lirc_rpi module, possible bug in kernel > 3.6 #525
Comments

I have checked the lirc timing problem on a number of versions of software. |
|
This driver was provided as a pull request, so I don't know much about it. Can you confirm if the issue only affect transmission, or is there a problem with reception? @ar0n @cleverca22 You were involved in the original driver - any suggestions? |
|
Receiving works, but irrecord spit out a slightly different lircd.conf: Linux host1 3.6.11+ #557 PREEMPT Wed Oct 2 18:49:09 BST 2013 armv6l GNU/Linux Linux host2 3.10.28+ #634 PREEMPT Sun Feb 2 15:16:25 GMT 2014 armv6l GNU/Linux |

I performed the following experiment which confirms it is only a fault with the transmission. irrecord puts the correct parameters in the lircd.conf file for both 3.6.11 and 3.10.29. The timing produced in transmission is wrong in the 3.10.29 version. (which is the same as posted above, but I wanted to confirm the actual numbers and measurements.) Starting with software version 3.6.11+ #557 PREEMPT Wed Oct 2 18:49:09 BST 2013 Using mode2 -d /dev/lirc0, recorded the pulses from the foxsat remote power button (key_power). The header pulse was displayed as 8982 Using irrecord -d /dev/lirc0 ~/lircd.conf, recorded button presses from the humax remote Found const length: 107290 The lircd.conf included the following line: Changed the name in ~/lircd.conf to foxsat-hdr and copied the file to /etc/lirc Started up lirc again with sudo /etc/init.d/lirc start Performed a sudo rpi-update to: Checked the header pulse Repeated the above experiment of learning the remote, making a new lircd.conf file and measuring the new header pulse. Using mode2 -d /dev/lirc0, recorded the pulses from the foxsat remote power button (key_power). The header pulse was displayed as 8980, (before was 8982, so effectivily the same) Using irrecord -d /dev/lirc0 ~/lircd.conf, recorded button presses from the humax remote. Found const length: 107290 The lircd.conf included the following line: (this was effectively the same as before) Ran the command irsend send_once foxsat-hdr key_power |

I don't have the equipment to check this out now, but can somebody test it with this version: ar0n@69af0bf |
|
I tried this a couple of weeks back and got a file not found error message. sudo rpi-update 69af0bf 100%[======================================>] 7,174 --.-K/s in 0.02s 2014-02-17 07:45:20 (397 KB/s) - `/usr/bin/rpi-update.tmp' saved [7174/7174] *** Relaunching after update |
|
finally set up a cross-compile toolchain to test the code aron mentioned. will post an update with my findings tonight. |
|
@ar0n : doesn't work with ar0n@69af0bf |
|
I have the same kind of behavior with Raspbmc which is using a 3.10.24 kernel. |
|
I don't use Raspbmc and have not configured the Pi to be overclocked. Looking at my /boot/config.txt confirms the Pi is running at the default 700MHz. So, I think this not the cause of the problem. |
|
Ok, that's not the overclocking factor... I made some tests replacing udelay (and rounding to nearest us) by ndelay in the code, and it seems to work pretty well Here are the patched lines : |
|
@jjmz interesting. First can you just call ndelay(d * 1000) rather than udelay(d) just to rule out an issue with udelay not being accurate. |
|
@jjmz : |
|
replugged/rewired what was possible: now it's working with jjmz's patch. =) |
|
If someone could tell me how to do the "cross-compile toolchain" mentioned earlier by koromar, I will try to incorporate this patch and measure the timings on my system. |
|
I also want to test,, but how to cross compile.. |
|
I've uploaded the kernel incl. modules. This way you can test without having to crosscompile:
If the boot of the new kernel fails, power down the raspi, put the sd card in another machine and change the config.txt "kernel=kernel_new.img" to kernel=kernel.img. This should then boot your last kernel next time you start the rpi. As for cross-compiling howtos, I've used those two: one is missing the modules-part, the other has a better description of all the necessary steps. |
|
Same problem with 3.10.33+ updated this morning |
|
Hi koromar. I tried using your kernel modules , my system was at 3.10.33+ #656. The system boots into 3.10.30+ #1 but I get 3 error lines ending with "......could not open moddep file '/lib/modules/3.10.30+/modules.dep.bin" and a "FAIL: unable to load LIRC kernal modules". |
|
@jjmz (and other testers) First, just change the latency: Second, just change the rounding Third use ndelay rather than udelay Fourth just change the scaling |
|
Where can I get the source code for this? |
|
@GeofP : jjmz's second post has the patchlines. |
|
I've run into some strange errors compiling the latest version from github with a config from an up to date raspberry 3.10.33+ . The kernel won't boot and the lirc_rpi.ko kernel module has (at least) a different size (not sure if this is a part of the problem yet). |
|
To get that right config do: Maybe try a make clean before building. |
|
I was unable to build a module matching the latest one installed with rpi-update. So I did rpi-update on the pi and a git pull on the vm with the cross-compile env. again - still didn't work. I then built a new kernel (with .config from bcmrpi_defconfig) and 5 different lirc_rpi.ko for that: My results: Download Link: https://www.dropbox.com/s/tvv2cn32761rlka/custom-3.10.33.tar.gz The archive contains: I also wrote a little howto and tried to be as exact as possible, but I guess it couldn't hurt to do an additional backup in your own accustomed way. Download Files: Unpack Files: You should end up with something like this: get a root shell: Backup current modules+firmware Copy custom kernel + modules, firmware Now edit /boot/config.txt, change "kernel= " to: You can reboot now to test if this worked for you. When you did do that, a "uname -a" should show: along with some other info. To restore : Choose Kernel Module: get a root shell (if you're not root anymore) switch working directory: stop lirc unload kernel modules: select kernel module by copying: start lirc (will automatically load kernel modules) do your tests. repeat steps "stop lirc" to "start lirc" for other modules. note:
Hope this will work. |

@koromar It looks like LIRC_TRANSMITTER_LATENCY is a 24.8 fixed point number of microseconds. i.e. It seems both these numbers are made up. Anyone know what value this should really have? I guess by testing the frequency error (e.g. with a scope) of the "vanilla" and "latency" kernels, we can determine if 20 is correct, too high or too low, and predict what value would give the perfect frequency. |
|
LIRC_TRANSMITTER_LATENCY has been copied from the original lirc serial module, where its defined as LIRC_SERIAL_TRANSMITTER_LATENCY. This is used to correct uart latency, on platforms without time stamp counter (RDTSC instruction). On platforms where the RDTSC instruction is available, the pulse widths are calculated in a more accurate way. I don't know if we can rely on the timex.h get_cycles() ( linux/arch/arm/include/asm/timex.h Line 22 in a987a78 |
|
The rpi kernel has a 1us resolution timer available (see frc_clock_ticks32 in bcm2708.c) which is most likely what get_cycles() reads, so it should be possible to use that. |
|
@popcornmix |
|
@ar0n I have carried out the trial as described by @koromar and taken some frequency measurements for the different kmod versions. lirc_rpi.ko-latency produces less error than all the others, although lirc_rpi.ko-scaling is also an improvement. The measurement are taken with an oscilloscope on GPIO pin 17. See results in the following table. |

lirc_rpi: Use read_current_timer to determine transmitter delay. Thanks to jjmz and others See: #525 lirc: Remove restriction on gpio pins that can be used with lirc Compute Module, for example could use different pins lirc_rpi: Add parameter to specify input pin pull Depending on the connected IR circuitry it might be desirable to change the gpios internal pull from it pull-down default behaviour. Add a module parameter to allow the user to set it explicitly. Signed-off-by: Julian Scheel <[email protected]> lirc-rpi: Use the higher-level irq control functions This module used to access the irq_chip methods of the gpio controller directly, rather than going through the standard enable_irq/irq_set_irq_type functions. This caused problems on pinctrl-bcm2835 which only implements the irq_enable/disable methods and not irq_unmask/mask. lirc-rpi: Correct the interrupt usage 1) Correct the use of enable_irq (i.e. don't call it so often) 2) Correct the shutdown sequence. 3) Avoid a bcm2708_gpio driver quirk by setting the irq flags earlier lirc-rpi: use getnstimeofday instead of read_current_timer read_current_timer isn't guaranteed to return values in microseconds, and indeed it doesn't on a Pi2. Issue: linux#827 lirc-rpi: Add device tree support, and a suitable overlay The overlay supports DT parameters that match the old module parameters, except that gpio_in_pull should be set using the strings "up", "down" or "off". lirc-rpi: Also support pinctrl-bcm2835 in non-DT mode fix auto-sense in lirc_rpi driver On a Raspberry Pi 2, the lirc_rpi driver might receive spurious interrupts and change it's low-active / high-active setting. When this happens, the IR remote control stops working. This patch disables this auto-detection if the 'sense' parameter was set in the device tree, making the driver robust to such spurious interrupts.

lirc_rpi: Use read_current_timer to determine transmitter delay. Thanks to jjmz and others See: raspberrypi/linux#525 lirc: Remove restriction on gpio pins that can be used with lirc Compute Module, for example could use different pins lirc_rpi: Add parameter to specify input pin pull Depending on the connected IR circuitry it might be desirable to change the gpios internal pull from it pull-down default behaviour.

My /etc/lirc/lircd.conf includes the following parameters:
........ pulse space
header 9590 4730
one 630 1755
zero 630 560
frequency was not defined but the default is 38KHz
The software version of the re-installed software is as follows:
Linux Geof-Pi-1 3.6.11+ #557 PREEMPT Wed Oct 2 18:49:09 BST 2013 armv6l GNU/Linux
Measurements on the storage oscilloscope were as follows:
Header pulse = 9.7ms
frequency = 38KHz
These measurements show the timing for lirc is now correct.
Before the install of the mrgrey software version, my version was:
Linux Geof-Pi-1 3.10.25+ #622 PREEMPT Fri Jan 3 18:41:00 GMT 2014 armv6l GNU/Linux
Measurements on the storage oscilloscope were as follows:
Header pulse = 8.2ms
frequency = 45KHz
These measurements show the timing for lirc is wrong. ..."
