+
+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.

+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

+
+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.

+/*
+ * Watchdog driver for SiByte SB1 SoCs
+ *
+ * Copyright (C) 2007 OnStor, Inc. * Andrew Sharp <andy.sharp@onstor.com>
+ *
+ * This driver is intended to make the second of two hardware watchdogs
+ * on the Sibyte 12XX and 11XX SoCs available to the user. There are two
+ * such devices available on the SoC, but it seems that there isn't an
+ * enumeration class for watchdogs in Linux like there is for RTCs.
+ * The second is used rather than the first because it uses IRQ 1,
+ * thereby avoiding all that IRQ 0 problematic nonsense.
+ *
+ * I have not tried this driver on a 1480 processor; it might work
+ * just well enough to really screw things up.
+ *
+ * It is a simple timer, and there is an interrupt that is raised the
+ * first time the timer expires. The second time it expires, the chip
+ * is reset and there is no way to redirect that NMI. Which could
+ * be problematic in some cases where this chip is sitting on the HT
+ * bus and has just taken responsibility for providing a cache block.
+ * Since the reset can't be redirected to the external reset pin, it is
+ * possible that other HT connected processors might hang and not reset.
+ * For Linux, a soft reset would probably be even worse than a hard reset.
+ * There you have it.
+ *
+ * The timer takes 23 bits of a 64 bit register (?) as a count value,
+ * and decrements the count every microsecond, for a max value of
+ * 0x7fffff usec or about 8.3ish seconds.
+ *
+ * This watchdog borrows some user semantics from the softdog driver,
+ * in that if you close the fd, it leaves the watchdog running, unless
+ * you previously wrote a 'V' to the fd, in which case it disables
+ * the watchdog when you close the fd like some other drivers.
+ *
+ * Based on various other watchdog drivers, which are probably all
+ * loosely based on something Alan Cox wrote years ago.

- * Instantiations of the elf_fpregset_t type contain, in most
- * architectures, the floating point (FPU) register set.
- * For Xtensa, this type is extended to contain all custom state,
- * ie. coprocessor and "extra" (non-coprocessor) state (including,
- * for example, TIE-defined states and register files; as well
- * as other optional processor state).
- * This includes FPU state if a floating-point coprocessor happens
- * to have been configured within the Xtensa processor.
- *
- * TOTAL_FPREGS_SIZE is the required size (without rounding)
- * of elf_fpregset_t. It provides space for the following:
- *
- * a) 32-bit mask of active coprocessors for this task (similar
- * to CPENABLE in single-threaded Xtensa processor systems)
- *
- * b) table describing the layout of custom states (ie. of
- * individual registers, etc) within the save areas
- *
- * c) save areas for each coprocessor and for non-coprocessor
- * ("extra") state
- *
- * Note that save areas may require up to 16-byte alignment when
- * accessed by save/restore sequences. We do not need to ensure
- * such alignment in an elf_fpregset_t structure because custom
- * state is not directly loaded/stored into it; rather, save area
- * contents are copied to elf_fpregset_t from the active save areas
- * (see 'struct task_struct' definition in processor.h for that)
- * using memcpy(). But we do allow space for such alignment,
- * to allow optimizations of layout and copying.
