Hi Everyone
Is there any progress with these patches?
Is there a chance they will be committed any time soon?
Thanks,

Now header files have gone into includes, so include file path
needs change also to avoid build break.

This patchset implements two msix masking optimizations.
It works fine for me but I did not have the time to do
performance testing yet so I do not know
whether it helps and which workloads.
Sending out now as I'll be on vacation for a week.
Please review and comment.
Thanks!

Support backend guest notifier masking in vhost-net:
create eventfd at device init, when masked,
make vhost use that as eventfd instead of
sending an interrupt.

some backends (notably vhost) can mask events
at their source in a way that is more efficient
than masking through kvm.
Specifically
- masking in kvm uses rcu write side so it has high latency
- in kvm on unmask we always send an interrupt
masking at source does not have these issues.

As vhost started is cleared last thing on stop,
set it first things on start. This makes it
possible to use vhost_started while start is in
progress which is used by follow-up patches.

Erik,
You can take a look at my recent post about usb tablet peforamnce over ehci, in
which I mentioned a libvirt config of how to let usb tablet connect to ehci.

I want to translate GFN(which is Guest physical address >> 12) to ram_addr.

Paolo,
As you wrote the fallback code which is used when sem_timedwait() is
missing could you please take a look at this when you have some time? I
can test any patches you might come up with.

Reading the spec, it is clear that most modes normally leave the IRQ
output line high, and only pulse it low to generate a leading edge.
Especially the most commonly used mode 2.
The KVM i8254 model does not try to emulate the duration of the pulse at
all, so just swap the high/low settings it to
Changes since version 1 (from Sep 9):
* Split off patch 1; this is the critical prerequisite to
make the i8254 work with the fixed i8259.
* Add patch 2, to make additional changes to the i8254
to make it consistent with the spec and with proposed changes
to qemu's i8254 model.
Intel's definition of "edge triggered" means: "asserted with a
low-to-high transition at the time an interrupt is registered
and then kept high until the interrupt is served via one of the
EOI mechanisms or goes away unhandled."
So the only difference between edge triggered and level triggered
is
Make git_get_out() consistent with spec. Currently pit_get_out()
doesn't affect IRQ0, but it can be read by the guest in other ways.
This makes it consistent with proposed changes in qemu's i8254 model
as well.
