Subject: [PATCH AUTOSEL 5.11 25/35] amdgpu/pm: Prevent force of DCEFCLK on NAVI10 and SIENNA_CICHLID
Date: Wed, 12 May 2021 14:01:55 -0400	[thread overview]
Message-ID: <20210512180206.664536-25-sashal@kernel.org> (raw)
In-Reply-To: <20210512180206.664536-1-sashal@kernel.org>

From: Darren Powell <darren.powell@amd.com>

[ Upstream commit b117b3964f38a988cb79825950dbd607c02237f3 ]

Writing to dcefclk causes the gpu to become unresponsive, and requires a reboot.
Patch ignores a .force_clk_levels(SMU_DCEFCLK) call and issues an
info message.
