Hi,

Hi Jan. HPET is not in qemu-kvm yet because there are some issues unique

This patch is based on the recent patch from Vincent Minet. I split
Vincent's
changes into 2 patches (to separate MADT and RSDT table cleanup, as
suggested by
Marcelo) and added a bit to them. And to give credit where it is due,
this
cleanup is also re
I have decided to take a job outside of IBM and so will not be involved
with HPET any longer. Working on KVM has been great fun... top-notch
people and a top-notch technology. Wishing KVM and you all the best!

I still found the emulated HPET would result in some boot failure. For
example, on my 2.6.30, with HPET enabled, the kernel would fail

I pulled the latest:
kvm (commit 3c260758b41000986c3c064b17a9771286e98d1e)
kvm-userspace (commit 6892f63c18a526c7b54bbde2f59287787eabe1f8)
and built and installed the 2.6.28-rc7 x86_64 kernel from kvm pull, then
tried to build kvm-userspace and the build failed:
make -C /lib/modules/2.6.28-rc7
I discovered a bug in the hpet code that caused Windows to boot without
hpet. The config mask I was using was preventing the guest from placing
the hpet into 32 bit mode.

disabling of 8254 and RTC timer interrupts when operating in legacy
mode. The HPET spec says "in this case the 8254/RTC timer will not cause
any interrupts". I'm not sure if I should disable the RTC/8254 in some
more general way, or just disable interrupts. Comments appreciated.
This patch, written by Ryan Harper, adds HPET support to BIOS.

But in any case, I didn't see the 10ms wakeup cycle with CONFIG_NO_HZ.
If anyone can shed any light on this, I could look into it more if need
