This patch set adds support for dynamic resolution changes with the WDDM
driver on Windows >= 8. It is based on the one sent by Vadim Rozenfeld
with some improvements:
- It detects both the XDDM driver and the WDDM driver, and uses the
correct API.
- It detects if the client is trying to set the same resolution again,
and does nothing. This is the result of the client detecting a primary
surface destruction/construction when the resolution changes, and
asking for a resolution change again. This bug does not happen with
the XDDM driver, so it may be avoidable in some other way.
- It uses an alternative method to update the list of display modes,
that results in a nicer effect when changing the resolution. This
method is compatible with the current driver implementation (v0.12),
but for best results we have modified the driver to drop the previous
method and to improve support of hardware pointers. The source can be
found in https://github.com/flexvdi/qxl-dod, and precompiled and signed
binaries can be downloaded from http://depot.flexvdi.com/guest-tools/.
Big thanks for help improving windows>=8 support (unfortunately still
overlooked).
I want do a fast test to see is your changes solve the bugs (and/or
occasional hangs) I have found trying spice-guest-tools 0.100 and
qxlwddm-0.12.zip on windows 10 guests. For tests your improvements I can
simply install spice-guest-tools.exe inside
flexvdi-guest-tools-2.2.3.exe and qxlwddm-0.13-flexvdi.zip?
You can just install spice-guest-tools.exe, as it includes both
the patched vdagent.exe and the new driver.
Actually, I suspect you will have tu uninstall the previous driver
first, as I forgot to increase the version number and Windows will
probably say that the driver is already up to date.
Thanks, I did some fast tests with them.
The resolution change seems better, I tried all possible cases and
now worked correctly always.
The mouse seems better, mainly in case of high load when before was
near unusable.
About the occasional windows freeze I don't know if is solved, for
now with your build wasn't happen.
I not found any regression.
I
have enough knowledge to review the code, can
someone review it for upstream please?
Thanks for any reply and sorry for my bad english.

Detect and use the new WDDM driver
Use CCD API to update the WDDM display modes.
