Help With AMDGPU

Post by ptstart »

Hey, I have the AMDGPU drivers and just compiled from source. I've noticed that this engine seems to require OpenGL 4.1 but the compatibility profile only supports upto 3.0 with these mesa drivers, which is the default? Otherwise the 'base game' shows nothing other than the background image I think.

If I do ForceCoreContext = 1 in springsettings.cfg I now get lots of 'missing extensions', I assume deprecated and thus missing from the core profile. Since I'm on Ubuntu 18.04 so I don't think AMDGPU-PRO is an option for me. As you might expect ignoring the missing extension errors gives something like this:

Does anyone know how I can get this engine running with amdgpu drivers? thank you and sorry in advance if i got anything wrong or if this is the wrong board. I just want to get spring working for me :)

EDIT: oh and I also used 'export MESA_GL_VERSION_OVERRIDE=4.5'

last time i tried the development branch i got the same on windows / with amd gpu, too.

i've created an issue as this question about the current state comes up often: https://springrts.com/mantis/view.php?id=5971

only kloot can answer the question about the state of the migration / whats left IMHO.

in short: gfx code is currently ported to opengl 4.5 core profile but its not done yet.

the "maintenance" branch contains most changes of the devlopment branch excluding the opengl changes.

Compile the maintenance branch (also required for multiplayer sync), not develop.

Here's a small list of deprecated stuff still left in that produces OpenGL debug warnings in the menu, if at all useful:

GlobalRendering.cpp:
1079 glTexEnvf(GL_TEXTURE_FILTER_CONTROL, GL_TEXTURE_LOD_BIAS, lodBias * (absBias > 0.01f));

CFontTexture.cpp:
667 glPushAttrib(GL_TEXTURE_BIT);
681 glTexImage2D(GL_TEXTURE_2D, 0, GL_ALPHA, 1, 1, 0, GL_ALPHA, GL_UNSIGNED_BYTE, nullptr);
682 glPopAttrib();

MatrixState.cpp:
80 void GL::MatrixMode(unsigned int glMode) { glMatrixMode(glMode); }
181 void GL::LoadMatrix(const CMatrix44f& m) { glLoadMatrixf(m); }

that's all I can find right now.

Update: I almost got a bit of the UI working if anyone's at all interested.

This is with the OpenGL 4.5 'core' profile. There were some small changes to do with font rendering etc. Is this useful or am I wasting time?

The fork is here if you're interested:
https://github.com/pts1667/spring

I'm quite new to github... do I just make the pull request now? I don't think I broke anything (hopefully), but I can't test on a system with 4.5 compat profile so I'm not sure if I broke anything.

yes! the pull request automatically updates when you add commits to the branch where the pull request was created from.

i'm noob wrt opengl, so i can't say much to the changes. very likely kloot / hokomoko / jk will review / comment the changes.

OK, I sent the PR request. Although with the latest state on the repo there appears to be crashes on startup with sound? So I can't see if I messed something up with git...

can you paste the stacktrace wrt the crash and infolog.txt?

i've tested current development branch with your changes and it doesn't crash for me...

Is this it? Again not 100% sure if it has to do with sound, just guessing. This is the debug build.

wrt the SIGFPE:

in debug builds DEBUG_SIGNAL_NANS is automaticly enabled: https://github.com/spring/spring/blob/d ... s.txt#L342

it is used to fix desync errors. as this SIGFPE happens in an external lib very likely it can be ignored / is maybe not fixable in spring.

so, either try to disable Sound or disable DEBUG_SIGNAL_NANS.
