Example: "MAINPID=4711" - - WATCHDOG=1 Tells systemd to update the watchdog timestamp. - Services using this feature should do this in - regular intervals. A watchdog framework can use the - timestamps to detect failed services. - - Daemons can choose to send additional variables. However, it is - recommended to prefix variable names not listed above with X_. - - Returns a negative errno-style error code on failure. Returns > 0 - if systemd could be notified, 0 if it couldn't possibly because - systemd is not running. - - Example: When a daemon finished starting up, it could issue this - call to notify systemd about it: - - sd_notify(0, "READY=1"); - - See sd_notifyf() for more complete examples. - - See sd_notify(3) for more information. -*/ -int sd_notify(int unset_environment, const char *state); - -/* - Similar to sd_notify() but takes a format string. - - Example 1: A daemon could send the following after initialization: - - sd_notifyf(0, "READY=1\n" - "STATUS=Processing requests...\n" - "MAINPID=%lu", - (unsigned long) getpid()); - - Example 2: A daemon could send the following shortly before - exiting, on failure: - - sd_notifyf(0, "STATUS=Failed to start up: %s\n" - "ERRNO=%i", - strerror(errno), - errno); - - See sd_notifyf(3) for more information. -*/ -int sd_notifyf(int unset_environment, const char *format, ...) _sd_printf_attr_(2,3); - -/* - Returns > 0 if the system was booted with systemd.

This is +particularly necessary for the non-standard extra keys found on many laptops, +such as "brightness up", "next song", "www browser", or "suspend". Often these +are accessed with the Fn key. + +Every key produces a "scan code", which is highly vendor/model specific for the +nonstandard keys. This tool maintains mappings for these scan codes to standard +"key codes", which denote the "meaning" of the key. The key codes are defined +in /usr/include/linux/input.h. + +If some of your keys on your keyboard are not working at all, or produce the +wrong effect, then a very likely cause of this is that the scan code -> key +code mapping is incorrect on your computer. + +== Structure == + +udev-keymap consists of the following parts: + + keymaps/*:: mappings of scan codes to key code names + + 95-keymap.rules:: udev rules for mapping system vendor/product names and + input module names to one of the keymaps above + + keymap:: manipulate an evdev input device: + * write a key map file into a device (used by udev rules) + * dump current scan → key code mapping + * interactively display scan and key codes of pressed keys + + findkeyboards:: display evdev input devices which belong to actual keyboards, + i. e. those suitable for the keymap program + +== Fixing broken keys == + +In order to make a broken key work on your system and send it back to upstream +for inclusion you need to do the following steps: + + 1. Find the keyboard device. + + Run /usr/lib/udev/findkeyboards. This should always give you an "AT + keyboard" and possibly a "module". Some laptops (notably Thinkpads, Sonys, and + Acers) have multimedia/function keys on a separate input device instead of the + primary keyboard. The keyboard device should have a name like "input/event3". + In the following commands, the name will be written as "input/eventX" (replace + X with the appropriate number). + + 2. Find broken scan codes: + + sudo /usr/lib/udev/keymap -i input/eventX + + Press all multimedia/function keys and check if the key name that gets printed + out is plausible. If it is unknown or wrong, write down the scan code (looks + like "0x1E") and the intended functionality of this key. Look in + /usr/include/linux/input.h for an available KEY_XXXXX constant which most + closely approximates this functionality and write it down as the new key code. + + For example, you might press a key labeled "web browser" which currently + produces "unknown". Note down this: + + 0x1E www # Fn+F2 web browser + + Repeat that for all other keys. Write the resulting list into a file. Look at + /usr/lib/udev/keymaps/ for existing key map files and make sure that you use the + same structure. + + If the key only ever works once and then your keyboard (or the entire desktop) + gets stuck for a long time, then it is likely that the BIOS fails to send a + corresponding "key release" event after the key press event. Please note down + this case as well, as it can be worked around in + /usr/lib/udev/keymaps/95-keyboard-force-release.rules . + + 3. Find out your system vendor and product: + + cat /sys/class/dmi/id/sys_vendor + cat /sys/class/dmi/id/product_name + + 4. Generate a device dump with "udevadm info --export-db > /tmp/udev-db.txt". + + 6. Send the system vendor/product names, the key mapping from step 2, + and /tmp/udev-db.txt from step 4 to the linux-hotplug@vger.kernel.org mailing + list, so that they can be included in the next release. + +For local testing, copy your map file to /usr/lib/udev/keymaps/ with an appropriate +name, and add an appropriate udev rule to /usr/lib/udev/rules.d/95-keymap.rules: + + * If you selected an "AT keyboard", add the rule to the section after + 'LABEL="keyboard_vendorcheck"'. + + * If you selected a "module", add the rule to the top section where the + "ThinkPad Extra Buttons" are. + +== Author == + +keymap is written and maintained by Martin Pitt . diff --git a/src/keymap/check-keymaps.sh b/src/keymap/check-keymaps.sh new file mode 100755 index 0000000000..c4572745e0 --- /dev/null +++ b/src/keymap/check-keymaps.sh @@ -0,0 +1,38 @@ +#!/bin/bash + +# check that all key names in keymaps/* are known in +# and that all key maps listed in the rules are valid and present in +# Makefile.am +SRCDIR=${1:-.} +KEYLIST=${2:-src/udev/keymap/keys.txt} +KEYMAPS_DIR=$SRCDIR/keymaps +RULES=$SRCDIR/src/udev/keymap/95-keymap.rules + +[ -e "$KEYLIST" ] || { + echo "need $KEYLIST please build first" >&2 + exit 1 +} + +missing=$(join -v 2 <(awk '{print tolower(substr($1,5))}' $KEYLIST | sort -u) \ + <(grep -hv '^#' ${KEYMAPS_DIR}/*| awk '{print $2}' | sort -u)) +[ -z "$missing" ] || { + echo "ERROR: unknown key names in keymaps/*:" >&2 + echo "$missing" >&2 + exit 1 +} + +# check that all maps referred to in $RULES exist +maps=$(sed -rn '/keymap \$name/ { s/^.*\$name ([^"[:space:]]+).*$/\1/; p }' $RULES) +for m in $maps; do + # ignore inline mappings + [ "$m" = "${m#0x}" ] || continue + + [ -e ${KEYMAPS_DIR}/$m ] || { + echo "ERROR: unknown map name in $RULES: $m" >&2 + exit 1 + } + grep -q "keymaps/$m\>" $SRCDIR/Makefile.am || { + echo "ERROR: map file $m is not added to Makefile.am" >&2 + exit 1 + } +done diff --git a/src/keymap/findkeyboards b/src/keymap/findkeyboards new file mode 100755 index 0000000000..9ce27429b2 --- /dev/null +++ b/src/keymap/findkeyboards @@ -0,0 +1,68 @@ +#!/bin/sh -e +# Find "real" keyboard devices and print their device path. +# Author: Martin Pitt +# +# Copyright (C) 2009, Canonical Ltd. +# +# This program is free software; you can redistribute it and/or modify it +# under the terms of the GNU General Public License as published by +# the Free Software Foundation; either version 2 of the License, or +# (at your option) any later version. +# +# This program is distributed in the hope that it will be useful, but +# WITHOUT ANY WARRANTY; without even the implied warranty of +# MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

This tool maintains mappings for these scan codes to standard -"key codes", which denote the "meaning" of the key. The key codes are defined -in /usr/include/linux/input.h. - -If some of your keys on your keyboard are not working at all, or produce the -wrong effect, then a very likely cause of this is that the scan code -> key -code mapping is incorrect on your computer. - -== Structure == - -udev-keymap consists of the following parts: - - keymaps/*:: mappings of scan codes to key code names - - 95-keymap.rules:: udev rules for mapping system vendor/product names and - input module names to one of the keymaps above - - keymap:: manipulate an evdev input device: - * write a key map file into a device (used by udev rules) - * dump current scan → key code mapping - * interactively display scan and key codes of pressed keys - - findkeyboards:: display evdev input devices which belong to actual keyboards, - i. e. those suitable for the keymap program - -== Fixing broken keys == - -In order to make a broken key work on your system and send it back to upstream -for inclusion you need to do the following steps: - - 1. Find the keyboard device. - - Run /usr/lib/udev/findkeyboards. This should always give you an "AT - keyboard" and possibly a "module". Some laptops (notably Thinkpads, Sonys, and - Acers) have multimedia/function keys on a separate input device instead of the - primary keyboard. The keyboard device should have a name like "input/event3". - In the following commands, the name will be written as "input/eventX" (replace - X with the appropriate number). - - 2. Find broken scan codes: - - sudo /usr/lib/udev/keymap -i input/eventX - - Press all multimedia/function keys and check if the key name that gets printed - out is plausible. If it is unknown or wrong, write down the scan code (looks - like "0x1E") and the intended functionality of this key. Look in - /usr/include/linux/input.h for an available KEY_XXXXX constant which most - closely approximates this functionality and write it down as the new key code. - - For example, you might press a key labeled "web browser" which currently - produces "unknown". Note down this: - - 0x1E www # Fn+F2 web browser - - Repeat that for all other keys. Write the resulting list into a file. Look at - /usr/lib/udev/keymaps/ for existing key map files and make sure that you use the - same structure. - - If the key only ever works once and then your keyboard (or the entire desktop) - gets stuck for a long time, then it is likely that the BIOS fails to send a - corresponding "key release" event after the key press event. Please note down - this case as well, as it can be worked around in - /usr/lib/udev/keymaps/95-keyboard-force-release.rules . - - 3.
