drm/amdgpu: Check if fd really is an amdgpu fd.

2019-02-15T16:15:37Z

Otherwise we interpret the file private data as drm & amdgpu data while it might not be, possibly allowing one to get memory corruption. Signed-off-by: Bas Nieuwenhuizen Reviewed-by: Christian König Signed-off-by: Alex Deucher

drm/amdgpu: Fix sdma doorbell range setting

2019-01-25T21:15:34Z

Different ASIC has different SDMA queue number so different SDMA doorbell range. Introduce an extra parameter to sdma_doorbell_range function and set sdma doorbell range correctly. Signed-off-by: Oak Zeng Reviewed-by: Philip Yang Signed-off-by: Alex Deucher

drm/amdgpu: add need_reset_on_init asic callback (v2)

2019-01-14T20:04:55Z

Used to determine if we need to reset the asic on init due to the driver having been previously loaded or not shutdown cleanly. E.g., kexec or VM passthrough. v2: rebase Reviewed-by: Evan Quan Reviewed-by: Felix Kuehling Signed-off-by: Alex Deucher

drm/amdgpu: Add sysfs file for PCIe usage v5

2019-01-14T20:04:54Z

Add a sysfs file that reports the number of bytes transmitted and received in the last second. This can be used to approximate the PCIe bandwidth usage over the last second. v2: Clarify use of mps as estimation of bandwidth v3: Don't make the file on APUs v4: Early exit for APUs in the read function, change output to display "packets-received packets-sent mps" v5: fix missing header for si (Alex) Signed-off-by: Kent Russell Reviewed-by: Felix Kuehling Reviewed-by: Alex Deucher Signed-off-by: Alex Deucher

We don't want KFD processes evicting each other over VRAM usage. Therefore prevent overcommitting VRAM among KFD applications with a per-GPU limit. Also leave enough room for page tables on top of the application memory usage. Acked-by: Alex Deucher Signed-off-by: Felix Kuehling Reviewed-by: Eric Huang Signed-off-by: Alex Deucher

drm/amdgpu: Refactor GPU reset for XGMI hive case

2018-11-28T20:55:36Z

For XGMI hive case do reset in steps where each step iterates over all devs in hive. This especially important for asic reset since all PSP FW in hive must come up within a limited time (around 1 sec) to properply negotiate the link. Do this by refactoring amdgpu_device_gpu_recover and amdgpu_device_reset into pre_asic_reset, asic_reset and post_asic_reset functions where is part is exectued for all the GPUs in the hive before going to the next step. v2: Update names for amdgpu_device_lock/unlock functions. v3: Introduce per hive locking to avoid multiple resets for GPUs in same hive. v4: Remove delayed_workqueue()/ttm_bo_unlock_delayed_workqueue() - they are copy & pasted over from radeon and on amdgpu there isn't any reason for that any more.
