PowerVR

PowerVR is a Vulkan driver for Imagination Technologies PowerVR GPUs, starting with those based on the Rogue architecture.

The driver is not yet fully conformant so it requires exporting PVR_I_WANT_A_BROKEN_VULKAN_DRIVER=1 to the environment before running any Vulkan content.

The following hardware is currently in active development:

Product	Series	B.V.N.C	Vulkan	Conformant
GX6250	Series 6XT	4.40.2.51	1.0	No
AXE-1-16M	A-Series	33.15.11.3	1.0	No
BXS-4-64	B-Series	36.53.104.796	1.0	No

In some cases, a product name is shared across multiple BVNCs so to check for support make sure the BVNC matches the one listed. As the feature set and hardware issues can vary between BVNCs, additional driver changes might be necessary even for devices sharing the same product name.

Hardware documentation can be found at: https://docs.imgtec.com/

Note: GPUs prior to Series6 do not have the hardware capabilities required to support Vulkan and therefore cannot be supported by this driver.

BVNC

Set of four numbers used to uniquely identify each GPU (Series6 onwards). This is used to determine the GPU feature set, along with any known hardware issues.
