From: Trigger Huang <Trigger.Huang@xxxxxxx> Add new separate parameter to control GPU coredump procedure. This can be used to decouple the coredump procedure from gpu recovery procedure V2: enable gpu_coredump by default (Alex) Signed-off-by: Trigger Huang <Trigger.Huang@xxxxxxx> --- drivers/gpu/drm/amd/amdgpu/amdgpu.h | 1 + drivers/gpu/drm/amd/amdgpu/amdgpu_drv.c | 8 ++++++++ 2 files changed, 9 insertions(+) diff --git a/drivers/gpu/drm/amd/amdgpu/amdgpu.h b/drivers/gpu/drm/amd/amdgpu/amdgpu.h index 937de21a7142..4dd465ad14af 100644 --- a/drivers/gpu/drm/amd/amdgpu/amdgpu.h +++ b/drivers/gpu/drm/amd/amdgpu/amdgpu.h @@ -201,6 +201,7 @@ extern uint amdgpu_force_long_training; extern int amdgpu_lbpw; extern int amdgpu_compute_multipipe; extern int amdgpu_gpu_recovery; +extern int amdgpu_gpu_coredump; extern int amdgpu_emu_mode; extern uint amdgpu_smu_memory_pool_size; extern int amdgpu_smu_pptable_id; diff --git a/drivers/gpu/drm/amd/amdgpu/amdgpu_drv.c b/drivers/gpu/drm/amd/amdgpu/amdgpu_drv.c index b9529948f2b2..06bd20d83db7 100644 --- a/drivers/gpu/drm/amd/amdgpu/amdgpu_drv.c +++ b/drivers/gpu/drm/amd/amdgpu/amdgpu_drv.c @@ -178,6 +178,7 @@ uint amdgpu_force_long_training; int amdgpu_lbpw = -1; int amdgpu_compute_multipipe = -1; int amdgpu_gpu_recovery = -1; /* auto */ +int amdgpu_gpu_coredump = 1; int amdgpu_emu_mode; uint amdgpu_smu_memory_pool_size; int amdgpu_smu_pptable_id = -1; @@ -556,6 +557,13 @@ module_param_named(compute_multipipe, amdgpu_compute_multipipe, int, 0444); MODULE_PARM_DESC(gpu_recovery, "Enable GPU recovery mechanism, (1 = enable, 0 = disable, -1 = auto)"); module_param_named(gpu_recovery, amdgpu_gpu_recovery, int, 0444); +/** + * DOC: gpu_coredump (int) + * Set to enable GPU coredump mechanism (1 = enable, 0 = disable).
