There are CPUs (at least some version of Alpha, 21064 IIRC) that uses flush upon L1 read miss, so they do not snoop their local WB. IIRC P5 has internal and external snooping while P6, using a write allocate L1, does not have external snooping. - Davide - 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/ | ||||||||||
