* drm/amdgpu:implement new GPU recover(v3)Monk Liu2017-12-041-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 1,new imple names amdgpu_gpu_recover which gives more hint on what it does compared with gpu_reset 2,gpu_recover unify bare-metal and SR-IOV, only the asic reset part is implemented differently 3,gpu_recover will increase hang job karma and mark its entity/context as guilty if exceeds limit V2: 4,in scheduler main routine the job from guilty context will be immedialy fake signaled after it poped from queue and its fence be set with "-ECANCELED" error 5,in scheduler recovery routine all jobs from the guilty entity would be dropped 6,in run_job() routine the real IB submission would be skipped if @skip parameter equales true or there was VRAM lost occured. V3: 7,replace deprecated gpu reset, use new gpu recover Signed-off-by: Monk Liu <Monk.Liu@amd.com> Reviewed-by: Christian König <christian.koenig@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>

* drm/amdgpu: SR-IOV data exchange between PF&VFHorace Chen2017-10-191-0/+6
| | | | | | | | | | | | | | | | | SR-IOV need to exchange some data between PF&VF through shared VRAM PF will copy some necessary firmware and information to the shared VRAM. It also requires some information from VF. PF will send a key through mailbox2 to help guest calculate checksum so that it can verify whether the data is correct. So check the data on the specified offset of the shared VRAM, if the checksum is right, read values from it and write some VF information next to the data from PF.

* drm/amdgpu: Support passing amdgpu critical error to host via GPU Mailbox.Gavin Wan2017-07-141-20/+26
| | | | | | | | | | | | | | This feature works for SRIOV enviroment. For non-SRIOV enviroment, the trans_error function does nothing. The error information includes error_code (16bit), error_flags(16bit) and error_data(64bit). Since there are not many errors, we keep the errors in an array and transfer all errors to Host before amdgpu initialization function (amdgpu_device_init) exit.

* drm/amdgpu:need som change on vega10 mailboxMonk Liu2017-05-241-8/+10
| | | | | | | | | | | | | | | | | | | | | if sriov gpu reset is invoked by job timeout, it is run in a global work-queue which is very slow and better not call msleep ortherwise it takes long time to get back CPU. so make below changes: 1: Change msleep 1 to mdelay 5 2: Ignore the ack fail from pf after time out, because VF FLR will clear ack, sometime VF FLR is done prior to the beginning of poll_ack so we can ignore this ack TODO: Put job_timedout (and the following gpu reset) in a driver thread, instead of the global work_struct.
