Hi Andi,
This patch series implements the Linux Xen guest as a paravirt_ops
backend. The features in implemented this patch series are:
* domU only
* UP only (most code is SMP-safe, but there's no way to create a new vcpu)
* writable pagetables, with late pinning/early unpinning
(no shadow pagetable support)
* supports both PAE and non-PAE modes
* xen hvc console (console=hvc0)
* virtual block device (blockfront)
* virtual network device (netfront)
The patch series is in three parts:
1- 2 Cleanup patches to various parts of the kernel
3-14 Extensions to the core code and/or paravirt ops, needed to support
Xen. Includes hooks into get/setting pte values and the new
patching machinery.
15-26 The Xen paravirt_ops implementation itself.
(Some of the earlier patches in the series have already been posted,
but are included to make the series self-contained.)
I've tried to make each patch as self-explanatory as possible. The
series is based on 2.6.21-rc1.
Changes since the previous posting:
- implemented new patching scheme, which should make the overhead of
running on native approach zero, and Xen overhead a fair bit lower
- rebased
- some small review comment updates
- trailing whitespace stripped
- accurate diffstats
Thanks,
J
