Rpi4 support #4

Closed burt111 closed 5 years ago

burt111 commented 5 years ago

Just wondering if this would still work on the pi with videocore vi or is it incompatible

Yours3lf commented 5 years ago

I have no idea how the VC 6 works, it's probably completely different. My guess is no.

ghost commented 5 years ago

For what I hear its not much diferent than vc4... and its vulkan capable on the hardware. There is no more mesa development for now (not really active at least, just minor fixes).

ghost commented 5 years ago

Got some info on this: it does seem to be closer in spec to VC4 but adds features on top of VC5 so likely everything you have been missing, sounds like they did it "right" for what I can imagine would be good (not best) case senerio.

All the features needed for opengl es 3.2 and vulkan 1.1

Thought it might encourage you :-) Ref: https://www.raspberrypi.org/forums/viewtopic.php?p=1492907&sid=60a7c5feeb6c773f6db9e15b39049d2b#p1492907

Should we ever have a working Vulkan driver for VC6 in mesa, I think it would be easier to "migrate" necessary VC4 code to mesa. That said - I think we are still years away ;)

This is on pi4 ...

this driver only supports the Videocore IV GPU, so only RPi 0, 1, 2, 3 are supported. Give it a go there and let me know how that went.

darkdragon-001 commented 4 years ago

Official Raspberry Pi 4 Vulkan driver is in development by the consulting firm Igalia with a recent status update.

Previous MESA efforts for VC4 Vulkan support can be found in some vc4/v3d WIP branches by Eric Anholt.

See Phoronix for good media coverage (this is how I became aware of the project in the first place)!
