I'm using the Unichrome driver with XFree86 4.5.0 and I'm hitting

I sent the previous message to fast and did not reply to you question
correctly.
The problem in the current CVS unichrome driver is a Opss when the via_drv.o
deallocates a piece of DRM memory twice. Elsewhere in the Xserver DRM
context
1 is removed. (This occurs when the Xserver resets its self when the lat
client
disconnects and the a new client connects and uses XVIDEO). It would
appear that
the via_drv.o code needs to be called back to tell it to shutdown. Is
there such a
call back to a driver? If so the via_drv.o code needs to arrnage for it
to be called
and clean up.
The via driver (X server) is supposed to take care of closing down and
cleaning up everything it has used when its CloseScreen function is
called. I don't know if you're seeing a bug in the X driver or the
kernel driver. Server reset is often a poorly tested case, but it is
usually straightforward to fix the problems that arise there.
O.k. I hunt for the CloseScreen function.
I'm about to ship a product with a work around to the bug in the
Unichrome drivers.
I'm not going to be able to doing any testing until a few weeks time.
What I really need to know is do you have people that are supporting
UNichrome for
XFree86. I can work with them on getting the bugs fixed. However if
unichrome
does not have support then I going to be forced to Xorg that does have
support, and
I'm not happy with the stability of Xorg.
I'm not aware of anyone specifically working on the via driver for XFree86.
Why not take it on yourself?
I'm contributing patches to the Unichrome project. If you integrate
their code into
XFree86 periodically then you will be in better shape then what shipped
in 4.5.0.
I get to spend time on these drivers only when they break, its part of
my day job.
I cannot commit time in an ongoing basis.
I suggest you contact Luc Verhaegen of the Unichrome project for on
going support.
