From 7fe6d60bf08df975c395515074c85976d9e4e3fb Mon Sep 17 00:00:00 2001 From: Sebastian Huber Date: Fri, 15 Jul 2022 09:16:04 +0200 Subject: score: Remove PRIORITY_PSEUDO_ISR thread priority The uniprocessor schedulers had some special case logic for the PRIORITY_PSEUDO_ISR priority. Tasks with a priority of PRIORITY_PSEUDO_ISR were allowed to preempt a not preemptible task. If other higher priority task are made ready while a PRIORITY_PSEUDO_ISR task preempts a not preemptible task, then the other tasks run before the not preemptible task. This made the RTEMS_NO_PREEMPT mode ineffective. Remove the PRIORITY_PSEUDO_ISR special case logic. This simplifies the uniprocessor schedulers. Move the uniprocessor-specific scheduler support to the new header file .
