LinuxRT Startup Scripts:

[cpu]/startup.cmd 

• A link to skel/startup_cpu.cmd or a real file. 

Calls $IOC/common/linuxRT_startup_cpu.sh to set up environment & hardware.

• If using a real file, optionally create a list of screenrc VIOCs to start up
• If using a real file, optionally create a list of the executables to start them with

Calls $IOC/common/linuxRT_cpu_load_viocs to start the listed VIOCs or extract the list from screeniocs

[cpu]/kernel-modules.cmd

• Called by $IOC/common/linuxRT_startup_cpu.sh to load kernel modules.
• Custom for each CPU. May contain other related commands.
  
  

$IOC/common/linuxRT_startup_cpu.sh

• Load environment
• mount nfs dir
• load kernel modules with [cpu]/kernel-modules.cmd
• start CA repeater
  
  

$IOC/common/linuxRT_cpu_load_viocs.sh

• If a list of IOCs to start up is defined as an environment variable, use it.
• Otherwise use screeniocs.
• If there is a list of executables in an environment variable to go with the list of IOCs, use it.
  
  

For each ioc, call linuxRT_startup_vioc.sh iocDirName epicsApp   ($IOC/common/linuxRT_startup_vioc.sh iocName [epicsApp])

• Set ulimits
• set umask
• cd to the vioc directory
• If the exececutable name was passed as the second argument, use that.
• Otherwise, check screeniocs to determine the epicsApp.
• Otherwise look for a #! at the top of ioc/startup.cmd to determine the epicsApp.
• Otherwise look for a #! at the top of ioc/iocSpecificRelease/iocBoot/[iocName]/st.cmd to determine the epicsApp.
• run startup.cmd using screen and epicsApp
