It is NOT a complaint
Just curious to why 3D acceleration is not supported on Radeon SI graphics cards on PPC linux. And if there are any signs that this will happend down the road.
It has maybe been covered before and in this case sorry in advance!
Thank you in advance!

So in short it is caused by primarly this:
Glamor Crashes on big endian Hardware
https://bugs.freedesktop.org/show_bug.cgi?id=99859
The thread is from 2017 and no solution is in sight .... as far as I can read on a quick glance.
Ok. Thank you for the reply
. I am keeping my fingers crossed for a solution.
And thank you for all your work for PPC linux.

Hi All,
If you use a Radeon SI graphics card then please try the following xorg.conf:
/etc/X11/xorg.conf:
Code: Select all
Section "Device"
Option "UseFBDev" "true"
Identifier "Card0"
EndSection
Cheers,
Christian

I have tested with a fully updated Fienix and kernel 5.3. I am sorry to say that it does not work with a solo Radeon SI card.
Here is the xorg.conf before I rebooted:

Here is the result:

I can not get past the white screen.
I will try adding my Firepro to see if that helps.

It works here with a Radeon R7 240 and with the xorg.conf above.

I have a R9 270X 2GB installed in mine. Strange!
The R7 240 and the R9 270X should be the same architecture:
