Hi,
This patch set enables guest SMP when using in-kernel APIC. It is
independent from the partial kernel apic SMP patch from Avi. We are
posting it here for comments and possible merging with that patch. The
patch set is based on:
KVM: lapic5 branch: e9ddfaf472 (Remove dead code) with a patch
that undoes 34735648ce (apic: implement init/sipi, work in progress),
see the attachment in [PATCH 0/7].
kvm-userspace: lapic5 branch: 206d1aa22f (qemu: prevent set
wrong cr8 when using irqchip).
btw, I can't find the cr8 patch in kvm-userspace from kvm-userspace.git,
but it is in kvm-commits mailing list. Is there anything happened when
kvm-userspace relocates on kernel.org or am I missing anything?
The patch set is:
[PATCH 0/7] :this post, and a temporary sipi/init undo patch
[PATCH 1/7] is a preparation patch for userspace
[PATCH 2/7] and [PATCH 3/7] are bug fixes for kernel
[PATCH 4/7] modifies the PIC interrupt routing for SMP
[PATCH 5/7] enables round robin for the apic lowest priority
delivery
[PATCH 6/7] is the main patch for SMP support. It handles
SIPI/INIT in the kernel
[PATCH 7/7] is the usermode part for SMP support, which disables
userleve SIPI/INIT handling
I have tested some situation, 32bit SMP Windows xp/srv2k3 and Linux
2.6.9/2.6.18 all works fine using in-kernel apics. User mode APICs also
works fine. Test for other environments is ongoing.
[PATCH 6/7] and [PATCH 7/7] have additional comments, please see the
corresponding post.
Any comments are welcomed.
Thanks,
Qing
