Subject: [PATCH 24/31] drm/amd/display: Move wm and dlg calculation to FPU code
Date: Fri, 15 Jul 2022 14:16:58 -0400 [thread overview]
Message-ID: <20220715181705.1030401-25-Rodrigo.Siqueira@amd.com> (raw)
In-Reply-To: <20220715181705.1030401-1-Rodrigo.Siqueira@amd.com>
Move dcn32_calculate_wm_and_dlg from dcn32 resources to the FPU code.
Additionally, this commit adds an interface to it.
