=======

|
|
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:

GX6250 Series 6XT 4.40.2.51 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.
|
|
|
|

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