Chris Johns commented on a discussion: https://gitlab.rtems.org/rtems/rtos/rtems/-/issues/5214#note_119871 There is a distinction within a context switch of being preempted or blocking and switching. Block requires you make a call to something that blocks. It could a read type call or a timer call.\ \ If I understand the spec the register in question is not saved across calls so I could set the register's value `X` and make a call and it can return with value `Y`. Blocking means making a call so the state is not preserved. If preempted it must be preserved. -- View it on GitLab: https://gitlab.rtems.org/rtems/rtos/rtems/-/issues/5214#note_119871 You're receiving this email because of your account on gitlab.rtems.org.
