            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 suprisingl=
y)
when trying to start weston on a VM with dual-head qxl setup. Video card co=
nfig
of vm:

<video>
  <model type=3D'qxl' ram=3D'65536' vram=3D'65536' vgamem=3D'16384' heads=
=3D'2'
primary=3D'yes'/>
  <address type=3D'pci' domain=3D'0x0000' bus=3D'0x00' slot=3D'0x02' functi=
on=3D'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:

Same dual-head setup works for gnome-shell/mutter though. So I am not sure =

DRI/drm is the correct product/component.

These are the kernel messages seen when weston is started:
