+Regulator Consumer Driver Interface
+===================================
+
+This text describes the regulator interface for consumer device drivers.
+Please see overview.txt for a description of the terms used in this text.
+
+
+1. Consumer Regulator Access (static & dynamic drivers)
+=======================================================
+
+A consumer driver can get access to it's supply regulator by calling :-
+
+regulator = regulator_get(dev, "Vcc");
+
+The consumer passes in it's struct device pointer and power supply ID. The core
+then finds the correct regulator by consulting a machine specific lookup table.
+If the lookup is successful then this call will return a pointer to the struct
+regulator that supplies this consumer.
+
+To release the regulator the consumer driver should call :-
+
+regulator_put(regulator);
+
+Consumers can be supplied by more than one regulator e.g. codec consumer with
+analog and digital supplies :-
+
+digital = regulator_get(dev, "Vcc"); /* digital core */
+analog = regulator_get(dev, "Avdd"); /* analog */
+
+The regulator access functions regulator_get() and regulator_put() will
+usually be called in your device drivers probe() and remove() respectively.
+
+
+2. Regulator Output Enable & Disable (static & dynamic drivers)
+====================================================================
+
+A consumer can enable it's power supply by calling:-
+
+int regulator_enable(regulator);
+
+NOTE: The supply may already be enabled before regulator_enabled() is called.
+This may happen if the consumer shares the regulator or the regulator has been
+previously enabled by bootloader or kernel board initialization code.
+
+A consumer can determine if a regulator is enabled by calling :-
+
+int regulator_is_enabled(regulator);
+
+This will return > zero when the regulator is enabled.
+
+
+A consumer can disable it's supply when no longer needed by calling :-
+
+int regulator_disable(regulator);
+
+NOTE: This may not disable the supply if it's shared with other consumers. The
+regulator will only be disabled when the enabled reference count is zero.
+
+Finally, a regulator can be forcefully disabled in the case of an emergency :-
+
+int regulator_force_disable(regulator);
+
+NOTE: this will immediately and forcefully shutdown the regulator output. All
+consumers will be powered off.
+
+
+3. Regulator Voltage Control & Status (dynamic drivers)
+======================================================
+
+Some consumer drivers need to be able to dynamically change their supply
+voltage to match system operating points. e.g. CPUfreq drivers can scale
+voltage along with frequency to save power, SD drivers may need to select the
+correct card voltage, etc.
+
+Consumers can control their supply voltage by calling :-
+
+int regulator_set_voltage(regulator, min_uV, max_uV);
+
+Where min_uV and max_uV are the minimum and maximum acceptable voltages in
+microvolts.
+
+NOTE: this can be called when the regulator is enabled or disabled. If called
+when enabled, then the voltage changes instantly, otherwise the voltage
+configuration changes and the voltage is physically set when the regulator is
+next enabled.
+
+The regulators configured voltage output can be found by calling :-
+
+int regulator_get_voltage(regulator);
+
+NOTE: get_voltage() will return the configured output voltage whether the
+regulator is enabled or disabled and should NOT be used to determine regulator
+output state. However this can be used in conjunction with is_enabled() to
+determine the regulator physical output voltage.
+
+
+4. Regulator Current Limit Control & Status (dynamic drivers)
+===========================================================
+
+Some consumer drivers need to be able to dynamically change their supply
+current limit to match system operating points. e.g. LCD backlight driver can
+change the current limit to vary the backlight brightness, USB drivers may want
+to set the limit to 500mA when supplying power.
+
+Consumers can control their supply current limit by calling :-
+
+int regulator_set_current_limit(regulator, min_uV, max_uV);
+
+Where min_uA and max_uA are the minimum and maximum acceptable current limit in
+microamps.
+
+NOTE: this can be called when the regulator is enabled or disabled. If called
+when enabled, then the current limit changes instantly, otherwise the current
+limit configuration changes and the current limit is physically set when the
+regulator is next enabled.
+
+A regulators current limit can be found by calling :-
+
+int regulator_get_current_limit(regulator);
+
+NOTE: get_current_limit() will return the current limit whether the regulator
+is enabled or disabled and should not be used to determine regulator current
+load.
+
+
+5. Regulator Operating Mode Control & Status (dynamic drivers)
+=============================================================
+
+Some consumers can further save system power by changing the operating mode of
+their supply regulator to be more efficient when the consumers operating state
+changes. e.g. consumer driver is idle and subsequently draws less current
+
+Regulator operating mode can be changed indirectly or directly.
+
+Indirect operating mode control.
+--------------------------------
+Consumer drivers can request a change in their supply regulator operating mode
+by calling :-
+
+int regulator_set_optimum_mode(struct regulator *regulator, int load_uA);
+
+This will cause the core to recalculate the total load on the regulator (based
+on all it's consumers) and change operating mode (if necessary and permitted)
+to best match the current operating load.
+
+The load_uA value can be determined from the consumers datasheet. e.g.most
+datasheets have tables showing the max current consumed in certain situations.
+
+Most consumers will use indirect operating mode control since they have no
+knowledge of the regulator or whether the regulator is shared with other
+consumers.
+
+Direct operating mode control.
+------------------------------
+Bespoke or tightly coupled drivers may want to directly control regulator
+operating mode depending on their operating point. This can be achieved by
+calling :-
+
+int regulator_set_mode(struct regulator *regulator, unsigned int mode);
+unsigned int regulator_get_mode(struct regulator *regulator);
+
+Direct mode will only be used by consumers that *know* about the regulator and
+are not sharing the regulator with other consumers.
+
+
+6. Regulator Events
+===================
+Regulators can notify consumers of external events. Events could be received by
+consumers under regulator stress or failure conditions.
+
+Consumers can register interest in regulator events by calling :-
+
+int regulator_register_notifier(struct regulator *regulator,
+ struct notifier_block *nb);
+
+Consumers can uregister interest by calling :-
+
+int regulator_unregister_notifier(struct regulator *regulator,
+ struct notifier_block *nb);
+
+Regulators use the kernel notifier framework to send event to thier interested
+consumers.

+Regulator Machine Driver Interface
+===================================
+
+The regulator machine driver interface is intended for board/machine specific
+initialisation code to configure the regulator subsystem. Typical things that
+machine drivers would do are :-
+
+ 1. Regulator -> Device mapping.
+ 2. Regulator supply configuration.
+ 3. Power Domain constraint setting.
+
+
+
+1. Regulator -> device mapping
+==============================
+Consider the following machine :-
+
+ Regulator-1 -+-> Regulator-2 --> [Consumer A @ 1.8 - 2.0V]
+ |
+ +-> [Consumer B @ 3.3V]
+
+The drivers for consumers A & B must be mapped to the correct regulator in
+order to control their power supply. This mapping can be achieved in machine
+initialisation code by calling :-
+
+int regulator_set_device_supply(const char *regulator, struct device *dev,
+ const char *supply);
+
+and is shown with the following code :-
+
+regulator_set_device_supply("Regulator-1", devB, "Vcc");
+regulator_set_device_supply("Regulator-2", devA, "Vcc");
+
+This maps Regulator-1 to the 'Vcc' supply for Consumer B and maps Regulator-2
+to the 'Vcc' supply for Consumer A.
+
+
+2. Regulator supply configuration.
+==================================
+Consider the following machine (again) :-
+
+ Regulator-1 -+-> Regulator-2 --> [Consumer A @ 1.8 - 2.0V]
+ |
+ +-> [Consumer B @ 3.3V]
+
+Regulator-1 supplies power to Regulator-2. This relationship must be registered
+with the core so that Regulator-1 is also enabled when Consumer A enables it's
+supply (Regulator-2).
+
+This relationship can be register with the core via :-
+
+int regulator_set_supply(const char *regulator, const char *regulator_supply);
+
+In this example we would use the following code :-
+
+regulator_set_supply("Regulator-2", "Regulator-1");
+
+Relationships can be queried by calling :-
+
+const char *regulator_get_supply(const char *regulator);
+
+
+3. Power Domain constraint setting.
+===================================
+Each power domain within a system has physical constraints on voltage and
+current. This must be defined in software so that the power domain is always
+operated within specifications.
+
+Consider the following machine (again) :-
+
+ Regulator-1 -+-> Regulator-2 --> [Consumer A @ 1.8 - 2.0V]
+ |
+ +-> [Consumer B @ 3.3V]
+
+This gives us two regulators and two power domains:
+
+ Domain 1: Regulator-2, Consumer B.
+ Domain 2: Consumer A.
+
+Constraints can be registered by calling :-
+
+int regulator_set_platform_constraints(const char *regulator,
+ struct regulation_constraints *constraints);
+
+The example is defined as follows :-
+
+struct regulation_constraints domain_1 = {
+ .min_uV = 3300000,
+ .max_uV = 3300000,
+ .valid_modes_mask = REGULATOR_MODE_NORMAL,
+};
+
+struct regulation_constraints domain_2 = {
+ .min_uV = 1800000,
+ .max_uV = 2000000,
+ .valid_ops_mask = REGULATOR_CHANGE_VOLTAGE,
+ .valid_modes_mask = REGULATOR_MODE_NORMAL,
+};
+
+regulator_set_platform_constraints("Regulator-1", &domain_1);
+regulator_set_platform_constraints("Regulator-2", &domain_2);

+Linux voltage and current regulator framework
+=============================================
+
+About
+=====
+
+This framework is designed to provide a standard kernel interface to control
+voltage and current regulators.
+
+The intention is to allow systems to dynamically control regulator power output
+in order to save power and prolong battery life. This applies to both voltage
+regulators (where voltage output is controllable) and current sinks (where
+current limit is controllable).
+
+(C) 2008 Wolfson Microelectronics PLC.
+Author: Liam Girdwood <lg@opensource.wolfsonmicro.com>
+
+
+Nomenclature
+============
+
+Some terms used in this document:-
+
+ o Regulator - Electronic device that supplies power to other devices.
+ Most regulators can enable and disable their output whilst
+ some can control their output voltage and or current.
+
+ Input Voltage -> Regulator -> Output Voltage
+
+
+ o PMIC - Power Management IC. An IC that contains numerous regulators
+ and often contains other susbsystems.
+
+
+ o Consumer - Electronic device that is supplied power by a regulator.
+ Consumers can be classified into two types:-
+
+ Static: consumer does not change it's supply voltage or
+ current limit. It only needs to enable or disable it's
+ power supply. It's supply voltage is set by the hardware,
+ bootloader, firmware or kernel board initialisation code.
+
+ Dynamic: consumer needs to change it's supply voltage or
+ current limit to meet operation demands.
+
+
+ o Power Domain - Electronic circuit that is supplied it's input power by the
+ output power of a regulator, switch or by another power
+ domain.
+
+ The supply regulator may be behind a switch(s). i.e.
+
+ Regulator -+-> Switch-1 -+-> Switch-2 --> [Consumer A]
+ | |
+ | +-> [Consumer B], [Consumer C]
+ |
+ +-> [Consumer D], [Consumer E]
+
+ That is one regulator and three power domains:
+
+ Domain 1: Switch-1, Consumers D & E.
+ Domain 2: Switch-2, Consumers B & C.
+ Domain 3: Consumer A.
+
+ and this represents a "supplies" relationship:
+
+ Domain-1 --> Domain-2 --> Domain-3.
+
+ A power domain may have regulators that are supplied power
+ by other regulators. i.e.
+
+ Regulator-1 -+-> Regulator-2 -+-> [Consumer A]
+ |
+ +-> [Consumer B]
+
+ This gives us two regulators and two power domains:
+
+ Domain 1: Regulator-2, Consumer B.
+ Domain 2: Consumer A.
+
+ and a "supplies" relationship:
+
+ Domain-1 --> Domain-2
+
+
+ o Constraints - Constraints are used to define power levels for performance
+ and hardware protection. Constraints exist at three levels:
+
+ Regulator Level: This is defined by the regulator hardware
+ operating parameters and is specified in the regulator
+ datasheet. i.e.
+
+ - voltage output is in the range 800mV -> 3500mV.
+ - regulator current output limit is 20mA @ 5V but is
+ 10mA @ 10V.
+
+ Power Domain Level: This is defined in software by kernel
+ level board initialisation code. It is used to constrain a
+ power domain to a particular power range. i.e.
+
+ - Domain-1 voltage is 3300mV
+ - Domain-2 voltage is 1400mV -> 1600mV
+ - Domain-3 current limit is 0mA -> 20mA.
+
+ Consumer Level: This is defined by consumer drivers
+ dynamically setting voltage or current limit levels.
+
+ e.g. a consumer backlight driver asks for a current increase
+ from 5mA to 10mA to increase LCD illumination. This passes
+ to through the levels as follows :-
+
+ Consumer: need to increase LCD brightness. Lookup and
+ request next current mA value in brightness table (the
+ consumer driver could be used on several different
+ personalities based upon the same reference device).
+
+ Power Domain: is the new current limit within the domain
+ operating limits for this domain and system state (e.g.
+ battery power, USB power)
+
+ Regulator Domains: is the new current limit within the
+ regulator operating parameters for input/ouput voltage.
+
+ If the regulator request passes all the constraint tests
+ then the new regulator value is applied.
+
+
+Design
+======
+
+The framework is designed and targeted at SoC based devices but may also be
+relevant to non SoC devices and is split into the following four interfaces:-
+
+
+ 1. Consumer driver interface.
+
+ This uses a similar API to the kernel clock interface in that consumer
+ drivers can get and put a regulator (like they can with clocks atm) and
+ get/set voltage, current limit, mode, enable and disable. This should
+ allow consumers complete control over their supply voltage and current
+ limit. This also compiles out if not in use so drivers can be reused in
+ systems with no regulator based power control.
+
+ See Documentation/power/regulator/consumer.txt
+
+ 2. Regulator driver interface.
+
+ This allows regulator drivers to register their regulators and provide
+ operations to the core. It also has a notifier call chain for propagating
+ regulator events to clients.
+
+ See Documentation/power/regulator/regulator.txt
+
+ 3. Machine interface.
+
+ This interface is for machine specific code and allows the creation of
+ voltage/current domains (with constraints) for each regulator. It can
+ provide regulator constraints that will prevent device damage through
+ overvoltage or over current caused by buggy client drivers. It also
+ allows the creation of a regulator tree whereby some regulators are
+ supplied by others (similar to a clock tree).
+
+ See Documentation/power/regulator/machine.txt
+
+ 4. Userspace ABI.
+
+ The framework also exports a lot of useful voltage/current/opmode data to
+ userspace via sysfs. This could be used to help monitor device power
+ consumption and status.
+
+ See Documentation/ABI/testing/regulator-sysfs.txt

+Regulator Driver Interface
+==========================
+
+The regulator driver interface is relatively simple and designed to allow
+regulator drivers to register their services with the core framework.
+
+
+Registration
+============
+
+Drivers can register a regulator by calling :-
+
+struct regulator_dev *regulator_register(struct regulator_desc *regulator_desc,
+ void *reg_data);
+
+This will register the regulators capabilities and operations the regulator
+core. The core does not touch reg_data (private to regulator driver).
+
+Regulators can be unregistered by calling :-
+
+void regulator_unregister(struct regulator_dev *rdev);
+
+
+Regulator Events
+================
+Regulators can send events (e.g. over temp, under voltage, etc) to consumer
+drivers by calling :-
+
+int regulator_notifier_call_chain(struct regulator_dev *rdev,
+ unsigned long event, void *data);

- * EST SBC8260 Linux memory mapping rules
-
- http://www.estc.com/
- http://www.estc.com/products/boards/SBC8260-8240_ds.html
-
- Initial conditions:
- -------------------
-
- Tasks that need to be perform by the boot ROM before control is
- transferred to zImage (compressed Linux kernel):
-
- - Define the IMMR to 0xf0000000
-
- - Initialize the memory controller so that RAM is available at
- physical address 0x00000000. On the SBC8260 is this 16M (64M)
- SDRAM.
-
- - The boot ROM should only clear the RAM that it is using.
-
- The reason for doing this is to enhances the chances of a
- successful post mortem on a Linux panic. One of the first
- items to examine is the 16k (LOG_BUF_LEN) circular console
- buffer called log_buf which is defined in kernel/printk.c.
-
- - To enhance boot ROM performance, the I-cache can be enabled.
-
- Date: Mon, 22 May 2000 14:21:10 -0700
- From: Neil Russell <caret@c-side.com>
-
- LiMon (LInux MONitor) runs with and starts Linux with MMU
- off, I-cache enabled, D-cache disabled. The I-cache doesn't
- need hints from the MMU to work correctly as the D-cache
- does. No D-cache means no special code to handle devices in
- the presence of cache (no snooping, etc). The use of the
- I-cache means that the monitor can run acceptably fast
- directly from ROM, rather than having to copy it to RAM.
-
- - Build the board information structure (see
- include/asm-ppc/est8260.h for its definition)
-
- - The compressed Linux kernel (zImage) contains a bootstrap loader
- that is position independent; you can load it into any RAM,
- ROM or FLASH memory address >= 0x00500000 (above 5 MB), or
- at its link address of 0x00400000 (4 MB).
-
- Note: If zImage is loaded at its link address of 0x00400000 (4 MB),
- then zImage will skip the step of moving itself to
- its link address.
-
- - Load R3 with the address of the board information structure
-
- - Transfer control to zImage
-
- - The Linux console port is SMC1, and the baud rate is controlled
- from the bi_baudrate field of the board information structure.
- On thing to keep in mind when picking the baud rate, is that
- there is no flow control on the SMC ports. I would stick
- with something safe and standard like 19200.
-
- On the EST SBC8260, the SMC1 port is on the COM1 connector of
- the board.
-
-
- EST SBC8260 defaults:
- ---------------------
-

- Memory Sel Bus Use
- --------------------- --- --- ----------------------------------
- 0x00000000-0x03FFFFFF CS2 60x (16M or 64M)/64M SDRAM

- 0xFE000000-0xFFFFFFFF CS0 60x 4M/16M flash (SIMM)
-
- Notes:
- ------
-
- - The chip selects can map 32K blocks and up (powers of 2)
-
- - The SDRAM machine can handled up to 128Mbytes per chip select
-
- - Linux uses the 60x bus memory (the SDRAM DIMM) for the
- communications buffers.
-
- - BATs can map 128K-256Mbytes each. There are four data BATs and
- four instruction BATs. Generally the data and instruction BATs
- are mapped the same.
-
- - The IMMR must be set above the kernel virtual memory addresses,
- which start at 0xC0000000. Otherwise, the kernel may crash as
- soon as you start any threads or processes due to VM collisions
- in the kernel or user process space.
-
-
- Details from Dan Malek <dan_malek@mvista.com> on 10/29/1999:
-
- The user application virtual space consumes the first 2 Gbytes
- (0x00000000 to 0x7FFFFFFF). The kernel virtual text starts at
- 0xC0000000, with data following. There is a "protection hole"
- between the end of kernel data and the start of the kernel
- dynamically allocated space, but this space is still within
- 0xCxxxxxxx.
-
- Obviously the kernel can't map any physical addresses 1:1 in
- these ranges.
-
-
- Details from Dan Malek <dan_malek@mvista.com> on 5/19/2000:
-
- During the early kernel initialization, the kernel virtual
- memory allocator is not operational. Prior to this KVM
- initialization, we choose to map virtual to physical addresses
- 1:1. That is, the kernel virtual address exactly matches the
- physical address on the bus. These mappings are typically done
- in arch/ppc/kernel/head.S, or arch/ppc/mm/init.c. Only
- absolutely necessary mappings should be done at this time, for
- example board control registers or a serial uart. Normal device
- driver initialization should map resources later when necessary.
-
- Although platform dependent, and certainly the case for embedded
- 8xx, traditionally memory is mapped at physical address zero,
- and I/O devices above physical address 0x80000000. The lowest
- and highest (above 0xf0000000) I/O addresses are traditionally
- used for devices or registers we need to map during kernel
- initialization and prior to KVM operation. For this reason,
- and since it followed prior PowerPC platform examples, I chose
- to map the embedded 8xx kernel to the 0xc0000000 virtual address.
- This way, we can enable the MMU to map the kernel for proper
- operation, and still map a few windows before the KVM is operational.
-
- On some systems, you could possibly run the kernel at the
- 0x80000000 or any other virtual address. It just depends upon
- mapping that must be done prior to KVM operational. You can never
- map devices or kernel spaces that overlap with the user virtual
- space. This is why default IMMR mapping used by most BDM tools
- won't work. They put the IMMR at something like 0x10000000 or
- 0x02000000 for example. You simply can't map these addresses early
- in the kernel, and continue proper system operation.
-
- The embedded 8xx/82xx kernel is mature enough that all you should
- need to do is map the IMMR someplace at or above 0xf0000000 and it
- should boot far enough to get serial console messages and KGDB
- connected on any platform. There are lots of other subtle memory
- management design features that you simply don't need to worry
- about. If you are changing functions related to MMU initialization,
- you are likely breaking things that are known to work and are
- heading down a path of disaster and frustration. Your changes
- should be to make the flexibility of the processor fit Linux,
- not force arbitrary and non-workable memory mappings into Linux.
-
- - You don't want to change KERNELLOAD or KERNELBASE, otherwise the
- virtual memory and MMU code will get confused.
-
- arch/ppc/Makefile:KERNELLOAD = 0xc0000000
-
- include/asm-ppc/page.h:#define PAGE_OFFSET 0xc0000000
- include/asm-ppc/page.h:#define KERNELBASE PAGE_OFFSET
-
- - RAM is at physical address 0x00000000, and gets mapped to
- virtual address 0xC0000000 for the kernel.
-
-
- Physical addresses used by the Linux kernel:
- --------------------------------------------
-
- 0x00000000-0x3FFFFFFF 1GB reserved for RAM
- 0xF0000000-0xF001FFFF 128K IMMR 64K used for dual port memory,
- 64K for 8260 registers
-
-
- Logical addresses used by the Linux kernel:
- -------------------------------------------
-
- 0xF0000000-0xFFFFFFFF 256M BAT0 (IMMR: dual port RAM, registers)
- 0xE0000000-0xEFFFFFFF 256M BAT1 (I/O space for custom boards)
- 0xC0000000-0xCFFFFFFF 256M BAT2 (RAM)
- 0xD0000000-0xDFFFFFFF 256M BAT3 (if RAM > 256MByte)

+to know the *real* current state of the hardware. This can happen often, but
+it does not do any polling, so it is not enough on hardware that is subject

+Therefore, calling rfkill_force_state() when a state change happens is
+mandatory when the device has a hardware rfkill line, or when something else
+like the firmware could cause its state to be changed without going through the
+rfkill class.
Some hardware provides events when its status changes. In these cases, it is
best for the driver to not provide a get_state hook, and instead register the
rfkill class *already* with the correct status, and keep it updated using
rfkill_force_state() when it gets an event from the hardware.
+rfkill_force_state() must be used on the device resume handlers to update the
+rfkill status, should there be any chance of the device status changing during
+the sleep.

There is no provision for a statically-allocated rfkill struct. You must
use rfkill_allocate() to allocate one.

- * To enable debugger support, two things need to happen. One, a
- * call to set_debug_traps() is necessary in order to allow any breakpoints
- * or error conditions to be properly intercepted and reported to gdb.
- * Two, a breakpoint needs to be generated to begin communication. This
- * is most easily accomplished by a call to breakpoint(). Breakpoint()
- * simulates a breakpoint by executing a BREAK instruction.
- *
- *
- * The following gdb commands are supported:
- *
- * command function Return value
- *
- * g return the value of the CPU registers hex data or ENN
- * G set the value of the CPU registers OK or ENN
- *
- * mAA..AA,LLLL Read LLLL bytes at address AA..AA hex data or ENN
- * MAA..AA,LLLL: Write LLLL bytes at address AA.AA OK or ENN
- *
- * c Resume at current address SNN ( signal NN)
- * cAA..AA Continue at address AA..AA SNN
- *
- * s Step one instruction SNN
- * sAA..AA Step one instruction from AA..AA SNN
- *
- * k kill

- * All commands and responses are sent with a packet which includes a
- * checksum. A packet consists of
- *
- * $<packet info>#<checksum>.
- *
- * where
- * <packet info> :: <characters representing the command or response>
- * <checksum> :: < two hex digits computed as modulo 256 sum of <packetinfo>>
- *
- * When a packet is received, it is first acknowledged with either '+' or '-'.
- * '+' indicates a successful transfer. '-' indicates a failed transfer.
- *
- * Example:
- *

- *
- * For reference -- the following are the steps that one
- * company took (RidgeRun Inc) to get remote gdb debugging
- * going. In this scenario the host machine was a PC and the
- * target platform was a Galileo EVB64120A MIPS evaluation
- * board.
- *
- * Step 1:
- * First download gdb-5.0.tar.gz from the internet.
- * and then build/install the package.
- *
- * Example:
- * $ tar zxf gdb-5.0.tar.gz
- * $ cd gdb-5.0
- * $ ./configure --target=mips-linux-elf
- * $ make
- * $ install
- * $ which mips-linux-elf-gdb
- * /usr/local/bin/mips-linux-elf-gdb
- *
- * Step 2:
- * Configure linux for remote debugging and build it.
- *
- * Example:
- * $ cd ~/linux
- * $ make menuconfig <go to "Kernel Hacking" and turn on remote debugging>
- * $ make
- *
- * Step 3:
- * Download the kernel to the remote target and start
- * the kernel running. It will promptly halt and wait
- * for the host gdb session to connect. It does this
- * since the "Kernel Hacking" option has defined
- * CONFIG_KGDB which in turn enables your calls
- * to:
- * set_debug_traps();
- * breakpoint();
- *
- * Step 4:
- * Start the gdb session on the host.
- *
- * Example:
- * $ mips-linux-elf-gdb vmlinux
- * (gdb) set remotebaud 115200
- * (gdb) target remote /dev/ttyS1
- * ...at this point you are connected to
- * the remote target and can use gdb
- * in the normal fasion. Setting
- * breakpoints, single stepping,
- * printing variables, etc.

- If you say yes here you get support for National Semiconductor LM75
- sensor chips and clones: Dallas Semiconductor DS75 and DS1775 (in
- 9-bit precision mode), and TelCom (now Microchip) TCN75.
-
- The DS75 and DS1775 in 10- to 12-bit precision modes will require
- a force module parameter. The driver will not handle the extra
- precision anyhow.
+ If you say yes here you get support for one common type of
+ temperature sensor chip, with models including:
+
+ - Dallas Semiconductor DS75 and DS1775
+ - Maxim MAX6625 and MAX6626
+ - Microchip MCP980x
+ - National Semiconductor LM75
+ - NXP's LM75A
+ - ST Microelectronics STDS75
+ - TelCom (now Microchip) TCN75
+ - Texas Instruments TMP100, TMP101, TMP75, TMP175, TMP275
+
+ This driver supports driver model based binding through board
+ specific I2C device tables.
+
+ It also supports the "legacy" style of driver binding. To use
+ that with some chips which don't replicate LM75 quirks exactly,
+ you may need the "force" module parameter.
This driver can also be built as a module. If so, the module
will be called lm75.

+ * GRU Chiplet:
+ * The GRU is a user addressible memory accelerator. It provides
+ * several forms of load, store, memset, bcopy instructions. In addition, it
+ * contains special instructions for AMOs, sending messages to message
+ * queues, etc.
+ *
+ * The GRU is an integral part of the node controller. It connects
+ * directly to the cpu socket. In its current implementation, there are 2
+ * GRU chiplets in the node controller on each blade (~node).
+ *
+ * The entire GRU memory space is fully coherent and cacheable by the cpus.
+ *
+ * Each GRU chiplet has a physical memory map that looks like the following:
+ *
+ * +-----------------+
+ * |/////////////////|
+ * |/////////////////|
+ * |/////////////////|
+ * |/////////////////|

+ * +-----------------+ | |
+ * | ...... | \ | |
+ * +-----------------+ \____________ +-------------+
+ * | context 1 |
+ * +-----------------+
+ * | context 0 |
+ * +-----------------+
+ *
+ * Each of the "contexts" is a chunk of memory that can be mmaped into user
+ * space. The context consists of 2 parts:
+ *
+ * - an instruction space that can be directly accessed by the user
+ * to issue GRU instructions and to check instruction status.
+ *
+ * - a data area that acts as normal RAM.
+ *
+ * User instructions contain virtual addresses of data to be accessed by the
+ * GRU. The GRU contains a TLB that is used to convert these user virtual
+ * addresses to physical addresses.
+ *
+ * The "system control" area of the GRU chiplet is used by the kernel driver
+ * to manage user contexts and to perform functions such as TLB dropin and
+ * purging.
+ *
+ * One context may be reserved for the kernel and used for cross-partition
+ * communication. The GRU will also be used to asynchronously zero out
+ * large blocks of memory (not currently implemented).
+ *
+ *
+ * Tables:
+ *
+ * VDATA-VMA Data - Holds a few parameters. Head of linked list of
+ * GTS tables for threads using the GSEG
+ * GTS - Gru Thread State - contains info for managing a GSEG context. A
+ * GTS is allocated for each thread accessing a
+ * GSEG.
+ * GTD - GRU Thread Data - contains shadow copy of GRU data when GSEG is
+ * not loaded into a GRU
+ * GMS - GRU Memory Struct - Used to manage TLB shootdowns. Tracks GRUs
+ * where a GSEG has been loaded. Similar to
+ * an mm_struct but for GRU.
+ *
+ * GS - GRU State - Used to manage the state of a GRU chiplet
+ * BS - Blade State - Used to manage state of all GRU chiplets
+ * on a blade
+ *
+ *
+ * Normal task tables for task using GRU.
+ * - 2 threads in process
+ * - 2 GSEGs open in process
+ * - GSEG1 is being used by both threads
+ * - GSEG2 is used only by thread 2
+ *

+ * gru_flush_tlb_range
+ *
+ * General purpose TLB invalidation function. This function scans every GRU in
+ * the ENTIRE system (partition) looking for GRUs where the specified MM has
+ * been accessed by the GRU. For each GRU found, the TLB must be invalidated OR
+ * the ASID invalidated. Invalidating an ASID causes a new ASID to be assigned
+ * on the next fault. This effectively flushes the ENTIRE TLB for the MM at the
+ * cost of (possibly) a large number of future TLBmisses.
+ *
+ * The current algorithm is optimized based on the following (somewhat true)
+ * assumptions:
+ * - GRU contexts are not loaded into a GRU unless a reference is made to
+ * the data segment or control block (this is true, not an assumption).
+ * If a DS/CB is referenced, the user will also issue instructions that
+ * cause TLBmisses. It is not necessary to optimize for the case where
+ * contexts are loaded but no instructions cause TLB misses. (I know
+ * this will happen but I'm not optimizing for it).
+ * - GRU instructions to invalidate TLB entries are SLOOOOWWW - normally
+ * a few usec but in unusual cases, it could be longer. Avoid if
+ * possible.
+ * - intrablade process migration between cpus is not frequent but is
+ * common.
+ * - a GRU context is not typically migrated to a different GRU on the
+ * blade because of intrablade migration
+ * - interblade migration is rare. Processes migrate their GRU context to
+ * the new blade.
+ * - if interblade migration occurs, migration back to the original blade
+ * is very very rare (ie., no optimization for this case)
+ * - most GRU instruction operate on a subset of the user REGIONS. Code
+ * & shared library regions are not likely targets of GRU instructions.
+ *
+ * To help improve the efficiency of TLB invalidation, the GMS data
+ * structure is maintained for EACH address space (MM struct). The GMS is
+ * also the structure that contains the pointer to the mmu callout
+ * functions. This structure is linked to the mm_struct for the address space
+ * using the mmu "register" function. The mmu interfaces are used to
+ * provide the callbacks for TLB invalidation. The GMS contains:
+ *
+ * - asid[maxgrus] array. ASIDs are assigned to a GRU when a context is
+ * loaded into the GRU.
+ * - asidmap[maxgrus]. bitmap to make it easier to find non-zero asids in
+ * the above array
+ * - ctxbitmap[maxgrus]. Indicates the contexts that are currently active
+ * in the GRU for the address space. This bitmap must be passed to the
+ * GRU to do an invalidate.
+ *
+ * The current algorithm for invalidating TLBs is:
+ * - scan the asidmap for GRUs where the context has been loaded, ie,
+ * asid is non-zero.
+ * - for each gru found:
+ * - if the ctxtmap is non-zero, there are active contexts in the
+ * GRU. TLB invalidate instructions must be issued to the GRU.
+ * - if the ctxtmap is zero, no context is active. Set the ASID to
+ * zero to force a full TLB invalidation. This is fast but will
+ * cause a lot of TLB misses if the context is reloaded onto the
+ * GRU

+ Generic Voltage and Current Regulator support.
+
+ This framework is designed to provide a generic interface to voltage
+ and current regulators within the Linux kernel. It's intended to
+ provide voltage and current control to client or consumer drivers and
+ also provide status information to user space applications through a
+ sysfs interface.
+
+ The intention is to allow systems to dynamically control regulator
+ output in order to save power and prolong battery life. This applies
+ to both voltage regulators (where voltage output is controllable) and
+ current sinks (where current output is controllable).
+
+ This framework safely compiles out if not selected so that client
+ drivers can still be used in systems with no software controllable
+ regulators.
+
+ If unsure, say no.
+

+ * idling. Regulator r has > 90% efficiency in NORMAL mode at loads > 100mA
+ * but this drops rapidly to 60% when below 100mA. Regulator r has > 90%

+ * Most drivers will only care about NORMAL. The modes below are generic and

+ * Mode Description
+ * FAST Regulator can handle fast changes in it's load.
+ * e.g. useful in CPU voltage & frequency scaling where
+ * load can quickly increase with CPU frequency increases.
+ *
+ * NORMAL Normal regulator power supply mode. Most drivers will
+ * use this mode.
+ *
+ * IDLE Regulator runs in a more efficient mode for light
+ * loads. Can be used for devices that have a low power
+ * requirement during periods of inactivity. This mode
+ * may be more noisy than NORMAL and may not be able
+ * to handle fast load switching.
+ *
+ * STANDBY Regulator runs in the most efficient mode for very
+ * light loads. Can be used by devices when they are
+ * in a sleep/standby state. This mode is likely to be
+ * the most noisy and may not be able to handle fast load
+ * switching.
+ *
+ * NOTE: Most regulators will only support a subset of these modes. Some
+ * will only just support NORMAL.
+ *
