drm/amdgpu: just suspend the hw on pci shutdown

2016-12-07T16:17:21Z

We can't just reuse pci_remove as there may be userspace still doing things. Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=98638 Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=97980 Reviewed-by: Christian König Reported-and-tested-by: Mike Lothian Signed-off-by: Alex Deucher

drm/i915: drop the struct_mutex when wedged or trying to reset

2016-11-30T10:09:26Z

We grab the struct_mutex in intel_crtc_page_flip, but if we are wedged or a reset is in progress we bail early but never seem to actually release the lock.

drm/i915: Don't touch NULL sg on i915_gem_object_get_pages_gtt() error

2016-11-30T10:07:05Z

On the DMA mapping error path, sg may be NULL (it has already been marked as the last scatterlist entry), and we should avoid dereferencing it again.

drm/radeon: fix check for port PM availability

2016-11-29T14:24:13Z

The ATPX method does not always exist on the dGPU, it may be located at the iGPU. The parent device of the iGPU is the root port for which bridge_d3 is false. This accidentally enables the legacy PM method which conflicts with port PM and prevented the dGPU from powering on.
