From ea3331d1201fa04904d87698055b84fa29f23869 Mon Sep 17 00:00:00 2001 From: Eric Anholt Date: Mon, 25 Jan 2016 19:51:21 +0000 Subject: [PATCH] igt: Disable igt_clflush_range() implementation on ARM builds Daniel has suggested that I put vc4 testing into igt, since it's got the piglit integration and KMS coverage already. This gets the ccore building so that I can start writing tests.
