[PATCH] KVM: PPC: Make BAT only guest segments work

When a guest sets its SR entry to invalid, we may still find a corresponding entry in a BAT. So we need to make sure we're not faulting on invalid SR entries, but instead just claim them to be BAT resolved. This resolves breakage experienced when using libogc based guests. Signed-off-by:

[PATCH] KVM: PPC: Use kernel hash function

The linux kernel already provides a hash function. Let's reuse that instead of reinventing the wheel! Signed-off-by: Alexander Graf ag...@suse.de --- arch/powerpc/kvm/book3s_32_mmu_host.c | 10 ++ arch/powerpc/kvm/book3s_64_mmu_host.c | 11 ++- 2 files changed, 4

[PATCH] KVM: PPC: Remove obsolete kvmppc_mmu_find_pte

Initially we had to search for pte entries to invalidate them. Since the logic has improved since then, we can just get rid of the search function. Signed-off-by: Alexander Graf ag...@suse.de --- arch/powerpc/include/asm/kvm_book3s.h |1 - arch/powerpc/kvm/book3s_32_mmu_host.c | 20

[PATCH 2/2] KVM: PPC: Make use of hash based Shadow MMU

We just introduced generic functions to handle shadow pages on PPC. This patch makes the respective backends make use of them, getting rid of a lot of duplicate code along the way. Signed-off-by: Alexander Graf ag...@suse.de --- arch/powerpc/include/asm/kvm_book3s.h |7 ++

PVnize instructions

I figured I go and try to find out what the emulation distribution is in random use cases. The one I measured here was a: $ for i in `seq 1000`; do ls -la /dev/null; done inside the guest. This should give pretty good hints on process spawning overhead. Below are the results on what is issued
