Subject: flush_cache_page
Date: Sun, 13 Jan 2008 13:55:32 +0900 [thread overview]
Message-ID: <478999C4.3040708@lundman.net> (raw)
Due to cache coherence bugs, Fuse has an extra call to work around it;
flush_cache_page(vma, cs->addr, page_to_pfn(cs->pg));
But my kernel (2.6.15 for mips 4KEc Tangox board) does not have a
flush_cache_page().
If I use kangox_flush_all() Fuse works rather well, but the performance
is abysmal. Can I simulate this call using one of the calls I do have;
__flush_dcache_page
flush_data_cache_page
tangox_flush_cache_all
cache_flush
kc_flush_cache
Or alternatively, does anyone have the source for flush_cache_page() for
said CPU?
