From 30db6471fc9878abdaf1bd88d4afffd1eb116dcd Mon Sep 17 00:00:00 2001 From: Daniel Vetter Date: Tue, 5 Sep 2017 18:45:42 +0200 Subject: demos: remove The igt testcase themselves contain plenty of demos, libdrm also contains a bunch of demos, this here just bitrots. So let's remove it. v2: Rebase. v3: Also delete demos/Makefile from configure.ac. This broke clean builds starting with autogen.sh.
