* cpukit/libmisc/dumpbuf/dumpbuf.c: Fix compilation warningsMartin Galvan2015-09-031-1/+1
| | | | | | | | | | Compiling dumpbuf.c causes the following warning to be issued: warning: pointer targets in passing argument 1 of 'snprintf' differ in signedness [-Wpointer-sign] This happens because line_buffer is declared as unsigned. Closes #2411.
* cpukit/libnetworking/rtems/rtems_dhcp.c: Fix compilation errorMartin Galvan2015-09-031-1/+1
| | | | | | | | Apparently 'free' is defined as a macro which takes two arguments and calls rtems_bsdnet_free. When fixing #2405 I added a missing 'free' but didn't notice it was non-standard. Closes #2410.
* cpukit/libmisc/dumpbuf/dumpbuf.c: Fix undefined behavior for sprintf()Martin Galvan2015-09-031-46/+75
| | | | | | | I also used the 'n' versions of the string functions, #define'd magic numbers and added a few comments. Updates #2405.
* cpukit/libnetworking/rtems/rtems_dhcp.c: Fix leak on realloc failure for ↵Martin Galvan2015-09-031-5/+13
| | | | | | dhcp_hostname. Closes #2405.

* rbtree: Add _RBTree_Replace_node()Sebastian Huber2015-09-033-0/+75
|
* rbtree: Replace implementationSebastian Huber2015-09-036-578/+202
| | | | | Use the BSD <sys/tree.h> implementation since it is faster, more flexible and uses less storage. See https://github.com/sebhub/rb-bench.
* score: Optimize thread queue first operationSebastian Huber2015-09-021-5/+10
| | | | | In case the thread queue heads exist, then the queue is not empty. See _Thread_queue_First_locked().

|
* score: Fix return status of mutex try acquireSebastian Huber2015-09-011-9/+9

|
* rbtree: Delete rtems_rbtree_find_control()Sebastian Huber2015-09-012-35/+0
| | | | | This function is hard to support in alternative implementations. It has no internal use case.

|
* rbtree: Delete _RBTree_Initialize()Sebastian Huber2015-08-316-79/+58
| | | | This function has no internal use case.

| | | | Fixes link failure when linking Ada programs on the raspberry pi
* score: Add self-contained condition implementationSebastian Huber2015-07-304-0/+314

|
* score: Add self-contained semaphore implementationSebastian Huber2015-07-304-0/+146
|
* score: Add self-contained mutex implementationSebastian Huber2015-07-304-0/+447
| | | | | | | This mutex implementation uses a thread priority queue with a simple priority inheritance mechanism (similar to the object based mutexes). The storage space must be supplied by the user (16 bytes on 32-bit targets).
* score: Add thread queue for self-contained objectsSebastian Huber2015-07-303-0/+55
|
* score: Use a plain ticket lock for thread locksSebastian Huber2015-07-309-45/+149
| | | | | | This enables external libraries to use thread locks since they are independent of the actual RTEMS build configuration, e.g. profiling enabled or disabled.
* score: Add potpourri lock statisticsSebastian Huber2015-07-303-0/+14
| | | | | | | These SMP lock statistics are used for all lock objects that lack a storage space for the statistics. Examples are lock objects used in external libraries which are independent of the actual RTEMS build configuration.
* score: Provide struct _Thread_queue_HeadsSebastian Huber2015-07-301-1/+7
| | | | | Use a leading underscore in the structure name to allow forward declarations in standard header files provided by Newlib and GCC.
* score: Rename struct Thread_ControlSebastian Huber2015-07-303-7/+10
| | | | | Add a leading underscore to the structure name to allow forward declarations in standard header files provided by Newlib and GCC.
* tftpDriver: close() false errorMichael Davidsaver2015-07-291-1/+3
| | | | closes #2376.
* score: Rename _POSIX_Absolute_timeout_to_ticks()Sebastian Huber2015-07-2898-238/+101
| | | | | | Rename _POSIX_Absolute_timeout_to_ticks() to _TOD_Absolute_timeout_to_ticks() and move it to the score directory. Delete empty <rtems/posix/time.h>.

|
* monitor: Print addresses like identifiersSebastian Huber2015-07-242-3/+3
| | | | This avoids the "0x0xabc" output and is more compact.

|
* score: Move wait flag update to tq extractSebastian Huber2015-07-233-15/+34
| | | | | | This makes it possible to use _Thread_queue_Extract_locked() for barrier operations which extract all threads on the queue in one critical section.
* score: Introduce Thread_queue_HeadsSebastian Huber2015-07-2322-124/+313
| | | | | | | | | | | | | Move the storage for the thread queue heads to the threads. Each thread provides a set of thread queue heads allocated from a dedicated memory pool. In case a thread blocks on a queue, then it lends its heads to the queue. In case the thread unblocks, then it takes a free set of threads from the queue. Since a thread can block on at most one queue this works. This mechanism is used in FreeBSD. The motivation for this change is to reduce the memory demands of the synchronization objects. On a 32-bit uni-processor configuration the Thread_queue_Control size is now 8 bytes, compared to 64 bytes in RTEMS 4.10 (other changes reduced the size as well).
