A bunch of drivers use ISA DMA helpers or their equivalents for platforms that have ISA with different DMA controller (a lot of ARM boxen). Currently there is no way to put such dependency in Kconfig - CONFIG_ISA is not it (e.g. it is not set on platforms that have no ISA slots, but have on-board devices that pretend to be ISA ones). New symbol added - ISA_DMA_API. Set when we have functional enable_dma()/set_dma_mode()/etc. set of helpers. Next patches in the series will add missing dependencies for drivers that need them. I'm very carefully staying the hell out of the recurring flamefest on what exactly CONFIG_ISA would mean in ideal world - added symbol has a well-defined meaning and for now I really want to treat it as completely independent from the mess around CONFIG_ISA.

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.txt>
|
|
and the Framebuffer-HOWTO at <http://www.tldp.org/docs.html#howto>
|
|
for more information.
|
|
|
|
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.

Select this option if you want to run o32 binaries. These are pure

32-bit binaries as used by the 32-bit Linux/MIPS port. Most of

existing binaries are in this format.

Select this option if you want to run n32 binaries. These are

64-bit binaries using 32-bit quantities for addressing and certain

data that would normally be 64-bit. They are used in special

cases.
