Is your feature request related to a problem? Please describe:

No

Describe the solution you'd like:

Add NPU support for 3B

Describe alternatives you've considered:

Use the official image from OrangePi or the image from Armbian

Also, is that possible? It looks like we are on the mainline instead of the Rockchip one.

Use the official image from OrangePi or the image from Armbian

We do own kernel builds with a soft-fork of the Armbian build system. In case of Orange Pi 3B, it is the edge branch, hence mainline kernel, not Orange Pi vendor kernel.

I guess the NPU requires particular drivers, which are not implemented into mainline Linux (yet)? We could provide vendor kernel builds, but I would prefer to see a way to have the needed drivers in mainline Linux. Maybe you have some more information/background, as you actually aim to make use of the NPU?

Yes, I am currently working on getting Immich's ML running on the RKNPU. (I am still figuring out how to resolve issues with get_inputs and get_outputs btw).

For testing, I need to swap to another SD card with Armbian installed. It's a bit inconvenient, it’s manageable for now.

[MichaIng]

Ah, with Armbian it works? With the Linux v6.1 image, not the v6.6 image, right?

It boots!

[MichaIng]

Sure it boots 😄. Or you mean the NPU works with it?

[yoni13]

Yep 😅 MichaIng ***@***.***> 於 2024年12月6日 週五 下午9:45 寫道：

Okay great. I'll add the vendor kernel to the APT repo component for the Orange Pi 3B, so it can then be easier installed and kept updated.

[yoni13]

I just noticed a issue with ulimit while trying to create a mc server

root@orangepi3b:~# ulimit -u
488

Might be this:Joshua-Riek/ubuntu-rockchip#919

[MichaIng]

Before we add patches, can you test the latest build of this kernel?

cd /tmp
wget https://dietpi.com/downloads/binaries/testing/linux-{image,dtb}-vendor-rk35xx.deb
dpkg -i linux-{image,dtb}-vendor-rk35xx.deb
reboot

The NPU works, what would you also want to test?

[yoni13]

The RKMPP also works btw.

[MichaIng]

Is the ulimit correct with that one?

No

ulimit -u

[MichaIng]

Okay, I'll create a build with these two patches:

• Joshua-Riek/linux-rockchip@9b0de6b
• Joshua-Riek/linux-rockchip@c91ccee
