-<P>
-<H3>Frame Buffer</H3>
-Capture cards that drop data directly onto the frame buffer must be told the
-base address of the frame buffer, its size and organisation. This is a 
-privileged ioctl and one that eventually X itself should set.
-<P>
-The <b>VIDIOCSFBUF</b> ioctl sets the frame buffer parameters for a capture
-card. If the card does not do direct writes to the frame buffer then this
-ioctl will be unsupported. The <b>VIDIOCGFBUF</b> ioctl returns the
-currently used parameters. The structure used in both cases is a

-Note that these values reflect the physical layout of the frame buffer. 
-The visible area may be smaller. In fact under XFree86 this is commonly the

-Setting the base address to NULL indicates there is no physical frame buffer
-access.
-<P>
-<H3>Capture Windows</H3>
-The capture area is described by a <b>struct video_window</b>. This defines
-a capture area and the clipping information if relevant. The 
-<b>VIDIOCGWIN</b> ioctl recovers the current settings and the 
-<b>VIDIOCSWIN</b> sets new values. A successful call to <b>VIDIOCSWIN</b> 
-indicates that a suitable set of parameters have been chosen. They do not
-indicate that exactly what was requested was granted. The program should
-call <b>VIDIOCGWIN</b> to check if the nearest match was suitable. The

-<H3>Reading Images</H3>
-Each call to the <b>read</b> syscall returns the next available image
-from the device. It is up to the caller to set format and size (using
-the VIDIOCSPICT and VIDIOCSWIN ioctls) and then to pass a suitable
-size buffer and length to the function. Not all devices will support
-read operations.
-<P>
-A second way to handle image capture is via the mmap interface if supported.
-To use the mmap interface a user first sets the desired image size and depth
-properties. Next the VIDIOCGMBUF ioctl is issued. This reports the size
-of buffer to mmap and the offset within the buffer for each frame. The
-number of frames supported is device dependent and may only be one. 
-<P>
-The video_mbuf structure contains the following fields
-<P>
-<TABLE>
-<TR><TD><b>size</b><TD>The number of bytes to map</TD>
-<TR><TD><b>frames</b><TD>The number of frames</TD>
-<TR><TD><b>offsets</b><TD>The offset of each frame</TD>
-</TABLE>
-<P>
-Once the mmap has been made the VIDIOCMCAPTURE ioctl starts the
-capture to a frame using the format and image size specified in the
-video_mmap (which should match or be below the initial query size).
-When the VIDIOCMCAPTURE ioctl returns the frame is <em>not</em>
-captured yet, the driver just instructed the hardware to start the
-capture.  The application has to use the VIDIOCSYNC ioctl to wait
-until the capture of a frame is finished.  VIDIOCSYNC takes the frame
-number you want to wait for as argument.
-<p>
-It is allowed to call VIDIOCMCAPTURE multiple times (with different
-frame numbers in video_mmap->frame of course) and thus have multiple
-outstanding capture requests.  A simple way do to double-buffering
-using this feature looks like this:
-<pre>
-/* setup everything */
-VIDIOCMCAPTURE(0)
-while (whatever) {
-   VIDIOCMCAPTURE(1)
-   VIDIOCSYNC(0)
-   /* process frame 0 while the hardware captures frame 1 */
-   VIDIOCMCAPTURE(0)
-   VIDIOCSYNC(1)
-   /* process frame 1 while the hardware captures frame 0 */
-}
-</pre>
-Note that you are <em>not</em> limited to only two frames.  The API
-allows up to 32 frames, the VIDIOCGMBUF ioctl returns the number of
-frames the driver granted.  Thus it is possible to build deeper queues
-to avoid loosing frames on load peaks.
-<p>
-While capturing to memory the driver will make a "best effort" attempt
-to capture to screen as well if requested. This normally means all
-frames that "miss" memory mapped capture will go to the display.
-<P>
-A final ioctl exists to allow a device to obtain related devices if a
-driver has multiple components (for example video0 may not be associated
-with vbi0 which would cause an intercast display program to make a bad
-mistake). The VIDIOCGUNIT ioctl reports the unit numbers of the associated
-devices if any exist. The video_unit structure has the following fields.
-<P>
-<TABLE>
-<TR><TD><b>video</b><TD>Video capture device</TD>
-<TR><TD><b>vbi</b><TD>VBI capture device</TD>

-<H3>RDS Datastreams</H3>
-For radio devices that support it, it is possible to receive Radio Data
-System (RDS) data by means of a read() on the device.  The data is packed in
-groups of three, as follows:
-<TABLE>
-<TR><TD>First Octet</TD><TD>Least Significant Byte of RDS Block</TD></TR>

-
-   1) umul_ppmm(high_prod, low_prod, multipler, multiplicand)
-   multiplies two u32 integers MULTIPLER and MULTIPLICAND,
-   and generates a two-part u32 product in HIGH_PROD and
-   LOW_PROD.
-
-   2) __umulsidi3(a,b) multiplies two u32 integers A and B,
-   and returns a u64 product.  This is just a variant of umul_ppmm.
-
-   3) udiv_qrnnd(quotient, remainder, high_numerator, low_numerator,
-   denominator) divides a two-word unsigned integer, composed by the
-   integers HIGH_NUMERATOR and LOW_NUMERATOR, by DENOMINATOR and
-   places the quotient in QUOTIENT and the remainder in REMAINDER.
-   HIGH_NUMERATOR must be less than DENOMINATOR for correct operation.
-   If, in addition, the most significant bit of DENOMINATOR must be 1,
-   then the pre-processor symbol UDIV_NEEDS_NORMALIZATION is defined to 1.
-
-   4) sdiv_qrnnd(quotient, remainder, high_numerator, low_numerator,
-   denominator).  Like udiv_qrnnd but the numbers are signed.  The
-   quotient is rounded towards 0.
-
-   5) count_leading_zeros(count, x) counts the number of zero-bits from
-   the msb to the first non-zero bit.  This is the number of steps X
-   needs to be shifted left to set the msb.  Undefined for X == 0.
-
-   6) add_ssaaaa(high_sum, low_sum, high_addend_1, low_addend_1,
-   high_addend_2, low_addend_2) adds two two-word unsigned integers,
-   composed by HIGH_ADDEND_1 and LOW_ADDEND_1, and HIGH_ADDEND_2 and
-   LOW_ADDEND_2 respectively.  The result is placed in HIGH_SUM and
-   LOW_SUM.  Overflow (i.e. carry out) is not stored anywhere, and is
-   lost.
-
-   7) sub_ddmmss(high_difference, low_difference, high_minuend,
-   low_minuend, high_subtrahend, low_subtrahend) subtracts two
-   two-word unsigned integers, composed by HIGH_MINUEND_1 and
-   LOW_MINUEND_1, and HIGH_SUBTRAHEND_2 and LOW_SUBTRAHEND_2
-   respectively.  The result is placed in HIGH_DIFFERENCE and
-   LOW_DIFFERENCE.  Overflow (i.e. carry out) is not stored anywhere,
-   and is lost.
-
-   If any of these macros are left undefined for a particular CPU,
-   C macros are used.  */

-        ---help---
-          If you intend to attach a printer to the parallel port of your Linux
-          box (as opposed to using a serial printer; if the connector at the
-          printer has 9 or 25 holes ["female"], then it's serial), say Y.
-          Also read the Printing-HOWTO, available from
-          <http://www.tldp.org/docs.html#howto>.
-
-          It is possible to share one parallel port among several devices
-          (e.g. printer and ZIP drive) and it is safe to compile the
-          corresponding drivers into the kernel.  If you want to compile this
-          driver as a module however, choose M here and read
-          <file:Documentation/parport.txt>.  The module will be called lp.
-
-          If you have several parallel ports, you can specify which ports to
-          use with the "lp" kernel command line option.  (Try "man bootparam"
-          or see the documentation of your boot loader (silo) about how to pass
-          options to the kernel at boot time.)  The syntax of the "lp" command
-          line option can be found in <file:drivers/char/lp.c>.
-
-          If you have more than 8 printers, you need to increase the LP_NO
-          macro in lp.c and the PARPORT_MAX macro in parport.h.

- * The following define the access methods for the HUB6 card. All
- * access is through two ports for all 24 possible chips. The card is
- * selected through the high 2 bits, the port on that card with the
- * "middle" 3 bits, and the register on that port with the bottom
- * 3 bits.
- *
- * While the access port and interrupt is configurable, the default
- * port locations are 0x302 for the port control register, and 0x303
- * for the data read/write register. Normally, the interrupt is at irq3
- * but can be anything from 3 to 7 inclusive. Note that using 3 will
