From 33ff1f21bd2fb69620d5ffc7afccf74cbc403097 Mon Sep 17 00:00:00 2001 From: Michal Wajdeczko Date: Thu, 11 Jan 2024 19:25:59 +0100 Subject: drm/xe: Allow to exclude part of GGTT from allocations MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Soon we will be required to exclude some of the GGTT addresses from the allocations, since on some platforms running the SR-IOV VF mode, we will be able to use only selected range of the GGTT space. Add helper functions to manage such GGTT range exclusions, and follow the naming from the similar concept used by GVT-g.
