On PPC870, does the kernel only support 4K pages? To reduce the size of
page table (level & level 2), would 8M page be a better choice on a
custom=20
board? It's a no swap configuration. Memory load is critical in our
design on this project.
Comments?
Thanks,
Atul

The CONFIG_PIN_TLB will get you 8M pages for the kernel
space, and likely be a good solution for you. We have experimented
with various dynamic replace methods for the past several years,
but I still haven't found a solution I like.
