>Description:
The SS5/70 has these attributes for the CPU:
...
cache-line-size 00000020
cache-nlines 00000200
page-size 00001000
dcache-line-size 00000010
dcache-nlines 00000200
dcache-associativity 00000001
icache-line-size 00000020
icache-nlines 00000200
icache-associativity 00000001
ncaches 00000002
mmu-nctx 00000100
...
And the SS5/170 has these attributes for the CPU:
...
ecache-line-size 00000020
ecache-nlines 00004000
ecache-associativity 00000001
dcache-line-size 00000020
dcache-nlines 00000200
dcache-associativity 00000001
icache-line-size 00000020
icache-nlines 00000200
icache-associativity 00000001
ncaches 00000002
mmu-nctx 00000100
...
dcache = data cache
icache = instruction cache
ecache = external (L2) cache (?)
cache = external (L2) cache (?)
Whilst NetBSD reports the instruction/data cache properly, it
seemingly ignores the `cache' on the ss5/70 (I'll update this
with the results of booting netbsd on the ss5/170 later).
