What are your kernel compile times?

lunainvictum · January 9, 2022, 9:24pm

Interesting. Because if i do it like you said, the secound time is about ~10x faster.

I don’t know what I’m doing wrong. I extract the file and cd into the directory. I do make mproper followed by make deconfig. So far so good but now when I do the time command i get all kind of errors and it finishes even faster.

What errors you get.

You dont running Endeavouros? In EndeavourOS you need base-devel. Dont know what you need on Arcolinux.

jonathon · January 9, 2022, 9:31pm

make clean will remove previously-built files.

If you don’t do that it won’t recompile them, because make won’t do work when it’s not needed.

I’m on my other machine now. I did pacman -S base-devel --needed and everything was already installed.

anon13373109 · January 9, 2022, 9:32pm

Ok so I’ll try again and after the make deconfig I’ll do make clean first?

moson · January 9, 2022, 9:38pm

imho mrproper should also “clean”. Not sure if it really wipes everything.

make clean
time(make -j$(nproc))

should do it

# make clean     Delete most generated files
#                Leave enough to build external modules
# make mrproper  Delete the current configuration, and all generated files
# make distclean Remove editor backup files, patch leftover files and the like

How did you create the ramdisk? maybe there is some issue with it? (or with your RAM itself)

jonathon · January 9, 2022, 9:44pm

anon13373109:

[chomsky@ArcoLinux linux-5.8.3]$ make mrproper
[chomsky@ArcoLinux linux-5.8.3]$ make defconfig
...
[chomsky@ArcoLinux linux-5.8.3]$ make clean
[chomsky@ArcoLinux linux-5.8.3]$ time(make -j$(nproc))

I think you cleaned the config files before building. Try:

make clean
make mrproper
make defconfig
time(make -j$(nproc))

(You also don’t need to do a make clean if you haven’t built already)

anon13373109 · January 9, 2022, 9:45pm

With this line in my fstab
tmpfs /home/chomsky/ramdisk tmpfs defaults,size=8G 0 0

lunainvictum · January 9, 2022, 9:45pm

Ok. Then try it again on EndeavourOS.

Oh i missed that totaly. @anon13373109 you should try first the “usual way”.

anon13373109 · January 9, 2022, 9:48pm

With ‘usual way’ you mean on the SSD?

lunainvictum · January 9, 2022, 9:49pm

Yes.

EDIT
Oops typo…

EDIT 2

Naah I get the same errors with the time command on my SSD.

anon13373109 · January 9, 2022, 10:10pm

Tried kernel 5-15-13:

real|3m33,014s
user|17m51,274s
sys|1m29,960s

More representable of the shitty i5-9400 14nm++++ I guess

So I guess there was something wrong with de download of kernel 5.8?

EDIT
again in RAM:

real|3m34,337s
|user|17m52,106s
sys|1m30,615s

Apperantly my samsung 970 EVO plus is faster then my RAM

moson · January 9, 2022, 10:23pm

I got odd results with 5.8.3 as well if compile in /tmp (tmpfs) as well actually.

edit

It’s totally weird. I’ve seen 65s, 130s, 170s. On disk it’s always like ~ 170s
Each time doing a full cleanup with make mrproper && make clean…

edit2

Well, yeah, the shit is crashing randomly it seems.
Maybe some quirks with newer compiler versions

After successful compilation you should see at the very end:
Kernel: arch/x86/boot/bzImage is ready (#1)

And you should have a file vmlinux in the directory…
5.15.13 seems to be good btw.

edit3

Indeed that old kernel has issues with newer binutils versions.
