is ignored and then it will try to use 's2idle' as a fallback. This fails, but more importantly it leads to graphical problems. Forbid this behavior and only allow suspending in the last state supported by the system.

drm/amdgpu: Increase KIQ invalidate_tlbs timeout

2025-04-07T19:18:30Z

KIQ invalidate_tlbs request has been seen to marginally exceed the configured 100 ms timeout on systems under load. All other KIQ requests in the driver use a 10 second timeout. Use a similar timeout implementation on the invalidate_tlbs path. v2: Poll once before msleep v3: Fix return value Signed-off-by: Jay Cornwall Cc: Kent Russell Reviewed-by: Harish Kasiviswanathan Signed-off-by: Alex Deucher

drm/amdgpu: rework how isolation is enforced v2

2025-03-21T16:16:34Z

Limiting the number of available VMIDs to enforce isolation causes some issues with gang submit and applying certain HW workarounds which require multiple VMIDs to work correctly. So instead start to track all submissions to the relevant engines in a per partition data structure and use the dma_fences of the submissions to enforce isolation similar to what a VMID limit does. v2: use ~0l for jobs without isolation to distinct it from kernel submissions which uses NULL for the owner. Add some warning when we are OOM. Signed-off-by: Christian König Acked-by: Srinivasan Shanmugam Signed-off-by: Alex Deucher

drm/amdgpu: Create a debug option to disable ring reset

2025-02-27T21:50:04Z

Prior to the addition of ring reset, the debug option `debug_disable_soft_recovery` could be used to force a full device reset. Now that we have ring reset, create a debug option to disable them in amdgpu, forcing the driver to go with the full device reset path again when both options are combined. This option is useful for testing and debugging purposes when one wants to test the full reset from userspace. Signed-off-by: André Almeida Signed-off-by: Alex Deucher

drm/amdgpu: Optimize the enablement of GECC

2025-02-17T19:09:29Z

Enable GECC only when the default memory ECC mode or the module parameter amdgpu_ras_enable is activated. v2: Add kernel message to remind users explicitly set amdgpu_ras_enable=1 before driver loading to enable GECC and set amdgpu_ras_enable=0 to disable GECC when GECC is currently enabled if needed.

drm/amdkfd: add a new flag to manage where VRAM allocations go

2025-02-13T02:04:08Z

On big and small APUs we send KFD VRAM allocations to GTT since the carve out is either non-existent or relatively small. However, if someone sets the carve out size to be relatively large, we may end up using GTT rather than VRAM. No change of logic with this patch, but it allows the driver to determine which logic to use based on the carve out size in the future. Reviewed-by: Mario Limonciello Signed-off-by: Alex Deucher

drm/amdgpu: partially revert "reduce reset time"

2024-12-18T17:39:07Z

This partially reverts commit 194eb174cbe4fe2b3376ac30acca2dc8c8beca00. This commit introduced a new state variable into adev without even remotely worrying about CPU barriers. Since we already have the amdgpu_in_reset() function exactly for this use case partially revert that. Signed-off-by: Christian König Reviewed-by: Alex Deucher Signed-off-by: Alex Deucher
