From e376573f7267390f4e1bdc552564b6fb913bce76 Mon Sep 17 00:00:00 2001 From: =?utf8?q?Michel=20D=C3=A4nzer?= Date: Thu, 8 Jul 2010 12:43:28 +1000 Subject: [PATCH] drm/radeon: fall back to GTT if bo creation/validation in VRAM fails. MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit This fixes a problem where on low VRAM cards we'd run out of space for validation.
