Subject: [PATCH AUTOSEL 6.0 10/18] cpufreq: intel_pstate: Add Tigerlake support in no-HWP mode
Date: Sun, 9 Oct 2022 16:51:27 -0400 [thread overview]
Message-ID: <20221009205136.1201774-10-sashal@kernel.org> (raw)
In-Reply-To: <20221009205136.1201774-1-sashal@kernel.org>
From: Doug Smythies <dsmythies@telus.net>
[ Upstream commit 71bb5c82aaaea007167f3ba68d3a669c74d7d55d ]
Users may disable HWP in firmware, in which case intel_pstate wouldn't load
unless the CPU model is explicitly supported.
Add TIGERLAKE to the list of CPUs that can register intel_pstate while not
advertising the HWP capability. Without this change, an TIGERLAKE in no-HWP
mode could only use the acpi_cpufreq frequency scaling driver.
