17:19 Changeset in rtems [a857a22] by Kinsey Moore <kinsey.moore@…>
cpukit/aarch64: Add libdebugger support This adds support for libdebugger under AArch64 using software breakpoints and the single-step execution mode present in all AArch64 CPUs.
16:03 Changeset in rtems [75c133bd] by Sebastian Huber <sebastian.huber@…>
sptests/sp69: Remove test case This error condition no longer exists. Update #4528.
14:56 Changeset in rtems [750bde8] by Kinsey Moore <kinsey.moore@…>
bsps/aarch64: Mask debug events from startup Debug events should be masked at least until after the first context switch and should usually be masked until a debugger is attached for application debugging.
14:53 Changeset in rtems [2d27725] by Kinsey Moore <kinsey.moore@…>
bsps/aarch64: Set interrupt level correctly The existing code is functional but inccorrect and blindly modifies the other masking bits. It is important to preserve those other bits since they control masking of important system events.
14:50 Changeset in rtems [55a93ae] by Kinsey Moore <kinsey.moore@…>
bsps/aarch64: Add missing MMU map recursion check Certain input parameters for MMU mapping operations could cause an infinite recursion if block end boundaries didn't align to 4k. This ensures that recursion descent does not exceed 2 levels and instead rounds up to the nearest 4k block if necessary.
14:47 Changeset in rtems [2055e42] by Kinsey Moore <kinsey.moore@…>
aarch64: Break out MMU definitions This moves the AArch64 MMU memory type definitions into cpukit for use by libdebugger since remapping of memory is required to insert software breakpoints.

12:21 Changeset in rtems [ff20bc9] by Sebastian Huber <sebastian.huber@…>
score: Rework idle handling in SMP schedulers This patch fixes an issue with the idle thread handling in the SMP scheduler framework used for the MrsP locking protocol. The approach to use a simple chain of unused idle threads is broken for schedulers which support thread to processor affinity. The reason is that the thread to processor affinity introduces another ordering indicator which may under certain conditions lead to a reordering of idle threads in the scheduled chain. This reordering is not propagated to the chain of unused idle threads. This could lead to use an idle thread for a sticky scheduler node which is already in use. This locks up the system in infinite loops in the thread context switch procedure. To fix this, the SMP scheduler implementations must now provide callbacks to get and release an unused idle thread. Update #4531.

timecounter: Lock the timecounter list Timecounter registration is dynamic, i.e., there is no requirement that timecounters must be registered during single-threaded boot. Loadable drivers may in principle register timecounters (which can be switched to automatically). Timecounters cannot be unregistered, though this could be implemented. Registered timecounters belong to a global linked list. Add a mutex to synchronize insertions and the traversals done by (mpsafe) sysctl handlers. No functional change intended.

09:21 Changeset in rtems [3d6ebde1] by Sebastian Huber <sebastian.huber@…>
score: Add SMP scheduler make/clean sticky This patch fixes the following broken behaviour: While a thread is scheduled on a helping scheduler, while it does not own a MrsP semaphore, if it obtains a MrsP semaphore, then no scheduler node using an idle thread and the ceiling priority of the semaphore is unblocked for the home scheduler. This could lead to priority inversion issues and is not in line with the MrsP protocol. Introduce two new scheduler operations which are only enabled if RTEMS_SMP is defined. The operations are used to make the scheduler node of the home scheduler sticky and to clean the sticky property. This helps to keep the sticky handing out of the frequently used priority update operation. Close #4532.

rtems: Fix rate monotonic statistics The rate monotonic period statistics were affected by rtems_cpu_usage_reset(). The logic to detect and work around a CPU usage reset was broken. The Thread_Contol::cpu_time_used is changed to contain the processor time used throughout the entire lifetime of the thread. The new member Thread_Contol::cpu_time_used_at_last_reset is added to contain the processor time used at the time of the last reset through rtems_cpu_usage_reset(). This decouples the resets of the CPU usage and the rate monotonic period statistics. Update #4528.
