GPU hang when switching video fullscreen

I use mpv with libva-intel-driver-g45-h264 (AUR) to watch videos. Today, I updated my system after a month and now video freezes if I go fullscreen. I get the following error on terminal:

intel_do_flush_locked failed: Input/output errord: 47

I tried downgrading a few packages like mpv, ffmpeg, sdl2, xorg-server and xorg-server-common, but that didn't help. I also installed/uninstalled xf86-video-intel with sna/uxa settings, rebooted computer several times, nothing worked.

GPU hang occurs only when I try to use hardware acceleration for fullscreen video playback im mpv. Non-fullscreen video works without issues. Any idea how this issue can be solved?

Re: GPU hang when switching video fullscreen

https://bbs.archlinux.org/viewtopic.php?id=230115 ? Although your dmesg does contain mention that IOMMU is being disabled for the chipset, it might still be involved in some way.

Re: GPU hang when switching video fullscreen

I tried "intel_iommu=off" in kernel parameters, didn't help!

$ cat /proc/cmdline

Re: GPU hang when switching video fullscreen

Ruling out the obvious: Did you rebuild ibva-intel-driver-g45-h264 after the system upgrade?

Re: GPU hang when switching video fullscreen

Yes, I remember installing it with pacaur, but just to be sure I uninstalled it just now, rebuilt after deleting cache, but the issue remains.
Meanwhile, I also tried vlc to rule out media player specific issue. VLC hangs up immediately before going fullscreen.

Yes, intel-ucode is installed from a long time and enabled in GRUB.

Re: GPU hang when switching video fullscreen

Just wondered because the revision is from 2010 (as is your BIOS, so...)

Tried the lts kernel?

Re: GPU hang when switching video fullscreen

Yes, this machine is 10 years old. Manufacturer doesn't provide updates anymore.

Tried LTS kernel, rebuild libva driver - the same. Enabling/disabling xfwm compositor also didn't make any difference.

Re: GPU hang when switching video fullscreen

pass "i915.error_capture=true i915.semaphores=1" to the kernel, this should get you an error dump in /sys/class/drm/card<N>/error where you can dump it and the semaphores *might* actually work around this.

Did you also try the lts kernel against xf86-video-intel (in case this has been your "good" setup before)

Re: GPU hang when switching video fullscreen

The dump is actually empty and GPU still hangs.

[  576.081062] [drm] GPU crash dump saved to /sys/class/drm/card0/error
$ ls -l /sys/class/drm/card0/error 
-rw------- 1 root root 0 Oct  9 19:24 /sys/class/drm/card0/error

I installed xf86-video-intel. It didn't fix the GPU crash, but now thumbnails on quickdial are correctly generated in my browser smile I'll keep it!

Re: GPU hang when switching video fullscreen

Desperate last call: "i915.enable_rc6=0 i915.enable_dc=0"

Edit: whatever you test - as long as you test on 4.13, use "intel_iommu=off" to prevent it from tainting the results.

Nope!

I think I'll have to use Arch Time Machine to go back in time and see when the problem first appeared.

Re: GPU hang when switching video fullscreen

So, it's mesa. On 10th Sep, mesa was upgraded from 17.1.8-2 to 17.2.0-2 which breaks video functionality.
Video works perfectly on 9th Sep, and breaks on 10th; keeping my system on 10th and downgrading mesa fixes the video problem. This is the excerpt from pacman.log for the "faulty" upgrade:

[2017-10-10 20:49] [PACMAN] Running 'pacman -Syyuu'

So, how do I go about this? Should I keep mesa at the "good" version and update rest of the system? But then this partial upgrade may cause other surprises. Any recommendations?

Re: GPU hang when switching video fullscreen

What happens if you revert only the patch? And yes, you should file a bug. This looks critical and only older IGPs are affected.

Re: GPU hang when switching video fullscreen

The conflict file looks fishy (there's a stray bitmask clearance) but the relevant part should be to turn

   if (mask & BUFFER_BITS_COLOR) {
      brw_blorp_clear_color(brw, fb, mask, partial_clear,
                            ctx->Color.sRGBEnabled);
      debug_mask("blorp color", mask & BUFFER_BITS_COLOR);
      mask &= ~BUFFER_BITS_COLOR;
   }

into

   if (devinfo->gen >= 6 && (mask & BUFFER_BITS_COLOR)) {
      brw_blorp_clear_color(brw, fb, mask, partial_clear,
                            ctx->Color.sRGBEnabled);
      debug_mask("blorp color", mask & BUFFER_BITS_COLOR);
      mask &= ~BUFFER_BITS_COLOR;
   }

around line 296 (ie. follow the BUFFER_BITS_DEPTH_STENCIL pattern right below)

Re: GPU hang when switching video fullscreen

Adding 'brw->gen >=6' back to the condition fixes the issue. Verified with 17.2.4 patched and built.
Bug report: https://bugs.freedesktop.org/show_bug.cgi?id=103529

Thanks seth for all the help!
