Linux Device Drivers Development

Detailed fb_ops

Let us describe some of the hooks declared in fb_ops structure. That being said, for an idea on writing framebuffer drivers, you can have a look at drivers/video/fbdev/vfb.c, which is a simple virtual framebuffer driver in the kernel. You can also have a look at other specific framebuffer drivers, such as the i.MX6 driver, at drivers/video/fbdev/imxfb.c, or at the kernel documentation about framebuffer driver APIs at Documentation/fb/api.txt.
