It seems to be the most energy efficient on my lunar lake laptop, having
the lowest low-utilization power draw
(scx_lavd intel_pstate active > intel pstate active > EAS intel pstate
passive), but there are some odd performance results, where only E-cores are used for
single-threaded workloads like "zstd -b1" and "pv /dev/urandom >
/dev/null". From my initial testing it seems to be way more convervative
with using P-cores for these specific workloads, and only uses them if
most of E-cores get overloaded, unlike EAS that engages P-cores when one
E-core is utilized above 80%.
