I finally have openZFS loading as a module with modprobe (still need to test that it's actually working correctly, but so far so good...)
I'm using the Armbian Lunar CI rolling release since there is a working Linux-Header for this kernel
https://imola.armbian.com/beta/pool/main/l/linux-headers-midstream-rockchip-rk3588/  
After that, I essentially followed the instructions for building openZFS, but some minor changes to the META file for license and max kernel version.
 
I want to say thank you to all the Armbian team members for making such an amazing platform for SBCs. All my boards run Armbian.
 
here was the config command I used
git clone https://github.com/openzfs/zfs cd ./zfs sh autogen.sh ./configure --with-config=user make -s -j$(nproc) sudo make install sudo ldconfig sudo depmod sudo modprobe zfs

With working PCI
https://github.com/armbian/os/releases (look for Rock5 "midstream")
 

@slymanjojo
If you don't need the transcoding - the minidlna package could be a good alternative, low resource usage and the performance mostly will depend on your network and the reproduction device.
Once HW transcoding makes it to the latest kernels, the other packages should behave much better - you're not the only one waiting for it.

Thanks.
 
Now we may consider switching all boards to MGLRU on 6.1 😀

Thanks a lot, ended up that yesterday I tested kernel v5.18.0 on rk322x with the old version of the extra patch compiling the whole debian mesa packages ecosystem with success. The box was sporting just 1gb of ram, 512mb of zram swap space and 2gb of extra USB HDD swap file.
The conditions were absolutely heavy and unhealthy, but the whole packages rebuilding from sources finally completed without errors, even after extreme swapping and hours of compilation time. The system was always responsive to SSH shells, which is a great achievement by itself!
 
 

@hartraft - there are two kernel options for mglru: CONFIG_LRU_GEN=y and CONFIG_LRU_GEN_ENABLED=y - the first is to have mglru built into the kernel and the second is to have it enabled by default - if they are not in your kernel config it might be required to rebuild the kernel with them (or at least the first) enabled

@hartraft Currently, I can assure you that the tinkerboard with armbian edge kernel (6.1) receives MGLRU compiled and enabled by default because I maintain the rk3288 (rockchip 32 bit) family.
The other two boards are not under my maintenance so I can't say anything about, but you could check in the config sample file in your /boot directory to see if a kernel is compiled with the options pointed by @hexdump

Finally! On my personal testing on 5.19.x never had any issue with both armhf and arm64 architectures

@ebin-dev @piter75
I believe the upstream fix https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/drivers/regulator/core.c?id=8a866d527ac0441c0eb14a991fa11358b476b11d will do the job (in 6.1-rc1 so to be expected in Armbian edge if you want to try EMMC anew when it lands). This is likely the same issue as before the bad commit I pointed at the code only called set_machine_constraints once.  Still, requires testing (I saw that a lot of rk339 boards removed hs400 in Armbian, maybe that will fix them all).
 
regulator: core: Resolve supply name earlier to prevent double-init Previously, an unresolved regulator supply reference upon calling regulator_register on an always-on or boot-on regulator caused set_machine_constraints to be called twice. This in turn may initialize the regulator twice, leading to voltage glitches that are timing-dependent. A simple, unrelated configuration change may be enough to hide this problem, only to be surfaced by chance. One such example is the SD-Card voltage regulator in a NanoPI R4S that would not initialize reliably unless the registration flow was just complex enough to allow the regulator to properly reset between calls. Fix this by re-arranging regulator_register, trying resolve the regulator's supply early enough that set_machine_constraints does not need to be called twice.

Note that this fix reintroduce the less critical bug that was fixed by the bad commit I pinpointed namely sysfs entries issues; This was also fixed in 6.1-rc1 by commit https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/drivers/regulator/core.c?id=520fb178212d1dd545ed0ed231df09111b30ab7e "regulator: core: Fix regulator supply registration with sysfs"

I do love the XU4, but it only sports 2GB of RAM.

I am working with: Linux helios64 5.10.63-rockchip64 #21.08.2 SMP PREEMPT Wed Sep 8 10:57:23 UTC 2021 aarch64 GNU/Linux
I have snapraid configered via the OMV interface but MergerFS and LUKs manually because the plugins were not present at the time but I am not sure if this really does any difference. Beyond that I am using some Dockers like Airsonic, Jellyfin, Nextcloud.
And the ondemand governor is now between 400-1800MHz and runs all the tasks (Snapraid + rsync + smart on a weekly basis) smoothly. My current uptime now is 21 days.

Mind if I ask which kernel are you using? and did you experience any problems adding any addon's? I had no problems with a fresh install of Bullseye on my Helios4 but had issues when I tried adding snapraid and mergerfs on my Helios64 with the stock Bullseye Kernel.
 
Also Experiencing a freeze/issue When installing OMV through armbian-config where it freezes at the end while processing triggers for man-db

Since 4 weeks now I am runnign the helios64 together with OpenMediavault 6 with the full CPU capacity and ondemand governor.
Before I had always problems when doing an scheduled task but with OMV6 the problem seems to be solved. I am quite pleased now with the performance and a rocksolid NAS.
 

UPDATE:
Even changing the cables, the disks keep failing over time. I wasn't able to have my NAS running more than a day or two without a failure on the disks. After buying an APC UPS with Boost and Trim Automatic Voltage Regulation (AVR), my NAS is now running without any failure over more than a week!
So the problem was the unstable energy in my house. Maybe I'll try to put back the original ones to see if it works.

Go ahead, OMV6 works fairly well with the Helios64... there are some bits and pieces that are not completely ported (plugins for example) and some need a bit of adjustment whatsoever. But all in all it is okay.
 
I am running OMV6 together with SnapRaid. MergerFS and Luks I am running outside of OMV as I do find it easier to customize for my needs.

I have been trying for a while now the edge kernels and I have found that after the HW-mod (above) the network bonding has started to work... not consistently but once setup, the next reboot will actually enable the full network bonding. Currently I'm running 5.15.4, had to rebuild ZFS but that was it.

Hi,
 
I thought this forum did support on the Helios{4,64} regardless of the OS since Kobol is now closed.
More, the issues I encounter testing the Armbian patches can be helpful for the future Armbian releases (I had the eMMC issues long time before many Armbian users were impacted with the Buster update).
I did tried to apply the Armbian patches for kernel 5.15, but they fail because Helios4 and 64 are now mainlined.
 
But not problem, I will try to fix it by myself, and report back the solution here. I have the skills to do it.
BTW I have the same issue with vanilla kernel 5.15 and Helios4. I will test it first on the helios4 because it's not used anymore.
 
Kind regards,
Xavier Miller

Hi jotapesse, yes same for me ... but on closer inspection ... the flashing of the LAN activity light no longer seems
to be tied to real network activity!
 
1/ It flashes a lot less than it used to do.
2/ If I download a large movie file from the Helios64 to my PC I occasionally see a brief flash, but not the sustained activity that
I'd expect from a download that takes several minutes.
3/ Inspecting my network router, I can see constant low level activity on the Helios64 ip address (I only have one ethernet cable attached to the Helios64)
but don't see any flashing LED.
 
So in conclusion ... its still not working properly!  

Hi everyone! Just to let you all know that I have updated today my Helios64 to Armbian 21.08.3 Bullseye and the "LAN" front panel led now works again. :-) Great!

New version 20211007-edge with 5.14.9 core. All equipment works, including analog sound and remote control.
 
@JMCC
I checked the operation of your KODI-18 packages on this kernel, KODI starts, but there is still an error and the video does not play, maybe I forgot some kernel options or a patch. I plan to check it again in the near future.

I have slightly different approach to going's solution, but this would be compatible with it
 
 

@piter75 commited the emmc fix into Armbian and built Armbian 21.08.2 which is already available through the Armbian mirrors (via 'apt update && apt upgrade').
 
It is save to upgrade your Buster or Bullseye installation to Armbian 21.08.2 - but emmc read speed will be about 50% what it used to be.
 
You can roll back to the previous linux 5.10.43 kernel if you don't like that - just install those files with 'dpkg -i *.deb'.
 

Really ?
If you are on macOS Big Sur all the drivers and apps are already there. If you need to access the serial console of your Helios64, just connect your mac to the USB-C port of your Helios64. A device such as  /dev/tty.usbserial-XXXXXXXX will be recognised by macOS. All you need to do then is to enter the following into the Terminal of your mac (X to be replaced):
 
screen /dev/tty.usbserial-XXXXXXXX 1500000 -L  
Edit: If the 'screen' command on macOS does not show the output of the bootloader (scrambled characters) you could use the app serial. The only thing you need to configure is to set the serial speed manually to 1500000 bps.
 
If someone would like to contribute in kernel testing - the Armbian build system is very easy to install and use. All you need is an Ubuntu 21.04 (amd64) installation. All the rest is explained here. To compile your own kernel is then as simple as this:
./compile.sh BOARD=helios64 BRANCH=current KERNEL_ONLY=yes RELEASE=bullseye  

Armbian "current" (5.10.y) compiles without issues.
I second @Igor's opinion that a change somewhere in this diff broke the eMMC.
I tried reverting a few obvious parts of it, like the mmc driver changes, but without success.
 
However I did find that with the unit I have the issue happens only in hs400{,es} modes.
With those disabled my unit works fine and I can use nand-sata-install to transfer os from SD to eMMC successfully which is not possible with 5.10.60+ and hs400 enabled on eMMC.
 
If anyone wants to check if switching eMMC to hs200 mode works also on their unit, here is how:
Upgrade the kernel to 5.10.60, but don't reboot yet.
Run:
curl -o rk3399-kobol-helios64.dtb https://users.armbian.com/piter75/helios64/rk3399-kobol-helios64.dtb sudo cp rk3399-kobol-helios64.dtb /boot/dtb/rockchip/rk3399-kobol-helios64.dtb sudo reboot  
If this workaround works I will disable hs400{,es} (again) in Armbian until the underlying issue is found.
There will be a performance penalty to that change but keep in mind that Helios64 was originally released with hs200 and only recently gained hs400 back ;-)
Below you can find the comparison between hs400 and hs200 modes using iozone.
