From a7eb12d089e1a7f8a311c46aa6aed5dccdeb04ec Mon Sep 17 00:00:00 2001 From: Rob Clark Date: Mon, 11 Apr 2016 17:46:08 -0400 Subject: [PATCH] freedreno: fix max-line-width dEQP noticed that we were advertising completely bogus values. The actual maximum is 127.0f. *But* we have to use an artifically low maximum to work around a bug in the dEQP test, which gets confused when the max line width is too large and lines start going off-screen.
