Can you please try to build against the current master version ? This would be version 1.96.0

cyring · 2023-04-27T14:09:08Z

Also if compiling Linux Kernel and CoreFreq with clang/llvm, check for CONFIG_FORTIFY_SOURCE fixed in this post

cyring · 2023-04-29T00:34:00Z

Using linux-cachyos 6.3.0-5
built with _makemenuconfig=y _use_llvm_lto=full makepkg -sfir
I have successfully compile CoreFreq 1.96.0
with make CC='clang' LLVM=1 clean all
and run:

LethalManBoob · 2023-05-01T09:23:06Z

Good new is it works now but..

LethalManBoob · 2023-05-01T09:27:19Z

Also i seem to be unable to register the cpu idle driver but maybe i followed somthing wrong so if you can drop somthing here to help me that would be appreicated.

cyring · 2023-05-01T09:58:35Z

Does your kernel log (dmesg) show any crash ?

Can you validate Processor with CoreFreq + ArchLinux from Live-CD ? Please take a picture.

cyring · 2023-05-02T21:20:15Z

Do you still have an issue to start CoreFreq ?

LethalManBoob · 2023-05-04T21:44:18Z

Okay so i was delayed but ill post the dmesg tomorrow.

LethalManBoob · 2023-05-05T06:56:52Z

LethalManBoob · 2023-05-05T06:57:50Z

also the daemon wont start on its own. i have to manually allow it to start every time.
I was told it requires me to make a modprobe file that calls for corefreqk to run but thats all i know.

cyring · 2023-05-05T13:10:51Z

No sign of crash in log above.

Procedure to run CoreFreq

Right after booting, starts CoreFreq this way:

Go to the source directory where you have downloaded latest 1.96 version, and fully rebuild:

make clean all CC='clang' LLVM=1 ## for your CachyOS LTO setup

Load Driver as root

insmod ./corefreqk.ko
lsmod|grep corefreq ## you should see kernel module of CoreFreq

Starts Daemon as root

./corefreq -d ## one thread per CPU is listed

Starts Client as a user

./corefreq-cli

Does it work ?

If not, please reboot to mainline Linux kernel, not CachyOS.
But simply build with gcc this time:

make clean all CC=gcc

Go back to step 2

Please see #435 (comment) how CachyOS is built

LethalManBoob · 2023-05-05T20:52:07Z

Look like a high change that lto now breaks it. the corefreq-cli works when build from source

LethalManBoob · 2023-05-05T20:57:44Z

okay so when i install from aur...

Wrapping up now

Thin LTO does not work with CoreFreq

LethalManBoob · 2023-05-06T08:24:13Z

I am currently on the non lto version but it still gives me the error I said above when trying corefreq-cli

cyring · 2023-05-06T08:36:43Z

I am currently on the non lto version but it still gives me the error I said above when trying corefreq-cli

Based on #435 (comment) and #435 (comment) it's hard to imagine what's going on your system.

There's only one way to make CoreFreq works; It has to successfully startup in that order:

Driver
Daemon
Client

So I would like you to run CoreFreq with the mainstream Linux kernel and gcc ; no CachyOS flavor of whatever, no patch.
Please let me know if it successfully starts and we can validate first there is no hardware issue to support your processor.
Thank you.

cyring · 2023-05-10T23:22:50Z

Did you make the test requested above ?
