2023-06-15drm/amdgpu: expose num_hops and num_links xgmi info through dev attrShiwu Zhang
Add these two dev attrs for xgmi info details which is helpful for developers checking the xgmi topology by catting the sys file directly. Take 4 cards with xgmi connection as an example, get the num_hops for each device or node through xmig_hive_info dir like, cat /sys/bus/pci/devices/0000:41:00.0/xgmi_hive_info/node1/num_hops will return "00 41 41 41" where "00" stands for the hops to node1 itself and "41" is the hops in hex format to every other node in the same hive. There are node1/node2/node3/node4 representing 4 cards in the hive. The same for num_links dev attr.

The number of hops and the number of links must be accumulated by the driver. Other data points are all fetched from the first request.

2020-08-24drm/amdgpu: Get DRM dev from adev by inline-fLuben Tuikov
Add a static inline adev_to_drm() to obtain the DRM device pointer from an amdgpu_device pointer. Signed-off-by: Luben Tuikov <luben.tuikov@amd.com> Reviewed-by: Alex Deucher <alexander.deucher@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>
2020-08-24drm/amdgpu: drm_device to amdgpu_device by inline-f (v2)Luben Tuikov
Get the amdgpu_device from the DRM device by use of an inline function, drm_to_adev(). The inline function resolves a pointer to struct drm_device to a pointer to struct amdgpu_device. v2: Use a typed visible static inline function instead of an invisible macro.

2020-08-24drm/amdgpu: refine create and release logic of hive infoDennis Li
Change to dynamically create and release hive info object, which help driver support more hives in the future. v2: Change to save hive object pointer in adev, to avoid locking xgmi_mutex every time when calling amdgpu_get_xgmi_hive. v3: 1. Change type of hive object pointer in adev from void* to amdgpu_hive_info*. 2. remove unnecessary variable initialization.

2020-08-24drm/amdgpu: refine codes to avoid reentering GPU recoveryDennis Li
if other threads have holden the reset lock, recovery will fail to try_lock. Therefore we introduce atomic hive->in_reset and adev->in_gpu_reset, to avoid reentering GPU recovery. v2: drop "? true : false" in the definition of amdgpu_in_reset Reviewed-by: Hawking Zhang <Hawking.Zhang@amd.com> Signed-off-by: Dennis Li <Dennis.Li@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>
2020-08-14drm/amdgpu: revert "fix system hang issue during GPU reset"Christian König
The whole approach wasn't thought through till the end. We already had a reset lock like this in the past and it caused the same problems like this one. Completely revert the patch for now and add individual trylock protection to the hardware access functions as necessary. This reverts commit df9c8d1aa278c435c30a69b8f2418b4a52fcb929.
