Here's a bunch of new stuff on top of my last atomic modeset/pageflip posting.
Highlights: - some bug fixes - started moving common property bits out of intel_atomic.c - hooked up the properties to some legacy code paths - non-blocking GPU synchronization
The GPU sync part could surely use some experienced peoples' attention. I didn't spend too much time on it, but based on some initial testing it seems to be working. Haven't stressed it that much though.
Oh and in patch 22 I left the default to blocking GPU sync, so if you want to try it, you actually have to go and poke /sys/module/drm/parameters/async_gpu to make it use the non-blocking sync code.
As usual my git repo has all the goods: https://gitorious.org/vsyrjala/linux/commits/drm_atomic_19
No changes to libdrm since the last time. Code is still here: https://gitorious.org/vsyrjala/drm/commits/drm_atomic_7
I also pushed a reasonably clean test app. It uses gbm to manage the buffers and GLES2 to render funky triangles. You can get it here: https://gitorious.org/vsyrjala/glplane
