Sched_op hypercall small questions
Greetings all.
Some small question regarding schedule poll operation hypercall.
1. struct sched_poll poll.timeout is measured in what unit of time?
Secs, ms? ns?
2. After issuing the hypercall_sched_op(SCHEDOP_poll, &poll); if no
timeout is used in poll struct how long will I yield the CPU?
3. If I issue the hypercall and the event never comes is it possible
to to yield the CPU for ever?
Thanks you very much for answering these questions.

hvm_init_ap_contexts
Why is there an argument returned in the function below (of hvm.h),
knowing that there is void?
static inline void
hvm_init_ap_context(struct vcpu_guest_context *ctxt,
int vcpuid, int trampoline_vector)
{
return hvm_funcs.init_ap_context(ctxt, vcpuid, trampoline_vector);
}

Xen PVM: Strange lockups when running PostgreSQL load
I am currently looking at a bug report[1] which is happening when
a Xen PVM guest with multiple VCPUs is running a high IO database
load (a test script is available in the bug report).
In experimenting it seems that this happens (or is getting more
likely) when the number of VCPUs is 8 or higher (though I have
not tried 6, only 2 and 4), having autogroup enabled seems to
make it more likely, too

[PATCH v2 0/6] Support calling functions on dedicated physical cpu
Some hardware (e.g. Dell Studio laptops) require special functions to
be called on physical cpu 0 in order to avoid occasional hangs. When
running as dom0 under Xen this could be achieved only via special boot
parameters (vcpu pinning) limiting the hypervisor in it's scheduling
decisions.
