Function Documentation

◆ log_frontend_stmesp_dummy_write()

void log_frontend_stmesp_dummy_write ( void  )

Perform a dummy write to STMESP.

It can be used to force flushing STM data.

◆ log_frontend_stmesp_etr_ready()

int log_frontend_stmesp_etr_ready ( void  )

Notify frontend that ETR/STM is ready.

Log frontend optionally dumps buffered data and start to write to the STM stimulus port.

Note
Function is applicable only for the domain that performs initial ETR/STM setup.
Return values
0on success.
-EIOif there was an internal failure.

◆ log_frontend_stmesp_pre_sleep()

void log_frontend_stmesp_pre_sleep ( void  )

Hook to be called before going to sleep.

Hook writes dummy data to the STM Stimulus Port to ensure that all logging data is flushed.

◆ log_frontend_stmesp_tp()

static void log_frontend_stmesp_tp ( uint16_t  x)
inlinestatic

Trace point.

Write a trace point information using STM. Number of unique trace points is limited to 65536 - CONFIG_LOG_FRONTEND_STMESP_TP_CHAN_BASE per core.

Parameters
xTrace point ID.

◆ log_frontend_stmesp_tp_d32()

static void log_frontend_stmesp_tp_d32 ( uint16_t  x,
uint32_t  d 
)
inlinestatic

Trace point with 32 bit data.

Write a trace point information using STM. Number of unique trace points is limited to 65536 - CONFIG_LOG_FRONTEND_STMESP_TP_CHAN_BASE per core.

Parameters
xTrace point ID.
dData. 32 bit word.
