I need to enable support for an external graphics card through a pcmcia slot - the driver for which does not exist. As this is my first in terms of device driver writing, I would be grateful for some advice. Is it possible to write this additional driver as a dynamic kernel module (along the lines of fbmem.c which is static), which however itself implements all device specific functions? Can this make use of the same ioctl functions that fbmem.c uses (defined in fb.h)? Would there be a conflict considering that fbmem would remain in the system? Alternately if i am to write this as a static module (which loads onto fbmem.c) - is there any way i could test it out without having to recompile the kernel repeatedly? Any other suggestions on how to proceed would be very welcome.
