Earlier this year, the Raspberry Pi Foundation hooked up with Igalia to start development on an open-sourced Vulkan graphics driver for the Raspberry Pi. However, Martin Thomas, an engineer at Nvidia, beat them.
Thomas announced yesterday via his personal Twitter that his RPi-VK-Driver is ready for primetime. The engineer had been working on the Vulkan driver in his spare time for more than two years.
Technically, Thomas' iteration isn't a Vulkan driver per se because it doesn't comply with the official standards established by The Khronos Group.
The developer produced a driver that follows the Vulkan parameters as much as possible, and as close as the hardware would permit it. There's just one limitation with the RPi-VK-Driver though. Unlike the official Vulkan driver that's still in the works, Thomas' version is only compatible with the Broadcom VideoCore IV GPU that's found inside the Raspberry Pi 1, 2, 3, and Zero devices.
