    escc: emulate dip switch language layout settings on SUN keyboard · 6b90a4cd
    Henrik Carlqvist authored and Mark Cave-Ayland's avatar Mark Cave-Ayland committed
    SUN Type 4, 5 and 5c keyboards have dip switches to choose the language layout
    of the keyboard. Solaris makes an ioctl to query the value of the dipswitches
    and uses that value to select keyboard layout.  Also the SUN bios like the one
    in the file ss5.bin uses this value to support at least some keyboard layouts.
    However, the OpenBIOS provided with qemu is hardcoded to always use an US
    keyboard layout.
    Before this patch, qemu allways gave dip switch value 0x21 (US keyboard),
    this patch uses a command line switch like
    "-global escc.chnA-sunkbd-layout=de" to select dip switch value. A table is
    used to lookup values from arguments like:
    -global escc.chnA-sunkbd-layout=fr
    -global escc.chnA-sunkbd-layout=es
    But the patch also accepts numeric dip switch values directly:
    -global escc.chnA-sunkbd-layout=0x2b
    -global escc.chnA-sunkbd-layout=43
    Both values above are the same and select swedish keyboard as explained in
    table 3-15 at
    Unless you want to do a full Solaris installation but happen to have
    access to a Sun bios file, the easiest way to test that the patch works
    is to:
    qemu-system-sparc -global escc.chnA-sunkbd-layout=sv -bios /path/to/ss5.bin
    If you already happen to have a Solaris installation in a qemu disk image
    file you can easily try different keyboard layouts after this patch is
