.fi
.SH DESCRIPTION
.sp
.LP
The \fBucodeadm\fR 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.
.sp
.LP
The \fImicrocode-text-file\fR can be obtained from processor vendors.
.SH OPTIONS
.sp
.ne 2
.na
\fB\fB-v\fR\fR
.ad
.RS 26n
Report microcode revision.
.RE
.sp
.ne 2
.na
\fB\fB-u\fR \fImicrocode-text-file\fR\fR
.ad
.RS 26n
Update microcode on all cross-call interrupt ready processors.
.RE
.sp
.ne 2
.na
\fB\fB-i\fR \fImicrocode-text-file\fR\fR
.ad
.RS 26n
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
"\fBintel\fR" or "\fBamd\fR".
.sp
By default the microcode files will be installed at:
.sp
.in +2
.nf
/platform/i86pc/ucode/$VENDORSTR/
.fi
.in -2
.sp
where \fBVENDORSTR\fR is either "\fBGenuineIntel\fR" or "\fBAuthenticAMD\fR".
.RE
.sp
.ne 2
.na
\fB\fB-R\fR \fIalternate path\fR\fR
.ad
.RS 26n
Install \fImicrocode\fR path in the \fIalternate path\fR.
.RE
.SH EXAMPLES
.LP
\fBExample 1 \fRReporting the Microcode Revision
.sp
.LP
The following example displays the microcode revision that is currently
running:
.sp
.in +2
.nf
# ucodeadm -v
.fi
.in -2
.sp
.LP
\fBExample 2 \fRUpdating the Processor Microcode
.sp
.LP
The following example updates the processor microcode to \fBintel-ucode.txt\fR:
.sp
.in +2
.nf
# ucodeadm -u intel-ucode.txt
.fi
.in -2
.sp
.LP
\fBExample 3 \fRInstalling the Microcode on the Target System
.sp
.LP
The following example installs the microcode on the target system,
\fB/export/ucode-path\fR:
.sp
.in +2
.nf
# ucodeadm -i -R /export/ucode-path intel-ucode.txt
.fi
.in -2
.sp
.sp
.LP
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.
