Redhat Linux - Magma EB7-X8G2 User Manual

Magma

RedHat Linux

Once the EB7-X8G2 has been installed in a RedHat9-based system, its installation can be verified by typing the following
command lines:
lspci –t Displays the overall structure of the PCIe expansion system
lspci –vv Lists additional information about the PCIe switch (in our case it will list the Integrated Device Technology (IDT)
information.
Ispci –vvv Displays the most comprehensive information about the expansion system.
Typical output from lspci –vvv is verbose, but you can dig through the information to find very important information.
There are so many registers and settings associated with PCI Express Switches.
Use the "lspci -vvv| grep "IDT" command to check that the Magma card and slot devices are detected (see image
below). IDT is the PCIe switch (component) on the Magma expansion board.
You can alsouse the "lspci –vvv | grep "807". The vendor ID for IDT PCie switch is 8077
The first PCI Bridge in this example is the Upstream Port. The 'Downstream" ports are the remaining are the PCIe slots.
