2019-09-13drm/amdgpu: Avoid HW GPU reset for RAS.Andrey Grodzovsky
Problem: Under certain conditions, when some IP bocks take a RAS error, we can get into a situation where a GPU reset is not possible due to issues in RAS in SMU/PSP. Temporary fix until proper solution in PSP/SMU is ready: When uncorrectable error happens the DF will unconditionally broadcast error event packets to all its clients/slave upon receiving fatal error event and freeze all its outbound queues, err_event_athub interrupt will be triggered. In such case and we use this interrupt to issue GPU reset. THe GPU reset code is modified for such case to avoid HW reset, only stops schedulers, deatches all in progress and not yet scheduled job's fences, set error code on them and signals. Also reject any new incoming job submissions from user space. All this is done to notify the applications of the problem. v2: Extract amdgpu_amdkfd_pre/post_reset from amdgpu_device_lock/unlock_adev Move amdgpu_job_stop_all_jobs_on_sched to amdgpu_job.c Remove print param from amdgpu_ras_query_error_count v3: Update based on prevoius bug fixing patch to properly call amdgpu_amdkfd_pre_reset for other XGMI hive memebers.

2019-09-13drm/amdgpu: Fix bugs in amdgpu_device_gpu_recover in XGMI case.Andrey Grodzovsky
Issue 1: In XGMI case amdgpu_device_lock_adev for other devices in hive was called to late, after access to their repsective schedulers. So relocate the lock to the begining of accessing the other devs. Issue 2: Using amdgpu_device_ip_need_full_reset to switch the device list from all devices in hive to the single 'master' device who owns this reset call is wrong because when stopping schedulers we iterate all the devices in hive but when restarting we will only reactivate the 'master' device. Also, in case amdgpu_device_pre_asic_reset conlcudes that full reset IS needed we then have to stop schedulers for all devices in hive and not only the 'master' but with amdgpu_device_ip_need_full_reset we already missed the opprotunity do to so. So just remove this logic and always stop and start all schedulers for all devices in hive. Also minor cleanup and print fix. v4: Minor coding style fix.
