From 7c388dbd0b2c54b3d836c23ea43e2cee38de66a4 Mon Sep 17 00:00:00 2001 From: "Daniel P. Berrange" Date: Thu, 27 Jul 2017 12:32:43 +0100 Subject: ps2: fix sending of PAUSE/BREAK scancodes MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The processing of the scancodes for PAUSE/BREAK has been broken since the conversion to qcodes in: commit 8c10e0baf0260b59a4e984744462a18016662e3e Author: Hervé Poussineau Date: Thu Sep 15 22:06:26 2016 +0200 ps2: use QEMU qcodes instead of scancodes When using a VNC client, with the raw scancode extension, the client will send a scancode of 0xc6 for both PAUSE and BREAK. There is mistakenly no entry in the qcode_to_number table for this scancode, so ps2_keyboard_event() just generates a log message and discards the scancode When using a SPICE client, it will also send 0xc6 for BREAK, but will send 0xe1 0x1d 0x45 0xe1 0x9d 0xc5 for PAUSE. There is no entry in the qcode_to_number table for the scancode 0xe1 because it is a special XT keyboard prefix not mapping to any QKeyCode. Again ps2_keyboard_event() just generates a log message and discards the scancode. The following 0x1d, 0x45, 0x9d, 0xc5 scancodes get handled correctly. Rather than trying to handle 3 byte sequences of scancodes in the PS/2 driver, special case the SPICE input code so that it captures the 3 byte pause sequence and turns it into a Pause QKeyCode.
