/usr/sbin/ucodeadm -v
/usr/sbin/ucodeadm -umicrocode-text-file
/usr/sbin/ucodeadm -i [-R path] microcode-text-file
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.
-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.
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 target system, the installed microcode file is not used on the next boot cycle.
The following exit values are returned:
0
Successful completion.
>0
An error occurred.
