FELIX drivers

From the installation folder we took the version recommended for Felix 5.1 (4.20.0) from the root account:

wget https://atlas-project-felix.web.cern.ch/atlas-project-felix/user/dist/software/drivers/latest/el9/felix-drivers-04-20-00/tdaq_sw_for_Flx-4.20.0-2dkms.noarch.rpm
dnf install tdaq_sw_for_Flx-4.20.0-2dkms.noarch.rpm

Everything worked as expected:

depmod
systemctl restart drivers_flx_sd

Everything looks OK:

[root@felix-1 ~]# cat /proc/flx

Command 'echo <action> > /proc/flx', executed as root,
allows for interaction with the driver. Possible actions are:
debug     -> Enable debugging
nodebug   -> Disable debugging
elog      -> Log errors to /var/log/message
noelog    -> Do not log errors to /var/log/message
clearlock -> Clear all lock bits (Attention: close processes that hold lock bits before doing this)
