Hi!
AFAICT, pstate file will contain something like
07: core 100 MHz memory 123 MHz * 08: core 100-200 MHz memory 123 MHz
...which does not look exactly like one-value-per-file, and I'm pretty sure userspace will get it wrong if it tries to parse it. Plus, I don't see required documentation in Documentation/ABI.
Should we disable it for now, so that userspace does not start depending on it and we'll not have to maintain it forever?
I guess better interface would be something like
pstate/07/core_clock_min core_clock_max memory_clock_min memory_clock_max
and then pstate/active containing just the number of active state?
Thanks, Pavel
