USB4 Tunneled Protocols Assignment

This group of functions covers VSE capability to work with USB4 Tunneled Protocols for USB4 HS Tunneled Packets.

SetUsb4TunneledProtocol()

Depricated; use SetUsb4TunProtocol() instead.

SetUsb4TunProtocol()

By default, the assignments in the Decoding Settings are used in VSE. Use this function to override it with a new Tunneled Protocol, Generation, and Link Width to a HopID/Channel.

This function does not change the assignments in Decoding Settings.

SetUsb4TunProtocol ( hop_id, channel, tunneled_protocol, gen_type, link_width )

Return Values

If channel number is not valid and hence protocol assignment can not be set, the function returns 0. In all other cases it returns 1.

Example

SetUsb4TunProtocol(8, _USB4_HS_ANALYZER_LEFT, _USB4_TUN_USB, _USB4_TUN_USB3_GEN_T, _LINK_WIDTH_X2);

SetUsb4TunProtocol(9, _USB4_HS_ANALYZER_LEFT, _USB4_TUN_PCIE, 0, _LINK_WIDTH_UNKNOWN);

GetUsb4TunneledProtocol()

Get the assigned USB4 Tunneled Protocol to a specified HopID and channel.

GetUsb4TunneledProtocol( hop_id, channel, tunneled_protocol )

Return Values

May return one of the values from the list of constants for USB4 Tunneled Protocols (see SetUsb4TunProtocol()).

Example

if(in.TraceEvent == _USB4_HS_TUNNELED_PKT)
{
  protocol = GetUsb4TunneledProtocol(in.Header_HopID, in.Channel);
}
