From 814f31457e9ae83d4f1e39236f704721b279b73d Mon Sep 17 00:00:00 2001 From: Marek Olšák Date: Tue, 20 Oct 2015 18:26:02 +0200 Subject: gallium: add PIPE_SHADER_CAP_MAX_UNROLL_ITERATIONS_HINT This avoids a serious r600g bug leading to a GPU hang. The chances this bug will get fixed are pretty low now. I deeply regret listening to others and not pushing this patch, leaving other users with a GPU-crashing driver. Yes, it should be fixed in the compiler and it's ugly, but users couldn't care less about that.
