KVM: PPC: BookE: Load the lower half of MSR

2010-11-05T16:42:29Z

This was preventing the guest from setting any bits in the hardware MSR which aren't forced on, such as MSR[SPE]. Signed-off-by: Scott Wood Signed-off-by: Alexander Graf

KVM: PPC: BookE: fix sleep with interrupts disabled

2010-11-05T16:42:28Z

It is not legal to call mutex_lock() with interrupts disabled. This will assert with debug checks enabled. If there's a real need to disable interrupts here, it could be done after the mutex is acquired -- but I don't see why it's needed at all.

KVM: PPC: e500: Call kvm_vcpu_uninit() before kvmppc_e500_tlb_uninit().

2010-11-05T16:42:28Z

The VCPU uninit calls some TLB functions, and the TLB uninit function frees the memory used by them. Signed-off-by: Scott Wood Acked-by: Liu Yu Signed-off-by: Alexander Graf

KVM: PPC: fix information leak to userland

2010-11-05T16:42:26Z

Structure kvm_ppc_pvinfo is copied to userland with flags and pad fields unitialized. It leads to leaking of contents of kernel stack memory. Signed-off-by: Vasiliy Kulikov Signed-off-by: Marcelo Tosatti

KVM: PPC: Fix compile error in e500_tlb.c

2010-10-24T08:52:22Z

The e500_tlb.c file didn't compile for me due to the following error: arch/powerpc/kvm/e500_tlb.c: In function ‘kvmppc_e500_shadow_map’: arch/powerpc/kvm/e500_tlb.c:300: error: format ‘%lx’ expects type ‘long unsigned int’, but argument 2 has type ‘gfn_t’ So let's explicitly cast the argument to make printk happy.

KVM: PPC: e500_tlb: Fix a minor copy-paste tracing bug

2010-10-24T08:52:21Z

The kvmppc_e500_stlbe_invalidate() function was trying to pass too many parameters to trace_kvm_stlb_inval(). This appears to be a bad copy-paste from a call to trace_kvm_stlb_write(). Signed-off-by: Kyle Moffett Signed-off-by: Alexander Graf

KVM: PPC: Implement level interrupts for BookE

2010-10-24T08:52:20Z

BookE also wants to support level based interrupts, so let's implement all the necessary logic there. We need to trick a bit here because the irqprios are 1:1 assigned to architecture defined values. But since there is some space left there, we can just pick a random one and move it later on - it's internal anyways. Signed-off-by: Alexander Graf

KVM: PPC: Expose level based interrupt cap

2010-10-24T08:52:19Z

Now that we have all the level interrupt magic in place, let's expose the capability to user space, so it can make use of it! Signed-off-by: Alexander Graf

KVM: PPC: Implement Level interrupts on Book3S

2010-10-24T08:52:19Z

The current interrupt logic is just completely broken. We get a notification from user space, telling us that an interrupt is there. But then user space expects us that we just acknowledge an interrupt once we deliver it to the guest. This is not how real hardware works though. On real hardware, the interrupt controller pulls the external interrupt line until it gets notified that the interrupt was received. So in reality we have two events: pulling and letting go of the interrupt line. To maintain backwards compatibility, I added a new request for the pulling part. The letting go part was implemented earlier already. With this in place, we can now finally start guests that do not randomly stall and stop to work at random times. This patch implements above logic for Book3S. Signed-off-by: Alexander Graf
