Port from vxworks to osi

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

EPICS Meeting June, 2003


Port from vxworks to osi cont

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

Share source for 3 13 3 14

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
