  • cpu.c: Removed duplicate declaration for _ISR_Vector_table.
  • cpu_asm.S: Removed assembly language to vector ISR handler on MIPS ISA I. Now call mips_vector_isr_handlers() in libcpu or BSP.
  • rtems/score/cpu.h (CPU_INTERRUPT_NUMBER_OF_VECTORS): No longer a constant -- get the real value from libcpu.
  • Property mode set to 100644

10
11        * cpu_asm.h: Removed.
12        * Makefile.am: Remove cpu_asm.h.
13        * rtems/score/mips64orion.h: Renamed mips.h.
14        * rtems/score/mips.h: New file, formerly mips64orion.h.
15        Header rewritten.
16        (mips_get_sr, mips_set_sr, mips_enable_in_interrupt_mask,
17        mips_disable_in_interrupt_mask): New macros.
18        * rtems/score/Makefile.am: Reflect renaming mips64orion.h.
19        * asm.h: Include <mips.h> not <mips64orion.h>. Now includes the
20        few defines that were in <cpu_asm.h>.
21        * cpu.c (_CPU_ISR_Get_level): Added MIPS ISA I version of this routine.
22        MIPS ISA 3 is still in assembly for now.
23        (_CPU_Thread_Idle_body): Rewrote in C.
24        * cpu_asm.S: Rewrote file header.
25        (FRAME,ENDFRAME) now in asm.h.
26        (_CPU_ISR_Get_level): Removed ISA I version and rewrote in C.
27        (_CPU_ISR_Set_level): Removed ISA I version and rewrote in C.
28        (_CPU_Context_switch): MIPS ISA I now manages preserves SR_IEC and
29        leaves other bits in SR alone on task switch.
30        (mips_enable_interrupts,mips_disable_interrupts,
31        mips_enable_global_interrupts,mips_disable_global_interrupts,
32        disable_int, enable_int): Removed.
33        (mips_get_sr): Rewritten as C macro.
34        (_CPU_Thread_Idle_body): Rewritten in C.
35        (init_exc_vecs): Rewritten in C as mips_install_isr_entries() and
36        placed in libcpu.
37        (exc_tlb_code, exc_xtlb_code, exc_cache_code, exc_norm_code): Moved
38        to libcpu/mips/shared/interrupts.
39        (general): Cleaned up comment blocks and #if 0 areas.
40        * idtcpu.h: Made ifdef report an error.
41        * iregdef.h: Removed warning.
42        * rtems/score/cpu.h (CPU_INTERRUPT_NUMBER_OF_VECTORS): Now a variable
43        number defined by libcpu.
44        (_CPU_ISR_Disable, _CPU_ISR_Enable): Rewritten to use new routines
45        to access SR.
46        (_CPU_ISR_Set_level): Rewritten as macro for ISA I.
47        (_CPU_Context_Initialize): Honor ISR level in task initialization.
48        (_CPU_Fatal_halt): Use new _CPU_ISR_Disable() macro.

51
52        * rtems/score/cpu.h: When mips ISA level is 1, registers in the
53        context should be 32 not 64 bits.
54
552000-11-30      Joel Sherrill <joel@OARcorp.com>
56
57        * cpu_asm.S: Changed "_CPU_Ccontext_switch_restore: typo to
58        correct name of _CPU_Context_switch_restore.  Added dummy
59        version of exc_utlb_code() so applications would link.

62
63        * Makefile.am: Use ... instead of RTEMS_TOPdir in ACLOCAL_AMFLAGS.
64
652000-11-02      Ralf Corsepius <corsepiu@faw.uni-ulm.de>
66
67        * Makefile.am: Switch to ACLOCAL_AMFLAGS = -I $(RTEMS_TOPdir)/aclocal.
68
692000-10-25      Ralf Corsepius <corsepiu@faw.uni-ulm.de>
70
71        * Makefile.am: ACLOCAL_AMFLAGS= -I $(RTEMS_TOPdir)/macros.
72        Switch to GNU canonicalization.

76
77        * This is a major reworking of the mips64orion port to use
78        gcc predefines as much as possible and a big push to multilib
79        the mips port.  The mips64orion port was copied/renamed to mips
80        to be more like other GNU tools.  Alan did most of the technical
81        work of determining how to map old macro names used by the mips64orion
82        port to standard compiler macro definitions.  Joel did the merge
83        with CVS magic to keep individual file history and did the BSP
84        modifications. Details follow:
85        * Makefile.am: idtmon.h in mips64orion port not present.
86        * asm.h: MIPS64ORION replaced with MIPS. Frame setup macros added.
87        * cpu.c: Comments added.
88        * cpu_asm.S: Conditionals changed.  MIPS ISA level 1 support added.
89        First attempt at exception/interrupt processing for ISA level 1
90        and minus any use of IDT/MON added.
91        * idtcpu.h: Conditionals changed to use gcc predefines.
92        * iregdef.h: Ditto.
93        * cpu_asm.h: No real change.  Merger required commit.
94        * rtems/Makefile.am: Ditto.
95        * rtems/score/Makefile.am: Ditto.
96        * rtems/score/cpu.h: Change MIPS64ORION to MIPS.
97        * rtems/score/mips64orion.h: Change MIPS64ORION to MIPS.  Convert
98        from using RTEMS_CPU_MODEL to gcc predefines to figre things out.

101
102        * Makefile.am: Include compile.am.

106        * ChangeLog: New file.
