From f6afed7076a6ef446dbec7cb10c8f8c60efafccd Mon Sep 17 00:00:00 2001 From: Maarten Lankhorst Date: Wed, 10 Sep 2014 13:17:13 +0200 Subject: nouveau: re-allocate bo's on overflow The BSP bo might be too small to contain all of the bsp data, bump its size on overflow. Also bump inter_bo when this happens, it might be too small otherwise.
