Migration from 4.4 -> 6.4 works fine, but ...

[TomWoB]

Hi Tim,

after 1 year nonstop running of moOde 4.4 with my Pi 2B v1.2 and DigiOne soundcard I switched today to actual version 6.4:

• no issues, very smooth migration with latest image (music on external SSD)
  
• done without need of keyboard or display plugged-in
  
• really nice ... donation done a few minutes ago 
  

But one small thing is wrong in my opinion:

The "S Y S T E M    P A R A M E T E R S" show my Pi as follows:

moOde release = 6.4.0 2019-11-24
Raspbian OS    = 10.2
Linux kernel     = 4.19.83-v7+ #1277
Platform          = Pi-2B 1GB v1.2
Architecture  = armv7l (32-bit)
SoC identifier   = bcm2837

If I crosscheck this on Wikipedia, I can found different information for a Pi-2B 1GB v1.2:
Architecture  = armv8-A (64/32-bit)

Really not a big thing, but mabye other moOde users are confused too ...
Btw: why is the following information not longer populated?

• CPU load
  
• clock frequencies
  
• system voltages
  

Thanks for your continuous work
Tom

Hi Tom,

There is a 64-bit kernel option on System Config.

Try the cmd below for monitoring resource usage.

Code:

moodeutl -m

Perhaps @TomWoBs'  point was that he has an armv8-a CPU but the architecture reported is arm7l.

Tom, system info is returning the architecture of the instruction set supported by the kernel, not the architecture of the CPU.

Yes the CPU for the RPi2B is armv8-a, but that just means it can support the AArch64 (64-bit) instruction set [1] as well as the AArch32 (32-bit) instruction set supported by armv7l CPUs.

Since in your example you are running the 32-bit kernel, only the 32-bit armv7l instruction set portion of the CPU is available. Hence uname and other functions report armv7l.

ARM architecture is a complicated subject and IMHO the nomenclature is murky  (https://en.wikipedia.org/wiki/ARM_architecture).

[1] Caveat: I'm speaking Raspberry Pis and their CPUs. There are also 32-bit-only armv8-a chips such as the Cortex-32.

Hi TheOldPresbyope,

yes, you got what I meant ... and thanks for the clarification, I got it .

Hi Tim,

nice "live view" of ressource usage !

Thanks & regards
