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.
2010-06-16 Joel Sherrill <joel.sherrilL@OARcorp.com>
* cpu_asm.S: Use SYM macro to be consistent with other ports.
2010-04-20 Allan Hessenflow <allanh@kallisti.com>
* cpu_asm.S: L0-L3 were part of the interrupt context, but as
Mike Frysinger noted they were not being zeroed before calling
the C handlers. A patch that corrects this, as well as improving
some of the push/pop order to avoid stalls.
2010-04-17 Allan Hessenflow <allanh@kallisti.com>
* cpu.c, cpu_asm.S, rtems/score/cpu.h: Fine tune registers saved in the
context. The sp and imask registers need to be saved. Also allocated
12 bytes on the stack at thread entry as the abi requires that.
2010-04-17 Mike Frysinger <vapier.adi@gmail.com>
* cpu.c: Blackfin ABI requires L registers to be 0 upon function entry.
2010-03-27 Joel Sherrill <joel.sherrill@oarcorp.com>
* Makefile.am: Remove unused file.
* irq.c: Removed.
2009-05-25 Allan Hessenflow <allanh@kallisti.com>
PR 1417/cpukit
* rtems/score/cpu.h: corrected _CPU_ISR_Flash implementation, added
core synchronization after all cli/sti.
2009-03-12 Joel Sherrill <joel.sherrill@OARcorp.com>
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.
2009-02-12 Joel Sherrill <joel.sherrill@oarcorp.com>
* cpu.c, rtems/score/cpu.h: Change prototype of IDLE thread to
consistently return void * and take a uintptr_t argument.
2009-02-11 Joel Sherrill <joel.sherrill@oarcorp.com>
* cpu.c, rtems/score/cpu.h: Eliminate _CPU_Thread_dispatch_pointer and
passing address of _Thread_Dispatch to _CPU_Initialize. Clean up
comments.
2008-09-11 Ralf Corsépius <ralf.corsepius@rtems.org>
* rtems/score/types.h: Do not define boolean, single_precision,
double_precision unless RTEMS_DEPRECATED_TYPES is given.
2008-09-08 Joel Sherrill <joel.sherrill@oarcorp.com>
* cpu.c: Remove extraneous spaces.
2008-09-05 Ralf Corsépius <ralf.corsepius@rtems.org>
* cpu.c, rtems/score/cpu.h: Convert to "bool".
2008-08-21 Ralf Corsépius <ralf.corsepius@rtems.org>
* rtems/score/types.h: Include stdbool.h.
Use bool as base-type for boolean.
2008-08-15 Joel Sherrill <joel.sherrill@OARcorp.com>
* ChangeLog: Add correct entry.
2008-08-13 Allan Hessenflow <allanh@kallisti.com>
* cpu.c, cpu_asm.S, irq.c, rtems/score/cpu.h,
rtems/score/cpu_asm.h: reworked interrupt handling to fix
context switching.
2008-07-31 Joel Sherrill <joel.sherrill@OARcorp.com>
* rtems/score/cpu.h: Correct prototype of Idle threads.
2008-06-05 Joel Sherrill <joel.sherrill@OARcorp.com>
* 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.
2007-12-20 Joel Sherrill <joel.sherrill@OARcorp.com>
* rtems/score/cpu.h: Use correct register name.
2007-12-17 Joel Sherrill <joel.sherrill@oarcorp.com>
* rtems/score/cpu.h: Add _CPU_Context_Get_SP() for stack check utility.
2007-12-17 Joel Sherrill <joel.sherrill@OARcorp.com>
* cpu.c, irq.c, rtems/score/cpu_asm.h: Sweep to make sure grep for
COPYRIGHT passes.
2007-12-04 Joel Sherrill <joel.sherrill@OARcorp.com>
* 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.
2007-12-03 Joel Sherrill <joel.sherrill@OARcorp.com>
* 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.
2007-09-10 Alain Schaefer <alani@easc.ch>
* cpu_asm.S: Fix two problems:
- CC bit has been clobbered and was not correctly restored
- bfin hardware does not allow to read instructions from the L1
2007-09-10 Alain Schaefer <alani@easc.ch>
* rtems/bfin/bf533.h: Add more definitions.
2007-05-31 Alain Schaefer <alani@easc.ch>
* rtems/score/cpu.h: Modifiy inline assembly language
constraints to use a data register as the CTL/STI
instructions requires. This is not only more correct,
it avoids GCC PR31787.
2007-05-24 Alain Schaefer <alani@easc.ch>
* rtems/score/cpu.h: Fix incorrect interrupt mask.
2007-04-17 Joel Sherrill <joel@OARcorp.com>

2007-04-17 Ralf Corsépius <ralf.corsepius@rtems.org>

Use Context_Control_fp* instead of void* for fp_contexts.
Eliminate evil casts.
2006-11-17 Ralf Corsépius <ralf.corsepius@rtems.org>
