To find what has changed in the latest kernel, run + + ./check_module_list.pl /path/to/kernel-desktop-<version>.rpm + +This will extract information about the available kernel modules from the +RPM file and print a report to stdout. The report is in two parts. + +The first part filters the list of kernel modules to find drivers we are +interested in (pci/usb/firewire/pcmcia/dmi/acpi/hid/serio/mdio) and prints +a single line for each such module. If the module is already listed in +list_modules.pm, the line is prefixed by "#". The remainder of the line +contains the module path (relative to the root of the kernel source tree) +the module file name (excluding the .ko.xz suffix), and either the category +the module is listed under in list_modules.pm or, if the module is not already +listed, the module description. + +The second part lists each module that is already listed in list_modules.pm +and prints a single line for each such module. If the module is one of the +drivers listed in the first part of the report, the line is prefixed by "#". +If the module is a built-in module, the line is prefixed by "=". If the +module is not in the list of kernel modules obtained from the RPM, the line +is prefixed by "!". + +The upshot of this is that any lines prefixed by "#" can be ignored. Lines +prefixed by "!" represent modules listed in list_modules.pm that no longer +exist in the kernel (either because they've been renamed or because they are +obsolete). In the first part of the report, lines with no prefix represent +driver modules that could potentially be added to list_modules.pm, but this +will require some judgement on the part of the user. In the second part of +the report, lines with no prefix represent non-driver modules. These will +be modules that are included in the installer stage 1 image, but there is +no obvious way to check which ones are really needed. + +The output from check_module_list.pl after updating list_modules.pm should +be saved in check_module_list.rpt for reference when next updating. + +After updating the module lists in list_modules.pm, running + + perl -I. modules.pm check <kernel-version> + +will check whether there are any modules listed in pcitable.gz pr usbtable.gz +in /usr/share/ldetect-lst that are not also listed in list_modules.pm. The +specified kernel version needs to be installed on the system for this to work. +If <kernel-version> is omitted, the currently running kernel version will be +used. 'make check' will run this. |
