Hi, I read the Intel IA-32 developer's manual recently, and I found the cache lines for L1 and L2 caches in Pentium4 are 64 bytes wide, but the thing make me confused is that the default value CONFIG_X86_L1_CACHE_SHIFT option in 2.4.x kernel is 7, why it's not 6? Any expanation about this would be appreciated! -- Best regards, Michael Chen mailto:[EMAIL PROTECTED] - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
