Subject: [PATCH v9 1/8] cpufreq: amd-pstate: Document *_limit_* fields in struct amd_cpudata
Date: Tue, 19 Mar 2024 16:28:36 +0800 [thread overview]
Message-ID: <4b00dae2cc2ed3146a747a7fc72438972c689dca.1710836407.git.perry.yuan@amd.com> (raw)
In-Reply-To: <cover.1710836407.git.perry.yuan@amd.com>
From: "Gautham R. Shenoy" <gautham.shenoy@amd.com>
The four fields of struct cpudata namely min_limit_perf,
max_limit_perf, min_limit_freq, max_limit_freq introduced in the
commit febab20caeba("cpufreq/amd-pstate: Fix scaling_min_freq and
scaling_max_freq update") are currently undocumented
Add comments describing these fields
Fixes: febab20caeba("cpufreq/amd-pstate: Fix scaling_min_freq and scaling_max_freq update")
