* 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.
* minimum/init.c: Exerise new ability for application to configure
minimum stack size. This test still runs the same with a 7.5K stack
on the powerpc but reserves 15K less Workspace on the PowerPC.
* user/bsp.t, user/conf.t, user/task.t: 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.
* 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.
* cpu_asm.S: Add Coldfire FPU support.
* rtems/score/m68k.h: Change the Coldfire CPU defines to be based
on the instruction set. Add Tiny RTEMS support to the small memory
model RTEMS processors.
* rtems/score/cpu.h: Handle the new Tiny RTEMS support.
* custom/av5282.cfg, custom/csb360.cfg, custom/gen68302.cfg,
custom/gen68340.cfg, custom/gen68360.cfg, custom/mcf5206elite.cfg,
custom/mcf5235.cfg, custom/mrm332.cfg, custom/mvme136.cfg,
custom/mvme147.cfg, custom/mvme162.cfg, custom/mvme162lx.cfg,
custom/mvme167.cfg, custom/ods68302.cfg, custom/sim68000.cfg,
custom/simcpu32.cfg, custom/uC5282.cfg: Change CCFLAGS to use the
-mcpu= option for Coldfires now supported in GCC 4.3.0.
2008-06-10 Matthew Riek <matthew.riek@ibiscomputer.com.au>
* custom/mcf52235.cfg: New.
* shared/m68kbspgetworkarea.c: Fix extern type to RamSize.
* shared/m68kpretaskinghook.c: Do not handle the RAM allocation if
the BSP is handling it.
* acinclude.m4: Add the mcf52235 BSP.
* include/bsp.h, irq/irq.c, irq/irq_init.c, startup/bspclean.c,
startup/bspstart.c: Slightly better names for IRQ benchmarking. Make
sure the routines are present all the time.
* started/buildc.t: Add paragraph on see CVS for latest patches.
* user/conf.t: Add CONFIGURE_MESSAGE_BUFFERS_FOR_QUEUE and example
of how to compute message CONFIGURE_MESSAGE_BUFFER_MEMORY using it.
* libcsupport/src/__times.c, libmisc/cpuuse/cpuusagereport.c,
libmisc/cpuuse/cpuusagereset.c, libmisc/monitor/mon-task.c,
rtems/include/rtems/rtems/ratemon.h, rtems/src/ratemongetstatus.c,
rtems/src/ratemonperiod.c, score/include/rtems/score/thread.h,
score/src/threaddispatch.c, score/src/threadinitialize.c,
score/src/threadtickletimeslice.c: Add typedefs for cpu usage and
period timing statistics. Also renamed related variables and
structure members so they are the same whether you are using
nanosecond (e.g. struct timespec) or ticks (e.g. uint32_t)
granularity. This lays the groundwork for future cleanup.
* 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.
* posix/src/psignal.c: Do not allocate any memory for queued signals if
the configuration parameter is 0. Before we would end up with an
allocation of 0 which rounded up and wasted some memory when POSIX
was configured.
* itron/include/rtems/itron/task.h, itron/src/task.c: ITRON currently
has no functional data in the user extension data area structure so
this disables the definition, allocation and deallocation of that
structure. If we ever have to add data to it, then it will be easy to
reenable.
* rtems/score/cpu.h: Add CPU_SIMPLE_VECTORED_INTERRUPTS porting
parameter to indicate that the port uses the Simple Vectored
Interrupt model or the Programmable Interrupt Controller Model. The
PIC model is implemented primarily in the BSP and it is responsible
for all memory allocation.
* sp28/init.c: Corrections to configuration.
* sp37/init.c: Correctly invoke rtems_interrupt_disable() body.
* spsize/size.c: _ISR_Vector_table only exists on architectures
which use the Simple Vectored Interrupt Model.
* score/src/objectgetinfo.c, score/src/objectidtoname.c,
score/src/threadget.c: Make sure the pointer to the API object table
is valid before derefencing it.
