First the status :
* The fbd has been ported and it's attaching with the fb0 devie. There's
an fb0 device entry created.
* In the following commit I have added mmap to libbsd. This works like a
wrapper to the mmap in cpukit :
* After the fb0 is created and mmap is added, I don't see anything on
the screen. From the FreeBSD, it seemed like the VT driver is needed
and that is responsible for turning on the screen. So I have ported a
minimal version of the VT with only the initialization and allocate parts:
But even after porting the VT driver which initializes well ( As the
message during booting says). I don't see anything on the screen.
I need some ideas on what is missing or how to debug this.
The app I'm using to test framebuffer is pushed here :
Any idea regarding this is greatly appreciated.
