This port includes an RC script, which is one of two methods to update
|
|
the CPU microcode on a FreeBSD system.
|
|
|
|
1. The first method does not require the RC script included here and is
|
|
only supported with Intel processors. It is the preferred method,
|
|
because it ensures that any CPU features introduced by a microcode
|
|
update are visible to the kernel by applying the update before the
|
|
kernel performs CPU feature detection.
|
|
|
|
To enable updates using the first method, add the following lines to
|
|
/boot/loader.conf:
|
|
|
|
cpu_microcode_load="YES"
|
|
cpu_microcode_name="/boot/firmware/intel-ucode.bin"
|
|
|
|
The microcode update will be loaded when the system is rebooted.
|
|
|
|
|
|
2. The second method, which uses the RC script included here, can be
|
|
enabled by adding the following line to /etc/rc.conf:
|
|
|
|
microcode_update_enable="YES"
|
|
|
|
The microcode update is then applied upon reboot or when the microcode
|
|
update service is run via:
|
|
|
|
# service microcode_update start
|
|
|
|
If the CPU requires a microcode update, a console message such as the
|
|
following will appear:
|
|
|
|
Updating CPU Microcode...
|
|
%%DATADIR%%/m32306c3_00000022.fw: updating cpu /dev/cpuctl0 from rev 0x17 to rev 0x22... done.
|
|
%%DATADIR%%/m32306c3_00000022.fw: updating cpu /dev/cpuctl2 from rev 0x17 to rev 0x22... done.
|
|
%%DATADIR%%/m32306c3_00000022.fw: updating cpu /dev/cpuctl4 from rev 0x17 to rev 0x22... done.
|
|
%%DATADIR%%/m32306c3_00000022.fw: updating cpu /dev/cpuctl6 from rev 0x17 to rev 0x22... done.
|
|
Done.
|
|
|
|
It is safe to enable both methods.
