After thinking it over a lot it made more sense for the core to deal with the output polling especially so it can notify X. v2: drop plans for fake connector - per Michel's comments - fix X patch sent to xorg-devel, add intel polled/hpd setting, add initial nouveau polled/hpd settings. v3: add config lock take inside polling, add intel/nouveau poll init/fini calls v4: config lock was a bit agressive, only needed around connector list reading. otherwise it could re-enter. glisse: discard drm_helper_hpd_irq_event v3: Reviewed-by: Michel Dänzer <michel@daenzer.net> Signed-off-by: Dave Airlie <airlied@redhat.com>
