drm/amdgpu: Support passing amdgpu critical error to host via GPU Mailbox.

2017-07-14T15:05:52+00:00

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 mailbox

2017-05-24T21:40:18+00:00

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.
