From 5b9cb1329557cc17e1533aed7c63e1252658d74b Mon Sep 17 00:00:00 2001 From: Emil Velikov Date: Thu, 14 Aug 2014 20:11:32 +0100 Subject: gallium/i915: handle query_renderer caps Implementation based on the classic driver with the following changes: - Use auxiliarry function os_get_total_physical_memory to get the total amount of memory. - Move the libdrm_intel specific get_aperture_size to the winsys.
