Hi umtauscher - LE11 nightlife’s are now all built with 5.15.5

Stepping back a bit: the udevil service on LE mounts the hard drives under /var/media

Any disk that does not meet the following conditions is automatically mounted - https://github.com/LibreELEC/Libr…vil-mount.rules if you do not want something automounted by udevil - then it must be excluded by one of these criteria.

Going to your question - using the docker argument: -v /var/media/data:/data would be like typing the following command in the Docker container: # mount /dev/sda1 /data

So it’s not really an nvme / sata question. More as saying - I am mounting a directory from my host operating system as a mount point in my container.

# journalctl -f

Hi Grasshopper - https://github.com/LibreELEC/LibreELEC.tv/pull/5878 is still in the Queue for LE10, which is why you are not seeing it updated yet.

A bit of googling and it seemed these are the details of the chip (potentially). Next is getting a dts/dtsi… test …

• WiFi/Bluetooth - unnamed dual-band IEEE 802.11 a/b/g/n Wi-Fi/Bluetooth 4.0 marked HK5230;
• This is a 2011 IEEE 802.11 a/b/g/n Wi-Fi/Bluetooth 4.0 module - Ampak AP6330 on the BCM4330 chip.

If you install network-tools on LE. I’m going to guess it in upnp / mdns

tcpdump host nasip # (if it is not broadcast traffic)

# for broadcast traffic - I’ll leave that an an exercise for the reader. You could also create a pcap file and review via wireshark. But pretty sure that simple “tcpdump host nasip“ should get you heading in the right direction

Yes. Is the quick answer. Something similar is how I do things at the bottom.

Things to consider: overlays, symbolic links (ln) docker configuration, if it breaks it all goes bad. I have grabbed a section my autostart.sh. Please don’t use it as-is. As I use my nvme0n1p6 drive as DATA but also store my docker setups.

For running a docker container - I use

docker run --workdir /var/media/DATA/home-rudi/LibreELEC.tv --privileged -v /storage:/storage -v /var/media/DATA:/var/media/DATA -it le-focal:latest bash

There is no reason if you wanted /var/media/DATA as DATA - use

-v /var/media/DATA:/DATA

My autostart changes - don’t use as-is

more .config/autostart.sh 
(
        # mount the overlays
        mkdir -p /storage/.kodi/userdata/addon_data/service.system.docker/docker/overlay2
        mkdir -p /var/media/DATA
        mount -o rw,suid,dev,exec,atime /dev/nvme0n1p6 /var/media/DATA
        mount -o rw,suid,dev,exec,atime /var/media/DATA/.docker/overlay2 /storage/.kodi/userdata/addon_data/service.system.docker/docker/overlay2



        mkdir /var/media/ramdisk
        mount -t tmpfs -o size=32g tmpfs /var/media/ramdisk
        # docker pull oznu/homebridge:ubuntu
        # docker container prune
        # docker run --net=host --name=homebridge -v /storage/homebridge:/homebridge oznu/homebridge:ubuntu
        docker restart homebridge
) &

At a quick scan I can’t see hci, Bluetooth, or bt in the kernel dmesg. Is the DTB file enabled to support a Bluetooth device?

Thank you for testing. The update librespot version has been added to both LE10 and the LE11 branch. It should be available over the next few days.

Anybody to test this update?

Hi itisljar - mc has been compiled without wchar support (wide character) thus why it is only displaying the standard ascii table. Of recent times when wchar was introduced, I patched it out. It has been subsequently patched in the upstream version to allow compile with/without wchar support. Technically it can be enabled - but would require some work on the Unicode support.

Based on https://github.com/torvalds/linux/search?q=RPCSVC_MAXPAYLOAD the kernel is set to 1MB for TCP

So what are the tcp window sizes? And the latency?

nuc11:~ # cat /proc/sys/net/ipv4/tcp_wmem

Quote from JurKub

the Ethernet interface is not the issue

using Samba everything works fine

Hi JurKub - agree - I don't think it is the ethernet card / cabling / ... itself either. Just trying to isolate the Kernel Settings / Drivers / ....
Given the number of changes all happening - think that "a regression" may be a possibility. I just don't know where to look as such. E.G is it sending / receiving / window size / UDP / TCP / ....
what does

``time cp /nfs/abc /ramdisk/

take ... etc

Hi grinser - zip file here. Let me know how you get on. https://github.com/heitbaum/Libre…-10.0.0.129.zip

Does iftop / nmon show anything useful?

PRs raised for the update to 0.3.1 of librespot

But I would request some testers. Thanks

If you need a zip image. Please let me know what LE version and what hardware.

Hi caddar - there are updated versions of librespot. I would be happy to look at updating the the LE10 addon, but would need a couple of testers. Let me know - and I’ll look at finishing the packaging for the 0.3.1 version. https://github.com/librespot-org/librespot/releases

Please let me know what hardware and version of LE you are running - so that I can build a test addon for you.

Hi isamudaison - the TGL (nuc11) works with 10.0.1, from a boot perspective. There are some glitches with the graphics until kernel 5.12 - please use nightly and let me know how you go. Also I would like to see your logs at some stage to check why / what is the error occurring with the PN41
