Just noticed this in "include/asm-i386/processor.h" :
--- snip ---
/* Prefetch instructions for Pentium III and AMD Athlon */
#ifdef CONFIG_MPENTIUMIII
#define ARCH_HAS_PREFETCH
extern inline void prefetch(const void *x)
{
__asm__ __volatile__ ("prefetchnta (%0)" : : "r"(x));
}
#elif CONFIG_X86_USE_3DNOW
--- end snip ---
The P4 has SSE and prefetch or no ?
