Add a smp_ops interface. This abstracts the API defined by <linux/smp.h> for use within arch/i386. The primary intent is that it be used by a paravirtualizing hypervisor to implement SMP, but it could also be used by non-APIC-using sub-architectures. This is related to CONFIG_PARAVIRT, but is implemented unconditionally since it is simpler that way and not a highly performance-sensitive

This adds an smp_ops for voyager, and hooks things up appropriately. This is the first baby-step to making subarch runtime switchable.

Hello list! https://www.redhat.com/archives/fedora-xen/2008-March/msg00013.html So it looks like dom0 pv_ops support is not yet ready to be included in Fedora 9 (to be released this spring) and in kernel.org upstream kernels. They're working hard on it, and it _should_ appear soon for testing.. The good news is that pv_ops domU for both 32bit and 64bit including paravirt framebuffer

Hi, i''ve new hardware for my XEN server. It boots pv_ops kernel now. But with my pv_ops kernel the server doesn''t power off. Even there isn''t this messages for it. When i boot a 2.6.24 from Ubuntu it power off. Regards, Stefan Kuhne _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com

Is pte_offset_map allowed to happen within lazy mmu? I presume not, because you definitely don't want the mapping pte update to be deferred. Or, more specifically, is kunmap_atomic ever allowed within lazy mmu? I'm looking at kpte_clear_flush; I've already got a patch which turns this into a pv_op, along with a Xen implementation. But I think its probably an excess pv_op for a

Hey! As I''ve already written about two days ago, I''m having major trouble getting blktap2 to work properly. After trying xen-sources-2.6.32-xen-r1 from Gentoo (where Andrew Lyon, the maintainer, has already confirmed that he''s hitting the same problem as me, i.e. the blktap2 driver is dysfunctional in the kernel), I decided to give a pv_ops-Kernel a try, and checked out

Hi all, I've been looking at the next steps to try to get Xen running fully on top of pv_ops. To that end, I've (just) started looking at one of the next major jobs --- i686 dom0 on pv_ops. There are still a number of things needing done to reach parity with xen-unstable: x86_64 xen on pv_ops Paravirt framebuffer/keyboard CPU hotplug Balloon kexec driver domains but it

I just noticed something interesting with the pv_ops dom0 kernel that I built from Jeremy''s git tree. When I run ''cat /proc/cpuinfo'' the output shows the processors have 0.000 MHz. Everything runs fine I just thought it was interesting. processor : 3 vendor_id : AuthenticAMD cpu family : 16 model : 4 model name : AMD Phenom(tm) II X4

Hi, I found this mail about network problems in the archive. I think I have the same network problems with a routing (with or without NAT) domU connected by two network bridges. The dom0 logs thousands of following messages: -- Attempting to checksum a non-TCP/UDP packet, dropping a protocol 1 packet -- and all outgoing TCP packets have wrong TCP checksums (traced on another machine on the
