Update #3706.
|
|
This makes the @file documentation independent of the actual file name.
Update #3707.
|
|
The sbintime_t is a non-POSIX type and not visible if strict standard
options are selected.
Move implementation details from <rtems/score/timestamp.h> to
<rtems/score/timestampimpl.h>.
Update #3598.

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.

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.

Replace timestamp implementation with FreeBSD bintime and timecounters.
New test sptests/sptimecounter02.

Add Timestamp support in the score to return a timestamp in nanoseconds.
Add a test.
Update the RTEMS API documentation.
|
|
The output of the modules.html is much improved. Most
filesystem and POSIX API related groups are properly nested.
Some formatting issues were addressed as were multiple
inconsistencies.

This patch is a task from GCI 2012 which improves the Doxygen
comments in the RTEMS source.

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.

Script does what is expected and tries to do it as
smartly as possible.
+ remove occurrences of two blank comment lines
next to each other after Id string line removed.
+ remove entire comment blocks which only exited to
contain CVS Ids
+ If the processing left a blank line at the top of
a file, it was removed.
