1.1 ! root 1: Sun May 18 00:07:59 2003 Matthew Fredette <[email protected]> ! 2: ! 3: * Release 0.0 out. ! 4: ! 5: * configure.in: Changed the version number to 0.0; this is very alpha. ! 6: There are now fewer include directories under tme/; many ! 7: unnecessary headers that belonged to modules were removed. ! 8: ! 9: * bus/multibus/3c400.c: No longer include <tme/bus/multibus/3c400.h>. ! 10: * bus/multibus/Makefile.am: Added library and module versioning. ! 11: * generic/Makefile.am: Added library and module versioning. ! 12: * host/bsd/Makefile.am: Added library and module versioning. ! 13: * host/bsd/bsd-bpf.c: Now include "bsd-impl.h" instead of <tme/host/bsd.h>. ! 14: * host/bsd/bsd-if.c: Now include "bsd-impl.h" instead of <tme/host/bsd.h>. ! 15: * host/bsd/bsd-impl.h: Added. ! 16: * host/posix/Makefile.am: Added library and module versioning. ! 17: * ic/Makefile.am: Added library and module versioning. ! 18: * ic/m68k/Makefile.am: Added library and module versioning. ! 19: * libtme/Makefile.am: Added library and module versioning. ! 20: * machine/sun/Makefile.am: Added library and module versioning. ! 21: * machine/sun/tme-sun-idprom.pl: Added. ! 22: * machine/sun2/Makefile.am: Added library and module versioning. ! 23: * machine/sun2/SUN2-MULTIBUS: Changed the extension on the PROM and IDPROM ! 24: files from .dat to .bin. ! 25: ! 26: * machine/sun2/SUN2-MULTIBUS: Changed the name of the PROM filename to match the documentation. ! 27: * tme/Makefile.am: Removed the host and bus include directories; they don't exist anymore. ! 28: * tmesh/Makefile.am: Added library and module versioning. ! 29: ! 30: Sat May 17 20:16:06 2003 Matthew Fredette <[email protected]> ! 31: ! 32: * acinclude.m4: Added an RCS Id and a short comment. ! 33: * configure.in: Added an RCS Id, the copyright, and license. ! 34: Do a real path search for perl. ! 35: ! 36: * libtme/log-prf.c: Changes to silence gcc -Wuninitialized. ! 37: * libtme/module.c: Changes to silence gcc -Wuninitialized. ! 38: * machine/sun2/sun2-mainbus.c: Changes to silence gcc -Wuninitialized. ! 39: ! 40: Fri May 16 21:48:16 2003 Matthew Fredette <[email protected]> ! 41: ! 42: * By far, this is the worst bulk commit I've ever done. ! 43: Many changes to simplify the element interface as much ! 44: as possible, to do modules better, and to do logging ! 45: better. Fixed a small number of actual bugs. Also ! 46: converted to modern autoconf and automake, because ! 47: the module support requires modern libtool. ! 48: Also added the main libtme, libtmesh, and tmesh itself. ! 49: ! 50: Fri May 16 17:50:17 2003 Matthew Fredette <[email protected]> ! 51: ! 52: * acinclude.m4 (AC_CHECK_ALIGNOF): Now takes only a size, in bits, to check the ! 53: alignment for. Before, it used to take a string of the form intN_t, ! 54: which wouldn't work on systems that don't define an intN_t type. ! 55: When cross-compiling, assume the target requires alignment equal ! 56: to the size. Now use AC_DEFINE_UNQUOTED's third argument to ! 57: specify the config.h.in comment. ! 58: (AC_CHECK_SHIFTMAX): Added. ! 59: (AC_SYS_SOCKADDR_SA_LEN): Now use AC_DEFINE_UNQUOTED's third ! 60: argument to specify the config.h.in comment. ! 61: ! 62: Thu May 15 15:52:08 2003 Matthew Fredette <[email protected]> ! 63: ! 64: * ic/m68k/m68k-insns-auto.sh: Fixed bugs in the shift and rotate insns, where we might try to ! 65: shift by an amount greater than the maximum meaningful shift for ! 66: a given size. ! 67: ! 68: Sat May 10 13:46:02 2003 Matthew Fredette <[email protected]> ! 69: ! 70: * acinclude.m4 (AC_CHECK_ALIGNOF): Fixed a bug where this would stop on ! 71: the first misalignment, instead of continuing to find the ! 72: true minimum alignment. For example, this would have ! 73: found the minimum 32-bit alignment to be 4 instead of 2 ! 74: on a 68000 or 68010, stopping on the misaligned address 3. ! 75: ! 76: * configure.in: Some early distribution work. ! 77: * ic/Makefile.am: Some early distribution work. ! 78: * ic/m68k/Makefile.am: Some early distribution work. ! 79: * ic/m68k/m68k-insns-auto.sh: Fixed some bad macro and type name references. ! 80: * ic/m68k/m68k-insns-auto.sh: Handled the rename of the aligned and unaligned memory access ! 81: rwlocking macros, and use the new tme_memory_sequence_ rwlocking ! 82: macros. Generally made things a little easier to read, although ! 83: we do rely on the optimizer to do the right thing somewhat more. ! 84: ! 85: * ic/m68k/m68k-misc-auto.sh: Fixed some bad macro and type name references. ! 86: * ic/m68k/m68k-misc-auto.sh: Handled the rename of the aligned and unaligned memory access ! 87: rwlocking macros, and use the new tme_memory_sequence_ rwlocking ! 88: macros. Generally made things a little easier to read, although ! 89: we do rely on the optimizer to do the right thing somewhat more. ! 90: ! 91: * machine/Makefile.am: Some early distribution work. ! 92: * machine/sun2/Makefile.am: Some early distribution work. ! 93: * tme/Makefile.am: Some early distribution work. ! 94: * tme/threads.h: Renamed the memory-access locking functions to be ! 95: tme_memory_HOW_WHATlock, where HOW is aligned or ! 96: unaligned, and WHAT is rd or wr. ! 97: Now define the tme_memory_sequence_WHATlock macros, ! 98: used when doing a sequence of memory accesses that ! 99: must appear to be atomic. ! 100: Now define TME_SEQUENCE_ACCESS_NOT_COSTLIER as TRUE ! 101: if locking for a sequence and locking for an aligned ! 102: access have the same cost, else define it as FALSE. ! 103: ! 104: Sat May 10 00:31:32 2003 Matthew Fredette <[email protected]> ! 105: ! 106: * ic/m68k/m68k-insns-auto.sh: Overhauled the shift instructions to not use loops. ! 107: ! 108: Fri May 09 16:32:06 2003 Matthew Fredette <[email protected]> ! 109: ! 110: * ic/m68k/m68k-execute.c: As an optimization, now require the individual insn functions ! 111: to use TME_M68K_INSN_CANFAULT if they may fault, instead of ! 112: figuring out every time if an insn can fault or not. Check ! 113: that insn functions have set it if they need it, and left it ! 114: unset if they do not need it. ! 115: ! 116: * ic/m68k/m68k-execute.c: Made some changes to somewhat optimize certain ! 117: effective address calculations. ! 118: ! 119: * ic/m68k/m68k-impl.h: Now define TME_M68K_INSN_CANFAULT. ! 120: * ic/m68k/m68k-impl.h: Renumbered the TME_M68K_SIZE_ macros slightly to enable an ! 121: optimization on effective address predecrement/postincrement ! 122: calculation. Grew the memory transfer function arrays to ! 123: match. ! 124: Moved the generic IC data structure to the top of the m68k ! 125: structure, to enable register indexing to happen without ! 126: an offset. ! 127: Removed _tme_m68k_areg_increment, it's no longer needed. ! 128: ! 129: * ic/m68k/m68k-insns-auto.sh: Now use TME_M68K_INSN_CANFAULT where it's needed. Also ! 130: fixed some random restarting bugs in some insns. ! 131: ! 132: * ic/m68k/m68k-insns.c: Now use TME_M68K_INSN_CANFAULT where it's needed. Also ! 133: fixed some random restarting bugs in some insns. ! 134: ! 135: * ic/m68k/m68k-misc.c: Removed _tme_m68k_areg_increment, it's no longer needed. ! 136: Grew the memory transfer function arrays to match the ! 137: renumbering of the TME_M68K_SIZE_ macros, and added some ! 138: preprocessor error checking on those macros. ! 139: ! 140: Fri May 09 13:12:01 2003 Matthew Fredette <[email protected]> ! 141: ! 142: * bus/multibus/3c400.c: Bulk change to no longer require bus connections to have a ! 143: power-of-two width. This is largely a name change, renaming ! 144: address_mask to address_last, as nothing depended on the ! 145: address_mask being all-bits-one. ! 146: ! 147: * bus/multibus/3c400.c (_tme_3c400_callout): Make buffer status values have the minimum ! 148: Ethernet frame size. ! 149: ! 150: * generic/bus-device.c: Bulk change to no longer require bus connections to have a ! 151: power-of-two width. This is largely a name change, renaming ! 152: address_mask to address_last, as nothing depended on the ! 153: address_mask being all-bits-one. ! 154: ! 155: * generic/bus-el.c: Bulk change to no longer require bus connections to have a ! 156: power-of-two width. This is largely a name change, renaming ! 157: address_mask to address_last, as nothing depended on the ! 158: address_mask being all-bits-one. ! 159: ! 160: * generic/bus.c: Bulk change to no longer require bus connections to have a ! 161: power-of-two width. This is largely a name change, renaming ! 162: address_mask to address_last, as nothing depended on the ! 163: address_mask being all-bits-one. ! 164: ! 165: * host/posix/posix-memory.c: Bulk change to no longer require bus connections to have a ! 166: power-of-two width. This is largely a name change, renaming ! 167: address_mask to address_last, as nothing depended on the ! 168: address_mask being all-bits-one. ! 169: ! 170: * ic/am9513.c: Now include <stdio.h>, in case TME_AM9513_TRACK_INT_RATE is ! 171: defined. ! 172: ! 173: * ic/am9513.c: Bulk change to no longer require bus connections to have a ! 174: power-of-two width. This is largely a name change, renaming ! 175: address_mask to address_last, as nothing depended on the ! 176: address_mask being all-bits-one. ! 177: ! 178: * ic/am9513.c: Under TME_AM9513_TRACK_INT_RATE, periodically report the ! 179: interrupt rates achieved by the various timers. ! 180: ! 181: * ic/mm58167.c: Bulk change to no longer require bus connections to have a ! 182: power-of-two width.

This is largely a name change, renaming ! 188: address_mask to address_last, as nothing depended on the ! 189: address_mask being all-bits-one. ! 190: ! 191: * machine/sun2/sun2-mmu.c (_tme_sun2_m68k_tlb_fill): Because supervisor and user accesses ! 192: go through different context registers, TLBs are generally only ! 193: ever valid for the supervisor or the user, but not both. Fixed ! 194: a bug where a TLB for a user-visible page would be marked as good ! 195: for the supervisor even if the mapping isn't the same in the ! 196: system context. ! 197: ! 198: * tme/generic/bus-device.h: Bulk change to no longer require bus connections to have a ! 199: power-of-two width.

Under _TME_M68K_VERIFY, save and ! 238: restore the sequence unique identifier. ! 239: ! 240: * ic/m68k/m68k-verify.c: Many changes to support verifying instructions that ended ! 241: only after they were restarted because of one or more bus ! 242: faults. ! 243: ! 244: Thu May 08 13:35:43 2003 Matthew Fredette <[email protected]> ! 245: ! 246: * ic/m68k/m68k-execute.c: Replaced _TME_M68K_OPW_OK bits with new _TME_M68K_VERIFY bits. ! 247: * ic/m68k/m68k-impl.h: Replaced _TME_M68K_OPW_OK bits with new _TME_M68K_VERIFY bits. ! 248: * ic/m68k/m68k-insns-auto.sh: In all memory access functions, added calls to the verifier. ! 249: Fixed a bug in the divide routines, found by the verifier - ! 250: the N flag in set based on the final small quotient, not on ! 251: the big one. ! 252: ! 253: * ic/m68k/m68k-misc-auto.sh: Now define TME_M68K_IREG32_COUNT. ! 254: * ic/m68k/m68k-misc.c: Replaced _TME_M68K_OPW_OK bits with new _TME_M68K_VERIFY bits. ! 255: * ic/m68k/m68k-verify.c: Added. ! 256: ! 257: Wed May 07 02:35:17 2003 Matthew Fredette <[email protected]> ! 258: ! 259: * generic/bus-el.c (_tme_bus_connections_new): Store the final bus interrupt ! 260: signal number, not the raw ipl. ! 261: ! 262: * ic/z8530.c: Although I hate doing this, too many changes to go into ! 263: detail. Much work to support interrupt driven operation. ! 264: ! 265: * ic/z8530reg.h: Added definitions for RR3. ! 266: * ic/m68k/m68k-impl.h: Fixed a serious bug in the TME_M68K_FLAG_SR definition ! 267: that would zero part of the interrupt mask. !

384: * ic/m68k/m68010.c (_tme_m68010_rte): tme_m68k_rte_finish no longer touches the ! 385: sequence at all, so before calling it make sure the sequence ! 386: is exactly what it's supposed to be. ! 387: ! 388: * ic/m68k/m68k-execute.c: In the fast executor, assert that the ITLB entry allows fast ! 389: reading for the current PC or that the PC is one greater than ! 390: the last address covered by the entry. Fixed the fast-fetch-failed ! 391: code to more correctly simulate a group 0 exception and associated ! 392: RTE. ! 393: ! 394: * ic/m68k/m68k-insns-auto.sh: Cleaned up and fixed the code generated for cmpm, addx, and subx. ! 395: At least, cmpm wasn't getting its address registers postincremented, ! 396: and addx and subx weren't treating the Z flag properly. ! 397: In the fetch insns, take the address to fetch from as an argument, !

413: tme_sjlj_cond_wait_yield was called; the thread itself ! 414: will relock the mutex when it is restarted. ! 415: ! 416: * machine/sun2/Makefile.am: Now build and link against the Multibus and BSD libraries. ! 417: * machine/sun2/sun2-test.c (tme_memdup): Added. ! 418: (connect_elements): Now start the new convention of initializing ! 419: the new-connections lists to NULL and letting the new-connections !

Added many new instructions, including ! 807: multiply and divide. ! 808: ! 809: Sat Apr 05 18:47:38 2003 Matthew Fredette <[email protected]> ! 810: ! 811: * machine/Makefile.am: Added. ! 812: ! 813: Tue Apr 01 20:13:07 2003 Matthew Fredette <[email protected]> ! 814: ! 815: * ic/m68k/Makefile.am: Build decoders for the 68000, 68010, and 68020. ! 816: * ic/m68k/m68k-iset-expand.pl: Added a very basic preprocessor to support generating ! 817: different instruction sets for different CPUs. ! 818: Now whenever an instruction wants the EA, its operand ! 819: is eax.32 even if the known EA is address register indirect. ! 820: ! 821: * ic/m68k/m68k-iset.txt: This should be the complete integer instruction set for the ! 822: 68000, 68010, 68020, and 68030. ! 823: ! 824: * ic/m68k/m68k-opmap-make.pl: Added comments, and reworked to support compiling instruction ! 825: sets for different CPUs together, reusing submaps and opcode ! 826: maps whenever possible. ! 827: ! 828: * ic/m68k/m68k.h: Before the -impl.h split. ! 829: ! 830: Sun Mar 30 22:04:15 2003 Matthew Fredette <[email protected]> ! 831: ! 832: * ic/m68k/Makefile.am: Added. ! 833: * ic/m68k/m68010.c: Added. ! 834: * ic/m68k/m68k-execute.c: Added. ! 835: * ic/m68k/m68k-insns-auto.sh: Added. ! 836: * ic/m68k/m68k-insns.c: Added. ! 837: * ic/m68k/m68k-iset-expand.pl: Added. ! 838: * ic/m68k/m68k-iset.txt: Added. ! 839: * ic/m68k/m68k-misc-auto.sh: Added. ! 840: * ic/m68k/m68k-misc.c: Added. ! 841: * ic/m68k/m68k-opmap-make.pl: Added. ! 842: * ic/m68k/m68k.h: Added. ! 843: ! 844: Sun Mar 30 22:04:15 2000 Matthew Fredette <[email protected]> ! 845: ! 846: * Dummy entry.
