KVM: Fix guest shared interrupt with in-kernel irqchip

2008-10-28T12:21:34+00:00

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

2008-10-15T12:25:35+00:00

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

2008-10-15T12:25:34+00:00

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

KVM: Move device assignment logic to common code

2008-10-15T12:25:33+00:00

To share with other archs, this patch moves device assignment logic to common parts. Signed-off-by: Xiantao Zhang Signed-off-by: Avi Kivity

KVM: MMU: out of sync shadow core

2008-10-15T12:25:25+00:00

Allow guest pagetables to go out of sync. Instead of emulating write accesses to guest pagetables, or unshadowing them, we un-write-protect the page table and allow the guest to modify it at will. We rely on invlpg executions to synchronize individual ptes, and will synchronize the entire pagetable on tlb flushes. Signed-off-by: Marcelo Tosatti Signed-off-by: Avi Kivity

KVM: Device Assignment with VT-d

2008-10-15T12:25:04+00:00

Based on a patch by: Kay, Allen M This patch enables PCI device assignment based on VT-d support. When a device is assigned to the guest, the guest memory is pinned and the mapping is updated in the VT-d IOMMU. [Amit: Expose KVM_CAP_IOMMU so we can check if an IOMMU is present and also control enable/disable from userspace] Signed-off-by: Kay, Allen M Signed-off-by: Weidong Han Signed-off-by: Ben-Ami Yassour Signed-off-by: Amit Shah Acked-by: Mark Gross Signed-off-by: Avi Kivity

KVM: x86: do not execute halted vcpus

2008-10-15T08:15:26+00:00

Offline or uninitialized vcpu's can be executed if requested to perform userspace work. Follow Avi's suggestion to handle halted vcpu's in the main loop, simplifying kvm_emulate_halt(). Introduce a new vcpu->requests bit to indicate events that promote state from halted to running. Also standardize vcpu wake sites.

KVM: Move KVM TRACE DEFINITIONS to common header

2008-10-15T08:15:12+00:00

Move KVM trace definitions from x86 specific kvm headers to common kvm headers to create a cross-architecture numbering scheme for trace events. This means the kvmtrace_format userspace tool won't need to know which architecture produced the log file being processed.

KVM: Synchronize guest physical memory map to host virtual memory map

2008-07-29T09:33:53+00:00

Synchronize changes to host virtual addresses which are part of a KVM memory slot to the KVM shadow mmu. This allows pte operations like swapping, page migration, and madvise() to transparently work with KVM. Signed-off-by: Andrea Arcangeli Signed-off-by: Avi Kivity

KVM: MMU: nuke shadowed pgtable pages and ptes on memslot destruction
