tools: kvm_stat: Add comments (2016-05-25 16:12:06 +0200)
----------------------------------------------------------------
- move kvm_stat tool from QEMU repo into tools/kvm/kvm_stat
(kvm_stat had nothing to do with QEMU in the first place -- the tool
only interprets debugfs)
- expose per-vm statistics in debugfs and support them in kvm_stat
(KVM always collected per-vm statistics, but they were summarised into
global statistics)
x86:
- fix dynamic APICv (VMX was improperly configured and a guest could
access host's APIC MSRs, CVE-2016-4440)
- minor fixes
ARM changes from Christoffer Dall:
"This set of changes include the new vgic, which is a reimplementation
of our horribly broken legacy vgic implementation. The two
implementations will live side-by-side (with the new being the
configured default) for one kernel release and then we'll remove the
legacy one.
Also fixes a non-critical issue with virtual abort injection to
guests."
