[RFC PATCH v6 16/92] kvm: introspection: handle events and event replies
...ing. The same function
kvm_run_jobs_and_wait is an infinite loop before and gets a "break"
later. It is also not clear why kvmi_job_wait is called through a job.
Can you have instead just kvm_run_jobs in KVM_REQ_INTROSPECTION, and
something like this instead when sending an event:
int kvmi_wait_for_reply(struct kvm_vcpu *vcpu)
{
struct kvmi_vcpu *ivcpu = IVCPU(vcpu);
while (ivcpu->waiting_for_reply) {
kvmi_run_jobs(vcpu);
err = swait_event_killable(*wq,
!ivcpu->waiting_for_reply ||
!list_empty(&ivcpu->job_list));
if (err)
return -EINTR;
}
return 0;
}
?

[RFC PATCH v7 00/78] VM introspection
The KVM introspection subsystem provides a facility for applications
running on the host or in a separate VM, to control the execution of
other VMs (pause, resume, shutdown), query the state of the vCPUs (GPRs,
MSRs etc.), alter the page access bits in the shadow page tables (only
for the hardware backed ones, eg. Intel's EPT) and receive notifications
when events of interest have taken place
