------------------------------+-----------------------------
In SMP configurations, the maximum count of MrsP semaphores must be
configured via CONFIGURE_MAXIMUM_MRSP_SEMAPHORES. The MrsP semaphore
implementation predates the addition of self-contained synchronization
objects. At this time, the potential memory reduction was justified
considering the more complex configuration and additional use of the
workspace. With the availability of self-contained synchronization
options, e.g. POSIX mutexes, this is no longer justified. Memory
constrained applications should use the self-contained synchronization
objects. Remove the CONFIGURE_MAXIMUM_MRSP_SEMAPHORES configuration
option. This has only an impact on applications which use SMP and a large
number of scheduler instances.
