        deadlock caused by interrupt arriving while dispatching.

2002-07-05      Ralf Corsepius 

        * configure.ac: RTEMS_TOP(../../../..).

        * Makefile.am: Reflect changes above.

2002-07-01      Ralf Corsepius 

        * configure.ac: Remove RTEMS_PROJECT_ROOT.

2002-06-27      Ralf Corsepius 

        * configure.ac: Add RTEMS_PROG_CCAS

2002-06-27      Ralf Corsepius

        Add AC_PROG_RANLIB.

2002-06-17      Ralf Corsepius 

        * Makefile.am: Include $(top_srcdir)/../../../automake/*.am.

        Use ../../../aclocal.

2001-04-03      Joel Sherrill 

        * Per PR94, all rtems/score/CPUtypes.h are named rtems/score/types.h.

        * rtems/score/mipstypes.h: Removed.

        * rtems/score/types.h: New file via CVS magic.

        * Makefile.am, rtems/score/cpu.h: Account for name change.

2002-03-27      Ralf Corsepius 

        * configure.ac:

        AC_INIT(package,_RTEMS_VERSION,_RTEMS_BUGS).

        AM_INIT_AUTOMAKE([no-define foreign 1.6]).

        * Makefile.am: Remove AUTOMAKE_OPTIONS.

2002-03-20      Greg Menke 

        * cpu_asm.S: Now compiles on 4600 and 4650.

2002-03-13      Greg Menke 

        * cpu_asm.S: Fixed a sneaky return from int w/ ints disabled bug.

        * rtems/score/cpu.h: Fixed register numbering in comments and made

        interrupt enable/disable more robust.

2002-03-05      Greg Menke 

        * cpu_asm.S: Added support for the debug exception vector, cleaned

        up the exception processing & exception return stuff.  Re-added

        EPC in the task context structure so the gdb stub will know where

        a thread is executing.  Should've left it there in the first place...

        * idtcpu.h: Added support for the debug exception vector.

        * cpu.c: Added ___exceptionTaskStack to hold a pointer to the

        stack frame in an interrupt so context switch code can get the

        userspace EPC when scheduling.

        * rtems/score/cpu.h: Re-added EPC to the task context.

2002-02-27      Greg Menke 

        * cpu_asm.S: Fixed exception return address, modified FP context

        switch so FPU is properly enabled and also doesn't screw up the

        exception FP handling.

        * idtcpu.h: Added C0_TAR, the MIPS target address register used for

        returning from exceptions.

        * iregdef.h: Added R_TAR to the stack frame so the target address

        can be saved on a per-exception basis.  The new entry is past the

        end of the frame gdb cares about, so doesn't affect gdb or cpu.h

        stuff.

        * rtems/score/cpu.h: added an #ifdef so cpu_asm.S can include it

        to obtain FPU defines without syntax errors generated by the C

        defintions.

        * cpu.c: Improved interrupt level saves & restores.

2002-02-08      Joel Sherrill 

        * iregdef.h, rtems/score/cpu.h: Reordered register in the

        exception stack frame to better match gdb's expectations.

2001-02-05      Joel Sherrill 

        * cpu_asm.S: Enhanced to save/restore more registers on

        exceptions.

        * rtems/score/cpu.h (CPU_Interrupt_frame): Enhanced to list every

        register individually and document when it is saved.

        * idtcpu.h: Added constants for the coprocessor 1 registers

        revision and status.

2001-02-05      Joel Sherrill 

        * rtems/Makefile.am, rtems/score/Makefile.am: Removed again.

2001-02-04      Joel Sherrill 

        * rtems/score/cpu.h: IDLE task should not be FP.  This was a mistake

        in the previous patch that has now been confirmed.

2001-02-01      Greg Menke 

        * cpu.c: Enhancements and fixes for modifying the SR when changing

        the interrupt level.

        * cpu_asm.S: Fixed handling of FP enable bit so it is properly

        managed on a per-task basis, improved handling of interrupt levels,

        and made deferred FP contexts work on the MIPS.

        * rtems/score/cpu.h: Modified to support above changes.

2002-01-28      Ralf Corsepius 

        * rtems/Makefile.am: Removed.

        * rtems/score/Makefile.am: Removed.

        * configure.ac: Reflect changes above.

        * Makefile.am: Reflect changes above.

2002-02-09      Ralf Corsepius 

        * asm.h: Remove #include .

        Add #include .

        * configure.ac: Remove RTEMS_CHECK_CUSTOM_BSP(RTEMS_BSP).

2001-12-20      Ralf Corsepius 

        * configure.ac: Use RTEMS_ENV_RTEMSCPU.

2001-12-19      Ralf Corsepius 

        * Makefile.am: Add multilib support.

2001-11-28      Joel Sherrill ,

        This was tracked as PR91.

        * rtems/score/cpu.h: Added CPU_PROVIDES_ISR_IS_IN_PROGRESS macro which

        is used to specify if the port uses the standard macro for this (FALSE).

        A TRUE setting indicates the port provides its own implementation.

2001-10-12      Joel Sherrill 

        * cpu_asm.S: _CPU_Context_save_fp in was incorrectly in conditional

        compilation block with (CPU_HARDWARE_FP == FALSE).  Reported by

        Wayne Bullaughey .

2001-10-11      Ralf Corsepius 

        * .cvsignore: Add autom4te.cache for autoconf > 2.52.

        * configure.in: Remove.

        * configure.ac: New file, generated from configure.in by autoupdate.

2001-09-23      Ralf Corsepius 

        * rtems/score/Makefile.am: Use 'PREINSTALL_FILES ='.

        * Makefile.am: Use 'PREINSTALL_FILES ='.

2001-07-03      Joel Sherrill 

        * cpu.c: Fixed typo.

2000-05-24      Joel Sherrill 

        * rtems/score/mips.h: Added constants for MIPS exception numbers.

        All exceptions should be given low numbers and thus can be installed

        and processed in a uniform manner.  Variances between various MIPS

        ISA levels were not accounted for.

2001-05-24      Greg Menke 

        * Assisted in design and debug by Joel Sherrill .

        * cpu_asm.S: Now works on Mongoose-V.  Missed in previous patch.

2001-05-22      Greg Menke 

        * rtems/score/cpu.h: Add the interrupt stack structure and enhance

        the context initialization to account for floating point tasks.

        * rtems/score/mips.h: Added the routines mips_set_cause(),

        mips_get_fcr31(), and mips_set_fcr31().

        * Assisted in design and debug by Joel Sherrill .

2001-05-07      Joel Sherrill 

        * cpu_asm.S: Merged patches from Gregory Menke

         that clean up

        stack usage and include nops in the delay slots.

2001-04-20      Joel Sherrill 

        * cpu_asm.S: Added code to save and restore SR and EPC to

        properly support nested interrupts.  Note that the ISR

        (not RTEMS) enables interrupts allowing the nesting to occur.

2001-03-14      Joel Sherrill 

        * cpu.c, rtems/score/cpu.h, rtems/score/mipstypes.h:

        Removed unused variable _CPU_Thread_dispatch_pointer

        and cleaned numerous comments.

2001-03-13      Joel Sherrill 

        * cpu.c, cpu_asm.S, iregdef.h, rtems/score/cpu.h, rtems/score/mips.h:

        Merged MIPS1 and MIPS3 code reducing the number of lines of assembly.

        Also reimplemented some assembly routines in C further reducing

        the amount of assembly and increasing maintainability.

2001-02-04      Ralf Corsepius 

        * Makefile.am, rtems/score/Makefile.am:

        Apply include_*HEADERS instead of H_FILES.

2001-01-12      Joel Sherrill 

        * rtems/score/mips.h (mips_get_sr, mips_set_sr): Corrected

        register constraints from "general" to "register".

2001-01-09      Joel Sherrill 

        * cpu_asm.S: Use SR_INTERRUPT_ENABLE_BITS instead of SR_XXX constants

        to make it easier to conditionalize the code for various ISA levels.

2001-01-08      Joel Sherrill 

        * idtcpu.h: Commented out definition of "wait".  It was stupid to

        use such a common word as a macro.

        * rtems/score/cpu.h (_CPU_ISR_Disable): Fixed for mips ISA 3.

        * rtems/score/mips.h: Added include of .

        * rtems/score/mips.h (mips_enable_in_interrupt_mask): Corrected.

2001-01-03      Joel Sherrill 

        * rtems/score/cpu.h: Added _CPU_Initialize_vectors().

        * cpu_asm.S: Eliminated warning for duplicate definition of EXTERN.

2000-12-19      Joel Sherrill 

        * cpu_asm.S (_ISR_Handler): Return to the address in the EPC register.

        Previous code resulting in the interrupted immediately returning

        to the caller of the routine it was inside.

2000-12-19      Joel Sherrill 

        * cpu.c (_CPU_Initialize): Do not initialize _ISR_Vector_table() here

        because it has not been allocated yet.

2000-12-13      Joel Sherrill 

        * 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.

2000-12-13      Joel Sherrill 

        * cpu_asm.h: Removed.

        * Makefile.am: Remove cpu_asm.h.

        Header rewritten.

        (mips_get_sr, mips_set_sr, mips_enable_in_interrupt_mask,

        mips_disable_in_interrupt_mask): New macros.

        * rtems/score/Makefile.am: Reflect renaming mips64orion.h.

        * asm.h: Include  not . Now includes the

        few defines that were in .

        * cpu.c (_CPU_ISR_Get_level): Added MIPS ISA I version of this routine.

        MIPS ISA 3 is still in assembly for now.

        * 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.

2000-12-06      Joel Sherrill 

        * 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 

        * 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 

        * Makefile.am: Use ... instead of RTEMS_TOPdir in ACLOCAL_AMFLAGS.

2000-11-02      Ralf Corsepius

        Switch to GNU canonicalization.

2000-10-24      Alan Cudmore  and

        Joel Sherrill 

        * 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 

        * Makefile.am: Include compile.am.

2000-08-10      Joel Sherrill 

        * ChangeLog: New file.
