Marcelo Tosatti	7ec5458821	KVM: Add kvm_read_guest_atomic() ... In preparation for a mmu spinlock, add kvm_read_guest_atomic() and use it in fetch() and prefetch_page(). Signed-off-by: Marcelo Tosatti <mtosatti@redhat.com> Signed-off-by: Avi Kivity <avi@qumranet.com>	2008-01-30 18:01:20 +02:00
Marcelo Tosatti	10589a4699	KVM: MMU: Concurrent guest walkers ... Do not hold kvm->lock mutex across the entire pagefault code, only acquire it in places where it is necessary, such as mmu hash list, active list, rmap and parent pte handling. Allow concurrent guest walkers by switching walk_addr() to use mmap_sem in read-mode. And get rid of the lockless __gfn_to_page. [avi: move kvm_mmu_pte_write() locking inside the function] [avi: add locking for real mode] [avi: fix cmpxchg locking] Signed-off-by: Marcelo Tosatti <mtosatti@redhat.com> Signed-off-by: Avi Kivity <avi@qumranet.com>	2008-01-30 18:01:20 +02:00
Avi Kivity	edf884172e	KVM: Move arch dependent files to new directory arch/x86/kvm/ ... This paves the way for multiple architecture support. Note that while ioapic.c could potentially be shared with ia64, it is also moved. Signed-off-by: Avi Kivity <avi@qumranet.com>	2008-01-30 18:01:18 +02:00
