NAME¶

intel-microcode2ucode - convert Intel microcode.dat file into ucode files

SYNOPSIS¶

DESCRIPTION¶

intel-microcode2ucode parses Intel microcode combined text data file (which usually has name microcode.dat) and splits it into individual binary microcode files that can be loaded by the Linux kernel.

Generated microcode files are placed into intel-ucode directory, which is created in the current working directory, and have file name format of FF-MM-SS, where FF is the CPU family number, MM is the model number, and SS is stepping. All three values are zero-filled to two digits and are hexadecimal (letters are in the lower case).

This tool is mostly of historic interest, as Intel ships separate microcode files now.

OPTIONS¶

MICROCODE_FILE

Path to the microcode.dat file. If no path has been provided, the default path /lib/firmware/microcode.dat is used. If - (single dash) is provided as an argument, data is read from the standard input.

EXIT STATUS¶

0

Success.

1

Error occurred: temporary buffer cannot be allocated, input microcode file cannot be opened, microcode version and/or format are unknown, cannot open output file, cannot write to the output file.
