Subject: [PATCH AUTOSEL 4.14 18/25] drm/amdgpu: Update power state at the end of smu hw_init.
Date: Thu, 20 Sep 2018 02:48:28 +0000	[thread overview]
Message-ID: <20180920024810.58594-18-alexander.levin@microsoft.com> (raw)
In-Reply-To: <20180920024810.58594-1-alexander.levin@microsoft.com>

From: Rex Zhu <Rex.Zhu@amd.com>

[ Upstream commit 2ab4d0e74256fc49b7b270f63c1d1e47c2455abc ]

For SI/Kv, the power state is managed by function
amdgpu_pm_compute_clocks.

when dpm enabled, we should call amdgpu_pm_compute_clocks
to update current power state instand of set boot state.

this change can fix the oops when kfd driver was enabled on Kv.
