ir-keytable question [Ubuntu 17.04]

[Szabolcs Andrasi]

Hi,

I'm using Ubuntu 17.04 and I installed the ir-keytable tool. The
output of the ir-keytable command is as follows:



Found /sys/class/rc/rc0/ (/dev/input/event5) with:
Driver ite-cir, table rc-rc6-mce
Supported protocols: unknown other lirc rc-5 rc-5-sz jvc sony nec
sanyo mce_kbd rc-6 sharp xmp
Enabled protocols: lirc rc-6
Name: ITE8708 CIR transceiver
bus: 25, vendor/product: 1283:0000, version: 0x0000
Repeat delay = 500 ms, repeat period = 125 ms



I'm trying to enable the supported mce_kbd protocol in addition to the
lirc and rc-6 protocols with the

$ sudo ir-keytable -p lirc -p rc-6 -p mce_kbd

command which works as expected. If, however, I reboot my computer,
ir-keytable forgets this change and only the lirc and rc-6 protocols
are enabled. Is there a configuration file I can edit so that after
the boot my IR remote still works? Or is that so that the only way to
make it work is to write a start-up script that runs the above command
to enable the needed protocol?

Thank you in advance!

So what we have today is /etc/rc_maps.cfg, where you can select the default
keymap for a particular driver; unfortunately, you can only select one
keymap and one keymap can only have one protocol.

Ideally we could either have more than one protocol per keymap, which
would be helpful for the MCE Keyboard, or we could allow multiple keymaps
which would be great for supporting different remotes at the same time.

For now, you could add a udev rule to also enable the mce_kbd protocol.

Having more than one protocol in the keymap file works fine here,
we have been using that feature in LibreELEC for a long time now.
Maybe it was just forgotten to document it?

    ir-keytable: add support for more than one protocol in a table

    Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>

Quick test with ir-keytable 1.12.3 from Debian Stretch:

$ sudo ir-keytable -c -p lirc,rc-6 -s rc1
Old keytable cleared
Protocols changed to lirc rc-6

$ sudo ir-keytable -r -s rc1
Enabled protocols: lirc rc-6

$ cat /etc/rc_keymaps/rc6_mce_kbd_test
# table test, type:rc-6,mce_kbd
0x01    KEY_1

$ cat test-map.cfg
* * rc6_mce_kbd_test

$ sudo ir-keytable -a test-map.cfg -s rc1
Old keytable cleared
Wrote 1 keycode(s) to driver
Protocols changed to mce_kbd rc-6

$ sudo ir-keytable -r -s rc1
scancode 0x0001 = KEY_1 (0x02)
Enabled protocols: lirc mce_kbd rc-6

so long,

-snip-

Yes, you're right. I was wrong.

So, first of all, in recent kernels the "lirc" protocol is always enabled
and cannot be disabled. So there is no reason to explicitly enable it.

Now if you want to enable both rc-6 and mce_kbd, is that because you want
to use the Microsoft MCE IR keyboard? It uses both rc-6 and mce_kbd
protocol.

We should really have a keymap for this device; the only difference
with the rc6_mce keyboard is that mce_kbd protocol is also used.

Would that work?
