The only difference to hardware revision 4 is that the device doesn't
switch to VGA mode in case someone happens to touch a VGA register,
which should make things more robust in configurations with multiple
vga devices.

Swtiching back to VGA mode happens on reset, either full machine
reset or qxl device reset (QXL_IO_RESET ioport command).

this patch -- commit ed71c09ffd6f -- disables ACPI S3 in the Windows 10
guest for me, using OVMF and QXL.

The "Sleep" menu entry disappears from the power button icon/menu at the
login screen, and "psshutdown -d -t 3" (from the pstools package) also
stops working (it reports that the computer does not support S3).

At the parent commit (e18e5501d8ac), S3 suspend/resume works.

Here's the bisection log:

OVMF is built at current edk2 master: e63d54db9526.

In the Windows 10 guest, the installed driver has the following
properties (per Device Manager):

- driver date: 7/28/2015
- driver version: 22.33.46.473

I tried upgrading the QXL driver in the Windows 10 guest, using the
latest package at
<https://fedorapeople.org/groups/virt/virtio-win/repo/latest/?C=M;O=D>,
namely "virtio-win-0.1.173-7.noarch.rpm". But Device Manager said that
the currently installed driver was already the best / most recent for
the device.

For now I'll force the revision back to 4 using <qemu:arg> elements in
my domain XML. (I'd like to use pc-q35-5.0.)

    <qemu:arg value='-global'/>
    <qemu:arg value='qxl-vga.revision=4'/>

Thanks
Laszlo

This is not what I would expect from any qxl driver for Win10 
What is the name of display adapter? 
The driver provider is 'Red Hat'? 
Does your guest run with secure boot? 
I do not see such an effect with 'Sleep' with latest qemu master + OVMF + qxl + Win10, the sleep button does not disappear.

Any chance the qxl windows guest driver checks "revision == 4"
instead of "revision >= 4"?

cheers,

Not with qxl-wddm-dod drivers I'm releasing. 
But driver attributes that Laszlo provided are not related to any driver I'm aware of.

"Red Hat QXL controller"

> The driver provider is 'Red Hat'?

In the "Red Hat QXL controller Properties" dialog:

- on the General tab, Manufacturer is "Red Hat, Inc."

- on the Driver tab, both the "Driver Provider" and the "Digital Signer"
  fields are "Red Hat, Inc."

This driver comes from "qxlwddm-0.1-12" (buildID=449635), in Brew.

In retrospect it looks like this driver was meant for Windows 8 only,
but it happened to install under, and work OK for, Windows 10 too.

> Does your guest run with secure boot?

Yes, it does. (Double-checked it with "confirm-SecureBootUEFI" in
PowerShell.)

I'm happy to try other driver versions. Hopefully Windows 10 will
actually see them as upgrading the currently installed driver. (Or
should I uninstall first?)

Thanks!
Laszlo

"spice-qxl-wddm-dod-0.19-8.1-compatible.zip" solved the issue in my
Windows 8.1 and Windows Server 2012 R2 guests.

"spice-qxl-wddm-dod-0.19.zip" solved the issue in my Windows 10 guest.

The driver updates were painless.

Thanks!
Laszlo
