[Bug 320813] Re: [drm] compiz animations cause temporary freezes with vblank
The third patch does improve things on Gigabyte GA-EG45M-DS2H mobo (G45), I can suspend/resume and VT switch without getting into that annoying 1sec freeze mode. I have not yet tried running xorg for a _long_ time to see if that still triggers the bug. glxgears now also reports around 60 FPS as excepted with vblank (the gears move now but they still flicker in a very annoying way, I guess this is a separate bug though). I can play chromnium arcade with nice FPS etc. With 3-4 windows on each cube side the overall graphics performance is still _horrible_ when spinning the cube though. It doesn't stop for 1sec but it's embarrassingly slow for a quad core 2.8ghz, 8GB machine. If I _hold_ the spin cube to the right button for about 10-15 seconds then audio from totem is more or less certain to skip (silence for about 1sec) which is really annoying because it happens also sometimes on single normal ALT-TAB (not every ALT-TAB though). G45 definitely needs some more love before it's usable.

Yesterday before I went to sleep I rebooted by G45 machine and when left it running over night with both of the drm patches applied.

Another scary note is that I now currently see this on the G45 machine (I used to have around 60 FPS in glxgears before I applied the drm patches because of the slow down to screen Hz but now it's getting crazy... basically I can't even see the gears moving at all and the FPS is single digit): mn...@kingfish:~$ glxgears 49 frames in 5.1 seconds = 9.528 FPS 20 frames in 10.2 seconds = 1.957 FPS 20 frames in 10.2 seconds = 1.960 FPS 20 frames in 9.2 seconds = 2.170 FPS (Note: that's 2 frames per second, and not 2000 FPS!!) -- [drm] compiz animations cause temporary freezes with vblank https://bugs.launchpad.net/bugs/320813 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Subject: [PATCH] capture last_vblank count at IRQ uninstall time too
In dc1336ff4fe08ae7cfe8301bfd7f0b2cfd31d20a (set vblank enable flag correctly
across IRQ uninstall), we made sure drivers that uninstall their interrupt
handler set the vblank enabled flag correctly, so that when interrupts are
re-enabled, vblank interrupts counts work as expected. However I missed the
last_vblank field: it needs to be updated as well, otherwise, at the next
drm_update_vblank_count we'll end up comparing a current count to a stale
one (the last one captured by the disable function), which may trigger the
wraparound handling, leading to a jumpy counter and hangs in drm_wait_vblank.
The jumpy counter can prevent the DRM_WAIT_ON from returning success if the
difference between the current count and the requested count is greater than
2^23, leading to timeouts or hangs, if the ioctl is restarted in a loop (as
is the case in libdrm 2.4.4).

[Bug 320813] Re: [drm] compiz animations cause temporary freezes with vblank
Timo, I read through that thread on dri-devel, and would like to add, just for the record, that for me the problem was never related to VT switching or suspend/resume cycles. The freezes start occuring after a few minutes of normal usage. I don't know if this is relevant, but thought I'd mention it. -- [drm] compiz animations cause temporary freezes with vblank https://bugs.launchpad.net/bugs/320813 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 320813] Re: [drm] compiz animations cause temporary freezes with vblank
The DRI settings workaround eliminates the random stops. But I have a feeling that it ran more smoothly in Intrepid, now it looks like ~2-4 fps with zoom taking about 2 seconds, if I have more than about 10 windows on a workspace. Or maybe I just have more windows open now, anyone else notice a slowdown? -- [drm] compiz animations cause temporary freezes with vblank https://bugs.launchpad.net/bugs/320813 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 320813] Re: [drm] compiz animations cause temporary freezes with vblank
For the record, I can perfectly reproduce this after suspend when using EXA (GMA945). I have used UXA since today, and with that suspend/resume with compiz works fine, i. e. this bug doesn't hit me with UXA. As requested by Steve, I'll put this onto the release radar. ** Tags added: regression-potential -- [drm] compiz animations cause temporary freezes with vblank https://bugs.launchpad.net/bugs/320813 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 320813] Re: [drm] compiz animations cause temporary freezes with vblank
Timo, can you attach the kernel patch here? ** Changed in: linux (Ubuntu) Target: None = jaunty-alpha-6 ** Changed in: linux (Ubuntu) Assignee: (unassigned) = Tim Gardner (timg-tpi) ** Description changed: Some compiz animations (most, though not all) cause temporary freezes. For example, when spinning the cube or switching between applications, everything on the screen suddenly freezes for a couple of seconds, and then it returns to normal. The desktop behaves sort of like a narcoleptic person would. Normally, this behavior starts a couple of minutes after X has started. That is, when logging in to a GNOME session, everything is smooth and fine for a couple of minutes, and then this problem surfaces making compiz unusable. Furthermore, the problem only appears when using EXA. With UXA this particular problem does not appear. Unfortunately, I haven't found anything of interest in the logs and don't know where else from to get additional useful information. Please let me know how I can help. Xorg.0.log attached. This is on Jaunty with the following packages. libdrm: 2.4.4-0ubuntu2 libgl1-mesa-dri: 7.3~rc3-1ubuntu1 xserver-xorg-video-intel: 2:2.6.1-1ubuntu1 linux-image-2.6.28-5: 2.6.28-5.15 I reported the upstream bug as well, but with packages I had compiled myself for intrepid.

actually, there's another proposed patch now, since the one I forwarded is 'only a workaround to hide the real bug'.
