* src/extensionident.c: Added ID to name lookup service and changed
name of id/name translation status code. This propagated to multiple
functions. The user API service added was rtems_object_id_to_name()
* Jump table for single entry point removed.
* include/rtems/directives.h, src/entrytable.c: Removed.
* include/Makefile.am, src/Makefile.am, src/exinit.c: Modified to
reflect above.
* Mega patch merge to change the format of the object IDs to
loosen the dependency between the SCORE and the various APIs.
There was considerable work to simplify the object name management
and it appears that the name_table field is no longer needed.
This patch also includes the addition of the internal mutex
which is currently only used to protect some types of allocation
and deallocation. This significantly can reduce context
switch latency under certain circumstances. In particular,
some heap/region operations were O(n) and had dispatching
disabled. This should help enormously. With this merge,
the patch is not as clean as it should be. In particular,
the documentation has not been modified to reflect the new object
ID layout, the IDs in the test screens are not updated, and
_Objects_Get_information needs to be a real routine not inlined.
As part of this patch a lot of MP code for thread/proxy blocking
was made conditional and cleaned up.
* include/confdefs.h, src/exinit.c, src/extension.c, src/itronapi.c,
src/posixapi.c, src/rtemsapi.c: Modified as part of above.
* src/exinit.c: Slightly rework initialization so there
is a valid thread as _Thread_Executing when the pre_tasking
hook is called. This allows one directives and malloc
to potentially use mutex protection.
* PR132 requested some tinkering ot lower memory.
* include/confdefs.h: Lowered footprint of device driver table
and statically configure user extensions. Now if no static
extensions are configured, then the table is not instantiated.
* optman/, optman/.cvsignore, optman/Makefile.am, optman/no-ext.c,
optman/no-io.c: Removed entire contents of optman/ directory since
it has been moved.
* configure.ac: Use AS_IF instead of if/then/else.
Add AC_DEFINE_UNQUOTED(RTEMS_UNIX) for RTEMS_CPU==unix.
Add AC_DEFINE_UNQUOTED(RTEMS_UNIXLIB) for RTEMS_CPU==unix.
Add include/Makefile to CONFIG_FILES.
Add AC_ENABLE_MULITLIB.
Remove wrapup/rtems, wrapup/itron, wrapup/posix.
Remove */optman/Makefile from CONFIG_FILES.
* Makefile.am: Add include to SUBDIRS.
* rtems/Makefile.am: Remove optman from SUBDIRS.
* sapi/Makefile.am: Remove optman from SUBDIRS.
* include/Makefile.am: New file.
* include/rtems/bspIo.h: Relocated from lib/include.
* include/rtems/libio_.h: Relocated from lib/include.
* include/confdefs.h, include/rtems/config.h, include/rtems/io.h,
optman/no-io.c, src/exinit.c, src/io.c: Added a device driver
register/unregister interface to allow device drivers to be
installed and removed at runtime. This means you do not need devices
present in the device table when you build.
* include/rtems/Makefile.am: Use 'PREINSTALL_FILES ='.
* include/Makefile.am: Use 'PREINSTALL_FILES ='.
* inline/rtems/Makefile.am: Use 'PREINSTALL_FILES ='.
* macros/rtems/Makefile.am: Use 'PREINSTALL_FILES ='.
* POSIX include files merged into newlib. This resulted in
some definitions moving to other files and thus some secondary
effects in RTEMS source code.
* include/confdefs.h: Replaced include of <sys/siginfo.h> with
<signal.h> since that file no longer exists.
* include/confdefs.h: Modified code that accounts for initialization
task/threads with greater than minimum stack sizes so it would
compile even if optional APIs are disabled.
that contains:
* Removes remaining (now illegal) references to $(SRC) from a couple of
Makefile.ams
* Removes duplicate AC_CONFIG_SUBDIRS macro from c/configure.in
* Moves ENABLE_LIBCDIR into RTEMS_PROG_C[C|XX]_FOR_TARGET (hides LIBCDIR
from most configure scripts, i.e. LIBCDIR becomes less visible)
* Adds RTEMS_PROG_C[C|XX]_FOR_TARGET and RTEMS_CANONICALIZE_TOOLS to
libbsp/*/configure.ins (A minor bug in previous implementations, which
only has an impact when switching to GNU/Cygnus canonicalization)
* Cleans up several bogus comments.
* Removes MKLIB
* Switches the version number to 4.5.0 (for testing version number
handling)
.. a major configuration cleanup
... major enhancement of automake support.
... and it contains a *major* breakthough:
Automake support for libchip and libmisc *LEAF* directories.
To implement this I have used several nasty tricks
* The basical trick is to wrap an old Makefile.in's contents into a
Makefile.am and still continue to use (i.e include) the old
*.cfg files.
* Replaced each INSTALL_IF_CHANGE and INSTALL_VARIANT with make
dependencies
* Add a gnu-make ifdef AUTOMAKE to main.cfg to avoid conflicts between
automake and RTEMS make rules
* Replaced each install:: and preinstall:: rule with make dependencies
* Replaced SUB_DIRS with SUBDIRS in all Makefile.ins (Automake
convention)
* Removed each manually added autoconf substitution which automake
performs automatically.
This is not yet full automake support, because using the temporary
installation directory, preinstallation in general and building variants
are in contradiction to automake's basic working principles ...
... the new Makefile.ams work still somewhat clumsy
... nevertheless they work (quite well).
WARNING:
At first glance this patch is small, but
* it affects the whole configuration system.
* it opens the road to introducing automake to all Makefile.ins
currently not being under automake control.
JOEL> Does this remove or add any files?
Both, all Makefile.ins below libchip and libmisc get replaced with
Makefile.ams.
unnecessarily uses any variables defined by the BSP. On this
sweep, use of BSP_Configuration and Cpu_table was eliminated.
A significant part of this modification was the addition of
macros to access fields in the RTEMS configuration structures.
This is necessary to strengthen the division between the BSP independent
parts of RTEMS and the BSPs themselves. This started after
comments and analysis by Ralf Corsepius <corsepiu@faw.uni-ulm.de>.
particular, using bsp.h, or getting information from the BSP which
should properly be obtained from RTEMS is forbidden. This is
necessary to strengthen the division between the BSP independent
parts of RTEMS and the BSPs themselves. This started after
comments and analysis by Ralf Corsepius <corsepiu@faw.uni-ulm.de>.
The changes primarily eliminated the need to include bsp.h and
peeking at BSP_Configuration. The use of Cpu_table in each
BSP needs to be eliminated.
