| H A D | i915_drm.h | 08d7b3d1 Wed Apr 29 16:43:54 CDT 2009 Carl Worth <cworth@cworth.org> drm/i915: Add new GET_PIPE_FROM_CRTC_ID ioctl.
This allows userlevel code to discover the pipe number corresponding
to a given CRTC ID. This is necessary for doing pipe-specific
operations such as waiting for vblank on a given CRTC. Failure to use
the right pipe mapping can result in GPU hangs, or at least failure
to actually sync to vblank.
