* bsps: Fix TLS support in linker command filesSebastian Huber2014-04-221-1/+3
| | | | | The TLS section symbols had wrong values in case of an empty TLS data section and a nonempty TLS BSS section.

* score: Add clustered/partitioned schedulingSebastian Huber2014-04-151-13/+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.
* score: Add scheduler nameSebastian Huber2014-04-151-0/+37

* score: Static scheduler configurationSebastian Huber2014-04-151-7/+9
| | | | | | Do not allocate the scheduler control structures from the workspace. This is a preparation step for configuration of clustered/partitioned schedulers on SMP.
* score: Statically initialize IO managerSebastian Huber2014-04-101-33/+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.

* documentation: Move CONFIGURE_MAXIMUM_DEVICESSebastian Huber2014-04-101-33/+33
| | | | | | Move CONFIGURE_MAXIMUM_DEVICES documentation to "File System Configuration Parameters". This define has nothing to do with the device driver table.
* Disable per task variables when SMP is enabledJoel Sherrill2014-04-041-2/+17
| | | | | | Per task variables are inherently unsafe in SMP systems. This patch disables them from the build and adds warnings in the appropriate documentation and configuration sections.

* cpukit/shell: Replace task variables with posix keys.Christian Mauderer2014-03-201-0/+3
| | | | | | | | | | | | Use posix keys for current shell environment instead of task variables. With this patch the shell needs one posix-key and one posix-key-value-pair configured. Update documentation for the shell. Adapt samples/fileio: - Add necessary objects. - Add login function and custom device name for better testing of the shell.

* score: Add CPU counter supportSebastian Huber2014-02-141-0/+21
| | | | | | | | | Add a CPU counter interface to allow access to a free-running counter. It is useful to measure short time intervals. This can be used for example to enable profiling of critical low-level functions. Add two busy wait functions rtems_counter_delay_ticks() and rtems_counter_delay_nanoseconds() implemented via the CPU counter.

| | | | | | | | Rename rtems_internal_error_description() to rtems_internal_error_text(). Rename rtems_fatal_source_description() to rtems_fatal_source_text(). Rename rtems_status_code_description() to rtems_status_text(). Remove previous implementation of rtems_status_text().

* cpukit/shell: Control help break with SHELL_LINES env variable.Chris Johns2013-12-161-16/+98
| | | | | | | | Control the help command break with the SHELL_LINES evironment variable where the numeric value is the number of lines to break on. If the value is 0 the output is not broken. The default is 16 lines. Add shell documentation for the help command.
