From 0088e522ddcb2cb5763ad85f9db2c2b473843d8d Mon Sep 17 00:00:00 2001 From: Chris Wilson Date: Thu, 4 Aug 2016 07:52:21 +0100 Subject: drm/i915: Split GGTT initialisation between probing and setup In order to handle conflicting drivers (i.e. vgacon) having a different setup of hardware, we have to remove those other drivers before we try to setup our own mappings. This requires us to split GGTT initialisation between probing for the hardware location (part of the PCI BAR) and later establishing the kernel resources for it.
