1.1.1.3 ! root 1: Sun May 15 01:24:11 2005 Matthew Fredette <[email protected]> ! 2: ! 3: * Release 0.4 out. ! 4: ! 5: * configure.in: Fixed a bug where StaticGray, StaticColor, and ! 6: PseudoColor visuals would be considered indexed. This would cause the ! 7: translation functions to incorrectly try to map intensities into pixel ! 8: subfields. ! 9: ! 10: Sat May 14 22:28:29 2005 Matthew Fredette <[email protected]> ! 11: ! 12: * TODO: Updated. ! 13: ! 14: * acinclude.m4 (AC_CHECK_FUNC_LONG): Added. ! 15: ! 16: * configure.in: Now check for sys/bswap.h, bswap16(), and bswap32(). ! 17: Now check for isinff(). ! 18: Instead of taking a set of host display formats in the environment ! 19: variable TME_DISPLAYS, now take the configure argument ! 20: --with-tme-host-displays. When debugging is disabled, to get best ! 21: performance now define macros that preprocess out a lot of debugging ! 22: code. Debugging now defaults to disabled. ! 23: ! 24: * generic/float.c [!HAVE_ISINFF] (isinff): Added. ! 25: ! 26: * host/gtk/gtk-screen.c (_tme_gtk_screen_mode_change): Now initially ! 27: try to allocate new colors. For any colors that fail, try to allocate ! 28: best-match colors. Warn if even best-match colors could not be ! 29: allocated. ! 30: ! 31: * ic/ieee754/ieee754-misc.c: Declare more single- and double-precision ! 32: constants. ! 33: ! 34: * tme/common.h: Now include <sys/bswap.h> for the byteswapping ! 35: functions. When the host is big-endian, try to use bswap16() and ! 36: bswap32() for byteswapping functions, otherwise define them. Now ! 37: define little-endian conversion functions on big-endian hosts. ! 38: ! 39: * tme/generic/float.h: Corrected some HAVE_ macros to _TME_HAVE_ ! 40: macros. Now include float.h and limits.h. Added a prototype for ! 41: isinff(). ! 42: ! 43: Sat May 14 19:18:42 2005 Matthew Fredette <[email protected]> ! 44: ! 45: * generic/fb-xlat-auto.sh: Fixed a bug in the initialization of ! 46: dst_masks_default, that was causing incorrect halving translation on ! 47: PseudoColor hosts. ! 48: ! 49: * host/gtk/gtk-keyboard.c (_tme_gtk_keyboard_lookup): Fixed a bug in ! 50: the warning message when a keysym can't be generated by the host ! 51: keyboard. ! 52: ! 53: * ic/ieee754/Makefile.am: Added -lm to libtme_ieee754_la_LDFLAGS. ! 54: ! 55: * ic/m68k/m68k-opmap-dump.c: ! 56: * machine/sun3/sun3-carrera-eeprom.txt: Added. ! 57: ! 58: * ic/m68k/m68k-opmap-make.pl: The previous opcode map functions were ! 59: too big (or complicated?) to be compiled in a reasonable amount of ! 60: time on slower machines. Now compress the functions down by ! 61: initializing similar roots close to each other, and in groups whenever ! 62: possible. This cuts down on the amount of params[] refilling and ! 63: function calls, and decreases the size of m68k-opmap.c by almost half. ! 64: ! 65: * machine/sun3/Makefile.am: Added sun3-carrera-eeprom.txt to ! 66: examples_DATA. ! 67: ! 68: * serial/serial-kb.c (_tme_serial_kb_connection_make): When a keyboard ! 69: macro can't be parsed, instead of aborting, just log a complaint. ! 70: ! 71: Sat May 14 01:43:33 2005 Matthew Fredette <[email protected]> ! 72: ! 73: * acinclude.m4 (AC_CHECK_FLOAT_FORMAT): Fixed a tme_uint16_t, which ! 74: was causing failures on big-endian systems. ! 75: ! 76: * ic/ieee754/softfloat-tme.c: Swapped some declarations that were with ! 77: the wrong comments. ! 78: ! 79: * tme/ic/ieee754.h: Declare more single- and double-precision ! 80: constants. ! 81: ! 82: Wed May 11 00:15:42 2005 Matthew Fredette <[email protected]> ! 83: ! 84: * dist/softfloat/softfloat/bits64/softfloat-macros (add192): ! 85: (sub192): Fixed some gcc3 signed/unsigned comparison warnings. ! 86: ! 87: * dist/softfloat/softfloat/bits64/softfloat.c (roundAndPackFloatx80): ! 88: Fixed a gcc3 signed/unsigned comparison warning. ! 89: ! 90: * ic/i825x6.c (_tme_i825x6_callout_ru): ! 91: (_tme_i825x6_callout): Fixed some gcc3 signed/unsigned comparison ! 92: warnings. ! 93: ! 94: * ic/ieee754/ieee754-misc-auto.sh: Fixed a gcc3 signed/unsigned ! 95: comparison warning. ! 96: ! 97: * machine/sun3/sun3-mainbus.c (_tme_sun3_bus_intack): Make signal ! 98: unsigned, to fix gcc3 signed/unsigned comparison warnings. ! 99: ! 100: * tme/generic/float.h (tme_float_is_negative): Fixed all conditional ! 101: arms to be conditional expressions, to keep the type of the whole ! 102: expression int. ! 103: ! 104: Tue May 10 11:15:26 2005 Matthew Fredette <[email protected]> ! 105: ! 106: * machine/sun3/SUN3-CARRERA: Disable obie0 by default. ! 107: ! 108: Tue May 10 00:38:19 2005 Matthew Fredette <[email protected]> ! 109: ! 110: * host/gtk/gtk-keyboard.c (_tme_gtk_keyboard_attach): Connect the ! 111: key_press and key_release events with gtk_signal_connect_after, so we ! 112: can stop the event from propagating up to parents, where a GtkWindow ! 113: parent will do strange things with arrow key presses. ! 114: ! 115: * ic/isil7170.c (_tme_isil7170_bus_cycle): Fixed an off-by-one bug in ! 116: the month register. ! 117: ! 118: * machine/sun3/SUN3-CARRERA: Disable the serial console by default. ! 119: ! 120: Mon May 09 02:01:02 2005 Matthew Fredette <[email protected]> ! 121: ! 122: * machine/sun/sun-cgtwo.c (_tme_suncg2_bus_cycle_regs): Wrap the ! 123: rasterop register log in #ifndef TME_NO_LOG, since the rasterop ! 124: register names array doesn't exist otherwise. ! 125: ! 126: Mon May 09 01:59:03 2005 Matthew Fredette <[email protected]> ! 127: ! 128: * generic/ethernet.c (tme_ethernet_chunks_copy): Fixed a bug where the ! 129: size of the destination buffer would get loaded with the size of the ! 130: source buffer. ! 131: ! 132: * generic/fb.c (_tme_fb_xlat_colors_get_set): Fixed a bug where the ! 133: number of colors allocated wasn't being saved. ! 134: ! 135: * ic/i825x6.c (_tme_i825x6_fbl_refill): Now tolerate a Receive Buffer ! 136: with zero size. ! 137: (_tme_i825x6_callout_ru): Initialize rbd_size early, since its value ! 138: is decreased early when a fake receive buffer is made from the RFD ! 139: Ethernet header space. ! 140: ! 141: Sat Apr 30 15:22:25 2005 Matthew Fredette <[email protected]> ! 142: ! 143: * configure.in: Now determine the default display depth with xwininfo ! 144: -root, assuming that the root window is at the default depth. If the ! 145: depth is greater than one, also determine the visual class and any ! 146: subfield masks, and include this information in the destination image ! 147: key. Add support for color framebuffer images on the sun3. ! 148: ! 149: * generic/bus.c (_tme_bus_cycle_xfer_resp_least_lane): ! 150: (tme_bus_cycle_xfer_reg): Added. ! 151: ! 152: * generic/fb-xlat-auto.sh: Added support for color source and ! 153: destination images. ! 154: ! 155: * generic/fb.c (tme_fb_xlat_best): ! 156: (tme_fb_xlat_is_optimal): Now consider source image class, mapping ! 157: type, mapping size, and subfield masks, and destination image mapping ! 158: type and subfield masks. ! 159: (_tme_fb_xlat_colors_get_set): ! 160: (tme_fb_xlat_colors_get): ! 161: (tme_fb_xlat_colors_set): Added. ! 162: ! 163: * host/gtk/gtk-display.h: Removed the monochrome invert mask from ! 164: struct tme_gtk_display. Inversion is now specified by the ! 165: framebuffer. ! 166: ! 167: * host/gtk/gtk-screen.c (_tme_gtk_screen_mode_change): Added color ! 168: support. Now we determine the destination image class, mapping, and ! 169: any subfield masks. We choose a translation function based on image ! 170: classes, mappings, and subfield masks, and allocate colors on behalf ! 171: of the translation function. ! 172: ! 173: * ic/m68k/m68020.c (_tme_m68020_exception): Fixed a bug where a 32-bit ! 174: fetch wasn't marking the B stage as faulted. ! 175: ! 176: * ic/m68k/m68k-execute.c (_TME_M68K_EXECUTE_NAME): Fixed a bug with ! 177: the instruction buffer. Before, when the slow executor would take a ! 178: fault in the middle of a 32-bit instruction fetch, the successfully ! 179: fetched first 16 bits wouldn't get put in the instruction buffer by ! 180: the fault processing, because a fetch was only accounted for once it ! 181: fully succeeded. When the fetch was resumed, the first 16 bits was ! 182: lost. Now, a slow executor fetch is accounted for before it begins, ! 183: which guarantees that any partially fetched instruction makes it into ! 184: the instruction buffer. ! 185: ! 186: * ic/m68k/m68k-misc-auto.sh: Now, we update the instruction buffer ! 187: fetch total and sizes values before we do the actual fetch, because we ! 188: may transfer a few bytes and then fault. Without this, those few ! 189: bytes wouldn't get saved in the exception stack frame by ! 190: tme_m68k_insn_buffer_xfer(), because it wouldn't know about the fetch. ! 191: Later, when the instruction would be resumed, tme_m68k_fetch32() won't ! 192: refetch them, because it knows they've already been fetched and thinks ! 193: they're still in the instruction buffer. ! 194: ! 195: * machine/sun/Makefile.am: Now build sun-cgtwo.c for ! 196: libtme_machine_sun.la. ! 197: ! 198: * machine/sun/sun-bwtwo.c (_tme_sunbw2_connections_new): Fill in the ! 199: new parts of the struct tme_fb_connection. ! 200: (tme_sun_bwtwo): Fixed a bug in the argument processing. ! 201: ! 202: * machine/sun/sun-cgtwo.c: Added. ! 203: ! 204: * machine/sun2/SUN2-MULTIBUS: Since the Emulex emulation changed ! 205: slightly, make sure that NetBSD will still probe this as an Emulex. ! 206: ! 207: * machine/sun3/SUN3-CARRERA: Added support for the cgthree board. ! 208: ! 209: * machine/sun3/sun3-mainbus.c (tme_machine_sun3,cgtwo): Added. ! 210: ! 211: * machine/sun3/sun3-mmu.c (_tme_sun3_tlb_fill_mmu): Temporarily work ! 212: around a bug in NetBSD/sun3 where the cgtwo is mapped at the wrong ! 213: physical address. ! 214: ! 215: * tme/generic/bus.h: Added a prototype for tme_bus_cycle_xfer_reg(). ! 216: ! 217: * tme/generic/fb.h: Added macros for the different image classes, ! 218: mapping types, and default subfield masks. Also added macros for the ! 219: "any" subfield mask, and for the mask of the maximum index value. ! 220: Expanded struct tme_fb_connection and struct tme_fb_xlat to include ! 221: image class, subfield masks, and mapping information. Added ! 222: prototypes for tme_fb_xlat_colors_get() and tme_fb_xlat_colors_set(). ! 223: ! 224: * tme/machine/sun.h: Added a prototype for tme_sun_cgtwo(). ! 225: ! 226: Wed Mar 23 12:42:56 2005 Matthew Fredette <[email protected]> ! 227: ! 228: * ic/ieee754/ieee754-ops-auto.sh: Now emit ops for log, log10, and ! 229: exp. ! 230: ! 231: * ic/m68k/m68010.c: TME_ELEMENT_X_NEW_DECL(tme_ic_,m68k,m68010): Now ! 232: call tme_m68k_opcodes_init_m68010() to initialize the opcode table. ! 233: ! 234: * ic/m68k/m68020.c: TME_ELEMENT_X_NEW_DECL(tme_ic_,m68k,m68020): Now ! 235: call tme_m68k_opcodes_init_m68020() to initialize the opcode table. ! 236: ! 237: * ic/m68k/m6888x.c (tme_m68k_fbcc): Fixed a bug in calculating the ! 238: target PC; the displacement is always added to the original PC plus ! 239: two. Now always take a 32-bit displacement as a proper operand. ! 240: ! 241: * ic/m68k/m68k-execute.c: Simplified how instructions are decoded and ! 242: executed. Now, the first 16-bit instruction word is used to directly ! 243: index an array of 32-bit integers, each of which gives the ! 244: instruction's function number, the function's arguments, immediate ! 245: fetching and EA calculation information, and a single ! 246: special-operation escape bit. Only two types of immediate fetches are ! 247: supported: a 16-bit fetch, sign-extended to 32 bits, and a 32-bit ! 248: fetch. All of this speeds things up dramatically. ! 249: [_TME_M68K_STATS]: Keep statistics on executed instructions. ! 250: ! 251: * ic/m68k/m68k-impl.h: Removed TME_M68K_SIZE_SUBMAP_X, ! 252: TME_M68K_SIZE_16U8, TME_M68K_SIZE_16S32, TME_M68K_OPNUM_SUBMAP_X, ! 253: TME_M68K_OPNUM_UNDEF, and the list of special opcodes, all of which ! 254: were used only in the old opcode maps. ! 255: Added macros for the decoded instruction parameters in the new opcode ! 256: maps. ! 257: Removed the data structures used by the old opcode maps. The EA ! 258: register is now a proper IC register. Added statistics to struct ! 259: tme_m68k. Removed the declarations of the small immediate arrays. ! 260: The small immediates are now proper IC registers. Added declarations ! 261: of the different CPUs' opcode maps and their initialization functions, ! 262: and the instruction function array. Added declarations for ! 263: tme_m68k_bccl(), tme_m68k_bsrl(), tme_m68k_divl() and tme_m68k_mull(). ! 264: ! 265: * ic/m68k/m68k-insns.c (tme_m68k_bccl): ! 266: (tme_m68k_bsrl): ! 267: (tme_m68k_link): ! 268: (tme_m68k_rtd): Now that the opcode map supports 16-bit immediates ! 269: sign-extended to 32 bits, always take a proper 32-bit operand. ! 270: ! 271: * ic/m68k/m68k-iset.txt: Now that the opcode map supports 16-bit ! 272: immediates sign-extended to 32 bits again, make rtd and the 16-bit ! 273: versions of link, bsr, bcc, and fbcc take this kind of immediate. ! 274: ! 275: * ic/m68k/m68k-misc.c (tme_m68k_exception): Now log a message when a ! 276: double fault causes a processor halt. ! 277: ! 278: * ic/m68k/m68k-opmap-make.pl: The initial rewrite of the opcode map ! 279: generation resulted in an enormous opcode map source file, and, ! 280: because the instruction function pointers were in the map entries ! 281: directly, an opcode map array that wasn't 64-bit friendly. ! 282: Now, the instruction function pointers are in a small separate array ! 283: which is indexed by eight bits in the 32-bit opcode parameter ! 284: information, which is all that remains in the opcode map. To make ! 285: room for these eight bits, the first EA mode and reg fields are not ! 286: stored (and are instead are swapped in by the instruction executer ! 287: after the instruction function has been fetched), and the special ! 288: operation field has been reduced to a single bit. To shrink the ! 289: opcode map sources, we take advantage of the fact that each of the ! 290: 1024 aligned sets of 64 opcodes (a "root") uses one of a small number ! 291: of patterns to initialize itself (for m68000 through m68020, there are ! 292: only 37 such patterns), and we generate a function to initialize the ! 293: parameters in that pattern. Also, each CPU uses the previous CPU's ! 294: opcode initialization function to initialize the bulk of its opcode ! 295: map, making changes only as needed. ! 296: All of this has reduced the size of the opcode map source file ! 297: dramatically. ! 298: Also, support for 16-bit immediates, sign-extended to 32 bits, has ! 299: been added again. ! 300: ! 301: Tue Mar 15 02:56:58 2005 Matthew Fredette <[email protected]> ! 302: ! 303: * ic/m68k/m6888x.c (tme_m68k_fbcc): All 16-bit immediates are now ! 304: sign-extended to 32-bits in a fixed immediate register. ! 305: ! 306: * ic/m68k/m68k-insns.c (_tme_m68k_bcc): ! 307: (tme_m68k_bccl): ! 308: (_tme_m68k_bsr): ! 309: (tme_m68k_bsrl): Added. ! 310: (tme_m68k_bcc): Now just use _tme_m68k_bcc. ! 311: (tme_m68k_bsr): Now just use _tme_m68k_bsr. ! 312: (tme_m68k_link): Now handle the 16-bit variant explicitly. ! 313: (tme_m68k_rtd): Now handle our 16-bit argument correctly. ! 314: (tme_m68k_mull): ! 315: (tme_m68k_divl): Added. ! 316: ! 317: Thu Mar 10 13:29:42 2005 Matthew Fredette <[email protected]> ! 318: ! 319: * ic/m68k/m68010.c: Now define _TME_M68K_EXECUTE_OPMAP to ! 320: tme_m68k_opcodes_m68010 when compiling the executors. ! 321: TME_ELEMENT_X_NEW_DECL(tme_ic_,m68k,m68010): No longer call ! 322: _tme_m68010_decoder_map_init(). ! 323: ! 324: * ic/m68k/m68020.c: Now define _TME_M68K_EXECUTE_OPMAP to ! 325: tme_m68k_opcodes_m68020 when compiling the executors. ! 326: TME_ELEMENT_X_NEW_DECL(tme_ic_,m68k,m68020): No longer call ! 327: _tme_m68020_decoder_map_init(). ! 328: ! 329: * ic/m68k/m68k-insns-auto.sh: cas2 now gets its specop2 as a 16-bit ! 330: operand. moves now must do its own memory cycles, and EA ! 331: postincrement and predecrement. ! 332: Now track memory statistics in the memory functions. ! 333: ! 334: * ic/m68k/m68k-iset.txt: Many simplifications, and some expansions, to ! 335: enable faster instruction dispatching. Eliminated all specops except ! 336: for specop16 and fpgen, eliminated the #16S32 immediate type (all ! 337: 16-bit immediates are now sign-expanded to 32 bits), and bcc and bsr ! 338: are now expanded (multiple iset lines may expand to the same pattern, ! 339: with the first one winning, but also with a system of * understood by ! 340: m68k-opmap-make.pl to count the correct number of duplicates). ! 341: ! 342: * ic/m68k/m68k-misc-auto.sh: Now define a 96-bit register for ! 343: immediates. Now define registers for the constants zero through ! 344: eight. ! 345: ! 346: * ic/m68k/m68k-misc.c: Removed the small immediates arrays. ! 347: (_tme_m68k_connection_break): Now return zero, to silence a warning ! 348: (?). ! 349: (tme_m68k_new): Increased the instruction burst size to 200. This ! 350: dramatically improves performance. Now initialize the small ! 351: immediates. ! 352: (tme_m68k_redispatch): Count redispatch statistics. ! 353: (tme_m68k_tlb_fill): Count TLB fill statistics. ! 354: (tme_m68k_dump): No longer display the specop2 value. ! 355: ! 356: * ic/m68k/m68k-opmap-make.pl (operand_final): Removed. ! 357: ! 358: * ic/m68k/m68k-opmap-make.pl: Rewritten to support much faster ! 359: dispatching of instructions. Now each CPU gets an independent ! 360: 64K-entry array, indexed by first instruction word, that yields a ! 361: function pointer and 32 bits of parameter information.

This works around a sleep/wakeup race condition in ! 418: the NetBSD kernel RARP code. ! 419: Changed the type of the bwtwo from obmem to multibus, since the bwtwo ! 420: implementation is now common to all sun machines. ! 421: ! 422: * machine/sun3/SUN3-CARRERA: Now define an unknown-compliance m68881. ! 423: Now use the revision 3.0 ROM. ! 424: Increased the size of the VME bus to the full 4GB. Commented out the ! 425: sc0 attachment, in favor of the new si0 attachment. ! 426: To support stock NetBSD 1.6*, make the Emulex tape respond to INQUIRY ! 427: commands in a normal way. ! 428: ! 429: * machine/sun3/sun3-control.c (_tme_sun3_control_cycle_handler): Call ! 430: out changes to the FPU and DVMA enable bits. Silently ignore an ! 431: attempt to enable the Sun FPA. ! 432: ! 433: * machine/sun3/sun3-impl.h: Now track the active DVMA TLBs, so that ! 434: they can be invalidated when DVMA is enabled or disabled. Atomic ! 435: variable fixes, and a prototype for _tme_sun3_mmu_sdvma_change(). ! 436: ! 437: * machine/sun3/sun3-mmu.c (_tme_sun3_cycle_dummy): ! 438: (_tme_sun3_sdvma_disabled): ! 439: (_tme_sun3_mmu_sdvma_change): Added. ! 440: (_tme_sun3_bus_tlb_fill): Now track TLB entries filled for DVMA space. ! 441: Entries that are filled while DVMA is disabled generate a VME bus ! 442: fault. For now, bus cycles to unmapped DVMA addresses are ignored. ! 443: (_tme_sun3_tlb_fill_mmu): Apparently the magic obio mapping of the ! 444: PROM works over a PROM-sized region starting at 0x100000. Made some ! 445: changes to silence -Wuninitialized. ! 446: (_tme_sun3_mmu_tlb_set_allocate): Atomic variable changes. ! 447: ! 448: * scsi/scsi-bus.c: Replaced the idea of a SCSI sequence with the much ! 449: simpler idea of a bus agent waiting for one or more SCSI events to ! 450: happen, then taking one or more SCSI actions. ! 451: (_tme_scsi_bus_callout): Now call out the events triggered and actions ! 452: taken to the connection. ! 453: (_tme_scsi_bus_cycle): Now take the events to wait on and the actions ! 454: to take from the connection. A connection waits until one of its ! 455: events triggers, then some part of its actions are taken. There is ! 456: now support for half and full SCSI bus arbitration, and reselection. ! 457: (_tme_scsi_bus_sequence_get): Removed. ! 458: (_tme_scsi_bus_connection_score): ! 459: (_tme_scsi_bus_connections_new): We can't provide a predefined ! 460: sequence function any more, or score a connection based on one. ! 461: ! 462: * scsi/scsi-device.c (_tme_scsi_device_callout): ! 463: (_tme_scsi_device_cycle): More or less mechanical changes to support ! 464: the new events/actions SCSI bus interface. Fixed a bug where we would ! 465: go past the end of the message dispatch array for IDENTIFY messages. ! 466: (tme_scsi_device_connections_new): Removed the predefined SCSI ! 467: sequence member assignment. ! 468: ! 469: * scsi/scsi-tape.c (tme_scsi_tape_cdb_inquiry): It looks like ! 470: nonexistent LUNs are reported as "unsupported", and not "not present". ! 471: Now identify as a SCSI-1 device, and be sure not to return more data ! 472: than the initiator requested. ! 473: ! 474: * tme/common.h: Now declare _tme_volatile. ! 475: Added some missing parentheses to _TME_FIELD_DEPOSIT(). Fixed a bug ! 476: in the definition of the tme_value64_uint32s[] member of union ! 477: tme_value64. ! 478: Added definitions for tme_value64_imul() and tme_value64_idiv(). ! 479: ! 480: * tme/generic/Makefile.am: Now install float.h. ! 481: ! 482: * tme/generic/bus.h: Now define TME_BUS_SIGNAL_DRQ and ! 483: TME_BUS_SIGNAL_DACK. ! 484: ! 485: * tme/generic/scsi.h: Now define TME_SCSI_ID_SELECTED() and ! 486: TME_SCSI_ID_RESELECTED(), to determine if an ID is being selected or ! 487: reselected. Replaced the idea of a SCSI sequence with the much ! 488: simpler idea of a bus agent waiting for one or more SCSI events to ! 489: happen, then taking one or more SCSI actions. ! 490: ! 491: * tme/ic/Makefile.am: Now install i825x6.h and ieee754.h. ! 492: ! 493: * tme/machine/sun.h: Added a prototype for tme_sun_si(). ! 494: ! 495: * tme/scsi/scsi-device.h: Removed the old predefined SCSI sequences ! 496: from struct scsi_device. ! 497: ! 498: * tme/scsi/scsi-msg.h: Now define TME_SCSI_MSG_IDENTIFY_LUN_MASK, for ! 499: getting the LUN out of an IDENTIFY message. ! 500: ! 501: * tmesh/tmesh-input.y: Now define YYMAXDEPTH, to silence -Wundef. ! 502: ! 503: Thu Feb 17 13:42:44 2005 Matthew Fredette <[email protected]> ! 504: ! 505: * Makefile.am: Added tools/ to SUBDIRS, and dist/ to EXTRA_DIST. ! 506: Added a dist-hook target to clean the CVS directories out of dist/. ! 507: ! 508: * acinclude.m4 (AC_CHECK_FLOAT_FORMAT): ! 509: (AC_CHECK_FLOAT_LIMITS): Added. ! 510: ! 511: * configure.in: Bumped version to 0.4. ! 512: Now check for limits.h and float.h. Check for volatile, float, ! 513: double, and long double, and the signal handler type. ! 514: Added ieee754 and ncr5380 to the list of sun3 ICs. When using gcc, ! 515: now use -Wundef when compiling with warnings, and set the no strict ! 516: aliasing flag. Add the floating point format configuration to ! 517: tmeconfig.h. ! 518: ! 519: * generic/Makefile.am: Now build float.c and float-auto.c, and include ! 520: float-auto.sh and float-auto.c in the distribution. ! 521: ! 522: * generic/bus-el.c generic/bus.c machine/sun/sun-mmu.c ! 523: machine/sun/sun-obie.c machine/sun2/sun2-impl.h ! 524: machine/sun2/sun2-mmu.c tme/atomics.h tme/generic/bus.h ! 525: tme/machine/sun.h: ! 526: ! 527: Cleaned up atomic variables. Now atomic variables declared with ! 528: TME_ATOMIC and TME_ATOMIC_POINTER_TYPE are volatile. To do this ! 529: right, TME_ATOMIC_POINTER_TYPE changed to take just the base type ! 530: pointed to, so there has been some fallout. ! 531: ! 532: * generic/float-auto.sh generic/float.c ic/ncr5380.c ! 533: ic/ieee754/Makefile.am ic/ieee754/ieee754-misc-auto.sh ! 534: ic/ieee754/ieee754-misc.c ic/ieee754/ieee754-ops-auto.sh ! 535: ic/ieee754/ieee754-precision.sh ic/ieee754/softfloat-tme.c ! 536: ic/ieee754/softfloat-tme.h ic/m68k/m6888x-auto.sh ic/m68k/m6888x.c ! 537: machine/sun/sun-si.c tme/generic/float.h tme/ic/ieee754.h ! 538: tools/Makefile.am: ! 539: ! 540: Added. ! 541: ! 542: * host/posix/posix-disk.c (tme_host_posix,disk): Only probe for the ! 543: block size if the device is a character device. If we have mmap ! 544: support, the block size for all devices must be some multiple of the ! 545: page size - this fixes a bug where we would try to mmap() ! 546: non-page-sized regions at non-page boundaries. ! 547: ! 548: * ic/Makefile.am: Added ieee754 to the list of distribution ! 549: subdirectories. Now build ncr5380.c. ! 550: Added i825x6reg.h to the list of i825x6 sources. ! 551: ! 552: * ic/m68k/m68020.c (_tme_m68020_exception): ! 553: (_tme_m68020_rte): Fixed bugs in the handling of bus fault frames for ! 554: instruction fetches. Previously, we would always fault on stage B, ! 555: and only on stage C for a 32-bit fetch. This was supposed to be the ! 556: other way around. Also, an address error doesn't set a fault bit, ! 557: only a rerun bit. ! 558: ! 559: * ic/m68k/m68k-execute.c (_TME_M68K_EXECUTE_NAME): Fixed some bugs ! 560: caught by gcc -Wuninitialized. ! 561: ! 562: * ic/m68k/m68k-opmap-make.pl: Fixed a bug where the illegal opcode ! 563: wouldn't get the 'illegal' specop. ! 564: ! 565: * libtme/threads-sjlj.c [HAVE_GTK]: Define G_ENABLE_DEBUG if it isn't ! 566: defined, to silence -Wundef. ! 567: ! 568: * machine/sun/sun-mmu.c (tme_sun_mmu_tlb_fill): Fixed a serious bug ! 569: where any page marked as modified was given out as writable, even if ! 570: it wasn't marked as writable. SunOS likes to set page table entries ! 571: that are modified, but not writable, and this bug was preventing ! 572: proper copy-on-write behavior. ! 573: ! 574: * machine/sun2/Makefile.am: No longer build sun2-bwtwo.c. ! 575: ! 576: * machine/sun2/sun2-bwtwo.c: Removed. ! 577: ! 578: * machine/sun2/sun2-mainbus.c (_tme_sun2_connections_new): Fixed bugs ! 579: in forming the list of free buses. ! 580: (tme_machine_sun2,zs): Now use the standard Sun z8530 socket ! 581: definition. ! 582: (tme_machine_sun2,bwtwo): Added. ! 583: ! 584: * machine/sun3/sun3-mainbus.c (_tme_sun3_bus_signal): Apparently, ! 585: SunOS likes to set both the level 5 and level 7 clock interrupt enable ! 586: bits. The level 5 bit seems to take precedence. ! 587: (_tme_sun3_connection_score): Insist on a m68020 or better. ! 588: (tme_machine_sun3,si): Added. ! 589: ! 590: * scsi/emulexmt02.c (_tme_emulexmt02_cdb_request_sense): Fixed a bug ! 591: where we weren't putting the Emulex error code in the sense. ! 592: (_tme_emulexmt02_cdb_inquiry): Added a hack to make this tape usable ! 593: to install SunOS 4.1.1. ! 594: (tme_scsi_tape_emulexmt02_init): If the user specified a vendor of ! 595: EMULEX, use the normal INQUIRY CDB handling, instead of returning the ! 596: useless Emulex INQUIRY data. Now return an illegal command for a ! 597: RESERVE CDB. ! 598: ! 599: Thu Feb 17 02:14:57 2005 Matthew Fredette <[email protected]> ! 600: ! 601: * ic/m68k/m68k-insns.c (tme_m68k_bfffo): Fixed a bug where we were ! 602: using ffs(), which finds the least significant bit set, and not the ! 603: most significant bit set. Now find the most significant bit set. ! 604: ! 605: * ic/m68k/m68k-verify.c (_tme_m68k_verify_end): Added better support ! 606: for verifying bitfield instructions. Don't try to verify ! 607: floating-point instructions. ! 608: (tme_m68k_verify_end_branch): Now leave the m68k structure unchanged. ! 609: ! 610: * machine/sun/Makefile.am: Added sun-fb.h and sun-si.c to the sources ! 611: list. Added tme-sun-eeprom.pl to the distribution. ! 612: ! 613: Wed Jan 26 13:13:29 2005 Matthew Fredette <[email protected]> ! 614: ! 615: * host/gtk/gtk-display.h: If G_ENABLE_DEBUG isn't defined, define it ! 616: to zero. Some GTK installations apparently require this. ! 617: ! 618: * host/gtk/gtk-screen.c (_tme_gtk_screen_mode_change): Allocate a ! 619: GdkImage with the extra scanlines needed to hold the overtranslation ! 620: that the automatically generated functions do. ! 621: ! 622: * ic/isil7170.c: Include <time.h> and not <sys/types.h> to get struct ! 623: tm. ! 624: ! 625: * ic/m68k/m68020.c (_tme_m68020_exception): Store the memory Z buffer. ! 626: (_tme_m68020_rte): Restore the memory Z buffer. ! 627: ! 628: * libtme/module.c (tme_module_open): Fixed a bug where were freeing ! 629: the tokens array twice. ! 630: ! 631: * scsi/scsi-msg.c (tme_scsi_device_msg_identify): Now set the !

Fixed a bug in the code ! 773: that detects a 32-bit branch. Fixed a bug in decoding the divul and ! 774: mulul extension words. Added missing declarations for some variables ! 775: used in 68020 effective address calculation. ! 776: ! 777: * ic/m68k/m68k-impl.h: Replaced TME_M68K_FLAG_T with TME_M68K_FLAG_T0 ! 778: and TME_M68K_FLAG_T1, and use them wherever possible. Removed the ! 779: GROUPn_ from the TME_M68K_EXCEPTION_ macros, since the original group ! 780: numbers were specific to the 68000 and 68010. Added more exception ! 781: frame format identifier macros. Added new macros for the exception ! 782: vectors. ! 783: (TME_M68K_INSN_BRANCH): ! 784: (TME_M68K_INSN_CHANGE_SR): Improved tracing support. ! 785: ! 786: * ic/m68k/m68k-insns-auto.sh: The old asr expansion (which was the ! 787: same as the lsr expansion, but with a signed operand and result) had ! 788: bugs and also required that right shifts of a signed operand be ! 789: arithmetic. Added a new expansion that fixes these problems. ! 790: Removed the _GROUPn from the TME_M68K_EXCEPTION_ macro names, since ! 791: the group numbers were specific to the 68000 and 68010. Also added ! 792: the new TME_M68K_VECTOR_ macros. ! 793: In the bus-cycle functions, recognize the ! 794: TME_BUS_CYCLE_SYNCHRONOUS_EVENT pseudo-error, and make it force the ! 795: executer to check external events before executing the next ! 796: instruction. ! 797: ! 798: * ic/m68k/m68k-insns.c: Removed the _GROUPn from the ! 799: TME_M68K_EXCEPTION_ macro names, since the group numbers were specific ! 800: to the 68000 and 68010. Also added the new TME_M68K_VECTOR_ macros. ! 801: Where applicable, store the current PC as the last PC before setting ! 802: the next PC as the current PC. This supports format 2 exception ! 803: frames, which stack the address of the instruction that caused the ! 804: exception. ! 805: (tme_m68k_movec): Added support for the 68020 control registers. ! 806: ! 807: * ic/m68k/m68k-misc-auto.sh: Create registers for the next program ! 808: counter, the 68020 cacr and caar, and the always-zero register. ! 809: ! 810: * ic/m68k/m68k-misc.c: Removed the _GROUPn from the ! 811: TME_M68K_EXCEPTION_ macro names, since the group numbers were specific ! 812: to the 68000 and 68010. Also added the new TME_M68K_VECTOR_ macros. ! 813: (_tme_m68k_bus_interrupt): ! 814: (tme_m68k_external_check): Implement a system that prevents NMI from ! 815: being repeatedly accepted. If the interrupt priority mask is already ! 816: seven, only accept an NMI on a transition from deasserted to asserted. ! 817: (tme_m68k_new): Now set the mask of T bits used by the processor. ! 818: (tme_m68k_do_reset): Now clear the E and F bits in the 68020 cacr. ! 819: Fixed a bug where we loaded the initial SSP and PC from supervisor ! 820: data space instead of the correct supervisor program space. ! 821: (tme_m68k_change_sr): Only recognize the M bit on a 68020 or greater, ! 822: and fixed bugs in the selection of the correct stack pointer control ! 823: register. ! 824: (tme_m68k_exception_process): Renamed to tme_m68000_exception_process, ! 825: since the grouping and priority it implements are specific to the ! 826: 68000 and 68010. ! 827: (tme_m68020_exception_process): Added. ! 828: (tme_m68k_bitfield_offset): Simplified the bitfield byte offset ! 829: calculation for negative bit offsets. ! 830: (tme_m68k_bitfield_width): Don't bother masking a bitfield width that ! 831: was encoded in the instruction; it can't be greater than 31. ! 832: (_tme_m68k_bitfield_read): If the bitfield is in memory, note that the ! 833: current instruction can fault. Fixed bugs where we assumed that ! 834: TME_BIT(32) is zero mod 2^32, when it may be 1 because of shift ! 835: limiting, which would cause us to fail to mask and/or sign-extend a ! 836: 32-bit bitfield value correctly. ! 837: (tme_m68k_bitfield_write_unsigned): Fixed a bug where we wouldn't mask ! 838: the value we were given before setting the flags. Fixed bugs where we ! 839: assumed that TME_BIT(32) is zero mod 2^32, when it may be 1 because of ! 840: shift limiting. If the bitfield is in memory, note that the current ! 841: instruction can fault. ! 842: ! 843: * ic/m68k/m68k-verify.c (tme_m68k_verify_mem_any): Fixed a bug where ! 844: we wouldn't properly verify transfers of endianless data. ! 845: (tme_m68k_verify_init): Now set up a full 32-bit address space. ! 846: (_tme_m68k_verify_end): Store %a7 back in its proper stack pointer ! 847: control register, so we can verify changes to the control registers. ! 848: Ignore extra verifier memory reads on bitfield instructions; the ! 849: verifier bitfield implementation often reads addresses not covered by ! 850: the bitfield. ! 851: ! 852: Mon May 17 11:57:01 2004 Matthew Fredette <[email protected]> ! 853: ! 854: * host/bsd/bsd-bpf.c: Added support for the "delay" option, which ! 855: delays all incoming packets for a user-specified number of ! 856: microseconds. ! 857: (_tme_bsd_bpf_read): Fixed a bug where a TME_ETHERNET_READ_PEEK read ! 858: would discard the read packet. ! 859: ! 860: Fri May 14 00:56:19 2004 Matthew Fredette <[email protected]> ! 861: ! 862: * host/bsd/bsd-bpf.c: Removed the unused tme_bsd_bpf_cond_writer ! 863: structure member. ! 864: (tme_host_bsd,bpf): Fixed a bug where we weren't initializing the ! 865: tme_bsd_bpf_conf_reader condition. ! 866: ! 867: Tue May 11 12:03:36 2004 Matthew Fredette <[email protected]> ! 868: ! 869: * ic/i825x6.c: Added some logging. ! 870: (_tme_i825x6_callout_ru): Don't set the B bit in RFD status fields. ! 871: ! 872: * libtme/misc.c (_tme_misc_number_parse): Some changes to silence gcc ! 873: -Wuninitialized. ! 874: ! 875: Tue May 04 01:17:27 2004 Matthew Fredette <[email protected]> ! 876: ! 877: * bus/multibus/sun-mie.c: ! 878: * ic/i825x6.c: ! 879: * ic/i825x6reg.h: ! 880: * tme/ic/i825x6.h: Added. ! 881: ! 882: * machine/sun2/SUN2-MULTIBUS: Added commands to create ie0. ! 883: ! 884: Fri Apr 30 12:11:36 2004 Matthew Fredette <[email protected]> ! 885: ! 886: * bus/multibus/3c400.c bus/multibus/sun-sc.c generic/bus-el.c ! 887: ic/am9513.c ic/z8530.c ic/m68k/m68k-insns.c ic/m68k/m68k-misc.c ! 888: machine/sun2/sun2-mainbus.c tme/generic/bus.h: ! 889: ! 890: Reworked bus signals in several ways: Added the notion of the bus ! 891: signals set. Every bus should support multiple device-specific bus ! 892: signals sets, added by elements connecting to the bus. This enables ! 893: elements to pass these device-specific bus signals to each other. ! 894: Now bus signals are only specified as either asserted or negated, ! 895: and devices almost never signal edges. For devices that only drive ! 896: signals either high or low, you can exclusive-or ! 897: TME_BUS_SIGNAL_LEVEL_ASSERTED with either TME_BUS_SIGNAL_LEVEL_HIGH ! 898: or TME_BUS_SIGNAL_LEVEL_LOW as appropriate, and provide that to the ! 899: device such that the device only needs to exclusive-or that with the ! 900: signal level to get the right asserted or negated level. Also ! 901: expanded the number of generic bits in a signal value, and improved ! 902: the set of macros used to compose and decompose signal values. ! 903: ! 904: * bus/multibus/sun-sc.c generic/bus.c ic/m68k/m68k-misc.c ! 905: machine/sun/sun-mmu.c tme/generic/bus.h: ! 906: ! 907: Made changes to the TLB protocol, to better support reentrant ! 908: devices. Now, a TLB entry passed to a fill function is expected to ! 909: be local on the stack, and it "reserves" the real, backing TLB entry ! 910: in the device's state. This prevents the case where a device tries ! 911: to fill the same backing TLB entry at the same time in two or more ! 912: threads. TLB fill functions for devices that need to invalidate ! 913: outstanding TLBs always invalidate the backing TLB entry. After a ! 914: TLB fill has finished, the caller checks its reservation on the ! 915: real, backing TLB, and copies the local TLB back if the reservation ! 916: has not been broken. Devices that want to use a TLB entry ! 917: immediately after the fill function returns must use the local TLB, ! 918: since it cannot have been invalidated yet. Also made fixes to TLB ! 919: entry users that avoid rereading fields that are destroyed by ! 920: invalidation, after the device has committed to using the TLB entry, ! 921: since invalidation can happen at any time. Also made the TLB ! 922: tme_bus_tlb_emulator_off_read member const. ! 923: ! 924: * generic/Makefile.am: ! 925: * generic/bus-device.c: ! 926: * tme/generic/bus-device.h: Added generic bus-device support for real ! 927: bus interfaces and bus-mastering. ! 928: ! 929: Fri Apr 30 01:46:01 2004 Matthew Fredette <[email protected]> ! 930: ! 931: * TODO: Updated. ! 932: ! 933: * configure.in: Added the i825x6 to the list of ICs for the sun2. ! 934: ! 935: * bus/multibus/Makefile.am: Now compile sun-mie.c. ! 936: ! 937: * ic/Makefile.am: Now build tme_ic_i825x6.la. ! 938: ! 939: * tme/common.h: Added the TME_X_VERSION versioning macros.

We now report with microsecond resolution, since SunOS's probe 1373: routine requires this. 1374: 1375: * ic/z8530.c (_tme_z8530_intack): Simplified and fixed bugs in how 1376: variable interrupt vectors are computed. For now, since there's no 1377: emulation of the IEI pin, we just behave as if it's always tied low, 1378: so we never put any vector on the bus during a hard interrupt 1379: acknowledge. 1380: (_tme_z8530_bus_cycle): Now ignore all WR0 CRC reset commands.
