Subject: qxl: clear irq on reset
X-Git-Url: https://repo.jachan.dev/qemu.git/commitdiff_plain/f06b85218a41fd6f8e797a925f4ea75640b69c9e

qxl: clear irq on reset

Without this we occasionally trigger an assert at
hw/pci/pci.c:pcibus_reset that asserts the irq_count is zero on reset.

This has become a problem with the new drm driver for linux, since doing
a reboot from console causes a race between console updates that set the
irq and the reset assertion that the irq is clear.
