Overview
Power VR is a line of GPU by Imagination Technologies. It has zero Free Software/Open Source support right now, and the associated development effort seems to be regarded as very high. Imagination has hinted they were considering addressssing the problem[1] but today the position seem to be still open[2]
It is regarded as more powerful than the Mali400 GPU found in other SoCs (needs ref).
A Free Software driver for Power VR is considered as a high priority project by the FSF[3] and a project has indeed been setup[4].
Imagination Technologies published a linux driver for their binary microkernel under a dual license: MIT & GPL v2. [5]

| A83T | SGX544MP1 | 1.1.5 |
| A80 | G6230 | ? |
