Displayport 1.1 only uses the short form to request link retraining usually, so we haven't really needed support for it until now. However with DP 1.2 MST we need to handle the short irqs on their own outside the modesetting locking the long hpd's involve. This patch adds the framework to distinguish between short/long to the current code base, to lay the basis for future DP 1.2 MST work. This should mean we get better bisectability in case of regression due to the new irq handling. v2: add GM45 support (untested, due to lack of hw) Signed-off-by: Dave Airlie <airlied@redhat.com> Reviewed-by: Todd Previte <tprevite@gmail.com> [danvet: Fix conflicts in i915_irq.c with Oscar Mateo's irq handling race fixes and a trivial one in intel_drv.h with the psr code.] Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch> :040000 040000 7be50985e66c24e64d4de3cccbdcd521ef59903b 8e9cf7373e1c96e78989fd0514e8da8debaad1c4 M drivers The commit unable to revert.
