Subject: [PATCH AUTOSEL 4.14 10/16] cpufreq: intel_pstate: Only mention the BIOS disabling turbo mode once
Date: Thu, 7 May 2020 10:29:37 -0400 [thread overview]
Message-ID: <20200507142943.26848-10-sashal@kernel.org> (raw)
In-Reply-To: <20200507142943.26848-1-sashal@kernel.org>
From: Chris Wilson <chris@chris-wilson.co.uk>
[ Upstream commit 8c539776ac83c0857395e1ccc9c6b516521a2d32 ]
Make a note of the first time we discover the turbo mode has been
disabled by the BIOS, as otherwise we complain every time we try to
update the mode.
