7
8        * new-exceptions/cpu.c: use ppc_interrupt_get_disable_mask()

12
13        * new-exceptions/bspsupport/ppc_exc_asm_macros.h: Added
14        a test to TEST_LOCK_crit so that a context switch is
15        always prevented if MSR_CE is not set in the interrupt mask.
16        (Support mode where the user wants to leave MSR_CE always enabled
17        but abstains from calling OS primitives from the exception
18        handler.)

54
552008-07-14      Thomas Doerfler <thomas.doerfler@embedded-brains.de>
56
57        * Makefile.am, new-exceptions/raw_exception.c,
58        * new-exceptions/bspsupport/irq.c, ppc403/clock/clock_4xx.c,
59        * ppc403/include/ppc405ex.h, ppc403/include/ppc405gp.h,
60        * ppc403/timer/timer.c, rtems/powerpc/powerpc.h,
61        * shared/include/cpuIdent.c, shared/include/cpuIdent.h,
62        * shared/include/powerpc-utility.h:
63        Added support for PPC405EX (contributed by Michael Hamel)
64       
652008-07-11      Sebastian Huber <sebastian.huber@embedded-brains.de>
66
67        * Makefile.am: Install powerpc-utility.h.
68
69        * shared/include/cpuIdent.h, shared/include/cpuIdent.c: Added e200 and
70        e300 features.
71
72        * new-exceptions/cpu.c: Removed PR288 bugfix check.
73
74        * new-exceptions/e500_raw_exc_init.c: Added initialization for e200.
75        Set IVPR register for e200 and e500 to ppc_exc_vector_base.
76
77        * new-exceptions/raw_exception.c, new-exceptions/raw_exception.h: Added
78        vector categories for e200 and e300 cores.  Added global variable
79        ppc_exc_vector_base for CPUs with IVPR register.
80
81        * new-exceptions/bspsupport/ppc_exc.S,
82        * new-exceptions/bspsupport/ppc_exc_asm_macros.h,
83        * new-exceptions/bspsupport/ppc_exc_bspsupp.h,
84        * new-exceptions/bspsupport/ppc_exc_hdl.c,
85        * new-exceptions/bspsupport/vectors.h,
86        * new-exceptions/bspsupport/vectors_init.c:
87        Conistent code layout in most assember code sections and usage of
88        defines for registers.  Usage of standard header files to avoid
89        multiple definitions.
90       
91        Optimized exception code: Removed many branches and exploit branch
92        prediction for asynchronous exceptions, moved common wrap code into
93        WRAP macro to eliminate branch, static initialization of the handler
94        table with a default handler to eliminate the test if a handler is
95        present.  Register CR6 is no more cleared because the exeption handler
96        functions are not variadic.
97       
98        New method to switch to the interrupt stack. It will be tested if the
99        exception stack pointer is already inside the interrupt stack area.  It
100        is no more necessary to disable interrupts.  The SPRG1 and SPRG2 are
101        used to store the initial interrupt stack pointer and the interrupt
102        stack memory area start.
103
104        Removed variable ppc_exc_msr_irq_mask and use general interrupt disable
105        mask from SPRG0 instead.
106
107        New initialization routine ppc_exc_initialize() for bsp_start().  It
108        takes the interrupt disable mask, interrupt stack start and size as
109        parameters.
110
111        Added packed prologues for CPUs with IVPR and IVOR registers to save
112        memory space.
113
114        Reverted ppc_exc_crit_always_enabled change from yesterday.
115
116        WARNING: Tests with critical interrupt exceptions crash the system at
117        least on MPC8313ERDB and MPC8349EAMDS.  There may be somewhere a
118        serious bug with the new code.
119
1202008-07-10      Till Straumann <strauman@slac.stanford.edu>
121
122        * mpc6xx/mmu/pte121.c: use general "memory" clobber
123        rather than memory input operand in inline assembly
124        ("m" doesn't do what the manual says; see discussion
125        on gcc mailing list around 2008/3/30)
126
1272008-07-10      Till Straumann <strauman@slac.stanford.edu>
128
129        * ChangeLog, mpc8xx/clock/clock.c, ppc403/clock/clock.c,
130        ppc403/irq/ictrl.h, rtems/powerpc/powerpc.h:
131        Removed all macro definitions which depended on
132        the compiler defining a PPC CPU-model dependent
133        symbol from files in cpukit.
134        Macros which were not used by cpukit have been
135        moved to libcpu/powerpc/rtems/powerpc/powerpc.h.
136
1372008-07-10      Till Straumann <strauman@slac.stanford.edu>
138
139        * new-exceptions/bspsupport/README,
140        new-exceptions/bspsupport/ppc_exc.S,
141        new-exceptions/bspsupport/ppc_exc_asm_macros.h,
142        new-exceptions/bspsupport/ppc_exc_bspsupp.h,
143        new-exceptions/bspsupport/ppc_exc_hdl.c,
144        new-exceptions/bspsupport/vectors_init.c:
145        Fixed and enabled stack-switching algorithm which figures out
146        if we already run on the ISR stack rather than relying on the
147        _ISR_Nest_level.
148        Added 'ppc_exc_crit_always_enabled' variable which defines
149        the semantics of critical interrupts.
150        Let asynchronous machine-check handling never call the dispatcher.
151        We don't want to disable MSR_ME ever (to avoid checkstops)
152        and hence asynchronous MEs must not use OS services anyways.
153
1542008-07-09      Sebastian Huber <sebastian.huber@embedded-brains.de>
155
156        * shared/include/powerpc-utility.h: Includes standard header files,
157        provides common assembler macros and inline functions for low-level
158        code.
159
1602008-05-23      Thomas Doerfler <Thomas.Doerfler@embedded-brains.de>
161
162        * mpc83xx/network/tsec.c:
163        disabled debugging output, reduced rx interrupt coalescing
164

1702008-05-16      Joel Sherrill <joel.sherrill@OARcorp.com>
171
172        * mpc83xx/include/mpc83xx.h: or is not a good name for any name in
173        C/C++. See iso646.h for the reason.
174
1752008-05-15      Thomas Doerfler <Thomas.Doerfler@embedded-brains.de>

190
1912008-05-14      Till Straumann <strauman@slac.stanford.edu>
192
193        * new-exceptions/bspsupport/ppc_exc_bspsupp.h: added
194        comment about the semantics of the return value of
195        ppc_exc_handler_t.
196
1972008-05-14      Till Straumann <strauman@slac.stanford.edu>
198
199        * new-exceptions/bspsupport/irq.c: moved malloc/free
200        outside of irq-protected critical section.

206        console_reserve_resources and termios_reserve_resources.
207
2082008-04-24      Nigel Spon <nigel@adi.co.nz>
209
210        * ppc403/console/console.c: Correct include path.
211
2122008-04-23      Joel Sherrill <joel.sherrill@OARcorp.com>
213
214        * mpc5xx/console-generic/console-generic.c, mpc5xx/include/console.h,
215        mpc8260/console-generic/console-generic.c, mpc8260/include/console.h,
216        mpc8xx/console-generic/console-generic.c, mpc8xx/include/console.h:
217        Remove all references to console_reserve_resources and
218        termios_reserve_resources.
219
2202008-04-07      Thomas Doerfler <Thomas.Doerfler@embedded-brains.de>
221
222        * README:
223        removed reference to outdated "old-exception-handling" PPC support
224
2252008-03-20      Till Straumann <strauman@slac.stanford.edu>
226
227        * new-exceptions/bspsupport/irq.c: don't disable irqs
228        at the interrupt controller (PIC) during initialization -- this
229        caused problems where some BSPs's BSP_disable_irq_at_pic() routine
230        did not ignore IRQ lines associated with cascaded PICs.
231        Rely on the BSP (BSP_setup_the_pic()) to provide a good
232        initial setup.
233
2342008-03-13      Till Straumann <strauman@slac.stanford.edu>
235
236        * new-exceptions/bspsupport/ppc_exc_asm_macros.h,

238        new-exceptions/bspsupport/README,
239        new-exceptions/bspsupport/ppc_exc_hdl.c:
240        Thomas Doerfler clarified (thanks!) that raising an
241        exception and executing the 1st instruction is not
242        an atomical operation. I added a fix to the code that
243        checks if a lower-priority interrupt is under way:
244        we now not only test if the 'lock' variable was set
245        but also check if the interrupted PC points to the
246        'write lock' instruction.
247        Added more comments and updated README.
248
2492008-03-11      Till Straumann <strauman@slac.stanford.edu>
250
251        * new-exceptions/bspsupport/ppc_exc_asm_macros.h: bugfix;
252        need to crand not cror when testing lower priority locks
253        during machine-check handling.
254
2552008-03-05      Till Straumann <strauman@slac.stanford.edu>
256
257        * new-exceptions/bspsupport/ppc_exc_asm_macros.h: bugfix;
258        need to andc with irq mask when disabling interrupts.
259
2602008-02-19      Ralf Corsépius <ralf.corsepius@rtems.org>
261
262        * old-exceptions/README, old-exceptions/TODO, old-exceptions/cpu.c,

268        Eliminate OLD_EXCEPTIONS.
269        * configure.ac: Remove OLD_EXCEPTIONS.
270

272
273        * configure.ac: Deactivate old-exceptions.
274
2752008-02-15      Joel Sherrill <joel.sherrill@OARcorp.com>

283        TLB manipulation.
284
2852008-01-10      Till Straumann <strauman@slac.stanford.edu>
286
287        * new-exceptions/bspsupport/irq.c: When unhooking
288        and ISR only disable IRQs at the PIC if we are
289        unhooking the last ISR.
290
2912007-12-11      Till Straumann <strauman@slac.stanford.edu>
292
293        * Makefile.am: don't normally build-in test code

295
2962007-12-11      Till Straumann <strauman@slac.stanford.edu>
297
298        * Makefile.am, new-exceptions/bspsupport/README:
299        provide new irq_bspsupport.rel which was
300        split out of exc_bspsupport.rel to provide finer-grained
301        control over what BSPs want to use.
302
3032007-12-11      Till Straumann <strauman@slac.stanford.edu>
304
305        * new-exceptions/bspsupport/irq.c: enable/disable
306        irq at PIC if an initial handler is present/absent
307        (reproduce traditional semantics).
308
3092007-12-10      Till Straumann <strauman@slac.stanford.edu>
310
311        * new-exceptions/e500_raw_exc_init.c: map DEC
312        exception to ASM_BOOKE_DEC_VECTOR instead of ASM_DEC_VECTOR.
313
314        Fixed wrong mapping of ASM_BOOKE_FIT_VECTOR
315        (was ASM_BOOKE_PIT_VECTOR).
316
3172007-12-10      Till Straumann <strauman@slac.stanford.edu>
318
319        * new-exceptions/raw_exception.c, new_exceptions/raw_exception.h,
320        new_exceptions/bspsupport/irq.c: renamed ASM_BOOKE_PIT_VECTOR
321        to ASM_BOOKE_DEC_VECTOR to be closer to 'official'
322        nomenclature.
323
3242007-12-10      Till Straumann <strauman@slac.stanford.edu>
325
326        * new-exceptions/bspsupport/ppc_exc_test.c: fixed
327        wrong type in argument (signed vs. unsigned)
328        compiler warning.
329
3302007-12-10      Till Straumann <strauman@slac.stanford.edu>
331
332        * Makefile.am: build new-exceptions/bspsupport for

339
3402007-12-10      Till Straumann <strauman@slac.stanford.edu>
341
342        * new-exceptions/bspsupport/ppc_exc_hdl.c: make sure
343        RI is set in the exception frame and panic if it isn't
344        (state info might have been lost). This only affects
345        classic PPC.
346
3472007-12-10      Till Straumann <strauman@slac.stanford.edu>
348
349        * new-exceptions/bspsupport/README,

363        in ppc_exc_test.c so that it works on PSIM.
364
3652007-12-08      Till Straumann <strauman@slac.stanford.edu>
366
367        * irq_supp.h: was moved from libbsp/powerpc/shared/irq to

369
3702007-12-08      Till Straumann <strauman@slac.stanford.edu>

386        new-exceptions/bspsupport/ppc_exc_asm_macros.h,
387        new-exceptions/bspsupport/nested_irq_test.c:
388        New files. Added 'middleware' code for helping BSPs implement
389        exception and interrupt handling and implementing the 'new'
390        RTEMS IRQ API (which I personally dislike).

1764
1765        * old_exception_processing/cpu.h, shared/include/cpu.h: Renamed
1766        delay() to rtems_bsp_delay(). Renamed delay_in_bus_cycles() to
1767        rtems_bsp_delay_in_bus_cycles().

1770
1771        * mpc6xx/timer/timer.c: Added include of bsp.h and removed external
1772        declaration of BSP_Convert_decrementer() to  correct unresolved
1773        reference to this routine.
1774

1776
1777        * mpc8xx/console-generic/console-generic.c: Bug found by Yacine
1778        <elkolli@crf.canon.fr> where the initialization or irq data
1779        structure was incomplete in case a SMC channel was used first and
1780        later a SCC one.

17822001-05-17      Joel Sherrill <joel@OARcorp.com>
1783
1784        * mpc6xx/exceptions/raw_exception.c, pc6xx/mmu/pte121.c: Modified
1785        slightly to reflect recent PowerPC re-organization and avoid
1786        warnings.
1787
17882001-05-15      Till Straumann <strauman@slac.stanford.edu>
1789
1790        * mpc6xx/mmu/pte121.c, mpc6xx/mmu/pte121.h: New files. Missed in
1791        merge of PR213.
1792
17932001-05-14      Till Straumann <strauman@slac.stanford.edu>
1794
1795        * rtems/powerpc/registers.h, rtems/score/ppc.h: Per PR213, add  the
1796        following: - support for the MPC74000 (AKA G4); there is no AltiVec
1797        support yet, however. - the cache flushing assembly code uses
1798        hardware-flush on the G4. Also, a couple of hardcoded numerical
1799        values were replaced by more readable symbolic constants. - extended
1800        interrupt-disabled code section so enclose the entire cache
1801        flush/invalidate procedure (as recommended by the book). This is not
1802        (latency) critical as it is only used by init code but prevents
1803        possible corruption. - Trivial page table support as been added.
1804        (1:1 effective-virtual-physical address mapping which is only useful
1805        only on CPUs which feature hardware TLB replacement, e.g. >604.
1806        This allows for write-protecting memory regions, e.g. text/ro-data
1807        which makes catching corruptors a lot easier. It also frees one
1808        DBAT/IBAT and gives more flexibility for setting up address maps :
1809        -) - setdbat() allows changing BAT0 also (since the BSP may use a
1810        page table, BAT0 could be available...). - asm_setdbatX() violated
1811        the SVR ABI by using r20 as a scratch register; changed for r0 -
1812        according to the book, a context synchronizing instruction is
1813        necessary prior to and after changing a DBAT -> isync added
1814        * new-exceptions/cpu.c: Per PR211 fix saving/restoring floating
1815        point context.  The fpsave and fprestore routines are only used in a
1816        executing context which _is_ fp and hence has the FPU enabled. The
1817        current behavior required the FPU always to be on which is very
1818        dangerous if lazy context switching is used.   [Joel Note: Some
1819        ports explicitly enabled the FPU in the FP save and restore routines
1820        to avoid this.] The patch also makes sure (on powerpc only) that the
1821        FPU is disabled for integer tasks. Note that this is crucial if
1822        deferred fp context switching is used. Otherwise, fp context
1823        corruption may go undetected! Also note that even tasks which merely
1824        push/pop FP registers to/from the stack without modifying them still
1825        MUST be FP tasks - otherwise (if lazy FP context switching is used),
1826        FP register corruption (of other, FP, tasks may occur)! Furthermore,
1827        (on PPC) by default, lazy FP context save/restore is _disabled_.
1828        * shared/include/io.h: Per PR215 address the following issues: -
1829        _IO_BASE, _ISA_MEM_BASE and PCI_DRAM_OFFSET are no longer defined by
1830        libcpu (powerpc/shared/include/io.h) but by the BSP (who is the only
1831        one to know the values) - the affected BSP (shared/motorola) headers
1832        have been fixed in a separate "libbsp/powerpc/shared" patch. - the
1833        DEC 21140 driver (libchip/network/dec21140.c) has been fixed to use
1834        PCI_DRAM_OFFSET instead of PREP_PCI_DRAM_OFFSET. and PCI_MEM_BASE
1835        instead of PREP_ISA_MEM_BASE. PCI_MEM_BASE is to be defined by the
1836        BSP who is using this driver. - the DEC driver also has been fixed
1837        to use the newer rtems_bsp_delay_in_bus_cycles() instead of the
1838        obsolete delay_in_bus_cycles().

1841
1842        * shared/include/cpuIdent.c: Account for duplicate numbers.

18442001-04-17      Joel Sherrill <joel@OARcorp.com>
1845
1846        * shared/include/cpu.h: Added ifndef ASM.
1847
18482001-04-03      Joel Sherrill <joel@OARcorp.com>
1849
1850        * Closed PR57.  The hack is OK as it allows a BSP to override or not
1851        at its discretion.
1852        * Per PR94, all rtems/score/CPUtypes.h are named
1853        rtems/score/types.h.
1854        * Per PR94, all rtems/score/CPUtypes.h are named
1855        rtems/score/types.h.
1856        * mpc8xx/timer/timer.c: Removed #warning declaring providing a
1857        default definition for the macros
1858        rtems_cpu_configuration_get_timer_least_valid and
1859        rtems_cpu_configuration_get_timer_average_overhead.
1860        * old-exceptions/rtems/score/cpu.h,
1861        new-exceptions/rtems/score/cpu.h: Account for name change.

1865        * mpc8xx/vectors/Makefile.am,
1866        mpc8xx/vectors/README, mpc8xx/vectors/align_h.S
1867        mpc8xx/vectors/vectors.S: These files were removed in support of
1868        switching the mpc8xx to the use the "new exception processing
1869        model."
1870        * configure.in, mpc6xx/mmu/bat.h, mpc8xx/Makefile.am,
1871        mpc8xx/clock/clock.c, mpc8xx/console-generic/console-generic.c,
1872        mpc8xx/include/mpc8xx.h, mpc8xx/mmu/mmu.c,
1873        new_exception_processing/cpu.h, shared/include/byteorder.h,
1874        wrapup/Makefile.am: This is conversion of the mpc8xx CPU to the "new
1875        exception processing model."
1876        * mpc8xx/exceptions/Makefile.am,
1877        mpc8xx/exceptions/asm_utils.S, mpc8xx/exceptions/raw_exception.c,
1878        mpc8xx/exceptions/raw_exception.h: New files.
1879
18802001-02-27      Ralf Corsepius <corsepiu@faw.uni-ulm.de>
1881
1882        * mpc505/ictrl/Makefile.am, mpc6xx/clock/Makefile.am,
1883        mpc6xx/exceptions/Makefile.am, mpc6xx/mmu/Makefile.am,
1884        mpc8xx/include/Makefile.am, new_exception_processing/Makefile.am,
1885        old_exception_processing/Makefile.am, pc403/ictrl/Makefile.am,
1886        shared/include/Makefile.am, shared/src/Makefile.am: Apply *_HEADERS
1887        instead of *H_FILES.
1888
18892001-01-03      Joel Sherrill <joel@OARcorp.com>
1890
1891        * new_exception_processing/cpu.h, old_exception_processing/cpu.c:
1892        old_exception_processing/cpu.h, Added _CPU_Initialize_vectors(). In
1893        particular, spurious vector initialization had to be moved on old
1894        exception processing model.
1895
18962000-11-09      Ralf Corsepius <corsepiu@faw.uni-ulm.de>
1897
1898        * Makefile.am: Use ... instead of RTEMS_TOPdir in ACLOCAL_AMFLAGS.
1899
19002000-11-02      Ralf Corsepius <corsepiu@faw.uni-ulm.de>
1901
1902        * Makefile.am: Switch to ACLOCAL_AMFLAGS = -I
1903        $(RTEMS_TOPdir)/aclocal.
1904
19052000-10-26      Ralf Corsepius <corsepiu@faw.uni-ulm.de>
1906
1907        * Makefile.am: ACLOCAL_AMFLAGS= -I $(RTEMS_TOPdir)/macros. Switch to
1908        GNU canonicalization.
1909
19102000-10-20      Joel Sherrill <joel@OARcorp.com>
1911
1912        * mpc8xx/console-generic/console-generic.c: Avoid use of BSP
1913        definitions and rely on the new routine
1914        mbx8xx_console_get_configuration() to get information.  This routine
1915        was formerly incorrectly called
1916        mbx8xx_console_use_maximum_buffer_size(). binding to the exception
1917        code.
1918        * configure.in, Makefile.am: Explicitly specify whether an
1919        RTEMS_CPU_MODEL is using old or new exception processing.  This is
1920        important because when building multilib, you do not know  the
1921        RTEMS_CPU_MODEL.  So everything built in a multilib'ed RTEMS must be
1922        independent of the exception model and allow for late binding to the
1923        exception code.
1924
19252000-10-18      Sergei Organov <osv@javad.ru>
1926
1927        * Added full support for MPC505.
1928        * configure.in, mpc505/Makefile.am: Modified to reflect ictrl
1929        addition.
1930        * old_exception_processing/Makefile.am: Account for ppc_offs.h.
1931        * old_exception_processing/cpu_asm.S: Offsets moved to ppc_offs.h.
1932        * mpc505/timer/timer.c: Use <rtems.h>, not "rtems.h".
1933        * mpc505/vectors/vectors.S: Now use constants for exception numbers.
1934        * mpc505/ictrl: New directory.
1935        * old_exception_processing/ppc_offs.h: New file.
1936        * old_exception_processing/cpu.h: Make Nest and Disable levels
1937        volatile.
1938        * mpc505/vectors/Makefile.am: alignment exception handler now
1939        included.
1940        * mpc505/ictrl/Makefile.am,
1941        mpc505/ictrl/ictrl.c, mpc505/ictrl/ictrl.h: New files.

19432000-10-18      Joel Sherrill <joel@OARcorp.com>
1944
1945        * mpc8xx/console-generic/console-generic.c: Removed include of
1946        <bsp.h> by adding BSP dependent routine
1947        mbx8xx_console_use_maximum_buffer_size() which can be hard coded or
1948        check non-volatile memory for configuration.
1949        * mpc8xx/console-generic/console-generic.c: Removed warnings.
1950        * mpc6xx/clock/c_clock.h: Removed commented out reference to
1951        <bsp.h>.
1952        * mpc6xx/timer/timer.c, mpc6xx/timer/timer.c: Ditto.
1953        * mpc6xx/clock/c_clock.c, mpc6xx/clock/c_clock.h: Removed use of
1954        bsp.h and replaced it with use of proper interfaces or explicit
1955        externs of required functions and data.
1956
19572000-09-04      Ralf Corsepius <corsepiu@faw.uni-ulm.de>

1971
19722000-08-11      Charles-Antoine Gauthier  <charles.gauthier@nrc.ca>
1973
1974        * mpc8xx/console-generic/console-generic.c: Add support for
1975        configuration parameters in NVRAM
1976
19772000-08-10      Charles-Antoine Gauthier  <charles.gauthier@nrc.ca>
1978
1979        * mpx8xx/console-generic/console-generic.c(m8xx_uart_pollWrite):
1980        Flush actual buffer.
1981        * mpx8xx/console-generic/console-generic.c: Addition of support for
1982        shared printk and no termios.
1983
19842000-06-08      Eric Valette <valette@crf.canon.fr>
1985
1986        * mpc8xx/console-generic/console-generic.c: The printk/printf did
1987        not work when loaded by EPPCBUG. They did work when loaded with the
1988        BDM debugger.  I suspected EPPBUG  made some nasty things like
1989        patching Communication processor microcode...  Anyway, the attached
1990        patch: 1) Enables to have printk nearly immediately after boot, 2)
1991        Make printf work automagically (I do not know why except I make a
1992        different initialization for printk that should be overwritten by
1993        console init later ?) I let the default to be using EPPCBUG embedded
1994        firmware to boot and  using this printk early enabler code
1995        (LOADED_BY_EPPCBUG and  EARLY_CONSOLE) are on.
