Does the latest version build fine against Wheezy’s X.Org dev libs?

I was able to build source package v 0.1.1 from testing (apt-get -t testing source xserver-xorg-video-qxl) using libraries from stable (apt-get build-dep xserver-xorg-video-qxl) after installing one extra package: apt-get -t testing install libspice-protocol-dev.

Resulting module qxl_drv.so loaded fine in xorg from stable and performance has improved.

After further testing there appears to be a large amount of “Out of surfaces” messages in Xorg.0.log as well as OOM errors and “Out of video memory” messages. This is accompanied with several video artifacts.

I remember seeing this at least on Tails/Squeeze, and probably on Tails/Wheezy too.

Can you see that:

• with the newer QXL driver?
• with 64MB of video RAM assigned to the guest?

Ping?

1) 64 MB video ram does not really change anything since the initial testing (with video artifacts and ‘out of memory …’) was done on 64 MB memory anyway

2) attempting to build the latest qxl video driver (tag 0.1.3 from official git) against wheezy build-deps and wheezy-backports libspice-protocol-dev results in a loadable .so that seems to work with better performance but still has very nasty bugs in Xorg.log

3) same for 0.1.2

Great, thanks!

Two more questions, then:

• Have you tried building Jessie’s QXL driver (0.1.1-2) against wheezy+backports?
• Would you be willing to provide a wheezy-backports branch forked off the tag corresponding to the Wheezy version on git://git.debian.org/git/pkg-xorg/driver/xserver-xorg-video-qxl, or should I try and find someone else to take care of this part?

It builds but loading the resulting .so results in leaking memory on the order of 2GB per 5 seconds … :(

I am sorry, I do not know how to do this.
