Power usage with latest Kernel 6.12 Server Ubuntu build

[Thewonderer]

Hi,

 

I've come from Joshua's 24.04 Server build.  I was concerned that the support was dropping off as he's having a well deserved break.

 

I've installed the latest Server build from here.   https://dl.armbian.com/orangepi5-plus/Noble_current_server-kisak

 

Works fine, have moved it to EMMC and removed the SD card.

 

I use a USB power meter to see how much juice it uses.

 

I noticed this build uses about 20 to 25% more when idle or under load compared to Josh's 6.1 kernel build.  I am suspecting 6.12 has enabled more hardware in the OPi5+ and this is the reason.

 

Is there a way to disable some of the HW to lower the idle power usage?

 

On average it uses 5w on idle.

 

Thanks.

 

Loving the Armbian build.

Some time ago I also that various powermeasurements on my NanoPi-R6C and lowest was 1.5Watt. Was with NVME removed and kernel 6.1.75-vendor, 1Gbit GMAC ethernet. With CLI-tool 'btop' it is easy to see that idle lowest clock is 408Mhz.

With kernel 6.10.10-manline, the lowest clock is 1000Mhz, AFAIR idle was then 2.3Watt. Also checked with NVME inserted again, that adds another 0.3 Watt (when NVME is idle, uses way more when stressed a lot). This NanoPi-R6C is RK3588S SoC, OP5P+ is RK3588 and has more peripherals I think.

Used OS was Debian Bookworm based.

 

Just a quick check now with 6.12.5-mainline: 2.24Watt idle, clock 1000MHz. This is with Samsung 970 EVO+ NVME connected and OS running from it.

I think support was dropped because:

- asking from him/us 1000 x more then he/we could deliver,

- users complete absence of reality (tl; dr;),

- users egoistic perspective as primary objective, 

- usage off private communication channels

- constant fight to get attention they don't deserve to get, 24/7 (from on person that needs to have its own life),

- asking amateurs to do in super limited time what pros in months or years can't,

- constantly attacking with "small" questions that requires hours or weeks of research in order to answer, months to fix some problem (users expect 1day resolution)

- most of damaging-time-wasting clients are powered by Dunning-Kruger, so the loss of our super precious time is ridiculously high,

- complete absence of financial support from amateurs,

- complete absence of financial support from professional abusers of open source (some HW vendors and their clients are not),

- constant pressure, stress and no emotional rewards whatsoever,

Even users treated him like shit and act abusive, same as here sometimes, he tried to be polite and professional. I don't known anyone that could endure constant insults very long while paying (!) for the time taking them. Imagine being a party host - how long you will stay professional when people f* with your family and puke around your condo? And how long you will host such parties? This is how this relationship looks like, if we allow your frustration to be in charge.

 

I understand that bugs in software are terrible thing, I also feel bad when this happens to me ... but can't pin bugs to us or requests features if you have no idea what you are asking for. We are minimizing this problem for everyone, to find sane grounds.

Welcome!

Joshua Ubuntu and Armbian Ubuntu are HW wise identical. He was contributing to the kernel our team maintains and we also supported him financially within our possibilities. Those two distros are different in user space / cosmetic details. We don't try to be Ubuntu, he tried to be Ubuntu. We removed Ubuntu stuff, snap is not preinstalled, there is ... I see value in Ubuntu packages as they tend to be more recent and polished then Debian Stable. Similar user-space philosophy as Linux Mint in PC world. This might give some insights https://docs.armbian.com/#comparison

Compare his 6.1 to Armbian 6.1 and you won't see any difference. Mainline, 6.12.y kernel is totally different thing, it has been developing more or less from scratch for more then two years. And is not fully completed AFAIK.

Very simple   Use kernel 6.1.y

 

If you find the way with 6.12.y, kindly share this information with others. Perhaps someone knows and will tell this. I don't know.

Thank you Igor and Eselarm.

 

I saw some of the github issues Joshua had to deal with.  Glad he's looking after himself by walking away.

 

I believe Kernel 6.1 is the Android Kernel Rockchip released and was hacked together by them.

 

I know Sebastian and colleagues having been chipping away at Collabora ....

 

https://gitlab.collabora.com/hardware-enablement/rockchip-3588/notes-for-rockchip-3588/-/blob/main/mainline-status.md

 

I like the idea of using btop, but from what I can see it needs to be compiled, so will try that later. 

 

I recall when I had a Rock64 that, when the kernel enabled all the hardware features, the power usage did increase.  As my install is a headless server, I could probably disable the HDMI and a few other things.  

 

It's not a major deal, but it would be nice to reduce the power usage when idle.

 

Keep up the great work!

Actually the first bsp was that which was built around a 5.10.110 and later .160 android hacked together kernel. 6.1 is AFAIK a real linux kernel rockchip used for newer bsp.
