Problems with launch on i7-10700

[InvaderDolan]

Hi there! First of all, I really like CoreFreq, it's the only way to check RAM timings. I appreciate it. I have successfully installed the CoreFreq on 4 different machines with R9 5950X (3 x Gigabyte B550 Aorus Master + 1 x ASUS ROG X570-E), on 5.11 kernel. And they're working like a charm. But I have a problem on machine with i7-10700 (MSI MAG Tomahawk B450) on 5.13 kernel. Here is the output when I make:

Skipping BTF generation for /home/invader/CoreFreq/corefreqk.ko due to unavailability of vmlinux
make[1]: Leaving directory '/usr/src/linux-headers-5.13.0-28-generic'

After this build, I do sudo insmod corefreqk.ko, sudo ./corefreqd and then ./corefreq-cli, after that nothing happens, just insertion point blinks. I see the problem: Skipping BTF generation for /home/invader/CoreFreq/corefreqk.ko due to unavailability of vmlinux but couldn't fix it after googling. I am pretty sure that the CoreFreq will work on 5.11 kernel because one of the machines on 5950X didn't work on 5.13 as well. But how can I fix it without changing kernel?

Thank you for your attention.

Hello,

Thanks a lot for using CoreFreq I've also no clue about this message, and after Googling found this answer which use dkms

EDIT: Others are also talking about signed driver missing If your system claims this, disable SECURE BOOT in BIOS

But i7-10700 of Comet Lake may also not enough be implemented. I just have received two of this architecture. See i5-10400 and i5-10600 in Wiki Can you check the kernel log for any driver error or crash ? and post the callflow and registers trap if any ?

Are you still struggling with the issue ? Is Secured Boot the root cause ?
