Ben Skeggs 6c22ea3747 drm/nouveau/disp: introduce acquire/release display path methods ... These exist to give NVKM information on the set of display paths that the DD needs to be active at any given time. Previously, the supervisor attempted to determine this solely from OR state, but there's a few configurations where this information on its own isn't enough to determine the specific display paths in question: - ANX9805, where the PIOR protocol for both DP and TMDS is TMDS. - On a device using DCB Switched Outputs. - On GM20x and newer, with a crossbar between the SOR and macro links. After this commit, the DD tells NVKM *exactly* which display path it's attempting a modeset on. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>		2017-06-16 14:04:57 +10:00
