Atomic Page-Flipping Still Being Worked On

For those wondering about the state of atomic mode-setting / page-flipping, it's still being tackled by an Intel developer.

Ville Syrjala of Intel OTC re-published his patches today when it comes to the atomic page-flipping support. "I'm posting this as rather raw just to get a bit more substance to the discussions."

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.

Meanwhile, Rob Clark of Texas Instruments recently began working on a nuclear page-flipping design.
