Basically I'm working with a scenario of two independent video decoding pipeline which allows to get two video displayed on two TV. In this context, I would like to manage two independent framebuffers on each video decoding. So, is it possible to have 2 concurrent virtual consoles running on the two monitors simultaneously (for example two independent console on the /dev/fb0 and /dev/fb1 framebuffers at the same time) ? Looking at the register_framebuffer function, when the first frame buffer device /dev/fb0 is registered, it calls the take_over_console function (exported by drivers/char/console.c) in order to actually set up the current frame buffer as the system console. But, when the second framebuffer (/dev/fb1) is registered, the register_framebuffer function doesn't set any system console for the /dev/fb1 device. Is there some linux kernel version (or patch) which allows to manage the described scenario? Thanks a lot for any feedback, Best regards OP.
