Sparc32 keyboard — QEMU documentation

# Sparc32 keyboard

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.

With the escc.chnA-sunkbd-layout driver property it is possible to select keyboard layout. Example:

-global escc.chnA-sunkbd-layout=de

Depending on type of keyboard, the keyboard can have 6 or 5 dip-switches to select keyboard layout, giving up to 64 different layouts. Not all combinations are supported by Solaris and even less by Sun OpenBoot BIOS.

The dip switch settings can be given as hexadecimal number, decimal number or in some cases as a language string. Examples:

-global escc.chnA-sunkbd-layout=0x2b

-global escc.chnA-sunkbd-layout=43

-global escc.chnA-sunkbd-layout=sv

The above 3 examples all select a swedish keyboard layout. Table 3-15 at https://docs.oracle.com/cd/E19683-01/806-6642/new-43/index.html explains which keytable file is used for different dip switch settings. The information in that table can be summarized in this table:

Language selection values for escc.chnA-sunkbd-layout
Hexadecimal value | Decimal value | Language code
--- | --- | ---
0x21 | 33 | en-us
0x23 | 35 | fr
0x24 | 36 | da
0x25 | 37 | de
0x26 | 38 | it
0x27 | 39 | nl
0x28 | 40 | no
0x29 | 41 | pt
0x2a | 42 | es
0x2b | 43 | sv
0x2c | 44 | fr-ch
0x2d | 45 | de-ch
0x2e | 46 | en-gb
0x2f | 47 | ko
0x30 | 48 | tw
0x31 | 49 | ja
0x32 | 50 | fr-ca
0x33 | 51 | hu
0x34 | 52 | pl
0x35 | 53 | cz
0x36 | 54 | ru
0x37 | 55 | lv
0x38 | 56 | tr
0x39 | 57 | gr
0x3a | 58 | ar
0x3b | 59 | lt
0x3c | 60 | nl-be
0x3c | 60 | be

Not all dip switch values have a corresponding language code and both “be” and “nl-be” correspond to the same dip switch value. By default, if no value is given to escc.chnA-sunkbd-layout 0x21 (en-us) will be used.
