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 183: address_mask to address_last, as nothing depended on the 184: address_mask being all-bits-one. 185: 186: * ic/z8530.c: Bulk change to no longer require bus connections to have a 187: 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

(main): Fixed a bug where the zs0 ipl arg was getting lost. 273: 274: Mon May 05 23:08:13 2003 Matthew Fredette <[email protected]> 275: 276: * TODO: Updated. 277: * generic/serial.c (tme_serial_buffer_copyout): Fixed a bug where if we were 278: copying to a NULL buffer and the copyout wrapped in the 279: ring buffer, we would do pointer arithmetic on the NULL. 280: 281: * ic/m68k/m68010.c (_tme_m68010_rte): Fixed a bug where we forgot to recover 282: the group 0 function code and address for the cycle restart. 283: Fixed a bug where we wouldn't reset to extract our internal 284: state from the stack buffer. 285: 286: * ic/m68k/m68k-insns-auto.sh: Fixed several instructions that trap or do trap-like things 287: to update PC to be the PC of the following instruction before 288: trapping. 289: (tme_m68k_read_mem): Fixed a memcpy direction bug. 290: 291: * ic/m68k/m68k-insns.c: Fixed several instructions that trap or do trap-like things 292: to update PC to be the PC of the following instruction before 293: trapping. 294: 295: * libtme/threads-sjlj.c (tme_sjlj_cond_notify): Fixed a bug where we would cancel 296: a thread's wait condition instead of notifying the thread. 297: 298: * machine/sun/sun-mmu.c (tme_sun_mmu_tlb_fill): Support the new expansive MMU PTE 299: protections. 300: 301: * machine/sun2/sun2-mainbus.c (_tme_sun2_bus_intack): Now acknowledge soft interrupts. 302: (tme_machine_sun2_clock_new): Fixed a bug where we had the 303: Timer 2 output miswired. 304: 305: * machine/sun2/sun2-mmu.c: Many changes to support the new full

hate doing this, too much work to go into detail. 321: Did more groundwork for eventually generating interrupts. 322: 323: * ic/m68k/m68k-execute.c: Now wrap the execute hook call in _TME_M68K_OPW_OK. 324: * ic/m68k/m68k-misc.c (tme_m68k_exception_process_start): Fixed a bug where the new 325: ipl mask was put into the sr at the wrong position. 326: 327: * machine/sun2/sun2-mainbus.c

(_tme_sun2_obmem_fault_handler): Added. 332: (_tme_sun2_multibus_fault_handler): Now just call 333: _tme_sun2_bus_fault_handler. 334: (_tme_sun2_tlb_fill_mmu): Use the new bus-specific 335: fault handlers. 336: 337: * machine/sun2/sun2-test.c: Now create and connect the TOD chip. 338: * tme/ic/Makefile.am: Updated. 339: * tme/ic/mm58167.h: Added. 340: 341: Sat May 03 19:27:07 2003 Matthew Fredette <[email protected]> 342: 343: * TODO: Updated. 344: * ic/m68k/m68k-execute.c: Fixed multiple bugs in the handling of brief EA extension words. 345: * ic/m68k/m68k-insns-auto.sh: Fixed a bug

(_tme_am9513_counters_load): 376: (_tme_am9513_counters_arm): Added. 377: (_tme_am9513_th_timer): Try to avoid multiplication overflow 378: when calculating the number of basic ticks that have elapsed. 379: Try to handle armed and unarmed counters correctly. 380: (_tme_am9513_bus_cycle): Now load and arm counters correctly. 381: (tme_ic_am9513_new): Calculate the number of basic ticks in 382: a millisecond for the benefit of the timer thread. 383: 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, 398: instead of using the real ic->tme_m68k_ireg_pc with tme_m68k_read 399: (which could actually update it, if recovering from a group 0 400: exception!) 401: 402: * ic/m68k/m68k-misc-auto.sh: The slow-executor fetch macros now call the fetch insns with the 403: PC to fetch from. 404: 405: * ic/m68k/m68k-misc.c (tme_m68k_rte_finish): No longer do anything with the sequence 406: at all, just redispatch it. 407: (tme_m68k_sequence_fill): Now set the sequence next-transfer to 408: one, to force a restart in case later code doesn't. 409: (tme_m68k_insn_buffer_xfer): The insn buffer is kept in host 410: byte order, not big-endian byte order. 411: 412: * libtme/threads-sjlj.c: No longer track and relock a mutex that was held when 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.
