Hello, regarding https://bugs.launchpad.net/baltix/+bug/930447 i´m trying to make a simple and tiny kernel patch which let`s you add "fixpae" to the kernel commandline. i`m a rather bad programmer and do not really have a clue about kernel programming, but i think trying to fix this issue at the kernel level, to be included at least in distro`s kernel who ship only pae enabled kernels nowadays is a good approach and chances for inclusion are high - so i thought i give it a try. the mentioned param should 1. make validate_cpu() call being skipped in arch/x86/boot/main.c 2. add "pae" string to the flags line in /proc/cpuinfo The first one was easy - just add one if/else with cmdline_find_option_bool("fixpae") and you´re done. That one actually works, forcing the kernel to boot instead of stopping with a message about missing pae support (which is wrong on some cpu`s). The second one seems a little bit more difficult, i find no example (one that i understand) how to parse a boolean kernel commandline option at "non early boot stage". It seems i cannot use the early commandline parser, so how is that being done in arch/x86/kernel/cpu/proc.c ? regards roland _______________________________________________ Kernelnewbies mailing list Kernelnewbies@xxxxxxxxxxxxxxxxx http://lists.kernelnewbies.org/mailman/listinfo/kernelnewbies
