Mesa: glxgears crashes on 32bit ARM devices #10226

Closed Yisus7u7 closed 2 years ago

Yisus7u7 commented 3 years ago

Problem description

The window comes out for a few seconds and then disappears

Screenshot_20210726-122626

Info: Android 8.0 32 bits 2GB of ram DE: lxqt WM: Openbox Using vnc

In proot it works, but in termux anything related to OpenGL does not want to work

Steps to reproduce

Expected behavior

Yisus7u7 commented 3 years ago

ghost commented 3 years ago

VNC doesn't have GLX extension. So forget about everything that uses GLX at least until someone manages to get it working.

I've seen people in the reddit group who do it, and it works well for them.

ghost commented 3 years ago

They probably used XSDL.

Yisus7u7 commented 3 years ago

No, is vnc:

ghost commented 3 years ago

Here is an output of xdpyinfo:

There no GLX and I even has disabled it intentionally for tigervnc which uses same build options as xorg-xvfb-server.

ghost commented 3 years ago

What is on reddit is GLFW examples and not glxgears.

Yisus7u7 commented 3 years ago

The GLFW examples also happen to you

Yisus7u7 commented 3 years ago

even freeglut fails me

ghost commented 3 years ago

@Yisus7u7 I really have no idea whether freeglut works or not. These packages were added as requested and since then I didn't get any reports about whether they actually work or not.

Yisus7u7 commented 3 years ago

Oh ok :(

ghost commented 3 years ago

I just got glxgears working (sources). So it may rather depend on where you got it and how it was compiled, but not on GLX extension presence.

Yisus7u7 commented 3 years ago

Thanks

@Yisus7u7 maybe because you're on arm32

@xeffyr I tried the one in that repository and it doesn't work either.

mesa-demos does work on aarch ... it just doesn't work on 32bit arm cpu

I guess patches should be made for arm32

Then you have to see what the problem is and create patches.

If I was smart enough to do that I would've already done that 🥴 ...

someone did help me to native compile the mesa library and I think it worked probably ... but no way to test it ...

can you give me a test program to check wheather OpenGL works or not ?

btw ... i have those scripts on my GitHub repo ... just go to Termux-Faint-Hope repo and copy the patches folder in /sdcard/ and run the myScripts/build-zink.sh or myScripts/build-mesa.sh

I also had that mistake once I compiled mesa...

I think bookstores are broken.

termux/termux-packages#10226

Here is how I compiled glxgears (I intentionally mentioned only the .c file and not the whole repo):

~ $ curl -LO https://github.com/JoakimSoderberg/mesademos/raw/master/src/xdemos/glxgears.c
  % Total    % Received % Xferd  Average Speed   Time    Time     Time  Current

~ $ clang glxgears.c -o glxgears -lGL -lX11 -lm

Running it:

~ $ export DISPLAY=:1
~ $ ./glxgears 
7265 frames in 5.0 seconds = 1452.936 FPS

P.S. I don't use custom mesa with these experimentals with gallium, zink, adreno drivers and other attempts to enable hardware acceleration. Simply installed build-essential xorgproto libx11 mesa tigervnc.

@xeffyr just doesn't work on arm (32-bit)

Yisus7u7 commented 3 years ago

According to this comment

https://github.com/ptitSeb/gl4es/issues/342#issuecomment-931310418

Could it be that disabling glx and mesa-dri has to do with this?

ghost commented 3 years ago

@Yisus7u7 It works on AArch64, i686 and x86_64. So nothing to do with it. But note that gl4es is broken completely, see https://github.com/termux/x11-packages/issues/442 for details.

It's not just gl4es, glu, freeglut, glew and other openGL-related libraries not working

sukualam commented 3 years ago

I try glxgears on xwayland (use termux x11 app) and it crash too (Segmentation Fault)

I use 32 bit prefix termux bootstrap (my device actually 64 bit)

On 64 bit termux bootstrap (default) glxgears works fine in xwayland

Yisus7u7 commented 3 years ago

Then we can confirm that in arm (32-bit) OpenGL does not work

sukualam commented 3 years ago

Screenshot_20211007-161825_Termux_X11

btw, i just use Xephyr to make nested x server in xwayland, it somewhat bad performance, but it can software renderer and glxgears work in Termux X11 (i user 32 bit proot debian)

my command: (on termux) termux-x11 & (I login to proot debian 32 bit, then use this command) env DISPLAY=:0 Xephyr :1 -fullscreen & env DISPLAY=:1 xfce4-session

Then, run glxgears from that session...

Use termux from fdroid is fine, i also from fdroid too, its not problem... you need to install termux-x11.deb inside termux

@xeffyr Based on this, will OpenGL in arm not be able to access any driver or library?

ghost commented 3 years ago

@Yisus7u7 x11-packages never supported any kind of hw acceleration (officially) and therefore doesn't require any driver to work. In fact, mesa here is provided to fullfill dependency needs of gtk and qt5 libs and maybe for some other packages. I don't know how deeply OpenGL is broken but on my device glxgears works as was shown previously.

Yisus7u7 commented 3 years ago

Well, I don't know if glxgears use opengl, but it still fails in arm.

ghost commented 3 years ago

glxgears use exactly OpenGL (not OpenGLES) and yes, it still fails because not fixed.

sukualam commented 3 years ago

Well, I don't know if glxgears use opengl, but it still fails in arm.

Are you in proot? If yes, you can just run Xephyr on top of Termux Wayland (Termux X11) or Xserver-xsdl.... and you can run glxgears there and some 3D software rendering too.. but performance is very low fps

sukualam commented 3 years ago

Use termux from fdroid is fine, i also from fdroid too, its not problem... you need to install termux-x11.deb inside termux

why this error ?

Screenshot_2021-10-09-06-27-15-493_com termux

Download from github action, use the latest build https://github.com/termux/termux-x11/actions

sukualam commented 3 years ago

aftef you run xephyr :1, then just

env DISPLAY=:1 glxgears

Then view it in your termux X11 app

Btw, this is for proot distro, the xephyr unavailable in termux repo

You need to inside proot (proot-distro) for this method

truboxl commented 3 years ago

I try adding TERMUX_DEBUG_BUILD=true into https://github.com/termux/x11-packages/blob/master/packages/mesa/build.sh

Rebuild, install and use gdb to get these outputs I tested this on aarch64 but installing arm32 Termux app from https://github.com/termux/termux-app/actions and it's reproducible So pretty much confirm arm32 Mesa is broken
