Yes. You would export the function in the USB core, and put a prototype
in a USB
on that but i 'm not sure that i understood.
Sure. I would actually suggest you first finish up the patch to issue a

remember what the status was.

% of the time the host controller is going to report
an OK status. And there's no guarantee that when the host does have an
error that it will set a bad status.
But without an analysis by perf, we won't really know where the
bottlenecks are.

Alan, does that seem correct?
The description of the behavior of ehci-hcd and uhci-hcd is correct.
ohci-hcd behaves the same way too. And they all agree with the

Alex was told to do when an isochronous TD had a completion code of

The KVM folks suggested that it would be good to get USB and
virtualization developers together to talk about how to virtualize the
xHCI host
. There
needs to be some way for the drivers to communicate their bandwidth
needs to the USB core. We've known about this issue for a while, and I
think it's time to get everyone in the same room and hash out an API.
(I will send out an API proposal later this month.)
Hope to see you there!

(), because of how the
xHCI hardware tracks endpoints. So even if we had the ideal interface,
the drivers would still need code like this to fall back to
less-bandwidth intensive alternate settings.
Is there a different way you think we should handle running out of
bandwidth?
