Subject: [PATCH v7 14/17] drm/amd/display: Add PBN per slot calculation for DSC
Date: Sat, 16 Nov 2019 17:01:25 -0500 [thread overview]
Message-ID: <20191116220128.16598-15-mikita.lipski@amd.com> (raw)
In-Reply-To: <20191116220128.16598-1-mikita.lipski-5C7GfCeVMHo@public.gmane.org>
From: Mikita Lipski <mikita.lipski@amd.com>
[why]
Need to calculate VCPI slots differently for DSC
to take in account current link rate, link count
and FEC.
[how]
Add helper to get pbn_div from dc_link
