Function Documentation

◆ SYSM_CheckNotifications()

void SYSM_CheckNotifications ( void  )

overall system monitoring

checks notifications (state and timestamps) of all system-relevant tasks or functions all checks should be customized corresponding to its timing and state requirements

early exit if nothing to do

Definition at line 150 of file sys_mon.c.

Here is the call graph for this function:

◆ SYSM_ClearAllTimingViolations()

void SYSM_ClearAllTimingViolations ( void  )

Clears all timing violations (both current and recorded)

This function clears all indicators that a timing violation has happened.

Definition at line 232 of file sys_mon.c.

Here is the call graph for this function:

◆ SYSM_ConvertRecordedTimingsToViolation()

static bool SYSM_ConvertRecordedTimingsToViolation ( uint32_t  duration,
uint32_t  timestampEnter 
)
static

Convert recorded timings into a decision (bool) whether the timing has been violated or not.

Timing has been violated if both duration or timestamp are not equal to zero

Parameters
[in]durationduration in ticks
[in]timestampEnterentry timestamp in ticks
Returns
bool describing whether this is a violation (true) or not (false)

Definition at line 129 of file sys_mon.c.

◆ SYSM_CopyFramStruct()

void SYSM_CopyFramStruct ( const FRAM_SYS_MON_RECORD_s *const  kpkFrom,
FRAM_SYS_MON_RECORD_s pTo 
)

Copy from the from entry to the to entry.

Parameters
[in]kpkFrompointer to the origin struct
[out]pTopointer to the destination struct

Definition at line 270 of file sys_mon.c.

◆ SYSM_GetRecordedTimingViolations()

void SYSM_GetRecordedTimingViolations ( SYSM_TIMING_VIOLATION_RESPONSE_s pAnswer)

Returns the timing violation flags determined from fram state.

This function reads the timing states and determines if a violation has occurred.

Parameters
[out]pAnswerpointer to a SYSM_TIMING_VIOLATION_RESPONSE_s struct that will be filled by the function

Definition at line 200 of file sys_mon.c.

Here is the call graph for this function:

◆ SYSM_Init()

STD_RETURN_TYPE_e SYSM_Init ( void  )

initialization function for system monitoring

Has to be called once after startup to initialize and check system monitoring related functionality

Returns
STD_OK if no configuration error detected, otherwise STD_NOT_OK

Definition at line 138 of file sys_mon.c.

Here is the call graph for this function:

◆ SYSM_Notify()

void SYSM_Notify ( SYSM_TASK_ID_e  taskId,
SYSM_NOTIFY_TYPE_e  state,
uint32_t  timestamp 
)

Sets needed bits to indicate that a task is running.

Has to be called in every function using the system monitoring.

Parameters
taskIdtask id to notify system monitoring
statewhether function has been called at entry or exit
timestamptime

Definition at line 183 of file sys_mon.c.

Here is the call graph for this function:

◆ SYSM_RecordTimingViolation()

static void SYSM_RecordTimingViolation ( SYSM_TASK_ID_e  taskId,
uint32_t  taskDuration,
uint32_t  timestampEnter 
)
static

Records the violation of a timing in non volatile memory.

Parameters
[in]taskIdid of the violating task
[in]taskDurationduration of the task when recording the violation
[in]timestampEntertimestamp that the task has entered

Definition at line 95 of file sys_mon.c.

◆ SYSM_UpdateFramData()

void SYSM_UpdateFramData ( void  )

Commits the stored changes to FRAM if necessary.

Writing to FRAM is costly (in terms of computation time), therefore it is decoupled from the main task of the sys mon module. When called, this function checks the flag sysm_flagFramCopyHasChanges and writes to FRAM if there are changes.

Definition at line 256 of file sys_mon.c.

Here is the call graph for this function:

◆ TEST_SYSM_GetNotifications()

SYSM_NOTIFICATION_s* TEST_SYSM_GetNotifications ( void  )

Definition at line 290 of file sys_mon.c.

Variable Documentation

◆ sysm_flagFramCopyHasChanges

volatile bool sysm_flagFramCopyHasChanges = false
static

flag, indicating that the FRAM entry has been changed and should be written

Definition at line 71 of file sys_mon.c.

◆ sysm_localFramCopy

FRAM_SYS_MON_RECORD_s sysm_localFramCopy = {0}
static

local shadow copy of the FRAM entry

Definition at line 68 of file sys_mon.c.

◆ sysm_notifications
