We are working on 2.6.35.9 linux kernel on MIPS 34kce core and our cache is VIVT having cache aliasing .
No, they're VIPT unless you successfully modified your 34K core to change it from a less than perfect cache design to the most lunatic cache policy known to man kind ...
When I check the implementation on ARM I can check the implemenation exists , but there is not similar implementation exists on MIPS. These API's are used by XFS module: static inline void flush_kernel_vmap_range(void *vaddr, int size) static inline void invalidate_kernel_vmap_range(void *vaddr, int size) static inline void flush_kernel_dcache_page(struct page *page)
A known problem for (too ...) long. I'll finally take care of it. Ralf
