Instead of each subarch doing its own thing, add an API for queuing an injection, and manage failed exception injection centerally (i.e., if an inject failed due to a shadow page fault, we need to requeue it). Signed-off-by: NAvi Kivity <avi@qumranet.com>

Change dest_Loest_Prio -> IOAPIC_LOWEST_PRIORITY dest_Fixed -> IOAPIC_FIXED the original names are x86 specific, while the ioapic code will be reused for ia64. Signed-off-by: NZhang Xiantao <xiantao.zhang@intel.com> Signed-off-by: NAvi Kivity <avi@qumranet.com>

This patch replaces lapic structure with kvm_vcpu in ioapic.c, making ioapic independent of the local apic, as required by ia64. Signed-off-by: NZhang Xiantao <xiantao.zhang@intel.com> Signed-off-by: NAvi Kivity <avi@qumranet.com>

This patch removes the KVM specific defines for MSR_EFER that were being used in the svm support file and migrates all references to use instead the ones from the kernel headers that are used everywhere else and that have the same values.

Currently, make headers_check barfs due to <asm/kvm.h>, which <linux/kvm.h> includes, not existing. Rather than add a zillion <asm/kvm.h>s, export kvm.h only if the arch actually supports it. Signed-off-by: NAvi Kivity <avi@qumranet.com>

Unify the special instruction switch with the regular instruction switch, and the two byte special instruction switch with the regular two byte instruction switch. That makes it much easier to find an instruction or the place an instruction needs to be added in. Signed-off-by: NAvi Kivity <avi@qumranet.com>

This patch fixes a small issue where sturctures: kvm_pic_state kvm_ioapic_state are defined inside x86 specific code and may or may not be defined in anyway for other architectures. The problem caused is one cannot compile userspace apps (ex. libkvm) for other archs since a size cannot be determined for these structures.

cmps and scas instructions accept repeat prefixes F3 and F2. So in order to emulate those prefixed instructions we need to be able to know if prefixes are REP/REPE/REPZ or REPNE/REPNZ. Currently kvm doesn't make this distinction. This patch introduces this distinction.

The current cpuid management suffers from several problems, which inhibit passing through the host feature set to the guest: - No way to tell which features the host supports While some features can be supported with no changes to kvm, others need explicit support. That means kvm needs to vet the feature set before it is passed to the guest. - No support for indexed or stateful cpuid entries Some cpuid entries depend on ecx as well as on eax, or on internal state in the processor (running cpuid multiple times with the same input returns different output). The current cpuid machinery only supports keying on eax. - No support for save/restore/migrate The internal state above needs to be exposed to userspace so it can be saved or migrated. This patch adds extended cpuid support by means of three new ioctls: - KVM_GET_SUPPORTED_CPUID: get all cpuid entries the host (and kvm) supports - KVM_SET_CPUID2: sets the vcpu's cpuid table - KVM_GET_CPUID2: gets the vcpu's cpuid table, including hidden state [avi: fix original KVM_SET_CPUID not removing nx on non-nx hosts as it did before] Signed-off-by: NDan Kenigsberg <danken@qumranet.com> Signed-off-by: NAvi Kivity <avi@qumranet.com>
