If there are multiple +batteries with their own chargers acting independently in a system, +the system may need multiple instances of Charger Manager. + +1. Introduction +=============== + +Charger Manager supports the following: + +* Support for multiple chargers (e.g., a device with USB, AC, and solar panels) + A system may have multiple chargers (or power sources) and some of + they may be activated at the same time. Each charger may have its + own power-supply-class and each power-supply-class can provide + different information about the battery status. This framework + aggregates charger-related information from multiple sources and + shows combined information as a single power-supply-class. + +* Support for in suspend-to-RAM polling (with suspend_again callback) + While the battery is being charged and the system is in suspend-to-RAM, + we may need to monitor the battery health by looking at the ambient or + battery temperature. We can accomplish this by waking up the system + periodically. However, such a method wakes up devices unncessary for + monitoring the battery health and tasks, and user processes that are + supposed to be kept suspended. That, in turn, incurs unnecessary power + consumption and slow down charging process. Or even, such peak power + consumption can stop chargers in the middle of charging + (external power input < device power consumption), which not + only affects the charging time, but the lifespan of the battery. + + Charger Manager provides a function "cm_suspend_again" that can be + used as suspend_again callback of platform_suspend_ops. If the platform + requires tasks other than cm_suspend_again, it may implement its own + suspend_again callback that calls cm_suspend_again in the middle. + Normally, the platform will need to resume and suspend some devices + that are used by Charger Manager. + +2. Global Charger-Manager Data related with suspend_again +======================================================== +In order to setup Charger Manager with suspend-again feature +(in-suspend monitoring), the user should provide charger_global_desc +with setup_charger_manager(struct charger_global_desc *). +This charger_global_desc data for in-suspend monitoring is global +as the name suggests. Thus, the user needs to provide only once even +if there are multiple batteries. If there are multiple batteries, the +multiple instances of Charger Manager share the same charger_global_desc +and it will manage in-suspend monitoring for all instances of Charger Manager. + +The user needs to provide all the two entries properly in order to activate +in-suspend monitoring: + +struct charger_global_desc { + +char *rtc_name; + : The name of rtc (e.g., "rtc0") used to wakeup the system from + suspend for Charger Manager. The alarm interrupt (AIE) of the rtc + should be able to wake up the system from suspend.

If there is any other wakeup source triggered the + wakeup, it should return false. If the "rtc" is the only wakeup + reason, it should return true. +}; + +3. How to setup suspend_again +============================= +Charger Manager provides a function "extern bool cm_suspend_again(void)". +When cm_suspend_again is called, it monitors every battery. The suspend_ops +callback of the system's platform_suspend_ops can call cm_suspend_again +function to know whether Charger Manager wants to suspend again or not. +If there are no other devices or tasks that want to use suspend_again +feature, the platform_suspend_ops may directly refer to cm_suspend_again +for its suspend_again callback. + +The cm_suspend_again() returns true (meaning "I want to suspend again") +if the system was woken up by Charger Manager and the polling +(in-suspend monitoring) results in "normal". + +4.

Arguments and +returned values in frames are the norm, making it a challenge to +extend the existing API to compressed data streams. + +In recent years, audio digital signal processors (DSP) were integrated +in system-on-chip designs, and DSPs are also integrated in audio +codecs. Processing compressed data on such DSPs results in a dramatic +reduction of power consumption compared to host-based +processing. Support for such hardware has not been very good in Linux, +mostly because of a lack of a generic API available in the mainline +kernel. + +Rather than requiring a compability break with an API change of the +ALSA PCM interface, a new 'Compressed Data' API is introduced to +provide a control and data-streaming interface for audio DSPs. + +The design of this API was inspired by the 2-year experience with the +Intel Moorestown SOC, with many corrections required to upstream the +API in the mainline kernel instead of the staging tree and make it +usable by others. + +Requirements + +The main requirements are: + +- separation between byte counts and time. Compressed formats may have + a header per file, per frame, or no header at all. The payload size + may vary from frame-to-frame. As a result, it is not possible to + estimate reliably the duration of audio buffers when handling + compressed data. Dedicated mechanisms are required to allow for + reliable audio-video synchronization, which requires precise + reporting of the number of samples rendered at any given time. + +- Handling of multiple formats. PCM data only requires a specification + of the sampling rate, number of channels and bits per sample. In + contrast, compressed data comes in a variety of formats. Audio DSPs + may also provide support for a limited number of audio encoders and + decoders embedded in firmware, or may support more choices through + dynamic download of libraries. + +- Focus on main formats. This API provides support for the most + popular formats used for audio and video capture and playback. It is + likely that as audio compression technology advances, new formats + will be added. + +- Handling of multiple configurations.

The new API needs to provide a generic way of listing these + formats. + +- Rendering/Grabbing only. This API does not provide any means of + hardware acceleration, where PCM samples are provided back to + user-space for additional processing. This API focuses instead on + streaming compressed data to a DSP, with the assumption that the + decoded samples are routed to a physical output or logical back-end. + + - Complexity hiding. Existing user-space multimedia frameworks all + have existing enums/structures for each compressed format. This new + API assumes the existence of a platform-specific compatibility layer + to expose, translate and make use of the capabilities of the audio + DSP, eg. Android HAL or PulseAudio sinks. By construction, regular + applications are not supposed to make use of this API. + + +Design + +The new API shares a number of concepts with with the PCM API for flow +control. Start, pause, resume, drain and stop commands have the same +semantics no matter what the content is. + +The concept of memory ring buffer divided in a set of fragments is +borrowed from the ALSA PCM API. However, only sizes in bytes can be +specified. + +Seeks/trick modes are assumed to be handled by the host. + +The notion of rewinds/forwards is not supported. Data committed to the +ring buffer cannot be invalidated, except when dropping all buffers. + +The Compressed Data API does not make any assumptions on how the data +is transmitted to the audio DSP. DMA transfers from main memory to an +embedded audio cluster or to a SPI interface for external DSPs are +possible. As in the ALSA PCM case, a core set of routines is exposed; +each driver implementer will have to write support for a set of +mandatory routines and possibly make use of optional ones. + +The main additions are + +- get_caps +This routine returns the list of audio formats supported. Querying the +codecs on a capture stream will return encoders, decoders will be +listed for playback streams. + +- get_codec_caps For each codec, this routine returns a list of +capabilities. The intent is to make sure all the capabilities +correspond to valid settings, and to minimize the risks of +configuration failures. For example, for a complex codec such as AAC, +the number of channels supported may depend on a specific profile. If +the capabilities were exposed with a single descriptor, it may happen +that a specific combination of profiles/channels/formats may not be +supported. Likewise, embedded DSPs have limited memory and cpu cycles, +it is likely that some implementations make the list of capabilities +dynamic and dependent on existing workloads. In addition to codec +settings, this routine returns the minimum buffer size handled by the +implementation. This information can be a function of the DMA buffer +sizes, the number of bytes required to synchronize, etc, and can be +used by userspace to define how much needs to be written in the ring +buffer before playback can start. + +- set_params +This routine sets the configuration chosen for a specific codec.
