intel-microcode: a recipe for Intel microcode datafile
This recipe provides the microcode datafile for Intel Processors. The recipe provides: 1. microcode.dat file for microcode updating from user space with the iucode-tool utility. 2. the microcode cpio file which gets bundled with the initrd to support microcode loading at early boot time.

3DESCRIPTION = "The microcode data file contains the latest microcode\
4 definitions for all Intel processors. Intel releases microcode updates\
5 to correct processor behavior as documented in the respective processor\
6 specification updates. While the regular approach to getting this microcode\
7 update is via a BIOS upgrade, Intel realizes that this can be an\
8 administrative hassle. The Linux operating system and VMware ESX\
9 products have a mechanism to update the microcode after booting.\
10 For example, this file will be used by the operating system mechanism\
11 if the file is placed in the /etc/firmware directory of the Linux system."
