* ia64 kvm fixes for O=... buildsAl Viro2008-04-28
| | | | | | | | | * EXTRA_CFLAGS do not apply for *.S * don't bother with symlinks to ../lib/mem*.S, just add ../lib/mem*.o to object list Signed-off-by: Al Viro <viro@zeniv.linux.org.uk> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
* KVM: add ioctls to save/store mpstateMarcelo Tosatti2008-04-27
| | | | | | | | | | | | | So userspace can save/restore the mpstate during migration. [avi: export the #define constants describing the value] [christian: add s390 stubs] [avi: ditto for ia64] Signed-off-by: Marcelo Tosatti <mtosatti@redhat.com> Signed-off-by: Christian Borntraeger <borntraeger@de.ibm.com> Signed-off-by: Carsten Otte <cotte@de.ibm.com> Signed-off-by: Avi Kivity <avi@qumranet.com>
* KVM: Rename VCPU_MP_STATE_* to KVM_MP_STATE_*Avi Kivity2008-04-27
| | | | | | We wish to export it to userspace, so move it into the kvm namespace. Signed-off-by: Avi Kivity <avi@qumranet.com>
* KVM: hlt emulation should take in-kernel APIC/PIT timers into accountMarcelo Tosatti2008-04-27
| | | | | | | | | | | | | | | | | | Timers that fire between guest hlt and vcpu_block's add_wait_queue() are ignored, possibly resulting in hangs. Also make sure that atomic_inc and waitqueue_active tests happen in the specified order, otherwise the following race is open: CPU0 CPU1 if (waitqueue_active(wq)) add_wait_queue() if (!atomic_read(pit_timer->pending)) schedule() atomic_inc(pit_timer->pending) Signed-off-by: Marcelo Tosatti <mtosatti@redhat.com> Signed-off-by: Avi Kivity <avi@qumranet.com>
