Hot-plug-detect (HPD) handling
HPD events can be detected in the form of connection/disconnection or pulse events. The
events can be polled for, or interrupts can be enabled in the system and handlers can be set in
the application.
When the HPD signal is connected to an interrupt controller in the system, the SW driver steers
the flow of software to run an HPD pulse handler if an HPD pulse occurs, or an HPD event
handler if an HPD event occurs.
Multi-stream Transport (MST) Support
The SW driver handles MST mode functionality, including sideband messaging, topology
discovery, virtual channel payload ID table management, and directing streams to different sink
(leaf) nodes in the MST topology, up to a limitation of four streams.
Refer to Sections 2.5, 2.6 and 2.11 of the DP v1.2a specifications for a detailed explanation on
topology management, link count total, relative addressing, and side band messaging of MST
functionality.
Setup Details
Hardware Setup and Run
1. Connect the Tokyo Electron Device Limited (TED) TB-FMCH-DP2 module to the HPC FMC
connector on the KC705 board.
2. Connect a USB cable (Type A to mini B) from the host PC to the USB UART port on the KC705
for serial communication.
3. Connect a JTAG USB Platform cable or a USB Type A to Micro B cable from the host PC to the
KC705 board for programming bit and elf files. (In this setup a JTAG Platform cable is used.)
4. Connect a DP cable from the TX port of the TED TB-FMCH-DP-2 module to a monitor, as
shown in Figure 6.
