[Xen-devel] Re: pvusb drivers for pvops 2.6.32.x kernel

[Pasi Kärkkäinen <pasik@xxxxxx>]

Hello,

Jeremy: See the included patch. If it's OK it'd be nice
to get it into xen/stable-2.6.32.x branch.

Thanks Nathanael!

I've attached an updated diff against the pvops xen/stable-2.6.32.x tree.
I've tested by attaching an af9015 USB TV tuner to a pvops domu from
a pvops dom0 and recording a few hours of TV.

I also tried to attach various USB devices to a WinXP domu with GPLPV
drivers, but the domu kept crashing. That needs more investigation, but
I suspect a problem with the GPLPV drivers. I'm keen for that to be fixed,
but I don't have time immediately to dig into it.

I took a look at the patches at
http://gitorious.org/opensuse/kernel-source/trees/SLE11-SP1/patches.xen
and as far as I can tell, everything that relates to pvusb is included in the
attached patch.

Nathanael
