[Qemu-devel] [PATCH 0/2] Qemu support for multiple keyboard devices

[Shahar Havivi]

Qemu support for multiple keyboard devices:

Patch #1 adding keyboard is done to list instead of "last added keyboard 
         wins", when removing keyboard via device_del - next keyboard
         selected.

Patch #2 adding 2 new monitor command to handle keyboard list: 
         'info keyboard' - show all keyboards and mark the current one
         'keyboard_set'  - set active keyboard by index as display in
                           'info keyboard' 
         

Shahar Havivi (2):
  Support for multiple keyboard devices
  Added monitor commands: 'keyboard_set' and 'info keybaord'

[Qemu-devel] [PATCH 1/2] Support for multiple keyboard devices

[Shahar Havivi]

Currently you get segfault when trying to remove keyboard because no
keyboard handling is done.
This patch add keyboard list similar to the mouse device handlers.
Adding a keyboard add to the list, removing keyboard select the next
keyboard in list, and not leaving the keyboard handlers un-handled.

 Please, document the data you return, you can look at do_info_mice()

 keyboard_set is not available under QMP, do you have an special
reason to do so or you have just done like the do_mouse_set()?

 In any case, you should use mhandler.cmd_new as mhandler.cmd is
going to be deprecated (which also means you should use
qerror_report() to report errors).

 Better to resend the whole series with a 'v2' in it, also I think you'll
have to rebase against master because this series conflicts with latest
Anthony's series.

 I have some QError comments below.

 Couldn't you use QERR_DEVICE_NOT_FOUND?

 We're using something like:

qerror_report(QERR_INVALID_PARAMETER, "index");

 For this kind of error.
