Kernel compile opts.

[Ragga Muffin <ragga@pyxis23.ec.t.kanazawa-u.ac.jp>]

Hi all,

Can someone shed a light on kernel compile options on a sparc sun_4m ?

Specifically:
I noticed that my kernel (2.2.14) compiles with -no_FPU or such and found
that math_emu.c gets compiled... 
However /proc/cpuinfo says: 

cpu             : Fujitsu  MB86904
fpu             : Lsi Logic/Meiko L64804 or compatible
promlib         : Version 3 Revision 2
prom            : 2.10
type            : sun4m
ncpus probed    : 1
ncpus active    : 1
BogoMips        : 109.77
MMU type        : Fujitsu Swift
invall          : 0
invmm           : 0
invrnge         : 0
invpg           : 0
contexts        : 256

What's the situation here ?

Second: 
What means the option CONFIG_SUN4 ?
There's a warning in the help that says:
"(And the current version will probably work only on sun4/330.)"

And third:
How good is the SUNOS_EMULation ?

TIA for any insights,

RM
