From 9f087e1c7cc869fcb9839282194560d289b7df59 Mon Sep 17 00:00:00 2001 From: Samuel Pitoiset Date: Wed, 25 Jan 2017 16:56:45 +0100 Subject: [PATCH] gallium/radeon: query the CPU accessible size of VRAM MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit R600_DEBUG="info" can be used to display that size, as well as the total amount of VRAM/GTT.
