* KVM: Portability: MMU initialization and teardown splitZhang Xiantao2008-01-30
| | | | | | | Move out kvm_mmu init and exit functionality from kvm_main.c Signed-off-by: Zhang Xiantao <xiantao.zhang@intel.com> Signed-off-by: Avi Kivity <avi@qumranet.com>
* KVM: Portability: Move kvm_vcpu_ioctl_get_dirty_log to arch-specific fileZhang Xiantao2008-01-30
| | | | | | | | Meanwhile keep the interface in common, and leave as more logic in common as possible. Signed-off-by: Zhang Xiantao <xiantao.zhang@intel.com> Signed-off-by: Avi Kivity <avi@qumranet.com>
* KVM: Make unloading of FPU state when putting vcpu arch-independentAmit Shah2008-01-30
| | | | | | | | | | | Instead of having each architecture do it individually, we do this in the arch-independent code (just x86 as of now). [avi: add svm to the mix, which was added to mainline during the 2.6.24-rc process] Signed-off-by: Amit Shah <amit.shah@qumranet.com> Signed-off-by: Avi Kivity <avi@qumranet.com>

* KVM: Add fpu_reload counterAvi Kivity2008-01-30
| | | | | | Measure the number of times we switch the fpu state. Signed-off-by: Avi Kivity <avi@qumranet.com>
* KVM: Replace 'light_exits' stat with 'host_state_reload'Avi Kivity2008-01-30
| | | | | | | | This is a little more accurate (since it counts actual reloads, not potential reloads), and reverses the sense of the statistic to measure a bad event like most of the other stats (e.g. we want to minimize all counters). Signed-off-by: Avi Kivity <avi@qumranet.com>
* KVM: Portability: Add two hooks to handle kvm_create and destroy vmZhang Xiantao2008-01-30
| | | | | | | | Add two arch hooks to handle kvm_create_vm and kvm destroy_vm. Now, just put io_bus init and destory in common. Signed-off-by: Zhang Xiantao <xiantao.zhang@intel.com> Signed-off-by: Avi Kivity <avi@qumranet.com>
* KVM: Remove __init attributes for kvm_init_debug and kvm_init_msr_listZhang Xiantao2008-01-30

| | | | | | | | | | | | | | | | | | 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.

* KVM: Portability: Split kvm_vm_ioctl v3Carsten Otte2008-01-30
| | | | | | | | | | | | | | | | | | | | 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: Carsten Otte <cotte@de.ibm.com> Reviewed-by: Christian Borntraeger <borntraeger@de.ibm.com> Acked-by: Hollis Blanchard <hollisb@us.ibm.com> Signed-off-by: Avi Kivity <avi@qumranet.com>
* KVM: Portability: split kvm_vcpu_ioctlCarsten Otte2008-01-30
| | | | | | | | | | | | | | | | | | | | | | | | This patch splits kvm_vcpu_ioctl into archtecture independent parts, and x86 specific parts which go to kvm_arch_vcpu_ioctl in x86.c. Common ioctls for all architectures are: KVM_RUN, KVM_GET/SET_(S-)REGS, KVM_TRANSLATE, KVM_INTERRUPT, KVM_DEBUG_GUEST, KVM_SET_SIGNAL_MASK, KVM_GET/SET_FPU Note that some PPC chips don't have an FPU, so we might need an #ifdef around KVM_GET/SET_FPU one day. x86 specific ioctls are: KVM_GET/SET_LAPIC, KVM_SET_CPUID, KVM_GET/SET_MSRS An interresting aspect is vcpu_load/vcpu_put. We now have a common vcpu_load/put which does the preemption stuff, and an architecture specific kvm_arch_vcpu_load/put. In the x86 case, this one calls the vmx/svm function defined in kvm_x86_ops.
