Port from VxWorks to OSI

• Kay Kasemir supportive nice collaboration
• Most work in driver not device support
• Test on Unix first, then checkout on RTEMS
• Timing and semaphores most work
• Existing diagnostics great help, web interface
  useful
• Function registration for iocsh
• C considerations

5
Port from VxWorks to OSI (cont)

• Not much work for sockets add TCP_NODELAY
  option
• On RTEMS, may need to increase packet limit
  (max_interrupt_work) from 20 to 40
• connectWithTimeout is needed in osiSock!
• Change documentation a little

6
Share Source for 3.13/3.14?

• Use EPICS_VERSION and EPICS_REVISION, mostly in
  include files to set other macros (code more
  readable)
• Setup macros to make 3.13 look like 3.14
• Maintain both config and configure directories
  with the package
• Maintain both Makefile (3.14) and Makefile.Vx
  (3.13)
• Change Makefile to build 3.14 if EPICS_HOST_ARCH
  is set, otherwise 3.13
