Hardware Descriptor - M4000/M5000 (OPL)

The gory Hardware details about OPL systems M4000 (FF1) or M5000 (FF2) or
other DC1-3 (Data Center Machines) is described in Hardware descriptor.

Is there is a way to this information, yes of course via the mdb.
Dump the structures (mdb print command)

hwd_header_t
hwd_domain_info_t;
hwd_cpu_t;
hwd_core_t;
hwd_cpu_chip_t;
hwd_sc_t;
hwd_bank_t;
hwd_dimm_t;
hwd_memory_t;

A whole lot of other structures and dump the memory contents and
join togther entire Hardware descriptor.

Wouldn't be easy if there to be command that does the job for you.
Here you go: mdb's dcmd (to read as dee-command) -- oplhwd


Dcmd that I wrote is described here: opl_hwd.c
