Open hexdump0815 opened 1 year ago

hexdump0815 commented 1 year ago

i just came across https://www.reddit.com/r/RISCV/comments/11u0a6y/using_box64_gl4es_i_launched_a_pc_game_on_my/ ... do you have written down the steps to make gl4es to work on the vf2 somewhere? i gave it a try a few weeks ago in LIBGL_FB=3 mode trying to get opengl working this way but failed (i think early on with dri auth errors or something similar) also i'm not 100% sure if my gpu setup is working properly. some notes about how you got it working (vf2 gpu side and gl4es side) would be very welcome.

a lot of thanks in advance and best wishes - hexdump

I just built with default option, in ~/git/gl4es then used is simply with LD_LIBRARY_PATH=~/git/gl4es/lib:$LD_LIBRARY_PATH glxgears for example. No specific LIBGL_FB option needed.

@ptitSeb - thanks a lot for the quick response - will give it a try this way soon

As a followup: https://www.reddit.com/r/RISCV/comments/11vtqkf/video_of_superhexagon_running_on_visonfive2_riscv/ here is gl4es in action on the Vision Five 2 :)

Also note that the SDL2 version built on the default Debian image is build only with GLES2 support, so if you need to use OpenGL, you need to build a custom SDL2 and not use the system one (still using LD_LIBRARY_PATH to override the libs).

i just gave it a try again and i got a bit further ... i think that i have manually setup the gpu stuff properly on my own image (https://github.com/hexdump0815/imagebuilder/releases/tag/230321-02) as the included egl tests seem to work ... glxgears are working as well with gl4es but glmark2 crashes (debug trace below) but it works if i set LIBGL_FB=3 although very slow. do you have any idea what might be wrong? is glmark2 working for you with gl4es?

ps: maybe my setup is still not fully ok and the tests just run against get mesa sw renderer? pps: just found this: "failed to open starfive: /usr/lib/dri/starfive_dri.so: cannot open shared object file: No such file or directory" - so maybe something is maybe still wrong?

glmark2 debug trace with gl4es, but without LIBGL_FB=3:

I don't understand. I have a Vision Five 2, and gles4 is working fine on the default debian image. Not parameter tinkering needed. I use LD_LIBRARY_PATH=~/git/gl4es/lib:$LD_LIBRARY_PATH glxgears and it just works.

hexdump0815 commented 1 year ago

it looks the problem is in the pvr gpu setup in my own image - will have to recheck that ... i guess as soon as i have sorted that out it should work if it works for you on the starfive image

hexdump0815 commented 1 year ago

i just confirmed that it is working fine on the original starfive debian image, so it is really a problem of my setup - sorry for the confusion

hexdump0815 commented 1 year ago

just as a little update: i have it somehow working now on my debian image using the starfive pvr, mesa and xorg binaries ... i was struggling quite a bit why glxgears were working, but glmark2 always failed on my image with "Failed to find suitable GLX FB config" but it worked on the starfive image ... after a lot of debugging i realized that the reson are the different glmark2 versions: 2021.12 in the starfive image and 2023.01 in my debian sid image were the problem - it looks like the newer glmark2 has problems with getting the best fb config ... the 2023.01 version actually works if i explicitely provide the visual config on the cmdline via: "glmark2 --visual-config buf=16:r=8:g=8:b=8:a=8:depth=24:stencil=8" ... glmark2-es2 has the same problem, so i think it is not related to gl4es, which is working quite well so far ...
