Hello Alex,
I get this in dmesg:
[ 26.001926] [drm:radeon_atom_pick_dig_encoder [radeon]] *ERROR*
chosen
encoder in use 4
What do you need?
The message is harmless I think. It's just debugging output from the
DP MST patches. I think what's happening is that when you change the
mode on an encoder that is already enabled, it see that the encoder is
already in use (by itself). I think the fix would be to call
radeon_atom_release_dig_encoder() in the encoder prepare callback, but
I'm not sure if that will negatively affect MST or not. Dave?
well we can drop the message down to debug_kms, I'll have a look
to see if we need to do a release there, its probably safe but I'd have
to
test it.
Dave.
Fixed in (new) drm-next-4.1-wip by commit:
2248a6a41473e4a77391a2163284fe0683eac165
Thanks Dave and Alex!
-Dieter
