Previously, the _Thread_Heir was updated unconditionally in case a new heir was determined. The _Thread_Dispatch_necessary was only updated in case the executing thread was preemptible or an internal thread was unblocked. Change this to update the _Thread_Heir and _Thread_Dispatch_necessary only in case the currently selected heir thread is preemptible or a dispatch is forced. Move the schedule decision into the change priority operation and use the schedule operation only in rtems_task_mode() in case preemption is enabled or an ASR dispatch is necessary. This is a behaviour change. Previously, the RTEMS_NO_PREEMPT also prevented signal delivery in certain cases (not always). Now, signal delivery is no longer influenced by RTEMS_NO_PREEMPT. Since the currently selected heir thread is used to determine if a new heir is chosen, non-preemptible heir threads currently not executing now prevent a new heir. This may have an application impact, see change test tm04. Document this change in sp04. Update #2273.
This is the directory under which the RTEMS
test programs provided with the release are located. The
following is a description of the contents of each file and
subdirectory directly in this directory:
NOTE: Other than the 'samples' directory these tests are intended
only to exercise RTEMS features and are *not* good examples
of programming for RTEMS.
samples
This directory contains a set of simple sample applications
which can be used either to test a board support package
or as the starting point for a custom application.
mptests
This directory contains the RTEMS Multiprocessor Test Suite.
The tests in this directory provide near complete (98%+) test
coverage of the multiprocessor specific code in RTEMS.
psxtests
This directory contains the RTEMS POSIX API Test Suite.
The tests in this directory test the POSIX API support in RTEMS.
sptests
This directory contains the RTEMS Single Processor Test Suite.
The tests in this directory provide near complete (98%+) test
coverage of the non-multiprocessor code in RTEMS.
tmtests
This directory contains the RTEMS Timing Test Suite.
The tests in this directory are used to measure the execution
time of RTEMS directive and some critical internal functions.
The results of these test are reported in the Fact Sheets
and Supplental Manuals.
