Raw Normal View History

Linux-2.6.12-rc2 Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!

# CPUfreq core
cpufreq: remove CONFIG_CPU_FREQ_TABLE CONFIG_CPU_FREQ_TABLE will be always enabled when cpufreq framework is used, as cpufreq core depends on it. So, we don't need this CONFIG option anymore as it is not configurable. Remove CONFIG_CPU_FREQ_TABLE and update its users.

PM / OPP: Move cpufreq specific OPP functions out of generic OPP library CPUFreq specific helper functions for OPP (Operating Performance Points) now use generic OPP functions that allow CPUFreq to be be moved back into CPUFreq framework. This allows for independent modifications or future enhancements as needed isolated to just CPUFreq framework alone. Here, we just move relevant code and documentation to make this part of CPUFreq infrastructure.

cpufreq / governor: Fix problem with cpufreq_ondemand or cpufreq_conservative Since commit 2aacdff entitled "cpufreq: Move common part from governors to separate file", whenever the drivers that depend on this new file (cpufreq_ondemand or cpufreq_conservative) are built as modules, a new module named cpufreq_governor is created because the Makefile includes cpufreq_governor.o twice. As drivers/cpufreq/cpufreq_governor.c contains no MODULE directives, the resulting module has no license specified, which results in logging of a "module license 'unspecified' taints kernel". In addition, a number of globals are exported GPL only, and are therefore not available. This fix establishes a new boolean configuration variable that forces cpufreq_governor.o to be linked into the kernel whenever either cpufreq_ondemand or cpufreq_conservative is selected.

cpufreq: cpu0: rename driver and internals to 'cpufreq_dt' The naming convention of this driver was always under the scanner, people complained that it should have a more generic name than cpu0, as it manages all CPUs that are sharing clock lines. Also, in future it will be modified to support any number of clusters with separate clock/voltage lines. Lets rename it to 'cpufreq_dt' from 'cpufreq_cpu0'.

cpufreq: dt: Add generic platform-device creation support Multiple platforms are using the generic cpufreq-dt driver now, and all of them are required to create a platform device with name "cpufreq-dt", in order to get the cpufreq-dt probed. Many of them do it from platform code, others have special drivers just to do that. It would be more sensible to do this at a generic place, where all such platform can mark their entries. This patch adds a separate file to get this device created. Currently the compat list of platforms that we support is empty, and will be filled in as and when we move platforms to use it. It always compiles as part of the kernel and so doesn't need a module-exit operation.

When built into the the kernel this driver will be the preferred scaling driver for Sandy bridge processors. In addition to the interfaces provided by the cpufreq subsystem for controlling scaling drivers. The user may control the behavior of the driver via three sysfs files located in "/sys/devices/system/cpu/intel_pstate". max_perf_pct: limits the maximum P state that will be requested by the driver stated as a percentage of the avail performance. min_perf_pct: limits the minimum P state that will be requested by the driver stated as a percentage of the avail performance. no_turbo: limits the driver to selecting P states below the turbo frequency range.

The driver is divided into two parts: - Core driver: Generic and shared across all big LITTLE SoC's - Glue drivers: Per platform drivers providing ops to the core driver This patch adds in a generic glue driver which would extract information from Device Tree.

The major difference being interrupt notification for frequency change. Also, OPP library is used for device tree parsing to get different parameters like frequency, voltage etc. Since the opp library sorts the frequency table in ascending order so they are again re-arranged in descending order.

cpufreq: mediatek: Add MT8173 cpufreq driver Mediatek MT8173 is an ARMv8 based quad-core (2*Cortex-A53 and 2*Cortex-A72) SoC with duall clusters. For each cluster, two voltage inputs, Vproc and Vsram are supplied by two regulators. For the big cluster, two regulators come from different PMICs. In this case, when scaling voltage inputs of the cluster, the voltages of two regulator inputs need to be controlled by software explicitly under the SoC specific limitation: 100mV < Vsram - Vproc < 200mV which is called 'voltage tracking' mechanism. And when scaling the frequency of cluster clock input, the input MUX need to be parented to another "intermediate" stable PLL first and reparented to the original PLL once the original PLL is stable at the target frequency. This patch implements those mechanisms to enable CPU DVFS support for Mediatek MT8173 SoC.

cpufreq: ti: Add cpufreq driver to determine available OPPs at runtime Some TI SoCs, like those in the AM335x, AM437x, DRA7x, and AM57x families, have different OPPs available for the MPU depending on which specific variant of the SoC is in use. This can be determined through use of the revision and an eFuse register present in the silicon. Introduce a ti-cpufreq driver that can read the aformentioned values and provide them as version matching data to the opp framework. Through this the opp-supported-hw dt binding that is part of the operating-points-v2 table can be used to indicate availability of OPPs for each device. This driver also creates the "cpufreq-dt" platform_device after passing the version matching data to the OPP framework so that the cpufreq-dt handles the actual cpufreq implementation. Even without the necessary data to pass the version matching data the driver will still create this device to maintain backwards compatibility with operating-points v1 tables.

cpufreq: powernv: cpufreq driver for powernv platform Backend driver to dynamically set voltage and frequency on IBM POWER non-virtualized platforms. Power management SPRs are used to set the required PState. This driver works in conjunction with cpufreq governors like 'ondemand' to provide a demand based frequency and voltage setting on IBM POWER non-virtualized platforms. PState table is obtained from OPAL v3 firmware through device tree. powernv_cpufreq back-end driver would parse the relevant device-tree nodes and initialise the cpufreq subsystem on powernv platform. The code was originally written by svaidy@linux.vnet.ibm.com. Over time it was modified to accomodate bug-fixes as well as updates to the the cpu-freq core. Relevant portions of the change logs corresponding to those modifications are noted below: * The policy->cpus needs to be populated in a hotplug-invariant manner instead of using cpu_sibling_mask() which varies with cpu-hotplug. This is because the cpufreq core code copies this content into policy->related_cpus mask which should not vary on cpu-hotplug. [Authored by srivatsa.bhat@linux.vnet.ibm.com] * Create a helper routine that can return the cpu-frequency for the corresponding pstate_id. Also, cache the values of the pstate_max, pstate_min and pstate_nominal and nr_pstates in a static structure so that they can be reused in the future to perform any validations. [Authored by ego@linux.vnet.ibm.com] * Create a driver attribute named cpuinfo_nominal_freq which creates a sysfs read-only file named cpuinfo_nominal_freq. Export the frequency corresponding to the nominal_pstate through this interface. Nominal frequency is the highest non-turbo frequency for the platform. This is generally used for setting governor policies from user space for optimal energy efficiency. [Authored by ego@linux.vnet.ibm.com] * Implement a powernv_cpufreq_get(unsigned int cpu) method which will return the current operating frequency. Export this via the sysfs interface cpuinfo_cur_freq by setting powernv_cpufreq_driver.get to powernv_cpufreq_get().
