Could we do the same with a per-devnode debugfs file for mst? The topology manager sits on top of the dp aux abstraction, so this could work, with s/encoder->name/dp_aux->name/. Would give us mst info on every driver for free (plus we could nuke the ad-hoc version in i915). -Daniel > > drivers/gpu/drm/nouveau/dispnv50/disp.c | 34 ---------------- > drivers/gpu/drm/nouveau/dispnv50/disp.h | 35 +++++++++++++++++ > drivers/gpu/drm/nouveau/nouveau_debugfs.c | 47 ++++++++++++++++++++++- > 3 files changed, 80 insertions(+), 36 deletions(-) > > -- > 2.17.1 > -- Daniel Vetter Software Engineer, Intel Corporation http://blog.ffwll.ch _______________________________________________ dri-devel mailing list dri-devel@xxxxxxxxxxxxxxxxxxxxx https://lists.freedesktop.org/mailman/listinfo/dri-devel
