Subject: [DO NOT REVIEW 04/11] drm/xe/display: Use the correct calculation for phys_base on integrated
Date: Mon, 20 Jul 2026 18:14:56 +0200 [thread overview]
Message-ID: <20260720161451.384968-17-dev@lankhorst.se> (raw)
In-Reply-To: <20260720161451.384968-13-dev@lankhorst.se>
The code originally assumed there was a 1:1 mapping between
stolen and GGTT offset. This is no longer true as of MTL, so
perform the correct calculations, similar to how they're
performed for the DGFX case.
