Add front end recovery to AMC configure action

Mykhailo Dalchenko requested to merge feature/detector-cold-start into develop


Add front end recovery procedure to ensure proper cold start operation. This is temporary measure as multiple things would be updated in future. Current iteration of code relies on existing functionality under gemrpc, the only change is a bugfix in the daq monitor code. Perhaps we will want to rearrange things in future. The functionality approximately implements a diagram discussed in #11 (closed) at the level of AMC manager. It performs:

  • GBT link reset
  • Retrieves status information for all possible GBT links of the system (thus, does not rely on supplied configuration)
  • Reprograms GBTs on optical links where all GBTs are locked (so non-powered or non-connected links are ignored)
  • Performs SCA reset on those active optical links
  • Issues internal Hard Reset to program FPGAs

How Has This Been Tested?

Tested in private installation on gem904daq04 with coffin setup. Note that additional env variable pointing to the location of GBT configuration files is required now. Corresponding snippet has been updated.
