Disable self-snoop on Intel CPUs

Disable self-snoop on Intel CPUs

Hi everyone,

     I read from the following post that self-snooping feature can be disabled manually, but I could not find any way to accomplish this from any official document. Do anyone kown about how to do this?

    Additionally, It seems that instruction cache snooping can be disabled on the Intel® Xeon Phi™ Coprocessor.

 Thanks in advance.
