229
230 01-Nov-2005
231 -----------
232 - Beginning of a NETIO module to handle network I/O with external world.

249 - mtve (aka "Mtv Europe") sent a patch for much better console handling,
250 merge is planned on 03-Nov.
251 - Added a "PA driver" framework.
252
253 03-Nov-2005
254 -----------
255 - The console is better handled: special keys are working, and there

257 - Merging with Mtve patch, that cleans NETIO module and adds features
258 to the console.
259 - Added a clock divisor hack, but it is not completely working.
260 todo: implement a command line option for this.
261
262 08-Nov-2005

272 - Modified the infrastructure to allow the use of CPU groups
273 that share a certain number of devices (per-CPU device array).
274 All device drivers have been modified to handle this.
275 - Took a look at LSI ATMizer II+, which is the circuit used on
276 PA-A3-OC3 boards. The ATMizer is based on a MIPS CPU, so it should
277 be possible to emulate it.
278 - Added a per-CPU dedicated thread.
279

304 scanning of network devices.
305
306 01-Dec-2005
307 -----------
308 - Added a memory logger (FIFO of 10 accesses), this was useful to debug the
309 PA-A1 RX problem.
310 - Fixed a RX buffer chaining problem in PA-A1.
311
312 02-Dec-2005
313 -----------

317
318 05-Dec-2005
319 -----------
320 - Optimized the cp0 count/compare process for the x86_64 platform

379
380 04-Jan-2006
381 -----------
382 - Better understanding of Flash SIMM register with bank number and bank
383 size: modified the Flash SIMM code to handle a 8 Mb flash in 1 bank
384 (emulation of Intel 28F016SA chip) which should be sufficient to store
385 crashinfo files or misc files like configs,...
386 - Added ROM remote logging capabilities (with remote emulator control).
387
388 05-Jan-2006
389 -----------

408 of NPE-175/NPE-225.
409
410 09-Jan-2006
411 -----------
412 - Added support for NPE-175/NPE-225 and added NPEB-IO-FE.

467 on MacOS X (PowerPC).
468
469 24-Jan-2006
470 -----------
471 - Added support for DMA channels on Galileo GT64k controllers since it seems
472 that they may be used by IOS (NPE-400 for sure, other NPE?).
473
474 25-Jan-2006
475 -----------
476 - Added Linux Raw Ethernet driver to the NetIO infrastructure.
477 - Hmm, I'm probably missing something in the DMA/SRAM interaction and
478 endianness...
479
480 26-Jan-2006
481 -----------
482 - The DMA problem is finally fixed, in fact the SRAM can be accessed with
483 byte-swapping.
484 - Added an unicast limiter to the DEC21140, to receive only trafic directed
485 to the virtual machine (+ multicast/broadcast). This is done by analyzing
486 the setup frames (MAC address filter).
487
488 27-Jan-2006
489 -----------
490 - The Linux Raw Ethernet driver needs promiscuous mode to be enabled to
491 receive appropriate packets, added the required code.

493 definitions (for exchanges between VM and host).
494
495 28-Jan-2006
496 -----------
497 - Added parser infrastructure.
498
499 29-Jan-2006
500 -----------
501 - Added a virtual bridge system.
502 - Release 0.2.3b
503
504 31-Jan-2006
505 -----------
506 - Fixed a stupid bug in DMA handling, which in certain conditions can
507 cause an infinite loop.
508
509 01-Feb-2006
510 -----------
511 - Added an "instruction block hash" which avoids lookups in the instruction
512 red-black tree. The IBH table takes only 16 Kb of memory.
513 - Added CRC-12 and CRC-16 functions for future use.
514 - Added a "gen_eth" NetIO driver, which allow to access ethernet interfaces
515 in a portable way (tested on Linux and Cygwin).
516 - Fixes to the PowerPC build on Darwin thanks to Olivier Cahagne.
517 - Minor cosmetic changes to display supported/unsupported PA and NPE.
518 - Release 0.2.3c
519
520 06-Feb-2006
521 -----------
522 - Added working Serial interfaces (PA-4T+) !
523 - Bug: CDP not working with serial interfaces ("debug cdp events" reports
524 a checksum problem).
525
526 07-Feb-2006
527 -----------
528 - Started the 0.2.4 release.
529 - Modified the command line parser to allow many NIO per PA (for example
530 for serials).
531 - A lot of code cleanups in the C7200 initialization.
532 - Added PA-8T support.
533 - To fix: CDP with Serial interfaces: using cp_len (instead of cp_len+4)
534 in packet rx fixes the problem but breaks IP. Probably something related
535 to padding, see how a CDP packet is sent (special flag in tx ring ?)
536 - Added virtual "beqz" instruction.
537 - Added the "-X" option, allowing to use host memory directly instead of
538 mapping a file to simulate RAM (faster).
539 - Beginning of code reorganization to allow multiple instance contexts.
540
541 08-Feb-2006
542 -----------
543 - Added a basic virtual Frame-Relay switch. Unfortunately, LMI must be
544 implemented to maintain links up.
545 - Finally found the problem related to CDP! It was simply a padding problem.
546
547 09-Feb-2006
548 -----------
549 - Add support of promiscuous mode for the DEC21140 "unicast limiter":
550 promiscuous mode is used in bridging configurations.
551 - Fixed another bug with the serial interfaces: it seems that there is
552 a "length substractor" for the txring.
553

1110 this is basic, we count the number of translated pages and we flush when
1111 this number reaches a threshold (512 pages seems to be a good value).
1112 - Integrated a patch from Philipp Brenner (BTS entry #21)
1113 Description: "In standard mode it intercepts SIGINT and sends a CTRL+C
1114 (0x03) to the target's vtty_con buffer, while in hypervisor mode it
1115 gracefully shuts down the hypervisor which causes the application to
1116 quit."
1117
1118 04-Jul-2006
1119 -----------
1120 - Fixed a stupid bug in mts_cache (phys_page boundary not checked).
1121 - Optimized JIT flushing and insn block allocation.
1122 - Changed the maximum number of translated pages to 2048, which seems to
1123 be a more adequate value.
1124
1125 05-Jul-2006
1126 -----------
1127 - Added an "exec zone" which is a pool of host executable pages. This
1128 zone is limited by default to 64 Mb for Linux/Unix and 16 Mb for Cygwin.
1129 When the zone is fully used, the JIT structures are flushed (removed the
1130 maximum number of translated pages).
1131 Now, there is no need to disable ExecShield or similar systems.
1132 - Added explicit error message when failing to open an ELF file.
1133 - Fixed getopt_long() usage.
1134 - Added CLI option "--exec-area <size>" to define exec zone size for the
1135 default VM.
1136
1137 06-Jul-2006
1138 -----------
1139 - Added "tlbwr" (TLB Write Random) instruction and coprocessor 0 random
1140 register management.
1141 - Added "c7200 set_exec_area" hypervisor command.
1142 - Allowed the hypervisor to run on Windows 2000 machines (ip_listen()
1143 version is now ok for non-rfc2553 systems).
1144
1145 07-Jul-2006
1146 -----------
1147 - Added command line help for "--exec-area" option.
1148 - Updated documentation.

1156 - Added cleanup code for general log file.
1157 - bugfix: memory leak in hypervisor command execution.
1158 - Added logging for hypervisor commands.
1159 - Invalid instructions in delay slots are now properly handled by the JIT
1160 compiler (error message + CPU stop).
1161
1162 13-Jul-2006
1163 -----------
1164 - Added an idle loop detector (--idle-pc CLI option + "Ctrl-] + i" key)
1165 - Added "c7200 set_idle_pc" hypervisor command.
1166
1167 14-Jul-2006
1168 -----------
1169 - Updated documentation.

1181 -----------
1182 - bugfix: no empty mips64_emit_invalid_delay_slot() function for non-JIT
1183 build.
1184 - Added definition for mmap() MAP_ANONYMOUS flag for systems where only
1185 MAP_ANON is defined.
1186 - Accurate Timer IRQ (added --timer-itv parameter for tuning).
1187
1188 18-Jul-2006
1189 -----------
1190 - Fixed inter-pages jumps in delay slots (reported by nula)
1191 - Added a check preventing to run the idle-pc feature when an idle-pc value
1192 is already defined (since it would give biased results).
1193 - bugfix: VTTY list not locked in vtty_create()
1194 - bugfix: ensure the CPU is running before incrementing pending timer IRQs.
1195 - Added a checklist for minimal C7200 hardware components. It checks good
1196 init of ram, rom, nvram and zero devices.
1197
1198 19-Jul-2006
1199 -----------

1206
1207 21-Jul-2006
1208 -----------
1209 - Various code cleanups.
1210 - Added "c7200 set_debug_level" hypervisor command and "--vm-debug" command
1211 line option. Now, by default, less details are printed.
1212 - Fixed a bug with select() on Cygwin platform: before, only 64 FDs
1213 could be used.
1214
1215 24-Jul-2006
1216 -----------
1217 - bugfix: accept_fd was not closed in VTTY module (BTS entry #42)
1218 - bugfix: properly handle CR/LF in configuration files (FR, ATM, ...)
1219 (BTS entry #36)
1220 - bugfix: accept fd not correctly printed in log file.
1221 - Added a mini-parser for hypervisor: allows directory with blanks, ...

1234
1235 26-Jul-2006
1236 -----------
1237 - Added "ethsw clear_mac_addr_table" to clear MAC address table of a
1238 virtual ethernet switch.
1239 - Added "ethsw show_mac_addr_table" to show all MAC addresses learnt by
1240 a virtual ethernet switch.
1241 - Fixed a potential bug with jalr/jr instructions, where the stack is used
1242 to save the return PC. If the instruction in the delay slot returned
1243 directly to the jit main loop (exception,...), the stack would be in
1244 an inconsistent state. This fix is also required for Darwin/x86.
1245
1246 27-Jul-2006
1247 -----------
1248 - Stack alignment for Darwin/x86 in memop functions and unknown opcode
1249 handling.
1250 - The Darwin/x86 build requires -mdynamic-no-pic as compilation option.
1251 - Fixed some inline assembly mistakes with "lock" prefix.
1252 - The Darwin/x86 port seems to be working correctly.
1253 - Fixed the amd64 version of "jr" instruction similarly to the x86 version

1288 state.
1289 - Fixed nmc93c46 EEPROM code to set the data out bit to a high value when
1290 not reading data (was required for C3600 NM EEPROM) + various bug-fixes
1291 and cleanups.
1292
1293 04-Aug-2006
1294 -----------
1295 - C7200: some cleanups in PA function naming.

1350 20-Aug-2006
1351 -----------
1352 - Added code to gen_eth module for Cygwin to prevent WinPCAP from giving
1353 back transmitted packets. It requires WinPCAP 0.4-alpha1 or better.
1354 TODO: need to be tested!
1355
1356 21-Aug-2006
1357 -----------
1358 - Fixed C3660 boot. Trying to understand/discover the hardware.
1359 Environmental monitor should be ok.
1360
1361 24-Aug-2006
1362 -----------

1370
1371 28-Aug-2006
1372 -----------
1373 - C3660: Network Modules are now working! Remaining stuff: OIR.
1374

1382 - Checked WinPCAP fix of 20-Aug-2006: working.
1383 - Added the capability for high priority IRQ (like NetIO IRQ) to break
1384 the idle loop. Great latency improvement with NetIO IRQ.
1385 - C3600: the DUART irq is now higly prioritized. It gives better console
1386 reactivity.
1387
1388 30-Aug-2006
1389 -----------
1390 - Huge performance improvement on dec21140 and am79c971 drivers, by
1391 transmitting up to 16 packets in one TX ring scan pass.
1392 - Added the same to Serial driver (untested).
1393 - Added "unicast limiter" feature to the am79c971 driver, similarly to the
1394 dec21140 driver. Not having this caused the virtual instances to see
1395 unrelated host traffic when using linux_eth/gen_eth NIO and consequently
1396 a bad performance was obtained. Thanks to Greg for noticing that.
1397 - Beginning of rework of PCI subsystem for PCI bridge support.
1398 (Greg noticed that with 12.2T releases, the PCI bus numbering is
1399 different for the C3660).

1402 -----------
1403 - Finished the PCI subsystem rework.
1404 - C7200: Fixed PCI bridge use for midplanes (std: dec21050, vxr: dec21150).

1411
1412 03-Sep-2006
1413 -----------
1414 - Added safety checks to the PCI bus management.
1415 - Added a PLX9060 device (very basic for now).
1416 - Rewritten the PA-POS-OC3 driver to use the new PLX9060 driver.
1417 - Cleanup: removed use of c7200 bay info in drivers (everything uses
1418 PCI for configuration).
1419 - C7200: removed the bay module which contained static definitions of
1420 PCI bus, physical addresses for PA, ... Now everything is handled
1421 dynamically by the PCI subsystem and the remaining drivers (PA-4B,
1422 PA-POS-OC3) have been fixed.
1423 - C3600: removed PCI bus info from the bay module (due to PCI bridge new
1424 code).
1425
1426 04-Sep-2006
1427 -----------
1428 - Fixed some typos in comments.

1437 alteration.
1438 - Hypervisor commands now supports a variable number of parameters.
1439 - bugfix: doing a "sh run" and then pressing "Escape" was causing trouble
1440 to the VTTY (the state machine was in an incorrect state).
1441
1442 06-Sep-2006
1443 -----------
1444 - Removed erroneous special handling of intra-page jumps in delay slots.
1445 (problem with c3640 12.0(7)T IP+ image).
1446
1447 07-Sep-2006
1448 -----------
1449 - C3600: processors ID are now correct.
1450 - Avoid removing the JIT block of the caller with the "cache" instruction.

1466 caused port 0 to be disabled when manipulating other ports.
1467
1468 11-Sep-2006
1469 -----------
1470 - Fixed loop overflow in idle pc computation.
1471 - Added base64 encoding/decoding module from Yannick Le Teigner.
1472 - Added hypervisor commands "vm push_config" and "vm extract_config"
1473 to manage IOS configurations. Extracting to base64 is ok (verified with
1474 a third party decoder:
1475 http://www.opinionatedgeek.com/dotnet/tools/Base64Decode/Default.aspx )
1476 - C3600: NVRAM checksum is now correctly computed.
1477
1478 12-Sep-2006
1479 -----------
1480 - Following a suggestion of Yannick Le Teigner, applied the optimization
1481 principle to PA-A1 card already used in dec21140, ... Latency is clearly
1482 better (on my system, this dropped from about 150ms to 50 ms).
1483
1484 14-Sep-2006
1485 -----------
1486 - Incorrect display of device name in PLX9060 driver.

1496 22-Sep-2006
1497 -----------
1498 - NM-16ESW: interfaces are now up (handles specifically the appropriate
1499 MII register).
1500
1501 23/25-Sep-2006
1502 --------------
1503 - Still continuing on the NM-16ESW (first packets received/transmitted).
1504
1505 26-Sep-2006
1506 -----------
1507 - NM-16ESW: seems to be working! (although there are still a lot of things
1508 to do).
1509
1510 28-Sep-2006
1511 -----------
1512 - Added a hack to allow Ethernet NM to work correctly in 3620/3640
1513 (seen when directly attached to the real network with very few packets
1514 incoming).
1515 - NM-16ESW: proper support for tx ring scatter/gather support.
1516 - NM-16ESW: fixed a bug in ARL insertion.

1541 in general.
1542
1543 05-Oct-2006
1544 -----------
1545 - Fixed bug described in BTS entry #65 (in the case where two virtual
1546 addresses point at the same physical address, the JIT can use
1547 inappropriate block). This was a "silent" bug.
1548
1549 07-Oct-2006
1550 -----------

1578 the CPU.
1579 - Added online setup of idle-pc through the hypervisor command
1580 "vm set_idle_pc_online <vm_name> <cpu_id>".
1581 - Values computed for idle-pc are now stored in the virtual MIPS CPU
1582 and can be known through the hypervisor command
1583 "vm show_idle_pc_prop <vm_name> <cpu_id>".
1584
1585 15-Oct-2006
1586 -----------

1609
1610 22-Oct-2006
1611 -----------

1622
1623 24-Oct-2006
1624 -----------
1625 - C2691: NVRAM config export is working, config import requires more work
1626 (since write operations to flash are not immediate).

1640 signal an interrupt for it on the 2691 platform :(
1641
1642 27-Oct-2006
1643 -----------
1644 - C2691: found how to announce correctly NM presence in slot 1.
1645 - GT96100: finally found how to notify appropriately the network interrupt:
1646 the Serial Cause Register has to be handled.
1647 - C2691: added the glue code to set up GT96100 ethernet ports.
1648 - GT96100: added RX part. Packets are now sucessfully handled.

1665 -----------
1666 - GT96100: added minimal MIB counters.
1667 - Implemented LBA mode for PCMCIA ATA disk devices and fixed data access.
1668 - Changed the default idle sleep time from 50ms to 30ms to avoid timer
1669 IRQ loss and timer drift.
1670 - Added hypervisor command "vm show_timer_drift <vm_instance> <cpu_id>"
1671 to display potential problem with a given idle-pc value.
1672 - C2691: added proper support for IO memory.
1673 - NM-16ESW: generalized code to support multiple platforms.
1674 - C2691: added support for NM-16ESW.
1675
1676 31-Oct-2006
1677 -----------
1678 - C3725: initial support. Hardware very similar to c2691: Cisco rocks!
1679 - C3745: added skeleton.
1680 - C3745: fixed GT96100 address.
1681 - C3745: added PCI bridges.
1682 - C3745: Network Modules are working!
1683 - C3745: CompactFlash working.
1684
1685 01-Nov-2006
1686 -----------
1687 - C3745: finally understood how to handle the system EEPROMs.

1690
1691 02-Nov-2006
1692 -----------
1693 - Added support for "ghost" RAM: instances use a RAM file (previously
1694 created) and use copy-on-write on it. It allows to share common memory
1695 between instances and so less memory is used.
1696
1697 03-Nov-2006
1698 -----------
1699 - Better support for ghost RAM, added hypervisor commands
1700 "vm set_ghost_status" and "vm set_ghost_file".
1701
1702 04-Nov-2006
1703 -----------
1704 - NM-16ESW: fixed incorrect BPDU handling (which caused to add a 2nd
1705 802.1Q tag to BPDU packets) and now 0100.0ccc.cccd is recognized as
1706 a BPDU MAC address (BTS entry #).
1707 - DEC21140: fixed CSR8 handling (missed frame counter), which returned
1708 an undefined value (BTS entry #81).
1709 - Merged a patch from Rostislav Opocensky who added support for C3600
1710 in nvram_export utility.
1711 - Re-enaebled debugging info for NM-16ESW on 2691/3600/37xx.

1721 (config register setting was ignored).
1722 - Added detection of empty NVRAM for 2691/3725/3745 to set the ignore config
1723 flag in the config register (to boot faster).
1724 - C3745: Fixed NVRAM properties.
1725 - C7200/C3600: rewrite of configuration push into NVRAM (can now be done
1726 offline).
1727 - C2691/C3725/C3745: added support for config push into ROM flash
1728 (simulated NVRAM).
1729
1730 07-Nov-2006
1731 -----------
1732 - Modified config export from NVRAM for all platforms (can now be done
1733 offline).

1736 08-Nov-2006
1737 -----------
1738 - Rework of the MTS subsystem (generalization of MTS64 algorithms to MTS32
1739 which was broken).
1740 - Fast memory operations for 32-bit mode.
1741
1742 09-Nov-2006
1743 -----------
