This patchset addresses two issues affecting UVD initialization on CIK hardware: * Patch #1 fixes init with <256M vram: (https://gitlab.freedesktop.org/drm/amd/-/issues/3448) * Patch #2 fixes init with >256M vram: (https://gitlab.freedesktop.org/drm/amd/-/issues/3851) Includes a whitespace fix for the version on the issue tracker. [Request for Testing]
Patch #2 tries to preserve the existing vcpu bo allocation behavior for UVD 5.0+. However, I don't have any UVD 5.0+ hardware available for regression testing. If someone with a GCN3-5 card can confirm this patchset does not break UVD 5.0+ init, it'd be greatly appreciated.
