AMD --
For those concerned about the Reverse PRIME and multi-screen Reverse Optimus enablement for the AMD open-source X.Org driver, the support is now present in its Git tree.

After the Nouveau driver last month gained multi-screen Reverse Optimus support, AMD's Alex Deucher ported it to the AMD driver. After going through code review, this code has been committed to the xf86-video-ati Git tree.

This multi-screen Reverse Optimus is for configurations where the dedicated GPU -- on hybrid laptops with a combination of an integrated Intel GPU and a discrete AMD GPU -- is driving multiple displays and being powered by the integrated GPU. This support takes advantage of a newly-exposed X.Org Server interface. For more details on the functionality, see the related forum thread.

The specific commits worth pointing out tonight are radeon: add support for reverse prime (v2) and drmmode: add support for multi-screen reverse optimus.
