| 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. |

| 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 |
