Ville Syrjälä c631cc8f11 drm/i915: Make a copy of the ggtt view for slave plane ... intel_prepare_plane_fb() will always pin plane_state->hw.fb whenever it is present. We copy that from the master plane to the slave plane, but we fail to copy the corresponding ggtt view. Thus when it comes time to pin the slave plane's fb we use some stale ggtt view left over from the last time the plane was used as a non-slave plane. If that previous use involved 90/270 degree rotation or remapping we'll try to shuffle the pages of the new fb around accordingingly. However the new fb may be backed by a bo with less pages than what the ggtt view rotation/remapped info requires, and so we we trip a GEM_BUG(). Steps to reproduce on icl: 1. plane 1: whatever plane 6: largish !NV12 fb + 90 degree rotation 2. plane 1: smallish NV12 fb plane 6: make invisible so it gets slaved to plane 1 3.
