[Qemu-devel] adding a new PCI device support in QEMU
Hi, I have a special kind of PCI device on my system. I want QEMU to emulate that device and have Guest VM see that. Can someone point me to any documentation available on how I/O device handling is done in QEMU? Thanks, Vinod Never miss a thing. Make Yahoo your home page. http://www.yahoo.com/r/hs

[Qemu-devel] [PATCH] (resend) Allow setting the vendor and model_id strings with x86's -cpu option
Would you consider the following patch, that allows users to set two
important x86 cpu options from the command line? (the vendor and
model_id strings)
Regards,
Dan.

[Qemu-devel] [PATCH] Rearm timer more often
The timer must be rearmed if a new timeout is added at the start of
the timeout list (or the new timeout will be expired too late.)
However, as the rearming always happens after servicing expired
timers, do not rearm in that case.
Also, move the setting of the dirty flag outside conditional in
host_alarm_handler(), to make sure it is always done. This broke kvm.
Cheers,
Anders.
