I am getting really confused. :-/ Why on this PC the MICROCODE options become available only when I enable INITRD, but on other PCs such a problem does not exist? -- Regards, Mick signature.asc Description: This is a digitally signed message part.

What happens if you set this; does MICROCODE appear then? This is odd, because I see this, searching from the /usr/src/ directory: peak src # grep MICROCODE linux-4.4.6-gentoo/.config # peak src # grep MICROCODE linux-4.4.7-gentoo/.config CONFIG_MICROCODE=y CONFIG_MICROCODE_INTEL=y # CONFIG_MICROCODE_AMD is not set CONFIG_MICROCODE_OLD_INTERFACE=y peak src # grep MICROCODE linux-4.5.0-gentoo-r1/.config # peak src # grep MICROCODE linux-4.5.1-gentoo/.config CONFIG_MICROCODE=y CONFIG_MICROCODE_INTEL=y # CONFIG_MICROCODE_AMD is not set CONFIG_MICROCODE_OLD_INTERFACE=y So the rules seem to change with succeeding versions of the kernel. Not sure what to suggest here. (I've been playing with lots of versions of kernel, boinc, virtualbox and others recently, which is why I still have those kernel sources installed. I've compiled and booted all of them at various times.) -- Rgds Peter

It takes me to level 0 of menuconfig, with "Processor type and features --->" highlighted. Ditto when I press 3, which is Intel Microcode module. :-/ -- Regards, Mick signature.asc Description: This is a digitally signed message part.

You should use the search option in make menuconfig. If th eoption you want does not show up in .config, you are probably missing one of the options it depends on.

[gentoo-user] Where is CONFIG_MICROCODE gone in kernel 4.4.6-gentoo?
I seem to have mislaid my microcode somewhere, in the latest stable gentoo kernel: # grep -i MICROCODE .config # As a result I get this during boot: # /etc/init.d/microcode_ctl start * Updating microcode ... microcode_ctl: cannot open /dev/cpu/microcode for writing errno=2 (No such file or directory) * Failed to update microcode via '/dev/cpu/microcode' [ !! ] * ERROR: microcode_ctl failed to start The previous kernel contained this: # grep -i MICROCODE /boot/config-4.1.15-r1-gentoo CONFIG_MICROCODE=y CONFIG_MICROCODE_INTEL=y # CONFIG_MICROCODE_AMD is not set CONFIG_MICROCODE_OLD_INTERFACE=y Is there something else I ought to switch on first? -- Regards, Mick signature.asc Description: This is a digitally signed message part.
