This patch enables NAND subpage read functionality. If upper layer drivers are requesting to read non page aligned data NAND subpage-read functionality reads the only whose ECC regions which include requested data when original code reads whole page. This significantly improves performance in many cases. Here are some digits : UBI volume mount time No subpage reads: 5.75 seconds Subpage read patch: 2.42 seconds Open/stat time for files on JFFS2 volume: No subpage read 0m 5.36s Subpage read 0m 2.88s Signed-off-by Alexey Korolev <akorolev@infradead.org> Acked-by: Artem Bityutskiy <dedekind@infradead.org> Acked-by: Jörn Engel <joern@logfs.org> Signed-off-by: David Woodhouse <David.Woodhouse@intel.com> |
