-The initial design is to go in your car, but you can use it at home, on a

-MPEG technology onto a hard disk in the unit, and use the power of the
-embedded computer to serve up the music you want.

-The Kenwood KCA-R6A remote control generates a sequence like the following:
-
-Go low for approx 16T (Around 9000us)
-Go high for approx 8T (Around 4000us)
-Go low for less than 2T (Around 750us)
-
-For each of the 32 bits
- Go high for more than 2T (Around 1500us) == 1
- Go high for less than T (Around 400us) == 0
- Go low for less than 2T (Around 750us)
-
-Rather than repeat a signal when the button is held down certain buttons
-generate the following code to indicate repetition.
-
-Go low for approx 16T
-Go high for approx 4T
-Go low for less than 2T
-
-(By removing the <2T from the start of the sequence and placing at the end
- it can be considered a stop bit but I found it easier to deal with it at
- the start).
-
-The 32 bits are encoded as XxYy where x and y are the actual data values
-while X and Y are the logical inverses of the associated data values. Using
-LSB first yields sensible codes for the numbers.
-
-All codes are of the form b9xx
-
-The numeric keys generate the code 0x where x is the number pressed.

readpages is only used for read-ahead, so read errors are
ignored. If anything goes wrong, feel free to give up.
- prepare_write: called by the generic write path in VM to set up a write
- request for a page. This indicates to the address space that
- the given range of bytes is about to be written. The
- address_space should check that the write will be able to
- complete, by allocating space if necessary and doing any other
- internal housekeeping. If the write will update parts of
- any basic-blocks on storage, then those blocks should be
- pre-read (if they haven't been read already) so that the
- updated blocks can be written out properly.
- The page will be locked.
-
- Note: the page _must not_ be marked uptodate in this function
- (or anywhere else) unless it actually is uptodate right now. As
- soon as a page is marked uptodate, it is possible for a concurrent
- read(2) to copy it to userspace.
-
- commit_write: If prepare_write succeeds, new data will be copied
- into the page and then commit_write will be called. It will
- typically update the size of the file (if appropriate) and
- mark the inode as dirty, and do any other related housekeeping
- operations. It should avoid returning an error if possible -
- errors should have been handled by prepare_write.
-
- write_begin: This is intended as a replacement for prepare_write. The
- key differences being that:
- - it returns a locked page (in *pagep) rather than being
- given a pre locked page;
- - it must be able to cope with short writes (where the
- length passed to write_begin is greater than the number
- of bytes copied into the page).
-
+ write_begin:
Called by the generic buffered write code to ask the filesystem to
prepare to write len bytes at the given offset in the file. The
address_space should check that the write will be able to complete,
The filesystem must return the locked pagecache page for the specified
offset, in *pagep, for the caller to write into.

- * DS1286 Real Time Clock interface for Linux
- *
- * Copyright (C) 1998, 1999, 2000 Ralf Baechle
- *
- * Based on code written by Paul Gortmaker.
- *
- * This driver allows use of the real time clock (built into nearly all
- * computers) from user space. It exports the /dev/rtc interface supporting
- * various ioctl() and also the /proc/rtc pseudo-file for status
- * information.
- *
- * The ioctls can be used to set the interrupt behaviour and generation rate
- * from the RTC via IRQ 8. Then the /dev/rtc interface can be used to make
- * use of these timer interrupts, be they interval or alarm based.
- *
- * The /dev/rtc interface will block on reads until an interrupt has been
- * received. If a RTC interrupt has already happened, it will output an
- * unsigned long and then block. The output value contains the interrupt
- * status in the low byte and the number of interrupts since the last read
- * in the remaining high bytes. The /dev/rtc interface can also be used with
- * the select(2) call.
- *
- * This program is free software; you can redistribute it and/or modify it
- * under the terms of the GNU General Public License as published by the
- * Free Software Foundation; either version 2 of the License, or (at your
- * option) any later version.
