Advanced Bring-up with Base Targeted Reference Design
Using the Application GUI
The transmission and reception of data is configured through the application GUI. The
GUI displays collected statistics and other status information.
At startup, the GUI displays a launching page that detects the PCIe device for this design
(Vendor ID = 0x10EE and Device ID = 0x7042). When the appropriate device is detected,
driver installation is allowed to proceed. An additional option is available which allows
the enabling of a data integrity check. Upon successful installation of the drivers, the
control and monitoring interface appears.
GUI Control Function
These parameters are controlled with the GUI:
• Packet size for traffic generation.
•Test selection:
• Loopback
•HW checker
•HW Generator
GUI Monitor Function
The driver always maintains information about the hardware status. The GUI periodically
issues an I/O Control, ioctl(), to read the status information which is comprised of:
•PCIe link and device status
•DMA controller status
•Power status
The driver maintains a set of circular arrays to hold second-by-second sampling points of
various statistics which are periodically collected by the performance monitor handler.
The various GUI indicators and controls are detailed in Figure 25 and Table 5.
