Bug ID: 103562 Summary: QXL driver disables IRQ and locks up when starting multihead weston, kernel 4.13 Product: DRI Version: XOrg git Hardware: Other OS: All Status: NEW Severity: normal Priority: medium Component: DRM/other Assignee: dri-devel@lists.freedesktop.org Reporter: vliaskovitis@suse.com
Kernel 4.13.9 Weston 3.0.0-1.1
The qxl driver has its IRQ disabled (and the screen locks up not suprisingly) when trying to start weston on a VM with dual-head qxl setup. Video card config of vm:
<video> <model type='qxl' ram='65536' vram='65536' vgamem='16384' heads='2' primary='yes'/> <address type='pci' domain='0x0000' bus='0x00' slot='0x02' function='0x0'/> </video>
Same dual-head setup works for gnome-shell/mutter though. So I am not sure if DRI/drm is the correct product/component.
These are the kernel messages seen when weston is started:
