KVM: Fix guest shared interrupt with in-kernel irqchip

2008-10-28T12:21:34Z

Every call of kvm_set_irq() should offer an irq_source_id, which is allocated by kvm_request_irq_source_id(). Based on irq_source_id, we identify the irq source and implement logical OR for shared level interrupts. The allocated irq_source_id can be freed by kvm_free_irq_source_id(). Currently, we support at most sizeof(unsigned long) different irq sources. [Amit: - rebase to kvm.git HEAD - move definition of KVM_USERSPACE_IRQ_SOURCE_ID to common file - move kvm_request_irq_source_id to the update_irq ioctl] [Xiantao: - Add kvm/ia64 stuff and make it work for kvm/ia64 guests] Signed-off-by: Sheng Yang Signed-off-by: Amit Shah Signed-off-by: Xiantao Zhang Signed-off-by: Avi Kivity

KVM: Separate irq ack notification out of arch/x86/kvm/irq.c

2008-10-15T12:25:35Z

Moving irq ack notification logic as common, and make it shared with ia64 side. Signed-off-by: Xiantao Zhang Signed-off-by: Avi Kivity

KVM: Change is_mmio_pfn to kvm_is_mmio_pfn, and make it common for all archs

2008-10-15T12:25:34Z

Add a kvm_ prefix to avoid polluting kernel's name space. Signed-off-by: Xiantao Zhang Signed-off-by: Avi Kivity

KVM: Device Assignment: Map mmio pages into VT-d page table

2008-10-15T12:25:29Z

Assigned device could DMA to mmio pages, so also need to map mmio pages into VT-d page table. Signed-off-by: Weidong Han Signed-off-by: Avi Kivity

KVM: Remove useless intel-iommu.h header inclusion

2008-10-15T12:25:11Z

Currently "#include " is not needed in virt/kvm/kvm_main.c. Signed-off-by: Weidong Han Signed-off-by: Avi Kivity

KVM: Don't destroy vcpu in case vcpu_setup fails

2008-10-15T12:25:10Z

One of vcpu_setup responsibilities is to do mmu initialization. However, in case we fail in kvm_arch_vcpu_reset, before we get the chance to init mmu. OTOH, vcpu_destroy will attempt to destroy mmu, triggering a bug. Keeping track of whether or not mmu is initialized would unnecessarily complicate things. Rather, we just make return, making sure any needed uninitialization is done before we return, in case we fail. Signed-off-by: Glauber Costa Signed-off-by: Avi Kivity

KVM: switch to get_user_pages_fast

2008-10-15T12:25:06Z

Convert gfn_to_pfn to use get_user_pages_fast, which can do lockless pagetable lookups on x86. Kernel compilation on 4-way guest is 3.7% faster on VMX. Signed-off-by: Marcelo Tosatti Signed-off-by: Avi Kivity
