From 9db20748fd1af930920424a95321ee11b6eae16e Mon Sep 17 00:00:00 2001 From: Ian Romanick Date: Thu, 14 Nov 2019 14:12:30 -0800 Subject: [PATCH] gallium: Add a cap bit for OpenCL-style extended integer functions Iris will eventually enable this. Looking at the header files, it looks like Midgard could also enable it. Basically, any GPU that fully supports OpenCL can. v2: Add default value to u_screen.c. Suggested by Caio.
