28 The \fBucodeadm\fR utility can be used to report running microcode revision on
29 the processors, update microcode, or install microcode on the target system to
30 be used during the boot process.
33 The \fImicrocode-text-file\fR can be obtained from processor vendors.
41 Report microcode revision.
47 \fB\fB-u\fR \fImicrocode-text-file\fR\fR
50 Update microcode on all cross-call interrupt ready processors.
56 \fB\fB-i\fR \fImicrocode-text-file\fR\fR
59 Install microcode files on target system to be used during the next boot
60 cycle. The text file name must have the vendor name prefix, such as
61 "\fBintel\fR" or "\fBamd\fR".
63 By default the microcode files will be installed at:
67 /platform/i86pc/ucode/$VENDORSTR/
72 where \fBVENDORSTR\fR is either "\fBGenuineIntel\fR" or "\fBAuthenticAMD\fR".
78 \fB\fB-R\fR \fIalternate path\fR\fR
81 Install \fImicrocode\fR path in the \fIalternate path\fR.
86 \fBExample 1 \fRReporting the Microcode Revision
89 The following example displays the microcode revision that is currently
101 \fBExample 2 \fRUpdating the Processor Microcode
104 The following example updates the processor microcode to \fBintel-ucode.txt\fR:
109 # ucodeadm -u intel-ucode.txt
115 \fBExample 3 \fRInstalling the Microcode on the Target System
118 The following example installs the microcode on the target system,
119 \fB/export/ucode-path\fR:
124 # ucodeadm -i -R /export/ucode-path intel-ucode.txt
131 If an alternate path is used when installing the microcode on the target
132 system, the installed microcode file is not used on the next boot cycle.
137 The following exit values are returned:
144 Successful completion.
