From 2c7224e488457afb7bb76664c4b7c857baef1e08 Mon Sep 17 00:00:00 2001 From: Chris Wilson Date: Tue, 14 Aug 2018 14:03:52 +0100 Subject: lib: Keep upto half of RAM reserved for test runner Halve our estimated available RAM for use by the tests to avoid nasty situations where the test runner may force us into swap. Rumour has it that the new runner isn't quite so bloated as piglit...
