Hervé Poussineau	ec044a80e7	ps2: do not generate invalid key codes for unknown keys Instead, print a warning message. Signed-off-by: Hervé Poussineau <hpoussin@reactos.org> Message-id: 1473969987-5890-6-git-send-email-hpoussin@reactos.org Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>	2016-09-28 14:03:42 +02:00
Hervé Poussineau	8c10e0baf0	ps2: use QEMU qcodes instead of scancodes 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 Reference: http://www.computer-engineering.org/ps2keyboard/scancodes1.html http://www.computer-engineering.org/ps2keyboard/scancodes2.html http://www.computer-engineering.org/ps2keyboard/scancodes3.html Signed-off-by: Hervé Poussineau <hpoussin@reactos.org> Message-id: 1473969987-5890-5-git-send-email-hpoussin@reactos.org Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>	2016-09-28 14:03:42 +02:00
Hervé Poussineau	57d5c005d3	ps2: allow keycode translation for all scancode sets 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.

Hervé Poussineau	4df23b64c5	ps2: correctly handle 'get/set scancode' command When getting scancode, current scancode must be preceded from reply ack. When setting scancode, we must reject invalid scancodes.
