It represents the frame buffer of some video hardware and 13 allows application software to access the graphics hardware through 14 a well-defined interface, so the software doesn't need to know 15 anything about the low-level (hardware register) stuff. 16 17 Frame buffer devices work identically across the different 18 architectures supported by Linux and make the implementation of 19 application programs easier and more portable; at this point, an X 20 server exists which uses the frame buffer device exclusively. 21 On several non-X86 architectures, the frame buffer device is the 22 only way to use the graphics hardware. 23 24 The device is accessed through special device nodes, usually located 25 in the /dev directory, i.e. /dev/fb*. 26 27 You need an utility program called fbset to make full use of frame 28 buffer devices. Please read <file:Documentation/fb/framebuffer.rst> 29 and the Framebuffer-HOWTO at 30 <http://www.munted.org.uk/programming/Framebuffer-HOWTO-1.3.html> for more 31 information. 32 33 This enables support for native frame buffer device (fbdev) drivers. 34 35 The DRM subsystem provides support for emulated frame buffer devices 36 on top of KMS drivers, but this option allows legacy fbdev drivers to 37 be enabled as well. 38 39 Say Y here and to the driver for your graphics board below if you 40 are compiling a kernel for a non-x86 architecture. 41 42 If you are compiling for the x86 architecture, you can say Y if you 43 want to play with it, but it is not essential. Please note that 44 running graphical applications that directly touch the hardware 45 (e.g. an accelerated X server) and that are not frame buffer 46 device-aware may cause unexpected results.

This means you cannot see any output sent to this frame 1666 buffer device, while it does consume precious memory. The main use 1667 of this frame buffer device is testing and debugging the frame 1668 buffer subsystem. Do NOT enable it for normal systems! To protect 1669 the innocent, it has to be enabled explicitly at boot time using the 1670 kernel option `video=vfb:'. 1671 1672 To compile this driver as a module, choose M here: the 1673 module will be called vfb. In order to load it, you must use 1674 the vfb_enable=1 option. 1675 1676 If unsure, say N. 1677 1678config XEN_FBDEV_FRONTEND 1679 tristate "Xen virtual frame buffer support" 1680 depends on FB && XEN 1681 select FB_SYSMEM_HELPERS_DEFERRED 1682 select XEN_XENBUS_FRONTEND 1683 default y 1684 help 1685 This driver implements the front-end of the Xen virtual 1686 frame buffer driver.
