From 4686554260a89ab1127d0583d5636df4174bc813 Mon Sep 17 00:00:00 2001 From: Sebastian Huber Date: Sat, 7 Dec 2019 12:06:01 +0100 Subject: rtems: Simplify semaphore configuration 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.
