Is it compatible with qemu? #391

Open dontknowhy opened 2 years ago

dontknowhy commented 2 years ago

Screenshot_20220729_150833.jpg I tried to load gl4es to make virtio-vga-gl works However,QEMU doesn't want to detect my virgl-server(not virgl_test_server)… How do I get virtio-vga-gl to work?

I don't know what you are trying to do: where is gl4es here: inside qemu vm or outside?

LD_PRELOAD(Copied to /usr/lib/aarch64-linux-gnu/libGL.so.1 later) outside My device is an Android device without OpenGL support. Now i have working virgl server(I can use it to process OpenGLES) And now i need virgl server to process gl4es so i can have a full hardware accelerated OpenGL. So i need to make it works on QEMU(VirGL>GL4ES>QEMU>QEMU's VirtIO-VGA-GL>Guest System). My device has a Mali G77 MC9 GPU.And i'm sure VirGL is working.

Not sure about you shema: gl4es should run outside of Qemu, in your host system, trnslating VirGL call to GLES2.

But what I don't know is what kind of OpenGL context VirGL expect. Does 2.1 is enough? Also, how VirGL opengl OpenGL library? using dlopen I guess. Try maybe to use LD_DEBUG=libs to see what kind of libs qemu is openning and how does it goes (maybe there are some missing export in gl4es).

1.My virgl server can run glmark2-es2,So she can support OpenGLES 2 2.I exported LD_DEBUG=libs,And i got this: Screenshot_20220730_111250.jpg BV1GJ411x7h7

Screenshot_20220806_160532.jpg well… It seems like QEMU need display supports OpenGL.

uhh... I'm now trying to use gtk with gl=on And QEMU was normaly crashed(native OpenGLES) And then i tried to export MESA_GLES_VERSION_OVERRIDE=1.00,And it still doesn't work. At the last time,I tried to run QEMU with LD_PRELOAD=/usr/lib/gl4es/libGL.so.1(gtk supports OpenGL1.1) However, gl4es stops in the startup phase, and qemu cannot start because of this. How can i complete gl4es to make it works?(i'm using VirGL,so i only have EGL and OpenGLES3.2)
