tools headers UAPI: Sync linux/kvm.h with the kernel sources

2021-03-10T12:18:30+00:00

To pick the changes in:

  30b5c851af7991ad ("KVM: x86/xen: Add support for vCPU runstate information")

That don't cause any change in tooling as it doesn't introduce any new
ioctl, just parameters to existing one.

This silences this perf build warning:

Merge tag 'kvmarm-5.12' of git://git.kernel.org/pub/scm/linux/kernel/git/kvmarm/kvmarm into HEAD

2021-02-12T16:23:44+00:00

KVM/arm64 updates for Linux 5.12

- Make the nVHE EL2 object relocatable, resulting in much more
  maintainable code
- Handle concurrent translation faults hitting the same page
  in a more elegant way
- Support for the standard TRNG hypervisor call
- A bunch of small PMU/Debug fixes
- Allow the disabling of symbol export from assembly code
- Simplification of the early init hypercall handling

KVM: PPC: Book3S HV: Introduce new capability for 2nd DAWR

2021-02-10T03:31:08+00:00

Introduce KVM_CAP_PPC_DAWR1 which can be used by QEMU to query whether
KVM supports 2nd DAWR or not. The capability is by default disabled
even when the underlying CPU supports 2nd DAWR. QEMU needs to check
and enable it manually to use the feature.

tools kvm headers: Update KVM headers from the kernel sources

2020-11-03T11:46:30+00:00

Some should cause changes in tooling, like the one adding LAST_EXCP, but
the way it is structured end up not making that happen.

The new SVM_EXIT_INVPCID should get used by arch/x86/util/kvm-stat.c,
in the svm_exit_reasons table.

The tools/perf/trace/beauty part has scripts to catch changes and
automagically create tables, like tools/perf/trace/beauty/kvm_ioctl.sh,
but changes are needed to make tools/perf/arch/x86/util/kvm-stat.c catch
those automatically.

These were handled by the existing scripts:
