Supporting multiple CPU idle levels in kernel
cpuidle
General Information:
Various CPUs today support multiple idle levels that are differentiated
by varying exit latencies and power consumption during idle.
cpuidle is a generic in-kernel infrastructure that separates
idle policy (governor) from idle mechanism (driver) and provides a
standardized infrastructure to support independent development of
governors and drivers.
cpuidle resides under drivers/cpuidle.
Boot options:
"cpuidle_sysfs_switch"
enables current_governor interface in /sys/devices/system/cpu/cpuidle/,
which can be used to switch governors at run time. This boot option
is meant for developer testing only. In normal usage, kernel picks the
best governor based on governor ratings.

Supporting multiple CPU idle levels in kernel
cpuidle drivers
cpuidle driver hooks into the cpuidle infrastructure and handles the
architecture/platform dependent part of CPU idle states. Driver
provides the platform idle state detection capability and also
has mechanisms in place to support actual entry-exit into CPU idle states.
cpuidle driver initializes the cpuidle_device structure for each CPU device
and registers with cpuidle using cpuidle_register_device.
It can also support the dynamic changes (like battery <-> AC), by using
cpuidle_pause_and_lock, cpuidle_disable_device and cpuidle_enable_device,
cpuidle_resume_and_unlock.
Interfaces:
extern int cpuidle_register_driver(struct cpuidle_driver *drv);

Supporting multiple CPU idle levels in kernel
cpuidle governors
cpuidle governor is policy routine that decides what idle state to enter at
any given time. cpuidle core uses different callbacks to the governor.
* enable() to enable governor for a particular device
* disable() to disable governor for a particular device
* select() to select an idle state to enter
* reflect() called after returning from the idle state, which can be used
by the governor for some record keeping.
More than one governor can be registered at the same time and
users can switch between drivers using /sysfs interface (when enabled).
More than one governor part is supported for developers to easily experiment
with different governors. By default, most optimal governor based on your
kernel configuration and platform will be selected by cpuidle.
Interfaces:
extern int cpuidle_register_governor(struct cpuidle_governor *gov);

Kernel driver adt7473
======================
Supported chips:
* Analog Devices ADT7473
Prefix: 'adt7473'
Addresses scanned: I2C 0x2C, 0x2D, 0x2E
Datasheet: Publicly available at the Analog Devices website
Author: Darrick J. Wong
Description
-----------
This driver implements support for the Analog Devices ADT7473 chip family.
The LM85 uses the 2-wire interface compatible with the SMBUS 2.0
specification. Using an analog to digital converter it measures three (3)
temperatures and two (2) voltages. It has three (3) 16-bit counters for
measuring fan speed. There are three (3) PWM outputs that can be used
to control fan speed.
A sophisticated control system for the PWM outputs is designed into the
LM85 that allows fan speed to be adjusted automatically based on any of the
three temperature sensors. Each PWM output is individually adjustable and
programmable. Once configured, the ADT7473 will adjust the PWM outputs in
response to the measured temperatures without further host intervention.
This feature can also be disabled for manual control of the PWM's.
Each of the measured inputs (voltage, temperature, fan speed) has
corresponding high/low limit values. The ADT7473 will signal an ALARM if
any measured value exceeds either limit.
The ADT7473 samples all inputs continuously. The driver will not read
the registers more often than once every other second. Further,
configuration data is only read once per minute.
Special Features
----------------
The ADT7473 have a 10-bit ADC and can therefore measure temperatures
with 0.25 degC resolution. Temperature readings can be configured either
for twos complement format or "Offset 64" format, wherein 63 is subtracted
from the raw value to get the temperature value.
The Analog Devices datasheet is very detailed and describes a procedure for
determining an optimal configuration for the automatic PWM control.
Hardware Configurations
-----------------------
The ADT7473 chips have an optional SMBALERT output that can be used to
signal the chipset in case a limit is exceeded or the temperature sensors
fail. Individual sensor interrupts can be masked so they won't trigger
SMBALERT. The SMBALERT output if configured replaces the PWM2 function.
Configuration Notes
-------------------
Besides standard interfaces driver adds the following:
* PWM Control
* pwm#_auto_point1_pwm and pwm#_auto_point1_temp and
* pwm#_auto_point2_pwm and pwm#_auto_point2_temp -
point1: Set the pwm speed at a lower temperature bound.
point2: Set the pwm speed at a higher temperature bound.
The ADT7473 will scale the pwm between the lower and higher pwm speed when
the temperature is between the two temperature boundaries. PWM values range
from 0 (off) to 255 (full speed).
Notes
-----
The NVIDIA binary driver presents an ADT7473 chip via an on-card i2c bus.
Unfortunately, they fail to set the i2c adapter class, so this driver may
fail to find the chip until the nvidia driver is patched.

Real-Time group scheduling.
The problem space:
In order to schedule multiple groups of realtime tasks each group must
be assigned a fixed portion of the CPU time available. Without a minimum
guarantee a realtime group can obviously fall short. A fuzzy upper limit
is of no use since it cannot be relied upon. Which leaves us with just
the single fixed portion.
CPU time is divided by means of specifying how much time can be spent
running in a given period. Say a frame fixed realtime renderer must
deliver 25 frames a second, which yields a period of 0.04s. Now say
it will also have to play some music and respond to input, leaving it
with around 80% for the graphics. We can then give this group a runtime
of 0.8 * 0.04s = 0.032s.
This way the graphics group will have a 0.04s period with a 0.032s runtime
limit.
Now if the audio thread needs to refill the DMA buffer every 0.005s, but
needs only about 3% CPU time to do so, it can do with a 0.03 * 0.005s
= 0.00015s.
The Interface:
system wide:
/proc/sys/kernel/sched_rt_period_ms
/proc/sys/kernel/sched_rt_runtime_us
CONFIG_FAIR_USER_SCHED
/sys/kernel/uids/<uid>/cpu_rt_runtime_us
or
CONFIG_FAIR_CGROUP_SCHED
/cgroup/<cgroup>/cpu.rt_runtime_us
[ time is specified in us because the interface is s32; this gives an
operating range of ~35m to 1us ]
The period takes values in [ 1, INT_MAX ], runtime in [ -1, INT_MAX - 1 ].
A runtime of -1 specifies runtime == period, ie. no limit.
New groups get the period from /proc/sys/kernel/sched_rt_period_us and
a runtime of 0.
Settings are constrained to:
\Sum_{i} runtime_{i} / global_period <= global_runtime / global_period
in order to keep the configuration schedulable.
