Nuclear Page-Flipping For Linux GPU DRM

Inspired by the atomic mode-setting work of Intel, Rob Clark of Texas Instruments is seeking comments on his new nuclear page-flipping implementation for the Linux kernel DRM sub-system.

Rob Clark says on the dri-devel mailing list, "This is following a bit the approach that Ville is taking for atomic-modeset, in that it is switching over to using properties for everything. The advantage of this approach is that it makes it easier to add new attributes to set as part of a page-flip (and even opens the option to add new object types)."

At the moment he has only updated the Texas Instruments OMAPDRM driver as a proof-of-concept implementation. The code can be found from his drm_nuclear repository that makes over 1,300 lines of code changes.
