But I don't think we should fail silently in this case since the software map will not be representative of the hardware one. Note that when _writing_ to the mapping registers, each value is bounded using a modulo of the maximum bus interrupt line in the system. So on the GR740, writing 33 to one of the fields will result in a mapping to interrupt line 1. -- View it on GitLab: https://gitlab.rtems.org/rtems/rtos/rtems/-/merge_requests/1514#note_160070 You're receiving this email because of your account on gitlab.rtems.org.
