I'm currently trying to get kernel 2.6.8 running on a Casio BE-300, a
NEC VR4131 (rev1.2) based PDA.
I noticed a (for me) strange result when comparing 2.4 with 2.6, please
have a look at the linesize below:
CPU revision is: 00000c80
Primary instruction cache 16kb, linesize 32 bytes.
Primary data cache 16kb, linesize 16 bytes.
Primary instruction cache 16kB, physically tagged, 2-way, linesize 16
Primary data cache 16kB 2-way, linesize 16 bytes.
Any idea why the reported icache linesize is different between2.4 and
2.6 ? Which one should I trust ?
and from the original botloader it looks like at boot config is set to:
# [4 ] DB: 0= data cache refill size=4 words
# [5 ] IB: 1=instruction cache refill size=8 words
# [6-8 ] DC: 100= data cache size, 16K
# [9-11 ] IC: 101= instruction cache size, 16K.
Is it common to have different dcache/icache refill sizes ?
Thanks for your time,
