* 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.
* rtems/asm.h, rtems/score/cpu.h: cpu.h defines were not available to
assembly programs. This resulted in percpu.h (when included from
assembly) not being able to detect that the MIPS does not have a
dedicated software managed interrupt stack.
PR 1573/cpukit
* cpu_asm.S, 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.
PR 1385/cpukit
* cpu_asm.S: When the type rtems_boolean was switched to the C99 bool,
the size changed from 4 bytes to 1 byte. The interrupt dispatching
code accesses two boolean variables for scheduling purposes and the
assembly implementations of this code did not get updated.
* 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: Use a constant for CPU_STACK_MINIMUM_SIZE so it
can be used in cpp expressions. Using sizeof() requires actually
compiling the file.
* cpu.c, rtems/score/cpu.h: 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.
* rtems/score/cpu.h: 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.
* rtems/score/cpu.h: Eliminate the clicks_per_microsecond field in the
MIPS CPU Table and define another mechanism for drivers to obtain
this information.
* rtems/score/cpu.h: Part of a large patch to improve Doxygen output.
As a side-effect, grammar and spelling errors were corrected, spacing
errors were address, and some variable names were improved.
