[patch] Initialize xen_vcpu0 before initialize irq_ops
Hello,
I find a strange behavior. When a machine is slow (or with many debug
traces or a qemu vm),
a interrupt can occur between the pv_irq_ops initialization and the xen_vcpu[0]
initialization. This lead to a problem because some operations in
xen_irq_ops use
xen_vcpu.
I send you a patch to fix that but I''m not quite sure that is the
right solution.
Regards,
Anthoine

[PATCH 04/10] x86/paravirt: use a single ops structure
Instead of using six globally visible paravirt ops structures combine
them in a single structure, keeping the original structures as
sub-structures.
This avoids the need to assemble struct paravirt_patch_template at
runtime on the stack each time apply_paravirt() is being called (i.e.
when loading a module).

[PATCH 00/10] paravirt: make amount of paravirtualization configurable
Today paravirtualization is a all-or-nothing game: either a kernel is
compiled with no paravirtualization support at all, or it is supporting
paravirtualized environments like Xen pv-guests or lguest additionally
to some paravirtualized tuning for KVM, Hyperv, VMWare or Xen
HVM-guests.
As support of pv-guests requires quite intrusive pv-hooks (e.g. all

[PATCH 00/10] x86/paravirt: several cleanups
This series removes some no longer needed stuff from paravirt
infrastructure and puts large quantities of paravirt ops under a new
config option PARAVIRT_XXL which is selected by XEN_PV only.
A pvops kernel without XEN_PV being configured is about 2.5% smaller
with this series applied.

[PATCH RFC] paravirt_ops: refactor struct paravirt_ops into smaller pv_*_ops
This patch refactors the paravirt_ops structure into groups of
functionally related ops:
pv_info - random info, rather than function entrypoints
pv_init_ops - functions used at boot time (some for module_init too)
pv_misc_ops - lazy mode, which didn't fit well anywhere else
pv_time_ops - time-related functions
pv_cpu_ops - various privileged instruction ops

[PATCH 00/12] xen/paravirt_ops patches for 2.6.24
Hi Linus,
Here's a set of patches to update paravirt_ops and Xen for 2.6.24
A quick overview of the patchset:
paravirt_ops:
Remove the monolithic paravirt_ops structure, and replace it with
smaller structures of related functions. Also, clean up the handling
of lazy mode to make it easier to implement.

[PATCH RFC] first cut at splitting up paravirt_ops
Here's a first attempt at splitting up paravirt_ops into more specific
chunks. Its pretty clunky and chunky; mostly just a lot of
replacement. The grouping of ops is very first cut; I'm open to
suggestions about what groups should exist and what ops they each should
contain.
The only slightly subtle part is that I've kept the structures wrapped
in a paravirt_ops structure,

[PATCH 0/15] adjust pvops to accomodate its x86_64 variant
Hi folks,
With this series, the bulk of the work of pvops64 is done.
Here, I integrate most of the paravirt.c and paravirt.h files, making
them applicable to both architectures.
CONFIG_PARAVIRT is _not_ present yet. Basically, this code is missing page
table integration (patches currently being worked on by Jeremy).
Enjoy
