[PATCH 0/3] Improve the dev coredump

[Trigger.Huang at amd.com]

From: Trigger Huang <Trigger.Huang at amd.com>

The current dev coredump implementation sometimes cannot fully satisfy customer's requirements due to:
1, The enablement of dev coredump is under the control of gpu_recovery. Customer can not do dev coredump with gpu_recovery disabled
2, When job timeout happened, the dump GPU status will be happened after a lot of operations, like soft_reset. The concern here is that the status is not so close to the real GPU's error status.

So we introduced a new solution
1, A new parameter, gpu_coredump, is added to decouple the coredump and gpu reset
2, Do the coredump immediately after a job timeout

Trigger Huang (3):
  drm/amdgpu: Add gpu_coredump parameter
  drm/amdgpu: introduce new API for GPU core dump
  drm/amdgpu: Change the timing of doing coredump
