Phoronix: V3DV Developers Lay Out Plans For Upstreaming The Raspberry Pi 4 Vulkan Driver In Mesa

Building off the V3DV driver talk at XDC2020 about this open-source Vulkan driver for the Raspberry Pi 4 driver, the Igalia developers responsible for this creation have laid out their plans on getting this driver upstream within Mesa...

Why are some drivers developed from scratch inside Mesa and others are merged once they're complete?

Interested, in due course, in seeing the the performance of these drivers (obviously first working drivers will put reliability above performance, and have optimisations in the future) compared to OpenGL on the same games, where possible.

Up to the developers working on the code.

which vulkan driver was developend from scratch inside mesa?

it's not possible to compare different apis on same game. even if game supports two apis, it's really two games and one can be better written than other. i.e. you can compare, but you can't compare drivers in isolation

i guess "from scratch inside mesa" is open for interpretation

I mean, when it was first merged, I think some simple spinning triangle demo worked, and that was about it. So yeah, basically all the development happened upstream.
