2017-10-19drm/amdgpu: SR-IOV data exchange between PF&VFHorace Chen1-0/+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.

2017-07-14drm/amdgpu: Support passing amdgpu critical error to host via GPU Mailbox.Gavin Wan1-20/+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.

2017-05-24drm/amdgpu:need som change on vega10 mailboxMonk Liu1-8/+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.
