Setting up the IpBus Code¶
This will only work on machines that have SLF6 or SLC6 installed. We have tried it successfully with both these Linux variants.
We have done this in two steps.
1. As root install the IpBus and dependent rpms and their automatic updates.
2. As any user creating an area which has all the static IpBus files required.
We don't know whether 2. works without first doing 1. since the IPbus install also installs some other RPMs (e.g. zlib-devel ncurses-devel etc) that it needs. However you need only do step 1 once and then you can use the static version of IPBus in step 2. By using a static version of the IpBus code we then don't build against code that is changing via nightly yum updates from CERN. We have scripts in the repository and running under cron monitoring these updates with respect to the static version and we also have a script svn checking out the latest IpBus source code to monitor for significant VHDL code changes. As it stands we are presently building all our code against the version of IpBus from 24/10/2013.
Step-1 : Install the IpBus rpms¶
Depends on system type : either x86_64:
sudo cp cactus.slc6.x86_64.repo /etc/yum.repos.d/cactus.repo
sudo cp cactus.slc6.i686.repo /etc/yum.repos.d/cactus.repo
sudo yum groupinstall uhal@
This installs the IpBus libraries in /opt/cactus and the system libraries needed by IpBus. These are then updated via nightly yum updates. We have chosen however to build our code against a fixed IpBus version which in installed in Step 2 below.
To double check that all external dependencies are installed also do:
sudo yum -u install bzip2-devel zlib-devel ncurses-devel python-devel curl curl-devel graphviz graphviz-devel qt qt-devel PyQt PyQt-devel wxPython
sudo yum install PyQt qt* *-qt*
Particularly PyQt is needed for the graphical run-control interface.
Step-2 : Install the fixed / static IpBus code¶
Create an appropriate directory for the code. In the following we will assume this is: /data/g-2/.
mkdir -p $GM2_ROOT/cactus/24_10_2013
tar -xzf cactus-24_10_2013.tgz
This installs all the IpBus files (headers, libraries and executables) that we will need in $GM2_ROOT/cactus/24_10_2013
Install the google-test suite¶
mkdir -p $GM2_ROOT/gtest
tar -xzf gtest-1.7.0.tgz
ln -sf gtest-1.7.0 latest
This installs the google-test suite in $GM2_ROOT/gtest/latest
Install a compatible version of ROOT¶
This may already be present but you need to make sure your version of ROOT is compiled with the same compiler you'll be using with the IpBus and readout code. IpBus and the readout is compiled against the default SLF6/SLC6 compiler i.e. gcc_v4.4.7. The following steps will build v5.30.06 of ROOT.
tar -xvzf root_v5.30.06.source.tar.gz
mv root root_v5.30.06_gcc_v4.4.7
ln -sf root_v5.30.06_gcc_v4.4.7 root
This will install ROOT in $GM2_ROOT/root
Setup a local copy of the git repository¶
For more details see here
But the essential steps are:
Get a kerberos ticket:
kinit -f username@FNAL.GOV
Then you need only do this ONCE to get a local copy of the repository:
git clone ssh://firstname.lastname@example.org/cvs/projects/gm2-tracker-readout-daq
git config --global user.name "Your name"
git config --global user.email email@example.com
git remote rename origin fnal
These are then the commands you will use frequently:
git checkout develop
Switch to develop branch: Note all the most recent code is in the "develop" branch and so this is the version of the code to work with
git pull fnal develop
Get the latest code from the FNAL repository (develop branch) into the local repository (develop branch)
git add file
Add a file to the local repository:
git commit -m "blah" file
Commit a file/change to the local repository:
git push fnal develop
Send the changes from your local repository to the FNAL repository so that others can use them:
Using and compiling IpBus code¶
git checkout develop
Edit the setup file: trackerDaq-setup.sh
You should add the node you are running on that has the IpBus software installed such that you will then get a warning if you attempt to run on another node. You should also make sure that GM2_ROOT is setup appropriately.
Having edited this file, setup the environment:
source ./trackerDaq-setup.sh [or] . ./trackerDaq-setup.sh
Build the C++/python code
The "make" without a target runs the header dependency generation step by default. This can take 30 secs or so. If you've done a "make" once without a target you can generally skip this unless you've added new code. And so:
just does the compiling and linking using the existing dependency files.
The VHDL for the ATLYS board is from two sources:
1. The repository directory: hardware/trm/firmware/vhdl i.e. the folder $GM2_ROOT/gm2-tracker-readout-daq/hardware/trm/firmware/vhdl
2. The repository directory: cactus/trunk/components/ipbus/firmware/ipbus_core/hdl i.e. the folder $GM2_ROOT/gm2-tracker-readout-daq/cactus/trunk/components/ipbus/firmware/ipbus_core/hdl
This is the VHDL that is loaded onto the Digilent ATLYS.
We have tested this against the TDC firmware from the BU page that we have installed on an ALTERA DE0.
The IpBUS configuration file¶
The file is in the repository as the file: software/cfg/connections.xml
This defines the IP addresses that the ATLYS boards have and the name we are using for the boards. In this case we have one ATLYS board
called "Board1" at 188.8.131.52 and one called "Board2" at 184.108.40.206.
This configuration file also defines the location of the XML file that has the actual address map for the ATLYS VHDL - this in the repository as software/cfg/atlys_board_address_table_trm.xml
Note the syntax for specifying this files is "file:///xxx" for a file at "/xxx"
Running some example code¶
Having downloaded the VHDL onto the ATLYS and TDC/DE0 board then the following executables can be run to test the boards.
bin/Register_RW.exe cfg/connections.xml Board1 control_0.run_mode W 31
bin/Register_RW.exe cfg/connections.xml Board1 control_0.run_mode R
The last two commands write 0x31 to the run_mode register of the control_0 block and then read it back. These are defined in the software/cfg/atlys_board_address_table_trm.xml file.
bin/test_TrackerDaqRoot.exe < cfg/test_TrackerDaqRoot.cards
This writes to the registers, generates start of spill commands and reads fake data from the TDC via the ATLYS and puts it into a ROOT file.
cfg/test_TrackerDaqRoot.cards steers the execution of the code e.g. it defines the location of the connections.xml file, which ATLYS board we are talking to and the number of fake spills to generate.
There is a also a Python GUI run-control invoked via: python Gm2RunControlGUI.py
