* usb-serial: implement break event.Jason Wessel2009-05-221-2/+10
| | | | | | | | | | | | | | 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>

* Implement "info chardev" command. (Gerd Hoffmann)aliguori2008-10-311-1/+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
