Hi All,
As some of you know I've been working on a prototype for
a Linux agent.
I've most of the framework in place. Currently it does
not do anything but client mouse mode, but adding more
stuff should be relatively easy.
You can grab it here:
http://cgit.freedesktop.org/~jwrdegoede/vdagent-linux/
A simple "make" will give you a vdagentd and a vdagent, start
vdagentd as root, chmod 666 /tmp/vdagent (to be fixed) and
then start vdagent from your x11 session.
I used kraxels evdev userspace (uinput) device using agent
prototype as a basis for this.
The biggest difference is the addition of a separate process
to run in the xorg session (and communication between the 2).
With the current code this separate vdagent process notifies
the vdagentd of the x11 root window size, so that it can
adjust the uinput device's dimensions to match, this removes
the need for telling vdagentd the size manually, and makes
vdagentd automatically adjust the uinput device for xserver
resolution changes.
p.s.
Note that due to a kernel bug, unless you patch your kernel
vdagentd can get behind with mouse agent message processing,
this is caused by select on the virtio port blocking even
though there is data to be read, see:
http://lists.freedesktop.org/archives/spice-devel/2010-September/001151.html
For details and a patch fixing this. I've already added this
patch to the F-14 kernels, so the next F-14 kernel build
won't have this issue.
Regards,
Hans
