The first file that you mention is part of the Linux drm driver (the rest is the other files in that folder). I wrote the driver, based on in-kernel ones, but I am not an expert in the kernel drm subsystem, and in particular I only use the basic kernel fbdev translation functions to provide the framebuffer driver. You would probably be better asking on the dri-devel list<1> about what to change to get one fbdev device per head. You might be in luck and there might be a simple solution. >
Yes, I was asking on irc, but I think I fallen in lunch mode there, so only silence :) That is why I asked here again. Anyway, thanks for the hints! I definitely will have a try with drm. But it's good that the author of driver is reachable. So more questions can come later ;) CU /Jan > Regards, > > Michael > > <1> https://lists.freedesktop.org/mailman/listinfo/dri-devel > > > On 05.09.2016 17:42, Jan Petrouš wrote: >> >> Hi, >> >> as VirtualBox supports dual head config I was trying to start two >> framebuffers on it. >> But unsucessfull. >> >> The main constraint is that guest Linux is very tiny and has no >> X-Windows inside. >> The application requires only the framebuffer devices. >> >> I did many hours googling to find solution but I found only solution for >> xwin environment. >> >> Is it even possible to enable two FB devices on dualhead configuration? >> >> If the answer is NO, can you show me where I should start to look inside >> the sources? >> >> I found the VB Additions subversion repo where are at least two video >> drivers: >> >> 1, >> http://www.virtualbox.org/svn/vbox/trunk/src/VBox/Additions/linux/drm/vbox_fb.c >> 2, >> http://www.virtualbox.org/svn/vbox/trunk/src/VBox/Additions/x11/vboxvideo/vboxvideo.c >> >> I guess that the driver for my non-x11 environment is the first one.
