2018-01-25Remove make preinstallChris Johns1-0/+0
A speciality of the RTEMS build system was the make preinstall step. It copied header files from arbitrary locations into the build tree. The header files were included via the -Bsome/build/tree/path GCC command line option. This has at least seven problems: * The make preinstall step itself needs time and disk space. * Errors in header files show up in the build tree copy. This makes it hard for editors to open the right file to fix the error. * There is no clear relationship between source and build tree header files. This makes an audit of the build process difficult. * The visibility of all header files in the build tree makes it difficult to enforce API barriers. For example it is discouraged to use BSP-specifics in the cpukit. * An introduction of a new build system is difficult. * Include paths specified by the -B option are system headers. This may suppress warnings. * The parallel build had sporadic failures on some hosts. This patch removes the make preinstall step. All installed header files are moved to dedicated include directories in the source tree. Let @RTEMS_CPU@ be the target architecture, e.g. arm, powerpc, sparc, etc. Let @RTEMS_BSP_FAMILIY@ be a BSP family base directory, e.g. erc32, imx, qoriq, etc. The new cpukit include directories are: * cpukit/include * cpukit/score/cpu/@RTEMS_CPU@/include * cpukit/libnetworking The new BSP include directories are: * bsps/include * bsps/@RTEMS_CPU@/include * bsps/@RTEMS_CPU@/@RTEMS_BSP_FAMILIY@/include There are build tree include directories for generated files. The include directory order favours the most general header file, e.g. it is not possible to override general header files via the include path order. The "bootstrap -p" option was removed. The new "bootstrap -H" option should be used to regenerate the "headers.am" files. Update #3254.
2017-12-04score: Use self-contained API mutexSebastian Huber1-10/+6
Use a self-contained recursive mutex for API_Mutex_Control. The API mutexes are protected against asynchronous thread cancellation. Add dedicated mutexes for libatomic and TOD. Close #2629. Close #2630.

Update #3117. Update #3182.
2017-10-09score: Change Timestamp_Control to sbintime_tSebastian Huber1-3/+2
The timestamp are based on the uptime. There is no need for a 64-bit seconds part. The signed 32-bit seconds part of the sbintime_t limits the uptime to roughly 68 years. Close #2740.
2017-10-09score: Use struct timespec for TODSebastian Huber1-46/+8
Use the timestamps only for uptime based values. Use struct timespec for the absolute time values (TOD). Update #2740.

2016-05-02score: Streamline set time of day functionsSebastian Huber1-16/+9
Rename _TOD_Set() into _TOD_Set_with_timespec(). Rename _TOD_Set_with_timestamp() into _TOD_Set(). This is now in line with _TOD_Get() and _TOD_Get_as_timespec(). The timestamp is the canonical format.

2014-07-23Add _TOD_Adjust to SCORE TOD Handler.Joel Sherrill1-0/+12
This lays the proper structure for doing future work on time adjustment algorithms. Any TOD adjustments should be requested at the API level and performed at the SCORE level. Additionally updated a test.
2014-03-21Change all references of rtems.com to rtems.org.Chris Johns1-1/+1
2014-03-11score: Add local context to SMP lock APISebastian Huber1-4/+4
Add a local context structure to the SMP lock API for acquire and release pairs. This context can be used to store the ISR level and profiling information. It may be later used to enable more sophisticated lock algorithms, e.g. MCS locks. There is only one lock that cannot be used with a local context. This is the per-CPU lock since here we would have to transfer the local context through a context switch which is very complicated.
2013-08-01score: Use an ISR lock for TODSebastian Huber1-10/+25
Two issues are addressed. 1. On single processor configurations the set/get of the now/uptime timestamps is now consistently protected by ISR disable/enable sequences. Previously nested interrupts could observe partially written values since 64-bit writes are not atomic on 32-bit architectures in general. This could lead to non-monotonic uptime timestamps. 2. The TOD now/uptime maintanence is now independent of the giant lock. This is the first step to remove the giant lock in _Thread_Dispatch().
2013-08-01score: Move nanoseconds since last tick supportSebastian Huber1-1/+15
Move the nanoseconds since last tick support from the Watchdog to the TOD handler. Now the TOD managment is encapsulated in the TOD_Control structure.

2012-10-02score/tod.h: Fix formattingJoel Sherrill1-2/+2
2012-06-14score: Fix performance issue for 64-bit timestampsSebastian Huber1-0/+9
The 64-bit timestamps were introduced to simplify the timestamp calculations. This works well since nearly all operations are additions. The previous _TOD_Tickle_ticks() implementation had a serious performance regression in case of 64-bit timestamps due to the usage of two 64-bit divisions which are quite expensive on some architectures. A new field seconds_trigger in TOD_Control is introduced to trigger the _Watchdog_Tickle_seconds() in _TOD_Tickle_ticks(). This avoids the 64-bit divisions completely and only 32-bit additions are used.
2012-06-14score: New structure TOD_ControlSebastian Huber1-21/+24
Group the global TOD variables (_TOD_Now, _TOD_Uptime, and _TOD_Is_set) in a structure to reduce address loads in _TOD_Tickle_ticks().
