Description Harald Hoyer 2015-11-20 08:04:02 UTC

+++ This bug was initially created as a clone of Bug #1278938 +++

On installing rawhide kernels I see: 

Disabling early microcode, because kernel does not support it. CONFIG_MICROCODE_[AMD|INTEL]_EARLY!=y

The kernel options may have changed here so dracut needs to adjust to whatever it is now.

--- Additional comment from Josh Boyer on 2015-11-06 14:30:44 EST ---

This is because of upstream kernel commit fe055896c040df571e4ff56fb196d6845130057b and this hunk of code in dracut:

if [[ $early_microcode = yes ]]; then
    if [[ $hostonly ]]; then
        [[ $(get_cpu_vendor) == "AMD" ]] \
            && ! check_kernel_config CONFIG_MICROCODE_AMD_EARLY \
            && unset early_microcode
        [[ $(get_cpu_vendor) == "Intel" ]] \
            && ! check_kernel_config CONFIG_MICROCODE_INTEL_EARLY \
            && unset early_microcode
    else
        ! check_kernel_config CONFIG_MICROCODE_AMD_EARLY \
            && ! check_kernel_config CONFIG_MICROCODE_INTEL_EARLY \
            && unset early_microcode
    fi
    [[ $early_microcode != yes ]] \
        && dwarn "Disabling early microcode, because kernel does not support it. CONFIG_MICROCODE_[AMD|INTEL]_EARLY!=y"
fi


Since the options no longer even exist in the kernel, they won't show up in the resulting config-<kernel version> installed file even though the functionality is still actually in the kernel.  I've emailed Harald and the upstream author of the kernel patch.

--- Additional comment from Thorsten Leemhuis on 2015-11-19 13:57:52 EST ---

@harald: What's the plan forward here? You afaics fixed it upstream by
http://git.kernel.org/cgit/boot/dracut/dracut.git/commit/?id=875426f2fc1360401ddb5f97c67df031e54958d5 which afaics made it to rawhide already. But everybody that installs a 4.4 kernel in f23 or earlier will get a initramfs without microcode update, which is not a good idea :-/
