KVM: x86: Add code to track call origin for msr assignment

2012-11-30T20:26:12+00:00

In order to track who initiated the call (host or guest) to modify an msr value I have changed function call parameters along the call path. The specific change is to add a struct pointer parameter that points to (index, data, caller) information rather than having this information passed as individual parameters. The initial use for this capability is for updating the IA32_TSC_ADJUST msr while setting the tsc value. It is anticipated that this capability is useful for other tasks.

KVM: use jump label to optimize checking for in kernel local apic presence

2012-08-06T16:00:44+00:00

Usually all vcpus have local apic pointer initialized, so the check may be completely skipped. Signed-off-by: Gleb Natapov Signed-off-by: Avi Kivity

KVM: x86: add paging gcc optimization

2012-04-08T11:03:13+00:00

Since most guests will have paging enabled for memory management, add likely() optimization around CR0.PG checks. Signed-off-by: Davidlohr Bueso Signed-off-by: Avi Kivity

KVM: Move cpuid code to new file

2011-12-27T09:21:49+00:00

The cpuid code has grown; put it into a separate file. Signed-off-by: Avi Kivity

KVM: MMU: cache mmio info on page fault path

2011-07-24T08:50:26+00:00

If the page fault is caused by mmio, we can cache the mmio info, later, we do not need to walk guest page table and quickly know it is a mmio fault while we emulate the mmio instruction Signed-off-by: Xiao Guangrong Signed-off-by: Avi Kivity

KVM: nVMX: Implement VMPTRST

KVM: nVMX: Decoding memory operands of VMX instructions

2011-07-12T08:45:11+00:00

This patch includes a utility function for decoding pointer operands of VMX instructions issued by L1 (a guest hypervisor) Signed-off-by: Nadav Har'El Signed-off-by: Marcelo Tosatti

KVM: fix push of wrong eip when doing softint

2011-05-11T11:57:09+00:00

When doing a soft int, we need to bump eip before pushing it to the stack. Otherwise we'll do the int a second time. [apw@canonical.com: merged eip update as per Jan's recommendation.] Signed-off-by: Serge E. Hallyn Signed-off-by: Andy Whitcroft Signed-off-by: Avi Kivity

KVM: SVM: Do not report xsave in supported cpuid

2010-12-08T15:28:37+00:00

To support xsave properly for the guest the SVM module need software support for it. As long as this is not present do not report the xsave as supported feature in cpuid. As a side-effect this patch moves the bit() helper function into the x86.h file so that it can be used in svm.c too. KVM-Stable-Tag. Signed-off-by: Joerg Roedel Signed-off-by: Avi Kivity

KVM: Add kvm_inject_realmode_interrupt() wrapper

2010-10-24T08:53:01+00:00

This adds a wrapper function kvm_inject_realmode_interrupt() around the emulator function emulate_int_real() to allow real mode interrupt injection.
