Phoronix: Linux 6.13 To Default To AMD P-State Driver For EPYC 9005 CPUs

It was just earlier this week that AMD posted Linux patches to switch EPYC over to using the AMD P-State driver rather than the long-used generic ACPI CPUFreq driver. This should lead to better power efficiency out-of-the-box and is a change being made just for EPYC 9005 "Turin" CPUs and future server processors.

If benchmarking Epyc as it pertains to amd-pstate, you should use the changes queued up for 6.13-rc1. The change to make it default only makes sense because of other changes that are queued up not present in 6.12-rc4 or earlier.
