The purpose of the KVM_SET_SIGNAL_MASK API is to let userspace "kick"
a VCPU out of KVM_RUN through a POSIX signal.  A signal is attached
to a dummy signal handler; by blocking the signal outside KVM_RUN and
unblocking it inside, this possible race is closed:

          VCPU thread                     service thread
   --------------------------------------------------------------
        check flag
                                          set flag
                                          raise signal
        (signal handler does nothing)
        KVM_RUN

However, one issue with KVM_SET_SIGNAL_MASK is that it has to take
tsk->sighand->siglock on every KVM_RUN.  This lock is often on a
remote NUMA node, because it is on the node of a thread's creator.
Taking this lock can be very expensive if there are many userspace
exits (as is the case for SMP Windows VMs without Hyper-V reference
time counter).

As an alternative, we can put the flag directly in kvm_run so that
KVM can see it:

          VCPU thread                     service thread
   --------------------------------------------------------------
                                          raise signal
        signal handler
          set run->immediate_exit
        KVM_RUN
          check run->immediate_exit

This is what the last patch in this series does, together with
the corresponding kernel API.  The first six patches are a long
detour in the signal handling code, moving KVM-specific stuff
from cpus.c to kvm-all.c so that we have a better hook point for
KVM_CAP_IMMEDIATE_EXIT (patches 1-3, 6).

Because KVM_SET_SIGNAL_MASK is also unblocking SIGBUS so that
BUS_MCEERR_AR actions can be delivered via sigwait, we also have
to rewrite it (patch 4-5) to avoid sigwait, stowing the machine check
exception as soon as KVM_RUN exits and process it outside the signal
handler.

The seventh patch would of course be split between a linux-headers
update and the rest.

Paolo

ps: As an aside, I finally figured out how to test machine check
forwarding and I hope to write something about it.

The cast is there because sigbus_handler is invoked via sigfd_handler.
But it feels just wrong to use struct qemu_signalfd_siginfo in the
prototype of a function that is passed to sigaction.

Instead, do a simple-minded conversion of qemu_signalfd_siginfo to
siginfo_t.

* [PATCH 3/7] cpus: reorganize signal handling code
  2017-02-10  9:50 ` [Qemu-devel] " Paolo Bonzini
@ 2017-02-10  9:50   ` Paolo Bonzini

From: Paolo Bonzini @ 2017-02-10  9:50 UTC (permalink / raw)
  To: qemu-devel; +Cc: kvm

Move the KVM "eat signals" code under CONFIG_LINUX, in preparation
for moving it to kvm-all.c; reraise non-MCE SIGBUS immediately,
without passing it to KVM.

* [Qemu-devel] [PATCH 3/7] cpus: reorganize signal handling code
@ 2017-02-10  9:50   ` Paolo Bonzini

From: Paolo Bonzini @ 2017-02-10  9:50 UTC (permalink / raw)
  To: qemu-devel; +Cc: kvm

Move the KVM "eat signals" code under CONFIG_LINUX, in preparation
for moving it to kvm-all.c; reraise non-MCE SIGBUS immediately,
without passing it to KVM.

Build it on kvm_arch_on_sigbus_vcpu instead.  They do the same
for "action optional" SIGBUSes, and the main thread should never get
"action required" SIGBUSes because it blocks the signal.

* [PATCH 7/7] KVM: use KVM_CAP_IMMEDIATE_EXIT
  2017-02-10  9:50 ` [Qemu-devel] " Paolo Bonzini
@ 2017-02-10  9:50   ` Paolo Bonzini

  To: qemu-devel; +Cc: kvm

The purpose of the KVM_SET_SIGNAL_MASK API is to let userspace "kick"
a VCPU out of KVM_RUN through a POSIX signal.  A signal is attached
to a dummy signal handler; by blocking the signal outside KVM_RUN and
unblocking it inside, this possible race is closed:

          VCPU thread                     service thread
   --------------------------------------------------------------
        check flag
                                          set flag
                                          raise signal
        (signal handler does nothing)
        KVM_RUN

However, one issue with KVM_SET_SIGNAL_MASK is that it has to take
tsk->sighand->siglock on every KVM_RUN.  This lock is often on a
remote NUMA node, because it is on the node of a thread's creator.
Taking this lock can be very expensive if there are many userspace
exits (as is the case for SMP Windows VMs without Hyper-V reference
time counter).

KVM_CAP_IMMEDIATE_EXIT provides an alternative, where the flag is
placed directly in kvm_run so that KVM can see it:

          VCPU thread                     service thread
   --------------------------------------------------------------
                                          raise signal
        signal handler
          set run->immediate_exit
        KVM_RUN
          check run->immediate_exit

The previous patches changed QEMU so that the only blocked signal is
SIG_IPI, so we can now stop using KVM_SET_SIGNAL_MASK and sigtimedwait
if KVM_CAP_IMMEDIATE_EXIT is available.

On a 14-VCPU guest, an "inl" operation goes down from 30k to 6k on
an unlocked (no BQL) MemoryRegion, or from 30k to 15k if the BQL
is involved.

This is needed to test these patches with the final version of the KVM part:
