8:58 AM Changeset in rtems [2f6108f9]4.11 by Sebastian Huber <sebastian.huber@…>
smp: Simplify SMP initialization sequence Delete bsp_smp_wait_for(). Other parts of the system work without timeout, e.g. the spinlocks. Using a timeout here does not make the system more robust. Delete bsp_smp_cpu_state and replace it with Per_CPU_State. The Per_CPU_State follows the Score naming conventions. Add _Per_CPU_Change_state() and _Per_CPU_Wait_for_state() functions to change and observe states. Use Per_CPU_State in Per_CPU_Control instead of the anonymous integer. Add _CPU_Processor_event_broadcast() and _CPU_Processor_event_receive() functions provided by the CPU port. Use these functions in _Per_CPU_Change_state() and _Per_CPU_Wait_for_state(). Add prototype for _SMP_Send_message(). Delete RTEMS_BSP_SMP_FIRST_TASK message. The first context switch is now performed in rtems_smp_secondary_cpu_initialize(). Issuing the first context switch in the context of the inter-processor interrupt is not possible on systems with a modern interrupt controller. Such an interrupt controler usually requires a handshake protocol with interrupt acknowledge and end of interrupt signals. A direct context switch in an interrupt handler circumvents the interrupt processing epilogue and may leave the system in an inconsistent state. Release lock in rtems_smp_process_interrupt() even if no message was delivered. This prevents deadlock of the system. Simplify and format _SMP_Send_message(), _SMP_Request_other_cores_to_perform_first_context_switch(), _SMP_Request_other_cores_to_dispatch() and _SMP_Request_other_cores_to_shutdown().
8:54 AM Changeset in rtems [e358088]4.11 by Sebastian Huber <sebastian.huber@…>
smp: New SMP lock API Move the SMP lock implementation to the CPU port. An optimal SMP lock implementation is highly architecture dependent. For example the memory models may be fundamentally different. The new SMP lock API has a flaw. It does not provide the ability to use a local context for acquire and release pairs. Such a context is necessary to implement for example the Mellor-Crummey and Scott (MCS) locks. The SMP lock is currently used in _Thread_Disable_dispatch() and _Thread_Enable_dispatch() and makes them to a giant lock acquire and release. Since these functions do not pass state information via a local context there is currently no use case for such a feature.

3:31 PM Changeset in rtems [e3be691]4.11 by Sebastian Huber <sebastian.huber@…>
score: Remove idle field of Per_CPU_Control This field is unused except for special case simulator clock drivers. In these places use an alternative. Add and use _Thread_Set_global_exit_status() and _Thread_Get_global_exit_status().
3:29 PM Changeset in rtems [17e09f8]4.11 by Sebastian Huber <sebastian.huber@…>
bsps: Use _Objects_Information_table Eliminate copy and paste. Use the _Objects_Information_table since this will take into account that more than one internal thread may exist, e.g. MPCI thread or idle threads of secondary processors.
12:47 PM Changeset in rtems [d65de8a1]4.11 by Ralf Corsépius <ralf.corsepius@…>
Update from automake-1.13.2.
10:43 AM Changeset in rtems [0d671d70]4.11 by Sebastian Huber <sebastian.huber@…>
bsps/arm: Move .fast_text section Move the .fast_text section after the .vector section. The .fast_test section is normally not empty in case some functions should execute from an internal SRAM. This would be also the area for the .vector section. The vector table must be the first content of such an area.

1:48 PM Changeset in rtems [83a4cbb]4.11 by Ralf Kirchner <ralf.kirchner@…>
dosfs: UTF-8 Support: Multibyte conversions Add optional conversion methods for multibyte strings. With these conversions which make use of iconv and utf8proc it becomes possible to use strings from any language (Czech, Chinese, Arabian, Hebrew, Corean, ...) for file names and directory names. NOTE: Iconv support must be activated during the build of the tool chain for these conversion methods (options --enable-newlib-iconv --enable-newlib-iconv-encodings=[ENCODINGS_YOU_WANT]). Alternatively you can provide your own conversion methods.

arm: Fix CPSR and SPSR access The GNU assembler translates for example a msr spsr, rN into msr SPSR_fc, rN This would update only a subset of the register and leads to an incomplete exceptions restore sequence resulting in system corruption. Correct is this: msr SPSR_fsxc, rN

dosfs: UTF-8 Support: UI, backwards compatibility User interface and backwards compatibility for UTF-8 support in the FAT file system. Purpose of UTF-8 support is to permit file names and directory names with characters from all kinds of languages (Czech, Chinese, Arabian, Hebrew, Korean, ...). This commit does not yet support multibyte characters. It only contains the user interface and the backwards compatibility.
