SubjectRecommended driver for current AMD processors
Date
Dear Linux folks,


What driver is recommended for current AMD Ryzen based processors
like *AMD Ryzen 5 PRO 1500 Quad-Core Processor* or *AMD EPYC 7601
32-Core Processor*?

Only from the acpi-cpufreq Kconfig description, I assume, that that
driver should be used.

Would a “native” driver like Intel’s P state driver also give better
results? Do you know if AMD is working on something like that?



Kind regards,
