[Nouveau] [PATCH 1/1] drm/nouveau/disp: prefer identity-mapped route of SOR <-> macro link

With DCB 4.1 implemented by VBIOS since GM20x GPUs, SOR crossbar routing should be possible, such that any SOR sublink can drive any macro link. Therefore, if crossbar routing is available, the first suitable SOR was picked. Unfortunately, there's at least one card where some SORs being being

[Nouveau] [PATCH 0/1] drm/nouveau/disp: prefer identity-mapped route of SOR <-> macro link

Hi Ben, still _assuming_ it's an issue of the card I thought about why it works with the NVIDIA binary driver. And I can image they're just trying to do an identity-mapping first and if that doesn't work (e.g. the particular SOR is already in use by another macro link) they just pick the next

With DCB 4.1 implemented by VBIOS since GM20x GPUs, SOR crossbar routing should be possible, such that any SOR sublink can drive any macro link. Unfortunately, there's at least one card where some SOR sublinks being connected to a particular macro link are causing failures. To work around this
