But, we'll need this in a moment so -that we can share mode validation between SST and MST which will fix -some real world issues. - -Signed-off-by: Lyude Paul <lyude@redhat.com> -Signed-off-by: Ben Skeggs <bskeggs@redhat.com> ---- - drivers/gpu/drm/nouveau/dispnv50/disp.c | 25 ++++++++++++++----------- - 1 file changed, 14 insertions(+), 11 deletions(-) - -diff --git a/drivers/gpu/drm/nouveau/dispnv50/disp.c b/drivers/gpu/drm/nouveau/dispnv50/disp.c -index 1db4f20b8697..e92e7bf49780 100644 ---- a/drivers/gpu/drm/nouveau/dispnv50/disp.c -+++ b/drivers/gpu/drm/nouveau/dispnv50/disp.c -@@ -908,15 +908,9 @@ nv50_msto_atomic_check(struct drm_encoder *encoder, - if (!state->duplicated) { - const int clock = crtc_state->adjusted_mode.clock; - -- /* -- * XXX: Since we don't use HDR in userspace quite yet, limit -- * the bpc to 8 to save bandwidth on the topology.
