        !            12:        tme_bus_addr32_t.  In struct tme_ncr5380, store an actual TLB entry
        !            13:        instead of a pointer to an allocated entry. 
        !            14:        (_tme_ncr5380_bus_tlb_fill): Replaced the call to tme_bus_tlb_back()
        !            15:        with a plain structure copy. 
        !            16:        (_tme_ncr5380_connection_make_bus): Call tme_bus_device_tlb_set_add()
        !            17:        to add the TLB entry to the connection. 
        !            18: 
        !            19:        * ic/ncr53c9x.c: Changed or cast various tme_bus_addr_t to
        !            20:        tme_bus_addr32_t.  In struct tme_ncr53c9x, store an actual TLB entry
        !            21:        instead of a pointer to an allocated entry.  Added
        !            22:        tme_ncr53c9x_detected_scsi_reset.

        !            28:        FIFO head and tail. 
        !            29:        Replaced the call to tme_bus_tlb_back() with a plain structure copy. 
        !            30:        When a SCSI DMA cycle is transferring out to the SCSI bus, only
        !            31:        initially clear the SCSI DMA buffer if DMA is not running - if DMA is
        !            32:        running, and the data FIFO is empty, and the TLB entry doesn't support
        !            33:        fast reading, the code that sets up a transfer into the data FIFO
        !            34:        needs to know how much space is available in the data FIFO starting at
        !            35:        the tail, until the end of the data FIFO.  Also call

        !            45:        (_tme_z8530_intack): Fixed a bug where we would accept an interrupt
        !            46:        acknowledge even if the IEI pin was tied low.  Get the vector directly
        !            47:        from the channel B RR2. 
        !            48:        (_tme_z8530_bus_cycle): In TME_Z8530_WR0_CMD_RESET_IUS, no longer call
        !            49:        _tme_z8530_rr2_update().  The eventual interrupt check for
        !            50:        TME_Z8530_CALLOUT_INT will update RR2.

        !            70:        (tme_sparc32_external_check): 32-bit SPARCs default to no interrupt
        !            71:        acknowledge cycle.

        !          1035:        * ic/sparc/sparc-rc-insns.c (_tme_sparc_recode_recode): When recoding

        !          1037:        doing the full sign-extension to guest width in one place. 
        !          1038:        Added support for branch to .  timing loops.  When the PCs are not
        !          1039:        updated, in addition to checking that the PC advance is zero, check
        !          1040:        that the PC is in the guest PC register. 
        !          1041:

        !          1052:        * ic/sparc/sparc-execute.c: Now define tme_sparc_idle_pcs, instead of
        !          1053:        tme_sparc_idle_type_pc.  Now use TME_SPARC_HAVE_RECODE() to test for
        !          1054:        recode support.  Reworked idle handling.  Now, an idle type must mark
        !          1055:        two consecutive idles without a trap before we go idle.  This
        !          1056:        eliminates the race condition where we would trap, then resume in the
        !          1057:        idle loop past the point of no return of our going idle (i.e., before
        !          1058:        looping to check the possibly updated scheduler state again).  Also
        !          1059:        added support for marking idles in a true idle loop.  No longer go
        !          1060:        idle for the netbsd32-type-0 idle type in an annulled branch delay
        !          1061:        slot. 
        !          1062:        When recode is supported, before checking for a recode thunk, detect a
        !          1063:        control transfer target that is an idle PC, and mark the idle.  When
        !          1064:        recode is not supported, in the control transfer instruction handling,
        !          1065:        detect a control transfer target that is an idle PC, and mark the
        !          1066:        idle. 
        !          1067: 
        !          1068:        * ic/sparc/sparc-impl.h: Added macros for the new idle types, and

        !          1070:        Replaced TME_SPARC_IDLE_TYPES_SUPPORTED() with

        !          1072:        TME_SPARC_IDLE_STOP().  Added TME_SPARC_HAVE_RECODE().  In struct
        !          1073:        tme_sparc, added an instruction burst count for when idle.  Now track
        !          1074:        the number of idle marks made since the last trap, and multiple idle
        !          1075:        PCs. 
        !          1076: 
        !          1077:        * ic/sparc/sparc-insns.c: Now include <tme/misc.h>. 
        !          1078:        Now define a constant TME_SPARC_VERSION() around the instructions for
        !          1079:        the different architectures. 
        !          1080:        In all of the sparc32 instructions, renamed TME_SPARC_TRAP_ to
        !          1081:        TME_SPARC32_TRAP_. 
        !          1082:        (tme_sparc32_rdpsr): Removed the sunos32-type-0 idle type detection. 
        !          1083:        This idle type is now detected only in tme_sparc32_wrpsr(). 
        !          1084:        (tme_sparc32_wrpsr): Reworked all sparc32 idle type detection that
        !          1085:        keys off of a wrpsr.  Now use TME_SPARC32_CWP_UPDATE().

        !          1087:        (tme_sparc32_save_restore): Now use TME_SPARC32_CWP_UPDATE(). 
        !          1088:        [TME_HAVE_INT64_T]: Added the sparc64 instructions. 
        !          1089: 
        !          1090:        * ic/sparc/sparc-misc.c (_tme_sparc_idle_reset): Added.  All functions

        !          1092:        (tme_sparc_thread): Added support for the new idle types. 
        !          1093:        (tme_sparc_new): Initialize the idle instruction burst size.

        !          1095:        (tme_sparc64_trap): Traps always do a TME_SPARC_IDLE_STOP(). 
        !          1096:        (tme_sparc_ls_bus_fault): Fixed a bug where we wouldn't advance the
        !          1097:        cycle to get past the fault under TME_SPARC_LSINFO_NO_FAULT.  This
        !          1098:        caused fetches of annulled instructions that fault to loop forever. 
        !          1099:        (tme_sparc_fetch_nearby): Cleaned up the code that gets the current PC
        !          1100:        and the nearby PC, especially making sure that the offset remains
        !          1101:        signed after multiplying it by a sizeof(), and truncating the result
        !          1102:        to the correct address size.  Fixed a bug where we would assert() that
        !          1103:        the ITLB entry applies without checking if it's valid - for various
        !          1104:        reasons the ITLB might be the execute loop's itlb_invalid. 
        !          1105: 
        !          1106:        * ic/sparc/sparc-rc-insns.c (_tme_sparc_recode_recode): No longer
        !          1107:        check for the netbsd32-type-0 idle PC in a branch delay slot.  This

        !          1296:        Added struct tme_posix_memory_valids.  In struct tme_posix_memory,
        !          1297:        added a mutex.  Fixed a bug where the rwlock was a mutex.  Added

        !          1299:        bitmasks.  Added members for the current writable TLB size, and our

        !          1304:        the TLB entry in the hash set and clear the bit for the address' page

        !          1330:        in the instruction executor when recode is in use, moved the

        !          1336:        Use TME_SPARC_G0_OFFSET(ic) to find the globals. 
        !          1337:        [TME_HAVE_RECODE]: Now recode instructions, run recoded instructions

        !          1358:        overflow handling for the cc instructions.  Fixed a sparc64 bug where
        !          1359:        we would only set %icc.Z when the 64-bit result was zero. 
        !          1360:        In the load/store instructions, get the right address for the sparc64
        !          1361:        casa and casxa instructions, and when %pstate.AM is set.  Get the

        !          1363:        that will trigger a slow load/store.  Check the DTLB entry's context. 
        !          1364:        Added (tme_bus_addr${arch}_t) casts to the DTLB address check.  Check
        !          1365:        that the ASI mask in the DTLB entry allows fast transfers.  For a slow
        !          1366:        transfer, call the new tme_sparc${arch}_ls().  Now, allow the slow
        !          1367:        function to complete an alternate load.  Get the byte order of the

        !          1373:        to see if the address is misaligned.  Before the memory access, now
        !          1374:        call _tme_sparc${arch}_fpu_mem_fpreg() to check for any traps and to

        !          1388:        (tme_sparc${arch}_store): These functions are no longer called
        !          1389:        directly by instruction functions.  They now only do final loads and

        !          1391:        (tme_sparc${arch}_ls): Added.  This is the function called by

        !          1474:        the ic had a larger page size, because DTLB entries for writing were
        !          1475:        never for a full page (since we made the fixed sparc recode page size
        !          1476:        the validity size for cacheable memory, DTLB entries were never bigger
        !          1477:        than that). 
        !          1478:        For the v9 movr, fixed bugs where we had the wrong opcode and didn't
        !          1479:        set the right conditions thunk.  Added support for the v9 ld*a
        !          1480:        instructions, because they may be used for speculative loads, which we
        !          1481:        do want to handle with recode read instructions. 
        !          1482:        For BPcc and Bicc, extract the branch displacement using 32-bit types
        !          1483:        for as long as possible.  Now test TME_SPARC_RECODE_INSN_UPDATE_INSN
        !          1484:        to see if an instruction always or sometimes needs an assist, instead
        !          1485:        of just checking for TME_RECODE_OPCODE_GUEST. 
        !          1486:        Fixed a bug in the v9 32-bit shifts where we put the extension source
        !          1487:        size in the immediate field, instead of the second source operand
        !          1488:        field. 
        !          1489:        Reused the old TME_SPARC_RECODE_INSN_STORE support for generating an

        !          1493: 
        !          1494:        * ic/sparc/sparc-fpu-auto.sh (_tme_sparc_fpu_fcc_${precision}): Added
        !          1495:        support for the additional fccN on sparc64. 
        !          1496:        (tme_sparc_fpu_fpop[12]): Added support for encoded floating-point
        !          1497:        register numbers, recode verification, FMOV*cc, FxTO*, F*TOx, FNEGd,
        !          1498:        FABSd.  Now dirty any destination register. 
        !          1499: 
        !          1500:        * ic/sparc/sparc-impl.h: Replaced all of the old TME_SPARC_TRAP_
        !          1501:        macros with architecture-specific trap macros, whose values now
        !          1502:        include priority and other flags.  For those trap names that are
        !          1503:        common across architectures, a new TME_SPARC_TRAP() macro can be used
        !          1504:        to expand to the right value for the current architecture.  All users
        !          1505:        changed.  For sparc64, added the FPRS, TSTATE, WSTATE, VER, XCC, and
        !          1506:        VIS GSR fields, and added more PSTATE fields.  Added the sparc VIS
        !          1507:        ASIs. 
        !          1508:        Added macros for the SPARC integer conditions.  Added
        !          1509:        TME_SPARC_MODE_OFF and TME_SPARC_TL_MAX.  Added a set of macros for
        !          1510:        updating the register window offsets for a new CWP, that update
        !          1511:        separate offsets for the output, local, and input registers, and also
        !          1512:        the recode register window offsets.  This simplifies
        !          1513:        TME_SPARC_REG_INDEX.  Now that there are only flat DTLB and ITLB
        !          1514:        arrays, added a TME_SPARC_TLB_HASH() to hash an address into an array. 
        !          1515:        TME_SPARC_DTLB_ENTRY() and TME_SPARC_ITLB_ENTRY() now take one of
        !          1516:        these hashes, instead of an address.  The slow load and store
        !          1517:        functions, and any function that supports a slow load or store, now
        !          1518:        take an expanded set of information about the access. 
        !          1519:        Added macros for defining masks of load/store faults and memory
        !          1520:        features. 
        !          1521:        Now define TME_SPARC_FPU_FPREG_NUMBER_UNDEF, TME_SPARC_FPU_DIRTY(),
        !          1522:        and TME_SPARC_FPU_IS_DISABLED().  Fixed TME_SPARC_FORMAT3_RD_ODD() to
        !          1523:        take the register set name for the architecture. 
        !          1524:        Added TME_SPARC_INSN_FPU_ENABLED, which TME_SPARC_INSN_FPU now uses. 
        !          1525:        Removed TME_SPARC_INSN_FPU_STORE. 
        !          1526:        [TME_HAVE_RECODE]: Now define macros for sparc recode. 
        !          1527:        (tme_sparc_log_start): Fixed sparc64 support.  Now define macros for
        !          1528:        fixing PROM delay factors.  Now define TME_SPARC_MEMORY_FLAGS() and
        !          1529:        _TME_SPARC_MEMORY_FLAGS().  Removed TME_SPARC_ASI_DATA(). 
        !          1530:        Now typedef _tme_sparc64_format3 and _tme_sparc_ls_asi_handler.  Added
        !          1531:        struct tme_sparc_ls. 
        !          1532:        [TME_HAVE_RECODE]: Added struct tme_sparc_recode_cacheable.  In struct
        !          1533:        tme_sparc, added the cycles scaling, replaced the single CWP offset
        !          1534:        with individual offsets for the global, output, local, and input
        !          1535:        registers.  Added members for sparc64.  Expanded the
        !          1536:        implementation-dependent data and functions, especially for the new
        !          1537:        load/store architecture.  Retyped the instruction burst counters as
        !          1538:        tme_uint32_t, since recode requires that.  Replaced the old TLB entry
        !          1539:        set pointers with a single sparc TLB entry array and a complementary
        !          1540:        array of tokens or recode TLB entries.  Added per-ASI information, and
        !          1541:        members for memory context.  Added members for the new bus external
        !          1542:        interface.  Changed the memory buffer to be a union of all of the
        !          1543:        integral types.  Expanded the number of FPU registers and added the
        !          1544:        sparc64 XFSR.  Added the VIS state.  Fixed a bug where the sparc64
        !          1545:        idle PC was a tme_uint32_t.  Under [TME_HAVE_RECODE], added all of the
        !          1546:        state needed for sparc recode.  Added more statistics.  Changed many
        !          1547:        prototypes, generally for the new load/store architecture, trap
        !          1548:        changes, sparc recode verification, and sparc64 support. 
        !          1549:

        !          1554:        (tme_sparc${arch}_vis_ls_asi_pst): Fixed some comments about trap
        !          1555:        handling, and check that our caller checked that the FPU is enabled
        !          1556:        and not in exception_pending mode. 
        !          1557:        (tme_sparc${arch}_vis_ls_asi_fl): Fixed some comments about trap

        !          1568:        supported.  Define _TME_LOG_ALIGN_ANY(). 
        !          1569:        Typedef tme_log_arg_code_t. 
        !          1570:        (LOG_PRF_LOCALS): Added support for two 'l' flags, and for long long

                   2753: 
                   2754:        * host/bsd/bsd-bpf.c (_tme_bsd_bpf_read): Fixed a bug where we would
                   2755:        drop packets or pass garbage packets because we weren't using
                   2756:        BPF_WORDALIGN() to determine the offset of the next packet.  Added
                   2757:        code to try to detect and strip off any CRC accidentally passed up
                   2758:        through BPF from a host network device driver. 
                   2759: 
                   2760:        * ic/m68k/m68010.c (_tme_m68010_rte): A zero returned by
                   2761:        tme_m68k_sequence_fill() or tme_m68k_insn_buffer_fill() also means a

                   2771: 
                   2772:          Although I hate doing this, many changes to convert the m68k
                   2773:          emulation to the new TLB and memory discipline.  This has mainly
                   2774:          affected fast instruction fetching and memory access.  Fast
                   2775:          instruction fetches now happen directly into the instruction buffer,
                   2776:          with some optimizations to lessen the penalty for that.  Fast
                   2777:          fetches are now kept entirely out of the transfer accounting, and
                   2778:          the functions that empty and fill the instruction buffer from an
                   2779:          exception frame are also simpler now. 
                   2780:          All memory access functions now busy and unbusy a TLB entry and use
                   2781:          the generic memory access functions when doing fast transfers. 
                   2782:          The tme_m68k_rmw_start() and tme_m68k_rmw_finish() are completely
                   2783:          changed for the new TLB discipline.  All of the atomic instructions
                   2784:          are also completely changed.  All callouts are now wrapped in
                   2785:          tme_m68k_callout_unlock() and tme_m68k_callout_relock(), which will
                   2786:          unbusy and rebusy any instruction TLB entry for the fast executor,
                   2787:          and poison the fast executor if that TLB entry is now invalid.

                   2804: 
                   2805:        * machine/sun/sun-bwtwo.c: Removed much code, which became the new
                   2806:        generic Sun framebuffer code.  The remaining bwtwo code now uses this
                   2807:        generic support.  Added support for the SBus bwtwo.

                   2812:        (_tme_suncg2_mode_change): Don't try to make any sense of the case
                   2813:        where the pixel colors don't select any bitmap.  In this case, or when
                   2814:        multiple bitmaps seem to be selected, just display the pixmap. 
                   2815:

                   2818:        equal to zero.  This would happen on 64-bit big-endian systems, due to
                   2819:        their particular struct tme_ic register layout. 
                   2820: 
                   2821:        * machine/sun2/sun2-mmu.c (_tme_sun2_mmu_reset): Now busy and
                   2822:        unbusy-fill the reset TLBs, so they are marked valid. 
                   2823: 
                   2824:        * machine/sun4/sun4-impl.h: Added a prototype for _tme_sun4_reset().

                   2852:        * generic/bus.c (tme_bus_tlb_map): Fixed a word-size bug, where the
                   2853:        address offset was kept as a tme_bus_addr_t.  Since this offset can be
                   2854:        negative, and it's used in pointer arithmetic, it has to be a signed

                   2877:        aligned to four, since it is often used as a register pair, and the
                   2878:        ldd/std functions expect the first register of a pair (and later, some

                   3213:        Now fetch all instructions with tme_memory_bus_read32(), which gives
                   3214:        all needed behavior (when threads are cooperative,
                   3215:        tme_memory_atomic_read32 means a function call).  Now log call
                   3216:        instructions, which makes reconstructing code flow possible.

                   3232:        act as call or return instructions, which makes reconstructing code
                   3233:        flow possible.  In the slow load/store functions, use the ASI mask for
                   3234:        instructions if the instruction flag is specified, and allow the
                   3235:        CPU-specific bus fault handler to cancel a fault.

                   3313:        fixed a bug where we would pass in NULL for __LINE__, instead of zero. 
                   3314:        Added a prototype for tme_sjlj_cond_sleep_yield(), and the
                   3315:        tme_cond_sleep_yield() macro.  Removed the old atomic memory access

                   3320:        TME_BUS_CONNECTION_INT_FLAG_CONTROLLER.  Now define struct
                   3321:        tme_bus_slot.  In struct tme_bus, keep a list of struct tme_bus_slot,
                   3322:        and track up to one bus connection that is the "controller" of the

                   3329:        * tme/generic/ic.h: Quadrupled the value of TME_IC_REGS_SIZE, to
                   3330:        support the SPARC emulations and their large register sets.  In struct
                   3331:        tme_ic, fixed the definitions for the 64-bit register members, to
                   3332:        divide the TME_IC_REGS_SIZE by eight instead of sixteen. 
                   3333:

                   3342:        tme_sun_mmu_info, added tme_sun_mmu_info_topindex_bits, for describing
                   3343:        either the number of top address bits for region, or for the address
                   3344:        hole. 
                   3345:

                   3370: 
                   3371:          Changed how atomic values are handled.  Removed the TME_ATOMIC_ set
                   3372:          of macros, which may or may not use a rwlock to serialize access to
                   3373:          a value, and added the tme_memory_atomic_ set of macros, which
                   3374:          always requires an rwlock argument. 
                   3375:          This tme_memory_atomic_ set of macros also takes a compile-time
                   3376:          minimum alignment hint, covers a wide range of math operations, and
                   3377:          is guaranteed to work atomically for any access, no matter what the
                   3378:          actual alignment. 
                   3379:          Added the tme_memory_bus_ set of macros, which work just like the
                   3380:          tme_memory_atomic_ macros but only within a certain bus size - i.e.,
                   3381:          if a 32-bit bus size is specified, and an access crosses one
                   3382:          32-bit-aligned address boundary, the access will be split into two
                   3383:          atomic accesses. 
                   3384:          The tme_memory_atomic_ and tme_memory_bus_ macros should better
                   3385:          enable emulation on a non-cooperative threading host someday.  Added
                   3386:          the tme_memory_ set of macros, which don't access memory atomically
                   3387:          but still take the same compile-time minimum-alignment hint and are
                   3388:          guaranteed to work for any actual alignment.  This has caused
                   3389:          significant fallout in all TLB handling, since the first and last
                   3390:          address fields in a TLB were previously TME_ATOMICs, and TLBs were
                   3391:          invalidated by atomically updating these first to be greater than
                   3392:          last. 
                   3393:          This method would not have worked in a non-cooperative threading
                   3394:          host.  First, it was impossible to update both first and last
                   3395:          address fields simultaneously, and second, it was impossible to know
                   3396:          if anyone was using, or had committed to using, the TLB while you
                   3397:          were invalidating it.  Without knowing that the TLB can't be used
                   3398:          after invalidation, the invalidator can't continue and make other
                   3399:          changes that would give incorrect behavior if the TLB *is* actually
                   3400:          used later. 
                   3401:          So, TLBs have a new discipline.  They have "busy" and "invalid"
                   3402:          atomic flags.  Before a TLB entry is used, its busy flag is marked
                   3403:          true, and its invalid flag is checked.  If the invalid flag is true,
                   3404:          the TLB is unbusied and prepared for filling (see
                   3405:          tme_bus_tlb_unbusy_fill() and tme_bus_tlb_invalidate() for how they
                   3406:          synchronize and avoid interesting races), otherwise the TLB entry is
                   3407:          valid and won't be invalidated until its busy flag is set to false. 
                   3408:          To make this truly thread-safe, someday all slow bus cycle handlers
                   3409:          will have to take a TLB entry somehow, so they can correctly busy
                   3410:          the TLB entry before making the access.

                   3518:        define little-endian conversion functions on big-endian hosts. 
                   3519:

                   3696:        * tme/generic/bus.h: Added a prototype for tme_bus_cycle_xfer_reg(). 
                   3697: 
                   3698:        * tme/generic/fb.h: Added macros for the different image classes,
                   3699:        mapping types, and default subfield masks.  Also added macros for the
                   3700:        "any" subfield mask, and for the mask of the maximum index value. 
                   3701:        Expanded struct tme_fb_connection and struct tme_fb_xlat to include
                   3702:        image class, subfield masks, and mapping information.  Added
                   3703:        prototypes for tme_fb_xlat_colors_get() and tme_fb_xlat_colors_set().

                   3713:        call tme_m68k_opcodes_init_m68010() to initialize the opcode table. 
                   3714:

                   3718:        * ic/m68k/m6888x.c (tme_m68k_fbcc): Fixed a bug in calculating the
                   3719:        target PC; the displacement is always added to the original PC plus
                   3720:        two.  Now always take a 32-bit displacement as a proper operand. 
                   3721: 
                   3722:        * ic/m68k/m68k-execute.c: Simplified how instructions are decoded and
                   3723:        executed.  Now, the first 16-bit instruction word is used to directly
                   3724:        index an array of 32-bit integers, each of which gives the
                   3725:        instruction's function number, the function's arguments, immediate
                   3726:        fetching and EA calculation information, and a single
                   3727:        special-operation escape bit.  Only two types of immediate fetches are
                   3728:        supported: a 16-bit fetch, sign-extended to 32 bits, and a 32-bit
                   3729:        fetch.  All of this speeds things up dramatically. 
                   3730:        [_TME_M68K_STATS]: Keep statistics on executed instructions. 
                   3731: 
                   3732:        * ic/m68k/m68k-impl.h: Removed TME_M68K_SIZE_SUBMAP_X,
                   3733:        TME_M68K_SIZE_16U8, TME_M68K_SIZE_16S32, TME_M68K_OPNUM_SUBMAP_X,
                   3734:        TME_M68K_OPNUM_UNDEF, and the list of special opcodes, all of which
                   3735:        were used only in the old opcode maps. 
                   3736:        Added macros for the decoded instruction parameters in the new opcode
                   3737:        maps. 
                   3738:        Removed the data structures used by the old opcode maps.  The EA
                   3739:        register is now a proper IC register.  Added statistics to struct
                   3740:        tme_m68k.  Removed the declarations of the small immediate arrays. 
                   3741:        The small immediates are now proper IC registers.  Added declarations
                   3742:        of the different CPUs' opcode maps and their initialization functions,
                   3743:        and the instruction function array.  Added declarations for
                   3744:        tme_m68k_bccl(), tme_m68k_bsrl(), tme_m68k_divl() and tme_m68k_mull(). 
                   3745: 
                   3746:        * ic/m68k/m68k-insns.c (tme_m68k_bccl):
                   3747:        (tme_m68k_bsrl):
                   3748:        (tme_m68k_link):
                   3749:        (tme_m68k_rtd): Now that the opcode map supports 16-bit immediates
                   3750:        sign-extended to 32 bits, always take a proper 32-bit operand. 
                   3751: 
                   3752:        * ic/m68k/m68k-iset.txt: Now that the opcode map supports 16-bit
                   3753:        immediates sign-extended to 32 bits again, make rtd and the 16-bit
                   3754:        versions of link, bsr, bcc, and fbcc take this kind of immediate. 
                   3755: 
                   3756:        * ic/m68k/m68k-misc.c (tme_m68k_exception): Now log a message when a
                   3757:        double fault causes a processor halt. 
                   3758: 
                   3759:        * ic/m68k/m68k-opmap-make.pl: The initial rewrite of the opcode map
                   3760:        generation resulted in an enormous opcode map source file, and,
                   3761:        because the instruction function pointers were in the map entries
                   3762:        directly, an opcode map array that wasn't 64-bit friendly. 
                   3763:        Now, the instruction function pointers are in a small separate array
                   3764:        which is indexed by eight bits in the 32-bit opcode parameter
                   3765:        information, which is all that remains in the opcode map.  To make
                   3766:        room for these eight bits, the first EA mode and reg fields are not
                   3767:        stored (and are instead are swapped in by the instruction executer
                   3768:        after the instruction function has been fetched), and the special
                   3769:        operation field has been reduced to a single bit.  To shrink the
                   3770:        opcode map sources, we take advantage of the fact that each of the
                   3771:        1024 aligned sets of 64 opcodes (a "root") uses one of a small number
                   3772:        of patterns to initialize itself (for m68000 through m68020, there are
                   3773:        only 37 such patterns), and we generate a function to initialize the
                   3774:        parameters in that pattern.  Also, each CPU uses the previous CPU's
                   3775:        opcode initialization function to initialize the bulk of its opcode
                   3776:        map, making changes only as needed. 
                   3777:        All of this has reduced the size of the opcode map source file
                   3778:        dramatically. 
                   3779:        Also, support for 16-bit immediates, sign-extended to 32 bits, has
                   3780:        been added again.

                   3785:        sign-extended to 32-bits in a fixed immediate register. 
                   3786:

                   3896: 
                   3897:        * machine/sun2/SUN2-MULTIBUS: Make the bpf attachment for ie0 delay
                   3898:        packets slightly.  This works around a sleep/wakeup race condition in
                   3899:        the NetBSD kernel RARP code. 
                   3900:        Changed the type of the bwtwo from obmem to multibus, since the bwtwo

                   3905:        Increased the size of the VME bus to the full 4GB.  Commented out the
                   3906:        sc0 attachment, in favor of the new si0 attachment. 
                   3907:        To support stock NetBSD 1.6*, make the Emulex tape respond to INQUIRY

                   3931:        happen, then taking one or more SCSI actions. 
                   3932:        (_tme_scsi_bus_callout): Now call out the events triggered and actions

                   3937:        now support for half and full SCSI bus arbitration, and reselection.

                   3952:        Now identify as a SCSI-1 device, and be sure not to return more data
                   3953:        than the initiator requested. 
                   3954:

                   3956:        Added some missing parentheses to _TME_FIELD_DEPOSIT().  Fixed a bug
                   3957:        in the definition of the tme_value64_uint32s[] member of union

                   3965: 
                   3966:        * tme/generic/scsi.h: Now define TME_SCSI_ID_SELECTED() and
                   3967:        TME_SCSI_ID_RESELECTED(), to determine if an ID is being selected or
                   3968:        reselected.  Replaced the idea of a SCSI sequence with the much
                   3969:        simpler idea of a bus agent waiting for one or more SCSI events to

                   3993:        Now check for limits.h and float.h.  Check for volatile, float,
                   3994:        double, and long double, and the signal handler type. 
                   3995:        Added ieee754 and ncr5380 to the list of sun3 ICs.  When using gcc,

                   4036:        and only on stage C for a 32-bit fetch.  This was supposed to be the

                   4247:        * ic/m68k/m68010.c: Removed GROUPn_ from the TME_M68K_EXCEPTION_ macro
                   4248:        names, since those group numbers applied to only the 68000 and 68010. 
                   4249:        Also added the new TME_M68K_VECTOR_ macros. 
                   4250: 
                   4251:        * ic/m68k/m68k-execute.c (_TME_M68K_EXECUTE_NAME): Fixed problems with
                   4252:        the way that tracing is handled, to enable support for 68020 tracing
                   4253:        and its new trace exception frame format.  Fixed a bug in the code
                   4254:        that detects a 32-bit branch.  Fixed a bug in decoding the divul and
                   4255:        mulul extension words.  Added missing declarations for some variables
                   4256:        used in 68020 effective address calculation. 
                   4257: 
                   4258:        * ic/m68k/m68k-impl.h: Replaced TME_M68K_FLAG_T with TME_M68K_FLAG_T0
                   4259:        and TME_M68K_FLAG_T1, and use them wherever possible.  Removed the
                   4260:        GROUPn_ from the TME_M68K_EXCEPTION_ macros, since the original group
                   4261:        numbers were specific to the 68000 and 68010.  Added more exception
                   4262:        frame format identifier macros.  Added new macros for the exception
                   4263:        vectors. 
                   4264:        (TME_M68K_INSN_BRANCH):
                   4265:        (TME_M68K_INSN_CHANGE_SR): Improved tracing support. 
                   4266: 
                   4267:        * ic/m68k/m68k-insns-auto.sh: The old asr expansion (which was the
                   4268:        same as the lsr expansion, but with a signed operand and result) had
                   4269:        bugs and also required that right shifts of a signed operand be
                   4270:        arithmetic.  Added a new expansion that fixes these problems. 
                   4271:        Removed the _GROUPn from the TME_M68K_EXCEPTION_ macro names, since
                   4272:        the group numbers were specific to the 68000 and 68010.  Also added
                   4273:        the new TME_M68K_VECTOR_ macros. 
                   4274:        In the bus-cycle functions, recognize the
                   4275:        TME_BUS_CYCLE_SYNCHRONOUS_EVENT pseudo-error, and make it force the
                   4276:        executer to check external events before executing the next
                   4277:        instruction. 
                   4278: 
                   4279:        * ic/m68k/m68k-insns.c: Removed the _GROUPn from the
                   4280:        TME_M68K_EXCEPTION_ macro names, since the group numbers were specific
                   4281:        to the 68000 and 68010.  Also added the new TME_M68K_VECTOR_ macros. 
                   4282:        Where applicable, store the current PC as the last PC before setting
                   4283:        the next PC as the current PC.  This supports format 2 exception
                   4284:        frames, which stack the address of the instruction that caused the
                   4285:        exception. 
                   4286:        (tme_m68k_movec): Added support for the 68020 control registers. 
                   4287: 
                   4288:        * ic/m68k/m68k-misc-auto.sh: Create registers for the next program
                   4289:        counter, the 68020 cacr and caar, and the always-zero register. 
                   4290: 
                   4291:        * ic/m68k/m68k-misc.c: Removed the _GROUPn from the
                   4292:        TME_M68K_EXCEPTION_ macro names, since the group numbers were specific
                   4293:        to the 68000 and 68010.  Also added the new TME_M68K_VECTOR_ macros. 
                   4294:        (_tme_m68k_bus_interrupt):
                   4295:        (tme_m68k_external_check): Implement a system that prevents NMI from
                   4296:        being repeatedly accepted.  If the interrupt priority mask is already
                   4297:        seven, only accept an NMI on a transition from deasserted to asserted. 
                   4298:        (tme_m68k_new): Now set the mask of T bits used by the processor. 
                   4299:        (tme_m68k_do_reset): Now clear the E and F bits in the 68020 cacr. 
                   4300:        Fixed a bug where we loaded the initial SSP and PC from supervisor
                   4301:        data space instead of the correct supervisor program space. 
                   4302:        (tme_m68k_change_sr): Only recognize the M bit on a 68020 or greater,
                   4303:        and fixed bugs in the selection of the correct stack pointer control
                   4304:        register. 
                   4305:        (tme_m68k_exception_process): Renamed to tme_m68000_exception_process,
                   4306:        since the grouping and priority it implements are specific to the
                   4307:        68000 and 68010. 
                   4308:        (tme_m68020_exception_process): Added. 
                   4309:        (tme_m68k_bitfield_offset): Simplified the bitfield byte offset
                   4310:        calculation for negative bit offsets. 
                   4311:        (tme_m68k_bitfield_width): Don't bother masking a bitfield width that
                   4312:        was encoded in the instruction; it can't be greater than 31. 
                   4313:        (_tme_m68k_bitfield_read): If the bitfield is in memory, note that the
                   4314:        current instruction can fault.  Fixed bugs where we assumed that
                   4315:        TME_BIT(32) is zero mod 2^32, when it may be 1 because of shift
                   4316:        limiting, which would cause us to fail to mask and/or sign-extend a
                   4317:        32-bit bitfield value correctly. 
                   4318:        (tme_m68k_bitfield_write_unsigned): Fixed a bug where we wouldn't mask
                   4319:        the value we were given before setting the flags.  Fixed bugs where we
                   4320:        assumed that TME_BIT(32) is zero mod 2^32, when it may be 1 because of
                   4321:        shift limiting.  If the bitfield is in memory, note that the current
                   4322:        instruction can fault. 
                   4323: 
                   4324:        * ic/m68k/m68k-verify.c (tme_m68k_verify_mem_any): Fixed a bug where
                   4325:        we wouldn't properly verify transfers of endianless data. 
                   4326:        (tme_m68k_verify_init): Now set up a full 32-bit address space. 
                   4327:        (_tme_m68k_verify_end): Store %a7 back in its proper stack pointer
                   4328:        control register, so we can verify changes to the control registers. 
                   4329:        Ignore extra verifier memory reads on bitfield instructions; the
                   4330:        verifier bitfield implementation often reads addresses not covered by
                   4331:        the bitfield. 
                   4332: 
                   4333: Mon May 17 11:57:01 2004  Matthew Fredette  <[email protected]>
                   4334: 
                   4335:        * host/bsd/bsd-bpf.c: Added support for the "delay" option, which
                   4336:        delays all incoming packets for a user-specified number of
                   4337:        microseconds. 
                   4338:        (_tme_bsd_bpf_read): Fixed a bug where a TME_ETHERNET_READ_PEEK read
                   4339:        would discard the read packet. 
                   4340: 
                   4341: Fri May 14 00:56:19 2004  Matthew Fredette  <[email protected]>
                   4342: 
                   4343:        * host/bsd/bsd-bpf.c: Removed the unused tme_bsd_bpf_cond_writer
                   4344:        structure member. 
                   4345:        (tme_host_bsd,bpf): Fixed a bug where we weren't initializing the
                   4346:        tme_bsd_bpf_conf_reader condition. 
                   4347: 
                   4348: Tue May 11 12:03:36 2004  Matthew Fredette  <[email protected]>
                   4349: 
                   4350:        * ic/i825x6.c: Added some logging. 
                   4351:        (_tme_i825x6_callout_ru): Don't set the B bit in RFD status fields. 
                   4352: 
                   4353:        * libtme/misc.c (_tme_misc_number_parse): Some changes to silence gcc
                   4354:        -Wuninitialized. 
                   4355:

                   4357: 
                   4358:        * bus/multibus/sun-mie.c:
                   4359:        * ic/i825x6.c:
                   4360:        * ic/i825x6reg.h:
                   4361:        * tme/ic/i825x6.h: Added. 
                   4362: 
                   4363:        * machine/sun2/SUN2-MULTIBUS: Added commands to create ie0. 
                   4364: 
                   4365: Fri Apr 30 12:11:36 2004  Matthew Fredette  <[email protected]>
                   4366:

                   4368:          ic/am9513.c ic/z8530.c ic/m68k/m68k-insns.c ic/m68k/m68k-misc.c
                   4369:          machine/sun2/sun2-mainbus.c tme/generic/bus.h:
                   4370: 
                   4371:          Reworked bus signals in several ways: Added the notion of the bus
                   4372:          signals set.  Every bus should support multiple device-specific bus
                   4373:          signals sets, added by elements connecting to the bus.  This enables
                   4374:          elements to pass these device-specific bus signals to each other. 
                   4375:          Now bus signals are only specified as either asserted or negated,
                   4376:          and devices almost never signal edges.  For devices that only drive
                   4377:          signals either high or low, you can exclusive-or
                   4378:          TME_BUS_SIGNAL_LEVEL_ASSERTED with either TME_BUS_SIGNAL_LEVEL_HIGH
                   4379:          or TME_BUS_SIGNAL_LEVEL_LOW as appropriate, and provide that to the
                   4380:          device such that the device only needs to exclusive-or that with the
                   4381:          signal level to get the right asserted or negated level.  Also
                   4382:          expanded the number of generic bits in a signal value, and improved
                   4383:          the set of macros used to compose and decompose signal values. 
                   4384: 
                   4385:        * bus/multibus/sun-sc.c generic/bus.c ic/m68k/m68k-misc.c
                   4386:          machine/sun/sun-mmu.c tme/generic/bus.h:
                   4387: 
                   4388:          Made changes to the TLB protocol, to better support reentrant
                   4389:          devices.  Now, a TLB entry passed to a fill function is expected to
                   4390:          be local on the stack, and it "reserves" the real, backing TLB entry
                   4391:          in the device's state.  This prevents the case where a device tries
                   4392:          to fill the same backing TLB entry at the same time in two or more
                   4393:          threads.  TLB fill functions for devices that need to invalidate
                   4394:          outstanding TLBs always invalidate the backing TLB entry.  After a
                   4395:          TLB fill has finished, the caller checks its reservation on the
                   4396:          real, backing TLB, and copies the local TLB back if the reservation
                   4397:          has not been broken.  Devices that want to use a TLB entry
                   4398:          immediately after the fill function returns must use the local TLB,
                   4399:          since it cannot have been invalidated yet.  Also made fixes to TLB
                   4400:          entry users that avoid rereading fields that are destroyed by
                   4401:          invalidation, after the device has committed to using the TLB entry,
                   4402:          since invalidation can happen at any time.  Also made the TLB
                   4403:          tme_bus_tlb_emulator_off_read member const. 
                   4404:

                   4407:        * tme/generic/bus-device.h: Added generic bus-device support for real
                   4408:        bus interfaces and bus-mastering.

                   4419: 
                   4420:        * tme/common.h: Added the TME_X_VERSION versioning macros.  Simplified

                   4422: 
                   4423:        * tme/generic/ethernet.h: Now define TME_ETHERNET_LENGTH_SIZE and

                   4826:

                   4844:        * generic/bus-el.c: Fixed a comment. 
                   4845:

                   4851:        * ic/mm58167.c: Fixed many significant problems with this emulation,
                   4852:        most notably that the size of the chip was not calculated correctly at
                   4853:        all.  We now report with microsecond resolution, since SunOS's probe
                   4854:        routine requires this. 
                   4855: 
                   4856:        * ic/z8530.c (_tme_z8530_intack): Simplified and fixed bugs in how
                   4857:        variable interrupt vectors are computed.  For now, since there's no
                   4858:        emulation of the IEI pin, we just behave as if it's always tied low,
                   4859:        so we never put any vector on the bus during a hard interrupt
                   4860:        acknowledge. 
                   4861:        (_tme_z8530_bus_cycle): Now ignore all WR0 CRC reset commands.  Now
                   4862:        support the WR0 transmitter reset command.  Now support reads of RR10
                   4863:        and RR14. 
                   4864: 
                   4865:        * ic/m68k/m68k-insns-auto.sh: The movem instructions cannot fault when
                   4866:        the register mask is zero.  Now that we generally have a 64-bit type
                   4867:        available, fixed various bugs in the 64-bit multiply and divide
                   4868:        instructions. 
                   4869: 
                   4870:        * ic/m68k/m68k-insns.c (tme_m68k_movec): Now appropriately mask values
                   4871:        loaded into control registers.  movec only has a long version, and
                   4872:        SunOS on the Sun-2 doesn't necessarily clear the remainder of the data
                   4873:        register it uses to load %sfc and %dfc. 
                   4874: 
                   4875:        * ic/m68k/m68k-misc.c (tme_m68k_exception_process_start): Fixed a bug
                   4876:        where the T bits weren't cleared.  This bug was found by SunOS on the
                   4877:        sun2, which starts at least init in usermode with tracing enabled. 
                   4878: 
                   4879:        * ic/m68k/m68k-verify.c (tme_m68k_verify_init): Now assume that the
                   4880:        CPU generates 28-bit addresses.  SunOS 3 on the Sun-2 does this. 
                   4881: 
                   4882:        * machine/sun/tme-sun-idprom.pl: Added support for the obscure
                   4883:        Roadrunner-MB1. 
                   4884: 
                   4885:        * machine/sun2/sun2-bwtwo.c: Fixed various comments. 
                   4886:        Because SunOS's probe routine fails otherwise, added support for the
                   4887:        entire 2KB page starting at the CSR to appear undecoded, i.e., to look
                   4888:        like the CSR repeated 1024 times. 
                   4889: 
                   4890:        * machine/sun2/sun2-impl.h: Now define TME_SUN2_DVMA_SIZE_MBMEM and
                   4891:        TME_SUN2_DVMA_SIZE_VME. 
                   4892:        Now make struct tme_sun2_bus_connection public, since the bus DVMA TLB
                   4893:        filler needs to know which bus it's filling for. 
                   4894: 
                   4895:        * machine/sun2/sun2-mainbus.c (_tme_sun2_connections_new): When making
                   4896:        the connections for the mbmem or vme buses, be sure to set the last
                   4897:        address that we decode on the bus, for DVMA purposes. 
                   4898: 
                   4899:        * machine/sun2/sun2-mmu.c (_tme_sun2_bus_tlb_fill): Fixed many bugs
                   4900:        involving filling TLB entries for bus's DVMA regions. 
                   4901:        (_tme_sun2_mmu_pte_set): Added a missing protection. 
                   4902: 
                   4903:        * tme/common.h: Added some crude support for 64-bit math, even for
                   4904:        compilers that offer no 64-bit type at all. 
                   4905: 
                   4906:        * tme/connection.h: Now define TME_CONNECTION_SCSI and
                   4907:        TME_CONNECTION_DISK. 
                   4908: 
                   4909:        * tme/generic/Makefile.am: Added more headers. 
                   4910: 
                   4911:        * tme/generic/bus-device.h: Corrected a comment. 
                   4912: 
                   4913:        * tme/generic/ic.h: Corrected the 64-bit support. 
                   4914: 
                   4915:        * tmesh/tmesh-cmds.c (_tmesh_command_log): Added. 
                   4916: 
                   4917:        * tmesh/tmesh-impl.h: Now define TMESH_COMMAND_LOG.

                   4919:        * tmesh/tmesh-input.y: Added support for parsing the `log' command.
