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.

cpus: remove ugly cast on sigbus_handler

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 4/7] KVM: remove kvm_arch_on_sigbus

To: qemu-devel; +Cc: 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 5/7] KVM: do not use sigtimedwait to catch SIGBUS

Call kvm_on_sigbus_vcpu asynchronously from the VCPU thread.
Information for the SIGBUS can be stored in thread-local variables
and processed later in kvm_cpu_exec.

* [Qemu-devel] [PATCH 5/7] KVM: do not use sigtimedwait to catch SIGBUS
@ 2017-02-10 9:50 ` Paolo Bonzini
0 siblings, 0 replies; 20+ messages in thread
From: Paolo Bonzini @ 2017-02-10 9:50 UTC (permalink / raw)
To: qemu-devel; +Cc: kvm
Call kvm_on_sigbus_vcpu asynchronously from the VCPU thread.
Information for the SIGBUS can be stored in thread-local variables
and processed later in kvm_cpu_exec.

* [PATCH 7/7] KVM: use KVM_CAP_IMMEDIATE_EXIT

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.
