We propose to export DAQ:NEH:tmo (read-only) from the tmo gateway.  This is for variables like DAQ:NEH:tmo:0:DeadFrac created by the prom2pvs process.  We also export DAQ:NEH:XPM (read-write) from the drp gateway so that control-level processes running on machines like tmo-daq can program XPM's.

On April 15, 2024 the drp gateway exposed DAQ:NEH:* and DRP:*, we will try removing these on April 22, 2024.  There is also a DET:*, which we should try to remove as well on April 22, 2024.

There are special rules that are read-write from DRP:

mcc-daq.pvlist:EM1K0:GMD:HPS:BLD:PAYLOAD           ALLOW RWDRP
mcc-daq.pvlist:EM2K0:XGMD:HPS:BLD:PAYLOAD          ALLOW RWDRP
rix.pvlist:RIX:TIMETOOL:.*      ALLOW RWDRP 1
rix.pvlist:MR4K2:FIM:W8:.* ALLOW RWDRP 1
rix.pvlist:MR3K2:FIM:W8:.* ALLOW RWDRP 1
rix.pvlist:RIX:FIM:W8:03.* ALLOW RWDRP 1
rix.pvlist:RIX:CRIX:W8:.* ALLOW RWDRP 1
tmo.pvlist:DAQ:TMO:HSD:1_DA.*    ALLOW  RWDRP   1
tmo.pvlist:TMO:TIMETOOL:.*      ALLOW RWDRP 1
tmo.pvlist:MR2K4:FIM:W8:.* ALLOW RWDRP 1
tmo.pvlist:MR3K4:FIM:W8:.* ALLOW RWDRP 1
txi.pvlist:TXI:TIMETOOL:.*      ALLOW RWDRP 1

also this one for the tmo laser wave8:
las-amo.pvlist:LM1K4:W8:04:.*                ALLOW RWTMODAQ 1

cpo thoughts:

• gmd/xgmd should be removed, but I will confirm with the group
• RIX:RIM:W8 is old and should be removed (replaced by CRIX wave8)
• don't understand the TIMETOOL ones, but may be necessary.  cpo will think.

When we make the changes, we will check:

• the daq runs
• grafana works
• TIMETOOL still works
