When turbo is not disabled by BIOS, but user disabled from intel P-State sysfs and changes max/min using cpufreq sysfs, the resultant frequency is lower than what user requested. The reason for this, when the perf limits are calculated in set_policy() callback, they are with reference to max cpu frequency (turbo frequency ), but when enforced in the intel_pstate_get_min_max() they are with reference to max available performance as documented in the intel_pstate documentation (in this case max non turbo P-State). This needs similar change as done in intel_cpufreq_verify_policy() for passive mode. Set policy->cpuinfo.max_freq based on the turbo status.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
