From 6b90a4cdc04ec7ca94c3f664d63ee43c2046a875 Mon Sep 17 00:00:00 2001 From: Henrik Carlqvist Date: Fri, 23 Jun 2023 20:30:07 +0200 Subject: escc: emulate dip switch language layout settings on SUN keyboard MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit 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 https://docs.oracle.com/cd/E19683-01/806-6642/new-43/index.html 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 applied.
