Below you will find an updated version from the original series bunching all patches into one big patch updating broken web addresses that are located in Documentation/* Some of the addresses date as far far back as 1995 etc... so searching became a bit difficult, the best way to deal with these is to use web.archive.org to locate these addresses that are outdated. Now there are also some addresses pointing to .spec files some are located, but some(after searching on the companies site)where still no where to be found. In this case I just changed the address to the company site this way the users can contact the company and they can locate them for the users. Signed-off-by: Justin P.

BCM5974 Driver (bcm5974)

The BCM5974 driver is based on the appletouch driver:

This driver adds support for the multi-touch trackpad on the new Apple
|
|
Macbook Air and Macbook Pro laptops. It replaces the appletouch driver on
|
|
those computers, and integrates well with the synaptics driver of the Xorg
|
|
system.
|
|
|
|
Known to work on Macbook Air, Macbook Pro Penryn and the new unibody
|
|
Macbook 5 and Macbook Pro 5.
|
|
|
|
Usage
|
|
-----
|
|
|
|
The driver loads automatically for the supported usb device ids, and
|
|
becomes available both as an event device (/dev/input/event*) and as a
|
|
mouse via the mousedev driver (/dev/input/mice).
|
|
|
|
USB Race
|
|
--------
|
|
|
|
The Apple multi-touch trackpads report both mouse and keyboard events via
|
|
different interfaces of the same usb device. This creates a race condition
|
|
with the HID driver, which, if not told otherwise, will find the standard
|
|
HID mouse and keyboard, and claim the whole device. To remedy, the usb
|
|
product id must be listed in the mouse_ignore list of the hid driver.
|
|
|
|
Debug output
|
|
------------
|
|
|
|
To ease the development for new hardware version, verbose packet output can
|
|
be switched on with the debug kernel module parameter. The range [1-9]
|
|
yields different levels of verbosity. Example (as root):
|
|
|
|
echo -n 9 > /sys/module/bcm5974/parameters/debug
|
|
|
|
tail -f /var/log/debug
|
|
|
|
echo -n 0 > /sys/module/bcm5974/parameters/debug
|
|
|
|
Trivia
|
|
------
|
|
|
|
The driver was developed at the ubuntu forums in June 2008 [1], and now has
|
|
a more permanent home at bitmath.org [2].
