Hi Daniel, I tested your branch " wip/2017-09/atomic-v12" on Intel Apollo Lake with: - Linux Kernel v4.9 - Libdrm 2.4.83 - Mesa 13.0.6
In the end, I could not test the atomic modesetting with this setup. I got this warning "DRM: does not support atomic modesetting". When I checked the source code, I saw that atomic modesetting depends on DRM_CAP_CRTC_IN_VBLANK_EVENT, which is introduced to the kernel with this commit "5db06a8a98f515f67446a69c57577c4c363ec65d" in 4.12 Linux kernel. I also saw a regression. After desktop-shell sets the display black, weston crashed with this callstack: Oct 04 02:25:39 gr-mrb-64 weston[1922]: weston: ../../../../../../../../weston/libweston/compositor.c:2474: weston_output_finish_frame: Assertion `output->repaint_status == REPAINT_AWAITING_COMPLETION' fa iled.
