From 5b34406f5484e5f2adf86e43c89aa5f778a9c200 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Christian=20K=C3=B6nig?= Date: Mon, 11 Nov 2019 13:44:40 +0100 Subject: [PATCH] drm/ttm: refine ghost BO resv criteria MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Ghost BOs need to stick with the resv object only when the origin is imported. This is a low hanging fruit to avoid OOM situations on evictions.
