PowerVR ======= PowerVR is a Vulkan driver for Imagination Technologies PowerVR GPUs, starting with those based on the Rogue architecture. The driver is conformant to Vulkan 1.0 on `BXS-4-64 `__, but **not yet on other GPUs and Vulkan versions**, 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 ========= =========== ============== ======= AXE-1-16M A-Series 33.15.11.3 1.2 BXS-4-64 B-Series 36.53.104.796 1.2 BXM-4-64 B-Series 36.52.104.182 1.2 BXM-4-64 B-Series 36.56.104.183 1.2 ========= =========== ============== ======= The following hardware is partially supported and not currently under active development: ========= =========== ============== ======= ========== Product Series B.V.N.C Vulkan Notes ========= =========== ============== ======= ========== GX6250 Series 6XT 4.40.2.51 1.2 [#GX6250]_ ========= =========== ============== ======= ========== .. [#GX6250] Various core-specific texture, compute, and other workarounds are currently unimplemented for this device. Some very simple Vulkan applications may run unhindered, but instability and corruption are to be expected until the aforementioned workarounds are in place.

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.
