33        The Shared Memory Driver no longer requires the special IOCTL in
34        Clock_control. This was a hack which has existed since before the
35        Classic API Timer Manager was implemented. All implementations of and
36        references to Clock_control were removed.

104
105        * ppc403/clock/clock.c: Added (conditionally compiled)
106        code so that a BSP can choose to hook the timer exception
107        directly rather than going through the interrupt dispatcher.
108
1092008-07-21      Till Straumann <strauman@slac.stanford.edu>
110
111        * new-exceptions/raw_exception,h,

114       
1152008-07-18      Sebastian Huber <sebastian.huber@embedded-brains.de>
116
117        * shared/include/powerpc-utility.h: Changed special purpose register
118        inline functions to macros.  Added macros to set and clear bits for
119        SPRs and DCRs.
120
121        * new-exceptions/raw_exception.c: The watchdog exception for e200 is
122        now asynchronous.

125
126        * mpc55xx/include/watchdog.h: New file.

129
1302008-07-18      Thomas Doerfler <thomas.doerfler@embedded-brains.de>
131
132        * mpc83xx/network/tsec.c: Initialize PHY registers late enough,

134
1352008-07-17      Thomas Doerfler <thomas.doerfler@embedded-brains.de>
136
137        * rtems/powerpc/powerpc.h:
138        ppc405 uses definitions distinct from ppc403 now
139        * shared/src/cache_.h: Use correct powerpc.h to get cache attributes
140
141       
1422008-07-17      Thomas Doerfler <thomas.doerfler@embedded-brains.de>
143
144        * shared/include/powerpc-utility.h:
145        Fixed typo in access macros for device control registers (DCR)
146       
1472008-07-16      Till Straumann <strauman@slac.stanford.edu>
148
149        * new-exceptions/bspsupport/vectors_init.c: added
150        features to C_exception_handler() (the default global
151        handler):
152         - try to catch recursion
153         - print info about context where the exception occurred
154           (ISR or task with task ID).
155         - suspend offending task rather than spinning forever.
156       
1572008-07-16      Till Straumann <strauman@slac.stanford.edu>
158
159        * new-exceptions/bspsupport/vectors_init.c: must not
160        align start of stack downwards (we don't 'own' memory
161        below start). Instead, use original boundaries but
162        align the stack pointer as required.
163
164        Added test to verify that R13 was loaded with _SDA_BASE_
165        during early initialization (low-level assembly code
166        relies on it).
167
1682008-07-16      Till Straumann <strauman@slac.stanford.edu>
169
170        * new-exceptions/cpu.c: propagate R2 to all task contexts
171        even if the ABI is SVR4. Cannot hurt...
172
1732008-07-16      Till Straumann <strauman@slac.stanford.edu>
174
175        * new-exceptions/cpu.c: use ppc_interrupt_get_disable_mask()
176        to determine which bits to set/clear from _CPU_Context_Initialize().
177
1782008-07-16      Till Straumann <strauman@slac.stanford.edu>
179
180        * new-exceptions/bspsupport/ppc_exc_asm_macros.h: Added
181        a test to TEST_LOCK_crit so that a context switch is
182        always prevented if MSR_CE is not set in the interrupt mask.
183        (Support mode where the user wants to leave MSR_CE always enabled
184        but abstains from calling OS primitives from the exception
185        handler.)
186
1872008-07-16      Till Straumann <strauman@slac.stanford.edu>
188
189        * shared/include/powerpc-utility.h: Added
190        GET_INTERRUPT_MASK macro.

212        * shared/include/powerpc-utility.h: Exchanged ASM and non ASM code
213        sections.
214
215        * rtems/powerpc/powerpc.h, shared/src/cache.c, shared/src/cache_.h:
216        New defines PPC_NO_CACHE_ALIGNMENT and PPC_NO_CACHE_ALIGNMENT_POWER for
217        CPUs with no cache.  Provide default implementations for all cache
218        functions.
219
220        * mpc83xx/include/gtm.h, mpc83xx/gtm/gtm.c: New files.
221
2222008-07-14      Thomas Doerfler <thomas.doerfler@embedded-brains.de>

228        * shared/include/cpuIdent.c, shared/include/cpuIdent.h,
229        * shared/include/powerpc-utility.h:
230        Added support for PPC405EX (contributed by Michael Hamel)
231       
2322008-07-11      Sebastian Huber <sebastian.huber@embedded-brains.de>
233
234        * Makefile.am: Install powerpc-utility.h.
235
236        * shared/include/cpuIdent.h, shared/include/cpuIdent.c: Added e200 and
237        e300 features.
238
239        * new-exceptions/cpu.c: Removed PR288 bugfix check.
240
241        * new-exceptions/e500_raw_exc_init.c: Added initialization for e200.
242        Set IVPR register for e200 and e500 to ppc_exc_vector_base.
243
244        * new-exceptions/raw_exception.c, new-exceptions/raw_exception.h: Added
245        vector categories for e200 and e300 cores.  Added global variable
246        ppc_exc_vector_base for CPUs with IVPR register.
247
248        * new-exceptions/bspsupport/ppc_exc.S,
249        * new-exceptions/bspsupport/ppc_exc_asm_macros.h,
250        * new-exceptions/bspsupport/ppc_exc_bspsupp.h,
251        * new-exceptions/bspsupport/ppc_exc_hdl.c,
252        * new-exceptions/bspsupport/vectors.h,
253        * new-exceptions/bspsupport/vectors_init.c:
254        Conistent code layout in most assember code sections and usage of
255        defines for registers.  Usage of standard header files to avoid
256        multiple definitions.
257       
258        Optimized exception code: Removed many branches and exploit branch
259        prediction for asynchronous exceptions, moved common wrap code into
260        WRAP macro to eliminate branch, static initialization of the handler
261        table with a default handler to eliminate the test if a handler is
262        present.  Register CR6 is no more cleared because the exeption handler
263        functions are not variadic.
264       
265        New method to switch to the interrupt stack. It will be tested if the
266        exception stack pointer is already inside the interrupt stack area.  It
267        is no more necessary to disable interrupts.  The SPRG1 and SPRG2 are
268        used to store the initial interrupt stack pointer and the interrupt
269        stack memory area start.
270
271        Removed variable ppc_exc_msr_irq_mask and use general interrupt disable
272        mask from SPRG0 instead.
273
274        New initialization routine ppc_exc_initialize() for bsp_start().  It
275        takes the interrupt disable mask, interrupt stack start and size as
276        parameters.
277
278        Added packed prologues for CPUs with IVPR and IVOR registers to save
279        memory space.
280
281        Reverted ppc_exc_crit_always_enabled change from yesterday.
282
283        WARNING: Tests with critical interrupt exceptions crash the system at
284        least on MPC8313ERDB and MPC8349EAMDS.  There may be somewhere a
285        serious bug with the new code.
286
2872008-07-10      Till Straumann <strauman@slac.stanford.edu>
288
289        * mpc6xx/mmu/pte121.c: use general "memory" clobber
290        rather than memory input operand in inline assembly
291        ("m" doesn't do what the manual says; see discussion
292        on gcc mailing list around 2008/3/30)
293
2942008-07-10      Till Straumann <strauman@slac.stanford.edu>
295
296        * ChangeLog, mpc8xx/clock/clock.c, ppc403/clock/clock.c,
297        ppc403/irq/ictrl.h, rtems/powerpc/powerpc.h:
298        Removed all macro definitions which depended on
299        the compiler defining a PPC CPU-model dependent
300        symbol from files in cpukit.
301        Macros which were not used by cpukit have been
302        moved to libcpu/powerpc/rtems/powerpc/powerpc.h.
303
3042008-07-10      Till Straumann <strauman@slac.stanford.edu>
305
306        * new-exceptions/bspsupport/README,
307        new-exceptions/bspsupport/ppc_exc.S,
308        new-exceptions/bspsupport/ppc_exc_asm_macros.h,
309        new-exceptions/bspsupport/ppc_exc_bspsupp.h,
310        new-exceptions/bspsupport/ppc_exc_hdl.c,
311        new-exceptions/bspsupport/vectors_init.c:
312        Fixed and enabled stack-switching algorithm which figures out
313        if we already run on the ISR stack rather than relying on the
314        _ISR_Nest_level.
315        Added 'ppc_exc_crit_always_enabled' variable which defines
316        the semantics of critical interrupts.
317        Let asynchronous machine-check handling never call the dispatcher.
318        We don't want to disable MSR_ME ever (to avoid checkstops)
319        and hence asynchronous MEs must not use OS services anyways.
320
3212008-07-09      Sebastian Huber <sebastian.huber@embedded-brains.de>
322
323        * shared/include/powerpc-utility.h: Includes standard header files,

333
334        * ppc403/tty_drv/tty_drv.c, ppc403/console/console405.c:
335        ../ictrl/ictrl.h has gone; include ../irq/ictrl.h
336
3372008-05-16      Joel Sherrill <joel.sherrill@OARcorp.com>
338
339        * mpc83xx/include/mpc83xx.h: or is not a good name for any name in

341
3422008-05-15      Thomas Doerfler <Thomas.Doerfler@embedded-brains.de>

357
3582008-05-14      Till Straumann <strauman@slac.stanford.edu>
359
360        * new-exceptions/bspsupport/ppc_exc_bspsupp.h: added
361        comment about the semantics of the return value of
362        ppc_exc_handler_t.
363
3642008-05-14      Till Straumann <strauman@slac.stanford.edu>
365
366        * new-exceptions/bspsupport/irq.c: moved malloc/free
367        outside of irq-protected critical section.
368
3692008-04-24      Joel Sherrill <joel.sherrill@OARcorp.com>

394        * new-exceptions/bspsupport/irq.c: don't disable irqs
395        at the interrupt controller (PIC) during initialization -- this
396        caused problems where some BSPs's BSP_disable_irq_at_pic() routine
397        did not ignore IRQ lines associated with cascaded PICs.

407        Thomas Doerfler clarified (thanks!) that raising an
408        exception and executing the 1st instruction is not
409        an atomical operation. I added a fix to the code that
410        checks if a lower-priority interrupt is under way:
411        we now not only test if the 'lock' variable was set
412        but also check if the interrupted PC points to the
413        'write lock' instruction.

776        should use the public API for

778        public API and directly accessing _CPU_ISR_Disable and
779        _CPU_ISR_Enable, they were bypassing the compiler memory barrier
780        directive which could lead to problems. This patch also changes the

782        style issues.

1839
1840        * new_exception_processing/cpu_asm.S: Support double or single
1841        precision context switches.  Note that doing a single precision
1842        context save/restore on a double precision PowerPC machine does not
1843        only result in rounding errors but also screws up the FPSCR

1848        This modification is part of the submitted modifications necessary
1849        to
1850        support the IBM PPC405 family.  This submission was reviewed by
1851        Thomas Doerfler <Thomas.Doerfler@imd-systems.de> who ensured it did
1852        not negatively impact the ppc403 BSPs.  The submission and tracking
1853        process was captured as PR50.

18632001-11-07      Joel Sherrill <joel@OARcorp.com>
1864
1865        * configure.ac: Delete the commented out line that said that the
1866        mpc8260 used the old exception processing model.  This line also
1867        appears to have caused ppc603e to miss this test.

18692001-10-29      Joel Sherrill <joel@OARcorp.com>
1870
1871        * mpc8xx/timer/timer.c: Added hack for two macros that are not

1937
1938        * mpc6xx/timer/timer.c: Added include of bsp.h and removed external
1939        declaration of BSP_Convert_decrementer() to  correct unresolved
1940        reference to this routine.
1941
19422001-05-24      Eric Valette <valette@crf.canon.fr>
1943
1944        * mpc8xx/console-generic/console-generic.c: Bug found by Yacine
1945        <elkolli@crf.canon.fr> where the initialization or irq data
1946        structure was incomplete in case a SMC channel was used first and
1947        later a SCC one.
1948
19492001-05-17      Joel Sherrill <joel@OARcorp.com>
1950
1951        * mpc6xx/exceptions/raw_exception.c, pc6xx/mmu/pte121.c: Modified
1952        slightly to reflect recent PowerPC re-organization and avoid
1953        warnings.
1954
19552001-05-15      Till Straumann <strauman@slac.stanford.edu>
1956
1957        * mpc6xx/mmu/pte121.c, mpc6xx/mmu/pte121.h: New files. Missed in
1958        merge of PR213.
1959
19602001-05-14      Till Straumann <strauman@slac.stanford.edu>
1961
1962        * rtems/powerpc/registers.h, rtems/score/ppc.h: Per PR213, add  the
1963        following: - support for the MPC74000 (AKA G4); there is no AltiVec
1964        support yet, however. - the cache flushing assembly code uses
1965        hardware-flush on the G4. Also, a couple of hardcoded numerical
1966        values were replaced by more readable symbolic constants. - extended
1967        interrupt-disabled code section so enclose the entire cache
1968        flush/invalidate procedure (as recommended by the book). This is not
1969        (latency) critical as it is only used by init code but prevents
1970        possible corruption. - Trivial page table support as been added.
1971        (1:1 effective-virtual-physical address mapping which is only useful
1972        only on CPUs which feature hardware TLB replacement, e.g. >604.
1973        This allows for write-protecting memory regions, e.g. text/ro-data
1974        which makes catching corruptors a lot easier. It also frees one
1975        DBAT/IBAT and gives more flexibility for setting up address maps :
1976        -) - setdbat() allows changing BAT0 also (since the BSP may use a
1977        page table, BAT0 could be available...). - asm_setdbatX() violated
1978        the SVR ABI by using r20 as a scratch register; changed for r0 -
1979        according to the book, a context synchronizing instruction is
1980        necessary prior to and after changing a DBAT -> isync added
1981        * new-exceptions/cpu.c: Per PR211 fix saving/restoring floating
1982        point context.  The fpsave and fprestore routines are only used in a
1983        executing context which _is_ fp and hence has the FPU enabled. The
1984        current behavior required the FPU always to be on which is very
1985        dangerous if lazy context switching is used.   [Joel Note: Some
1986        ports explicitly enabled the FPU in the FP save and restore routines
1987        to avoid this.] The patch also makes sure (on powerpc only) that the
1988        FPU is disabled for integer tasks. Note that this is crucial if
1989        deferred fp context switching is used. Otherwise, fp context
1990        corruption may go undetected! Also note that even tasks which merely
1991        push/pop FP registers to/from the stack without modifying them still
1992        MUST be FP tasks - otherwise (if lazy FP context switching is used),
1993        FP register corruption (of other, FP, tasks may occur)! Furthermore,
1994        (on PPC) by default, lazy FP context save/restore is _disabled_.
1995        * shared/include/io.h: Per PR215 address the following issues: -
1996        _IO_BASE, _ISA_MEM_BASE and PCI_DRAM_OFFSET are no longer defined by
1997        libcpu (powerpc/shared/include/io.h) but by the BSP (who is the only
1998        one to know the values) - the affected BSP (shared/motorola) headers
1999        have been fixed in a separate "libbsp/powerpc/shared" patch. - the
2000        DEC 21140 driver (libchip/network/dec21140.c) has been fixed to use
2001        PCI_DRAM_OFFSET instead of PREP_PCI_DRAM_OFFSET. and PCI_MEM_BASE
2002        instead of PREP_ISA_MEM_BASE. PCI_MEM_BASE is to be defined by the
2003        BSP who is using this driver. - the DEC driver also has been fixed
2004        to use the newer rtems_bsp_delay_in_bus_cycles() instead of the
2005        obsolete delay_in_bus_cycles().
2006
20072001-05-14      Joel Sherrill <joel@OARcorp.com>
2008
2009        * shared/include/cpuIdent.c: Account for duplicate numbers.
2010
20112001-04-17      Joel Sherrill <joel@OARcorp.com>
2012
2013        * shared/include/cpu.h: Added ifndef ASM.
2014
20152001-04-03      Joel Sherrill <joel@OARcorp.com>
2016
2017        * Closed PR57.  The hack is OK as it allows a BSP to override or not
2018        at its discretion.
2019        * Per PR94, all rtems/score/CPUtypes.h are named
2020        rtems/score/types.h.
2021        * Per PR94, all rtems/score/CPUtypes.h are named
2022        rtems/score/types.h.
2023        * mpc8xx/timer/timer.c: Removed #warning declaring providing a
2024        default definition for the macros
2025        rtems_cpu_configuration_get_timer_least_valid and
2026        rtems_cpu_configuration_get_timer_average_overhead.
2027        * old-exceptions/rtems/score/cpu.h,
2028        new-exceptions/rtems/score/cpu.h: Account for name change.
2029
20302001-03-30      Eric Valette <valette@crf.canon.fr>
2031
2032        * mpc8xx/vectors/Makefile.am,
2033        mpc8xx/vectors/README, mpc8xx/vectors/align_h.S
2034        mpc8xx/vectors/vectors.S: These files were removed in support of
2035        switching the mpc8xx to the use the "new exception processing
2036        model."
2037        * configure.in, mpc6xx/mmu/bat.h, mpc8xx/Makefile.am,
2038        mpc8xx/clock/clock.c, mpc8xx/console-generic/console-generic.c,
2039        mpc8xx/include/mpc8xx.h, mpc8xx/mmu/mmu.c,
2040        new_exception_processing/cpu.h, shared/include/byteorder.h,
2041        wrapup/Makefile.am: This is conversion of the mpc8xx CPU to the "new
2042        exception processing model."
2043        * mpc8xx/exceptions/Makefile.am,
2044        mpc8xx/exceptions/asm_utils.S, mpc8xx/exceptions/raw_exception.c,
2045        mpc8xx/exceptions/raw_exception.h: New files.
2046
20472001-02-27      Ralf Corsepius <corsepiu@faw.uni-ulm.de>
2048
2049        * mpc505/ictrl/Makefile.am, mpc6xx/clock/Makefile.am,
2050        mpc6xx/exceptions/Makefile.am, mpc6xx/mmu/Makefile.am,
2051        mpc8xx/include/Makefile.am, new_exception_processing/Makefile.am,
2052        old_exception_processing/Makefile.am, pc403/ictrl/Makefile.am,
2053        shared/include/Makefile.am, shared/src/Makefile.am: Apply *_HEADERS
2054        instead of *H_FILES.
2055
20562001-01-03      Joel Sherrill <joel@OARcorp.com>
2057
2058        * new_exception_processing/cpu.h, old_exception_processing/cpu.c:
2059        old_exception_processing/cpu.h, Added _CPU_Initialize_vectors(). In
2060        particular, spurious vector initialization had to be moved on old
2061        exception processing model.
2062
20632000-11-09      Ralf Corsepius <corsepiu@faw.uni-ulm.de>
2064
2065        * Makefile.am: Use ... instead of RTEMS_TOPdir in ACLOCAL_AMFLAGS.
2066
20672000-11-02      Ralf Corsepius <corsepiu@faw.uni-ulm.de>
2068
2069        * Makefile.am: Switch to ACLOCAL_AMFLAGS = -I
2070        $(RTEMS_TOPdir)/aclocal.
2071
20722000-10-26      Ralf Corsepius <corsepiu@faw.uni-ulm.de>
2073
2074        * Makefile.am: ACLOCAL_AMFLAGS= -I $(RTEMS_TOPdir)/macros. Switch to
2075        GNU canonicalization.
2076
20772000-10-20      Joel Sherrill <joel@OARcorp.com>
2078
2079        * mpc8xx/console-generic/console-generic.c: Avoid use of BSP
2080        definitions and rely on the new routine
2081        mbx8xx_console_get_configuration() to get information.  This routine
2082        was formerly incorrectly called
2083        mbx8xx_console_use_maximum_buffer_size(). binding to the exception
2084        code.
2085        * configure.in, Makefile.am: Explicitly specify whether an
2086        RTEMS_CPU_MODEL is using old or new exception processing.  This is
2087        important because when building multilib, you do not know  the
2088        RTEMS_CPU_MODEL.  So everything built in a multilib'ed RTEMS must be
2089        independent of the exception model and allow for late binding to the
2090        exception code.
2091
20922000-10-18      Sergei Organov <osv@javad.ru>
2093
2094        * Added full support for MPC505.
2095        * configure.in, mpc505/Makefile.am: Modified to reflect ictrl
2096        addition.

2112        * mpc8xx/console-generic/console-generic.c: Removed include of
2113        <bsp.h> by adding BSP dependent routine
2114        mbx8xx_console_use_maximum_buffer_size() which can be hard coded or
2115        check non-volatile memory for configuration.
2116        * mpc8xx/console-generic/console-generic.c: Removed warnings.
2117        * mpc6xx/clock/c_clock.h: Removed commented out reference to
2118        <bsp.h>.
2119        * mpc6xx/timer/timer.c, mpc6xx/timer/timer.c: Ditto.
2120        * mpc6xx/clock/c_clock.c, mpc6xx/clock/c_clock.h: Removed use of
2121        bsp.h and replaced it with use of proper interfaces or explicit
2122        externs of required functions and data.

2141        * mpc8xx/console-generic/console-generic.c: Add support for
2142        configuration parameters in NVRAM
2143

2145
2146        * mpx8xx/console-generic/console-generic.c(m8xx_uart_pollWrite):
2147        Flush actual buffer.
2148        * mpx8xx/console-generic/console-generic.c: Addition of support for
2149        shared printk and no termios.

2152
2153        * mpc8xx/console-generic/console-generic.c: The printk/printf did
2154        not work when loaded by EPPCBUG. They did work when loaded with the
2155        BDM debugger.  I suspected EPPBUG  made some nasty things like
2156        patching Communication processor microcode...  Anyway, the attached
2157        patch: 1) Enables to have printk nearly immediately after boot, 2)
2158        Make printf work automagically (I do not know why except I make a
2159        different initialization for printk that should be overwritten by
2160        console init later ?) I let the default to be using EPPCBUG embedded
2161        firmware to boot and  using this printk early enabler code
2162        (LOADED_BY_EPPCBUG and  EARLY_CONSOLE) are on.
