Implement "info chardev" command. (Gerd Hoffmann)
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
