OpenWRT on Raspberry Pi 3B: CPU info not working

[nathhad]

Okay, testing on this one as of commit 8ad5a71

Output:

cpu ~ -ash: ./components/cpu_gpu.sh: =~: not found

This one is at least easy to explain as =~ is a bash-only comparison operator, and is what's causing the issue under ash. I was able to fix this quickly on my local copy by editing line 8 to the following:

elif $vendor && [[ "$vendor" = "GenuineIntel" ]] ; then

That provides the following simplified result (but still works fine on my other Debian11/x86 test machine):

cpu ~ [email protected]

That to me I would consider 100% okay on a board like this that provides so little cpu info, it's basically ideal.

Duplicate of issue #23

Thank you for providing information from all of your devices! Can you test my last commit? It should hide now hopefully.. This could be stubborn

[nathhad]

Pulling most current version and testing now, results to follow!

Not working at present, output is:

cpu ~ ash: GenuineIntel: unknown operand

I think the issue is in the line

elif $vendor ; [[ $vendor =~ "GenuineIntel" ]] ; then

Something doesn't look quite right there to me - but I haven't quite parsed what yet. But ash is parsing that line in such a way that it's thinking "GenuineIntel" is a command, and throwing quotes around it hasn't helped. Will continue to poke it with a stick and see if I can see what's going on with it.

Potential progress, switching that line to:

elif [[ "$vendor" =~ "GenuineIntel" ]] ; then

Resolves the error text within the output, and gets us back to output that looks like this:

cpu ~ [email protected]

Which looks perfectly serviceable! That may be the fix since we don't have an easily identifiable chip name for this one.

That said, I did also import it to a couple of my slightly older models with older ash compiles, and they do have trouble with the =~ operand:

cpu ~ ash: =~: unknown operand

That should hopefully be a little easier to resolve.

Need to get ready to crash for the night, so I may get slow to respond! I'll probably have to pick back up tomorrow morning.

I pushed a commit that I think will fix it. I did not notice that 'GenuineIntel' was not parsed as a string

[wick3dr0se]

Thank you for your testing and solution! I made the changes you requested. I can't verify because I have AMD cpu but it should be good. Closing now as solved!

Testing on commit 579d217 and don't see the change working - I do see line 8 was changed, but the line as changed still causes errors.

Current code: elif $vendor && [[ $($vendor = GenuineIntel) ]] ; then

Error output: components/cpu_gpu.sh: line 8: =: not found

Recommended syntax: elif $vendor && [[ "$vendor" = "GenuineIntel" ]] ; then

Output:
ash/busybox/openwrt: cpu ~ [email protected] (expected and good)
bash/debian11/x86: cpu ~ Intel Core i7 M 640 [email protected] (also still good)

The output on x86 on my machine does include a lot of extra whitespace that for some reason doesn't get reproduced when I copy it in here, but that's a whole separate little quirk that can be prettied up later.
