ir-keytable: infinite loops, segfaults

Hi,

I have a fairly old dvico dual digital 4 tuner and remote. There seem to be some issues with support for it, can I help fix them?

I am using ir-keytable 1.10.0-1 on Ubuntu 16.04 LTS, with kernel 4.4.0-47-generic (package version 4.4.0-47-generic)

The remote's keymapping is the one in /lib/udev/rc_keymaps/dvico_mce; kernel support for the device is in media/usb/dvb-usb/cxusb.c.

Mostly it works, in that I get correct keycodes back from evtest and ir-keytable -t. But I want to change some of the keycode mappings and that is not working.

  # cat >testfile
  0xfe47 KEY_PAUSE
  ^D

  # ir-keytable -v -d /dev/input/event15 -w testfile
  Parsing testfile keycode file
  parsing 0xfe47=KEY_PAUSE:   value=119
  Opening /dev/input/event15
  Input Protocol version: 0x00010001
      fe47=0077
  Wrote 1 keycode(s) to driver

So far so good, yes? But evtest still reports the same keycode for the key I tried to modify.

  # evtest
  <select device 15>
  <press PLAYPAUSE key on remote>
  Event: time 1479206112.262746, type 1 (EV_KEY), code 164 (KEY_PLAYPAUSE), value 1

  Enabled protocols: unknown rc-5 sony nec sanyo mce-kbd rc-6 sharp xmp 
  scancode 0xfe02 = KEY_PAUSE (0x77)
  scancode 0xfe47 = KEY_PLAYPAUSE (0xa4)

I thought that I might need to clear and replace the entire table to get things working. This is where the problems really start.

First trying to clear the table causes an infinite loop.

  Deleting entry 2114690
  ^C

Then I tried to load a modified version of dvico_mce The whole file was there, with just this change:

The program seems to parse the modified file ok but then segaults while reading from the input device.

PS evtest reports this about the device:

I suspect the problem here is rc-core is not used and legacy_dvb_usb_setkeycode has a bug (it has several problems).

It would be nicer if we could move it rc-core, but for that to work we need to know what scancodes remote sends (and in what protocol). A scancode of 0xfe47 is not a valid RC5 scancode.

Would it be possible to test the remote with another device (say an usb mce receiver or so) and see what scancodes it sends? Then we can translate the keymap to a real one and make the cxusb driver send correct scancodes to rc-core.

So are you saying that the hex codes in the rc_map_dvico_mce_table struct are invalid (at least in some cases)?

How can I tell what protocol is in use?
0x00010001 doesn't mean much to me; I did search the linux source for the code but didn't find any helpful matches.

Great idea. Do you mean something like [1]?
Or the (presumably generic) receiver that comes with [2]? Would a FLIRC work?

Probably dumb question - in this machine I also have an iMon Remote (152c:ffdc)
and Leadtek WinFast DTV Dongle Dual
Do you think either of those would be helpful? I tried evtest with them and the remote, no responses.

Most likely the remote produces IR in a standard protocol (e.g. rc5, rc6). If we first get the keymap right then the remote can be used with any IR receiver that can deal with its protocol; conversely, if we know what protocol the IR receiver can receive, and we make it produce the scancodes in the right format, it can then be used with any remote that uses the protocol it understands.

So at the moment we don't know what protocol it is, and even if it is rc5 then some bit shifting might be needed to make it into a proper rc5 scancode (both driver and keymap).

At the moment it's not easy to determine what protocol an remote uses; I would like to change that but for now, the following is probably the easiest way.

cd /sys/class/rc/rc1 # replace rc1 with your receiver for i in $(<protocols); do echo +$i > protocols; done echo 3 > /sys/module/rc_core/parameters/debug journal -f -k

Protocol numbers are defined in enum rc_type, see include/media/rc-map.h

Yes, it would be a receiver like that.

It's not clear what usb receiver it uses.

I hadn't heard of flirc, looks like it doesn't have a kernel driver. Maybe I'll go and get one. :)

Looks like it's neither rc6 nor nec then.

If you don't have the right receiver then all of this a bit academic. Maybe it's possible to port to rc-core with the existing scancodes.

Thanks
Sean

Ah. Here we have a problem. The device (/dev/input/event15) doesn't have a corresponding rcX node, see ir-keytable output below. I had it explained to me like this:

A "HID" device is basically any input device that resembles a keyboard or mouse (Human Interface Device). The label may also cover things like joysticks, etc. It does /not/ include remotes, so it seems, since "remote" can cover a wide variety of input devices.

Some remotes can emulate fully or partially keyboard keypresses which is why they can be treated as HID devices. Of course, not all the keys may be mapped correctly or at all.

I may have given bad information here - I need to check whether the IR receivers for these devices are properly connected. That might be why there was no response...

Thanks for your help so far
Vince

As I said you would need to use a raw IR receiver which has rc-core support to determine the protocol, so never mind. Please can you try this patch:

I don't have the hardware to test this so your input would be appreciated.

Thanks for this. I have got it to build within the media_build setup but will need to find some windows in the schedule for testing. More in a couple of days. Are there specific things you would like me to test?

Vince

You should have an rc device for the IR receiver in the dvb device; does it continue to work and can you clear/load a new keymap with ir-keytable, and does it work after that.

A "Tested-by" would be great if it all works of course.

Thanks
Sean

Wrote 45 keycode(s) to driver
/sys/class/rc/rc1//protocols: Invalid argument
Couldn't change the IR protocols
#

Same result if I add -p RC-6 to the argument list.

Cheers
Vince

That's a mistake, I've fixed that now.

That's also been fixed.

Well, it's unknown because we don't know what protocol the remote and the receiver use.

Well, that won't work as the protocol can't be changed -- it's unknown.

The attached version should fix the driver name problem and the problem of scancode 0 appearing without anything being pressed.

Thanks for testing!

Ah. I see the added module_name struct members.

yep, works nicely.

Things are looking much better!
As shown below I am able to clear a keytable and put in a fresh one. Having a bit of trouble with key remapping.
I guess we still have to work out the protocol in use.

Mapping KEY_OK to KEY_ENTER worked (ie the behaviour when the OK key was pressed changed), but others did not. For example I mapped KEY_BACK (0x9e, decimal 158) to KEY_ESC (001) and KEY_PLAYPAUSE (0xa4, 164) to KEY_PAUSE (119).
But I did not observe any change in behaviour for these two. ir-keytable -t did show the correct KEY_foo and descimal code, eg.

# ir-keytable -s rc1 -t

I notice that KEY_ENTER existed in the original keymap but _PAUSE and _ESC don't, but I don't understand the significance of that.

Vince

That all looks fine.

So if I understand you correctly, if you change the keymap, like you changed 0xfe47 to KEY_PAUSE, then "ir-keytable -s rc1 -t" show you the correct (new) key? So as far as ir-keytable is concerned, everything works?

However when you try to use the new mapping in some application then it does not work?

I don't know how that should matter.

Thanks
Sean

That's correct. ir-keytable seems to be doing the right thing, mapping the scancode to the input-event-codes.h key code I asked it to.

The application I am trying to use it with is the mythtv frontend. I am doing the keycode munging from an SSH session while myth is still running on the main screen. I didn't think this would matter (since it worked for KEY_OK->KEY_ENTER) but perhaps it does. Obviously ir-keytable -t intercepts the scancodes when it is running, but when I kill it myth responds normally to some keys, but not all.

I wanted to mention that the IR protocol is still showing as unknown. Is there anything that can be done to sort that out?

Vince

It turned out that that I had to restart X to make it notice the updated keymap. After that, the modfied keymap I set up is mostly working.

There is still a bit of a mystery. As I understand it, X should notice key codes less than 255 (0xff). But it seems to be ignoring KEY_STOP (code 128, 0x80) and any key codes higher than that but less than 255. ir-keytable -t shows the right codes.

Vince

ir-keytable reads from the input layer, so that's the key being sent. The problem is elsewhere.

X and keycodes is a bit messy. You might need xmodmap mappings. You can check them xev. I don't know much about this, I'm afraid. What linux distribution, version and keyboard layout are you using? I could try and see if I can reproduce/fix this.

It would be nice if that could be sorted out, although that would be a separate patch.

So all we know right now is what scancode the IR receiver hardware produces but we have no idea what IR protocol is being used. In order to figure this out we need a recording of the IR the remote sends, for which a different IR receiver is needed. Neither your imon nor your dvb_usb_af9035 can do this, something like a mce usb IR receiver would be best. Do you have access to one? One with an IR emitter would be best.

So with that we can have a recording of the IR the remote sends, and with the emitter we can see which IR protocols the IR receiver understands.

Sean

I mostly figured this out but something weird happens with the most significant bit (see my follow-on email). FWIW, this is on ubuntu 16.04 with their standard kernel (4.4) and a bog-standard US english layout.

That's fine. For the current patch, please feel free to add my

I'll poke around to see if I can find something, will take a few days. Thanks again for your interest in this.
Vince

Haven't been able to find anything suitable. I would order something but I won't be able to follow up for several weeks.
I'll ask on the myth list to see if anyone is up for trying this.

Thanks again for your help with this
Vince

Hey there

I bought one of these, but I am not sure how to make the recording:

Poking around I see lirc has an irrecord program. Is that what I need?

Hi Vincent,

-snip-

That's great. There are a couple of ways of doing this, and none of them is straightforward. It's a bit of reading tea leaves (that's one of the motivations for my lirc-scancodes patches, but I digress).

Method 1:
echo "+rc-5 +nec +rc-6 +jvc +sony +rc-5-sz +sanyo +sharp +xmp" > /sys/class/rc/rc3/protocols echo 1 > /sys/module/rc_core/parameters/debug
journal -f -k

# press button on remote

Now look for "scancode" somewhere in there.

Method 2:
Either use lirc's mode2 or "ir-ctl -r -d /dev/lircX" (from v4l-utils 1.12), and post the output here.

Thanks!

Sean

I tried your patch, after disabling the custom keymap file I had put in. Unfortunately the remote isn't working at all. When the relevant modules get loaded I see this in dmesg

The dmesg...

Hi Vincent,

Thanks for testing this.

On the cxusb the protocol is now nec, and that is the only protocol it supports, you can't change it.

That is expected. Does the the keymap actually work?

ir-keytable -r -t

Thanks,

Sean

...

doh! ok well that's all good then.

Kind of important information, yes. Answer: not sure. I can see it receiving something but none of the keys I pressed caused any reaction on the application (mythtv)

All the above was done with the system booted with this in /etc/rc.local /usr/bin/ir-keytable -s rc1 -c

After I disabled the rc.local script and rebooted:

nec

When I try to enable the nec protocol I get this:

# ir-keytable  -d /dev/input/event15 -p nec -t -r
Invalid protocols selected
Couldn't change the IR protocols

Hopefully all this stumbling in the dark is somewhat informative... Vince

So it's still using the old keymap. I've attached a new one.

Oops, that's a bug. 0xffff should be 0x0000. I've attached a new version of the patch which should fix that.

From: Sean Young <[email protected]>
Subject: [PATCH] [media] cxusb: dvico remotes are nec

Adjust the keymap to use the correct nec scancodes, and adjust the rc driver to output the correct nec scancodes.

Now the keymap can be used with any nec receiver, and the rc device should work with any nec keymap.

That works, thanks.

I am still getting the high bits set. I checked the code and the patch was correctly applied,
I see where you are applying a 0xff mask to the ircode values.

Sorry Vincent, but are you sure you're running the patch with the & 0xff mask? That should have solved it.

Sean

er, no. Some kind of build issue. Once I applied your media_build patch and then the latest kernel patch you sent, this is what the test run looks like.

So it's working, although ir-keytable seems a little confused about the protocol being used.

I explored other keys and found that higher keycodes are still being ignored by mythtv, e.g.

KEY_BACK(0x009e) scancode 0x149
KEY_MENU(0x008b) scancode 0x14d
KEY_STOP(0x0080) scancode 0x10d

The boundary seems to be 0x0080, all the keycodes below that seem to work. I have not explored messing about with keytable remapping.

But for this patch at least: Tested-By: [email protected] And thanks!

So I checked on the ir receivers and found the rc1 device ir receiver was indeed blocked (haven't checked rc0 properly, time is short)

I tested it with evtest and the remote that comes with the device

I tried to load a keymap but got another segfault

# ir-keytable -p nec -d /dev/input/event16 -w /lib/udev/rc_keymaps/rc6_mce 
Read rc6_mce table
Wrote 63 keycode(s) to driver
Segmentation fault (core dumped)

Can't find a -dbg package so can't give you a useful backtrace at the moment.

Anyway: trying the same evtest with the dvico remote
evtest /dev/input/event16
<volumedown>
Event: time 1479509251.174361, type 4 (EV_MSC), code 4 (MSC_SCAN), value 105

So something is connecting via IR.
Out of time now, more later

I tried this with the rc1 device as a test. I get this odd result:

# cat protocols
nec
# echo '+nec' > protocols
bash: echo: write error: Invalid argument

and ir-keytable still shows no protocols enabled

# ir-keytable

I messed around some more with ir-keytable and got more segfaults if I try to use the -d argument.

-s at least doesn't segfault, but doesn't advance the cause.
