PowerVR — The Mesa 3D Graphics Library latest documentation

# 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.

## Hardware glossary

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.
