NAME

ucodeadm - 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 target
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.
