After 10 years, I've upgraded my desktop hardware from an Intel I7-4790 to an AMD 7950X. According to the handbook, updating firmware/microcode on the AMD platform requires an initramfs. Okay, this is new to me, but following this article: https://wiki.gentoo.org/wiki/Project:Distribution_Kernel#Modifying_kernel_configuration I have a working system. BUT, every time I walk away, the system goes int hibernate/suspend and won't 'recover' when I return. Even though I've created a kernel config (and saved that config) when I rebuild the kernel, it fails to use the 'saveconfig!'

As you can see from the code snipped, I've just rebuilt the kernel with the 'savecconfig' flag set, but the resultant kernel still shows CONFIG_SUSPEND set - even though the gentoo-kernal has CONFIG_SUSPEND unset.
What am I doing wrong???

dpshak,
I'll bite ...
Your running kernel was built at | Code: | | Sun Jan 19 23:38:06 CST 2025 |
You have a newer kernel in /boot | Code: | | rw-r--r-- 1 root root 20337152 Jan 20 17:23 vmlinuz-6.12.10-gentoo-dist |
so its not yet in use.
It follows that you are not running the kernel you think you are. Probably because its not grubs default choice.
Its possible to build the CPU microcode into the kernel, or put it into its own initrd too.When you have several initrds, they are all loaded and used.

I would try to boot the newest kernel just to be sure, but I believe this is to show the config from the newest kernel | Code: | main /boot # date
Mon Jan 20 17:24:36 CST 2025
main /boot # egrep CONFIG_SUSPEND config-6.12.10-gentoo-dist
CONFIG_SUSPEND=y
CONFIG_SUSPEND_FREEZER=y
# CONFIG_SUSPEND_SKIP_SYNC is not set |
where it presumely reset itself to CONFIG_SUSPEND=y - disregarding in the savedconfig
Was the latest iteration of the kernel build with savedconfig use-flag? needs to be, to pick up the saved config afaik |

Tangential, an initramfs isn't required. You can store the microcode blobs in the kernel with the kernel's CONFIG_EXTRA_FIRMWARE option. |

You may be right, that's what it looks like, but by the time I posted I was frustrated as hell! I'd tried everything I could think of to make it work, with no luck. What prompted me to get into this was that CONFIG_SUSPEND. Everytime I'd walk away from the machine, it would suspend and then I'd have to reboot to get it running again. Everytime I'd reboot it, I would remove the '6.12.10' stuff from /boot and try something different. I probably lost track of what I'd done... I've never used an initrds before. With the older Intel chips, I've always done the early microcode loading, so this was all new to me! However, with the amount of microcode and firmware loaded for this board, i'll probably just leave well enough alone. What I finally did, to solve my problem (I don't know if it's the 'right' way, or not, but it works) was to go to /usr/src/linux (linux was linked to 6.12.10 source) made my changes to the config and saved it to /etc/portage/savedconfig/sys-kernel/gentoo-kernel and gentoo-kernel-6.12.10. SUCCESS!

Yes it was. I made the mistake, on one iteration of this experiment, of unsetting the savedconfig flag. What I found that solved my issue, as I said to NeddySeagoon, was to make my config changes in /usr/src/linux and copy that .config to /etc/portage/savedconfig/sys-kernel/gentoo-kernel and gentoo-kernel-6.12.10. It's now working!

Thank you! That's what I used to do with that old I7. That old I7 had 2 microcode blobs. The AMD has 2 microcode blobs and a whole stack of firmware blobs! I think I'll stick with the initrds! |
