5.2.1.3.12 Getting Values of the Fields not present in Input Context

As mentioned earlier, not all the possible fields of USB3 packets are passed as members of Input Context. The

following are examples of using GetHexPktField and GetDecodedPktField functions to get values of the fields

not present in Input Context.

If( in.TraceEvent == _USB3_LMP_PKT )

{

# Example of using decoded packet information for LMPs.

# ‘SubType’ field,

# String value

str = FormatEx("\tSubType(str) = ‘%s’", GetDecodedPktField("SubType"));

ReportText( str );

# Hex Value

val = GetHexPktField ( "SubType" );

str = FormatEx( "\tSubType(hex) = 0x%X\n", val );

ReportText( str );

# ‘Hseq’ field

# String value

str = FormatEx( "\tHseq(str) = ‘%s’", GetDecodedPktField ( "Hseq" ) );

ReportText( str );

# Hex Value

val = GetHexPktField ( "Hseq" );

str = FormatEx( "\tHseq(hex) = 0x%X\n", val );

ReportText( str );

}

if( ( in.TraceEvent == _USB3_TP_PKT ) && ( in.SubType == TP_ACK ) )

{

# Example of using decoded packet information for TPs.

# ‘SeqN’ field

# String value

str = FormatEx( "\tSeqN(str) = ‘%s’", GetDecodedPktField ( "SeqN" ) );

ReportText( str );

# Hex Value

val = GetHexPktField ( "SeqN" );

str = FormatEx( "\tSeqN(hex) = 0x%X\n", val );

ReportText( str );

# ‘NumP’ field

# String value

str = FormatEx( "\tNumP(str) = ‘%s’", GetDecodedPktField ( "NumP" ) );

ReportText( str );
