As for the cachetest program, I think the test program is wrong. It try to mmap offset 0 of a shared file to odd address page with MAP_FIXED. It means "I want non-coherent mapping if dcache alias exists". Currently the kernel surely gives what the program want. The kernel might have to return EINVAL in such case, but I'm not sure which is the right behavior. Please look at David S. Miller's comments, for example, http://lkml.org/lkml/2003/9/1/48 --- Atsushi Nemoto
