--- Begin Message ---Package: laptop-mode-tools Version: 1.05-1 Severity: normal laptop_mode implements the READAHEAD setting by running blockdev with the --setra option for each block-device underlying a mounted file-system. This in turn appears to use the BLKRASET ioctl. In Linux 2.6 this ioctl this has the desired effect. In Linux 2.4 it appears to set the number of blocks to read-ahead on the *device* as opposed to within a *file*, and the maximum value of this number is 255. As a result the invocation of blockdev will fail on Linux 2.4 for any usefully large value of READAHEAD, and will not in any case have the desired affect for fragmented files. Unhelpfully, laptop_mode redirects its error message to /dev/null so this is not reported anywhere. laptop_mode should instead use the BLKFRASET ioctl, which is the same as BLKRASET on 2.6 and also works properly on 2.4 for IDE devices (but unfortunately no others). If there is no command that exposes this ioctl, laptop_mode could instead write this setting through the /proc filesystem: # Find the major device name and test whether it's IDE. read major minor < <(stat -c "0x%t 0x%T" "$DEV") major_name="$(awk "BEGIN { block=0 }; /^Block / { block=1 }; /^ *$(($major))/ { if (block) print \$2 }" /proc/devices)" if [ "x${major_name#ide}" != "x$major_name" ]; then # Find the device's settings file. if [ $(($minor)) -lt 64 ]; then drive_letters=acegikmoqsuwy else drive_letters=bdfhjlnprtvxz fi drive_settings=$(echo /proc/ide/$major_name/hd[$drive_letters]/settings) if [ -f "$drive_settings" ]; then echo file_readahead:$READAHEAD >$drive_settings else : # TODO: log error fi else : # TODO: log error fi (This obviously only works for IDE devices, so should be used only under 2.4 where there is no better alternative.) -- System Information: Debian Release: 3.1 APT prefers unstable APT policy: (500, 'unstable') Architecture: i386 (i686) Kernel: Linux 2.4.27-2-686 Locale: LANG=en_GB.UTF-8, LC_CTYPE=en_GB.UTF-8 (charmap=UTF-8) Versions of packages laptop-mode-tools depends on: ii powermgmt-base 1.22 Common utils and configs for power -- no debconf information
