I have some basic questions related to vga16fb. Please provide some inputs and drive us for successful implementation of framebuffer. Even though we are having PCI ATI Rage XL graphic card, we are interested in implementing generic vga16fb for an initial test. Here are my few queries, I read that VESAfb is only for Intel(x86) platforms, has any body implemented Vesafb on other platforms? Is vga16fb a CPU architecture dependent? Even though I didn't find any architecture dependent sections in the code, Is there any code section that to be modified in vga16fb.c? What are the corresponding files need to be modified for implementing framebuffer support for newer platforms. And lastly, we are testing this framebuffer on 2.6Mhz FPGA(0.16 Bogomips) with kernel 2.4.7. Are there any other methods (solutions) for debugging framebuffer code with out using printk's? I request your help.
