Question about xen/stable branch in kernel pv_ops

Question about xen/stable branch in kernel pv_ops

[Fantu]

I see new branch (xen/stable) in pv_ops based on 2.6.32.9, is good? for test
it there only to change xen/master in xen/stable in
buildconfig/mk.linux-2.6-pvops right?
I also see update in this page, for use config example for xen/stable i must
use "64bit x86_64 (xen/next 2.6.32)"?
Why is add CONFIG_XEN_PCIDEV_FRONTEND=y in page but there isn't in example
config?

Thanks advance for any reply

I don't know what's the status of xen/stable, I haven't tried it yet.
Maybe Jeremy can comment on that..

You can also clone/checkout and build it separately, no need to build it as 
part of Xen hypervisor.

I assume you're talking about XenParavirtOps wiki page.
I added CONFIG_XEN_PCIDEV_FRONTEND=y there yesterday based on Konrad's request,
but it seems I don't have it in my example .config files.

xen/stable seems to be xen/next plus merges up to v2.6.32.9 . I did a 
build based on it yesterday, and it seems to work the same as xen/next 
did.

Yeah, xen/stable is going to be the 'long term maintained' branch,
based on the long term maintained upstream 2.6.32.

That is my fault. I was hoping to have the PCI frontend branch ready by
the time Pasi would have added that in (and ask Jeremy to merge it in),
but I am still trying to narrow down the list of patches.

xen/stable is still a work in progress, but it should be suitable for 
general use.  It is based on xen/next (which is 2.6.32 based), but it 
also has the 2.6.32.x stable kernels merged into it.

At the moment it is missing a few features compared to xen/master; in 
particular it is missing PCI passthrough and ACPI power management.

This will become a long-term supported Xen kernel (as 2.6.32 is going to 
be a long-term supported Linux release).  There will also be a 
development tree which tracks ongoing Linux development.

I have try to change xen/master in xen/stable or xen/next but give error:
error: pathspec 'xen/stable' did not match any file(s) known to git.
error: pathspec 'xen/next' did not match any file(s) known to git.

[Fantu]

Now with config example in wiki page do very big modules and initrd, is
possible do same config without only not necessary for do more small?
