Note that ISI at Vanderbilt implemented an emulation library for ARINC on top of POSIX,
see https://wiki.isis.vanderbilt.edu/mbshm/index.php/ACMTOOLSUITE

(You need to be careful about what you build, a part of it drags the whole TAO middleware, be sure to test just the ARINC part)

it can be a first step towards supporting this API in RTEMS

a) first you port it. they support part of the standard. Partitions are mapped to Unix processes, a daemon activate/passivate process to support time isolation. One can certainly emulate similar behavior using a dedicated thread that change task proporties to enable/disable them

b) then the port work may start, following the overview proposed by Cláudio. Starting from this emulation library would help understanding in more depth the amount of work required.
