* sapi/include/confdefs.h: When you disabled newlib reentrancy, it
still reserved memory for the reentrancy structure. This is about 1K
per task. On psim, we now reserve only 1936 bytes and only 240 remain
after all allocations. Further analysis will be required to narrow
that down. In addition, the new constant CONFIGURE_CONFDEFS_DEBUG can
be defined and the structure named Configuration_Memory_Debug will be
instantiated. This structure contains many of the component values
that go into the memory reservation computation. This is helpful when
tracking down problems.
* sapi/include/confdefs.h: The math in the _Configure_Object_RAM macro
was always adding heap overhead even when the number of objects
configured was zero and we would not do an allocation. This resulted
in an over estimation of the amount of Workspace required (~2K on
minimum.exe on PowerPC).
* cpukit/sapi/include/confdefs.h: Add missing quote to string to
remove warning.
* cpukit/score/cpu/m68k/rtems/score/m68k.h: Add the default
priority level for large memory Coldfires.
* posix/include/rtems/posix/pthread.h, posix/src/pthread.c,
posix/src/pthreadcreate.c, rtems/include/rtems.h, rtems/src/attr.c,
sapi/include/confdefs.h, sapi/include/rtems/config.h,
score/inline/rtems/score/stack.inl, score/src/isr.c,
score/src/mpci.c, score/src/threadcreateidle.c,
score/src/threadinitialize.c, score/src/threadstackallocate.c: Add
ability for application to configure minimum stack size. Add
RTEMS_CONFIGURED_MINIMUM_STACK_SIZE constant so user can clearly
indicate they want the configured as opposed to the recommended
minimum stack size.
* sapi/include/confdefs.h: Rework to be more accurate on allocation. In
particular, there was a report from that Matthew Riek that memory was
being reserved twice for the IDLE task. This was covering up other
places that under allocated memory. Before I was done, I had reworked
the file to be easier to read, maintain and be more accurate.
reduce size of data area.
IMFS: Fixed creation of symbolic links to avoid a compiler warning.
DOSFS: Use LibBlock instead of read() to read the boot record.
* sapi/include/rtems/init.h, sapi/src/exinit.c: Refactored and renamed
initialization routines to rtems_initialize_data_structures,
rtems_initialize_before_drivers, rtems_initialize_device_drivers, and
rtems_initialize_start_multitasking. This opened the sequence up so
that bootcard() could provide a more robust and flexible framework
which is easier to explain and understand. This also lays the
groundwork for sharing the division of available memory between the
RTEMS workspace and heap and the C library initialization across all
BSPs.
* libmisc/dummy/dummy.c, sapi/include/confdefs.h: Add checks for
application configuration errors. If any POSIX objects or a POSIX
init thread is configured without POSIX being configure, then error
out. Similarly for ITRON. Add
CONFIGURE_APPLICATION_DOES_NOT_NEED_CLOCK_DRIVER configuration
parameter so the application has to explicitly configure the Clock
driver in or out if the Timer driver is not configured. Also verify
RTEMS was built for multiprocessing, if the user tries to configure a
multiprocessing application.
* sapi/include/confdefs.h: Do not reserve 2 * minimum stack size
for the ITRON initialization tasks ALL the time.
Do not reserve memory for the object name table since it does not
exist any longer.
* sapi/include/rtems/sptables.h: Fix typo.
* sapi/include/rtems/config.h, sapi/include/rtems/sptables.h: Add
missing field to default multiprocessing configuration table. Also
document fields in Doxygen format.
* sapi/include/confdefs.h, score/src/mpci.c, score/src/objectmp.c,
score/src/objectnametoid.c, score/src/objectnametoidstring.c:
Multiprocessing compiles again and survives initialization. The
recent object name and confdefs.h changes had broken it.
* sapi/include/rtems/fatal.h, score/include/rtems/score/coremutex.h,
score/include/rtems/score/interr.h,
score/inline/rtems/score/thread.inl, score/src/coremutexseize.c:
Modifications to aid in full path testing.

score/src/objectextendinformation.c,
score/src/objectgetnameasstring.c, score/src/objectmp.c,
score/src/objectnametoid.c: Convert the Objects_Name type from a
simple type to a union of an unsigned 32 bit integer and a pointer.
This should help eliminate weird casts between u32 and pointers in
various places. The APIs now have to explicitly call _u32 or _string
versions of helper routines. This should also simplify things and
eliminate the need for ugly casts in some cases.
* score/src/objectclearname.c, score/src/objectcomparenameraw.c,
score/src/objectcomparenamestring.c, score/src/objectcopynameraw.c,
score/src/objectcopynamestring.c: Removed.
* libcsupport/Makefile.am: Add malloc_sbrk_helpers.c.
* libcsupport/include/rtems/malloc.h,
libcsupport/src/malloc.c, libcsupport/src/malloc_initialize.c,
libcsupport/src/malloc_p.h,
libcsupport/src/malloc_statistics_helpers.c: Make sbrk()
support pluggable and optional. This eliminates the need for
heap extend and sbrk in the minimum footprint which is ~2.5K on
the SPARC.
* sapi/include/confdefs.h: Add the following configuration points:
+ CONFIGURE_MALLOC_STATISTICS
+ CONFIGURE_MALLOC_BSP_SUPPORTS_SBRK
* libcsupport/src/malloc_sbrk_helpers.c: New file.
* score/src/threadhandler.c, sapi/src/exshutdown.c:
cannot call _fini via atexit() from rtems_shutdown_executive()
because at the point where rtems_shutdown_executive is called
the C-library is already dead.
Instead, register an atexit(_fini) after calling _init().
* Makefile.am: Added libmisc/shell/shellconfig.h to the installed
header list.
* libmisc/shell/shell_cmdset.c: Let the Initial command add occur
in any order rather than before any commands have been added. Also
made the command's strings be copies rather than references.
* sapi/src/ioregisterdriver.c: Return the I/O initialise calls result.
* sapi/include/confdefs.h, sapi/include/rtems/config.h,
sapi/include/rtems/init.h, sapi/src/exinit.c,
score/include/rtems/system.h, score/src/isr.c: Move
interrupt_stack_size field from CPU Table to Configuration Table.
Eliminate CPU Table from all ports. Delete references to CPU Table in
all forms.
* libcsupport/src/malloc.c, libmisc/monitor/mon-command.c,
posix/preinstall.am, posix/include/rtems/posix/cond.h,
posix/include/rtems/posix/mqueue.h,

score/src/thread.c, score/src/threadcreateidle.c,
score/src/threadstackallocate.c, score/src/threadstackfree.c,
score/src/wkspace.c: Moved most of the remaining CPU Table fields to
the Configuration Table. This included pretasking_hook,
predriver_hook, postdriver_hook, idle_task, do_zero_of_workspace,
extra_mpci_receive_server_stack, stack_allocate_hook, and
stack_free_hook. As a side-effect of this effort some multiprocessing
code was made conditional and some style clean up occurred.
* sapi/src/exinit.c, score/include/rtems/score/object.h,
score/include/rtems/score/thread.h, score/src/object.c,
score/src/thread.c: Conditionally compile out more code that is
specific to multiprocessor configurations.
* sapi/src/exinit.c, score/Makefile.am,
score/include/rtems/score/apimutex.h: API Mutex calls should never
have been inlined. Inlining them lead to many inlined copies of core
mutex lock. This lead to over 2K savings in the SPARC/ERC32
minimum.exe.
* score/src/apimutex.c, score/src/apimutexallocate.c,
score/src/apimutexlock.c, score/src/apimutexunlock.c: New files.
* sapi/Makefile.am, sapi/include/rtems/io.h, sapi/src/io.c: Split into
one function per file execpt io.c which contains required
initialization methods.
* sapi/src/ioclose.c, sapi/src/iocontrol.c, sapi/src/iodata.c,
sapi/src/ioinitialize.c, sapi/src/ioopen.c, sapi/src/ioread.c,
sapi/src/ioregisterdriver.c, sapi/src/iounregisterdriver.c,
sapi/src/iowrite.c: New files.
* sapi/include/confdefs.h, sapi/src/io.c: Readded code to copy driver
table into Workspace but now it is only done if the application needs
extra slots for dynamic driver registration. Cleaned up
rtems_io_register_driver and rtems_io_unregister_driver code and
added numerous error cases to register.
* libmisc/Makefile.am, libmisc/monitor/mon-object.c,
libmisc/monitor/monitor.h, sapi/include/confdefs.h,
sapi/include/rtems/config.h, sapi/include/rtems/io.h,
sapi/src/exinit.c, sapi/src/io.c: Eliminate maximum_drivers
configuration parameter since it was used to configure a no longer
used feature. Device names are now part of the filesystem not in a
table. This also eliminated the variables _IO_Number_of_devices and
_IO_Driver_name_table from RTEMS as well as the memory allocation
used to populate _IO_Driver_name_table.
* libmisc/monitor/mon-dname.c: Removed.
* sapi/include/confdefs.h: Add CONFIGURE_MESSAGE_BUFFER_MEMORY so there
is less dependence on CONFIGURE_MEMORY_OVERHEAD. Do not arbitrarily
add 1 to CONFIGURE_MEMORY_OVERHEAD so we do not waste a kilobyte for
unused Workspace. Round the workspace required size to an 8 byte
boundary instead of a 0x400 byte one. We may end up needing to add 8
bytes again to account for the alignment rounding.
