Embedded display stack documentation?
Hello, I am trying to implement an embedded multi monitor (4) display. As a starter, I bought NVS 420 GPU. I skimmed through "OpenGL ES 3.0 Programming Guide" by Dan Ginsberg, and understood that EGL is a lower level than OpenGL ES. I also keep reading this Qt documentation (http://doc.qt.io/qt-5/embedded-linux.html) over and over, but it's not quite gelling yet: for example, relationship between EGL and eglfs, relationship between eglfs and framebuffer vs. DRI/DRM, etc. Is there some resource that can set me on the right path?
Thank you very much for any kind advice.
