Subject: [PATCH 5/5] drm/radeon: Use TTM_PL_FLAG_BOTTOMUP
Date: Tue, 28 Oct 2014 18:35:06 +0900	[thread overview]
Message-ID: <1414488906-3924-5-git-send-email-michel@daenzer.net> (raw)
In-Reply-To: <1414488906-3924-1-git-send-email-michel@daenzer.net>

From: Michel Dänzer <michel.daenzer@amd.com>

We want to allocate small BOs strictly from the bottom up, just as large
BOs are allocated strictly from the top down.
