In this section, a detailed description of the IOC bootup process is laid out.
First, define the usual environment variables in the startup script.
Code Block | ||
---|---|---|
| ||
# =========================================== # ENVIRONMENT VARIABLES # =========================================== epicsEnvSet("AREA", "SYS0" ) epicsEnvSet("UNIT", "MS09" ) epicsEnvSet("LOCATION", "" ) epicsEnvSet("IOC_PV", "SIOC:$(AREA):$(UNIT)" ) epicsEnvSet("TPR_PV", "TPR:$(AREA):$(UNIT)" ) epicsEnvSet("IOC", "sioc-sys0-ms09" ) epicsEnvSet("HASH", "58070ee" ) epicsEnvSet("YAML_DIR", "${TOP}/yaml/EvrCardG2-$(HASH).yaml") epicsEnvSet("YAML_TOP_FILE", "${YAML_DIR}/000TopLevel.yaml" ) # Support Large Arrays/Waveforms; Number in Bytes epicsEnvSet("EPICS_CA_MAX_ARRAY_BYTES", "2000000") |
Load dbd and IOC health/monitoring records. Also, set up autosave and load the LCLS access configuration file. Finally, copy the archive file in $IOC_DATA to enable record archiving.
Code Block | ||
---|---|---|
| ||
## Load dbd dbLoadDatabase("dbd/masterSource.dbd", 0, 0) masterSource_registerRecordDeviceDriver(pdbbase) ## Environment variables epicsEnvSet("ENGINEER", "") epicsEnvSet("STREAM_PROTOCOL_PATH", "${TOP}/db") ## Tag log messages with IOC name epicsEnvSet("EPICS_IOC_LOG_CLIENT_INET", "${IOC}") ## Load records # **** Load iocAdmin databases to support IOC Health and monitoring **** dbLoadRecords("db/iocAdminSoft.db", "IOC=${IOC_NAME}") dbLoadRecords("db/iocAdminScanMon.db", "IOC=${IOC_NAME}") dbLoadRecords("db/iocRelease.db", "IOC=${IOC_NAME}") ## Autosave initialization < $(TOP)/iocBoot/common/autosave_init.cmd ## Channel Access Security: # This is required if you use caPutLog. # Set access security file # Load common LCLS Access Configuration File < ${ACF_INIT} ## Update archive pv list in ${IOC_DATA} system("cp $(TOP)/archive/${IOC}.archive ${IOC_DATA}/${IOC}/archive/") |
Tell the IOC where to find the list of record names and where they will be autosaved. Also, restore previously autosaved values.
Code Block | ||
---|---|---|

Besides the auto-generated record names for autosave, copy the manually generated list of records to be autosaved and restore their previously autosaved values.
Code Block | ||
---|---|---|
| ||
# Copy over the manual settings request file system("cp $(TOP)/autosave/${IOC}.req ${IOC_DATA}/${IOC}/autosave-req/") # Load manual settings from autosave set_pass0_restoreFile("${IOC}.sav") set_pass1_restoreFile("${IOC}.sav") |
Load the YAML hierarchy and register configuration.
Code Block | ||
---|---|---|
| ||
# Use slot A pcie tpr for root_0, override to use slot_a cpswLoadYamlFile("${YAML_TOP_FILE}", "MemDev", "", "/dev/tpra", "root_0") |
Load the phase locker records.
Code Block | ||
---|---|---|
| ||
# =========================================== # DB LOADING # =========================================== # TPR driver DB dbLoadRecords("db/pcie_tprTrig.db", "DEV=${IOC_PV}:0,LOCA=$(AREA),IOC_UNIT=$(UNIT),INST=0,PORT=trig0") # Load database for autosave status dbLoadRecords("db/save_restoreStatus.db", "P=${IOC_PV}:") |
Create the ycpswAsynDriver with a dictionary option, i.e. use a limited number of interfaces to the FPGA registers.
Code Block | ||
---|---|---|
| ||
# =========================================== # DRIVER SETUP # =========================================== # Configure crossbarControlAsynDriver crossbarControlAsynDriverConfigure("crossbar0", "PCIe:/mmio/SfpXbar", "root_0") # Setup tprTrigger Driver tprTriggerAsynDriverConfigure("trig0", "PCIe:/mmio", "root_0") |

To set the triggers and corresponding channels in Production, follow the instructions below.
Code Block | ||
---|---|---|
| ||
[softegr@lcls-srv01 skoufis]$ cd $EPICS_IOCS/sioc-sys0-ms09/iocSpecificRelease/masterSourceApp/srcDisplay/ [softegr@lcls-srv01 srcDisplay]$ ./sioc-sys0-ms09_gui.sh |
This should launch the main display, from which we can invoke the needed channel and trigger screens for setup. See an example of those scenes below.
To access and launch the display in Production, follow the steps outlined below.
The released software will be made available in the main IOC release area post-deployment (Dev: /afs/slac/g/lcls/epics/iocTop/masterSource/, Production:/usr/local/lcls/epics/iocTop/masterSource/). See below for the specific repositories and tags.
See software release details below.
