From b7eea2d7e67cd4b65f42c00624277dae780f7009 Mon Sep 17 00:00:00 2001 From: Ilia Mirkin Date: Mon, 29 Jun 2015 20:49:48 -0400 Subject: [PATCH] drm/nouveau/fbcon/g80: reduce PUSH_SPACE alloc, fire ring on accel init Only 58 words get written to the ring, not 59. Also, normalize the accel init wrt nvc0 and nv04 fbcon impls by firing the ring at accel init time rather than waiting until "later".
