  • new-exceptions/bspsupport/vectors_init.c: must not align start of stack downwards (we don't 'own' memory below start). Instead, use original boundaries but align the stack pointer as required.

Added test to verify that R13 was loaded with _SDA_BASE_
during early initialization (low-level assembly code
relies on it).
  • Property mode set to 100644

13
14        * new-exceptions/cpu.c: propagate R2 to all task contexts
15        even if the ABI is SVR4. Cannot hurt...
16

18
19        * new-exceptions/cpu.c: use ppc_interrupt_get_disable_mask()
20        to determine which bits to set/clear from _CPU_Context_Initialize().
21
222008-07-16      Till Straumann <strauman@slac.stanford.edu>
23
24        * new-exceptions/bspsupport/ppc_exc_asm_macros.h: Added
25        a test to TEST_LOCK_crit so that a context switch is
26        always prevented if MSR_CE is not set in the interrupt mask.
27        (Support mode where the user wants to leave MSR_CE always enabled
28        but abstains from calling OS primitives from the exception
29        handler.)

57        sections.
58
59        * rtems/powerpc/powerpc.h, shared/src/cache.c, shared/src/cache_.h:
60        New defines PPC_NO_CACHE_ALIGNMENT and PPC_NO_CACHE_ALIGNMENT_POWER for
61        CPUs with no cache.  Provide default implementations for all cache
62        functions.

65
662008-07-14      Thomas Doerfler <thomas.doerfler@embedded-brains.de>
67
68        * Makefile.am, new-exceptions/raw_exception.c,
69        * new-exceptions/bspsupport/irq.c, ppc403/clock/clock_4xx.c,
70        * ppc403/include/ppc405ex.h, ppc403/include/ppc405gp.h,
71        * ppc403/timer/timer.c, rtems/powerpc/powerpc.h,
72        * shared/include/cpuIdent.c, shared/include/cpuIdent.h,
73        * shared/include/powerpc-utility.h:
74        Added support for PPC405EX (contributed by Michael Hamel)
75       
762008-07-11      Sebastian Huber <sebastian.huber@embedded-brains.de>
77
78        * Makefile.am: Install powerpc-utility.h.
79
80        * shared/include/cpuIdent.h, shared/include/cpuIdent.c: Added e200 and
81        e300 features.
82
83        * new-exceptions/cpu.c: Removed PR288 bugfix check.
84
85        * new-exceptions/e500_raw_exc_init.c: Added initialization for e200.
86        Set IVPR register for e200 and e500 to ppc_exc_vector_base.
87
88        * new-exceptions/raw_exception.c, new-exceptions/raw_exception.h: Added
89        vector categories for e200 and e300 cores.  Added global variable
90        ppc_exc_vector_base for CPUs with IVPR register.
91
92        * new-exceptions/bspsupport/ppc_exc.S,
93        * new-exceptions/bspsupport/ppc_exc_asm_macros.h,
94        * new-exceptions/bspsupport/ppc_exc_bspsupp.h,
95        * new-exceptions/bspsupport/ppc_exc_hdl.c,
96        * new-exceptions/bspsupport/vectors.h,
97        * new-exceptions/bspsupport/vectors_init.c:
98        Conistent code layout in most assember code sections and usage of
99        defines for registers.  Usage of standard header files to avoid
100        multiple definitions.
101       
102        Optimized exception code: Removed many branches and exploit branch
103        prediction for asynchronous exceptions, moved common wrap code into
104        WRAP macro to eliminate branch, static initialization of the handler
105        table with a default handler to eliminate the test if a handler is
106        present.  Register CR6 is no more cleared because the exeption handler
107        functions are not variadic.
108       
109        New method to switch to the interrupt stack. It will be tested if the
110        exception stack pointer is already inside the interrupt stack area.  It
111        is no more necessary to disable interrupts.  The SPRG1 and SPRG2 are
112        used to store the initial interrupt stack pointer and the interrupt
113        stack memory area start.
114
115        Removed variable ppc_exc_msr_irq_mask and use general interrupt disable
116        mask from SPRG0 instead.
117
118        New initialization routine ppc_exc_initialize() for bsp_start().  It
119        takes the interrupt disable mask, interrupt stack start and size as
120        parameters.
121
122        Added packed prologues for CPUs with IVPR and IVOR registers to save
123        memory space.
124
125        Reverted ppc_exc_crit_always_enabled change from yesterday.
126
127        WARNING: Tests with critical interrupt exceptions crash the system at
128        least on MPC8313ERDB and MPC8349EAMDS.  There may be somewhere a
129        serious bug with the new code.
130
1312008-07-10      Till Straumann <strauman@slac.stanford.edu>
132
133        * mpc6xx/mmu/pte121.c: use general "memory" clobber
134        rather than memory input operand in inline assembly
135        ("m" doesn't do what the manual says; see discussion
136        on gcc mailing list around 2008/3/30)
137
1382008-07-10      Till Straumann <strauman@slac.stanford.edu>
139
140        * ChangeLog, mpc8xx/clock/clock.c, ppc403/clock/clock.c,
141        ppc403/irq/ictrl.h, rtems/powerpc/powerpc.h:
142        Removed all macro definitions which depended on
143        the compiler defining a PPC CPU-model dependent
144        symbol from files in cpukit.
145        Macros which were not used by cpukit have been
146        moved to libcpu/powerpc/rtems/powerpc/powerpc.h.
147
1482008-07-10      Till Straumann <strauman@slac.stanford.edu>
149
150        * new-exceptions/bspsupport/README,
151        new-exceptions/bspsupport/ppc_exc.S,
152        new-exceptions/bspsupport/ppc_exc_asm_macros.h,
153        new-exceptions/bspsupport/ppc_exc_bspsupp.h,
154        new-exceptions/bspsupport/ppc_exc_hdl.c,
155        new-exceptions/bspsupport/vectors_init.c:
156        Fixed and enabled stack-switching algorithm which figures out
157        if we already run on the ISR stack rather than relying on the
158        _ISR_Nest_level.
159        Added 'ppc_exc_crit_always_enabled' variable which defines
160        the semantics of critical interrupts.
161        Let asynchronous machine-check handling never call the dispatcher.
162        We don't want to disable MSR_ME ever (to avoid checkstops)
163        and hence asynchronous MEs must not use OS services anyways.
164
1652008-07-09      Sebastian Huber <sebastian.huber@embedded-brains.de>
166
167        * shared/include/powerpc-utility.h: Includes standard header files,
168        provides common assembler macros and inline functions for low-level
169        code.
170
1712008-05-23      Thomas Doerfler <Thomas.Doerfler@embedded-brains.de>
172
173        * mpc83xx/network/tsec.c:
174        disabled debugging output, reduced rx interrupt coalescing
175
1762008-05-22      Till Straumann <strauman@slac.stanford.edu>
177
178        * ppc403/tty_drv/tty_drv.c, ppc403/console/console405.c:

1812008-05-16      Joel Sherrill <joel.sherrill@OARcorp.com>
182
183        * mpc83xx/include/mpc83xx.h: or is not a good name for any name in
184        C/C++. See iso646.h for the reason.
185
1862008-05-15      Thomas Doerfler <Thomas.Doerfler@embedded-brains.de>

200        added base frequency into softc structure
201
2022008-05-14      Till Straumann <strauman@slac.stanford.edu>
203
204        * new-exceptions/bspsupport/ppc_exc_bspsupp.h: added
205        comment about the semantics of the return value of
206        ppc_exc_handler_t.
207
2082008-05-14      Till Straumann <strauman@slac.stanford.edu>
209
210        * new-exceptions/bspsupport/irq.c: moved malloc/free
211        outside of irq-protected critical section.

226        mpc8260/console-generic/console-generic.c, mpc8260/include/console.h,
227        mpc8xx/console-generic/console-generic.c, mpc8xx/include/console.h:
228        Remove all references to console_reserve_resources and
229        termios_reserve_resources.
230
2312008-04-07      Thomas Doerfler <Thomas.Doerfler@embedded-brains.de>
232
233        * README:
234        removed reference to outdated "old-exception-handling" PPC support
235
2362008-03-20      Till Straumann <strauman@slac.stanford.edu>
237
238        * new-exceptions/bspsupport/irq.c: don't disable irqs
239        at the interrupt controller (PIC) during initialization -- this
240        caused problems where some BSPs's BSP_disable_irq_at_pic() routine
241        did not ignore IRQ lines associated with cascaded PICs.
242        Rely on the BSP (BSP_setup_the_pic()) to provide a good
243        initial setup.
244
2452008-03-13      Till Straumann <strauman@slac.stanford.edu>
246
247        * new-exceptions/bspsupport/ppc_exc_asm_macros.h,
248        new-exceptions/bspsupport/ppc_exc.S,
249        new-exceptions/bspsupport/README,
250        new-exceptions/bspsupport/ppc_exc_hdl.c:
251        Thomas Doerfler clarified (thanks!) that raising an
252        exception and executing the 1st instruction is not
253        an atomical operation. I added a fix to the code that
254        checks if a lower-priority interrupt is under way:
255        we now not only test if the 'lock' variable was set
256        but also check if the interrupted PC points to the
257        'write lock' instruction.
258        Added more comments and updated README.
259
2602008-03-11      Till Straumann <strauman@slac.stanford.edu>
261
262        * new-exceptions/bspsupport/ppc_exc_asm_macros.h: bugfix;
263        need to crand not cror when testing lower priority locks
264        during machine-check handling.
265
2662008-03-05      Till Straumann <strauman@slac.stanford.edu>
267

272
273        * old-exceptions/README, old-exceptions/TODO, old-exceptions/cpu.c,

294        TLB manipulation.
295
2962008-01-10      Till Straumann <strauman@slac.stanford.edu>
297
298        * new-exceptions/bspsupport/irq.c: When unhooking
299        and ISR only disable IRQs at the PIC if we are
300        unhooking the last ISR.
301
3022007-12-11      Till Straumann <strauman@slac.stanford.edu>
303
304        * Makefile.am: don't normally build-in test code

306
3072007-12-11      Till Straumann <strauman@slac.stanford.edu>
308
309        * Makefile.am, new-exceptions/bspsupport/README:
310        provide new irq_bspsupport.rel which was
311        split out of exc_bspsupport.rel to provide finer-grained
312        control over what BSPs want to use.
313
3142007-12-11      Till Straumann <strauman@slac.stanford.edu>
315
316        * new-exceptions/bspsupport/irq.c: enable/disable
317        irq at PIC if an initial handler is present/absent
318        (reproduce traditional semantics).
319
3202007-12-10      Till Straumann <strauman@slac.stanford.edu>
321
322        * new-exceptions/e500_raw_exc_init.c: map DEC
323        exception to ASM_BOOKE_DEC_VECTOR instead of ASM_DEC_VECTOR.
324
325        Fixed wrong mapping of ASM_BOOKE_FIT_VECTOR
326        (was ASM_BOOKE_PIT_VECTOR).
327
3282007-12-10      Till Straumann <strauman@slac.stanford.edu>
329
330        * new-exceptions/raw_exception.c, new_exceptions/raw_exception.h,
331        new_exceptions/bspsupport/irq.c: renamed ASM_BOOKE_PIT_VECTOR
332        to ASM_BOOKE_DEC_VECTOR to be closer to 'official'
333        nomenclature.
334
3352007-12-10      Till Straumann <strauman@slac.stanford.edu>
336
337        * new-exceptions/bspsupport/ppc_exc_test.c: fixed
338        wrong type in argument (signed vs. unsigned)
339        compiler warning.
340
3412007-12-10      Till Straumann <strauman@slac.stanford.edu>
342

350
3512007-12-10      Till Straumann <strauman@slac.stanford.edu>
352
353        * new-exceptions/bspsupport/ppc_exc_hdl.c: make sure
354        RI is set in the exception frame and panic if it isn't
355        (state info might have been lost). This only affects
356        classic PPC.
357
3582007-12-10      Till Straumann <strauman@slac.stanford.edu>

375
3762007-12-08      Till Straumann <strauman@slac.stanford.edu>

1775
1776        * old_exception_processing/cpu.h, shared/include/cpu.h: Renamed

1781
1782        * mpc6xx/timer/timer.c: Added include of bsp.h and removed external

1784        reference to this routine.
1785

1787
1788        * mpc8xx/console-generic/console-generic.c: Bug found by Yacine
1789        <elkolli@crf.canon.fr> where the initialization or irq data
1790        structure was incomplete in case a SMC channel was used first and
1791        later a SCC one.

17932001-05-17      Joel Sherrill <joel@OARcorp.com>
1794
1795        * mpc6xx/exceptions/raw_exception.c, pc6xx/mmu/pte121.c: Modified
1796        slightly to reflect recent PowerPC re-organization and avoid
1797        warnings.
1798
17992001-05-15      Till Straumann <strauman@slac.stanford.edu>
1800
1801        * mpc6xx/mmu/pte121.c, mpc6xx/mmu/pte121.h: New files. Missed in
1802        merge of PR213.
1803
18042001-05-14      Till Straumann <strauman@slac.stanford.edu>
1805
1806        * rtems/powerpc/registers.h, rtems/score/ppc.h: Per PR213, add  the
1807        following: - support for the MPC74000 (AKA G4); there is no AltiVec
1808        support yet, however. - the cache flushing assembly code uses
1809        hardware-flush on the G4. Also, a couple of hardcoded numerical
1810        values were replaced by more readable symbolic constants. - extended
1811        interrupt-disabled code section so enclose the entire cache
1812        flush/invalidate procedure (as recommended by the book). This is not
1813        (latency) critical as it is only used by init code but prevents
1814        possible corruption. - Trivial page table support as been added.
1815        (1:1 effective-virtual-physical address mapping which is only useful
1816        only on CPUs which feature hardware TLB replacement, e.g. >604.
1817        This allows for write-protecting memory regions, e.g. text/ro-data
1818        which makes catching corruptors a lot easier. It also frees one
1819        DBAT/IBAT and gives more flexibility for setting up address maps :
1820        -) - setdbat() allows changing BAT0 also (since the BSP may use a
1821        page table, BAT0 could be available...). - asm_setdbatX() violated
1822        the SVR ABI by using r20 as a scratch register; changed for r0 -
1823        according to the book, a context synchronizing instruction is
1824        necessary prior to and after changing a DBAT -> isync added
1825        * new-exceptions/cpu.c: Per PR211 fix saving/restoring floating
1826        point context.  The fpsave and fprestore routines are only used in a
1827        executing context which _is_ fp and hence has the FPU enabled. The
1828        current behavior required the FPU always to be on which is very
1829        dangerous if lazy context switching is used.   [Joel Note: Some
1830        ports explicitly enabled the FPU in the FP save and restore routines
1831        to avoid this.] The patch also makes sure (on powerpc only) that the
1832        FPU is disabled for integer tasks. Note that this is crucial if
1833        deferred fp context switching is used. Otherwise, fp context
1834        corruption may go undetected! Also note that even tasks which merely
1835        push/pop FP registers to/from the stack without modifying them still
1836        MUST be FP tasks - otherwise (if lazy FP context switching is used),
1837        FP register corruption (of other, FP, tasks may occur)! Furthermore,
1838        (on PPC) by default, lazy FP context save/restore is _disabled_.
1839        * shared/include/io.h: Per PR215 address the following issues: -
1840        _IO_BASE, _ISA_MEM_BASE and PCI_DRAM_OFFSET are no longer defined by
1841        libcpu (powerpc/shared/include/io.h) but by the BSP (who is the only
1842        one to know the values) - the affected BSP (shared/motorola) headers
1843        have been fixed in a separate "libbsp/powerpc/shared" patch. - the
1844        DEC 21140 driver (libchip/network/dec21140.c) has been fixed to use
1845        PCI_DRAM_OFFSET instead of PREP_PCI_DRAM_OFFSET. and PCI_MEM_BASE
1846        instead of PREP_ISA_MEM_BASE. PCI_MEM_BASE is to be defined by the
1847        BSP who is using this driver. - the DEC driver also has been fixed
1848        to use the newer rtems_bsp_delay_in_bus_cycles() instead of the
1849        obsolete delay_in_bus_cycles().

18592001-04-03      Joel Sherrill <joel@OARcorp.com>
1860
1861        * Closed PR57.  The hack is OK as it allows a BSP to override or not
1862        at its discretion.
1863        * Per PR94, all rtems/score/CPUtypes.h are named
1864        rtems/score/types.h.
1865        * Per PR94, all rtems/score/CPUtypes.h are named
1866        rtems/score/types.h.
1867        * mpc8xx/timer/timer.c: Removed #warning declaring providing a
1868        default definition for the macros
1869        rtems_cpu_configuration_get_timer_least_valid and
1870        rtems_cpu_configuration_get_timer_average_overhead.

1884        new_exception_processing/cpu.h, shared/include/byteorder.h,
1885        wrapup/Makefile.am: This is conversion of the mpc8xx CPU to the "new
1886        exception processing model."
1887        * mpc8xx/exceptions/Makefile.am,
1888        mpc8xx/exceptions/asm_utils.S, mpc8xx/exceptions/raw_exception.c,

1896        old_exception_processing/Makefile.am, pc403/ictrl/Makefile.am,
1897        shared/include/Makefile.am, shared/src/Makefile.am: Apply *_HEADERS
1898        instead of *H_FILES.
1899
19002001-01-03      Joel Sherrill <joel@OARcorp.com>
1901
1902        * new_exception_processing/cpu.h, old_exception_processing/cpu.c:
1903        old_exception_processing/cpu.h, Added _CPU_Initialize_vectors(). In
1904        particular, spurious vector initialization had to be moved on old
1905        exception processing model.
1906
19072000-11-09      Ralf Corsepius <corsepiu@faw.uni-ulm.de>
1908
1909        * Makefile.am: Use ... instead of RTEMS_TOPdir in ACLOCAL_AMFLAGS.
1910
19112000-11-02      Ralf Corsepius <corsepiu@faw.uni-ulm.de>
1912

1915
19162000-10-26      Ralf Corsepius <corsepiu@faw.uni-ulm.de>
1917
1918        * Makefile.am: ACLOCAL_AMFLAGS= -I $(RTEMS_TOPdir)/macros. Switch to
1919        GNU canonicalization.
1920
19212000-10-20      Joel Sherrill <joel@OARcorp.com>
1922
1923        * mpc8xx/console-generic/console-generic.c: Avoid use of BSP
1924        definitions and rely on the new routine
1925        mbx8xx_console_get_configuration() to get information.  This routine
1926        was formerly incorrectly called
1927        mbx8xx_console_use_maximum_buffer_size(). binding to the exception
1928        code.
1929        * configure.in, Makefile.am: Explicitly specify whether an
1930        RTEMS_CPU_MODEL is using old or new exception processing.  This is
1931        important because when building multilib, you do not know  the
1932        RTEMS_CPU_MODEL.  So everything built in a multilib'ed RTEMS must be
1933        independent of the exception model and allow for late binding to the
1934        exception code.
1935
19362000-10-18      Sergei Organov <osv@javad.ru>
1937

1940        addition.
1941        * old_exception_processing/Makefile.am: Account for ppc_offs.h.
1942        * old_exception_processing/cpu_asm.S: Offsets moved to ppc_offs.h.
1943        * mpc505/timer/timer.c: Use <rtems.h>, not "rtems.h".
1944        * mpc505/vectors/vectors.S: Now use constants for exception numbers.
1945        * mpc505/ictrl: New directory.
1946        * old_exception_processing/ppc_offs.h: New file.
1947        * old_exception_processing/cpu.h: Make Nest and Disable levels
1948        volatile.
1949        * mpc505/vectors/Makefile.am: alignment exception handler now
1950        included.
1951        * mpc505/ictrl/Makefile.am,
1952        mpc505/ictrl/ictrl.c, mpc505/ictrl/ictrl.h: New files.

19542000-10-18      Joel Sherrill <joel@OARcorp.com>
1955
1956        * mpc8xx/console-generic/console-generic.c: Removed include of
1957        <bsp.h> by adding BSP dependent routine
1958        mbx8xx_console_use_maximum_buffer_size() which can be hard coded or
1959        check non-volatile memory for configuration.
1960        * mpc8xx/console-generic/console-generic.c: Removed warnings.
1961        * mpc6xx/clock/c_clock.h: Removed commented out reference to
1962        <bsp.h>.
1963        * mpc6xx/timer/timer.c, mpc6xx/timer/timer.c: Ditto.
1964        * mpc6xx/clock/c_clock.c, mpc6xx/clock/c_clock.h: Removed use of
1965        bsp.h and replaced it with use of proper interfaces or explicit
1966        externs of required functions and data.
1967

19832000-08-11      Charles-Antoine Gauthier  <charles.gauthier@nrc.ca>
1984
1985        * mpc8xx/console-generic/console-generic.c: Add support for

1987
19882000-08-10      Charles-Antoine Gauthier  <charles.gauthier@nrc.ca>

1994
19952000-06-08      Eric Valette <valette@crf.canon.fr>
1996
1997        * mpc8xx/console-generic/console-generic.c: The printk/printf did
1998        not work when loaded by EPPCBUG. They did work when loaded with the
1999        BDM debugger.  I suspected EPPBUG  made some nasty things like
2000        patching Communication processor microcode...  Anyway, the attached
2001        patch: 1) Enables to have printk nearly immediately after boot, 2)
2002        Make printf work automagically (I do not know why except I make a
2003        different initialization for printk that should be overwritten by
2004        console init later ?) I let the default to be using EPPCBUG embedded
2005        firmware to boot and  using this printk early enabler code
2006        (LOADED_BY_EPPCBUG and  EARLY_CONSOLE) are on.
