Does any RTOS support SMP scheduling?


We have a project in which the SOC has multi-core like ARM Cortex-R8; so we want an open-source RTOS that supports SMP scheduling. But it seems that no RTOS supports SMP, at least from its official release version.

Could anyone give the suggestion about it?


Solution

  • It is neither true that no RTOS has SMP support, or even that no open-source RTOS has support.

    The open-source eCOS supports SMP (Symmetric Multiprocessing). http://ecos.sourceware.org/docs-3.0/ref/kernel-smp.html

    Also NuttX http://nuttx.org/doku.php?id=wiki:nxinternal:smp

    In the non open-source world, choices are wider, such as QNX Neutrino, and VxWorks.
