New optimizations: * align to 32-byte cache line. * rearrange code into three "blocks" of 4 instructions that is executed by syscall 2 and 3. This is to optimize for 16/32 byte cache lines. * use delay-slot instruction in trap table to reduce by one instruction. * use the fact that "wr %PSR" implements XOR to reduce by one instruction.

01:44 Changeset in rtems [b3fb2ff]4.115 by Chris Johns <chrisj@…>
bsp/gdbarmsim: Change syscall functions to not clash with RTEMS functions. The syscall functions overlapped with RTEMS, for example _write, _read, etc. Change these to be internal to the BSP and avoid any clash with names in RTEMS. Add support for SWI_Write0. Change the console driver to use SWI_Write0. This outputs the character to the host's stdout. Writing to file name 0 is not captured and managed by GDB's simulation code while the SWI_Write0 is. The managed stdout data is encapulated in the MI protocol while writes to file handle 0 are dropped by GDB when in MI mode.

It is currently not possible to test these fatal errors. One option would be to fake values of the _CPU_SMP_Get_current_processor(), but unfortunately this function is inline on some architectures.

SMP: make IPI fatal code unique The same smp fatal code is used in percpu _Per_CPU_State_change(). In order to determine which CPU requested a fatal shutdown and which CPU responds to it a unique code should be used. A unique code makes it also possible to handle the CPUs differently in the fatal exception handler.

The owner and rivals are impersonated via resource nodes. A resource is represented via the resource control structure. The resource controls and nodes are organized as trees. It is possible to detect deadlocks via such a resource tree. The _Resource_Iterate() function can be used to iterate through such a resource tree starting at a top node.

score: Multiprocessor Resource Sharing Protocol Add basic support for the Multiprocessor Resource Sharing Protocol (MrsP). The Multiprocessor Resource Sharing Protocol (MrsP) is defined in A. Burns and A.J. Wellings, A Schedulability Compatible Multiprocessor Resource Sharing Protocol - MrsP, Proceedings of the 25th Euromicro Conference on Real-Time Systems (ECRTS 2013), July 2013. It is a generalization of the Priority Ceiling Protocol to SMP systems. Each MrsP semaphore uses a ceiling priority per scheduler instance. These ceiling priorities can be specified with rtems_semaphore_set_priority(). A task obtaining or owning a MrsP semaphore will execute with the ceiling priority for its scheduler instance as specified by the MrsP semaphore object. Tasks waiting to get ownership of a MrsP semaphore will not relinquish the processor voluntarily. In case the owner of a MrsP semaphore gets preempted it can ask all tasks waiting for this semaphore to help out and temporarily borrow the right to execute on one of their assigned processors. The help out feature is not implemented with this patch.

LEON3: use CPU_Fatal_halt for halt By removing the bsp_reset() mechanism and instead relying on the CPU_Fatal_halt() routine SMP and single-core can halt by updating the _Internal_errors_What_happened structure and set the state to SYSTEM_STATE_TERMINATED (the generic way). This will be better for test scripts and debugger that can generically look into why the OS stopped. For SMP systems, only the fatal-reporting CPU waits until all other CPUs are powered down (with a time out of one clock tick). The reason why a fatal stop happend may be because CPU0 was soft-locked up so we can never trust that CPU0 should do the halt for us.

SPARC: Fatal_halt use source and exit codes The Fatal_halt handler now have two options, either halt as before or enter system error state to return to debugger or simulator. The exit-code is now also propagated to the debugger which is very useful for testing. The CPU_Fatal_halt handler was split up into two, since the only the LEON3 support the CPU power down. The LEON3 halt now uses the power-down instruction to save CPU power. This doesn't stop a potential watch-dog timer from expiring.

20:26 Changeset in rtems [238629f]4.115 by Joel Sherrill <joel.sherrill@…>
Add SMP Priority Scheduler with Affinity This scheduler attempts to account for needed thread migrations caused as a side-effect of a thread state, affinity, or priority change operation. This scheduler has its own allocate_processor handler named _Scheduler_SMP_Allocate_processor_exact() because _Scheduler_SMP_Allocate_processor() attempts to prevent an executing thread from moving off its current CPU without considering affinity. Without this, the scheduler makes all the right decisions and then they are discarded at the end. ==Side Effects of Adding This Scheduler== Added Thread_Control * parameter to Scheduler_SMP_Get_highest_ready type so methods looking for the highest ready thread can filter by the processor on which the thread blocking resides. This allows affinity to be considered. Simple Priority SMP and Priority SMP ignore this parameter. + Added get_lowest_scheduled argument to _Scheduler_SMP_Enqueue_ordered(). + Added allocate_processor argument to the following methods: - _Scheduler_SMP_Block() - _Scheduler_SMP_Enqueue_scheduled_ordered() - _Scheduler_SMP_Enqueue_scheduled_ordered() + schedulerprioritysmpimpl.h is a new file with prototypes for methods which were formerly static in schedulerprioritysmp.c but now need to be public to be shared with this scheduler. NOTE: _Scheduler_SMP_Get_lowest_ready() appears to have a path which would allow it to return a NULL. Previously, _Scheduler_SMP_Enqueue_ordered() would have asserted on it. If it cannot return a NULL, _Scheduler_SMP_Get_lowest_ready() should have an assertions.

13:07 Changeset in rtems [b9d871f9]4.10 by Chris Johns <chrisj@…>
rtems-test-check: Ignore tests which require real ISR based clock tick BSPs for simulators which do not include a clock tick interrupt source are incapable of running some tests successfully. This is a common characteristic of some BSPs and a fixed set of tests. There is no point in duplicating this list of tests in those BSPs test configuration.

11:50 Changeset in rtems [f39f667a]4.115 by Sebastian Huber <sebastian.huber@…>
score: Simplify _Thread_Change_priority() The function to change a thread priority was too complex. Simplify it with a new scheduler operation. This increases the average case performance due to the simplified logic. The interrupt disabled critical section is a bit prolonged since now the extract, update and enqueue steps are executed atomically. This should however not impact the worst-case interrupt latency since at least for the Deterministic Priority Scheduler this sequence can be carried out with a wee bit of instructions and no loops. Add _Scheduler_Change_priority() to replace the sequence of - _Thread_Set_transient(), - _Scheduler_Extract(), - _Scheduler_Enqueue(), and - _Scheduler_Enqueue_first(). Delete STATES_TRANSIENT, _States_Is_transient() and _Thread_Set_transient() since this state is now superfluous. With this change it is possible to get rid of the SCHEDULER_SMP_NODE_IN_THE_AIR state. This considerably simplifies the implementation of the new SMP locking protocols.

bsps/sparc: Fix BSS initialization Use bss_start available via %g2 to clear the BSS section. The usage of _edata resulted in a copy of [_edata, bss_start) from ROM to RAM and then a clear to zero of this area. Clear now only [bss_start, _end).
08:23 Changeset in rtems [b2d191e]4.115 by Sebastian Huber <sebastian.huber@…>
bsps/sparc: Fix data copy in start procedure Use the register %g4 for the data content since it must be an even numbered register due to the std/ldd. Use the register %g2 for the BSS start address, so that it can be later re-used for the BSS zero loop.
