Without the source the error code does not say that much.
Let it be up to the CPU/BSP to determine the error code
reported on fatal shutdown.
This patch does not change the current behaviour, just
adds the option to handle the source of the fatal halt.

Add a CPU counter interface to allow access to a free-running counter.
It is useful to measure short time intervals. This can be used for
example to enable profiling of critical low-level functions.
Add two busy wait functions rtems_counter_delay_ticks() and
rtems_counter_delay_nanoseconds() implemented via the CPU counter.

This commit deletes all RTEMS ChangeLog files. These files have been abandoned
since converting to git version control. The historical data may be recovered
by checking out any commit before this one. Most of the contents of these
ChangeLog files can also be found in the git log.
Two external ChangeLog files, ChangeLog.slac and ChangeLog.zlib, remain.

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

Add CPU port type CPU_Exception_frame and function
_CPU_Exception_frame_print().
The CPU ports of avr, bfin, h8300, lm32, m32c, m32r, m68k, nios2, sh,
sparc64, and v850 use an empty default implementation of
_CPU_Exception_frame_print().
Add rtems_exception_frame and rtems_exception_frame_print().
Add RTEMS_FATAL_SOURCE_EXCEPTION for CPU exceptions. Use rtems_fatal()
with source RTEMS_FATAL_SOURCE_EXCEPTION in CPU ports of i386, powerpc,
and sparc for unexpected exceptions.
Add third parameter to RTEMS_BSP_CLEANUP_OPTIONS() which controls the
BSP_PRINT_EXCEPTION_CONTEXT define used in the default
bsp_fatal_extension().
Add test sptests/spfatal26.

Add and use new CPU port define CPU_SIZEOF_POINTER. It must be an
integer literal that can be used by the assembler. This value will be
used to calculate offsets of structure members. These offsets will be
used in assembler code.
The size of a pointer is part of the application binary interface (ABI)
and thus independent of the actual programming language. The compiler
will provide defines to determine the current ABI. We use these defines
to select the appropriate CPU_SIZEOF_POINTER value.
Static assertions in the new file "cpukit/score/src/percpuasm.c" will
ensure that the value of CPU_SIZEOF_POINTER is consistent with the
current compiler settings. Also the offset values used by assembler
code are verfied.

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.

PR 1914/cpukit
* rtems/score/cpu.h: Select timestamp implementation.

|
|
| |
* cpu.c: Remove /*PAGE markers which were interpreted by a long dead
print script.
|

* Makefile.am: Reformat.
|
|

* context.c, cpu.c, rtems/score/cpu.h, rtems/score/sh.h:
Use "__asm__" instead of "asm" for improved c99-compliance.
|
|
|
|
|
|

* rtems/score/cpu.h: Add RTEMS_COMPILER_NO_RETURN_ATTRIBUTE to
_CPU_Context_restore() because it does not return. Telling GCC this
avoids generation of dead code.

PR 1635/cpukit
* rtems/score/cpu.h, rtems/score/types.h: Refactoring of priority
handling, to isolate the bitmap implementation of priorities in the
supercore so that priority management is a little more modular. This
change is in anticipation of scheduler implementations that can
select how they manage tracking priority levels / finding the highest
priority ready task. Note that most of the changes here are simple
renaming, to clarify the use of the bitmap-based priority management.

PR 1573/cpukit
* rtems/score/cpu.h: Add a per cpu data structure which contains the
information required by RTEMS for each CPU core. This encapsulates
information such as thread executing, heir, idle and dispatch needed.
|
|
|
|
| |
* cpu.c: Warning removal.
|
|
|
|
| |
* context.c, cpu.c: Add include of config.h
|

* rtems/score/sh.h: SH2E and SH3E have a DSP rather than an FPU. They
are not compatible. We currently only support the FPU found on the
SH3 and SH4.
|
|
|
|
|
| |
* cpu.c, rtems/score/cpu.h: Change prototype of IDLE thread to
consistently return void * and take a uintptr_t argument.
|
|
|
|
|
|
| |
* cpu.c, rtems/score/cpu.h: Eliminate _CPU_Thread_dispatch_pointer and
passing address of _Thread_Dispatch to _CPU_Initialize. Clean up
comments.
|

* cpu.c: Fine tune conditional so _CPU_ISR_install_vector is in CPU Kit
now.
|
|
|
|
|
|

* Makefile.am: Move duplicated context switch code to score/cpu. This
has been used to run tests on the simulator BSP as SH1, SH2, and SH4.
* context.c: New file.
|
|
|
|
|
| |
* rtems/score/types.h: Do not define boolean, single_precision,
double_precision unless RTEMS_DEPRECATED_TYPES is given.
|
|
|
|

* cpu.c: Remove extraneous spaces.
|
|
|
|

* rtems/score/types.h: Include stdbool.h.
Use bool as base-type for boolean.

|
|

* rtems/score/cpu.h: Add missing prototype.
|
| |
|
|
|

* cpu.c, rtems/score/cpu.h: Correct prototype of Idle threads.
|
|
|
|
|
|
|
|
| |
* 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.
|
|
|
|
| |
* rtems/score/cpu.h: Add _CPU_Context_Get_SP() for stack check utility.
