From: Hans Verkuil <hans.verkuil at cisco.com> Repost because I wasn't a member of the nouveau mailinglist the first time around and this series was blocked. I also updated this cover letter for the part about the amdgpu patch after receiving feedback from Alex Deucher. The patches are unchanged (except for adding Alex' Acked-by to the amdgpu patch).

Some notebook systems provide the EDID for the internal panel via the _DDC method in ACPI, instead of or in addition to providing the EDID via DDC on LVDS/eDP. Add a DRM helper to search for an ACP _DDC method under the ACPI namespace for each VGA/3D controller, and return the first EDID successfully retrieved via _DDC. Update the i915, nouveau, and radeon DRM-KMS drivers to fall back to

linux guest driver implementation of the VIRTIO_GPU_F_EDID feature.

From: Hans Verkuil <hans.verkuil at cisco.com> Now that the DisplayPort CEC-Tunneling-over-AUX drm+i915 support has been merged in the mainline kernel it is time to roll this out to nouveau and amdgpu as well. I combined both in the same patch series since both depend on the same first patch, the comments in this cover letter apply to both and the implementation is also very similar (and

THIS IS UNTESTED for anything other than i915. Use previously parsed EDID where possible for display audio/hdmi detection. This in turn reduces edid_blob_ptr usage in a number of places. Further reduce edid_blob_ptr usage, and document that it should not be used by drivers directly. BR, Jani. Cc: Alain Volmat <alain.volmat at foss.st.com> Cc: Alex Deucher <alexander.deucher at
