Hi all,
is there an easy way to check if the caches are all enabled ?
I have some performance problems and I'm trying to figure out
where it is coming from ...

cheers & thanks

Hi Emanuel,

Without the MMU on, please check the ICCI and DCCI registers.
These give 128 MB resolution.

With the MMU on, caching is on a per-page basis; check the
TLB_W and TLB_I flags of each TLB entry.
