From 2a2e2f5f48278b9c4b96bb28997dd8e61932a0de Mon Sep 17 00:00:00 2001 From: =?utf8?q?Ville=20Syrj=C3=A4l=C3=A4?= Date: Fri, 15 Dec 2023 13:09:32 +0200 Subject: [PATCH] drm/i915/hdcp: Pin the hdcp gsc message high in ggtt MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit AFAICS there is no hardware restriction on where in ggtt the hdcp gsc message object needs to be bound. And as it's a regular shmem object we don't need it be in the mappabe range either. So pin it high to make avoid needlessly wasting the precious mappable range for it.
