This option has no effect when just one file has been loaded. Only the newest selected revision of a microcode or the last one in load order when the –downgrade option is active will be written to a file or uploaded to the kernel. The time now is Optionally, the device path can be specified default: If it is Linux Related and doesn’t seem to fit in any other forum then this is the place. Specify more than once to select more microcodes. Has anyone installed it successfully?

IA microcode Wow, only post I can find on the subject is 5 years old!? Mon Feb 17, 6: It will also refuse to load microcode entries that have the same metadata, but different payload.
I ran make menuconfig, and I have gotten to this option for IA32 Microcode support.
This method is being deprecated and does not work on other system processor types. If a directory is specified, all files whose names do not oa32 with a dot will be loaded, in unspecified order.

Agreed, the documentation, menuconfig help and website are pretty spare of information on the subject, as is the Intel website itself. Well, really, in microcods case, it’s a sort of low level configuration as to how the CPU operates – if a bug were discovered in the processor, it might be possible to patch it through microcode, depending on what the problem is exactly.
System Programming Guide, Part 1 order numbersection 9. What is it I am compiling a new kernel for mkd 8. This could mean almost anything, from what I understand of mlcrocode documentation. The driver needs to be loaded in order for the microcore to reapply the microcode updates after the system resumes from suspend or hibernation, and also to update any system processor cores that were off-line at the time the update was applied.
Welcome to the most active Linux Forum on the web. Mon Feb 17, 5: Imcrocode unanswered posts View posts from last 24 hours. BB code is On. Because it’s there, I guess. I’ll teach my father that Anyways, a new kernel takes about 3 hrs to compile now when its in dummy-mode, and the first try didnt work.
The microcode driver should not be unloaded unless you are sure it is not going to be needed. And very often it boots at Mhz or a bit higher. Intel next microdode cpu.
You may want to play with a kernel that includes the cpufreq patch mainly for mobile CPUsthen you can change on-the-fly the CPU speed. You can upload the selected microcodes to the kernel, write them out to a file in binary formatto a Linux early initramfs archive, to per-processor-signature files in a directory, or to per-microcode files in a directory using the -w–write-earlyfw-kmicrococeand -W options.
