Some of you may be aware that we are currently collecting beta tester
applications for the coming beta of our SciTech Display Doctor for
Linux product. SDD for Linux incorporates our new SciTech Nucleus
Graphics Architecture drivers, and as such I am investigating what it
would take to make our device driver support work with fbcon for the
Linux framebuffer console.
Now I am completely ignorant of how the fbcon stuff works in the
latest kernels, but one of the things that we will need in order to
support this is the ability access the file system so we can
dynamically load our Nucleus drivers from disk. The code to load the
drives simply relies upon standard C file I/O functions (which may
not be available in the kernel, but some sort of file I/O must be?)
and is pure, portable C code so that can compile for the kernel just
fine. However when does the fbcon stuff get initialised, and can it
be initialised late enough in the bootup sequence such that the
device drivers for the console can be loaded from the file system?
What sort of problems are we going to have to face getting our driver
loading code working in the kernel?
Thanks!
