I don't mean to detract from the technical merits of this at all, but for those not aware you might be interested to know that ImaginationTech is a Chinese-owned firm.
There are a lot of chips that are very poorly documented and supported by abysmal proprietary SDK. The software part of hardware is so often an afterthought yet it is also what makes or breaks the product.
And they're sort of known for historically being very anti open source and their SDK difficult to continuously integrate into a larger product.
