The decompressor will zero initialise ++ this for you. Again, the MMU will be off. ++ ++ZRELADDR ++ This is the address where the decompressed kernel will be written, ++ and eventually executed.

During the kernel ++ boot phase, virtual address PAGE_OFFSET will be mapped to physical ++ address PHYS_OFFSET, along with any other mappings you supply. ++ This should be the same value as TASK_SIZE. ++ ++TASK_SIZE ++ The maximum size of a user process in bytes. Since user space ++ always starts at zero, this is the maximum address that a user ++ process can access+1. The user space stack grows down from this ++ address. ++ ++ Any virtual address below TASK_SIZE is deemed to be user process ++ area, and therefore managed dynamically on a process by process ++ basis by the kernel. I'll call this the user segment. ++ ++ Anything above TASK_SIZE is common to all processes. I'll call ++ this the kernel segment. ++ ++ (In other words, you can't put IO mappings below TASK_SIZE, and ++ hence PAGE_OFFSET). ++ ++TEXTADDR ++ Virtual start address of kernel, normally PAGE_OFFSET + 0x8000. ++ This is where the kernel image ends up. With the latest kernels, ++ it must be located at 32768 bytes into a 128MB region. Previous ++ kernels placed a restriction of 256MB here. ++ ++DATAADDR ++ Virtual address for the kernel data segment. Must not be defined ++ when using the decompressor. ++ ++VMALLOC_START ++VMALLOC_END ++ Virtual addresses bounding the vmalloc() area. There must not be ++ any static mappings in this area; vmalloc will overwrite them. ++ The addresses must also be in the kernel segment (see above). ++ Normally, the vmalloc() area starts VMALLOC_OFFSET bytes above the ++ last virtual RAM address (found using variable high_memory). ++ ++VMALLOC_OFFSET ++ Offset normally incorporated into VMALLOC_START to provide a hole ++ between virtual RAM and the vmalloc area.

CPUFreq notifiers ++ ++1. General Information ++======================= ++ ++The CPUFreq core code is located in linux/kernel/cpufreq.c. This ++cpufreq code offers a standardized interface for the CPUFreq ++architecture drivers (those pieces of code that do actual ++frequency transitions), as well as to "notifiers". These are device ++drivers or other part of the kernel that need to be informed of ++policy changes (ex. thermal modules like ACPI) or of all ++frequency changes (ex. timing code) or even need to force certain ++speed limits (like LCD drivers on ARM architecture). Additionally, the ++kernel "constant" loops_per_jiffy is updated on frequency changes ++here. ++ ++Reference counting is done by cpufreq_get_cpu and cpufreq_put_cpu, ++which make sure that the cpufreq processor driver is correctly ++registered with the core, and will not be unloaded until ++cpufreq_put_cpu is called. ++ ++2. CPUFreq notifiers ++==================== ++ ++CPUFreq notifiers conform to the standard kernel notifier interface. ++See linux/include/linux/notifier.h for details on notifiers. ++ ++There are two different CPUFreq notifiers - policy notifiers and ++transition notifiers. ++ ++ ++2.1 CPUFreq policy notifiers ++---------------------------- ++ ++These are notified when a new policy is intended to be set. Each ++CPUFreq policy notifier is called three times for a policy transition: ++ ++1.) During CPUFREQ_ADJUST all CPUFreq notifiers may change the limit if ++ they see a need for this - may it be thermal considerations or ++ hardware limitations. ++ ++2.) During CPUFREQ_INCOMPATIBLE only changes may be done in order to avoid ++ hardware failure. ++ ++3.) And during CPUFREQ_NOTIFY all notifiers are informed of the new policy ++ - if two hardware drivers failed to agree on a new policy before this ++ stage, the incompatible hardware shall be shut down, and the user ++ informed of this. ++ ++The phase is specified in the second argument to the notifier. ++ ++The third argument, a void *pointer, points to a struct cpufreq_policy ++consisting of five values: cpu, min, max, policy and max_cpu_freq. min ++and max are the lower and upper frequencies (in kHz) of the new ++policy, policy the new policy, cpu the number of the affected CPU or ++CPUFREQ_ALL_CPUS for all CPUs; and max_cpu_freq the maximum supported ++CPU frequency. This value is given for informational purposes only. ++ ++ ++2.2 CPUFreq transition notifiers ++-------------------------------- ++ ++These are notified twice when the CPUfreq driver switches the CPU core ++frequency and this change has any external implications. ++ ++The second argument specifies the phase - CPUFREQ_PRECHANGE or ++CPUFREQ_POSTCHANGE. ++ ++The third argument is a struct cpufreq_freqs with the following ++values: ++cpu - number of the affected CPU or CPUFREQ_ALL_CPUS ++old - old frequency ++new - new frequency +diff -urN linux-2.4.26/Documentation/cpufreq/cpu-drivers.txt linux-2.4.26-vrs1/Documentation/cpufreq/cpu-drivers.txt +--- linux-2.4.26/Documentation/cpufreq/cpu-drivers.txt 1970-01-01 01:00:00.000000000 +0100 ++++ linux-2.4.26-vrs1/Documentation/cpufreq/cpu-drivers.txt 2004-01-14 21:32:23.000000000 +0000 +@@ -0,0 +1,210 @@ ++ CPU frequency and voltage scaling code in the Linux(TM) kernel ++ ++ ++ L i n u x C P U F r e q ++ ++ C P U D r i v e r s ++ ++ - information for developers - ++ ++ ++ Dominik Brodowski ++ ++ ++ ++ Clock scaling allows you to change the clock speed of the CPUs on the ++ fly.

What To Do? ++============== ++ ++So, you just got a brand-new CPU / chipset with datasheets and want to ++add cpufreq support for this CPU / chipset? Great. Here are some hints ++on what is neccessary: ++ ++ ++1.1 Initialization ++------------------ ++ ++First of all, in an __initcall level 7 or later (preferrably ++module_init() so that your driver is modularized) function check ++whether this kernel runs on the right CPU and the right chipset. If ++so, register a struct cpufreq_driver with the CPUfreq core using ++cpufreq_register_driver() ++ ++What shall this struct cpufreq_driver contain? ++ ++cpufreq_driver.name - The name of this driver. ++ ++cpufreq_driver.init - A pointer to the per-CPU initialization ++ function. ++ ++cpufreq_driver.verify - A pointer to a "verfication" funciton. ++ ++cpufreq_driver.setpolicy _or_ ++cpufreq_driver.target - See below on the differences. ++ ++And optionally ++ ++cpufreq_driver.exit - A pointer to a per-CPU cleanup function. ++ ++cpufreq_driver.attr - A pointer to a NULL-terminated list of ++ "struct freq_attr" which allow to ++ export values to sysfs. ++ ++ ++1.2 Per-CPU Initialization ++-------------------------- ++ ++Whenever a new CPU is registered with the device model, or after the ++cpufreq driver registers itself, the per-CPU initialization fucntion ++cpufreq_driver.init is called. It takes a struct cpufreq_policy ++*policy as argument. What to do now? ++ ++If necessary, activate the CPUfreq support on your CPU (unlock that ++register etc.). ++ ++Then, the driver must fill in the following values: ++ ++policy->cpuinfo.min_freq _and_ ++policy->cpuinfo.max_freq - the minimum and maximum frequency ++ (in kHz) which is supported by ++ this CPU ++policy->cpuinfo.transition_latency the time it takes on this CPU to ++ switch between two frequencies (if ++ appropriate, else specify ++ CPUFREQ_ETERNAL) ++ ++policy->cur The current operating frequency of ++ this CPU (if appropriate) ++policy->min, ++policy->max, ++policy->policy and, if neccessary, ++policy->governor must contain the "default policy" for ++ this CPU. A few moments later, ++ cpufreq_driver.verify and either ++ cpufreq_driver.setpolicy or ++ cpufreq_driver.target is called with ++ these values. ++ ++For setting some of these values, the frequency table helpers might be ++helpful. See the section 2 for more information on them. ++ ++ ++1.3 verify ++------------ ++ ++When the user decides a new policy (consisting of ++"policy,governor,min,max") shall be set, this policy must be validated ++so that incompatible values can be corrected. For verifying these ++values, a frequency table helper and/or the ++cpufreq_verify_within_limits(struct cpufreq_policy *policy, unsigned ++int min_freq, unsigned int max_freq) function might be helpful. See ++section 2 for details on frequency table helpers. ++ ++You need to make sure that at least one valid frequency (or operating ++range) is within policy->min and policy->max. If necessary, increase ++policy->max fist, and only if this is no solution, decreas policy->min. ++ ++ ++1.4 target or setpolicy? ++---------------------------- ++ ++Most cpufreq drivers or even most cpu frequency scaling algorithms ++only allow the CPU to be set to one frequency. For these, you use the ++->target call. ++ ++Some cpufreq-capable processors switch the frequency between certain ++limits on their own. These shall use the ->setpolicy call ++ ++ ++1.4. target ++------------- ++ ++The target call has three arguments: struct cpufreq_policy *policy, ++unsigned int target_frequency, unsigned int relation. ++ ++The CPUfreq driver must set the new frequency when called here. The ++actual frequency must be determined using the following rules: ++ ++- keep close to "target_freq" ++- policy->min <= new_freq <= policy->max (THIS MUST BE VALID!!!) ++- if relation==CPUFREQ_REL_L, try to select a new_freq higher than or equal ++ target_freq. ("L for lowest, but no lower than") ++- if relation==CPUFREQ_REL_H, try to select a new_freq lower than or equal ++ target_freq. ("H for highest, but no higher than") ++ ++Here again the frequency table helper might assist you - see section 3 ++for details. ++ ++ ++1.5 setpolicy ++--------------- ++ ++The setpolicy call only takes a struct cpufreq_policy *policy as ++argument. You need to set the lower limit of the in-processor or ++in-chipset dynamic frequency switching to policy->min, the upper limit ++to policy->max, and -if supported- select a performance-oriented ++setting when policy->policy is CPUFREQ_POLICY_PERFORMANCE, and a ++powersaving-oriented setting when CPUFREQ_POLICY_POWERSAVE. Also check ++the reference implementation in arch/i386/kernel/cpu/cpufreq/longrun.c ++ ++ ++ ++2. Frequency Table Helpers ++========================== ++ ++As most cpufreq processors only allow for being set to a few specific ++frequencies, a "frequency table" with some functions might assist in ++some work of the processor driver. Such a "frequency table" consists ++of an array of struct cpufreq_freq_table entries, with any value in ++"index" you want to use, and the corresponding frequency in ++"frequency". At the end of the table, you need to add a ++cpufreq_freq_table entry with frequency set to CPUFREQ_TABLE_END. And ++if you want to skip one entry in the table, set the frequency to ++CPUFREQ_ENTRY_INVALID. The entries don't need to be in ascending ++order. ++ ++By calling cpufreq_frequency_table_cpuinfo(struct cpufreq_policy *policy, ++ struct cpufreq_frequency_table *table); ++the cpuinfo.min_freq and cpuinfo.max_freq values are detected, and ++policy->min and policy->max are set to the same values. This is ++helpful for the per-CPU initialization stage. ++ ++int cpufreq_frequency_table_verify(struct cpufreq_policy *policy, ++ struct cpufreq_frequency_table *table); ++assures that at least one valid frequency is within policy->min and ++policy->max, and all other criteria are met. This is helpful for the ++->verify call. ++ ++int cpufreq_frequency_table_target(struct cpufreq_policy *policy, ++ struct cpufreq_frequency_table *table, ++ unsigned int target_freq, ++ unsigned int relation, ++ unsigned int *index); ++ ++is the corresponding frequency table helper for the ->target ++stage. Just pass the values to this function, and the unsigned int ++index returns the number of the frequency table entry which contains ++the frequency the CPU shall be set to. PLEASE NOTE: This is not the ++"index" which is in this cpufreq_table_entry.index, but instead ++cpufreq_table[index]. So, the new frequency is ++cpufreq_table[index].frequency, and the value you stored into the ++frequency table "index" field is ++cpufreq_table[index].index. ++ +diff -urN linux-2.4.26/Documentation/cpufreq/governors.txt linux-2.4.26-vrs1/Documentation/cpufreq/governors.txt +--- linux-2.4.26/Documentation/cpufreq/governors.txt 1970-01-01 01:00:00.000000000 +0100 ++++ linux-2.4.26-vrs1/Documentation/cpufreq/governors.txt 2004-01-14 21:32:23.000000000 +0000 +@@ -0,0 +1,155 @@ ++ CPU frequency and voltage scaling code in the Linux(TM) kernel ++ ++ ++ L i n u x C P U F r e q ++ ++ C P U F r e q G o v e r n o r s ++ ++ - information for users and developers - ++ ++ ++ Dominik Brodowski ++ ++ ++ ++ Clock scaling allows you to change the clock speed of the CPUs on the ++ fly.

Governors In the Linux Kernel ++2.1 Performance ++2.2 Powersave ++2.3 Userspace ++ ++3. The Governor Interface in the CPUfreq Core ++ ++ ++ ++1. What Is A CPUFreq Governor? ++============================== ++ ++Most cpufreq drivers (in fact, all except one, longrun) or even most ++cpu frequency scaling algorithms only offer the CPU to be set to one ++frequency. In order to offer dynamic frequency scaling, the cpufreq ++core must be able to tell these drivers of a "target frequency". So ++these specific drivers will be transformed to offer a "->target" ++call instead of the existing "->setpolicy" call. For "longrun", all ++stays the same, though. ++ ++How to decide what frequency within the CPUfreq policy should be used? ++That's done using "cpufreq governors". Two are already in this patch ++-- they're the already existing "powersave" and "performance" which ++set the frequency statically to the lowest or highest frequency, ++respectively. At least two more such governors will be ready for ++addition in the near future, but likely many more as there are various ++different theories and models about dynamic frequency scaling ++around. Using such a generic interface as cpufreq offers to scaling ++governors, these can be tested extensively, and the best one can be ++selected for each specific use. ++ ++Basically, it's the following flow graph: ++ ++CPU can be set to switch independetly | CPU can only be set ++ within specific "limits" | to specific frequencies ++ ++ "CPUfreq policy" ++ consists of frequency limits (policy->{min,max}) ++ and CPUfreq governor to be used ++ / \ ++ / \ ++ / the cpufreq governor decides ++ / (dynamically or statically) ++ / what target_freq to set within ++ / the limits of policy->{min,max} ++ / \ ++ / \ ++ Using the ->setpolicy call, Using the ->target call, ++ the limits and the the frequency closest ++ "policy" is set. to target_freq is set. ++ It is assured that it ++ is within policy->{min,max} ++ ++ ++2. Governors In the Linux Kernel ++================================ ++ ++2.1 Performance ++--------------- ++ ++The CPUfreq governor "performance" sets the CPU statically to the ++highest frequency within the borders of scaling_min_freq and ++scaling_max_freq. ++ ++ ++2.1 Powersave ++------------- ++ ++The CPUfreq governor "powersave" sets the CPU statically to the ++lowest frequency within the borders of scaling_min_freq and ++scaling_max_freq. ++ ++ ++2.2 Userspace ++------------- ++ ++The CPUfreq governor "userspace" allows the user, or any userspace ++program running with UID "root", to set the CPU to a specifc frequency ++by making a sysfs file "scaling_setspeed" available in the CPU-device ++directory. ++ ++ ++ ++3. The Governor Interface in the CPUfreq Core ++============================================= ++ ++A new governor must register itself with the CPUfreq core using ++"cpufreq_register_governor". The struct cpufreq_governor, which has to ++be passed to that function, must contain the following values: ++ ++governor->name - A unique name for this governor ++governor->governor - The governor callback function ++governor->owner - .THIS_MODULE for the governor module (if ++ appropriate) ++ ++The governor->governor callback is called with the current (or to-be-set) ++cpufreq_policy struct for that CPU, and an unsigned int event. The ++following events are currently defined: ++ ++CPUFREQ_GOV_START: This governor shall start its duty for the CPU ++ policy->cpu ++CPUFREQ_GOV_STOP: This governor shall end its duty for the CPU ++ policy->cpu ++CPUFREQ_GOV_LIMITS: The limits for CPU policy->cpu have changed to ++ policy->min and policy->max. ++ ++If you need other "events" externally of your driver, _only_ use the ++cpufreq_governor_l(unsigned int cpu, unsigned int event) call to the ++CPUfreq core to ensure proper locking. ++ ++ ++The CPUfreq governor may call the CPU processor driver using one of ++these two functions: ++ ++inline int cpufreq_driver_target(struct cpufreq_policy *policy, ++ unsigned int target_freq, ++ unsigned int relation); ++ ++inline int cpufreq_driver_target_l(struct cpufreq_policy *policy, ++ unsigned int target_freq, ++ unsigned int relation); ++ ++target_freq must be within policy->min and policy->max, of course. ++What's the difference between these two functions? When your governor ++still is in a direct code path of a call to governor->governor, the ++cpufreq_driver_sem lock is still held in the cpufreq core, and there's ++no need to lock it again (in fact, this would cause a deadlock). So ++use cpufreq_driver_target only in these cases. In all other cases (for ++example, when there's a "daemonized" function that wakes up every ++second), use cpufreq_driver_target_l to lock the cpufreq_driver_sem ++before the command is passed to the cpufreq processor driver. ++ +diff -urN linux-2.4.26/Documentation/cpufreq/index.txt linux-2.4.26-vrs1/Documentation/cpufreq/index.txt +--- linux-2.4.26/Documentation/cpufreq/index.txt 1970-01-01 01:00:00.000000000 +0100 ++++ linux-2.4.26-vrs1/Documentation/cpufreq/index.txt 2004-01-14 21:32:23.000000000 +0000 +@@ -0,0 +1,56 @@ ++ CPU frequency and voltage scaling code in the Linux(TM) kernel ++ ++ ++ L i n u x C P U F r e q ++ ++ ++ ++ ++ Dominik Brodowski ++ ++ ++ ++ Clock scaling allows you to change the clock speed of the CPUs on the ++ fly.

"Policy" / "Governor" ? ++========================== ++ ++Some CPU frequency scaling-capable processor switch between varios ++frequencies and operating voltages "on the fly" without any kernel or ++user involvement. This guarantuees very fast switching to a frequency ++which is high enough to serve the user's needs, but low enough to save ++power. ++ ++ ++2.1 Policy ++---------- ++ ++On these systems, all you can do is select the lower and upper ++frequency limit as well as whether you want more aggressive ++power-saving or more instantly avaialble processing power. ++ ++ ++2.2 Governor ++------------ ++ ++On all other cpufreq implementations, these boundaries still need to ++be set. Then, a "governor" must be selected. Such a "governor" decides ++what speed the processor shall run within the boundaries. One such ++"governor" is the "userspace" governor. This one allows the user - or ++a yet-to-implement userspace program - to decide what specific speed ++the processor shall run at. ++ ++ ++3. How to change the CPU cpufreq policy and/or speed ++==================================================== ++ ++3.1 Preferred Interface: sysfs ++------------------------------ ++ ++The preferred interface is located in the sysfs filesystem. If you ++mounted it at /sys, the cpufreq interface is located in a subdirectory ++"cpufreq" within the cpu-device directory ++(e.g. /sys/devices/sys/cpu0/cpufreq/ for the first CPU). ++ ++cpuinfo_min_freq : this file shows the minimum operating ++ frequency the processor can run at(in kHz) ++cpuinfo_max_freq : this file shows the maximum operating ++ frequency the processor can run at(in kHz) ++scaling_driver : this file shows what cpufreq driver is ++ used to set the frequency on this CPU ++ ++scaling_available_governors : this file shows the CPUfreq governors ++ available in this kernel. You can see the ++ currently activated governor in ++ ++scaling_governor, and by "echoing" the name of another ++ governor you can change it. Please note ++ that some governors won't load - they only ++ work on some specific architectures or ++ processors. ++scaling_min_freq and ++scaling_max_freq show the current "policy limits" (in ++ kHz). By echoing new values into these ++ files, you can change these limits. ++ ++ ++If you have selected the "userspace" governor which allows you to ++set the CPU operating frequency to a specific value, you can read out ++the current frequency in ++ ++scaling_setspeed. By "echoing" a new frequency into this ++ you can change the speed of the CPU, ++ but only within the limits of ++ scaling_min_freq and scaling_max_freq. ++ ++ ++3.2 Deprecated Interfaces ++------------------------- ++ ++Depending on your kernel configuration, you might find the following ++cpufreq-related files: ++/proc/cpufreq ++/proc/sys/cpu/*/speed ++/proc/sys/cpu/*/speed-min ++/proc/sys/cpu/*/speed-max ++ ++These are files for deprecated interfaces to cpufreq, which offer far ++less functionality.

Supported architectures ++========================== ++ ++Some architectures detect the lowest and highest possible speed ++settings, while others rely on user information on this. For the ++latter, a boot parameter is required, for the former, you can specify ++one to set the limits between speed settings may occur. ++The boot parameter has the following syntax: ++ ++ cpufreq=minspeed-maxspeed ++ ++with both minspeed and maxspeed being given in kHz. To set the lower ++limit to 59 MHz and the upper limit to 221 MHz, specify: ++ ++ cpufreq=59000-221000 ++ ++Check the "Speed Limits Detection" information below on whether ++the driver detects the lowest and highest allowed speed setting ++automatically. ++ ++ ++ARM Integrator: ++ SA 1100, SA1110 ++-------------------------------- ++ Speed Limits Detection: On Integrators, the minimum speed is set ++ and the maximum speed has to be specified using the boot ++ parameter.

User Interface ++================= ++ ++CPUFreq uses a "sysctl" interface which is located in ++ /proc/sys/cpu/0/ on UP (uniprocessor) kernels, or ++ /proc/sys/cpu/any/ on SMP (symmetric multiprocessoring) kernels. ++ ++ ++In this directory, you will find three files of importance for ++CPUFreq: speed-max, speed-min, and speed: ++ ++speed shows the current CPU frequency in kHz, ++speed-min the minimal supported CPU frequency, and ++speed-max the maximal supported CPU frequency. ++ ++Please note that you might have to specify these limits as a boot ++parameter depending on the architecture (see above). ++ ++ ++To change the CPU frequency, "echo" the desired CPU frequency (in kHz) ++to speed. For example, to set the CPU speed to the lowest/highest ++allowed frequency do: ++ ++root@notebook:# cat /proc/sys/cpu/0/speed-min > /proc/sys/cpu/0/speed ++root@notebook:# cat /proc/sys/cpu/0/speed-max > /proc/sys/cpu/0/speed ++ ++ ++2.1 Sample script for command line interface ++********************************************** ++ ++ ++Michael Ossmann has written a small command line ++interface for the infinitely lazy. ++ ++#!/bin/bash ++# ++# /usr/local/bin/freq ++# simple command line interface to cpufreq ++ ++[ -n "$1" ] && case "$1" in ++ "min" ) ++ # set frequency to minimum ++ cat /proc/sys/cpu/0/speed-min >/proc/sys/cpu/0/speed ++ ;; ++ "max" ) ++ # set frequency to maximum ++ cat /proc/sys/cpu/0/speed-max >/proc/sys/cpu/0/speed ++ ;; ++ * ) ++ echo "Usage: $0 [min|max]" ++ echo " min: set frequency to minimum and display new frequency" ++ echo " max: set frequency to maximum and display new frequency" ++ echo " no options: display current frequency" ++ exit 1 ++ ;; ++esac ++ ++# display current frequency ++cat /proc/sys/cpu/0/speed ++exit 0 ++ ++ ++ ++3. CPUFreq core and interfaces ++=============================== ++ ++3.1 General information ++************************* ++ ++The CPUFreq core code is located in linux/kernel/cpufreq.c. This ++cpufreq code offers a standardized interface for the CPUFreq ++architecture drivers (those pieces of code that do the actual ++frequency transition), as well as to "notifiers". These are device ++drivers or other part of the kernel that need to be informed of ++frequency changes (like timing code) or even need to force certain ++speed limits (like LCD drivers on ARM architecture). Aditionally, the ++kernel "constant" loops_per_jiffy is updated on frequency changes ++here. ++ ++ ++3.2 CPUFreq notifiers ++*********************** ++ ++CPUFreq notifiers are kernel code that need to be called to either ++a) define certain minimum or maximum speed settings, ++b) be informed of frequency changes in advance of the transition, or ++c) be informed of frequency changes directly after the transition. ++ ++A standard kernel notifier interface is offered for this. See ++linux/include/linux/notifier.h for details on notifiers. ++ ++ ++Data and value passed to CPUFreq notifiers ++------------------------------------------ ++The second argument passed to any notifier is an unsigned int stating ++the phase of the transition: ++CPUFREQ_MINMAX during the process of determing a valid new CPU ++ frequency, ++CPUFREQ_PRECHANGE right before the transition, and ++CPUFREQ_POSTCHANGE right after the transition. ++ ++The third argument, a void *pointer, points to a struct ++cpufreq_freqs. This consists of four values: min, max, cur and new. ++ ++min and max are the current speed limits. Please note: Never update ++these values directly, use cpufreq_updateminmax(struct cpufreq_freqs ++*freqs, unsigned int min, unsigned int max) instead. cur is the ++current/old speed, and new is the new speed, but might only be valid ++on CPUFREQ_PRECHANGE or CPUFREQ_POSTCHANGE. ++ ++Each notifier gets called all three times on any transition: ++ ++CPUFREQ_MINMAX ++Here the notifier is supposed to update the min and max values to the ++limits the protected device / kernel code needs. As stated above, ++always use cpufreq_updateminmax for this. ++ ++CPUFREQ_PRECHANGE ++CPUFREQ_POSTCHANGE ++Here the notifier is supposed to update all internal (e.g. device ++driver) code which is dependend on the CPU frequency. ++ ++ ++3.3 CPUFreq architecture drivers ++********************************** ++ ++CPUFreq architecture drivers are the pieces of kernel code that ++actually perform CPU frequency transitions. These need to be ++initialised seperately (seperate initcalls), and may be ++modularized. They interact with the CPUFreq core in the following way: ++ ++ ++cpufreq_register() ++------------------ ++cpufreq_register registers an arch driver to the CPUFreq core. Please ++note that only one arch driver may be registered at any time, -EBUSY ++is returned when an arch driver is already registered. The argument to ++cpufreq_register, cpufreq_driver_t driver, is described later. ++ ++ ++cpufreq_unregister() ++-------------------- ++cpufreq_unregister unregisters an arch driver, e.g. on module ++unloading. Please note that there is no check done that this is called ++from the driver which actually registered itself to the core, so ++please only call this function when you are sure the arch driver got ++registered correctly before. ++ ++ ++struct cpufreq_driver ++---------------- ++On initialisation, the arch driver is supposed to pass the following ++entries in struct cpufreq_driver cpufreq_driver: ++ ++cpufreq_verify_t validate: This is a pointer to a function with the ++following definition: ++ unsigned int validating_function (unsigned int kHz). ++It is called right before a transition occurs. The proposed new ++speed setting is passed as an argument in kHz; the validating code ++should verify this is a valid speed setting which is currently ++supported by the CPU. It shall return the closest valid CPU frequency ++in kHz. ++ ++cpufreq_setspeed_t setspeed: This is a pointer to a function with the ++following definition: ++ void setspeed_function (unsigned int kHz). ++This function shall perform the transition to the new CPU frequency ++given as argument in kHz. Note that this argument is exactly the same ++as the one returned by cpufreq_verify_t validate. ++ ++ ++unsigned int freq.cur: The current CPU core frequency. Note that this ++is a requirement while the next two entries are optional. ++ ++ ++unsigned int freq.min (optional): The minimal CPU core frequency this ++CPU supports. This value may be limited further by the ++cpufreq_verify_t validate function, and so this value should be the ++minimal core frequency allowed "theoretically" on this system in this ++configuration. ++ ++ ++unsigned int freq.max (optional): The maximum CPU core frequency this ++CPU supports. This value may be limited further by the ++cpufreq_verify_t validate function, and so this value should be the ++maximum core frequency allowed "theoretically" on this system in this ++configuration. ++ ++ ++Some Requirements to CPUFreq architecture drivers ++------------------------------------------------- ++* Only call cpufreq_register() when the ability to switch CPU ++ frequencies is _verified_ or can't be missing ++* cpufreq_unregister() may only be called if cpufreq_register() has ++ been successfully(!) called before ++* All CPUs have to be set to the same speed whenever setspeed() is ++ called ++* Be aware that there is currently no error management in the ++ setspeed() code in the CPUFreq core. So only call yourself a ++ cpufreq_driver if you are really a working cpufreq_driver! ++ ++ ++ ++4.

It is not complete, any questions you have should be directed to ++ ++ ++The reference implementation is contained within serial_amba.c. ++ ++ ++ ++Low Level Serial Hardware Driver ++-------------------------------- ++ ++The low level serial hardware driver is responsible for supplying port ++information (defined by uart_port) and a set of control methods (defined ++by uart_ops) to the core serial driver. The low level driver is also ++responsible for handling interrupts for the port, and providing any ++console support. ++ ++ ++Console Support ++--------------- ++ ++The serial core provides a few helper functions. This includes identifing ++the correct port structure (via uart_get_console) and decoding command line ++arguments (uart_parse_options). ++ ++ ++Locking ++------- ++ ++Generally, all locking is done by the core driver, except for the interrupt ++functions. It is the responsibility of the low level hardware driver to ++perform the necessary locking there using info->lock. (since it is running ++in an interrupt, you only need to use spin_lock() and spin_unlock() from ++the interrupt handler). ++ ++ ++uart_ops ++-------- ++ ++The uart_ops structure is the main interface between serial_core and the ++hardware specific driver. It contains all the methods to control the ++hardware. ++ ++ tx_empty(port) ++ This function tests whether the transmitter fifo and shifter ++ for the port described by 'port' is empty. If it is empty, ++ this function should return TIOCSER_TEMT, otherwise return 0. ++ If the port does not support this operation, then it should ++ return TIOCSER_TEMT. ++ ++ set_mctrl(port, mctrl) ++ This function sets the modem control lines for port described ++ by 'port' to the state described by mctrl. The relevant bits ++ of mctrl are: ++ - TIOCM_RTS RTS signal. ++ - TIOCM_DTR DTR signal. ++ - TIOCM_OUT1 OUT1 signal. ++ - TIOCM_OUT2 OUT2 signal. ++ If the appropriate bit is set, the signal should be driven ++ active. If the bit is clear, the signal should be driven ++ inactive. ++ ++ get_mctrl(port) ++ Returns the current state of modem control inputs. The state ++ of the outputs should not be returned, since the core keeps ++ track of their state. The state information should include: ++ - TIOCM_DCD state of DCD signal ++ - TIOCM_CTS state of CTS signal ++ - TIOCM_DSR state of DSR signal ++ - TIOCM_RI state of RI signal ++ The bit is set if the signal is currently driven active. If ++ the port does not support CTS, DCD or DSR, the driver should ++ indicate that the signal is permanently active. If RI is ++ not available, the signal should not be indicated as active. ++ ++ stop_tx(port,from_tty) ++ Stop transmitting characters. This might be due to the CTS ++ line becoming inactive or the tty layer indicating we want ++ to stop transmission. ++ ++ start_tx(port,nonempty,from_tty) ++ start transmitting characters. (incidentally, nonempty will ++ always be nonzero, and shouldn't be used - it will be dropped). ++ ++ stop_rx(port) ++ Stop receiving characters; the port is in the process of ++ being closed. ++ ++ enable_ms(port) ++ Enable the modem status interrupts. ++ ++ break_ctl(port,ctl) ++ Control the transmission of a break signal. If ctl is ++ nonzero, the break signal should be transmitted. The signal ++ should be terminated when another call is made with a zero ++ ctl. ++ ++ startup(port,info) ++ Grab any interrupt resources and initialise any low level driver ++ state. Enable the port for reception. It should not activate ++ RTS nor DTR; this will be done via a separate call to set_mctrl. ++ ++ shutdown(port,info) ++ Disable the port, disable any break condition that may be in ++ effect, and free any interrupt resources. It should not disable ++ RTS nor DTR; this will have already been done via a separate ++ call to set_mctrl. ++ ++ change_speed(port,cflag,iflag,quot) ++ Change the port parameters, including word length, parity, stop ++ bits. Update read_status_mask and ignore_status_mask to indicate ++ the types of events we are interested in receiving. Relevant ++ cflag bits are: ++ CSIZE - word size ++ CSTOPB - 2 stop bits ++ PARENB - parity enable ++ PARODD - odd parity (when PARENB is in force) ++ CREAD - enable reception of characters (if not set, ++ still receive characters from the port, but ++ throw them away. ++ CRTSCTS - if set, enable CTS status change reporting ++ CLOCAL - if not set, enable modem status change ++ reporting. ++ Relevant iflag bits are: ++ INPCK - enable frame and parity error events to be ++ passed to the TTY layer. ++ BRKINT ++ PARMRK - both of these enable break events to be ++ passed to the TTY layer. ++ ++ IGNPAR - ignore parity and framing errors ++ IGNBRK - ignore break errors, If IGNPAR is also ++ set, ignore overrun errors as well. ++ The interaction of the iflag bits is as follows (parity error ++ given as an example): ++ Parity error INPCK IGNPAR ++ None n/a n/a character received ++ Yes n/a 0 character discarded ++ Yes 0 1 character received, marked as ++ TTY_NORMAL ++ Yes 1 1 character received, marked as ++ TTY_PARITY ++ ++ pm(port,state,oldstate) ++ perform any power management related activities on the specified ++ port. state indicates the new state (defined by ACPI D0-D3), ++ oldstate indicates the previous state. Essentially, D0 means ++ fully on, D3 means powered down. ++ ++ This function should not be used to grab any resources. ++ ++ type(port) ++ Return a pointer to a string constant describing the specified ++ port, or return NULL, in which case the string 'unknown' is ++ substituted. ++ ++ release_port(port) ++ Release any memory and IO region resources currently in use by ++ the port. ++ ++ request_port(port) ++ Request any memory and IO region resources required by the port. ++ If any fail, no resources should be registered when this function ++ returns, and it should return -EBUSY on failure. ++ ++ config_port(port,type) ++ Perform any autoconfiguration steps required for the port. `type` ++ contains a bit mask of the required configuration. UART_CONFIG_TYPE ++ indicates that the port requires detection and identification. ++ port->type should be set to the type found, or PORT_UNKNOWN if ++ no port was detected. ++ ++ UART_CONFIG_IRQ indicates autoconfiguration of the interrupt signal, ++ which should be probed using standard kernel autoprobing techniques. ++ This is not necessary on platforms where ports have interrupts ++ internally hard wired (eg, system on a chip implementations). ++ ++ verify_port(port,serinfo) ++ Verify the new serial port information contained within serinfo is ++ suitable for this port type. ++ ++ ioctl(port,cmd,arg) ++ Perform any port specific IOCTLs.

If we would switch back to interrupt mode as long as a key is pressed, ++ * we come right back to the interrupt, because the int. is level triggered ! ++ * The timer based scan of the seperate columns can also be done in one ++ * timer event (set fastscan to 1). ++ * ++ * Summary: ++ * The design of this keyboard controller chip is stupid at all ! ++ * ++ * Matrix translation: ++ * The matrix translation table is based on standard XT scancodes. Maybe ++ * you have to adjust the KEYISPRINTABLE macro if you set other codes. ++ * ++ * HandyKey: ++ * ++ * On small matrix keyboards you don't have enough keys for operation. ++ * The intention was to implement a operation mode as it's used on handys. ++ * You can rotate trough four scancode levels and produce e.g. with a 4x3 ++ * matrix 4*3*4 = 48 different keycodes. That's basicly enough for editing ++ * filenames or things like that. The HandyKey function takes care about ++ * nonprintable keys like cursors, backspace, del ... ++ * If a key is pressed and is a printable keycode, the code is put to the ++ * main keyboard handler and a cursor left is applied. If you press the same ++ * key again, the current character is deleted and the next level character ++ * is applied. (e.g. 1, a, b, c, 1 ....). If you press a different key, the ++ * driver applies cursor right, before processing the new key. ++ * The autocomplete feature moves the cursor right, if you do not press a ++ * key within a programmable time. ++ * If HandyKey is off, the keyboard behaviour is that of a standard keyboard ++ * HandyKey can be en/disabled from userspace with the proc/keyboard entry ++ * ++ * proc/keyboard: ++ * ++ * Read access gives back the actual state of the HandyKey function ++ * h:0 Disabled ++ * h:1 Enabled ++ * Write access has two functions. Changing the HandyKey mode and applying ++ * a different scancode translation table. ++ * Syntax is: h:0 disable Handykey ++ * h:1 enabled Handykey ++ * t:array[256] of bytes Transfer translation table ++ */ ++ ++#include ++#include ++#include ++#include ++#include ++#include ++#include ++#include ++#include ++#include ++#include ++#include ++#include ++#include ++#include ++#include ++#include ++#include ++ ++#include ++#include ++#include ++#include ++#include ++ ++#include ++#include ++ ++void clps711x_kbd_init_hw(void);

The video data is captured to ++ * the VGA memory, where the CyberPro can overlay (by chromakeying) the ++ * data onto the VGA display. ++ * ++ * The CyberPro also has some nifty features, including a second overlay ++ * and picture in picture mode. We do not currently use these features. ++ * ++ * Power Saving ++ * ------------ ++ * Please note that rev.5 NetWinders have the ability to hold the SAA7111 ++ * decoder chip into reset, which saves power. The only time at which ++ * this is done is when the driver is unloaded, which implies that this ++ * is compiled as a module. ++ * ++ * In this case, you will want the kernel to automatically load this ++ * driver when required. Place the following line in /etc/modules.conf ++ * to enable this: ++ * ++ * alias char-major-81-0 cyberpro ++ * ++ * The relevant modules will be automatically loaded by modprobe on a ++ * as and when needed basis. ++ * ++ * Capture resolution ++ * ------------------ ++ * The maximum useful capture resolution is: ++ * 625-line UK: 716x576 ++ * 525-line US: ? ++ * ++ * Bugs ++ * ---- ++ * 1.

Really, we want to do scatter BM-DMA. Is the CyberPro capable of this? ++ * The Cyberpro seems to randomly scribble to various PCI addresses if you ++ * transfer >16 words. ++ * 5. We shouldn't ignore O_NONBLOCK when reading a frame. ++ * 6. The incoming stream on the NetWinder is CCIR656, which is YUV422. ++ * CyberPro docs also call the format we capture and overlay "YUV422", ++ * but we actually seem to have Y, U, Y, V bytes (is this YUYV format?) ++ */ ++#include ++#include ++#include ++#include ++#include ++#include ++#include ++#include ++#include ++#include ++#include ++#include ++#include ++#include ++ ++#include ++#include ++#include ++#include ++ ++MODULE_AUTHOR("Russell King "); ++MODULE_DESCRIPTION("CyberPro v4l video grabber"); ++MODULE_LICENSE("GPL"); ++ ++#include "../../video/cyber2000fb.h" ++ ++/* ++ * These enable various experimental features.
