Wydana została wersja 0.2.7-RC2.
Hello all,
The 0.2.7-RC2 release is available. It is mainly a bug-fix/optimization release, without new features.
Bug fixes:
MIPS JIT: fixed a problem of jump in delay slots (occuring with a “forward” jump). This caused a malfunction for C7200-IO-2FE and C7200-IO-GE-E cards.
Cisco 2600: fixed a bug in DMA handling which caused incorrect writes out of DPRAM memory (and lead to image crashes).
Fixed JIT instruction tables, which caused a higher startup delay of the emulator on AMD64 platforms.
Serial interfaces (NM-4T, PA-4T, PA-8T): now allows MTU up to 18000 bytes.
NM-16ESW: filter CDP specifically to not propagate frames to all ports.
NM-4E: now works correctly on Cisco 2600 platforms.
Fixed source build (in NetIO filters) when PCAP is lacking.
Fixed source build for non-JIT platforms.
Optimizations:
Network interrupt handling was rewritten. Now these IRQs are managed on a per-slot/port basis, this also leads to a more accurate network device emulation.
PowerPC: optimizations in Condition Register (CR) handling.
JIT (MIPS, PowerPC): optimizations in jumps between different pages, allowing an higher performance. However, it may require to recompute idle-pc values. Greg will provide an “oldidle” compatibility option in Dynagen 0.9.1 for people who don’t want to change these values now.
JIT (MIPS, PowerPC): added a cache for instruction tables (as disk files), allowing a faster startup. If these files are deleted, they are rebuilt dynamically.

chris pisze:Hello all,

The 0.2.7-RC3 release is available, as a bug-fix/optimization release.

Bug fixes:

* Compressed IOS images for MIPS platforms were not working anymore. This is now fixed. You still have to uncompress images for the 2600 platform.
* Cisco 3725 - slot 2 problem : slot 2 was not usable in RC2 leading to a lockup.

Optimizations:

* New PowerPC JIT compiler which allows to add some optimizations for the generated code: register allocation, peephole optimizations, more efficient Condition Register (CR) handling.

W koncu udalo mi sie zapostowac na czas :)

Po tescie 0.2.7-RC3 wrocilem do 0.2.7-RC2 ze wzgledu na opcje idlepc, ktora mimo zastosowania oldidle nie dziala z moja dotychczasowa wartoscia a szukac kolejnej tak dobrej jest bez sensu przynajmniej narazie, kolejna rzecz to taka ze mialem przy tej wersji zwisy zarowno w wersji binarnej jak i samodzielnie kompilowanej, mowie tu o architekurze x86_64 dla AMD. Moze to problem mojego OS ale od dwich dni na starej wersji nic sie nie dzieje, a RC3 praktycznie dla mnie wnosi tak niesitotne zmiany ze zotaje przy RC2 :)

chris pisze:0.2.7 final release
May 26th, 2007

Hello all,

The 0.2.7 final release is available. Compared to 0.2.7-RC3, it contains the following fix:

* Cisco 2691/3725/3745: high packet loss on integrated FastEthernet ports when they were simultaneously enabled (incorrect interrupt clearing in TX ring handling, please see BTS entry #171 for details).

The development will continue with 0.2.8-RC1 to be published soon.

Pojawil sie niedawno nowszy dynagen'ik :wink: w wersji 0.9.3 - znow kilka bugow mniej :wink:

http://sourceforge.net/project/showfile ... _id=160317

Kod: Zaznacz cały

Version 0.9.3 changlog:
* No longer prints a warning for unused switchports
* Added "MAC" option to set base MAC address of a router. See all_config_options.txt for usage.
* Eliminated unnecessary Leopard-2FE insertion on 3660s resulting in "a NM already exists in slot 0" warnings from Dynamips.
* Fix bug that caused crash when trying to capture packets on an unconnected interface
* Dynamips temp files are now written to the user's temp dir rather than \Program Files\Dynamips. Might make it work better under Vista.
* Dynagen allows POS to frame-relay switch connections. But there seems to be a bug in dynamips 0.2.7 that prevents it from functioning.
* Console entries in dynagen.ini for use with iTerm on OS X and SecureCRT on Windows. The SecureCRT one is a little glitchy but generally works.
* Entering "no ?" caused a crash
* Including a new Network Device list script for Windows that includes interface descriptions in the output contributed by Volker Semken.

0.2.8-RC1 release - Introduction of Cisco 1700 platform and WICs
from Cisco 7200 Simulator by chris

Hello all,

The 0.2.8-RC1 release is available. It requires a Dynagen upgrade since the hypervisor control protocol has been modified. The new Dynagen release will be published by Greg soon.

New features:

    * Support of the Cisco 1700 platforms, with WIC-1T, WIC-2T and WIC-1ENET cards (as for the 2600, the images need to be uncompressed before use).
    * Support of WIC-1T and WIC-2T for the 2600 (2 WIC slots), 2691, 3725 and 3745 (3 WIC slots) platforms.
    * Support of NM-NAM and NM-CIDS interfaces BUT this not means that you can use them out of the box. It means that you can connect your virtual routers to a VMWare, QEMU, … virtual PC running the NM-CIDS/NM-NAM code. I don’t provide a method to do this, but you can take inspiration here: http://7200emu.hacki.at/viewtopic.php?t=3095. If someone wants to document how to setup this, he/she is welcome.
    * Plugin system (not documented yet) that allows to dynamically load new platforms. It is mainly for coding tests (it avoids to modify the dynamips core with temporary code).

Optimizations / Bug-fixes:

    * New generic card framework to reduce the code specific to each platform (it is transparent to users, and was required for WIC support) ;
    * Fixed JIT compiler for PowerPC and MIPS platforms on MacOS X (stack alignment) ;
    * Fixed JIT compiler for PowerPC on 64-bit Linux platform (incorrect “bctr” instruction) ;
    * Added ISL support for NM-1FE-TX card ;
    * Fixed the Serial cards (NM-4T, PA-4T, PA-8T, PA-POS-OC3, WICs) to handle correctly CRC stuff. Now, you can interconnect them to the virtual Frame-relay switches.

Important note: The use of WIC cards is a bit complicated without Dynagen, so I strongly recommend to use it to mask the gory details.

Kod: Zaznacz cały

The 0.2.8-RC2 release is available. It’s mainly a bug fix release that requires no Dynagen upgrade (except for the ATM/Ethernet bridge).

New feature:

    * Ethernet/ATM bridge, conforming to the RFC1483 (bridged mode). I added this because I’ve this kind of devices on my network (xDSL modem). It will require a Dynagen upgrade to be usable.

Bug-fixes:

    * Fixed a PowerPC JIT bug that caused crashes on some 2600 images and prevented OSPF to work correctly on this platform ;
    * Fixed handling of CRC for WIC slots on 2691/3725/3745 ;
    * Fixed a bootflash malfunction occuring on 3600/7200 platforms ;
    * Added TCP keepalives for VTTY connections (ie console and aux ports) ;
    * Added ISL support for 2691/3725/3745 on-board Ethernet ports.
