From da6198afb01df0dce47fde23b53183cc0009b6a2 Mon Sep 17 00:00:00 2001 From: Matthew Auld Date: Tue, 20 Dec 2022 11:27:36 +0000 Subject: [PATCH] drm/i915/ttm: remove the virtualized start hack This was mostly needed to differentiate between mappable and non-mappable lmem, such that ttm would understand non-mappable -> mappable moves (or vice versa), and not just turn them into noops. We have since gained proper .intersects() and .compatible() hooks for the resource manager, which takes care of this for us.
