From 6dab04d7e3af2e0be8a05ca2df8c5669a5f54937 Mon Sep 17 00:00:00 2001 From: Kenneth Graunke Date: Mon, 3 Nov 2014 17:01:53 -0800 Subject: [PATCH] i965: Advertise larger line widths. MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit We've artificially been limiting this to 5 for no particular reason. On Gen4-5, the limit is [0, 7.5] with a granularity of 0.5 (U3.1). On Gen6+, the limit is [0, 7.9921875]. Since it's a U3.7, the granularity should be 0.125 (1/8). This patch conservatively advertises one granularity smaller than the hardware's maximum value, just in case there's a problem using the largest possible value. On Gen4-5, this is 7.5 - 0.5 = 7.0. On Gen6+, this is 8.0 - 0.125 = 7.875.
