Preston Faiks commented: https://gitlab.rtems.org/rtems/rtos/rtems/-/issues/5214#note_120103 Thread-level (rather than system-level) is done by multiple other rtems BSPs. For example [Sparc](https://gitlab.rtems.org/rtems/rtos/rtems/-/blob/main/cpukit/score/cpu/sparc/cpu_asm.S?ref_type=heads#L738) and [PowerPC](https://gitlab.rtems.org/rtems/rtos/rtems/-/blob/main/bsps/powerpc/shared/cpu_asm.S?ref_type=heads#L175). So this really isn't a new feature. I think the usefulness of this is unquestionably better than having applications save/restore state before every single function which might invoke a context switch. Many systems have a code base that is impractical to modify to such a large extent. -- View it on GitLab: https://gitlab.rtems.org/rtems/rtos/rtems/-/issues/5214#note_120103 You're receiving this email because of your account on gitlab.rtems.org.
