Loading the Gen-Z prototype subsystem into F.E.E.

This assumes you already have the Fabric Emulation Environment running and have created at least one virtual machine configured to join the emulated fabric. Those instructions given in the F.E.E. repo.

If the switch process is running, and you've started the VM, you should also see a description

Driverless QEMU

in one of the slots of the switch interface.

Log into VM and clone this repo

First, 'lspci -v' and insure you have the RedHat IVSHMEM pseudo device with 16 MSI-X interrupts.

Depending on how you built your VM, you may need to download additional packages like git, Linux headers for your kernel, build-essential, etc.

1. git clone https://github.com/linux-genz/EmerGen-Z.git
2. cd EmerGen-Z/subsystem
3. make all
4. make modules install
5. cd ../shim_driver
6. make all
7. make modules install

Now try

sudo modprobe genz_fee

Two modules should load and the description in the switch window should change. There should also be about twenty genz entries under /sys/class.

A third module is needed for the actual bridge driver:

sudo modprobe genz_fee_bridge

Insure there is a device file /dev/genz_fee_bridgeXX.

Messages are sent with

echo "CID,SID:the message" > /dev/genz_fee_bridgeXX

If the CID,SID is not assigned (to be documented SOON) then you can use a single digit to target the emulated fabric index.

"cat < /dev/famez_bridgeXX" to read data.
