 Hi All,
Pls note that I have a M9K MCU board with 2 x  3.0GHzSPARC64 VII+ CPU Module Installed.  According to the FE handbook, the Cache size for this CPU should be 12MB.  How come it only show 6MB from the prtdaig output:

$ /usr/platform/sun4u/sbin/prtdiag -v | less
System Configuration:  Oracle Corporation  sun4u SPARC Enterprise M9000 Server
System clock frequency: 960 MHz
Memory size: 81920 Megabytes
