[Intel][12th][13th] L2 Adaptive Multipath Probability prefetcher

[cyring]

I would like to add a new feature L2 AMP Prefetcher in the Technologies window

Can anyone with such processor toggle bit 5 (AMP_PREFETCH_DISABLE) of MSR 0x1A4 and verify if it impacts performance ?

Observe you will have to rdmsr and wrmsr the register on a P-Core.
Use the topology provided by CoreFreq to find out the CPU number of Performance Cores.

Intel AMP has been programmed into the development branch

Since Alder Lake Processors, you should be able to toggle the feature.

Mine being to old to support that register bit, please tell me about your results.
Your screenshots are welcome.
