Hi Greg,
Here's 76 patches to queue to usb-next for 3.15.
The bulk of this rather large pull request is the UAS driver cleanup, the
xHCI streams fixes, and the new userspace API for usbfs to be able to use
and alloc/free bulk streams. I've hammered on these changes, and the UAS
driver seems solid. The performance numbers are pretty spiffy too:
root@xanatos:~# echo 3 > /proc/sys/vm/drop_caches; dd if=/dev/sdb of=/dev/null bs=4k count=1000M iflag=count_bytes
256000+0 records in
256000+0 records out
1048576000 bytes (1.0 GB) copied, 3.28557 s, 319 MB/s
That's about 100 MB/s faster than my fastest Bulk-only-Transport mass
storage drive.
There's a couple of miscellaneous cleanup patches and non-urgent bug fixes
in here as well:
7969943789 xhci: add the meaningful IRQ description if it is empty
bcffae7708 xhci: Prevent runtime pm from autosuspending during initialization
e587b8b270 xhci: make warnings greppable
25cd2882e2 usb/xhci: Change how we indicate a host supports Link PM.
