https://bugzilla.kernel.org/show_bug.cgi?id=19702 --- Comment #46 from Peter Ganzhorn <peter.ganzhorn@xxxxxxxxxxxxxx> 2010-11-08 12:32:34 --- Concerning the changes to arch/x86/kernel/include/asm/cpufeatures.h: I can't just kill the line #define X86_FEATURE_APERFMPERF (3*32+28) /* APERFMPERF */ since this will prevent the kernel from being compiled. For now I changed the line to #define X86_FEATURE_APERFMPERF (6*32+11) /* APERFMPERF */ which changes the checked feature to SSE5 instead of AMPERF - my CPU does not support SSE5 and this should report a non-set bit. Not the most elegant solution and of course not really portable to newer cpus, but it sure does the trick. Do you have a better idea to hard-code that feature to zero in the kernel code? Is there a CPUID bit that's 0 by default for all processors? I looked at related kernel code, but I don't think there's an easier or better fix at another place in the code, as the way I choose to go makes the feature reported as non-present for all code in the kernel. -- Configure bugmail: https://bugzilla.kernel.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug. -- To unsubscribe from this list: send the line "unsubscribe cpufreq" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
