While we have supported MrsP for quite some time, there are certainly several kinds of multiprocessor protocols. I wonder if we need to have a roadmap and plan to make sure we are being thoughtful about how we accept these as they commit us to API. In this case, the attribute field becomes something we have to support into the future. -- View it on GitLab: https://gitlab.rtems.org/rtems/rtos/rtems/-/merge_requests/882#note_148517 You're receiving this email because of your account on gitlab.rtems.org.
