Atomic Mode-Setting / Nuclear Page-Flipping

Rob Clark of Texas Instruments talked more at length today during XDC2012 about the atomic mode-setting / nuclear page-flipping plans.

This work revolves around the atomic patches that were published earlier this month. As said earlier, the introduced "drm_flip" mechanism for this work allows for robust page-flipping support and to synchronize flips on multiple hardware scan-out engines. With these patches, the drm_flip for atomic page-flipping is just implemented for the Intel DRM driver but not any of the other DRM kernel drivers. The work has been in an active development state for several months.

Related to the atomic mode-setting is nuclear page-flipping.
