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/.
You might be interested in taking a look at Sandy's work recently pushed
to freedesktop at
https://cgit.freedesktop.org/~teuf/qxl-wddm-dod/
and thank you for your work on this,

Thank you, Victor. I'll see if these patches are in sync with her
job.
It turns out they are not. In particular, she changed the interface
to send a custom resolution to the driver. I'm going to try to
coordinate with her, in case she also has a patch set for the
vdagent, so do not push these patches upstream yet.
Thanks for pointint this out.
Changes from v1:
- New types and classes have been moved from common/vdcommon.h to
vdagent/wddm.h, since they are actually not common to both the vdagent
and the vdservice. The code for those classes is in vdagent/wddm.cpp.
- Some improvements as suggested by Frediano Ziglio.
Javier Celaya (2):
Detect and use the new WDDM driver
Use CCD API to update the WDDM display modes.
