This is going to be a big one.  We're at version 2.5 and we're going to go to 2.9.3.

RCG components that need to be updated:

  • mbuf kernel module
  • mx_stream driver
  • iniChk.pl script
  • daqd
  • nds

Supporting software:

  • EPICS 3.14.12.2_long
  • ldas-tools (framecpp) 1.19.32-p1
  • libframe 8.17.2
  • gds 2.16.3.2
  • fftw 3.3.2

Things to watch out for:

  • RTS 2.6:
    • raw minute trend frame location has changed (CRC-based subdirectory)
    • new kernel patch
  • RTS 2.7:
    • supports "commissioning frames", which we will probably not utilize.  need to make sure that we're not writing extra frames somewhere
  • RTS 2.8:
    • "slow" (EPICS) data from the front-end processes is acquired via DAQ network, and not through EPICS.  This will increase traffic on the DAQ lan.  Hopefully this will not be an issue, and the existing network infrastructure can handle it, but it should be monitored.
