From bfcd92a0ae2996a34b1fd020b3e0951946ae6903 Mon Sep 17 00:00:00 2001 From: Ilia Mirkin Date: Fri, 19 Jul 2013 06:27:45 -0400 Subject: [PATCH] drm/nouveau/core: xtensa firmware size needs to be 0x40000 no matter what The current logic is wrong since we send fw->size >> 8 to the card. Rounding the size up by 0x100 and 0x1000 didn't seem to help, the card still hung, so go back to what the blob does -- 0x40000.
