Hi,
Here is a update of the usb descriptor patches and a bunch of
improvements on top of that. This patch series features:
* Update USB section in MAINTAINERS
* A major overhaul for the usb descriptor handling for
emulated devices. This is in preparation for USB 2.0
support entering qemu which will need a bit more
sophisticated descriptor handling. This is also for
moving descriptor handling to common code instead of
having each driver duplicate it.
* Improved usb port management.
* Remote wakeup support, which allows guests to suspend
the usb bus when all devices are idle, so qemu will
not wakeup at usb frame rate (1000 Hz).
* A bunch of improvements and fixes for the usb-storage
emulation. It features full USB 2.0 support now, although
due to the lack of a EHCI controller the only thing you'll
notice is that the linux kernel logs a message which suggests
to connect the device to a high-speed port.
The patches are available in the git repository at:
git://anongit.freedesktop.org/spice/qemu usb.3
I think it would be very good to have in 0.14 (especially the remote
wakeup support and the storage fixes). Most patches have been on the
list already and are unmodified compared to the usb.2 branch posted a
week ago.
Note that I'll go disappear for x-mas and newyear holidays in a few
hours though, so I wouldn't be available to help fixing up any issues
which might pop up until january. Assuming we stick to the original
release schedule this isn't ideal of course. Given that the master
branch hasn't seen any commits this week I have my doubts that we see
rc0 today though.
FYI: I have some more experimental stuff which isn't ready for merge
yet in the queue:
* EHCI controller.
* Initial migration support for usb (not complete yet, not all devices
are covered, doesn't handle usb transactions which are in flight at
migration time, should already work fine for idle usb devices though).
* First bits of packet workflow cleanups.
If you wanna play with this: the git tree with these experimental and
in-progress bits is here:
git://anongit.freedesktop.org/spice/qemu usb.3.wip
enjoy & happy x-mas,
Gerd
