---------------------------
What: find_trylock_page
When: January 2007
Why: The interface no longer has any callers left in the kernel. It
is an odd interface (compared with other find_*_page functions), in
that it does not take a refcount to the page, only the page lock.
It should be replaced with find_get_page or find_lock_page if possible.
This feature removal can be reevaluated if users of the interface
cannot cleanly use something else.

LED handling under Linux
========================
If you're reading this and thinking about keyboard leds, these are
handled by the input subsystem and the led class is *not* needed.
In its simplest form, the LED class just allows control of LEDs from
userspace. LEDs appear in /sys/class/leds/. The brightness file will
set the brightness of the LED (taking a value 0-255). Most LEDs don't
have hardware brightness support so will just be turned on for non-zero
brightness settings.
The class also introduces the optional concept of an LED trigger. A trigger
is a kernel based source of led events. Triggers can either be simple or
complex. A simple trigger isn't configurable and is designed to slot into
existing subsystems with minimal additional code. Examples are the ide-disk,
nand-disk and sharpsl-charge triggers. With led triggers disabled, the code
optimises away.
Complex triggers whilst available to all LEDs have LED specific
parameters and work on a per LED basis. The timer trigger is an example.
You can change triggers in a similar manner to the way an IO scheduler
is chosen (via /sys/class/leds/<device>/trigger). Trigger specific
parameters can appear in /sys/class/leds/<device> once a given trigger is
selected.
Design Philosophy
=================
The underlying design philosophy is simplicity. LEDs are simple devices
and the aim is to keep a small amount of code giving as much functionality
as possible. Please keep this in mind when suggesting enhancements.
LED Device Naming
=================
Is currently of the form:
"devicename:colour"
There have been calls for LED properties such as colour to be exported as
individual led class attributes. As a solution which doesn't incur as much
overhead, I suggest these become part of the device name. The naming scheme
above leaves scope for further attributes should they be needed.
Known Issues
============
The LED Trigger core cannot be a module as the simple trigger functions
would cause nightmare dependency issues. I see this as a minor issue
compared to the benefits the simple trigger functionality brings. The
rest of the LED subsystem can be modular.
Some leds can be programmed to flash in hardware. As this isn't a generic
LED device property, this should be exported as a device specific sysfs
attribute rather than part of the class if this functionality is required.
Future Development
==================
At the moment, a trigger can't be created specifically for a single LED.
There are a number of cases where a trigger might only be mappable to a
particular LED (ACPI?). The addition of triggers provided by the LED driver
should cover this option and be possible to add without breaking the
current interface.

BCM43xx Linux Driver Project
============================
About this software
-------------------
The goal of this project is to develop a linux driver for Broadcom
BCM43xx chips, based on the specification at
http://bcm-specs.sipsolutions.net/
The project page is http://bcm43xx.berlios.de/
Requirements
------------
1) Linux Kernel 2.6.16 or later
http://www.kernel.org/
You may want to configure your kernel with:
CONFIG_DEBUG_FS (optional):
-> Kernel hacking
-> Debug Filesystem
2) SoftMAC IEEE 802.11 Networking Stack extension and patched ieee80211
modules:
http://softmac.sipsolutions.net/
3) Firmware Files
Please try fwcutter. Fwcutter can extract the firmware from various
binary driver files. It supports driver files from Windows, MacOS and
Linux. You can get fwcutter from http://bcm43xx.berlios.de/.
Also, fwcutter comes with a README file for further instructions.

help
The kernel needs to change the hardware exception vectors.
In nommu mode, the hardware exception vectors are normally
placed at address 0x00000000. However, this region may be
occupied by read-only memory depending on H/W design.
If the region contains read-write memory, say 'n' here.
If your CPU provides a remap facility which allows the exception
vectors to be mapped to writable memory, say 'n' here.
Otherwise, say 'y' here. In this case, the kernel will require
external support to redirect the hardware exception vectors to
the writable versions located at DRAM_BASE.
