From b50b821eb35bc783f463b80e4a284d55caaf0e37 Mon Sep 17 00:00:00 2001 From: Jason Ekstrand Date: Tue, 16 May 2017 14:58:00 -0700 Subject: [PATCH] i965/blorp: Properly handle mt->first_level The guts of blorp and ISL don't understand i965's partial miptrees. Instead, we need to subtract off first_level before we hand anything off to blorp.
