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 two parts:
1-12: cleanups to the core kernel, either to fix outright problems,
or to add appropriate hooks needed by Xen
13-24: the Xen guest 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 2.6.20-git16.
Changes since the previous posting:
- rebased
- xen-console has been replaced with a xen backend for the hvc console
- dropped patch to remove pgd ctor/dtor
- shared-kernel-pmd extensively reviewed by wli
- use vmalloc_sync_all in alloc_vm_area
- cleaned up Xen Kconfig stuff
I looked at linking in xen-head.S rather than including it into
xen-head.S, but it seems to provoke linker bugs, so I've left it as-is
for now.
Thanks,
J
