2015-12-24api: Remove deprecated NotepadsAun-Ali Zaidi1-69/+0
Notepads where a feature of RTEMS' tasks that simply functioned in the same way as POSIX keys or threaded local storage (TLS). They were introduced well before per task variables, which are also deprecated, and were barely used in favor of their POSIX alternatives. In addition to their scarce usage, Notepads took up unnecessary memory. For each task: - 16 32-bit integers were allocated. - A total of 64 bytes per task per thread. This is especially critical in low memory and safety-critical applications. They are also defined as uint32_t, and therefore are not guaranteed to hold a pointer. Lastly, they are not portable solutions for SMP and uniprocessor systems, like POSIX keys and TLS. updates #2493.

2015-03-10cpukit: deprecate notepadsGedare Bloom1-5/+41
Deprecate Classic API Notepads. Mark task_set/get_note() with the deprecated attribute, and also mark the notepads field. Replace disable with enable option for notepads in confdefs.h, and make notepads disabled by default. The previous option CONFIGURE_DISABLE_CLASSIC_API_NOTEPADS is now unused and will emit a compile-time warning. A new option CONFIGURE_ENABLE_CLASSIC_API_NOTEPADS is available to turn on notepads, but it also will emit a compile-time warning to indicate that notepads are deprecated. Closes #2265

2014-05-28score: Multiprocessor Resource Sharing ProtocolSebastian Huber1-0/+32
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.

2014-04-15score: Add clustered/partitioned schedulingSebastian Huber1-13/+194
Clustered/partitioned scheduling helps to control the worst-case latencies in the system. The goal is to reduce the amount of shared state in the system and thus prevention of lock contention. Modern multi-processor systems tend to have several layers of data and instruction caches. With clustered/partitioned scheduling it is possible to honour the cache topology of a system and thus avoid expensive cache synchronization traffic. We have clustered scheduling in case the set of processors of a system is partitioned into non-empty pairwise-disjoint subsets. These subsets are called clusters. Clusters with a cardinality of one are partitions. Each cluster is owned by exactly one scheduler instance.

2014-04-15score: Static scheduler configurationSebastian Huber1-7/+9
Do not allocate the scheduler control structures from the workspace. This is a preparation step for configuration of clustered/partitioned schedulers on SMP.
2014-04-10score: Statically initialize IO managerSebastian Huber1-33/+35
This simplifies the RTEMS initialization and helps to avoid a memory overhead. The workspace demands of the IO manager were not included in the <rtems/confdefs.h> workspace size estimate. This is also fixed as a side-effect. Update documentation and move "Specifying Application Defined Device Driver Table" to the section end. This sub-section is not that important for the user. Mentioning this at the beginning may lead to confusion.

This patch includes a heavy rewrite of the chapter to have a more structured approach to this chapter. It also changes the sectioning to have the Data Structures be a section to themselves as a peer in the outline with each logical area of macros in confdefs.h.

2012-03-27confdefs: Add declaration for unlimited objects.Gedare Bloom1-19/+74
Adds to confdefs a way to specify rtems_resource_unlimited for classic and posix objects using a new macro CONFIGURE_OBJECTS_UNLIMITED. Use CONFIGURE_OBJECTS_ALLOCATION_SIZE to declare the allocation size for extending the set of objects at runtime. Updates the unlimited sample to demonstrate how to use the new macros. Also adds new documentation in the C User's Manual regarding configuring with unlimited objects.
