Subject: [Intel-gfx] [PATCH v2 39/50] drm/i915/adl_p: Enable/disable loadgen sharing
Date: Thu, 25 Mar 2021 11:07:09 -0700 [thread overview]
Message-ID: <20210325180720.401410-40-matthew.d.roper@intel.com> (raw)
In-Reply-To: <20210325180720.401410-1-matthew.d.roper@intel.com>
From: Mika Kahola <mika.kahola@intel.com>
Disable loadgen sharing for DP link rate 1.62 GHz and HDMI 5.94 GHz.
For all other modes, we can enable loadgen sharing feature.
