[Qemu-devel] [PATCH 1/2] usb-hid: fixup changed tracking.

[Gerd Hoffmann]

Remove leftover calls to usb_hid_changed().

Take care to update the changed flag after delivering a event via
GET_REPORT like we do when sending events via interrupt endpoint.

[Qemu-devel] [PATCH 2/2] usb-uhci: fix irq handling on error.

[Gerd Hoffmann]

Spec on UHCI_STS_USBERR: "If the TD on which the error interrupt
occurred also had its IOC bit set, both this bit and Bit 0 are set."

Make UHCI emulation do that.

[Qemu-devel] [PULL] usb patch queue

[Gerd Hoffmann]

  Hi,

Next batch of usb updates.  This one brings packet queuing for uhci and
xhci, so we have per-endpoint queues at usb-bus level now.  Need to
bring those to the usb drivers as next step, so they (especially
usb-host) can pipeline requests.

Also a bunch of bugfixes in ehci, smartcard emulation and usb redirect.

cheers,
  Gerd

Pushed new branch usb.26.

Rebased to latest master, solved conflicts due to tracing merge, adapted 
to tracing changes ("disabled" not needed any more in trace-events). 
Squashed in a warning fix (init port variable) here:

>        usb-host: parse port in /proc/bus/usb/devices scan

Don't feel like spamming the list with these minor changes.  But can do 
a full repost if prefered.

please pull,
   Gerd

[Qemu-devel] [PULL] usb patch queue

[Gerd Hoffmann]

  Hi,

More usb and hid bits.  Fixes a usb tablet regression with windows xp.
milkymist goes use the new, splitted hid code directly instead of
(ab-)using the usb-kbd device, which in turn allows to kill the
usb_hid_datain_cb callback as no users are left.

please pull,
  Gerd

The following changes since commit b9c6cbff76061537b722d55f0e321dde2a612a23:

  Merge remote-tracking branch 'pm-arm/for-upstream' into pm (2011-08-09 19:16:43 +0200)

are available in the git repository at:

  git://git.kraxel.org/qemu usb.23

Gerd Hoffmann (2):
      usb/hid: add hid_pointer_activate, use it
      usb-hid: remove usb_hid_datain_cb

The same question as about spice queue: should
at least the regression fix go to stable?

Thanks,

Same answer ;)
The regression is present in master only, so no.

[Qemu-devel] [PULL] usb patch queue

[Gerd Hoffmann]

  Hi,

The USB patch queue is back!  I'm still busy catching up with the
backlog, I know I didn't pick up everything from the list yet.  If in
doubt it doesn't hurt to resend usb related patches, with me being
Cc'ed.

This pull brings old stuff, most of the patches are several months old
already.  Finally the usb-host fixes from Hans are queued up for merge.
Some async packet handling cleanups are in there to.  Oh, and one more
bugfix for the usb mass storage device.

please pull,
  Gerd

The following changes since commit d2d979c628e4b2c4a3cb71a31841875795c79043:

  NBD: Avoid leaking a couple of strings when the NBD device is closed (2011-05-03 11:29:21 +0200)

are available in the git repository at:
  git://git.kraxel.org/qemu usb.7.pull

Gerd Hoffmann (6):
      uhci: switch to QTAILQ
      uhci: keep uhci state pointer in async packet struct.
      ohci: get ohci state via container_of()
      musb: get musb state via container_of()
      usb: move complete callback to port ops
      usb: mass storage fix

Hans de Goede (8):
      usb-linux: introduce a usb_linux_alt_setting function
      usb-linux: Get the alt. setting from sysfs rather then asking the dev
      usb-linux: Add support for buffering iso usb packets
      usb-linux: Refuse packets for endpoints which are not in the usb descriptor
      usb-linux: Refuse iso packets when max packet size is 0 (alt setting 0)
      usb-linux: We only need to keep track of 15 endpoints
      usb-linux: Add support for buffering iso out usb packets
      usb: control buffer fixes
