[PATCH 02/43] drm/i915: add crtc->enable/disable vfuncs insted of dpms

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Because that's what we're essentially calling. This is the first step
in untangling the crtc_helper induced dpms handling mess we have - at
the crtc level we only have 2 states and the magic is just in selectin
which one (and atm there isn't even much magic, but on recent
platforms where not even the crt output has more than 2 states we
could do better).
