Experimental Physics and
Industrial Control System

I'm looking to collect some feedback from you all related to
EPICS+RTEMS. I'm trying to also keep in touch with monitoring the
progress on EPICS7/RTEMS5 (And, I'm planning to participate with
students in the upcoming hackathon! if you have tasks related, I might
be able to help knock them out). My ask right now is:
* What feature improvements would you like to see in future RTEMS releases?
* What are your pain points with current RTEMS versions and/or workflows?

And anything else positive/negative you'd like to put out here is
certainly welcome.

One feature that I know my IT department is looking forward to is an NFSv3/NFSv4 client, which I know has been funded. I was concerned when this was described as being for RTEMS-6 so I would be interested in the changes that have been made to the release numbering scheme since RTEMS-5, and when RTEMS-6 is likely to be released. I just found and read this so it doesn’t look like you’re using Semantic Versioning (but neither is EPICS).

Progress on our RTEMS-5 port of EPICS Base can be followed at this GitHub PR.

I suspect Michael’s question about the VMEbus driver may have come from a possibly misleading comment in one of the build configuration files for new RTEMS-5 target in the above PR. When talking to VMEbus devices EPICS needs the memory probing routines found in Till Strauman’s rtems-libbspExt module which I understand is not an official part of RTEMS and has not been ported to use the Posix APIs. My group will need EPICS and VMEbus support for RTEMS-5 on the qoriq_e500 BSP (MVME2500 board) within a few months, so we’re interested in any news about plans to merge or replace Till Strauman’s module. We will have someone who can work on and/or test this if necessary
