1PowerVR 2======= 3 4PowerVR is a Vulkan driver for Imagination Technologies PowerVR GPUs, starting 5with those based on the Rogue architecture. 6 7The driver is **not yet fully conformant** so it requires exporting 8``PVR_I_WANT_A_BROKEN_VULKAN_DRIVER=1`` to the environment before running any 9Vulkan content. 10 11The following hardware is currently in active development: 12 13========= =========== ============== ======= ========== 14Product Series B.V.N.C Vulkan Conformant 15========= =========== ============== ======= ========== 16GX6250 Series 6XT 4.40.2.51 1.0 No 17AXE-1-16M A-Series 33.15.11.3 1.0 No 18BXS-4-64 B-Series 36.53.104.796 1.0 No 19========= =========== ============== ======= ========== 20 21In some cases, a product name is shared across multiple BVNCs so to check for 22support make sure the BVNC matches the one listed. As the feature set and 23hardware issues can vary between BVNCs, additional driver changes might be 24necessary even for devices sharing the same product name. 25 26Hardware documentation can be found at: https://docs.imgtec.com/ 27 28Note: GPUs prior to Series6 do not have the hardware capabilities required to 29support Vulkan and therefore cannot be supported by this driver. 30 31Chat 32---- 33 34PowerVR developers and users hang out on IRC at ``#powervr`` on OFTC.
