12        new-exceptions/raw_exception.h, new-exceptions/bspsupport/irq_supp.h,
13        shared/include/cpuIdent.c: Removed warnings. Split
14        bsp_irq_dispatch_list to allow non-standard/non-existant pics to call
15        with interrupts off.

19        PR 1385/cpukit
20        * mpc5xx/irq/irq_asm.S: When the type rtems_boolean was switched to the
21        C99 bool, the size changed from 4 bytes to 1 byte. The interrupt
22        dispatching code accesses two boolean variables for scheduling
23        purposes and the assembly implementations of this code did not get
24        updated.
25
262009-02-13      Joel Sherrill <joel.sherrill@OARcorp.com>

76        The Shared Memory Driver no longer requires the special IOCTL in
77        Clock_control. This was a hack which has existed since before the
78        Classic API Timer Manager was implemented. All implementations of and
79        references to Clock_control were removed.
80

149        code so that a BSP can choose to hook the timer exception
150        directly rather than going through the interrupt dispatcher.
151
1522008-07-21      Till Straumann <strauman@slac.stanford.edu>
153
154        * new-exceptions/raw_exception,h,

157       
1582008-07-18      Sebastian Huber <sebastian.huber@embedded-brains.de>
159
160        * shared/include/powerpc-utility.h: Changed special purpose register
161        inline functions to macros.  Added macros to set and clear bits for
162        SPRs and DCRs.
163
164        * new-exceptions/raw_exception.c: The watchdog exception for e200 is
165        now asynchronous.

168
169        * mpc55xx/include/watchdog.h: New file.

172
1732008-07-18      Thomas Doerfler <thomas.doerfler@embedded-brains.de>
174
175        * mpc83xx/network/tsec.c: Initialize PHY registers late enough,
176        so that phy access is possible
177
1782008-07-17      Thomas Doerfler <thomas.doerfler@embedded-brains.de>
179
180        * rtems/powerpc/powerpc.h:
181        ppc405 uses definitions distinct from ppc403 now
182        * shared/src/cache_.h: Use correct powerpc.h to get cache attributes
183
184       
1852008-07-17      Thomas Doerfler <thomas.doerfler@embedded-brains.de>
186
187        * shared/include/powerpc-utility.h:
188        Fixed typo in access macros for device control registers (DCR)
189       
1902008-07-16      Till Straumann <strauman@slac.stanford.edu>
191
192        * new-exceptions/bspsupport/vectors_init.c: added
193        features to C_exception_handler() (the default global
194        handler):
195         - try to catch recursion
196         - print info about context where the exception occurred
197           (ISR or task with task ID).
198         - suspend offending task rather than spinning forever.
199       
2002008-07-16      Till Straumann <strauman@slac.stanford.edu>
201
202        * new-exceptions/bspsupport/vectors_init.c: must not
203        align start of stack downwards (we don't 'own' memory
204        below start). Instead, use original boundaries but
205        align the stack pointer as required.
206
207        Added test to verify that R13 was loaded with _SDA_BASE_
208        during early initialization (low-level assembly code
209        relies on it).
210
2112008-07-16      Till Straumann <strauman@slac.stanford.edu>
212
213        * new-exceptions/cpu.c: propagate R2 to all task contexts
214        even if the ABI is SVR4. Cannot hurt...
215
2162008-07-16      Till Straumann <strauman@slac.stanford.edu>
217
218        * new-exceptions/cpu.c: use ppc_interrupt_get_disable_mask()
219        to determine which bits to set/clear from _CPU_Context_Initialize().
220
2212008-07-16      Till Straumann <strauman@slac.stanford.edu>
222
223        * new-exceptions/bspsupport/ppc_exc_asm_macros.h: Added
224        a test to TEST_LOCK_crit so that a context switch is
225        always prevented if MSR_CE is not set in the interrupt mask.
226        (Support mode where the user wants to leave MSR_CE always enabled
227        but abstains from calling OS primitives from the exception
228        handler.)
229
2302008-07-16      Till Straumann <strauman@slac.stanford.edu>
231
232        * shared/include/powerpc-utility.h: Added
233        GET_INTERRUPT_MASK macro.
234

254
255        * shared/include/powerpc-utility.h: Exchanged ASM and non ASM code
256        sections.
257
258        * rtems/powerpc/powerpc.h, shared/src/cache.c, shared/src/cache_.h:
259        New defines PPC_NO_CACHE_ALIGNMENT and PPC_NO_CACHE_ALIGNMENT_POWER for
260        CPUs with no cache.  Provide default implementations for all cache
261        functions.
262
263        * mpc83xx/include/gtm.h, mpc83xx/gtm/gtm.c: New files.
264
2652008-07-14      Thomas Doerfler <thomas.doerfler@embedded-brains.de>

271        * shared/include/cpuIdent.c, shared/include/cpuIdent.h,
272        * shared/include/powerpc-utility.h:
273        Added support for PPC405EX (contributed by Michael Hamel)
274       
2752008-07-11      Sebastian Huber <sebastian.huber@embedded-brains.de>
276
277        * Makefile.am: Install powerpc-utility.h.
278
279        * shared/include/cpuIdent.h, shared/include/cpuIdent.c: Added e200 and
280        e300 features.
281
282        * new-exceptions/cpu.c: Removed PR288 bugfix check.
283
284        * new-exceptions/e500_raw_exc_init.c: Added initialization for e200.
285        Set IVPR register for e200 and e500 to ppc_exc_vector_base.
286
287        * new-exceptions/raw_exception.c, new-exceptions/raw_exception.h: Added
288        vector categories for e200 and e300 cores.  Added global variable
289        ppc_exc_vector_base for CPUs with IVPR register.
290
291        * new-exceptions/bspsupport/ppc_exc.S,
292        * new-exceptions/bspsupport/ppc_exc_asm_macros.h,
293        * new-exceptions/bspsupport/ppc_exc_bspsupp.h,
294        * new-exceptions/bspsupport/ppc_exc_hdl.c,
295        * new-exceptions/bspsupport/vectors.h,
296        * new-exceptions/bspsupport/vectors_init.c:
297        Conistent code layout in most assember code sections and usage of
298        defines for registers.  Usage of standard header files to avoid
299        multiple definitions.
300       
301        Optimized exception code: Removed many branches and exploit branch
302        prediction for asynchronous exceptions, moved common wrap code into
303        WRAP macro to eliminate branch, static initialization of the handler
304        table with a default handler to eliminate the test if a handler is
305        present.  Register CR6 is no more cleared because the exeption handler
306        functions are not variadic.
307       
308        New method to switch to the interrupt stack. It will be tested if the
309        exception stack pointer is already inside the interrupt stack area.  It
310        is no more necessary to disable interrupts.  The SPRG1 and SPRG2 are
311        used to store the initial interrupt stack pointer and the interrupt
312        stack memory area start.
313
314        Removed variable ppc_exc_msr_irq_mask and use general interrupt disable
315        mask from SPRG0 instead.
316
317        New initialization routine ppc_exc_initialize() for bsp_start().  It
318        takes the interrupt disable mask, interrupt stack start and size as
319        parameters.
320
321        Added packed prologues for CPUs with IVPR and IVOR registers to save
322        memory space.
323
324        Reverted ppc_exc_crit_always_enabled change from yesterday.
325
326        WARNING: Tests with critical interrupt exceptions crash the system at
327        least on MPC8313ERDB and MPC8349EAMDS.  There may be somewhere a
328        serious bug with the new code.
329
3302008-07-10      Till Straumann <strauman@slac.stanford.edu>
331
332        * mpc6xx/mmu/pte121.c: use general "memory" clobber
333        rather than memory input operand in inline assembly
334        ("m" doesn't do what the manual says; see discussion
335        on gcc mailing list around 2008/3/30)
336
3372008-07-10      Till Straumann <strauman@slac.stanford.edu>
338
339        * ChangeLog, mpc8xx/clock/clock.c, ppc403/clock/clock.c,
340        ppc403/irq/ictrl.h, rtems/powerpc/powerpc.h:
341        Removed all macro definitions which depended on
342        the compiler defining a PPC CPU-model dependent
343        symbol from files in cpukit.
344        Macros which were not used by cpukit have been
345        moved to libcpu/powerpc/rtems/powerpc/powerpc.h.
346
3472008-07-10      Till Straumann <strauman@slac.stanford.edu>
348
349        * new-exceptions/bspsupport/README,
350        new-exceptions/bspsupport/ppc_exc.S,
351        new-exceptions/bspsupport/ppc_exc_asm_macros.h,
352        new-exceptions/bspsupport/ppc_exc_bspsupp.h,
353        new-exceptions/bspsupport/ppc_exc_hdl.c,
354        new-exceptions/bspsupport/vectors_init.c:
355        Fixed and enabled stack-switching algorithm which figures out
356        if we already run on the ISR stack rather than relying on the
357        _ISR_Nest_level.
358        Added 'ppc_exc_crit_always_enabled' variable which defines
359        the semantics of critical interrupts.
360        Let asynchronous machine-check handling never call the dispatcher.
361        We don't want to disable MSR_ME ever (to avoid checkstops)
362        and hence asynchronous MEs must not use OS services anyways.
363
3642008-07-09      Sebastian Huber <sebastian.huber@embedded-brains.de>
365
366        * shared/include/powerpc-utility.h: Includes standard header files,
367        provides common assembler macros and inline functions for low-level
368        code.
369
3702008-05-23      Thomas Doerfler <Thomas.Doerfler@embedded-brains.de>

373        disabled debugging output, reduced rx interrupt coalescing
374
3752008-05-22      Till Straumann <strauman@slac.stanford.edu>

436
437        * new-exceptions/bspsupport/irq.c: don't disable irqs
438        at the interrupt controller (PIC) during initialization -- this
439        caused problems where some BSPs's BSP_disable_irq_at_pic() routine
440        did not ignore IRQ lines associated with cascaded PICs.
441        Rely on the BSP (BSP_setup_the_pic()) to provide a good

450        Thomas Doerfler clarified (thanks!) that raising an
451        exception and executing the 1st instruction is not
452        an atomical operation. I added a fix to the code that
453        checks if a lower-priority interrupt is under way:
454        we now not only test if the 'lock' variable was set
455        but also check if the interrupted PC points to the
456        'write lock' instruction.
457        Added more comments and updated README.

671        #ifdef <cpu_flavor> with <cpu_flavor> in the symbol name.
672        If the special flavor __ppc_generic is effective the ALL
673        vector symbols are available and ppc_vector_is_valid() works
674        for all supported CPUs (run-time check).
675        This is work towards a #ifdef <cpu_flavor> free libcpu and

694        pretasking_hook, predriver_hook, postdriver_hook, idle_task,
695        do_zero_of_workspace, extra_mpci_receive_server_stack,
696        stack_allocate_hook, and stack_free_hook. As a side-effect of this

719
720        * mpc6xx/clock/c_clock.c, mpc6xx/clock/c_clock.h:

731
732        * shared/include/cpuIdent.h, shared/include/cpuIdent.c:
733        Added a simple 'feature check' facility. Code should
734        not check for a particular CPU type if possible but
735        check the respective feature bit (e.g., 'has_altivec').
736        This makes it much less cumbersome to add more CPU

1986
1987        * mpc8xx/console-generic/console-generic.c: Bug found by Yacine
1988        <elkolli@crf.canon.fr> where the initialization or irq data
1989        structure was incomplete in case a SMC channel was used first and
1990        later a SCC one.

19922001-05-17      Joel Sherrill <joel@OARcorp.com>
1993
1994        * mpc6xx/exceptions/raw_exception.c, pc6xx/mmu/pte121.c: Modified
1995        slightly to reflect recent PowerPC re-organization and avoid
1996        warnings.
1997
19982001-05-15      Till Straumann <strauman@slac.stanford.edu>
1999
2000        * mpc6xx/mmu/pte121.c, mpc6xx/mmu/pte121.h: New files. Missed in
2001        merge of PR213.
2002
20032001-05-14      Till Straumann <strauman@slac.stanford.edu>
2004
2005        * rtems/powerpc/registers.h, rtems/score/ppc.h: Per PR213, add  the
2006        following: - support for the MPC74000 (AKA G4); there is no AltiVec
2007        support yet, however. - the cache flushing assembly code uses
2008        hardware-flush on the G4. Also, a couple of hardcoded numerical
2009        values were replaced by more readable symbolic constants. - extended
2010        interrupt-disabled code section so enclose the entire cache
2011        flush/invalidate procedure (as recommended by the book). This is not
2012        (latency) critical as it is only used by init code but prevents
2013        possible corruption. - Trivial page table support as been added.
2014        (1:1 effective-virtual-physical address mapping which is only useful
2015        only on CPUs which feature hardware TLB replacement, e.g. >604.
2016        This allows for write-protecting memory regions, e.g. text/ro-data
2017        which makes catching corruptors a lot easier. It also frees one
2018        DBAT/IBAT and gives more flexibility for setting up address maps :
2019        -) - setdbat() allows changing BAT0 also (since the BSP may use a
2020        page table, BAT0 could be available...). - asm_setdbatX() violated
2021        the SVR ABI by using r20 as a scratch register; changed for r0 -
2022        according to the book, a context synchronizing instruction is
2023        necessary prior to and after changing a DBAT -> isync added
2024        * new-exceptions/cpu.c: Per PR211 fix saving/restoring floating
2025        point context.  The fpsave and fprestore routines are only used in a
2026        executing context which _is_ fp and hence has the FPU enabled. The
2027        current behavior required the FPU always to be on which is very
2028        dangerous if lazy context switching is used.   [Joel Note: Some
2029        ports explicitly enabled the FPU in the FP save and restore routines
2030        to avoid this.] The patch also makes sure (on powerpc only) that the
2031        FPU is disabled for integer tasks. Note that this is crucial if
2032        deferred fp context switching is used. Otherwise, fp context
2033        corruption may go undetected! Also note that even tasks which merely
2034        push/pop FP registers to/from the stack without modifying them still
2035        MUST be FP tasks - otherwise (if lazy FP context switching is used),
2036        FP register corruption (of other, FP, tasks may occur)! Furthermore,
2037        (on PPC) by default, lazy FP context save/restore is _disabled_.
2038        * shared/include/io.h: Per PR215 address the following issues: -
2039        _IO_BASE, _ISA_MEM_BASE and PCI_DRAM_OFFSET are no longer defined by
2040        libcpu (powerpc/shared/include/io.h) but by the BSP (who is the only
2041        one to know the values) - the affected BSP (shared/motorola) headers
2042        have been fixed in a separate "libbsp/powerpc/shared" patch. - the
2043        DEC 21140 driver (libchip/network/dec21140.c) has been fixed to use
2044        PCI_DRAM_OFFSET instead of PREP_PCI_DRAM_OFFSET. and PCI_MEM_BASE
2045        instead of PREP_ISA_MEM_BASE. PCI_MEM_BASE is to be defined by the
2046        BSP who is using this driver. - the DEC driver also has been fixed
2047        to use the newer rtems_bsp_delay_in_bus_cycles() instead of the
2048        obsolete delay_in_bus_cycles().

2057
20582001-04-03      Joel Sherrill <joel@OARcorp.com>
2059
2060        * Closed PR57.  The hack is OK as it allows a BSP to override or not
2061        at its discretion.
2062        * Per PR94, all rtems/score/CPUtypes.h are named
2063        rtems/score/types.h.
2064        * Per PR94, all rtems/score/CPUtypes.h are named
2065        rtems/score/types.h.

2093        mpc6xx/exceptions/Makefile.am, mpc6xx/mmu/Makefile.am,
2094        mpc8xx/include/Makefile.am, new_exception_processing/Makefile.am,
2095        old_exception_processing/Makefile.am, pc403/ictrl/Makefile.am,
2096        shared/include/Makefile.am, shared/src/Makefile.am: Apply *_HEADERS
2097        instead of *H_FILES.

20992001-01-03      Joel Sherrill <joel@OARcorp.com>
2100
2101        * new_exception_processing/cpu.h, old_exception_processing/cpu.c:
2102        old_exception_processing/cpu.h, Added _CPU_Initialize_vectors(). In
2103        particular, spurious vector initialization had to be moved on old
2104        exception processing model.
2105
21062000-11-09      Ralf Corsepius <corsepiu@faw.uni-ulm.de>
2107
2108        * Makefile.am: Use ... instead of RTEMS_TOPdir in ACLOCAL_AMFLAGS.
2109
21102000-11-02      Ralf Corsepius <corsepiu@faw.uni-ulm.de>
2111
2112        * Makefile.am: Switch to ACLOCAL_AMFLAGS = -I
2113        $(RTEMS_TOPdir)/aclocal.
2114
21152000-10-26      Ralf Corsepius <corsepiu@faw.uni-ulm.de>
2116
2117        * Makefile.am: ACLOCAL_AMFLAGS= -I $(RTEMS_TOPdir)/macros. Switch to
2118        GNU canonicalization.
2119
21202000-10-20      Joel Sherrill <joel@OARcorp.com>
2121
2122        * mpc8xx/console-generic/console-generic.c: Avoid use of BSP
2123        definitions and rely on the new routine
2124        mbx8xx_console_get_configuration() to get information.  This routine
2125        was formerly incorrectly called
2126        mbx8xx_console_use_maximum_buffer_size(). binding to the exception
2127        code.
2128        * configure.in, Makefile.am: Explicitly specify whether an
2129        RTEMS_CPU_MODEL is using old or new exception processing.  This is
2130        important because when building multilib, you do not know  the
2131        RTEMS_CPU_MODEL.  So everything built in a multilib'ed RTEMS must be
2132        independent of the exception model and allow for late binding to the
2133        exception code.
2134
21352000-10-18      Sergei Organov <osv@javad.ru>
2136
2137        * Added full support for MPC505.
2138        * configure.in, mpc505/Makefile.am: Modified to reflect ictrl
2139        addition.
2140        * old_exception_processing/Makefile.am: Account for ppc_offs.h.
2141        * old_exception_processing/cpu_asm.S: Offsets moved to ppc_offs.h.
2142        * mpc505/timer/timer.c: Use <rtems.h>, not "rtems.h".
2143        * mpc505/vectors/vectors.S: Now use constants for exception numbers.
2144        * mpc505/ictrl: New directory.
2145        * old_exception_processing/ppc_offs.h: New file.
2146        * old_exception_processing/cpu.h: Make Nest and Disable levels
2147        volatile.
2148        * mpc505/vectors/Makefile.am: alignment exception handler now
2149        included.
2150        * mpc505/ictrl/Makefile.am,
2151        mpc505/ictrl/ictrl.c, mpc505/ictrl/ictrl.h: New files.
2152
21532000-10-18      Joel Sherrill <joel@OARcorp.com>
2154
2155        * mpc8xx/console-generic/console-generic.c: Removed include of
2156        <bsp.h> by adding BSP dependent routine
2157        mbx8xx_console_use_maximum_buffer_size() which can be hard coded or
2158        check non-volatile memory for configuration.
2159        * mpc8xx/console-generic/console-generic.c: Removed warnings.
2160        * mpc6xx/clock/c_clock.h: Removed commented out reference to
2161        <bsp.h>.
2162        * mpc6xx/timer/timer.c, mpc6xx/timer/timer.c: Ditto.
2163        * mpc6xx/clock/c_clock.c, mpc6xx/clock/c_clock.h: Removed use of
2164        bsp.h and replaced it with use of proper interfaces or explicit
2165        externs of required functions and data.
2166

21822000-08-11      Charles-Antoine Gauthier  <charles.gauthier@nrc.ca>
2183
2184        * mpc8xx/console-generic/console-generic.c: Add support for
2185        configuration parameters in NVRAM
2186
21872000-08-10      Charles-Antoine Gauthier  <charles.gauthier@nrc.ca>
2188
2189        * mpx8xx/console-generic/console-generic.c(m8xx_uart_pollWrite):
2190        Flush actual buffer.
2191        * mpx8xx/console-generic/console-generic.c: Addition of support for
2192        shared printk and no termios.
2193
21942000-06-08      Eric Valette <valette@crf.canon.fr>
2195
2196        * mpc8xx/console-generic/console-generic.c: The printk/printf did
2197        not work when loaded by EPPCBUG. They did work when loaded with the
2198        BDM debugger.  I suspected EPPBUG  made some nasty things like
2199        patching Communication processor microcode...  Anyway, the attached
2200        patch: 1) Enables to have printk nearly immediately after boot, 2)
2201        Make printf work automagically (I do not know why except I make a
2202        different initialization for printk that should be overwritten by
2203        console init later ?) I let the default to be using EPPCBUG embedded
2204        firmware to boot and  using this printk early enabler code
2205        (LOADED_BY_EPPCBUG and  EARLY_CONSOLE) are on.
