Hi again I trying to understand how the different mem*() and *_page() functions in arch/ppc/kernel/misc.S and arch/ppc/lib/string.S works wrt data cache.
I found that on 8xx these are not used. Why? Are there 8xx variants that can't handle them? Do 860 work with these? Also, why is not dcbtst(write a cache line) used in the different copy functions, copy_page()for example, instead of the COPY_16_BYTES macro? Jocke ** Sent via the linuxppc-embedded mail list.
