Hello,
This patch adds powerpc host support to the CONFIG_MMU_MAP patch
written by Piotrek. My patch should be applied on top of
v1-part[1-3].patch.gz. I have only tested the code with a x86 guest on
a ppc host running Linux - someone, please test on a host running OSX.
Performance gain reported by nbench:
Memory index: 50%
Integer index: 44%
Fp index: 4%
Right now each map-memory access consists of 5-6 powerpc instructions.
If a direct pointer to mem_map could be kept in a register then we
would be down to 3-4 instructions per memoy access...
