2012-02-27usb: Resolve warnings about unassigned bus on usb device creationJan Kiszka1-4/+4
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 Färber1-2/+3
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 Hoffmann1-1/+1
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.

2012-02-10usb: kill handle_packet callbackGerd Hoffmann1-2/+0
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 Liguori1-20/+28
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>

2011-08-04usb: use iovecs in USBPacketGerd Hoffmann1-2/+3
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 USB_REQ_{GET,SET}_CONFIGURATION handling to common codeGerd Hoffmann1-8/+2
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>

2011-01-11usb serial: use new descriptor infrastructure.Gerd Hoffmann1-117/+83
Switch the usb serial drivers (serial, braille) over to the new descriptor infrastructure. Note that this removes the freely configurable vendor and product id properties. I think the only reason this was configurable is that the only difference between the serial and the braille device is the vendor+product id. Of course the serial and braille devices keep their different IDs, but they can't be overritten from the command line any more. Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>

error_report() terminates the message with a newline. Strip it it from its arguments. This fixes a few error messages lacking a newline: net_handle_fd_param()'s "No file descriptor named %s found", and tap_open()'s "vnet_hdr=1 requested, but no kernel support for IFF_VNET_HDR available" (all three versions). There's one place that passes arguments without newlines intentionally: load_vmstate(). Fix it up.

2010-02-10segfault due to buffer overrun in usb-serialDavid S. Ahern1-6/+22
This fixes a segfault due to buffer overrun in the usb-serial device. The memcpy was incrementing the start location by recv_used yet, the computation of first_size (how much to write at the end of the buffer before wrapping to the front) was not accounting for it. This causes the next element after the receive buffer (recv_ptr) to get overwritten with random data.

Implement the serial break via usb serial. The second data byte in ftdi status packet contains the break status. The values were already defined in usb-serial.c so it was a matter of making use of the event_trigger to form a urb to send over to the host controller with the serial break status set. This was tested against a linux development image which enables sysrq via a serial break on the ftdi usb console. Signed-off-by: Jason Wessel <jason.wessel@windriver.com>

2008-10-31Implement "info chardev" command. (Gerd Hoffmann)aliguori1-1/+4
This patch makes qemu keep track of the character devices in use and implements a "info chardev" monitor command to print a list. qemu_chr_open() sticks the devices into a linked list now. It got a new argument (label), so there is a name for each device. It also assigns a filename to each character device. By default it just copyes the filename passed in. Individual drivers can fill in something else though. qemu_chr_open_pty() sets the filename to name of the pseudo tty allocated. Output looks like this: (qemu) info chardev monitor: filename=unix:/tmp/run.sh-26827/monitor,server,nowait serial0: filename=unix:/tmp/run.sh-26827/console,server serial1: filename=pty:/dev/pts/5 parallel0: filename=vc:640x480 Signed-off-by: Gerd Hoffmann <kraxel@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com> git-svn-id: svn://svn.savannah.nongnu.org/qemu/trunk@5575 c046a42c-6fe2-441c-8c8c-71466251a162
