RockPro64 4GB

Those lovely people at Pine, have sent me a new toy Big Grin

Another RK3399 board but also a bit of a big beast with lots of ports and extra bits on it, they've been kind enough to supply the heatsink and power supply too.

Sadly though need to wait till the weekend (or next) to play with it, but I'll download whatever OS they have and see what it can do when I've got some spare time

Just firing it up with Ubuntu, it needs a few things installed, but it does run the maze demo, but it does not look like there are any drivers, mesa is emulating and the demo runs at 24fps on a half size screen

hmm

Armbian also has no GPU drivers.

so its best for now to work with Ubuntu and hopefully some drivers will come along soon

oh wait...going back to Ubuntu, and trying glmark2-es2 it might actually be doing a bit more than emulating...I'll try to avoid installing mesa and see if it can handle the demo better

hmm can't get it to work without mesa, there is a GL folder in place, so maybe it can handle full fat GL better than GLES2.0
Installing the Mesa libs does get it all working, but at half speed on the maze demo, suggesting a lot of emulation, though it is reporting it as a proper Mali 860 with an apparent tonne of good extensions and glmark2 offscreen still gives a reasonable score of around 200 before and after mesa libs installed. Not sure what to make of it.

I'll have to get back to it another time, for now its not as immediately usable as the RockPi4 so hopefully some updates soon will fix that.

I tried ubuntu again but kept getting some odd errors and it would only set up if I disabled mipmapping, which is very odd... So decided to try Debian which seems to have on board drivers.

And yes, aside from being a bit slow when 1st booted up, (which is not actually unusual as it sets things up in the background), performance improved after an update/upgrade cycle, I only needed to install GLM/STB and GDB to get things up and running.

The Maze demo compiles, nice and fast and runs, though not at the steady 60hz I was hoping for, but close enough. restoring mipmapping boosted speed a bit but it did still drop down from 60 which I wouldn't expect from such a powerful GPU. The only problem is the MD2 textures and overall render of the maze demo is rather dark..not sure why. Probably a simple issue with ambiant light values in the shader that need adjusting rather than using fixed numbers.

Its using mesa libs, since an attempt to install them said they were already there, but it is working much better than the Ubuntu version which seemed to emulate more and slowed down on even a half sized screen.
So I'll stick to this version of Debian for now, its being actively supported (so is unbuntu in fairness)

Ain't Linux fun?

What is interesting with your findings is that Ubuntu is based on Debian, so it's more than likely a version issue.

On Ubuntu, if you cat /etc/debian_version you can see what version it is based on.

well they are all based on some old core Linus wrote Big Grin

I really don't enjoy Linux, the variation and lack of consistancy even from machine to machine is deeply frustrating.. I can't imagine trying to actually produce a commercial quality project on Linux, imagine the number of builds and versions you need to take care of...shudder.
