* drm/i915: Explosion following OOM in do_execbuffer.Chris Wilson2010-08-021-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Oops, when merging the extra details following an OOM, I missed that driver_private is now NULL and the correct way to convert from the drm_gem_object into the drm_i915_gem_object is to use to_intel_bo().

* gpu/drm/i915: Add a blacklist to omit modeset on LID openThomas Bächler2010-08-021-0/+23
| | | | | | | | | | | | On some machines (currently only the Toshiba Tecra A11 is known), the GPU locks up when modeset is forced on LID open. This patch adds a new DMI blacklist and omits modesetting for all matches.

| | | | | | | | | | | | | | | | | | | | | | | | BIOS scripts usually make an attempt to reset the AGP controller, however on some nv4x cards doing it properly involves switching FW off and on: if we do that without updating the AGP bridge settings accordingly (e.g. with the corresponding calls to agp_enable()) we will be locking ourselves out of the card MMIO space.

| | | | | | | | | | | | | | | | | | | | | | On nv50 it became impossible to attempt a PCI ROM shadow of the VBIOS, which will break some setups. This patch also removes the different ordering of shadow methods for pre-nv50 chipsets. The reason for the different ordering was paranoia, but it should hopefully be OK to try shadowing PRAMIN first. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>

| | | | | | | | | | | | | | | | | | | | In some situations it's possible we can receive a spurious hotplug IRQ before we're ready to handle it, leading to an oops.
