From 34a04e5e46cb984a6bab336484fa856574db332f Mon Sep 17 00:00:00 2001 From: Chris Wilson Date: Wed, 13 Sep 2017 09:56:03 +0100 Subject: [PATCH] drm/i915: Allow HW status page to be bound high MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit At the time of commit 1f767e02d69f ("drm/i915: HWS must be in the mappable region for g33"), drm_mm insertion would often default to placing a new object high in the zone forcing us to specify that certain HWSP must be bound within the low mappable region. Since then, drm_mm has gained more finesse over its placement and exposes that to the caller, commit 4e64e5539d15 ("drm: Improve drm_mm search (and fix topdown allocation) with rbtrees"). As such where possible we want the HWSP to be outside of the mappable aperture and so need to specify that can be pinned high.
