What:		/sys/kernel/uids/<uid>/cpu_shares
Date:		December 2007
Contact:	Dhaval Giani <dhaval@linux.vnet.ibm.com>
		Srivatsa Vaddagiri <vatsa@linux.vnet.ibm.com>
Description:
		The /sys/kernel/uids/<uid>/cpu_shares tunable is used
		to set the cpu bandwidth a user is allowed. This is a
		propotional value. What that means is that if there
		are two users logged in, each with an equal number of
		shares, then they will get equal CPU bandwidth. Another
		example would be, if User A has shares = 1024 and user
		B has shares = 2048, User B will get twice the CPU
		bandwidth user A will. For more details refer
		Documentation/sched-design-CFS.txt

This is an explanation of what i2c is, and what is supported in this package.

I2C and SMBus
=============

@@ -33,52 +31,17 @@ When we talk about I2C, we use the following terms:
            Client

An Algorithm driver contains general code that can be used for a whole class
of I2C adapters. Each specific adapter driver depends on one algorithm
driver.
of I2C adapters. Each specific adapter driver either depends on one algorithm
driver, or includes its own implementation.

A Driver driver (yes, this sounds ridiculous, sorry) contains the general
code to access some type of device. Each detected device gets its own
data in the Client structure. Usually, Driver and Client are more closely
integrated than Algorithm and Adapter.

For a given configuration, you will need a driver for your I2C bus (usually
a separate Adapter and Algorithm driver), and drivers for your I2C devices
(usually one driver for each device). There are no I2C device drivers
in this package. See the lm_sensors project http://www.lm-sensors.nu
for device drivers.
For a given configuration, you will need a driver for your I2C bus, and
drivers for your I2C devices (usually one driver for each device).

At this time, Linux only operates I2C (or SMBus) in master mode; you can't
use these APIs to make a Linux system behave as a slave/device, either to
speak a custom protocol or to emulate some other device.


Included Bus Drivers
====================
Note that only stable drivers are patched into the kernel by 'mkpatch'.


Base modules
------------

i2c-core: The basic I2C code, including the /proc/bus/i2c* interface
i2c-dev:  The /dev/i2c-* interface
i2c-proc: The /proc/sys/dev/sensors interface for device (client) drivers

Algorithm drivers
-----------------

i2c-algo-bit:    A bit-banging algorithm
i2c-algo-pcf:    A PCF 8584 style algorithm
i2c-algo-ibm_ocp: An algorithm for the I2C device in IBM 4xx processors (NOT BUILT BY DEFAULT)

Adapter drivers
---------------

i2c-elektor:     Elektor ISA card (uses i2c-algo-pcf)
i2c-elv:         ELV parallel port adapter (uses i2c-algo-bit)
i2c-pcf-epp:     PCF8584 on a EPP parallel port (uses i2c-algo-pcf) (NOT mkpatched)
i2c-philips-par: Philips style parallel port adapter (uses i2c-algo-bit)
i2c-adap-ibm_ocp: IBM 4xx processor I2C device (uses i2c-algo-ibm_ocp) (NOT BUILT BY DEFAULT)
i2c-pport:       Primitive parallel port adapter (uses i2c-algo-bit)
i2c-velleman:    Velleman K8000 parallel port adapter (uses i2c-algo-bit)
