From 1d789535a03679e5ce0b56a0d32a5e44596dfcdb Mon Sep 17 00:00:00 2001 From: Alex Deucher Date: Mon, 4 Oct 2021 15:19:10 -0400 Subject: drm/amdgpu: convert IP version array to include instances MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Allow us to query instances versions more cleanly. Instancing support is not consistent unfortunately. SDMA is a good example. Sienna cichlid has 4 total SDMA instances, each enumerated separately (HWIDs 42, 43, 68, 69). Arcturus has 8 total SDMA instances, but they are enumerated as multiple instances of the same HWIDs (4x HWID 42, 4x HWID 43). UMC is another example. On most chips there are multiple instances with the same HWID. This allows us to support both forms. v2: rebase v3: clarify instancing support Reviewed-by: Christian König Signed-off-by: Alex Deucher --- drivers/gpu/drm/amd/amdgpu/amdgpu.h | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'drivers/gpu/drm/amd/amdgpu/amdgpu.h') diff --git a/drivers/gpu/drm/amd/amdgpu/amdgpu.h b/drivers/gpu/drm/amd/amdgpu/amdgpu.h index b153c3740307..f4bceb2624fb 100644 --- a/drivers/gpu/drm/amd/amdgpu/amdgpu.h +++ b/drivers/gpu/drm/amd/amdgpu/amdgpu.h @@ -1096,7 +1096,7 @@ struct amdgpu_device { struct pci_saved_state *pci_state; struct amdgpu_reset_control *reset_cntl; - uint32_t ip_versions[HW_ID_MAX]; + uint32_t ip_versions[HW_ID_MAX][HWIP_MAX_INSTANCE]; }; static inline struct amdgpu_device *drm_to_adev(struct drm_device *ddev) -- cgit
