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

drm/amd: Add Suspend/Hibernate notification callback support

2024-12-10T15:26:50Z

As part of the suspend sequence VRAM needs to be evicted on dGPUs. In order to make suspend/resume more reliable we moved this into the pmops prepare() callback so that the suspend sequence would fail but the system could remain operational under high memory usage suspend. Another class of issues exist though where due to memory fragementation there isn't a large enough contiguous space and swap isn't accessible. Add support for a suspend/hibernate notification callback that could evict VRAM before tasks are frozen. This should allow paging out to swap if necessary.

drm/amdgpu: Add init level for post reset reinit

2024-11-20T15:03:05Z

When device needs to be reset before initialization, it's not required for all IPs to be initialized before a reset. In such cases, it needs to identify whether the IP/feature is initialized for the first time or whether it's reinitialized after a reset. Add RESET_RECOVERY init level to identify post reset reinitialization phase. This only provides a device level identification, IP/features may choose to track their state independently also.

drm/amdgpu: Add sysfs interface for gc reset mask

2024-11-08T16:08:01Z

Add two sysfs interfaces for gfx and compute: gfx_reset_mask compute_reset_mask These interfaces are read-only and show the resets supported by the IP. For example, full adapter reset (mode1/mode2/BACO/etc), soft reset, queue reset, and pipe reset. V2: the sysfs node returns a text string instead of some flags (Christian) v3: add a generic helper which takes the ring as parameter and print the strings in the order they are applied (Christian) check amdgpu_gpu_recovery before creating sysfs file itself, and initialize supported_reset_types in IP version files (Lijo) v4: Fixing uninitialized variables (Tim) Signed-off-by: Jesse Zhang Suggested-by: Alex Deucher Reviewed-by: Tim Huang Signed-off-by: Alex Deucher

drm/amdgpu: fix fairness in enforce isolation handling

2024-11-04T16:27:04Z

Make sure KFD gets a turn when serializing access to the GC IP. Currently non-KFD jobs can starve KFD if they submit often enough. This patch prevents that by stalling non-KFD if its time period has elapsed. v2: fix units v3: check enablement properly Acked-by: Srinivasan Shanmugam Signed-off-by: Alex Deucher

drm/amdgpu: clean up the suspend_complete

2024-10-28T20:40:58Z

To check the status of S3 suspend completion, use the PM core pm_suspend_global_flags bit(1) to detect S3 abort events. Therefore, clean up the AMDGPU driver's private flag suspend_complete. Signed-off-by: Prike Liang Reviewed-by: Lijo Lazar Signed-off-by: Alex Deucher
