The bug is potentially in all cores with cpuid 670->68F If you have it, and you're not running a kernel with the fix you'll see you have a 16MB cache. If you run a kernel with the fix, you'll have the correct size (64KB) > Does anyone recall where exactly are the Cyrix II L2 > cache bug fix in the kernelso that I can experiement > them toward the Cyrix III? arch/i386/kernel/setup.c display_cacheinfo() -- | Dave Jones. http://www.codemonkey.org.uk | SuSE Labs - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
