Previously we were using: 520 if ((HYPERVISOR_grant_table_op(GNTTABOP_setup_table, pset, 1) != 0) || 521 (pset->status != 0)) { even on HVM. Now, this isn''t actually necessary (stuff works fine with the call nop''d out, presumably due to the auto-sizing), but I wonder why the only grant op allowed is _query_size? IE what''s the statu...

I was following an email chain in the xen mailing list on HVM hypercalls on grant tables and the email chain link is below http://lists.xensource.com/archives/html/xen-devel/2007-03/msg00688.html This link says that we need not required hypercalls to share memory b/w HVM''s. But as far as my understanding of sharing memory is concerned, I think the memory is shared using grant table

Hi Jeremy. According to your suggestion, I recreated patches for Ingo's x86.git tree. And this patch series includes Eddie's modification. Please review and forward them. (or push back to respin.) Recently the xen-ia64 community started to make efforts to merge xen/ia64 Linux to upstream. The first step is to merge up domU portion. This patchset is preliminary for xen/ia64 domU linux

Hi. This patchset implements ia64/xen domU support based on ia64/pv_ops frame work which was sent as another patchest. Changes from take 5 are rebased to Linux 2.6.26-rc3, bug fix ivt.S paravirtualization and multi entry point support. I believe these patches can be applied to the linux ia64 repository. This patchset does the followings. - Some preparation work. Mainly importing header files to

Hi Andi, This series of patches implements the Xen paravirt-ops interface. It applies to 2.6.21-rc7 + your patches + the last batch of pv_ops patches I posted. This patch generally restricts itself to Xen-specific parts of the tree, though it does make a few small changes elsewhere. These patches include: - some helper routines for allocating address space and walking pagetables - Xen

It applies to 2.6.21-git13 + patches-2.6.21-git7-070507-1.tar.gz (I think "unwinder" is the only patch which doesn't apply to git13, and the sched-clock patches are the only ones which this series actually needs). Changes since the last posting: - More netfront review and cleanup - Added ability to

Hi, This is the Xen implementation for the paravirt_ops interface. The series is based on 2.6.22-rc1-mm1, and I think its ready to be cooked in -mm with a view to being merged in 2.6.23. The first part of the series is some small changes to the core kernel. Apart from the new code added in "Allocate and free vmalloc areas" (posted many times before), they are simply a few one-liners

Hi Andi, This series of patches implements the Xen paravirt-ops interface. It applies to 2.6.21-git3 + ff patches-2.6.21-git3-070501-1.tar.gz. Changes since the last posting: - reviews of xenbus (me), netfront (hch, rusty, herbert xu) and blockfront (hch), with most comments addressed. Netfront review revealed a couple of real bugs, and the code for all three is looking cleaner
