2017-10-19drm/amdgpu: SR-IOV data exchange between PF&VFHorace Chen1-0/+178
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.

2017-09-28drm/amdgpu: fix vf error handlingAlex Deucher1-0/+13
The error handling for virtual functions assumed a single vf per VM and didn't properly account for bare metal. Make the error arrays per device and add locking. Reviewed-by: Gavin Wan <[email protected]> Signed-off-by: Alex Deucher <[email protected]>

2017-07-14drm/amdgpu: Support passing amdgpu critical error to host via GPU Mailbox.Gavin Wan1-0/+1
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.

2017-03-29drm/amdgpu:add lock_reset for SRIOVMonk Liu1-0/+1
this lock is used for sriov_gpu_reset, only get this mutex can run into sriov_gpu_reset. we have couple source triggers gpu_reset for SRIOV: 1) submit timedout and trigger reset voluntarily 2) invalid instruction detected by ENGINE and trigger reset voluntarily 2) hypervisor found world switch hang and trigger flr and notify guest to do reset. all need take care and we need a mutex to protect the consistency of reset routine.
