 Posted: Mon Oct 30, 2023 5:25 pm Post subject: Need help with genkernel (Microcode option for Intel) |
 |
|
Hello,
I'm using genkernel to compile the kernel 6.6.0, intended to work on an Intel CPU, but I get the error message
Required kernel option 'CONFIG_MICROCODE_INTEL' which genkernel tried to set is missing!
The config files and output are below, but let me say a few words of my research on this problem.
It looks like that genkernel runs "make menuconfig" (as indicated in genkernel.conf), then successfully adds the line CONFIG_MICROCODE_INTEL=y, then runs "make oldconfig" again, and from that point onwards the newly added line is missing. In order to prove that, I edited the file "/usr/share/genkernel/gen_configkernel.sh", where I added a grep line "grep MICROCODE /usr/src/linux/.config" before and after the final "make oldconfig" and verified that the newly added line is there before, but not after. The line "CONFIG_MICROCODE=y" remains.
I suspect I'm doing something wrong, but I cannot find the error.
Thank you very much in advance!
Kind regards,
Pablo

My coomand line is "genkernel all && emerge @module-rebuild".
The output I get is:

Thank you for the prompt answer.
I modified genkernel.conf not to invoke "make oldconfig", and it works.
Kind regards,
Pablo

Yes, genkernel needs an update.
However, you can use the --no-microcode option to fix this issue:
| Code: |
genkernel --no-microcode --install all
or
genkernel --no-microcode --menuconfig all

Are you sure, that this option is fixing the issue? Or do you assume that this option is fixing the issue?
From "man 8 genkernel":
| Code: | --microcode[=<all|amd|intel>]
Adds early microcode loading support for all, only AMD or Intel processors to kernel
configuration.
--no-microcode
Do not add early microcode loading support to kernel configuration. |
As far as I understand it, the first option is enabling early microcode loading support. But with the kernel 6.6 the way changed, so that genkernel is failing. I assume the goal is to have early microcode loading support enabled. |

No ... and ... No.
It was not Linus who changed this option.
You can have a kernel without a microcode-update even with 6.6 ... just have / give (*) no microcode file when you "make" your kernel 
*) means: You dont configure it == let it empty into CONFIG_EXTRA_FIRMWARE:
| Code: | Device Drivers --->
Generic Driver Options --->
Firmware Loader --->
-*- Firmware loading facility
(intel-ucode/06-5e-03) Build named firmware blobs into the kernel binary |
=>
| Code: | | () Build named firmware blobs into the kernel binary |
(If you are using an initramfs then you simply dont emerge the microcode files; or delete them if you already have it)
The effect of the change is only: IF there is a microcode THEN use it (automatically) WITHOUT the additional need to CONFIGURE the usage (until 6.6 you must configure the usage explicit). |

you take the kernel from the resource kernel.org ? |

| Quote: | | Full sources including the Gentoo patchset for the kernel tree |
For one thing, OpenRC is developed by Gentoo developers and AFAIK it includes some modifications to the kernel.
But this is off topic, so please don't steer the thread away.
Best Regards,
