This patch-set adds few additional sysfs entries to expose the performance capabilities of each CPU. The performance capabilities include highest perf, lowest perf, nominal perf and lowest non-linear perf. See 8.4.7.1 for ACPI 6.1 spec for details on these capabilities. cppc_cpufreq driver operates in KHz scale whereas the delivered performance computed in userspace will be in abstract CPPC scale, so exposing perf capabilities should allow userspace to figure out the conversion factor from CPPC scale to KHz.
