* score: Rework thread priority managementSebastian Huber2016-09-212-4/+4
| | | | | | | | | | | | | | | | | | | | | | | | | Add priority nodes which contribute to the overall thread priority. The actual priority of a thread is now an aggregation of priority nodes. The thread priority aggregation for the home scheduler instance of a thread consists of at least one priority node, which is normally the real priority of the thread. The locking protocols (e.g. priority ceiling and priority inheritance), rate-monotonic period objects and the POSIX sporadic server add, change and remove priority nodes. A thread changes its priority now immediately, e.g. priority changes are not deferred until the thread releases its last resource. Replace the _Thread_Change_priority() function with * _Thread_Priority_perform_actions(), * _Thread_Priority_add(), * _Thread_Priority_remove(), * _Thread_Priority_change(), and * _Thread_Priority_update(). Update #2412. Update #2556.
* score: Introduce _Thread_Get_priority()Sebastian Huber2016-09-083-4/+8
| | | | Avoid direct access to thread internal data fields.
* stackchk: Fix stack checker thread initializationSebastian Huber2016-09-082-30/+4
| | | | | | | Commit 0fd6f25507fbea5f4892b71b58837cdda17856b4 relaxed the thread begin extension execution environment. This broke the stack check which only partially initialized the stack pattern in its create extension. Move the part of the begin extension to the create extension.

* capture: Workaround to avoid misaligned accessSebastian Huber2016-09-061-1/+1
| | | | | Move the 64-bit field to a not 64-bit aligned structure offset to stop the compiler from generating 64-bit load/store operations.

* libmisc/capture: Fix the capture engine on SMP.Chris Johns2016-09-019-666/+880
| | | | | | | | | | | | | | | | | | | | | | | This patches some issues with the capture engine: 1. Check is the engine is open in ctrace commands. 2. Check all record open and appends for overflow. 3. Fix the record open to take the size of user data and not the record header. 4. Use packed structs for data being written to the per cpu buffers. 5. Remove direct struct access to the capture buffers to avoid misaligned accesses. 6. Add support to extract records, no struct access to the capture buffers. 7. Update ctrace to extract records from the capture buffers. 8. Add support to ctrace to always print the task name if it has one. 9. Add support to manage names or the lack of a name. 10. Range of minor fixes. 11. Fix a long standing bug in ctset's handling of args. Closes #2780.
* libmisc/untar: Set the perms to the value in the tar file.Chris Johns2016-08-092-20/+34
| | | | | | | This patch parses the mode field in the tar header and sets the directory or file to the mode value in the header. Closes #2768.
* score: Turn thread lock into thread wait lockSebastian Huber2016-07-271-4/+3
| | | | | | | | | The _Thread_Lock_acquire() function had a potentially infinite run-time due to the lack of fairness at atomic operations level. Update #2412. Update #2556. Update #2765.

* score: Introduce map priority scheduler operationSebastian Huber2016-06-221-2/+4
| | | | | | | | | | | Introduce map/unmap priority scheduler operations to map thread priority values from/to the user domain to/from the scheduler domain. Use the map priority operation to validate the thread priority. The EDF schedulers use this new operation to distinguish between normal priorities and priorities obtain through a job release. Update #2173. Update #2556.
* rtems: Rework RTEMS API to SuperCore prioritySebastian Huber2016-06-222-6/+6
| | | | | Use same structure as POSIX API for thread priority conversion to/from SuperCore.
* Rename rtems_test_print() into rtems_test_printf()Sebastian Huber2016-06-222-2/+2
|
* Move printer initialization to separate headerSebastian Huber2016-06-2212-1/+12
| | | | | | The RTEMS print user need to know nothing about a particular printer implementation. In particular get rid of the <stdio.h> include which would be visible via <rtems.h>.
* Make rtems/print.h independent of rtems/bspIo.hSebastian Huber2016-06-222-0/+2

* Rename and move RTEMS_PRINTF_ATTRIBUTE()Sebastian Huber2016-06-221-1/+1
| | | | | Rename RTEMS_PRINTF_ATTRIBUTE() into RTEMS_PRINTFLIKE() (similar to <sys/cdefs.h> __printflike()) and move it to <rtems/score/basedefs.h>.

* libmisc/untar: Support directory create and overwrites. Share the common code.Chris Johns2016-06-032-127/+343
| | | | | | | | | | | | | | | | | | | Support creating directories for files with a path depth greater than 1. Some tar files can have files with a path depth greater than 1 and no directory entry in the tar file to create a directory. Support overwriting existing files and directories failing in a similar way to tar on common hosts. If a file is replaced with a file delete the file and create a new file. If a directory replaces a file remove the file and create the directory. If a file replaces a directory remove the directory, and if the directory is not empty and cannot be removed report an error. If a directory alreday exists do nothing leaving the contents untouched. The untar code now shares the common header parsing and initial processing with the actual writes still separate. No changes to the IMFS have been made. Updates #2415. Closes #2207.

* score: Rework CORE inherit priority mutexSebastian Huber2016-05-301-22/+72
| | | | | Provide dedicated seize and surrender methods for inherit priority mutexes. This eliminates CORE_mutex_Attributes.
* score: Add CORE mutex variantsSebastian Huber2016-05-301-2/+3
| | | | | | | | Add CORE_recursive_mutex_Control and CORE_ceiling_mutex_Control to avoid the run-time evaluation of attributes to figure out how a particular mutex methods should behave. Start with the no protocol variants. This eliminates the CORE_MUTEX_DISCIPLINES_FIFO and CORE_MUTEX_DISCIPLINES_PRIORITY disciplines.
* libmisc: Fix printk format warnings.Chris Johns2016-05-252-3/+3

* cpukit, testsuite: Add rtems_printf and rtems_printer support.Chris Johns2016-05-2516-227/+172
| | | | | | | | | | | | | | | | | | | This change adds rtems_printf and related functions and wraps the RTEMS print plugin support into a user API. All references to the plugin are removed and replaced with the rtems_printer interface. Printk and related functions are made to return a valid number of characters formatted and output. The function attribute to check printf functions has been added to rtems_printf and printk. No changes to remove warrnings are part of this patch set. The testsuite has been moved over to the rtems_printer. The testsuite has a mix of rtems_printer access and direct print control via the tmacros.h header file. The support for begink/endk has been removed as it served no purpose and only confused the code base. The testsuite has not been refactored to use rtems_printf. This is future work.
* score: Rework _Thread_Restart_other()Sebastian Huber2016-05-201-1/+1

Add _Thread_Wait_get_id() to obtain the object identifier for debug and system information tools. Ensure the object layout via static asserts. Add test cases to sptests/spthreadq01.
