From d7be322410887b94fe1ddc37a6ae63ea20721467 Mon Sep 17 00:00:00 2001 From: Rob Clark Date: Wed, 11 Sep 2013 10:06:29 -0400 Subject: [PATCH] freedreno/a3xx: fix VFD_INDEX_MAX overflow max_index may be 0xffffffff. The hardware does not need 1 + max_index (although it does not hurt unless max_index wraps around to zero).
