Current state of video acceleration in mainline and arm -current
 
It seems most of us here deal with devices having Mali400 GPU or some of it's siblings.

And some of us actually use it for screen-fun, so could benefit of acceleration, be it 2D or better yet 3D

The way I understand it, the Allwinner come with some sort of "patched" kernel having binary blobs of some sort video codec of what ever.

Outside of that, the mainline is by ways of device tree, struggling to have lan, i2c, spi thermal and voltages as stable and usable as possible.

Sound is work in progress, while can be used, has a while to go yet.

The GPU on the other hand is left with "short sleeves".

Or am I wrong?

I would like to see success stories, code snippets and URLs here, kind please?

Hi,
Maybe you know about it, maybe you don't : http://limadriver.org/ is an OSS driver for Mali GPUs. I only know it exists, don't have how to try it.

@serafean
good pick, they certainly could use some exposure to their project?

Other than that, i'm not binary-blob shy, but I certainly would prefer an GPL/open source solution to the MALI GPUs

@others
anyone else?

I have the habit to steal the Android kernels (and modules) using whatever Voodoo methods, and reuse it on Linux.

IF I manage to find the Android kernel Source, I prefer to rebuild it with more modules, but always using that Android variant.

Combined with the MALI user-space binaries, yo can have a shiny desktop.

Whaat? only boasting and no HOWTO :rolleyes:
Surely @Darth Vader can do better than that?
;)
Especially if matching the Slackware kernel version?

Me personally, I don't like to run my Slackware on an 3.16 or whatever "backport" kernel.

Lima!
 
I only lately found this, but it sheds (some?) light to the lima (ma<->li?) driver and it's (mis?)fortune.

This dude certainly could use some helping hands (over keyboards that is) and some friendly (virtual at least) shoulder patting?

the blog of the open lima driver

good read up IMO.
:hattip:

4.20 series might cut it even :D

Stay tuned!

Hello


Xorg wants sun4i-drm_dri.so and it seems that we need Mali for it.

Has anybody made build scripts already?

SCerovec 02-19-2019 02:57 PM

I might actually get busy with it (again) :D
