SVM gets the DB and L bits for the cs by decoding the segment. This is in fact the completely generic code, so hoist it for kvm-lite to use. Signed-off-by: NRusty Russell <rusty@rustcorp.com.au> Signed-off-by: NAvi Kivity <avi@qumranet.com>

invlpg shouldn't fetch the "src" address, since it may not be valid, however SVM's "solution" which neuters emulation of all group 7 instruction is horrible and breaks kvm-lite. The simplest fix is to put a special check in for invlpg. Signed-off-by: NRusty Russell <rusty@rustcorp.com.au> Signed-off-by: NAvi Kivity <avi@qumranet.com>

APIC timer IRQ is set every time when a certain period expires at host time, but the guest may be descheduled at that time and thus the irq be overwritten by later fire. This patch keep track of firing irq numbers and decrease only when the IRQ is injected to guest or buffered in APIC.

Because lightweight exits (exits which don't involve userspace) are many times faster than heavyweight exits, it makes sense to emulate high usage devices in the kernel. The local APIC is one such device, especially for Windows and for SMP, so we add an APIC model to kvm. It also allows in-kernel host-side drivers to inject interrupts without going through userspace.

We need to check for signals inside the critical section, otherwise a signal can be sent which we will not notice. Also move the check before entry, so that if the signal happens before the first entry, we exit immediately instead of waiting for something to happen to the guest.

Both vmx and svm decode the I/O instructions, and both botch the job, requiring the instruction prefixes to be fetched in order to completely decode the instruction. So, if we see a string I/O instruction, use the x86 emulator to decode it, as it already has all the prefix decoding machinery. This patch defines ins/outs opcodes in x86_emulate.c and calls emulate_instruction() from io_interception() (svm.c) and from handle_io() (vmx.c). It removes all vmx/svm prefix instruction decoders (get_addr_size(), io_get_override(), io_address(), get_io_count()) Signed-off-by: NLaurent Vivier <Laurent.Vivier@bull.net> Signed-off-by: NAvi Kivity <avi@qumranet.com>

set_msr_interception() is used by svm to set up which MSRs should be intercepted. It can only fail if someone has changed the code to try to intercept an MSR without updating the array of ranges. The return value is ignored anyway: it should just BUG() if it doesn't work. (A build-time failure would be better, but that's tricky).

Changes some svm.c internal function names: 1) io_adress -> io_address (de-germanify the spelling) 2) kvm_reput_irq -> reput_irq (it's not a generic kvm function) 3) kvm_do_inject_irq -> (it's not a generic kvm function) Signed-off-by: NRusty Russell <rusty@rustcorp.com.au> Signed-off-by: NAvi Kivity <avi@qumranet.com>

Current kvm disables preemption while the new virtualization registers are in use. This of course is not very good for latency sensitive workloads (one use of virtualization is to offload user interface and other latency insensitive stuff to a container, so that it is easier to analyze the remaining workload). This patch re-enables preemption for kvm; preemption is now only disabled when switching the registers in and out, and during the switch to guest mode and back.

This patch converts the vcpus array in "struct kvm" to a pointer array, and changes the "vcpu_create" and "vcpu_setup" hooks into one "vcpu_create" call which does the allocation and initialization of the vcpu (calling back into the kvm_vcpu_init core helper).

When a vcpu causes a shadow tlb entry to have reduced permissions, it must also clear the tlb on remote vcpus. We do that by: - setting a bit on the vcpu that requests a tlb flush before the next entry - if the vcpu is currently executing, we send an ipi to make sure it exits before we continue Signed-off-by: NAvi Kivity <avi@qumranet.com>

Switch guest paging context may require us to allocate memory, which might fail. Instead of wiring up error paths everywhere, make context switching lazy and actually do the switch before the next guest entry, where we can return an error if allocation fails.
