UCODEADM(1M)UCODEADM(1M)NAMEucodeadm - update processor microcode
SYNOPSIS
/usr/sbin/ucodeadm -v
/usr/sbin/ucodeadm -umicrocode-text-file
/usr/sbin/ucodeadm -i [-R path] microcode-text-file
DESCRIPTION
The ucodeadm utility can be used to report running microcode revision
on the processors, update microcode, or install microcode on the target
system to be used during the boot process.
The microcode-text-file can be obtained from processor vendors.
OPTIONS-v
Report microcode revision.
-u microcode-text-file
Update microcode on all cross-call interrupt
ready processors.
-i microcode-text-file
Install microcode files on target system to
be used during the next boot cycle. The text
file name must have the vendor name prefix,
such as "intel" or "amd".
By default the microcode files will be
installed at:
/platform/i86pc/ucode/$VENDORSTR/
where VENDORSTR is either "GenuineIntel" or
"AuthenticAMD".
-R alternate path
Install microcode path in the alternate path.
EXAMPLES
Example 1 Reporting the Microcode Revision
The following example displays the microcode revision that is currently
running:
# ucodeadm-v
Example 2 Updating the Processor Microcode
The following example updates the processor microcode to intel-
ucode.txt:
# ucodeadm-u intel-ucode.txt
Example 3 Installing the Microcode on the Target System
The following example installs the microcode on the target system,
/export/ucode-path:
# ucodeadm-i -R /export/ucode-path intel-ucode.txt
If an alternate path is used when installing the microcode on the tar‐
get system, the installed microcode file is not used on the next boot
cycle.
EXIT STATUS
The following exit values are returned:
0
Successful completion.
>0
An error occurred.
