[Interest] QPA / EGLFS / OpenGL

[Bell, Andrew [Allen & Heath UK]]

Hi All

I was hoping someone could set me straight on EGLFS vs DirectFB / XCB.

I'm developing on an iMX6 using a Yocto built distro.

I don't have X or wayland in my distro, but I do want to use opengl, and I've managed to build Qt with es2 enabled.

Can someone tell me which level of support the different QPA flavors provide for opengl.

Should I be using EGLFS or DirectFB ?

Will the straight FB have basic opengl es2 support or none ?

Any info on the QPA's support for opengl would be really useful.

TIA

Andrew.
