We pass vcpu, vmx->fail, and vmx->launched to assembly code, but all three are fields within vmx. Consolidate by only passing in vmx and offsets for the rest. Signed-off-by: -

This changes kvm_write_guest_page/kvm_read_guest_page to use copy_to_user/read_from_user, as a result we get better speed and better dirty bit tracking. Signed-off-by:

If vmx fails to inject a real-mode interrupt while fetching the interrupt redirection table, it fails to record this in the vectoring information field. So we detect this condition and do it ourselves. Signed-off-by: -
Avi Kivity authored
We'll want to write to it in order to fix real-mode irq injection problems, but it is a read-only field. Storing it in a variable solves that issue. Signed-off-by: -
Avi Kivity authored
Instead of injecting real-mode interrupts by writing the interrupt frame into guest memory, abuse vmx by injecting a software interrupt. We need to pretend the software interrupt instruction had a length > 0, so we have to adjust rip backward. This lets us not to mess with writing guest memory, which is complex and also sleeps.

Now that rex_prefix is part of the decode cache, there is no need to pass it along. Signed-off-by: -

Instructions like 'inc reg' that have the register operand encoded in the opcode are currently specially decoded. Extend decode_register_operand() to handle that case, indicated by having DstReg or SrcReg without ModRM. Signed-off-by: -

This patch moves implementation of the following functions from kvm_main.c to x86.c: free_pio_guest_pages, vcpu_find_pio_dev, pio_copy_data, complete_pio, kernel_pio, pio_string_write, kvm_emulate_pio, kvm_emulate_pio_string The function inject_gp, which was duplicated by yesterday's patch series, is removed from kvm_main.c now because it is not needed anymore.

This patch moves the following functions to from kvm_main.c to x86.c: emulator_read/write_std, vcpu_find_pervcpu_dev, vcpu_find_mmio_dev, emulator_read/write_emulated, emulator_write_phys, emulator_write_emulated_onepage, emulator_cmpxchg_emulated, get_setment_base, emulate_invlpg, emulate_clts, emulator_get/set_dr, kvm_report_emulation_failure, emulate_instruction The following data type is moved to x86.c: struct x86_emulate_ops emulate_ops Signed-off-by:

This patch moves the implementation of the functions of kvm_get/set_msr, kvm_get/set_msr_common, and set_efer from kvm_main.c to x86.c. The definition of EFER_RESERVED_BITS is moved too. Signed-off-by:

KVM's nopage handler calls gfn_to_page() which acquires the mmap_sem when calling out to get_user_pages(). nopage handlers are already invoked with the mmap_sem held though. Introduce a __gfn_to_page() for use by the nopage handler which requires the lock to already be held. This was noticed by tglx. Signed-off-by:

This patch based on CR8/TPR patch, and enable the TPR shadow (FlexPriority) for 32bit Windows. Since TPR is accessed very frequently by 32bit Windows, especially SMP guest, with FlexPriority enabled, we saw significant performance gain. Signed-off-by:

This patch moves the definitions of CR0_RESERVED_BITS, CR4_RESERVED_BITS, and CR8_RESERVED_BITS along with the following functions from kvm_main.c to x86.c: set_cr0(), set_cr3(), set_cr4(), set_cr8(), get_cr8(), lmsw(), load_pdptrs() The static function wrapper inject_gp is duplicated in kvm_main.c and x86.c for now, the version in kvm_main.c should disappear once the last user of it is gone too. The function load_pdptrs is no longer static, and now defined in x86.h for the time being, until the last user of it is gone from kvm_main.c. Signed-off-by:

This patch moves the definition of segment_descriptor_64 for AMD64 and EM64T from kvm_main.c to segment_descriptor.h. It also adds a proper #ifndef...#define...#endif around that header file. The implementation of segment_base is moved from kvm_main.c to x86.c. Signed-off-by:

This patch splits kvm_vm_ioctl into archtecture independent parts, and x86 specific parts which go to kvm_arch_vcpu_ioctl in x86.c. The patch is unchanged since last submission. Common ioctls for all architectures are: KVM_CREATE_VCPU, KVM_GET_DIRTY_LOG, KVM_SET_USER_MEMORY_REGION x86 specific ioctls are: KVM_SET_MEMORY_REGION, KVM_GET/SET_NR_MMU_PAGES, KVM_SET_MEMORY_ALIAS, KVM_CREATE_IRQCHIP, KVM_CREATE_IRQ_LINE, KVM_GET/SET_IRQCHIP KVM_SET_TSS_ADDR Signed-off-by:
