Title: Linux mali graphics acceleration
Post by: Da_Blitz on March 14, 2018, 07:09:13 am

While going through my RSS feeds this landed in my lap

MALI Driver (https://notabug.org/cafe/chai)

the TL;DR is that someone is working on mali GPU drivers for linux

It would appears that there is ongoing work (Post-lima) to have OSS graphics drivers. this is for the T860 and not the T880 as is in the x25/X27 however the difference between these chips is mainly the amount of cores and should just be a simple a matter of testing and perhaps updating a constant or two

Based on the authors blog posts work seems to be happening at a quick pace and so i am hopeful there should be something usable in the coming months

cant wait till there is something i can run on my chromebooks and phone

What is Mali, and what will this driver do for the Gemini?

(Sorry to be ignorant, but if I don't know, I suspect some others might not know either.)

Nice! It would be great to have a working GPU driver when starting to work with Linux

Mali is a family of ARM GPUs, one of which is baked in to the Mediated X25/X27 system on chip.

Most important links to the open source driver effort:

They are also on #panfrost at freenode (irc).


We have a Mali T880 MP4 in it, which is Midgard 4th gen ( https://en.wikipedia.org/wiki/Mali_(GPU) (https://en.wikipedia.org/wiki/Mali_(GPU)) ).

Things are moving at an awesome pace!

So I haven't checked out the new driver yet but maybe, just maybe, we can stop using hwcomposer in the very near future...?
