[PATCH 0/2 v05] lguest: TSC & hrtimers
The following patches are the latest update of the TSC and hrtimer patches
I posted on 29/03.
Rusty's original TSC patch has been resynced to the latest lguest repo,
as has the hrtimer patch, which also incorporates feedback from Jeremy &
Rusty:
- Change clock event hrtimer to absolute time. 'now' is captured in the
host during the hypercall.
- Propagate -ETIME back to the

[PATCH RFC v3 0/6] x86/idle: add halt poll support
From: Yang Zhang <yang.zhang.wz at gmail.com>
Some latency-intensive workload have seen obviously performance
drop when running inside VM. The main reason is that the overhead
is amplified when running inside VM. The most cost I have seen is
inside idle path.
This patch introduces a new mechanism to poll for a while before
entering idle state. If schedule is needed during poll, then we

[PATCH 0/7] Modify lguest32 to make room for lguest64
Hi all,
I've been working on lguest64 and in order to do this, I had to move
a lot of the i386 specific out of the way. Well, the lguest64 port
is still not ready to display, but before Rusty makes too many changes
I would like this in upstream so I don't have to keep repeating my
changes :-)
So this patch series moves lguest32 out of the way for other archs.

[RFC PATCH v6 00/92] VM introspection
The KVM introspection subsystem provides a facility for applications running
on the host or in a separate VM, to control the execution of other VM-s
(pause, resume, shutdown), query the state of the vCPUs (GPRs, MSRs etc.),
alter the page access bits in the shadow page tables (only for the hardware
backed ones, eg. Intel's EPT) and receive notifications when events of
interest have taken place
