drm/amdgpu: fix sriov host flr handler

2024-06-14T20:15:58+00:00

We send back the ready to reset message before we stop anything. This is wrong. Move it to when we are actually ready for the FLR to happen. In the current state since we take tens of seconds to stop everything, it is very likely that host would give up waiting and reset the GPU before we send ready, so it would be the same as before. But this gets rid of the hack with reset_domain locking and also let us tell how slow ready to reset actually is from the host. The ready to reset speed can be improved later.

drm/amdgpu: Add reset_context flag for host FLR

2024-05-02T19:40:50+00:00

There are other reset sources that pass NULL as the job pointer, such as amdgpu_amdkfd_reset_work. Therefore, using the job pointer to check if the FLR comes from the host does not work. Add a flag in reset_context to explicitly mark host triggered reset, and set this flag when we receive host reset notification.

drm/amdgpu: Fix two reset triggered in a row

2024-05-02T19:40:44+00:00

Some times a hang GPU causes multiple reset sources to schedule resets. The second source will be able to trigger an unnecessary reset if they schedule after we call amdgpu_device_stop_pending_resets. Move amdgpu_device_stop_pending_resets to after the reset is done. Since at this point the GPU is supposedly in a good state, any reset scheduled after this point would be a legitimate reset. Remove unnecessary and incorrect checks for amdgpu_in_reset that was kinda serving this purpose. Signed-off-by: Yunxiang Li Reviewed-by: Lijo Lazar Signed-off-by: Alex Deucher

This reverts commit dac6b80818ac2353631c5a33d140d8d5508e2957. This commit reverted the AMDGPU_SKIP_MODE2_RESET as it conflicts with the original design of reset handler. Will redesign it.

Move reset_context out of gpu recover function to make it configurable for different reset purpose. For the reset way of call gpu_recovery sysfs, force to use full reset method. Otherwise, try soft reset by default if the related ASIC supportted, if soft reset failed, will use full reset. Signed-off-by: Likun Gao Reviewed-by: Hawking Zhang Signed-off-by: Alex Deucher

drm/amdgpu: Rework reset domain to be refcounted.

2022-02-09T17:17:09+00:00

The reset domain contains register access semaphor now and so needs to be present as long as each device in a hive needs it and so it cannot be binded to XGMI hive life cycle. Adress this by making reset domain refcounted and pointed by each member of the hive and the hive itself. v4: Fix crash on boot witrh XGMI hive by adding type to reset_domain. XGMI will only create a new reset_domain if prevoius was of single device type meaning it's first boot. Otherwsie it will take a refocunt to exsiting reset_domain from the amdgou device. Add a wrapper around reset_domain->refcount get/put and a wrapper around send to reset wq (Lijo) Signed-off-by: Andrey Grodzovsky Acked-by: Christian König Link: https://www.spinics.net/lists/amd-gfx/msg74121.html
