[Spice-devel] [PATCH qxl-win v3] miniport+display: export FLUSH_{SURFACES, RELEASE} ports for use by AssertModeEnable

[Alon Levy]

Revision 3 (V10) of the qxl device supports these added io ports which make sleep, resolution
change and logout simpler to implement with less vmexits from pov of the driver.
