284
285        * new-exceptions/bspsupport/vectors_init.c: added
286        features to C_exception_handler() (the default global
287        handler):
288         - try to catch recursion
289         - print info about context where the exception occurred
290           (ISR or task with task ID).
291         - suspend offending task rather than spinning forever.
292       
2932008-07-16      Till Straumann <strauman@slac.stanford.edu>
294
295        * new-exceptions/bspsupport/vectors_init.c: must not
296        align start of stack downwards (we don't 'own' memory
297        below start). Instead, use original boundaries but
298        align the stack pointer as required.
299
300        Added test to verify that R13 was loaded with _SDA_BASE_
301        during early initialization (low-level assembly code
302        relies on it).
303
3042008-07-16      Till Straumann <strauman@slac.stanford.edu>
305
306        * new-exceptions/cpu.c: propagate R2 to all task contexts
307        even if the ABI is SVR4. Cannot hurt...
308
3092008-07-16      Till Straumann <strauman@slac.stanford.edu>
310
311        * new-exceptions/cpu.c: use ppc_interrupt_get_disable_mask()
312        to determine which bits to set/clear from _CPU_Context_Initialize().
313
3142008-07-16      Till Straumann <strauman@slac.stanford.edu>
315
316        * new-exceptions/bspsupport/ppc_exc_asm_macros.h: Added
317        a test to TEST_LOCK_crit so that a context switch is
318        always prevented if MSR_CE is not set in the interrupt mask.
319        (Support mode where the user wants to leave MSR_CE always enabled
320        but abstains from calling OS primitives from the exception
321        handler.)
322
3232008-07-16      Till Straumann <strauman@slac.stanford.edu>
324
325        * shared/include/powerpc-utility.h: Added

372        * shared/include/cpuIdent.h, shared/include/cpuIdent.c: Added e200 and
373        e300 features.
374
375        * new-exceptions/cpu.c: Removed PR288 bugfix check.
376
377        * new-exceptions/e500_raw_exc_init.c: Added initialization for e200.
378        Set IVPR register for e200 and e500 to ppc_exc_vector_base.
379
380        * new-exceptions/raw_exception.c, new-exceptions/raw_exception.h: Added
381        vector categories for e200 and e300 cores.  Added global variable
382        ppc_exc_vector_base for CPUs with IVPR register.
383
384        * new-exceptions/bspsupport/ppc_exc.S,
385        * new-exceptions/bspsupport/ppc_exc_asm_macros.h,

388        * new-exceptions/bspsupport/vectors.h,
389        * new-exceptions/bspsupport/vectors_init.c:
390        Conistent code layout in most assember code sections and usage of
391        defines for registers.  Usage of standard header files to avoid
392        multiple definitions.
393       
394        Optimized exception code: Removed many branches and exploit branch
395        prediction for asynchronous exceptions, moved common wrap code into
396        WRAP macro to eliminate branch, static initialization of the handler
397        table with a default handler to eliminate the test if a handler is
398        present.  Register CR6 is no more cleared because the exeption handler
399        functions are not variadic.
400       
401        New method to switch to the interrupt stack. It will be tested if the
402        exception stack pointer is already inside the interrupt stack area.  It
403        is no more necessary to disable interrupts.  The SPRG1 and SPRG2 are
404        used to store the initial interrupt stack pointer and the interrupt
405        stack memory area start.
406
407        Removed variable ppc_exc_msr_irq_mask and use general interrupt disable
408        mask from SPRG0 instead.
409
410        New initialization routine ppc_exc_initialize() for bsp_start().  It
411        takes the interrupt disable mask, interrupt stack start and size as
412        parameters.
413
414        Added packed prologues for CPUs with IVPR and IVOR registers to save
415        memory space.
416
417        Reverted ppc_exc_crit_always_enabled change from yesterday.
418
419        WARNING: Tests with critical interrupt exceptions crash the system at
420        least on MPC8313ERDB and MPC8349EAMDS.  There may be somewhere a
421        serious bug with the new code.

425        * mpc6xx/mmu/pte121.c: use general "memory" clobber
426        rather than memory input operand in inline assembly

434        Removed all macro definitions which depended on
435        the compiler defining a PPC CPU-model dependent
436        symbol from files in cpukit.
437        Macros which were not used by cpukit have been
438        moved to libcpu/powerpc/rtems/powerpc/powerpc.h.

447        new-exceptions/bspsupport/vectors_init.c:
448        Fixed and enabled stack-switching algorithm which figures out
449        if we already run on the ISR stack rather than relying on the
450        _ISR_Nest_level.
451        Added 'ppc_exc_crit_always_enabled' variable which defines
452        the semantics of critical interrupts.
453        Let asynchronous machine-check handling never call the dispatcher.
454        We don't want to disable MSR_ME ever (to avoid checkstops)
455        and hence asynchronous MEs must not use OS services anyways.

543        Thomas Doerfler clarified (thanks!) that raising an
544        exception and executing the 1st instruction is not
545        an atomical operation. I added a fix to the code that
546        checks if a lower-priority interrupt is under way:
547        we now not only test if the 'lock' variable was set

1978        context save/restore on a double precision PowerPC machine does not
1979        only result in rounding errors but also screws up the FPSCR

19992001-11-07      Joel Sherrill <joel@OARcorp.com>
2000
2001        * configure.ac: Delete the commented out line that said that the
2002        mpc8260 used the old exception processing model.  This line also
2003        appears to have caused ppc603e to miss this test.
2004
20052001-10-29      Joel Sherrill <joel@OARcorp.com>

2079
2080        * mpc8xx/console-generic/console-generic.c: Bug found by Yacine
2081        <elkolli@crf.canon.fr> where the initialization or irq data

20852001-05-17      Joel Sherrill <joel@OARcorp.com>
2086
2087        * mpc6xx/exceptions/raw_exception.c, pc6xx/mmu/pte121.c: Modified

2090
20912001-05-15      Till Straumann <strauman@slac.stanford.edu>
2092

2095
20962001-05-14      Till Straumann <strauman@slac.stanford.edu>
2097
2098        * rtems/powerpc/registers.h, rtems/score/ppc.h: Per PR213, add  the
2099        following: - support for the MPC74000 (AKA G4); there is no AltiVec
2100        support yet, however. - the cache flushing assembly code uses
2101        hardware-flush on the G4. Also, a couple of hardcoded numerical
2102        values were replaced by more readable symbolic constants. - extended
2103        interrupt-disabled code section so enclose the entire cache
2104        flush/invalidate procedure (as recommended by the book). This is not
2105        (latency) critical as it is only used by init code but prevents
2106        possible corruption. - Trivial page table support as been added.
2107        (1:1 effective-virtual-physical address mapping which is only useful
2108        only on CPUs which feature hardware TLB replacement, e.g. >604.
2109        This allows for write-protecting memory regions, e.g. text/ro-data
2110        which makes catching corruptors a lot easier. It also frees one
2111        DBAT/IBAT and gives more flexibility for setting up address maps :
2112        -) - setdbat() allows changing BAT0 also (since the BSP may use a
2113        page table, BAT0 could be available...). - asm_setdbatX() violated
2114        the SVR ABI by using r20 as a scratch register; changed for r0 -
2115        according to the book, a context synchronizing instruction is
2116        necessary prior to and after changing a DBAT -> isync added
2117        * new-exceptions/cpu.c: Per PR211 fix saving/restoring floating
2118        point context.  The fpsave and fprestore routines are only used in a
2119        executing context which _is_ fp and hence has the FPU enabled. The
2120        current behavior required the FPU always to be on which is very
2121        dangerous if lazy context switching is used.   [Joel Note: Some
2122        ports explicitly enabled the FPU in the FP save and restore routines
2123        to avoid this.] The patch also makes sure (on powerpc only) that the
2124        FPU is disabled for integer tasks. Note that this is crucial if
2125        deferred fp context switching is used. Otherwise, fp context
2126        corruption may go undetected! Also note that even tasks which merely
2127        push/pop FP registers to/from the stack without modifying them still
2128        MUST be FP tasks - otherwise (if lazy FP context switching is used),
2129        FP register corruption (of other, FP, tasks may occur)! Furthermore,
2130        (on PPC) by default, lazy FP context save/restore is _disabled_.
2131        * shared/include/io.h: Per PR215 address the following issues: -
2132        _IO_BASE, _ISA_MEM_BASE and PCI_DRAM_OFFSET are no longer defined by
2133        libcpu (powerpc/shared/include/io.h) but by the BSP (who is the only
2134        one to know the values) - the affected BSP (shared/motorola) headers
2135        have been fixed in a separate "libbsp/powerpc/shared" patch. - the
2136        DEC 21140 driver (libchip/network/dec21140.c) has been fixed to use
2137        PCI_DRAM_OFFSET instead of PREP_PCI_DRAM_OFFSET. and PCI_MEM_BASE
2138        instead of PREP_ISA_MEM_BASE. PCI_MEM_BASE is to be defined by the
2139        BSP who is using this driver. - the DEC driver also has been fixed
2140        to use the newer rtems_bsp_delay_in_bus_cycles() instead of the
2141        obsolete delay_in_bus_cycles().

2148
2149        * shared/include/cpu.h: Added ifndef ASM.
2150
21512001-04-03      Joel Sherrill <joel@OARcorp.com>
2152
2153        * Closed PR57.  The hack is OK as it allows a BSP to override or not
2154        at its discretion.
2155        * Per PR94, all rtems/score/CPUtypes.h are named
2156        rtems/score/types.h.
2157        * Per PR94, all rtems/score/CPUtypes.h are named
2158        rtems/score/types.h.
2159        * mpc8xx/timer/timer.c: Removed #warning declaring providing a
2160        default definition for the macros
2161        rtems_cpu_configuration_get_timer_least_valid and
2162        rtems_cpu_configuration_get_timer_average_overhead.
2163        * old-exceptions/rtems/score/cpu.h,

2169        mpc8xx/vectors/README, mpc8xx/vectors/align_h.S
2170        mpc8xx/vectors/vectors.S: These files were removed in support of
2171        switching the mpc8xx to the use the "new exception processing
2172        model."
2173        * configure.in, mpc6xx/mmu/bat.h, mpc8xx/Makefile.am,

2176        new_exception_processing/cpu.h, shared/include/byteorder.h,
2177        wrapup/Makefile.am: This is conversion of the mpc8xx CPU to the "new

2188        old_exception_processing/Makefile.am, pc403/ictrl/Makefile.am,
2189        shared/include/Makefile.am, shared/src/Makefile.am: Apply *_HEADERS

2191
21922001-01-03      Joel Sherrill <joel@OARcorp.com>
2193
2194        * new_exception_processing/cpu.h, old_exception_processing/cpu.c:
2195        old_exception_processing/cpu.h, Added _CPU_Initialize_vectors(). In
2196        particular, spurious vector initialization had to be moved on old
2197        exception processing model.

2212
22132000-10-20      Joel Sherrill <joel@OARcorp.com>
2214
2215        * mpc8xx/console-generic/console-generic.c: Avoid use of BSP
2216        definitions and rely on the new routine
2217        mbx8xx_console_get_configuration() to get information.  This routine
2218        was formerly incorrectly called
2219        mbx8xx_console_use_maximum_buffer_size(). binding to the exception
2220        code.
2221        * configure.in, Makefile.am: Explicitly specify whether an
2222        RTEMS_CPU_MODEL is using old or new exception processing.  This is
2223        important because when building multilib, you do not know  the
2224        RTEMS_CPU_MODEL.  So everything built in a multilib'ed RTEMS must be
2225        independent of the exception model and allow for late binding to the
2226        exception code.
2227
22282000-10-18      Sergei Organov <osv@javad.ru>
2229

2232        addition.
2233        * old_exception_processing/Makefile.am: Account for ppc_offs.h.
2234        * old_exception_processing/cpu_asm.S: Offsets moved to ppc_offs.h.
2235        * mpc505/timer/timer.c: Use <rtems.h>, not "rtems.h".
2236        * mpc505/vectors/vectors.S: Now use constants for exception numbers.
2237        * mpc505/ictrl: New directory.
2238        * old_exception_processing/ppc_offs.h: New file.
2239        * old_exception_processing/cpu.h: Make Nest and Disable levels
2240        volatile.
2241        * mpc505/vectors/Makefile.am: alignment exception handler now
2242        included.
2243        * mpc505/ictrl/Makefile.am,

22462000-10-18      Joel Sherrill <joel@OARcorp.com>
2247
2248        * mpc8xx/console-generic/console-generic.c: Removed include of
2249        <bsp.h> by adding BSP dependent routine
2250        mbx8xx_console_use_maximum_buffer_size() which can be hard coded or
2251        check non-volatile memory for configuration.
2252        * mpc8xx/console-generic/console-generic.c: Removed warnings.
2253        * mpc6xx/clock/c_clock.h: Removed commented out reference to
2254        <bsp.h>.
2255        * mpc6xx/timer/timer.c, mpc6xx/timer/timer.c: Ditto.
2256        * mpc6xx/clock/c_clock.c, mpc6xx/clock/c_clock.h: Removed use of
2257        bsp.h and replaced it with use of proper interfaces or explicit
2258        externs of required functions and data.

2276
2277        * mpc8xx/console-generic/console-generic.c: Add support for

2288
2289        * mpc8xx/console-generic/console-generic.c: The printk/printf did
2290        not work when loaded by EPPCBUG. They did work when loaded with the
2291        BDM debugger.  I suspected EPPBUG  made some nasty things like
2292        patching Communication processor microcode...  Anyway, the attached
2293        patch: 1) Enables to have printk nearly immediately after boot, 2)
2294        Make printf work automagically (I do not know why except I make a
2295        different initialization for printk that should be overwritten by
2296        console init later ?) I let the default to be using EPPCBUG embedded
2297        firmware to boot and  using this printk early enabler code
2298        (LOADED_BY_EPPCBUG and  EARLY_CONSOLE) are on.
