Hi Greg,
Here are some xHCI patches that I hope can be included in 2.6.39. They
include some cleanups in the xHCI driver and USB core, the isochronous
bug fixes you said were too late to make it into 2.6.38, and (finally!)
USB 3.0 hub support.
The hub support patches rework the xHCI driver to register two roothubs:
a USB 2.0 roothub and a USB 3.0 roothub. This reflects the behavior of
external USB 3.0 hubs, because they actually show up as two USB devices.
There was a fair bit of USB core work that needed to go in to support
registering two roothubs for one PCI device. Fortunately, those patches
have gone through four different revisions, and I've addressed the last
of Alan Stern's comments (including the issue with an extern inline
function).
The patches have passed my stress tests, and have passed Paul
Zimmerman's testing with Synopsis USB devices. The full patches will be
sent to the linux-usb mailing list.
