[Qemu-devel] [PATCH] Keyboard portability

[Qemu-devel] [PATCH] Keyboard portability

[Chris Emerson]

[-- Attachment #1: Type: text/plain, Size: 345 bytes --]

Here's a patch which makes the keyboard usable for me on Debian/PPC.
The translation to PC keycodes is done from the SDL keysym rather than
the original scancode.  It's likely that there could be problems with
different keyboard layouts, but I think it should work on the whole.

Not tested on anything but my PowerMac with USB keyboard.
