I'd like to buy a board with that GPU (ODROID-XU3) and I want to be sure that I'll be able to use glNext on it. If not, then which GPUs are going to support it?
https://www.khronos.org/assets/uploads/developers/library/2015-gdc/Khronos-Vulkan-GDC_Mar15.pdf states that we have a prototype driver running on Arndale Octa (so T628 MP6), and I also dug up the following statement from our GDC FAQ:
ARM plans to support Vulkan broadly on capable current and future ARM Mali GPUs. Announcements will be made closer to release.
Hth,
Chris
