lirc bug in kernel 4.10-rc1

lirc bug in kernel 4.10-rc1

[Wim Osterholt]

L.S.,

after appearance of kernel-4.10-rc1 two days ago I was pleasantly surprised
to find a question about lirc_serial in 'make oldconfig':

    Homebrew Serial Port Receiver (IR_SERIAL) [N/m/?] (NEW) m
      Serial Port Transmitter (IR_SERIAL_TRANSMITTER) [Y/n/?] y

I was used to 'lirc_serial: module is from the staging directory, the quality
is unknown, you have been warned.'
This always worked perfectly fine with the last working version of lirc: 0.9.0-rc6.
Would things finally get better now?  NO!

In kernel-4.10-rc1 lirc_serial has been removed from staging. It has vanished
completely. If it were only renamed to serial_ir there would be no problem.
I just change the modules parameters
   options lirc_serial irq=4 io=0x3f8 type=0 txsense=0 softcarrier=0 debug=1
to
   options  serial_ir  irq=4 io=0x3f8 type=0 txsense=0 softcarrier=0 debug=1
and it should work, isn't it?
(Oh, whell, the kernel stuff has no option 'debug'..)

Serial_ir loads without useful messages.
Lirc_dev does not get loaded with it. Loading it manually or not doesn't
make any difference.
Irsend will not work. 'hardware does not support sending'


There's another bug of which I don't know wether it is a kernel issue or a
lirc issue.
On kernel 4.9 (and below) lirc compiles modules lirc_serial and lirc_dev
which work equally well as the in-kernel modules lirc-serial and lirc_dev.
You may even exchange them independently. The only difference is that the
lirc version knows about the parameter 'debug'.

When I let /usr/src/linux point to 4.10-rc1, then the exact same source of
lirc does not compile the transmitter part and things don't work!
So using the lirc modules is not even an alternative anymore.
Did I miss something?

(For lirc-0.9.0 you'll need a missing patch for the vanished f_dentry stuff
 in the kernel source.)

Regards, Wim.

A quickly following release of 4.10-rc2 made sure that lirc_dev was loaded
together with serial_ir. However, things still don't work.

I just need to send some codes.
I'm using lirc-0.9.0, which worked fine up to kernel-4.9.1 .

With kernel-4.10-rc1/2 there are two bugs.

1) With the same setup - only the kernel has changed from 4.9 to 4.10 -
   irsend does not work anymore. I get these logs:

Jan  7 01:55:23 localhost kernel: serial_ir: unknown parameter 'debug' ignored

   Where under kernel 4.9 things go well like:

Jan  7 02:25:08 localhost kernel: lirc_dev: IR Remote Control driver registered, major 250
Jan  7 02:25:08 localhost kernel: lirc_serial: module is from the staging directory, the quality is unknown, you have been warned.

Jan  7 02:25:09 localhost kernel: lirc_serial lirc_serial.0: lirc_dev: driver lirc_serial registered at minor = 0
Jan  7 02:25:19 localhost lircd-0.9.0[1970]: lircd(default) ready, using /dev/lircd1
Jan  7 02:25:33 localhost lircd-0.9.0[1970]: accepted new client on /dev/lircd1
Jan  7 02:25:33 localhost lircd-0.9.0[1970]: removed client
Jan  7 02:25:33 localhost lircd-0.9.0[1970]: accepted new client on /dev/lircd1
Jan  7 02:25:34 localhost lircd-0.9.0[1970]: removed client
Jan  7 02:25:34 localhost lircd-0.9.0[1970]: accepted new client on /dev/lircd1

Jan  7 02:25:34 localhost lircd-0.9.0[1970]: accepted new client on /dev/lircd1
Jan  7 02:25:34 localhost lircd-0.9.0[1970]: removed client


2) lirc-0.9.0 gives me the charming choice of using the lirc-made modules
   (lirc_serial, lirc_dev) or the kernel-made modules (lirc_serial,lirc_dev).
   Now kernel-4.10 ruined things, I should at least have the option of using
   the lirc-made modules instead of serial_ir and lirc_dev.
   However, the modules that lirc makes when using kernel-4.10 do not offer
   the possibily of transmission. (It has no variable txsense anywhere in it.)
   Although compiling says '--with-transmitter', there is something in the
   kernel source that prevents lirc from building that in. That is not
   derived from the .config file it finds in the source. I don't know what
   else it is looking for and doesn't find anymore.

Again no answer and another kernel release, but no fixes.


I just need to only send some codes.
I'm using (gentoo) lirc-0.9.0-rc6, which works fine up to kernel-4.9.2 .

In kernel-4.10-rc1/2/3 there are two bugs.

 1) With the same setup - only the kernel has changed from 4.9 to 4.10 -
    irsend does not work anymore. I get these logs:

 2) lirc-0.9.0 compiled with '--with-transmitter' delivers no transmitter in lirc_serial.ko
