That doesn't make sense: why would you do an expensive TCG translation
every time you hit the same code? After the first encounter, if the
code page hasn't been modified, it should be a TB cache lookup to
already translated code.

See if boosting the priority of the VM (see man chrt), and locking it to
a core (see man taskset) helps. You'll want to do that for the vcpu
thread(s) (in the qmeu monitor, run 'info cpus' command).

This driver must work for all kernels, whether they have SRIOV support or not.
Presumably the #ifdef CONFIG_PCI_IOV would be stripped for a kernel driver
where the kernel configures SR-IOV support.
I'll let John Ronciak respond on the issue of upstream review.

We have been waiting for the kernel IOV work to be in place upstream completely
before we submitted the drivers. Jeff Garzik won't take driver changes that
have no user. So as the kernel work completes, we'll submit the driver(s).
We have been talking about putting out the changes as RFC. If

Wouldn't it make more sense for the IOV code to be reworked to not
require #ifdefs in a driver? There se

Is this driver already upstream? If so, can you just send the di
Hi,
Here's the 6th version of this patch. I've split out the part with the
opaque env pointer through libkvm and the tiny patch for the bool.
Hence, this patch obviously require my two previous patches.
Let me know if there's further objections.
Thanks,
Jes

Hi,
In support of Avi's preference for half line patches, I split out the
bool eliminating bits too.

Replace unnecessary use of _Bool type with int.

I've have setup a couple virtual machines and they work great... for anywhere
between 2-24 hours. But then, for no reason I can determine, they just go 100%
