Subject: [PATCH v2 4/6] cpufreq: intel_pstate: Consolidate frequency values computation
Date: Fri, 19 Jun 2026 19:42:24 +0200	[thread overview]
Message-ID: <3425962.44csPzL39Z@rafael.j.wysocki> (raw)
In-Reply-To: <6005456.DvuYhMxLoT@rafael.j.wysocki>

From: Rafael J. Wysocki <rafael.j.wysocki@intel.com>

Update intel_pstate_get_cpu_pstates() to use
intel_pstate_update_freq_limits() for computing the max and
turbo frequency values in all cases, including non-hybrid HWP
and HWP disabled.

No intentional functional impact.
