From: Trigger Huang <[email protected]> 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 drivers/gpu/drm/amd/amdgpu/amdgpu.h | 3 + drivers/gpu/drm/amd/amdgpu/amdgpu_device.c | 89 ++++++++++++++++++---- drivers/gpu/drm/amd/amdgpu/amdgpu_drv.c | 8 ++ drivers/gpu/drm/amd/amdgpu/amdgpu_job.c | 10 +++ 4 files changed, 97 insertions(+), 13 deletions(-) -- 2.34.1
