Well well, open source continues to grow, good! Imagination Technologies will be joining up with all the rest involved in Mesa development, with their PowerVR GPUs. Developer Frank Binns put up a Merge Request for Mesa that was announced here on a mailing list.
I'm excited to share that over the last year we've been working on a new Vulkan driver, compiler and Linux kernel DRM driver for our PowerVR GPUs. As it was important for us to do things "right", we got Collabora involved early on in the project. They've been a big help and have guided us with the approach and overall design of the driver.
Nice to see more companies look to the fantastic developers as open source consulting firm Collabora, who have done a huge amount of great work across many areas for Linux.
Their initial focus is on their Rogue architecture, which they said has already been tested using the Acer Chromebook R13. Curiously, they've only started with the Vulkan side and mentioned efforts to run OpenGL over Vulkan like Zink / ANGLE "We therefore felt that a Vulkan driver together with Zink/ANGLE would be a good way to support multiple APIs from the get go" — so maybe this will be one of the first drivers that perhaps won't do a full OpenGL driver and just let it be handled by something like Zink.
Hopefully over time we'll see more vendors go the open source route. This is the way.
