Description Marian Krcmarik 2011-04-28 10:01:13 UTC

Description of problem:
When switching youtube video to full-screen mode Xorg does crash because of running out of memory drawing images.
If I do increase available memory using qemu switch -global qxl-vga.vram_size=268435456 then I am able to switch to full-screen without the crash, that's why I believe we should increase default amount of memory available to qxl device, which is known issue. This bug hopefully pushes it forward.

Version-Release number of selected component (if applicable):
spice-client-0.8.0-2.el6.x86_64
spice-protocol-0.8.0-1.el6.noarch
spice-server-0.8.0-1.el6.x86_6
xorg-x11-drv-qxl-0.0.12-9.el6
qemu-kvm-0.12.1.2-2.159.el6.x86_64

How reproducible:
always

Steps to Reproduce:
1. Run qemu instance with spice support and RHEL guest with qxl device installed and used.
2. Open youtube website and try to open any video in full-screen mode.
  
Actual results:
Xorg's crash:
Out of memory allocating 8294420 bytes
Out of mem - stats

Expected results:
No crash, video in full-screen

Additional info:
Increase vram size with adding option to qemu instance i.e. -global qxl-vga.vram_size=268435456 when using one qxl device and no crash appears.

Thanks for the bug report.  We have reviewed the information you have provided above, and there is some additional information we require that will be helpful in our diagnosis of this issue.

Please add drm.debug=0x04 to the kernel command line, restart computer, and attach

* your X server config file (/etc/X11/xorg.conf, if available),
* X server log file (/var/log/Xorg.*.log)
* output of the dmesg command, and
* system log (/var/log/messages)

to the bug report as individual uncompressed file attachments using the bugzilla file attachment link above.

We will review this issue again once you've had a chance to attach this information.

Thanks in advance.

Comment 7 Marian Krcmarik 2011-07-05 11:10:23 UTC

It does not happen with older qxl - xorg-x11-drv-qxl-0.0.12-2.1 -> marking as regression.

Comment 9 Søren Sandmann Pedersen 2011-07-27 17:56:57 UTC

Devel ack, though it would be useful to also open a bug against libvirt to make it set vram to 256MB by default.
