Series | Display Stream Compression (DSC) for AMD Navi | expand |
What branch does this patch series actually apply to? I've been trying to apply this locally, but it doesn't appear to apply against drm-tip/drm-tip, amdgpu-next/drm-next, or origin (e.g. kernel.org) /master. Is there any chance we could have this go against drm-tip instead (and even better, split out the DRM-specific bits into their own patch series?)

I was building against amd-staging-drm-next (commit e4a67e6cf14c). v4 will contain just the drm-mst patches and will apply on latest drm-tip/drm-tip (commit 018886de4726)
