KD_GRAPHICS kernel emulation mode with EGLFS
-
According to https://unix.stackexchange.com/questions/173712/best-practice-for-hiding-virtual-console-while-rendering-video-to-framebuffer it is best practice to put the virtual terminal into the KD_GRAPHICS mode for disabling eventual kernel outputs.
Although this seems perfectly possible with the LinuxFB plugin (enabled by default considering http://doc.qt.io/qt-5/embedded-linux.html#linuxfb) it is unspecified if this applies also for EGLFS.
Unfortunately I find no further explanation in this regard, so please give me some hint if it makes sense or not!
