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 <https://www.khronos.org/conformance/adopters/conformant-products#submission_936>`__,
|
|
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:

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.

Device info and firmware_ have been made available for these devices, typically
|
|
due to community requests or interest, but no support is guaranteed beyond this.

|
|
|
|
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.
