Ralf,
thanks for the detailed information.

Basically our target has a MIPS24KE host processor on
which Linux runs and a networking processor (NP) which
sits between the EMAC contoller

Hi Geert,
Thanks for your repsonse.
In linux-2.6.18 (for MIPS24KE processor):
suppose if i want to do flush only then which API i
should use?
Similarly, if i want to do invalidation only which API
i should use?
Thanks again.
Regards,
Veerasena.

hi Geert,
here i mean 'flush' is 'write-back only'

Hi Ralf,
Thanks for the reply.
Is there any problem if we use the below API's in
linxu-2.6.18
- dma_cache_wback_inv()
- dma_cache_wback()
- dma_cache_inv()
functionality wise, especially in r4k.c i dont see any
difference between the implementation of these APIs.
Can we apply the 2.6.24

`flush' is fuzzy terminology: some people mean invalidate, others mean
write back, others mean both.

Hi,
I have ported Linux-2.6.18 kernel on MIPS24KE
processor. I am using write back cache policy.
Could you please guide me under what cases the below
cache API's are being used:
- dma_cache_wback_inv() : Could you explain what
exactly this function does
- dma_cache_wback() : This function write
