2008-10-15KVM: MMU: mode specific sync_pageMarcelo Tosatti
Examine guest pagetable and bring the shadow back in sync. Caller is responsible for local TLB flush before re-entering guest mode. Signed-off-by: Marcelo Tosatti <mtosatti@redhat.com> Signed-off-by: Avi Kivity <avi@redhat.com>
2008-10-15KVM: MMU: do not write-protect large mappingsMarcelo Tosatti
There is not much point in write protecting large mappings. This can only happen when a page is shadowed during the window between is_largepage_backed and mmu_lock acquision. Zap the entry instead, so the next pagefault will find a shadowed page via is_largepage_backed and fallback to 4k translations. Simplifies out of sync shadow.

2008-10-15KVM: MMU: move local TLB flush to mmu_set_spteMarcelo Tosatti

2008-10-15KVM: ia64: add support for Tukwila processorsXiantao Zhang
In Tukwila processor, VT-i has been enhanced in its implementation, it is often called VT-i2 techonology. With VTi-2 support, virtulization performance should be improved. In this patch, we added the related stuff to support kvm/ia64 for Tukwila processors. Signed-off-by: Xiantao Zhang <xiantao.zhang@intel.com> Signed-off-by: Avi Kivity <avi@redhat.com>
2008-10-15KVM: ia64: Implement a uniform vps interfaceXiantao Zhang

2008-10-15KVM: Don't destroy vcpu in case vcpu_setup failsGlauber Costa
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.

2008-10-15KVM: don't enter guest after SIPI was received by a CPUGleb Natapov
The vcpu should process pending SIPI message before entering guest mode again. kvm_arch_vcpu_runnable() returns true if the vcpu is in SIPI state, so we can't call it here. Signed-off-by: Gleb Natapov <gleb@qumranet.com> Signed-off-by: Avi Kivity <avi@redhat.com>

2008-10-15KVM: switch to get_user_pages_fastMarcelo Tosatti
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 <mtosatti@redhat.com> Signed-off-by: Avi Kivity <avi@redhat.com>
2008-10-15KVM: opencode gfn_to_page in kvm_vm_faultMarcelo Tosatti
kvm_vm_fault is invoked with mmap_sem held in read mode. Since gfn_to_page will be converted to get_user_pages_fast, which requires this lock NOT to be held, switch to opencoded get_user_pages. Signed-off-by: Marcelo Tosatti <mtosatti@redhat.com> Signed-off-by: Avi Kivity <avi@redhat.com>
2008-10-15KVM: Device Assignment: Free device structures if IRQ allocation failsAmit Shah
When an IRQ allocation fails, we free up the device structures and disable the device so that we can unregister the device in the userspace and not expose it to the guest at all. Signed-off-by: Amit Shah <amit.shah@redhat.com> Signed-off-by: Avi Kivity <avi@redhat.com>

2008-10-15[ARM] 5308/1: Fix Viper ISA IRQ handlingMarc Zyngier
The ISA IRQ renumbering broke the Viper ISA code in interesting ways. It originally assumed that ISA interrupt were numbered in the order that is defined by the CPLD registers. Unfortunately, this is no longer the case. Furthermore, the viper_irq_handler() function being a chained IRQ handler, it must ACK the interrupt by itself, or the handler will be immediately reentered, with the expected damages. This fix was made possible thanks to the help of David Raeman, who provided debug information and tested each version of this patch.

Add DstAcc operand type. That means that there are 4 bits now for DstMask. "In the good old days cpus would have only one register that was able to fully participate in arithmetic operations, typically called A for Accumulator. The x86 retains this tradition by having special, shorter encodings for the A register (like the cmp opcode), and even some instructions that only operate on A (like mul). SrcAcc and DstAcc would accommodate these instructions by decoding A into the corresponding 'struct operand'." -- Avi Kivity Signed-off-by: Guillaume Thouvenin <guillaume.thouvenin@ext.bull.net> Signed-off-by: Avi Kivity <avi@qumranet.com>
