Hi all
I have a question about fb_mmap in uclinux2.4.
what is the usage of fb_mmap(struct file *file, struct vm_area_struct
*vma)
my kernel is arm7 no mmu , does the fb_mmap function do some help for my
framebuffer driver if i use fb_mmap function?
thanks for your help

It (should) behave (almost) the same for uClinux and real Linux.

It allows to mmap() the frame buffer memory (and optionally the graphics chip
registers) to a user space application, e.g. an X server.
