* doc/started: simplify and fixGedare Bloom2015-03-118-1226/+47
| | | | | | | | | | | | * fix and remove some macros in rtems.texi.in. * refer to devel mailing list. * remove reference to Debian packaging in requirements section. * remove section on prebuilt tools. * replace toolset build instructions with link to RSB docs. * Add a note in building RTEMS section about using RSB. * Fix URLs Closes #2291.

* cpukit: deprecate notepadsGedare Bloom2015-03-103-6/+48
| | | | | | | | | | | | | | | 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

* posix: fix error return code for pthread_mutex_trylockGedare Bloom2015-02-251-2/+2
| | | | | | | | | pthread_mutex_trylock() should return EBUSY if the mutex is already locked. The translations of CORE_MUTEX_STATUS_NESTING_NOT_ALLOWED is EDEADLK which is correct for pthread_mutex_lock(). This fixes the translation for trylock. Closes #2170.

* SPARC: optimize IRQ enable & disableDaniel Hellstrom2014-12-041-4/+27
| | | | | | | | | | | | | | | | * Coding style cleanups. * Use OS reserved trap 0x89 for IRQ Disable * Use OS reserved trap 0x8A for IRQ Enable * Add to SPARC CPU supplement documentation This will result in faster Disable/Enable code since the system trap handler does not need to decode which function the user wants. Besides the IRQ disable/enabled can now be inline which avoids the caller to take into account that o0-o7+g1-g4 registers are destroyed by trap handler. It was also possible to reduce the interrupt trap handler by five instructions due to this.

| | | | | | | Move interrupt lock to device context and expose only this structure to the read, write and set attributes device handler. This makes these device handler independent of the general Termios infrastructure suitable for direct use in printk() support.

* Use correct prototype of benchmark_timer_read()Joel Sherrill2014-09-161-1/+1
| | | | | | | | | | | | | | This change starts with removing the effectively empty file timerdrv.h. The prototypes for benchmark_timer_XXX() were in btimer.h which was not universally used. Thus every use of timerdrv.h had to be changed to btimer.h. Then the prototypes for benchmark_timer_read() had to be adjusted to return benchmark_timer_t rather than int or uint32_t. I took this opportunity to also correct the file headers to separate the copyright from the file description comments which is needed to ensure the copyright isn't propagated into Doxygen output.

* shell: Add a ping command.Chris Johns2014-09-161-21/+290
| | | | | | | | | The ping code is taken from a recent FreeBSD release. Some options have been tested, other not tested or do not work. This could be due to the age of our TCP/IP stack. This version of ping will not work if more than 64 file descriptors are open at once because the select FD size is 64 as set in newlib.

* score: Implement scheduler helping protocolSebastian Huber2014-07-091-0/+78
| | | | | | | | | | | | | | | | | | | | | | | | | 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.
* score: Use Resource Handler for MrsP semaphoresSebastian Huber2014-06-031-1/+10

* score: Multiprocessor Resource Sharing ProtocolSebastian Huber2014-05-283-5/+242
| | | | | | | | | | | | | | | | | | | | | | 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.
