Rosimildo,
As I think about this a little more, one important factor is
whether or not RTEMS wants to support graphics mode for
console operation. This adds complexity. If merely a framebuffer
is desired, it is quite a bit simpler, because all RTEMS has to manage
is the switch between text and graphics, video init, and the actual
framebuffer mapping.
To support a graphics console, there have to be quite a few more entry points,
and the framebuffer code has to support being accessible inside
the kernel, rather than just address-mapped video memory access to
applications.
Frank's PK supports a graphics console, and he has kept the
system quite simple. Perhaps his code is a good place to start.
