drm/amdgpu: rename vram_scratch into mem_scratch

2023-01-03T21:50:03+00:00

Rename vram_scratch into mem_scratch and allow allocating it into GTT as well. The only problem with that is that we won't have a default page for the system aperture any more. Signed-off-by: Christian König Signed-off-by: Luben Tuikov Acked-by: Felix Kuehling Signed-off-by: Alex Deucher

drm/amdgpu: Remove ATC L2 access for MMHUB 2.1.x

2022-10-24T18:34:26+00:00

MMHUB 2.1.x versions don't have ATCL2. Remove accesses to ATCL2 registers. Since they are non-existing registers, read access will cause a 'Completer Abort' and gets reported when AER is enabled with the below patch. Tagging with the patch so that this is backported along with it. v2: squash in uninitialized warning fix (Nathan Chancellor) Fixes: 8795e182b02d ("PCI/portdrv: Don't disable AER reporting in get_port_device_capability()") Signed-off-by: Lijo Lazar Reviewed-by: Guchun Chen Signed-off-by: Alex Deucher Cc: stable@vger.kernel.org

drm/amdgpu: convert IP version array to include instances

2021-10-04T19:23:01+00:00

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

drm/amdgpu/mmhub2.0: convert to IP version checking

drm/amdgpu: correct clock gating settings on feature unsupported

2021-06-30T04:18:22+00:00

Clock gating setting is still performed even when the corresponding CG feature is not supported. And the tricky part is disablement is actually performed no matter for enablement or disablement request. That seems not logically right. Considering HW should already properly take care of the CG state, we will just skip the corresponding clock gating setting when the feature is not supported.

KMD should not program these registers, the value were defined in the host, so skip them in the SRIOV environment. Signed-off-by: Peng Ju Zhou Reviewed-by: Alex Deucher Signed-off-by: Alex Deucher
