Hi,

You'll find attached a driver for the Sony Programmable I/O
Control Device, which can be found on many (all ?) Sony Vaio
laptops.

This driver enables a user mode application to receive (through
a misc character device node) the events generated by:
	- the jogdial (the small wheel)
	- the capture button (on picture book series)
	- the Fn keys (on some laptops only)
	- the bluetooth button (if you have one :-) ).

A sample application, demonstrating the polling of the character
device and translating the jogdial events into X mousewheel events
can be found at:
	http://mapage.noos.fr/pop/sonypi/sonypid.tar.gz
(note that this location is different from the one documented
in Documentation/sonypi.txt, since the latter is rather slow to
update, but it will be the the stable one).

This driver is also a prerequisite for the video4linux driver
for the Motion Eye camera (found on Vaio Picturebook series),
which I wrote and I'm cleaning up a bit right now, before I send
it on the list, probably by the end of this week.

The patch is attached below and should apply cleanly on 2.4.5.

Thanks,

Stelian.

+
+This driver enables access to the Sony Programmable I/O Control Device which
+can be found in many (all ?) Sony Vaio laptops.
+
+It will give access (through a user space utility) to some events those laptops
+generate, like:
+	- jogdial events (the small wheel on the side of Vaios)
+	- capture button events (only on Vaio Picturebook series)
+	- Fn keys
+	- bluetooth button (only on C1VR model)
+
+Those events (see linux/sonypi.h) can be polled using the character device node
+/dev/sonypi (major 10, minor auto allocated or specified as a option).
+
+A simple daemon which translates the jogdial movements into mouse wheel events
+can be downloaded at: <http://www.alcove-labs.org/en/software/sonypi/>
+
+This driver can also be used to set the camera controls on Picturebook series
+(brightness, contrast etc), and is used by the video4linux driver for the 
+Motion Eye camera.
+
+Please note that this driver was created by reverse engineering the Windows
+driver and the ACPI BIOS, because Sony doesn't agree to release any programming
+specs for its laptops. If someone convinces them to do so, drop me a note.
+
+Module options:
+---------------
+
+	minor: 		minor number of the misc device /dev/sonypi, 
+			default is -1 (automatic allocation, see /proc/misc
+			or kernel logs)
+
+	verbose:	print unknown events from the sonypi device
+
+Bugs:
+-----
+
+	- the Fn keys events seem to work on some Vaio models, but not on others
+	  (it doesn't work on C1VE, C1VR)...
