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.

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.

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.

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.

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 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 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.

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 - * - * ? What was the last sigval ? SNN (signal NN) - * - * bBB..BB Set baud rate to BB..BB OK or BNN, then sets - * baud rate - * - * All commands and responses are sent with a packet which includes a - * checksum. A packet consists of - * - * $#. - * - * where - * :: - * :: < two hex digits computed as modulo 256 sum of > - * - * When a packet is received, it is first acknowledged with either '+' or '-'. - * '+' indicates a successful transfer. '-' indicates a failed transfer. - * - * Example: - * - * Host: Reply: - * $m0,10#2a +$00010203040506070809101112131415#42 - * - * - * ============== - * MORE EXAMPLES: - * ============== - * - * 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 - * $ 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.

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.
