  • ws2812-pio-rp1 Kernel Driver seems not functional on RPi5

    Thanks for the log!

    The log shows you have hyperhdr running, better stop that to ensure it's not accessing the /dev/leds0 device node.

    Also you seem to have some "99-com.rules" udev rules - what do you set up there?

    We're building the kernel straight from the RPi kernel repo - only with modified config. AFAICT everything should be in place in our kernel so I have no idea what could be causing the issue. As the ws2812 driver doesn't log any errors/warnings it's hard to tell what the issue may be.

    Device major/minor numbers shouldn't matter at all, they are dynamically allocated nowadays.

    Before opening an issue on the RPi kernel repo better triple-check that it's not some configuration/setup issue on your side, eg try with a plain LE installation on a separate SD card with just the dtoverlay added - and nothing more. Also maybe try asking on the RPi forum first, the Interfacing section might be a good place.

  • ws2812-pio-rp1 Kernel Driver seems not functional on RPi5

    Please provide a full log: ssh in, run "pastekodi" and post the URL.

    I don't have any WS2812 LEDs here so can't test with real hardware, but just adding the dtoverlay with default settings shows both the rp1-pio and ws2812-pio-rp1 drivers being successfully loaded:

    ```BTW: We can't build rp1-pio as a module as that would result in the RPi5 DPI DRM driver being built as a module instead of builtin to the kernel - which means DPI displays wouldn't have display output during boot. If building rpi1-pio as builtin indeed is the culprit then that's a bug in the rp1-pio or ws2812-pio-rp1 driver and should be reported as an issue on the RPi kernel repo.

  • [x86-64] CEC broke after updating to LE 12.2.0

    Have you tried resetting the CEC settings to default? If in doubt, stop kodi and delete the CEC settings file (systemctl stop kodi; rm /storage/.kodi/userdata/peripheral_data/cec_CEC_Adapter.xml) and reboot.

    LE 12.2 ships with a newer libcec (latest version 7.1.1 instead of the ancient 4.0.7 in LE12) and some of your old settings may be incompatible or wrong.

  • Can't map LIRC-Buttons

    Not sure if we have some best practice guide where to put user scripts, you can store them anywhere in /storage, keep in mind though that only the .config and .kodi folders will be backed up by the backup/restore function in LE settings.

    We have a "Showcase" forum here, guess that'd be a good place to present your scripts/settings

  • Can't map LIRC-Buttons

    Unfortunately no, kodi uses a hardcoded set of button codes.

    There is/was an attempt to improve kodi input handling and support remotes via keyboard input handling but it wasn't finished and hasn't been updated for quite a while now...

  • Can't map LIRC-Buttons

    You have to use the remote section of the keymap and map kodi remote button codes, not keycodes, to actions.

    See the devinput section of /usr/share/kodi/system/Lircmap.xml to see how input key codes are mapped to button codes

  • Using a remote control with lircd.conf in LibreElec(12)/Kodi?

    Hmm, you seem to have masked the lircd.socket unit - that's not good, it's needed as lircd is a socket activated service and lircd-uinput starts it by connecting to the socket.

    Remove /storage/.config/system.d/lircd.socket and also /storage/.config/system.d/multi-user.target.wants/eventlircd.service and /storage/.config/system.d/multi-user.target.wants/lircd-uinput.service (the latter two are already enabled by the system), then reboot.

  • [RPi] Automatic Resolution and Refresh Rate Adjustments

    Setup a whitelist and enable "Adjust refresh rate" - see eg here https://wiki.libreelec.tv/configuration/4k-hdr (it applies to non-4k setups as well).

    Also enable "allow double refresh rates" and/or "Allow 3:2 pulldown" if needed - this can help kodi picking the correct resolution if it doesn't have an exact match (but has 2 or 3:2 times the refresh rate).

    If kodi can't find any matching resolution/refresh rate it will use the one that you configured for the GUI.

  • Using a remote control with lircd.conf in LibreElec(12)/Kodi?

    This doesn't look right, you also should see lircd-uinput running (and, yes, eventlircd also has to run):

    Code
    # ps | grep lirc
  489 root      0:00 /usr/sbin/eventlircd -f --evmap=/etc/eventlircd.d --socket=/run/lirc/lircd
  932 root      0:00 /usr/sbin/lircd --nodaemon /storage/.config/lircd.conf
  933 root      0:00 /usr/sbin/lircd-uinput --add-release-events
 2115 root      0:00 grep lirc

    As for key naming: you have to stick to the standard linux input keynames (eg KEY_LEFT etc) - see eg /usr/lib/udev/rc_keymaps/rc6_mce.toml

  • Using a remote control with lircd.conf in LibreElec(12)/Kodi?

    To enable lirc simply copy your lircd.conf file to /storage/.config/lircd.conf and create an empty rc_maps.cfg with touch /storage/.config/rc_maps.cfg then reboot.

    Another option you can try is to use lircd2toml.py (it's included in LE) to convert your lircd.conf file to an ir-keytable toml file - this supports some additional protocols via bpf decoder and may or may not work with your remote. If it works, better use that instead of lircd.

  • HyperHDR suspend not working

    BTW: I did a quick test with LE on a PC and verified that the PrepareForSleep dbus events (which hyperhdr is supposed to listen on) are properly sent on suspend/resume:

    I also checked our hyperhdr build and verified power management is properly enabled.

    So I highly suspect this is some bug in hyperhdr code, you might want to bring that to the attention of the hyperhdr author's - it should work on LE just like on any other linux distro.

  • HyperHDR suspend not working

    What exactly did you do with the suspend script and what do you mean by "it didn't work"?

    After adding the systemd service file to /storage/.config/system.d you have to adjust it (if you changed the webui port number in hyperhdr) and then use "systemctl enable NAME_OF_THE_SERVICE_FILE" to enable it.

    There are two reasons why I didn't include the suspend script in the addon:

    First of all the addon system doesn't support multiple systemd units/services per addon so only the main one (service.hyperhdr) would ever get enabled automatically.

    Second, the suspend systemd file contains hard-coded port numbers of 8090 which won't work anymore (and could upset any other service running on that port) if you change the port number in the hyperhdr configuration. That's quite a PITA, even if you change it it would get overwritten on every addon upgrade.

    Therefore, just use the manual approach, you only have to do it once after installing and it'll survive addon updates as well.

    PS: I can't help testing / verifying if the suspend systemd service works as I don't have any LE systems that support suspend/resume here.

  • Slice4s

    Thanks a lot for reporting back, and glad to hear it's working for you, too!

    You can safely ignore (and actually should dtop) the ancient Linux patches, they are no longer needed nowadays.

    The mmc patch dates back long before we switched to reference the flash and system partitions by UUID, when the EMMC/SD card device ordering still mattered - with UUIDs it doesn't matter if the EMMC is /dev/mmc0 or /dev/mmc1.

    The cs4265 patch also predates changes to the upstream cs4265 driver and isn't needed anymore.

    And the alsa card conf was only needed for kodi so it recognises an IEC958/SPDIF capable device to allow AC3/DTS passthrough via Toslink(SPDIF. A few years ago I looked into improving the (incomplete) SPDIF support but realized a lot of important bits were missing in the cs4265 driver to transmit proper channel status information - then gave up and shortly afterwards SPDIF got broken again in the cs4265 driver due to changes in the upstream code. So better use HDMI if you need/want to pass through AC3/DTS/..., receivers with only SPDIF input are also quite rare today.

  • Slice4s

    Please give this slice-drivers branch a try: https://github.com/HiassofT/slice…/kernel-5.10%2B

    And here's an LE13 branch that pulls in the driver for RPi2 (you'll need to adjust the RPi4 options for your CM4s): https://github.com/HiassofT/LibreELEC.tv/tree/le13-slice

    A few years ago I tried to clean up the slice (soundcard) driver, I dug out the branch again and noticed a couple more fixes are required now and added those today (I also ran into the distorted sound issue).

    The RPi2 LE13 build worked fine on my Slice with CM3 with just dtoverlay=slice added to config.txt (this enables audio, IR and the RTC), analog audio out sounds fine now.

    Note: SPDIF out doesn't work since a change to the cs4265 upstream driver some years ago, I haven't looked at that.

    I also didn't care about the dt-blob.bin files from the slice-firmware repo, using the blobs from old Slice images works fine to get USB/ethernet working - you may need to create your own dt-blob for CM4s.
