2009-12-12qdev: Replace device names containing whitespaceMarkus Armbruster
Device names with whitespace require quoting in the shell and in the monitor. Some of the offenders are also overly long. Some have a more convenient alias, some don't. The place for verbose device names is DeviceInfo member desc. The name should be short & sweet.

2009-12-12qdev: Separate USB product description from qdev nameMarkus Armbruster
Using the qdev name for the product description makes for inconvenient qdev names. Put the product description in new USBDeviceInfo member product_desc. Make usb_qdev_init() use it. No user or guest visible change, since the value is still the same.

2009-10-05usb: hook unplug into qdev, cleanups + fixes.Gerd Hoffmann
Hook into DeviceInfo->exit(). handle_destroy() must not free the state struct, this is handled by the new usb_qdev_exit() function now. qdev_free(usb_device) works now. Fix usb hub to qdev_free() all connected devices on unplug. Unplugging a usb hub works now. Signed-off-by: Gerd Hoffmann <kraxel@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2009-09-09qdev/usb: add usb bus support to qdev, convert drivers.Gerd Hoffmann
* Add USBBus. * Add USBDeviceInfo, move device callbacks here. * Add usb-qdev helper functions. * Switch drivers to qdev.

2009-05-22usb-serial: implement break event.Jason Wessel
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)aliguori
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
2008-09-17[PATCH] usb-serial: Fix data corruption with usb serial emulationaurel32
* Remove the unused send_buf variable and its constant. * Fix a math error The variables recv_ptr and recv_used are not large enough to hold the constant 384, which causes data corruption when the pointer is reset with: s->recv_ptr = (s->recv_ptr + len) % RECV_BUF; Signed-off-by: Jason Wessel <jason.wessel@windriver.com> Acked-by: Samuel Thibault <samuel.thibault@ens-lyon.org> Signed-off-by: Aurelien Jarno <aurelien@aurel32.net> git-svn-id: svn://svn.savannah.nongnu.org/qemu/trunk@5242 c046a42c-6fe2-441c-8c8c-71466251a162
