From 57adc4cef617d7284ac7676e14533268e73e3699 Mon Sep 17 00:00:00 2001 From: =?utf8?q?Christian=20K=C3=B6nig?= Date: Thu, 1 Mar 2018 11:01:52 +0100 Subject: [PATCH] drm/amdgpu: change amdgpu_ttm_set_active_vram_size MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit Instead of setting the active VRAM size directly provide a the info if we can use the buffer functions or not.
