Hello, This patch series contains two completely unrelated features that just happen to have been developed one right after the other. Patches 1/5 to 3/5 implement explicit fences support. The first patch fixes event handling in the omapdrm driver as required by the atomic commit helper (and the DRM atomic update API). The second patch replace the hand-rolled atomic commit handler with the DRM core atomic commit helper, bringing fences support as a bonus. The third patch then removes the omapdrm custom sync support that has no user in the mainline kernel. Patches 4/5 and 5/5 clean up zpos handling by switching to the standard zpos property implemented in the DRM core. The omapdrm-specific zorder property is kept for backward compatibility as an alias and should be removed later after a long enough grace period for userspace to be updated. Compared to v1, the patches have been rebased on top of Dave's drm-next branch which now contains all the dependencies. On the testing side, I've ran kmstest --flip for 250 frames in a loop for half an hour, with and without CPU load (with 'stress -c 4'), on both PandaBoard and AM572x EVM, and couldn't reproduce any of the issues reported against v1. As fence support is implemented completely inside the atomic commit helper I have only tested it lightly using the sw-sync driver. No issue has been noticed.
