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.

Works. Use "Insert file..." or external editor.
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Gmail (Web GUI)
If you just have to use Gmail to send patches, it CAN be made to work. It
requires a bit of external help, though.
The first problem is that Gmail converts tabs to spaces. This will
totally break your patches. To prevent this, you have to use a different
editor. There is a firefox extension called "ViewSourceWith"
(https://addons.mozilla.org/en-US/firefox/addon/394) which allows you to
edit any text box in the editor of your choice. Configure it to launch
your favorite editor. When you want to send a patch, use this technique.
Once you have crafted your messsage + patch, save and exit the editor,
which should reload the Gmail edit box. GMAIL WILL PRESERVE THE TABS.
Hoorah. Apparently you can cut-n-paste literal tabs, but Gmail will
convert those to spaces upon sending!
The second problem is that Gmail converts tabs to spaces on replies. If
you reply to a patch, don't expect to be able to apply it as a patch.
The last problem is that Gmail will base64-encode any message that has a
non-ASCII character. That includes things like European names. Be aware.
Gmail is not convenient for lkml patches, but CAN be made to work.

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

internal housekeeping. If the write will update parts of
any basic-blocks on storage, then those blocks should be

@ -0,0 +1,82 @@
The io_mapping functions in linux/io-mapping.h provide an abstraction for
efficiently mapping small regions of an I/O device to the CPU. The initial
usage is to support the large graphics aperture on 32-bit processors where
ioremap_wc cannot be used to statically map the entire aperture to the CPU
as it would consume too much of the kernel address space.
A mapping object is created during driver initialization using
struct io_mapping *io_mapping_create_wc(unsigned long base,
unsigned long size)
'base' is the bus address of the region to be made
mappable, while 'size' indicates how large a mapping region to
enable. Both are in bytes.
This _wc variant provides a mapping which may only be used
with the io_mapping_map_atomic_wc or io_mapping_map_wc.
With this mapping object, individual pages can be mapped either atomically
or not, depending on the necessary scheduling environment. Of course, atomic
maps are more efficient:
void *io_mapping_map_atomic_wc(struct io_mapping *mapping,
unsigned long offset)
'offset' is the offset within the defined mapping region.
Accessing addresses beyond the region specified in the
creation function yields undefined results. Using an offset
which is not page aligned yields an undefined result. The
return value points to a single page in CPU address space.
This _wc variant returns a write-combining map to the
page and may only be used with mappings created by
io_mapping_create_wc
Note that the task may not sleep while holding this page
mapped.
void io_mapping_unmap_atomic(void *vaddr)
'vaddr' must be the the value returned by the last
io_mapping_map_atomic_wc call. This unmaps the specified
page and allows the task to sleep once again.
If you need to sleep while holding the lock, you can use the non-atomic
variant, although they may be significantly slower.
void *io_mapping_map_wc(struct io_mapping *mapping,
unsigned long offset)
This works like io_mapping_map_atomic_wc except it allows
the task to sleep while holding the page mapped.
void io_mapping_unmap(void *vaddr)
This works like io_mapping_unmap_atomic, except it is used
for pages mapped with io_mapping_map_wc.
At driver close time, the io_mapping object must be freed:
void io_mapping_free(struct io_mapping *mapping)
Current Implementation:
The initial implementation of these functions uses existing mapping
mechanisms and so provides only an abstraction layer and no new
functionality.
On 64-bit processors, io_mapping_create_wc calls ioremap_wc for the whole
range, creating a permanent kernel-visible mapping to the resource. The
map_atomic and map functions add the requested offset to the base of the
virtual address returned by ioremap_wc.
On 32-bit processors with HIGHMEM defined, io_mapping_map_atomic_wc uses
kmap_atomic_pfn to map the specified page in an atomic fashion;
kmap_atomic_pfn isn't really supposed to be used with device pages, but it
provides an efficient mapping for this usage.
On 32-bit processors without HIGHMEM defined, io_mapping_map_atomic_wc and
io_mapping_map_wc both use ioremap_wc, a terribly inefficient function which
performs an IPI to inform all processors about the new mapping. This results
in a significant performance penalty.
