From 1f4bca798dda155ad0615ba81d8373c771d1ec94 Mon Sep 17 00:00:00 2001 From: Ilia Mirkin Date: Sat, 18 Jun 2016 21:54:37 -0400 Subject: [PATCH] nv50,nvc0: fix start_instance in manual push path The start instance is applied as an offset into the buffer directly, ignoring the divisor, not as an instance id offset that respects the divisor.
