Dear All, We are working on 2.6.35.9 linux kernel on MIPS 34kce core and our cache is VIVT having cache aliasing . 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) I can check implementation on ARM at http://git.kernel.org/?p=linux/kernel/git/longterm/linux-2.6.34.y.git;a=commit;h=252a9afff76097667429b583e8b5b170b47665a4 and ---------------------------------------------------------------------------------------------------------------------------- --- a/arch/arm/include/asm/cacheflush.h+++ b/arch/arm/include/asm/cacheflush.h @@ -432,6 +432,16 @@ static inline void __flush_icache_all(void) : "r" (0)); #endif } +static inline void flush_kernel_vmap_range(void *addr, int size) +{ + if ((cache_is_vivt() || cache_is_vipt_aliasing())) + __cpuc_flush_dcache_area(addr, (size_t)size); +} +static inline void invalidate_kernel_vmap_range(void *addr, int size) +{ + if ((cache_is_vivt() || cache_is_vipt_aliasing())) + __cpuc_flush_dcache_area(addr, (size_t)size); +} ------------------------------------------------------------------------------------------------------------------------------------- http://git.kernel.org/?p=linux/kernel/git/longterm/linux-2.6.34.y.git;a=blobdiff;f=arch/arm/include/asm/cacheflush.h;h=1a711ea8418b6045c581a576caa3f85496ee2673;hp=bb7d695f3900f70d635a3597cd19d7cb68c0d732;hb=73be1591579084a8103a7005dd3172f3e9dd7362;hpb=44b7532b8b464f606053562400719c9c21276037 ====================================================== +#define ARCH_HAS_FLUSH_KERNEL_DCACHE_PAGE +static inline void flush_kernel_dcache_page(struct page *page) +{ + /* highmem pages are always flushed upon kunmap already */ + if ((cache_is_vivt() || cache_is_vipt_aliasing()) && !PageHighMem(page)) + __cpuc_flush_dcache_page(page_address(page)); +} + ========================================================== Is there any similar API exists for MIPS. I want to use for XFS these API's thanks
