I did. the internal isram_read and isram_write functions operate on complete cache lines. the isram_memcpy() functions at the byte level, and there is no need for alignment. -Robin BTW - arch/blackfin/mm/isram-driver.c:isram_check_addr() looks like another place for bfin_mem_access_type() (if it not BFIN_MEM_ACCESS_ITEST, return false)... -Robin _______________________________________________ Linux-kernel-commits mailing list [email protected] https://blackfin.uclinux.org/mailman/listinfo/linux-kernel-commits
