2011-08-04usb: use iovecs in USBPacketGerd Hoffmann1-21/+25
Zap data pointer from USBPacket, add a QEMUIOVector instead. Add a bunch of helper functions to manage USBPacket data. Switch over users to the new interface. Note that USBPacket->len was used for two purposes: First to pass in the buffer size and second to return the number of transfered bytes or the status code on async transfers. There is a new result variable for the latter. A new status code was added to catch uninitialized result. Nobody creates iovecs with more than one element (yet). Some users are (temporarely) limited to iovecs with a single element to keep the patch size as small as possible. Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>

2011-06-24Strip trailing '\n' from error_report()'s first argumentMarkus Armbruster1-1/+1
error_report() prepends location, and appends a newline. The message constructed from the arguments should not contain a newline. Fix the obvious offenders. Signed-off-by: Markus Armbruster <armbru@redhat.com> Signed-off-by: Stefan Hajnoczi <stefanha@linux.vnet.ibm.com>
2011-06-23usb: Add a speedmask to devicesHans de Goede1-0/+1
This is used to indicate at which speed[s] the device can operate, so that this can be checked to match the ports capabilities when it gets attached to a bus. Note that currently all usb1 emulated device claim to be fullspeed, this seems to not cause any problems, but still seems wrong, because with real hardware keyboards, mice and tablets usually are lo-speed, so reporting these as fullspeed devices seems wrong.

2011-06-14usb-ccid: Plug memory leak on qdev exit()Markus Armbruster1-20/+8
ccid_initfn() allocates CCIDBus dynamically, but there is no exit callback to free it. Fix by getting rid of the allocation. Signed-off-by: Markus Armbruster <armbru@redhat.com>
2011-05-26usb: Pass the packet to the device's handle_control callbackHans de Goede1-2/+2
This allows using the generic usb_generic_handle_packet function from device code which does ASYNC control requests (such as the linux host pass through code). Signed-off-by: Hans de Goede <hdegoede@redhat.com>
2011-04-07usb-ccid: Spelling fixesBrad Hards1-4/+4
While looking at David Gibson's build-fix for hw/usb-ccid.c, I noticed a spello in a comment on the following (unchanged) line. Signed-off-by: Brad Hards <bradh@frogmouth.net> Signed-off-by: Stefan Hajnoczi <stefanha@linux.vnet.ibm.com>
2011-04-04Fix non-portable format string in usb-ccid.cDavid Gibson1-1/+1
At one point, usb-ccid.c attempts to use a %lX format specifier to print a uint64_t, which is only correct on some host platforms. This patch corrects the statement to use the stdint specified PRIX64 constant instead. Signed-off-by: David Gibson <david@gibson.dropbear.id.au> Signed-off-by: Aurelien Jarno <aurelien@aurel32.net>
2011-04-01usb-ccid: add CCID busAlon Levy1-0/+1419
A CCID device is a smart card reader. It is a USB device, defined at [1]. This patch introduces the usb-ccid device that is a ccid bus. Next patches will introduce two card types to use it, a passthru card and an emulated card. [1] http://www.usb.org/developers/devclass_docs/DWG_Smart-Card_CCID_Rev110. Signed-off-by: Alon Levy <alevy@redhat.com> --- changes from v20->v21: (Jes Sorenson review) * cosmetic changes - fix multi line comments. * reorder fields in USBCCIDState * add reference to COPYING * add --enable-smartcard and --disable-smartcard here (moved from last patch) changes from v19->v20: * checkpatch.pl changes from v18->v19: * merged: ccid.h: add copyright, fix define and remove non C89 comments * add qdev.desc changes from v15->v16: Behavioral changes: * fix abort on client answer after card remove * enable migration * remove side affect code from asserts * return consistent self-powered state * mask out reserved bits in ccid_set_parameters * add missing abRFU in SetParameters (no affect on linux guest) whitefixes / comments / consts defines: * remove stale comment * remove ccid_print_pending_answers if no DEBUG_CCID * replace printf's with DPRINTF, remove DEBUG_CCID, add verbosity defines * use error_report * update copyright (most of the code is not original) * reword known bug comment * add missing closing quote in comment * add missing whitespace on one line * s/CCID_SetParameter/CCID_SetParameters/ * add comments * use define for max packet size Comment for "return consistent self-powered state": the Configuration Descriptor bmAttributes claims we are self powered, but we were returning not self powered to USB_REQ_GET_STATUS control message. In practice, this message is not sent by a linux 2.6.35.10-74.fc14.x86_64 guest (not tested on other guests), unless you issue lsusb -v as root (for example).
