v2 cover ps2: fix keyboard set 3 and misc improvements

Hi,

This patchset is a welcome cleanup of scancodes used in PS/2 keyboard emulation.

- Patches 1 and 2 are fixes to let Linux use set 3 if instructed so.
- Patch 3 makes scancodes untranslated by default and translates them if required, instead of receiving translated scancodes by default and untranslating them if required.
- Patch 4 switches to use qcodes instead of scancodes.
- Patch 5 is a small cleanup, to prevent sending invalid keycodes to the OS.

See each patch commit for details about what changed.

Missing part are handling of following commands in set 3:
- 0xf7: set all keys to typematic/autorepeat only
- 0xf8: set all keys to make/release
- 0xf9: set all keys to make only
- 0xfa: set all keys to typematic/autorepeat make/release
- 0xfb: set specific key to typematic/autorepeat only
- 0xfc: set specific key to make/release
- 0xfd: set specific key to make only

Translated set 2 and untranslated sets 2 and 3 have been tested with Linux, using kernel parameters "i8042.direct=1" and "atkbd.set=3".
Set 1 has been tested with MIPS Magnum emulation.

Patch 4 doesn't pass checkpatch.pl, due to some key mappings not implemented because of missing an equivalent qcode.

Changes since v1:
- fix checkpatch.pl warning (patch 3)
- fix compilation with mingw (patch 5)

Hervé

Hervé Poussineau (5):
ps2: reject unknown commands, instead of blindly accepting them
ps2: correctly handle 'get/set scancode' command
ps2: allow keycode translation for all scancode sets
ps2: use QEMU qcodes instead of scancodes
ps2: do not generate invalid key codes for unknown keys

PATCH v2 2/5 ps2: correctly handle 'get/set scancode' command

In reply to Hervé Poussineau

When getting scancode, current scancode must be preceded from reply ack. When setting scancode, we must reject invalid scancodes.

PATCH v2 3/5 ps2: allow keycode translation for all scancode sets

In reply to Hervé Poussineau

Change ps2_put_keycode to get an untranslated scancode, which is translated if needed.

As qemu_input_key_value_to_scancode() gives translated scancodes, untranslate them in ps2_keyboard_event first before giving them to ps2_put_keycode.

Results are not changed, except for some keys in translated set 3.

Translation table is available at
https://www.win.tue.nl/~aeb/linux/kbd/scancodes-10.html

PATCH v2 4/5 ps2: use QEMU qcodes instead of scancodes

In reply to Hervé Poussineau

This fixes problems with translated set 1, where most make code were wrong. This fixes problems with set 3 for extended keys (like arrows) and lot of other keys. Added a FIXME for set 3, where most keys must not (by default) deliver a break code.

Detailed list of changes on untranslated set 2:
- change of ALTGR break code from 0xe4 to 0xf0 0x08
- change of ALTGR_R break code from 0xe0 0xe4 to 0xe0 0xf0 0x08
- change of F7 make code from 0x02 to 0x83
- change of F7 break code from 0xf0 0x02 to 0xf0 0x83
- change of PRINT make code from 0xe0 0x7c to 0xe0 0x12 0xe0 0x7c
- change of PRINT break code from 0xe0 0xf0 0x7c to 0xe0 0xf0 0x7c 0xe0 0xf0 0x12
- change of PAUSE key: new make code = old make code + old break code, no more break code
- change on RO break code from 0xf3 to 0xf0 0x51
- change on KP_COMMA break code from 0xfe to 0xf0 0x6d

Detailed list of changes on translated set 2 (the most commonly used):
- change of PRINT make code from 0xe0 0x37 to 0xe0 0x2a 0xe0 0x37
- change of PRINT break code from 0xe0 0xb7 to 0xe0 0xb7 0xe0 0xaa
- change of PAUSE key: new make code = old make code + old break code, no more break code
