Intel Microcode Update Utility for Linux
|
|
|
|
The microcode_ctl utility is a companion to the IA32 microcode driver written
|
|
by Tigran Aivazian <tigran@aivazian.fsnet.co.uk>. The utility has two uses:
|
|
|
|
* It decodes and sends new microcode to the kernel driver to be uploaded
|
|
to Intel IA32 processors. (Pentium Pro, PII, PIII, Pentium 4, Celeron,
|
|
Xeon etc - all P6 and above, which does NOT include pentium classics).
|
|
It also supports processors of the x86_64 architecture.
|
|
* It signals the kernel driver to release any buffers it may hold.
|
|
|
|
The microcode update is volatile and needs to be uploaded on each system
|
|
boot i.e. it doesn't reflash your cpu permanently, reboot and it reverts
|
|
back to the old microcode.
|
|
|
|
To use this utility you need to compile the kernel driver (found under
|
|
"Processor type and features"). The microcode itself can be found at
|
|
http://downloadcenter.intel.com/default.aspx and should be placed under
|
|
/lib/firmware/microcode.dat. Alternatively (or preferably) you can use
|
|
the *intel-microcode* SlackBuild available at slackbuilds.org to prepare
|
|
the microcode package to be readily used with the microcode_ctl utility.
|
|
|
|
To have the microcode updated each time at boot, start the included
|
|
init script from /etc/rc.d/rc.local:
|
|
|
|
if [ -x /etc/rc.d/rc.microcode_ctl ]; then
|
|
/etc/rc.d/rc.microcode_ctl start
|
|
fi
