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.

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