Now includes the - few defines that were in <cpu_asm.h>. - * cpu.c (_CPU_ISR_Get_level): Added MIPS ISA I version of this routine. - MIPS ISA 3 is still in assembly for now. - (_CPU_Thread_Idle_body): Rewrote in C. - * cpu_asm.S: Rewrote file header. - (FRAME,ENDFRAME) now in asm.h. - (_CPU_ISR_Get_level): Removed ISA I version and rewrote in C. - (_CPU_ISR_Set_level): Removed ISA I version and rewrote in C. - (_CPU_Context_switch): MIPS ISA I now manages preserves SR_IEC and - leaves other bits in SR alone on task switch. - (mips_enable_interrupts,mips_disable_interrupts, - mips_enable_global_interrupts,mips_disable_global_interrupts, - disable_int, enable_int): Removed. - (mips_get_sr): Rewritten as C macro. - (_CPU_Thread_Idle_body): Rewritten in C. - (init_exc_vecs): Rewritten in C as mips_install_isr_entries() and - placed in libcpu. - (exc_tlb_code, exc_xtlb_code, exc_cache_code, exc_norm_code): Moved - to libcpu/mips/shared/interrupts. - (general): Cleaned up comment blocks and #if 0 areas. - * idtcpu.h: Made ifdef report an error. - * iregdef.h: Removed warning. - * rtems/score/cpu.h (CPU_INTERRUPT_NUMBER_OF_VECTORS): Now a variable - number defined by libcpu. - (_CPU_ISR_Disable, _CPU_ISR_Enable): Rewritten to use new routines - to access SR. - (_CPU_ISR_Set_level): Rewritten as macro for ISA I. - (_CPU_Context_Initialize): Honor ISR level in task initialization. - (_CPU_Fatal_halt): Use new _CPU_ISR_Disable() macro. - -2000-12-06 Joel Sherrill <joel@OARcorp.com> - - * rtems/score/cpu.h: When mips ISA level is 1, registers in the - context should be 32 not 64 bits. - -2000-11-30 Joel Sherrill <joel@OARcorp.com> - - * cpu_asm.S: Changed "_CPU_Ccontext_switch_restore: typo to - correct name of _CPU_Context_switch_restore. Added dummy - version of exc_utlb_code() so applications would link. - -2000-11-09 Ralf Corsepius <corsepiu@faw.uni-ulm.de> - - * Makefile.am: Use ... instead of RTEMS_TOPdir in ACLOCAL_AMFLAGS. - -2000-11-02 Ralf Corsepius <corsepiu@faw.uni-ulm.de> - - * Makefile.am: Switch to ACLOCAL_AMFLAGS = -I $(RTEMS_TOPdir)/aclocal. - -2000-10-25 Ralf Corsepius <corsepiu@faw.uni-ulm.de> - - * Makefile.am: ACLOCAL_AMFLAGS= -I $(RTEMS_TOPdir)/macros. - Switch to GNU canonicalization. - -2000-10-24 Alan Cudmore <alanc@linuxstart.com> and - Joel Sherrill <joel@OARcorp.com> - - * This is a major reworking of the mips64orion port to use - gcc predefines as much as possible and a big push to multilib - the mips port. The mips64orion port was copied/renamed to mips - to be more like other GNU tools. Alan did most of the technical - work of determining how to map old macro names used by the mips64orion - port to standard compiler macro definitions. Joel did the merge - with CVS magic to keep individual file history and did the BSP - modifications. Details follow: - * Makefile.am: idtmon.h in mips64orion port not present. - * asm.h: MIPS64ORION replaced with MIPS. Frame setup macros added. - * cpu.c: Comments added. - * cpu_asm.S: Conditionals changed. MIPS ISA level 1 support added. - First attempt at exception/interrupt processing for ISA level 1 - and minus any use of IDT/MON added. - * idtcpu.h: Conditionals changed to use gcc predefines. - * iregdef.h: Ditto. - * cpu_asm.h: No real change. Merger required commit. - * rtems/Makefile.am: Ditto. - * rtems/score/Makefile.am: Ditto. - * rtems/score/cpu.h: Change MIPS64ORION to MIPS. - * rtems/score/mips64orion.h: Change MIPS64ORION to MIPS. Convert - from using RTEMS_CPU_MODEL to gcc predefines to figre things out. - -2000-09-04 Ralf Corsepius <corsepiu@faw.uni-ulm.de> - - * Makefile.am: Include compile.am. - -2000-08-10 Joel Sherrill <joel@OARcorp.com> - - * ChangeLog: New file. |
