    Disable hardware prefetcher on SNB?

    wujj123456

      I want to quantify the effect of HW prefetcher on an SNB processor.  I flipped through the Software Developer's Manual, but I only found MSR for Core 2 Arch.  The same 0x1A0 and bit 9, 19, 37, 39 doesn't work on my SNB processor. 

       

      I wonder if there is a way to turn of hardware prefetcher in SNB as I can do in Core 2?  Thanks.

       

      Btw, if someone knows the answer, you might as well answer this related thread for Nehalem: prefetch disable via MSRs on Nehalem?
