weston version: 2.0.0 kernel version: Linux version 4.4.41 drm driver: support drm atomic. gpu verion: Mali-T860 OpenGL ES 3.2 v1.r13p0-00rel0 How to enable planes for atomic?
Hi, what do you mean and how is it a bug or a feature request? I mean, this question might have been more suited for the mailing list. Support for atomic modesetting has not yet been merged into Weston upstream: https://patchwork.freedesktop.org/series/20655/
Thanks Pekka! I have pulled Daniel Stone's code: git://git.collabora.com/git/user/daniels/weston#wip/2017-03/atomic-v9 But weston could not be started normally,the error log is: ......

This is implemented by storing the absolute time for the next repaint for each output locally, and maintaining a global timer which iterates all of them, scheduling the repaint for the first available time.

Really? That's interesting, as I am about to land that patch in Weston upstream real soon now. Does "unhandled level 3 translation fault (11) at 0x00000000" mean it segfaulted from dereferencing NULL? I'm not familiar with that message. Can you get a backtrace with gdb when you are exactly at the first problematic commit, please? Next time, please carefully explain the revision of weston you are running. It is not 2.0.0 because you have patches on top.
There is no segfaulted problem when I use Daniel Stone's code compile directly (git://git.collabora.com/git/user/daniels/weston#wip/2017-03/atomic-v9) . [08:54:13.052] weston 2.0.90 http://wayland.freedesktop.org Bug reports to: https://bugs.freedesktop.org/enter_bug.cgi?product=Wayland&component=weston&version=2.0.90 The weston version is 2.0.90, I test 4k Video performance can get 60fps. test_case = 1, display source=/mnt/3840x2160_nv12.bin Fps = 60.016 mFrameConut=31 now=1883330336 Fps = 59.998 mFrameConut=62 now=1883847016 Fps = 59.982 mFrameConut=93 now=1884363840 But this patchs lead to Wayland connection broke issue when HDMI hotplug?

I am a little confused. The patch is *in* the atomic-v9 branch you said works fine. Are you saying that the branch works fine as a whole otherwise, but hot-unplugging an output causes Weston to segfault? And you have bisected to confirm, that the segfault on hot-unplug starts happening on "Switch to global output repaint timer"? When you do the hot-unplug, are there no connected outputs left after that? I suspect it might be a crucial detail on whether at least one output still remains, or if there are none. Support for zero outputs is fairly young in Weston and probably not commonly tested. For me, testing hotplug behavior is always a pain. On a quick glance I don't see anything in that particular patch that would crash with zero outputs, so a backtrace of the crash would be helpful.

The atomic-v9 branch works fine as a whole otherwise, but weston works abnormally when HDMI connected and disconnected. I have added two error log files.Please see the attachment.

I'll fix that, but again, that's nothing to do with the global-repaint series itself; it only comes in with the patch to move the scanout plane to using a drm_plane. I haven't seen the crash on disconnect, mind. Hm. More hotplug testing required.

This could really use a gdb backtrace. What code exactly you ran to get this output? Which git sha1 from Daniel's branch? I could not reproduce this on a quick try. I did see "function is no-op" messages only during HDMI was disconnected, coming from Mesa src/mapi/table.c I believe.
(In reply to Pekka Paalanen from comment #11) > I did see "function is no-op" > messages only during HDMI was disconnected, coming from Mesa > src/mapi/table.c I believe. And that also happens without the patch, so a red herring.

What did you expect to happen? What was the actual result? Can you please try wip/2017-03/atomic-v10-WIP, and provide some more detailed comment?

Yes, those are available in the drm and kernel trees in the same place as my weston tree.
Much of the atomic patchset landed in 4.0, and there are newer versions for the rest on the list.
