From 6c8d1f4b042e706ccd7575beb0397a75d545d71b Mon Sep 17 00:00:00 2001 From: "Jesse.zhang@amd.com" Date: Tue, 5 Nov 2024 15:22:56 +0800 Subject: drm/amdgpu: Add sysfs interface for gc reset mask Add two sysfs interfaces for gfx and compute: gfx_reset_mask compute_reset_mask These interfaces are read-only and show the resets supported by the IP. For example, full adapter reset (mode1/mode2/BACO/etc), soft reset, queue reset, and pipe reset. V2: the sysfs node returns a text string instead of some flags (Christian) v3: add a generic helper which takes the ring as parameter and print the strings in the order they are applied (Christian) check amdgpu_gpu_recovery before creating sysfs file itself, and initialize supported_reset_types in IP version files (Lijo) v4: Fixing uninitialized variables (Tim) Signed-off-by: Jesse Zhang Suggested-by: Alex Deucher Reviewed-by: Tim Huang Signed-off-by: Alex Deucher --- drivers/gpu/drm/amd/amdgpu/amdgpu_gfx.h | 2 ++ 1 file changed, 2 insertions(+) (limited to 'drivers/gpu/drm/amd/amdgpu/amdgpu_gfx.h') diff --git a/drivers/gpu/drm/amd/amdgpu/amdgpu_gfx.h b/drivers/gpu/drm/amd/amdgpu/amdgpu_gfx.h index fd73e527f446..8b5bd63b5773 100644 --- a/drivers/gpu/drm/amd/amdgpu/amdgpu_gfx.h +++ b/drivers/gpu/drm/amd/amdgpu/amdgpu_gfx.h @@ -424,6 +424,8 @@ struct amdgpu_gfx { /* reset mask */ uint32_t grbm_soft_reset; uint32_t srbm_soft_reset; + uint32_t gfx_supported_reset; + uint32_t compute_supported_reset; /* gfx off */ bool gfx_off_state; /* true: enabled, false: disabled */ -- cgit v1.2.3
