Define Documentation

#define pbc_ERROR_LOG_SIZE   (256)

The size (in entries) of the PBC error log ring buffer.

#define PBC_ERROR_NUM_REG_ENTRIES   (sizeof (pbc_errorRegList) / sizeof (pbc_errorRegList[0]))

Number of elements in the pbc_errorRegList array.

Function Documentation

void Pbc_ErrCheck (  void   )

Check for errors reported in PPCI registers. Checks error registers within the PPCI bridge chip and reports any pending errors. Returns: Nothing.

void PBC_ErrorLog (  const int  errorCode  )

Log error message in primary boot code. Right now, just print out to the screen. Later, we will log the errors in telemetry. Parameters: errorCode  Integer error code from PBC_msg.h

void Pbc_ErrorLogInit (   )

Initialize PBC error log. Initialize error long structure. All counters cleared. Ring buffer is reset. Last error is erased.

void Pbc_ErrorLogPop (  void   )

Pop oldest entry from the error ring. Pop oldest entry from the error ring. The "first" pointer is moved forward by one error entry. This routine has no effect if the error log is empty.

void Pbc_ErrorLogStats (  unsigned int *  totalCount, unsigned int *  ringCount, unsigned int *  queuedCode, unsigned int *  lastCode )

Get state of PBC error log. Return information about the error log. Returns both error counts (total errors & number of errors in the ring). Also returns the oldest and lastest error codes. The return contents of lastCode will only be valid if totalCount is non-zero. The return contents of firstCode will only be valid if ringCount is non-zero. Parameters: totalCount  Total number of errors reported. ringCount  Total number of errors in the error ring. queuedCode  The next error code at the "front" of the ring. lastCode  Newst error code.

Variable Documentation

pbc_errorRegList

List of PPCI error register bits to monitor.

pbc_masterErrorLog

The PBC master error log. I don't make this static so the name gets in the symbol table. That way I can dump the structure.
