It often +runs on a Cortex-M processor and provides an abstraction to many of the +underlying features of the hardware. The primary purpose of the SM is to allow +isolation between software running on different cores in the SoC. It does this +by having exclusive access to critical resources such as those controlling +power, clocks, reset, PMIC, etc. and then providing an RPC interface to those +clients. This allows the SM to provide access control, arbitration, and +aggregation policies for those shared critical resources. + +SM introduces a concept Logic Machine(LM) which is analogous to VM and each has +its own instance of SCMI. All normal SCMI calls only apply to that LM. That +includes boot, shutdown, reset, suspend, wake, etc. Each LM (e.g. A55 and M7) +are completely isolated from the others and each LM has its own communication +channels talking to the same SCMI server. + +This document covers all the information necessary to understand, maintain, +port, and deploy the SM on supported processors. + +The SM implements an interface compliant with the Arm SCMI Specification +with additional vendor specific extensions. + +SCMI_BBM: System Control and Management BBM Vendor Protocol +============================================================== + +This protocol is intended provide access to the battery-backed module. This +contains persistent storage (GPR), an RTC, and the ON/OFF button. The protocol +can also provide access to similar functions implemented via external board +components. The BBM protocol provides functions to: + +- Describe the protocol version. +- Discover implementation attributes. +- Read/write GPR +- Discover the RTCs available in the system. +- Read/write the RTC time in seconds and ticks +- Set an alarm (per LM) in seconds +- Get notifications on RTC update, alarm, or rollover. +- Get notification on ON/OFF button activity. + +For most SoC, there is one on-chip RTC (e.g. in BBNSM) and this is RTC ID 0. +Board code can add additional GPR and RTC. + +GPR are not aggregated. The RTC time is also not aggregated. Setting these +sets for all so normally exclusive access would be granted to one agent for +each. However, RTC alarms are maintained for each LM and the hardware is +programmed with the next nearest alarm time. So only one agent in an LM should +be given access rights to set an RTC alarm. + +Commands: +_________ + +PROTOCOL_VERSION +~~~~~~~~~~~~~~~~ + +message_id: 0x0 +protocol_id: 0x81 + ++---------------+--------------------------------------------------------------+ +|Return values | ++---------------+--------------------------------------------------------------+ +|Name |Description | ++---------------+--------------------------------------------------------------+ +|int32 status | See ARM SCMI Specification for status code definitions. | ++---------------+--------------------------------------------------------------+ +|uint32 version | For this revision of the specification, this value must be | +| | 0x10000. | ++---------------+--------------------------------------------------------------+ + +PROTOCOL_ATTRIBUTES +~~~~~~~~~~~~~~~~~~~ + +message_id: 0x1 +protocol_id: 0x81 + ++---------------+--------------------------------------------------------------+ +|Return values | ++------------------+-----------------------------------------------------------+ +|Name |Description | ++------------------+-----------------------------------------------------------+ +|int32 status | See ARM SCMI Specification for status code definitions. | ++------------------+-----------------------------------------------------------+ +|uint32 attributes | Bits[31:8] Number of RTCs. | +| | Bits[15:0] Number of persistent storage (GPR) words. | ++------------------+-----------------------------------------------------------+ + +PROTOCOL_MESSAGE_ATTRIBUTES +~~~~~~~~~~~~~~~~~~~~~~~~~~~ + +message_id: 0x2 +protocol_id: 0x81 + ++---------------+--------------------------------------------------------------+ +|Return values | ++------------------+-----------------------------------------------------------+ +|Name |Description | ++------------------+-----------------------------------------------------------+ +|int32 status |SUCCESS: in case the message is implemented and available | +| |to use. | +| |NOT_FOUND: if the message identified by message_id is | +| |invalid or not implemented | ++------------------+-----------------------------------------------------------+ +|uint32 attributes |Flags that are associated with a specific function in the | +| |protocol.
