Imagination Already Has A Vulkan Driver In The Works For PowerVR GPUs

HARDWARE --
While hearing "PowerVR" tend to make Linux users cringe over memories of past Linux driver issues with Imagination's binary blobs, Imagination is among the vendors now experimenting with the new Vulkan graphics API and SPIR-V IR. Imagination too has already put out one of the first demos using this new graphics API.

Ashley Smith of Imagination wrote a very interesting blog post talking about the company's experimental GPU drivers for Vulkan on PowerVR graphics hardware and porting one of their OpenGL ES 3.0 tech demos to the Vulkan interfaces. In this process they found the Vulkan experience to utilize less CPU work, yields a leaner and more explicit graphics driver, more consistent performance, render commands can be parallelized, tile-based architectures can be very efficient with Vulkan, it's a more intuitive design, explicit memory management, and offers other benefits too.


As said in the earlier article, Vulkan on the hardware side should work with any OpenGL ES 3.1 graphics processors. Imagination Technologies is planning to release their demo Vulkan source code in the future. While already covered in the earlier article, don't expect any preview drivers ready for public consumption until later in the year, but then again there could be surprises -- especially with Valve expected to potentially demo some titles like CS:GO on Vulkan.
