It often15runs on a Cortex-M processor and provides an abstraction to many of the16underlying features of the hardware. The primary purpose of the SM is to allow17isolation between software running on different cores in the SoC. It does this18by having exclusive access to critical resources such as those controlling19power, clocks, reset, PMIC, etc. and then providing an RPC interface to those20clients. This allows the SM to provide access control, arbitration, and21aggregation policies for those shared critical resources.22 23SM introduces a concept Logic Machine(LM) which is analogous to VM and each has24its own instance of SCMI. All normal SCMI calls only apply to that LM. That25includes boot, shutdown, reset, suspend, wake, etc. Each LM (e.g. A55 and M7)26are completely isolated from the others and each LM has its own communication27channels talking to the same SCMI server.28 29This document covers all the information necessary to understand, maintain,30port, and deploy the SM on supported processors.31 32The SM implements an interface compliant with the Arm SCMI Specification33with additional vendor specific extensions.34 35SCMI_BBM: System Control and Management BBM Vendor Protocol36==============================================================37 38This protocol is intended provide access to the battery-backed module. This39contains persistent storage (GPR), an RTC, and the ON/OFF button. The protocol40can also provide access to similar functions implemented via external board41components. The BBM protocol provides functions to:42 43- Describe the protocol version.44- Discover implementation attributes.45- Read/write GPR46- Discover the RTCs available in the system.47- Read/write the RTC time in seconds and ticks48- Set an alarm (per LM) in seconds49- Get notifications on RTC update, alarm, or rollover.50- Get notification on ON/OFF button activity.51 52For most SoC, there is one on-chip RTC (e.g. in BBNSM) and this is RTC ID 0.53Board code can add additional GPR and RTC.54 55GPR are not aggregated. The RTC time is also not aggregated. Setting these56sets for all so normally exclusive access would be granted to one agent for57each. However, RTC alarms are maintained for each LM and the hardware is58programmed with the next nearest alarm time. So only one agent in an LM should59be given access rights to set an RTC alarm.60 61Commands:62_________63 64PROTOCOL_VERSION65~~~~~~~~~~~~~~~~66 67message_id: 0x068protocol_id: 0x8169 70+---------------+--------------------------------------------------------------+71|Return values |72+---------------+--------------------------------------------------------------+73|Name |Description |74+---------------+--------------------------------------------------------------+75|int32 status | See ARM SCMI Specification for status code definitions. |76+---------------+--------------------------------------------------------------+77|uint32 version | For this revision of the specification, this value must be |78| | 0x10000. |79+---------------+--------------------------------------------------------------+80 81PROTOCOL_ATTRIBUTES82~~~~~~~~~~~~~~~~~~~83 84message_id: 0x185protocol_id: 0x8186 87+---------------+--------------------------------------------------------------+88|Return values |89+------------------+-----------------------------------------------------------+90|Name |Description |91+------------------+-----------------------------------------------------------+92|int32 status | See ARM SCMI Specification for status code definitions. |93+------------------+-----------------------------------------------------------+94|uint32 attributes | Bits[31:8] Number of RTCs. |95| | Bits[15:0] Number of persistent storage (GPR) words. |96+------------------+-----------------------------------------------------------+97 98PROTOCOL_MESSAGE_ATTRIBUTES99~~~~~~~~~~~~~~~~~~~~~~~~~~~100 101message_id: 0x2102protocol_id: 0x81103 104+---------------+--------------------------------------------------------------+105|Return values |106+------------------+-----------------------------------------------------------+107|Name |Description |108+------------------+-----------------------------------------------------------+109|int32 status |SUCCESS: in case the message is implemented and available |110| |to use. |111| |NOT_FOUND: if the message identified by message_id is |112| |invalid or not implemented |113+------------------+-----------------------------------------------------------+114|uint32 attributes |Flags that are associated with a specific function in the |115| |protocol.
