tristate "Support for frame buffer device drivers"

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

If you say Y, then the VESA standard, Generalized Timing Formula

(nondiscrete being a range of values as opposed to discrete being a

and vertical resolutions, and vertical refresh rates without having
to specify your own timing parameters. This is especially useful

monitor is recommended, but can still work with non-compliant ones.

If you need support for G400 secondary head, you must say Y to
"Matrox I2C support" and "G400 second head support" right below.
G450/G550 secondary head and digital output are supported without
additional modules.
The driver starts in monitor mode. You must use the matroxset tool
(available at <ftp://platan.vc.cvut.cz/pub/linux/matrox-latest/>) to
swap primary and secondary head outputs, or to change output mode.
Secondary head driver always start in 640x480 resolution and you
must use fbset to change it.
Do not forget that second head supports only 16 and 32 bpp
packed pixels, so it is a good idea to compile them into the kernel
too. You can use only some font widths, as the driver uses generic
painting procedures (the secondary head does not use acceleration
engine).
G450/G550 hardware can display TV picture only from secondary CRTC,
and it performs no scaling, so picture must have 525 or 625 lines.

WARNING !!! This support does not work with G450 !!!
Say Y or M here if you want to use a secondary head (meaning two
monitors in parallel) on G400 or MGA-TVO add-on on G200. Secondary
head is not compatible with accelerated XFree 3.3.x SVGA servers -
secondary head output is blanked while you are in X. With XFree
3.9.17 preview you can use both heads if you use SVGA over fbdev or
the fbdev driver on first head and the fbdev driver on second head.
If you compile it as module, two modules are created,
matroxfb_crtc2 and matroxfb_maven. Matroxfb_maven is needed for
both G200 and G400, matroxfb_crtc2 is needed only by G400. You must
also load i2c-matroxfb to get it to run.
The driver starts in monitor mode and you must use the matroxset
tool (available at
<ftp://platan.vc.cvut.cz/pub/linux/matrox-latest/>) to switch it to
PAL or NTSC or to swap primary and secondary head outputs.

config FB_VIRTUAL
tristate "Virtual Frame Buffer support (ONLY FOR TESTING!)"
depends on FB
select FB_SYSMEM_HELPERS
help
This is a `virtual' frame buffer device. It operates on a chunk of
unswappable kernel memory instead of on the memory of a graphics
board. This means you cannot see any output sent to this frame
buffer device, while it does consume precious memory. The main use
of this frame buffer device is testing and debugging the frame
buffer subsystem. Do NOT enable it for normal systems! To protect
the innocent, it has to be enabled explicitly at boot time using the
kernel option `video=vfb:'.
To compile this driver as a module, choose M here: the
module will be called vfb. In order to load it, you must use
the vfb_enable=1 option.
If unsure, say N.

Say Y if you want support for a simple frame-buffer.
This driver assumes that the display hardware has been initialized
before the kernel boots, and the kernel will simply render to the
pre-allocated frame buffer surface.
Configuration re: surface address, size, and format must be provided
through device tree, or plain old platform data.
