From 349712018bb05d7709bb90af194c544cb9e3474d Mon Sep 17 00:00:00 2001 From: Lionel Landwerlin Date: Tue, 29 Aug 2017 10:41:27 +0100 Subject: [PATCH] i965: add a debug option to disable oa config loading This provides a good way to verify we haven't broken using the perf driver on older kernels (which don't have the oa config loading mechanism).
