3
        * src/powerpc.ld:
4
        Added .eh_frame to data section. This is a stopgap fix to allow
5
        C++ programs that define exceptions to link and run. It does not
6
        allow them to actually throw exceptions, since that depends on
7
        compiler changes that have not been made. Further, more
8
        far-reaching, linker script changes will also be needs when that
9
        happens.
10
        Added libsupc++.a to GROUP() directive for GCC versions later than
11
        3.0.
12
2003-01-03  Gary Thomas  
13
 
14
        * include/hal_mem.h (CYGARC_MEMDESC_NOCACHE_PA): New macro which
15
        allows defining non-cached space with non 1-1 mapping.
16
 
17
2002-12-24  Gary Thomas  
18
 
19
        * src/vectors.S:
20
        * cdl/hal_powerpc.cdl: Add option to allow ROM code to simply
21
        jump to the startup code, instead of using an absolute address.
22
 
23
2002-11-14  Gary Thomas  
24
 
25
        * src/vectors.S: Provide pointer to saved registers on interrupt.
26
        This is necessary for profiling support.
27
 
28
2002-11-13  Gary Thomas  
29
 
30
        * src/hal_misc.c (hal_enable_caches): Support new CDL options for
31
        how [mode] to enable DATA cache.
32
 
33
2002-08-05  Gary Thomas  
34
2002-08-05  Bob Koninckx 
35
 
36
        * include/arch.inc: hal_fpu_load regs was not loading registers!
37
 
38
2002-08-01  Gary Thomas  
39
 
40
        * include/hal_io.h:
41
        * include/hal_intr.h: Allow more variant/platform overrides.
42
 
43
2002-04-29  Jonathan Larmour  
44
 
45
        * src/vectors.S:
46
        Don't use .file as it can confuse debugging since the .file
47
        doesn't contain the path and therefore the debugger will never
48
        know where it lives! This conflicts with using -Wa,--gstabs.
49
 
50
2002-04-25  Jonathan Larmour  
51
 
52
        * src/ppc_stub.c (__computeSignal): Only handle ITLB/DTLB MISS if
53
        defined by platform.
54
 
55
2002-04-24  Bob Koninckx 
56
2002-04-24  Jonathan Larmour  
57
 
58
        * include/hal_arch.h (HAL_SavedRegisters): Add FP regs.
59
        * include/arch.inc: Add FPU register names.
60
        Implement hal_fpu_save and hal_fpu_load.
61
        * src/context.S: save/restore FP regs.
62
        * src/hal_mk_defs.c (main): Export CYGARC_JMPBUF_F* for FPU regs.
63
        * src/ppc_stub.c (__computeSignal): SW_EMUL is support by 5xx.
64
        ITLB and DTLB MISS only supported by 8xx.
65
        * cdl/hal_powerpc.cdl (CYGHWR_HAL_POWERPC_VECTOR_BASE): Take
66
        CYGHWR_HAL_POWERPC_FORCE_VECTOR_BASE_LOW into account.
67
 
68
2002-04-11  Gary Thomas  
69
 
70
        * src/hal_misc.c (hal_enable_caches): Chance cache handling & setup to
71
        be controlled by common CDL (like other platforms/architectures).
72
 
73
        * src/hal_intr.c (hal_delay_us): Didn't work if there are less than
74
        one decrementer tick per micro-second.  Used a calculation that seems
75
        to work no matter how the decrementer is configured.
76
 
77
2002-04-08  Gary Thomas  
78
 
79
        * src/vectors.S (_hal_hardware_init_done): Can't copy vectors until
80
        DRAM is setup (like the comment said all along).
81
 
82
2002-03-08  Gary Thomas  
83
 
84
        * src/vectors.S (_hal_hardware_init_done): New label - used by
85
        ROMRAM code to figure out relative addressing.
86
 
87
2002-01-23  Gary Thomas  
88
 
89
        * src/hal_mk_defs.c (main): Clean up compile warning.
90
 
91
2001-11-16  Nick Garnett  
92
 
93
        * include/hal_arch.h (HAL_MSBIT_INDEX): Fixed this macro so that
94
        it actually works!
95
 
96
2001-11-15  Jesper Skov  
97
 
98
        * src/hal_misc.c (hal_arch_default_isr): Added return
99
        statement (found by Christoph Csebits).
100
 
101
2001-02-23  Jesper Skov  
102
 
103
        * src/powerpc.ld: Added .2ram section matching to .data section.
104
 
105
2001-02-05  Jesper Skov  
106
 
107
        * src/ppc_stub.c (__computeSignal): Hack to allow thread debugging
108
        on 40x cores.
109
 
110
2001-01-24  Jesper Skov  
111
 
112
        * src/powerpc.ld: Added .sdata to .sdata pattern.
113
 
114
2001-01-16  Gary Thomas  
115
 
116
        * src/vectors.S (_start): Set up IRQ environment _before_ calling
117
        constructors - since they may need it to work.
118
 
119
2001-01-15  Gary Thomas  
120
 
121
        * src/ppc_stub.c: Define new method for achieving single stepping
122
        when processor (like 40x) does not support it in hardware.  This
123
        method will be invoked if the variant or plaform define the
124
        symbol CYGNUM_HAL_NO_VECTOR_TRACE.
125
 
126
2001-01-03  Gary Thomas  
127
 
128
        * src/hal_intr.c (hal_delay_us): Fix some problems - didn't
129
        always work properly, especially on fast processors.
130
 
131
2000-11-21  Gary Thomas  
132
 
133
        * src/vectors.S (rom_vectors): Special handling when vectors
134
        can't be easily aligned, etc. (Work around messy hardware).
135
 
136
2000-11-04  Gary Thomas  
137
 
138
        * src/vectors.S: Minor changes in support of PPC40x.  This
139
        platform has no cache control - if the MMU is on, it's on.
140
        This causes some interesting cache coherency problems in the
141
        interrupt/exception handlers.  Note: it may be possible to
142
        overcome this by use of the DCCR register (untested).
143
 
144
        * src/powerpc.ld: Fix problems with 'sbss6', etc.
145
 
146
        * src/hal_mk_defs.c: Use variant/platform macros for additional
147
        symbols, rather than direcly polluting this file.
148
 
149
        * include/hal_intr.h: Allow variant/platform to define clock
150
        setup (since the 40x does not have a decrementer!)
151
 
152
2000-10-31  Jonathan Larmour  
153
 
154
        * src/powerpc.ld: Use .sdata.* rather than .sdata* so that .sdata2
155
        doesn't get matched so that the linker script symbols are still valid.
156
        Ditto for .sbss*.
157
 
158
2000-10-24  Jonathan Larmour  
159
 
160
        * src/powerpc.ld: Match multiple sections where relevant (.bss*,
161
        .sbss*, .sdata*, etc.)
162
 
163
2000-10-20  Jesper Skov  
164
 
165
        * src/hal_misc.c: Update __mem_fault_handler declaration.
166
 
167

175
        in terms of this.

192
        Switched to new table definition mechanism.
193
 
194
        * include/basetype.h: Removed definition of CYG_LABEL_NAME().

217
        to variant idle functions which now get called.
218
        (hal_enable_caches): Moved serialization code to 8xx variant init.
219
 
220
        * src/vectors.S (restore_state): Use hal_fpu_load and

232
 
233
        * include/hal_intr.h (HAL_CLOCK_RESET): Prevent warning
234
        (patch thanks to Sergei Organov (osv at javad.ru))
235

238
        * include/hal_intr.h (HAL_CLOCK_RESET): Add to decrementer instead

        CYGSEM_HAL_POWERPC_COPY_VECTORS.
257
 
258
2000-02-29  Gary Thomas  
259
 
260
        * src/vectors.S (_start): Actually copy exception vectors if
261
        "copy vectors" selected and not running from ROM (useful if

266
        * cdl/hal_powerpc.cdl: Add copy vectors option.

        * src/vectors.S: Leave out vectors if they are not used. Also
268
        clean up r1/sp usage.

275
        interrupt_end code. restore_state and

349
2000-02-07  Jesper Skov

470
        * include/hal_intr.h (CYGNUM_HAL_EXCEPTION_DATA_ACCESS): Define
471
        this for handling MACHINE_CHECK if an MPC860 - it never generates
472
        ISI nor DSI exceptions, only machine check.  This allows libc to
473
        catch SEGVs from this unexpected quarter.

477
        * include/ppc_regs.h: Add proper definitions of timebase regs.
478
 
479
        * tests/intr0.c: Add some useful debugging printouts and recording
480
        of state, and make more platform-portable; the rate of PTA is not
481
        always 1:32 wrt the timebase.

486
        next note).
487
 
488
        * src/hal_intr.c (hal_IRQ_init): New platform dependent function
489
        used to setup whatever is necessary to handle interrupts.
490
        Add basic "wiring" of CPM to SIU interrupts.
491
 
492
        * include/hal_intr.h: Fix CPM interrupt macros - control register
493
        is 32 bits, not 16.

499
1999-06-24  Hugo Tyson  
500
 
501
        * src/hal_misc.c (cyg_hal_exception_handler): If the decrementer
502
        has underflowed when we are returning from an exception, then we
503
        reset it here; this is harmless if all is well, and required if
504
        the QUICC-equipped MPC860 is getting confused about interrupts
505
        following an exception.  Only in QUICC configurations.
506
 
507
1999-06-22  Hugo Tyson  
508
 
509
        * src/vectors.S (_start): Support breaking back into the stub ROM
510
        when we see a breakpoint, if RAM start and RAM-based vectors for
511
        the stub.  Rather than using a direct jump, instead skip copying
512
        the program exception vectors - leave the stub's vec in place.
513
        Controlled by CYGPRI_STUBROM_HAS_RAM_VECTORS, which varies from
514
        platform to platform.

        the better to accommodate differing platform requirements viz a
520
        viz cache enabling and so on.
521
 
522
1999-06-17  Hugo Tyson  
523
 
524

527
1999-06-15  Hugo Tyson  
528

530
        They are needed by platform code.

538
        platform HAL.
539
 
540
        * src/hal_misc.c: remove very-platform-conditional definition of
541
        memory descriptor table - it is now in platform HALs.
542
 
543
        * include/ppc_regs.h: simplify definition of CYGARC_REG_IMM_BASE.
544
 
545
        * include/hal_cache.h (CYGARC_MEMDESC_CACHE): ...and other
546
        macros... add support for external definitions of memory
547
        descriptor table used in platform-specific initialization of MMU.

        reorganized and renamed into the FADS component.
556
 
557
        * include/quicc_smc.h, src/ppc_860.h, src/quicc_smc.c: removed;

559
 
560
        * src/hal_misc.c (hal_idle_thread_action): Add some useful

562
        disabled, so no effect on code.
563
 
564
        * include/ppc_regs.h: Different default value for
565

566
        This is a temporary measure.
