2:37 PM Changeset in rtems [ddbc3f8d]4.11 by Daniel Cederman <cederman@…>
score: Add SMP support to the cache manager Adds functions that allows the user to specify which cores that should perform the cache operation. SMP messages are sent to all the specified cores and the caller waits until all cores have acknowledged that they have flushed their cache. If CPU_CACHE_NO_INSTRUCTION_CACHE_SNOOPING is defined the instruction cache invalidation function will perform the operation on all cores using the previous method.

score/sparc: Add comment on icache flush after trap table update Changes to the trap table might be missed by other cores. If the system state is up, the other cores can be notified using SMP messages that they need to flush their icache. If the up state has not been reached there is no need to notify other cores. They will do an automatic flush of the icache just after entering the up state, but before enabling interrupts. Cache invalidation is required for both single and multiprocessor systems.

score: Scheduler helping proto for affinity sched The priority affinity scheduler has the nice property that it can produce more than one scheduled to ready state change in one operation. Each scheduled to ready state change may lead to one thread in need for help. Since it is currently only possible to return at most one thread in need for help, we have a problem here. A solution might be to move the check for migrations into the ask for help mechanism.

7:20 PM Changeset in rtems [b6343c6]4.11 by Joel Sherrill <joel.sherrill@…>
Enhance Semaphore Blocking and Readying Time Test Cases tm02 and tm03 were modified to be reused for multiple configurations of RTEMS Classic API Semaphores. This added tm31-36. The messages for tm02 and tm03 were modified to indicate the semaphore attributes. tm31 - tm36 were added. This resulted in the following cases: tm02 - rtems_semaphore_obtain: Counting/FIFO not available caller blocks tm03 - rtems_semaphore_release: Counting/FIFO task readied preempts caller tm31 - rtems_semaphore_obtain: Counting/priority not available caller blocks tm32 - rtems_semaphore_release: Counting/priority task readied preempts caller tm33 - rtems_semaphore_obtain: Binary/FIFO not available caller blocks tm34 - rtems_semaphore_release: Binary/FIFO task readied preempts caller tm35 - rtems_semaphore_obtain: Binary/priority not available caller blocks tm36 - rtems_semaphore_release: Binary/priority task readied preempts caller

12:34 PM Changeset in rtems [5c3d250]4.11 by Sebastian Huber <sebastian.huber@…>
score: Implement scheduler helping protocol The following scheduler operations return a thread in need for help - unblock, - change priority, and - yield. A thread in need for help is a thread that encounters a scheduler state change from scheduled to ready or a thread that cannot be scheduled in an unblock operation. Such a thread can ask threads which depend on resources owned by this thread for help. Add a new ask for help scheduler operation. This operation is used by _Scheduler_Ask_for_help() to help threads in need for help returned by the operations mentioned above. This operation is also used by _Scheduler_Thread_change_resource_root() in case the root of a resource sub-tree changes. A use case is the ownership change of a resource. In case it is not possible to schedule a thread in need for help, then the corresponding scheduler node will be placed into the set of ready scheduler nodes of the scheduler instance. Once a state change from ready to scheduled happens for this scheduler node it may be used to schedule the thread in need for help.
