Hi All,

We need your help. All applications and desktops which use opengles and opengles2 have wrong colors. (pink or blue color)

Luigi has created a bug report on freedesktop.org. Please run the the following demo in your Firefox web browser and if you have the same problem, please report it.

Link to the demo: https://playcanv.as/p/SA7hVBLt/

Link to the bug report: Bug 99638

I have the same problem. I added my system to Luigi's bug report today.

Thanks in advance,
Christian

We are looking for someone who has a SI Radeon installed and can debug Xorg. We want to solve the problem with the 3D hardware acceleration with Radeon SI graphics cards (Radeon HD7xxx and higher). Please help us.

Michael Danze form Amd ask me to made some actions but im not able to debug the xorg.

I was able to compile Mesa with DRI3 support today.

First, I had to upgrade libdrm2.

Code: Select all
apt-get install -t experimental libdrm2


# dpkg -l libdrm2

Code: Select all
||/ Name                              Version               Architecture          Description

Download of the latest Mesa Git version:

Code: Select all
git clone git://anongit.freedesktop.org/mesa/mesa mesa-test


Configure Mesa with DRI3 support:

Code: Select all
./autogen.sh --prefix /usr/local/mesa-test --with-gallium-drivers="r600,swrast" --enable-texture-float --enable-dri3


Code: Select all

Code: Select all
# cp /usr/local/mesa-test/lib/libGL.so.1.2.0 /usr/lib/powerpc-linux-gnu/mesa/


I enabled DRI3 with Option "DRI3" "1" in the xorg.conf on the MATE PowerPC Remix 2017.

DRI3 works:

Code: Select all

6218 frames in 5.0 seconds = 1243.513 FPS
6229 frames in 5.0 seconds = 1245.722 FPS


Conclusion: DRI3 is faster than DRI2.

FYI:

Alex Perez via Facebook wrote:SI GFX is likely to never be supported by libMesa on Big Endian. Even if funds could be raised to pay someone competent to actually do the work, it's estimated at "hundreds of man-hours" by someone competent, who has previously contributed to Mesa, with specific knowledge and familiarity of Radeon and Big Endian hardware.

Hi All,

If you install the latest libgl1-mesa-glx_17.2.1-1_powerpc.deb on Debian Sid you will notice that the hardware 3D acceleration doesn't work. The problem is, the files libGL.so.1 and libGL.so.1.2.0 are missing in the package libgl1-mesa-glx.

Christian
