Noah Goldstein 180897c161 x86: Make the divisor in setting non_temporal_threshold cpu specific ... Different systems prefer a different divisors. From benchmarks[1] so far the following divisors have been found: ICX : 2 SKX : 2 BWD : 8 For Intel, we are generalizing that BWD and older prefers 8 as a divisor, and SKL and newer prefers 2. This number can be further tuned as benchmarks are run. [1]: https://github.com/goldsteinn/memcpy-nt-benchmarks Reviewed-by: DJ Delorie <dj@redhat.com>		2023-06-12 11:33:39 -05:00
