Powernow is for cpufreq (a good thing to use, IMHO, but not mentioned in LFS) and not used anymore for K10 and newer CPUs (the support is now in acpi-cpufreq). From memory, the initial K10 was the athlon64xII. My git-foo isn't good enough to identify which release that happened in, but the indications are that it was well before 3.10. SMP is the key. If Dan is building only for that machine (and doesn't intend to use the system to boot any replacement machine when the time comes) then optimizing for the specific processor family, i.e. AMD x86_64 (Opteron/Athlon/Hammer/K8 : this is CONFIG_MK8 but works on K10 ;-) might gain a little, as might Multi-Core Scheduler support. ĸen -- das eine Mal als Tragödie, dieses Mal als Farce -- http://linuxfromscratch.org/mailman/listinfo/lfs-support FAQ: http://www.linuxfromscratch.org/lfs/faq.html Unsubscribe: See the above information page
