## NAME
       fbdevhw - os-specific submodule for framebuffer device access

## DESCRIPTION
       **fbdevhw**  provides functions for talking to a framebuffer device.  It is os-specific.  It is a
       submodule used by other video drivers.  A **fbdevhw** module is  currently  available  for  linux
       framebuffer devices.

       [fbdev(4)](https://www.chedong.com/phpMan.php/man/fbdev/4/markdown) is a non-accelerated driver which runs on top of the fbdevhw module.  fbdevhw can be
