2012-02-27usb: Resolve warnings about unassigned bus on usb device creationJan Kiszka
When creating an USB device the old way, there is no way to specify the target bus. Thus the warning issued by usb_create makes no sense and rather confuses our users. Resolve this by passing a bus reference to the usbdevice_init handler and letting those handlers forward it to usb_create.

2012-02-15qom: Unify type registrationAndreas Färber
Replace device_init() with generalized type_init(). While at it, unify naming convention: type_init([$prefix_]register_types) Also, type_init() is a function, so add preceding blank line where necessary and don't put a semicolon after the closing brace.

2012-02-10usb: Set USBEndpoint in usb_packet_setup().Gerd Hoffmann
With the separation of the device lookup (via usb_find_device) and packet processing we can lookup device and endpoint before setting up the usb packet. So we can initialize USBPacket->ep early and keep it valid for the whole lifecycle of the USBPacket. Also the devaddr and devep fields are not needed any more. Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>
2012-02-10usb: kill handle_packet callbackGerd Hoffmann
All drivers except usb-hub use usb_generic_handle_packet. The only reason the usb hub has its own function is that it used to be called with packets which are intended for downstream devices. With the new, separate device lookup step this doesn't happen any more, so the need for a different handle_packet callback is gone. So we can kill the handle_packet callback and just call usb_generic_handle_packet directly. The special hub handling in usb_handle_packet() can go away for the same reason.

2012-02-03qdev: register all types natively through QEMU Object ModelAnthony Liguori
This was done in a mostly automated fashion. I did it in three steps and then rebased it into a single step which avoids repeatedly touching every file in the tree. The first step was a sed-based addition of the parent type to the subclass registration functions. The second step was another sed-based removal of subclass registration functions while also adding virtual functions from the base class into a class_init function as appropriate. Finally, a python script was used to convert the DeviceInfo structures and qdev_register_subclass functions to TypeInfo structures, class_init functions, and type_register_static calls. We are almost fully converted to QOM after this commit. Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>

2012-01-27qdev: move qdev->info to classAnthony Liguori
Right now, DeviceInfo acts as the class for qdev. In order to switch to a proper ObjectClass derivative, we need to ween all of the callers off of interacting directly with the info pointer. Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2012-01-13usb: add audio device modelH. Peter Anvin
This brings a usb audio device to qemu. Output only, fixed at 16bit stereo @ 480000 Hz. Based on a patch from H. Peter Anvin <hpa@linux.intel.com> Usage: add '-device usb-audio' to your qemu command line. Works sorta ok on a idle machine. Known issues: * Is *very* sensitive to latencies. * Burns quite some CPU due to usb polling. In short: It brings the qemu usb emulation to its limits. Enjoy!

2011-08-04usb: use iovecs in USBPacketGerd Hoffmann
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>

2011-01-11usb: move remote wakeup handling to common codeGerd Hoffmann

2011-01-11usb: move USB_REQ_{GET,SET}_CONFIGURATION handling to common codeGerd Hoffmann
This patch adds fields to the USBDevice struct for the current speed (hard-wired to full speed for now) and current device configuration. Also a init function is added which inializes these fields. This allows USB_REQ_{GET,SET}_CONFIGURATION handling to be moved to common code. For most drivers the conversion is trivial ad they support a single configuration only anyway. One exception is bluetooth where some device-specific setup code runs after get/set configuration. The other is usb-net which actually has two configurations so the the code to check for the active configuration has been adapted. Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>

2010-03-31usb: class specific interface requestsMax Reitz
Mass Storage Reset and Get Max LUN are class specific requests, but they were not marked as such in hw/usb-msd.c, moved therefore ClassInterfaceRequest and ClassInterfaceOutRequest from hw/usb-net.c to hw/usb.h. Furthermore there was a problem in hw/usb-ohci.c when using DEBUG concerning systems where size_t is a 32 bit integer (printf resulted in a segmentation fault).

2010-03-16qemu-option: Move the implied first name into QemuOptsListMarkus Armbruster
We sometimes permit omitting the first option name, for example -device foo is short for -device driver=foo. The name to use ("driver" in the example) is passed as argument to qemu_opts_parse(). For each QemuOptsList, we use at most one such name. Move the name into QemuOptsList, and pass whether to permit the abbreviation. This ensures continued consistency, and simplifies the commit after next in this series.
2010-02-25Fix -usbdevice crashPaul Brook

2010-01-19Fix QEMU_WARN_UNUSED_RESULTKevin Wolf
Since commit 747bbdf7 QEMU_WARN_UNUSED_RESULT is never defined as it is conditional on a define from config-host.h which is included only later. Include that file earlier to get the warnings back. Reactivating it unfortunately leads to some warnings about unused qdev_init results. These calls are changed to qdev_init_nofail to avoid build failures.

2009-09-12Fix sys-queue.h conflict for goodBlue Swirl
Problem: Our file sys-queue.h is a copy of the BSD file, but there are some additions and it's not entirely compatible. Because of that, there have been conflicts with system headers on BSD systems. Some hacks have been introduced in the commits 15cc9235840a22c289edbe064a9b3c19c5f49896, f40d753718c72693c5f520f0d9899f6e50395e94, 96555a96d724016e13190b28cffa3bc929ac60dc and 3990d09adf4463eca200ad964cc55643c33feb50 but the fixes were fragile. Solution: Avoid the conflict entirely by renaming the functions and the file. Revert the previous hacks. Signed-off-by: Blue Swirl <blauwirbel@gmail.com>

destroy_nic() requires that NICInfo::private by a PCIDevice pointer, but then goes on to require that the same pointer matches VLANClientState::opaque.
