From 59fd50b8663b4e703b44f9b51a2e715dc6e344c1 Mon Sep 17 00:00:00 2001 From: "Jesse.zhang@amd.com" Date: Mon, 4 Nov 2024 13:15:49 +0800 Subject: drm/amdgpu: Add sysfs interface for sdma reset mask Add the sysfs interface for sdma: sdma_reset_mask The interface is 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) Signed-off-by: Jesse Zhang Suggested-by: Alex Deucher Reviewed-by: Tim Huang Signed-off-by: Alex Deucher --- drivers/gpu/drm/amd/amdgpu/amdgpu_sdma.h | 3 +++ 1 file changed, 3 insertions(+) (limited to 'drivers/gpu/drm/amd/amdgpu/amdgpu_sdma.h') diff --git a/drivers/gpu/drm/amd/amdgpu/amdgpu_sdma.h b/drivers/gpu/drm/amd/amdgpu/amdgpu_sdma.h index a37fcd9bb981..2db58b5812a8 100644 --- a/drivers/gpu/drm/amd/amdgpu/amdgpu_sdma.h +++ b/drivers/gpu/drm/amd/amdgpu/amdgpu_sdma.h @@ -116,6 +116,7 @@ struct amdgpu_sdma { struct ras_common_if *ras_if; struct amdgpu_sdma_ras *ras; uint32_t *ip_dump; + uint32_t supported_reset; }; /* @@ -176,4 +177,6 @@ void amdgpu_sdma_destroy_inst_ctx(struct amdgpu_device *adev, bool duplicate); int amdgpu_sdma_ras_sw_init(struct amdgpu_device *adev); void amdgpu_debugfs_sdma_sched_mask_init(struct amdgpu_device *adev); +int amdgpu_sdma_sysfs_reset_mask_init(struct amdgpu_device *adev); +void amdgpu_sdma_sysfs_reset_mask_fini(struct amdgpu_device *adev); #endif -- cgit v1.2.3-70-g09d2
