I don't have reluctance. That was the guidance from x86 core
maintainers years back. But may have changed. So
Hi Srinivas,
I saw your V3.
I do not understand your reluctance to use
arch/x86/include/asm/msr-index.h
as the place to define anything MSR related.
Please explain.

By default intel_pstate driver disables energy efficiency by setting
MSR_IA32_POWER_CTL bit 19 for Kaby Lake desktop CPU model in HWP mode.
This CPU model is also shared by Coffee Lake desktop CPUs. This allows
these systems to reach maximum possible frequency. But this adds power
penalty, which
