Hey, Mukesh had posted them quite a while ago - they got reviewed, acked, etc, put in #linux-next, got patches to fix some things from folks. Then everybody focused on the Xen patches .. and now that is mostly baked this is what is needed on the Linux side to make it work with PVH. I had them based on v3.6, then merged on v3.11, then.. Decided to rebase all of them on v3.13-rc3 to make it easier. Couple of things: a) the patch: [PATCH V10 14/14] xen/pvh: vcpu info placement, load CS selector, could be split in three - and I think Mukesh did have a version like that. I can do it myself and will - it should be obvious of how it will be done. b). Regression testing - I ran this with a Linux kernel dom0 (32 and 64) on the latest Xen hypervisor without PVH enabled. It booted all the guests I had: RHEL5, SLES11, SLES12, F15, F16, F17, F18, F19, OEL5, OEL6, NetBSD PV, FreeBSD HVM; and also 32 and 64 PV and PVHVM combination of the same kernel (and save/restore on those). Nothing broke. c). I hadn''t tested it all with PVH enabled. Mukesh I believe has one or two patches that need to be put on top of this to make it work with the hypervisor changes. These patches are also available on: git://git.kernel.org/pub/scm/linux/kernel/git/konrad/xen.git devel/pvh.v10 [but they are out-dated a bit - I messed up on that branch and some of the authorships are assigned to me instead of Mukesh.

I think this should be sorted out as it makes it too difficult to review carefully (I''ve only given the series a quick, initial review).> Couple of things: > > a) the patch: > [PATCH V10 14/14] xen/pvh: vcpu info placement, load CS selector, > > could be split in three - and I think Mukesh did have a version like that. > I can do it myself and will - it should be obvious of how it will be done. > > b).

Nothing broke.That''s good to know. David
