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.)

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.

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".

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 separately (separate 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.

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. IOCTL commands must be defined -+ using the standard numbering system found in -+ -+ -+Other notes -+----------- -+ -+It is intended some day to drop the 'unused' entries from uart_port, and -+allow low level drivers to register their own individual uart_port's with -+the core.

It sets all column drivers -+ * high. If any key is pressed, a interrupt occures. Now a separate scan of -+ * each column is done. This scan is timer based, because we use a keyboard -+ * interface with decoupling capacitors (neccecary if you want to survive -+ * EMC compliance tests). Always one line is set high. When next timer event -+ * occures the scan data on port A are valid. This makes also sure, that no -+ * spurious keys are scanned. The kbd int on these CPU's is not deglitched! -+ * After scanning all columns, we switch back to int mode, if no key is -+ * pressed. If any is pressed we reschedule the scan within a programmable -+ * delay. 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 separate 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.

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. The CyberPro chip seems to be prone to randomly scribbling over VGA -+ * memory [hopefully fixed with new capture enable/freeze stuff] -+ * 2. read()ing pauses video capture, and sometimes triggers bug 1. -+ * 3. mmap() is not supported (requires BM-DMA - see bug 4) -+ * 4. 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.
