This patch series implements a paravirtualization interface using:
- the device tree mechanism to pass hypervisor informations to the guest
- hypercalls for guest->host calls
- an example exploiter of that interface (magic page)
This is work in progress, but working so far. I just start to really exploit
the fuctionality behind the magic page mechanism therefor I can't provide any
performance improvements so far, but it is evolved enough for RFC and to start
the standardization discussion.
Are you aiming this for the current merge window, ie for 2.6.27?
The aim is not really fixed. It would be nice to get into 2.6.27, but
since I can't yet expect how long it takes ...
Actually the guest patches would already go through reviews and
upstream, due to the fact that the guest code changes are not that (the
major part of the implementation will go over kvmppc -> kvm upstream).
But since I want to discuss about the standardization on the embedded
hypervisor list first, the naming of the device tree entries are not
fixed yet.
Therefor I can't yet define which kernel version merge window I'll
target/reach.
btw - embedded hypervisor - I got advised that this is a closed list
which I forgot.
Sorry for all who got bounces on a replay-all action. The next version
of the patch series will go to the involved open source lists only and a
separate more standardization than patch style mail series to embedded
hypervisor.
