Query abt Interrupt handling on IXP1200!!
by param 27 Dec '01

27 Dec '01

Hi there, I did come across abt this IXP1200 mailing list thru websearch. As am new to this area, please do make me sense abt the usage of Interrupts on SA (Strong Arm) side from uEngine. Query : For interrupting a praticular thread in the uEngine from SA, am using INTER_THD_SIG register : *((unsigned int*) (0xB004 01C0))=thd_id // thd_id range : 0 to 23 Afore mentioned C statement would interrupt a thread in the uEngine based on thd_id. Where as in other case, Interrupting SA from uEgine, am not sure abt making use of IREG ... I would appreciate if some one make me sense in accomplishing the following required task. 1. Interrupting SA from uEngine (by IREG) 2. Capturing interrupt at SA which has been asserted by uEngine 3. Serving the Interrupt by making use of vector table, handler & etc... Sample snippet would be greatly appreciated for the afore mentioned request. Thanks & Kindest Regards Param

SDRAM Packet address on BV cards...
by Austen McDonald 20 Dec '01

The entry SDRAM_PACKET_BASE is gone from asm/arch-ixp1200/hardware.h---what is the address in linux that corresponds to the uE sdram addr 0? Austen McDonald austen(a)cc.gatech.edu God does not care about our mathematical difficulties. He integrates empirically. -- Albert Einstein

Bugs in octmac.c documentation?
by Austen McDonald 20 Dec '01

20 Dec '01

In ixasdk/src/microace/aces/interface_ace/source/driver/octdrv/octmac.c it says that the default names for the devices in /dev are octMac0,...octMac7 but the README file says mac0...mac7. I changed my code to say mac--will this affect anything (like the interface aces)? Austen McDonald austen(a)cc.gatech.edu God does not care about our mathematical difficulties.

IXP1200 for TCP termination
by Vishal Anand 19 Dec '01

19 Dec '01

Hi, We have 2 IXP12EB evaluation kit for the IXP1200 processor. Was curious if anybody has ever done a feasibility study for doing TCP termination on the IXP. Theoretically it would seem that the Micro engines are an ideal choice for executing the TCP Fast Path code, while the ARM could run the Slow Path. Would appreciate any feedback if somebody did any work in this direction.

The PciDg Driver's problem
by Victor 13 Dec '01

13 Dec '01

Hi, Dirk How are you doing? I just tested some program on the StrongARM, which transfer the packets between the uEngine and the Host PC. But I found it seems the PciDg module( the Pseudo Network Driver between Host and StrongARM) will lost packets in the transmission. I tested my program on the real network driver, it works fine. It only lost packets on PciDg driver. So do you have any infomation about this problem? I read some source code of the PciDg, but can't figure out the problem yet. Have anyone encountered this problem before? Please give some advices. Thank you very much. Victor

RE: [ixp1200] IXP Simulator Query - passage of packets to Microen gines
by Heaton, Eric D 13 Dec '01

13 Dec '01

Murali, You're correct, there are several ways to simulate network traffic using the Transactor (the IXP1200 simulator). The easiest way is to get the IX Bus Device Simulator up and running. You can find information about this tool in the IXP1200 Developer Tools User's Guide in sections 2.11.19-2.11.22. This feature of the Developer Workbench will allow you to simulate with custom Ethernet or ATM cells, though beyond that, you will have to create a "Network Traffic DLL", which is like a foreign model, but for the specific purpose of putting traffic on the IX Bus. More information on the Network Traffic DLL can be found section 2.11.21 of this same document and an simple code example can be found in the <IXP1200_INSTALL>\WIN32DevTools\Samples\NetworkTraffic directory.

The issue is sending packets to the microengines. As far as I know there are 2 ways of passing packets to the microengines a) Using the IX Bus which comes with the simulator. b) Passing packets from outside the Workbench ( Foreign Model ). I am sucessful in passing packets from the IX Bus, but do not have any idea of sending packets from outside the Workbench ( i.e. from the network ) so that I can manipulate the packets going to the IXP. I think this can be achieved by creation of some DLL's on Windows ( as specified in the manual ) which can be linked to the Simulator. Can any one out there give me some guidance of how to generate these DLL's and the code ?? Or if you already have some sample code which works this way, can you pass it on to me ?? The idea is to send and receive packets from the network (another m/c) to the Simulator. If these is any other method by which we can achieve this, pls specify. Thanks, Regards, -Murali IISc.

Administration: Updated Info
by Scott C. Karlin 11 Dec '01

11 Dec '01

I have updated the "info" file for the mailing list (see below). This is the file which is sent to new subscribers to the list. We originally established this list to link the CS and EE departments of the schools participating in Intel's IXA University Program. One particular project which grew out of this program is the VERA work being done at Princeton. Because we are getting requests for more information from people outside of academia, we have decided to expand the membership of the list and to explicitly add VERA as a discussion topic for the list. In addition to expanding the scope, we have made a few additional changes to the mailing list, including: * We've added reminders that this is not an Intel support list and that one should not post proprietary information. * We have disabled the "who" command. This is to prevent anyone from getting a list of subscribers. Scott Karlin OVERVIEW -------- The purpose of this list is to facilitate discussion on the topics of: (1) the IXP1200 Network Processor including its Ethernet Evaluation System, and (2) Princeton's VERA software. See http://www.cs.princeton.edu/nsg/vera/ This list is not sponsored by Intel and is not a substitute for Intel technical support. POSTING MESSAGES ---------------- To send mail to the people on the list, send your ASCII message (not HTML) to ixp1200(a)cs.princeton.edu Note that this list has been setup so that replies go to the entire list. This is to encourage discussion on the list. GUIDELINES ---------- While informative announcements of products or services that benefit most subscribers are allowed, blatant commercial advertising is not. Please do not clutter the archive with HTML messages or attachments. Use plain ASCII text only. (Place code, papers, etc., on a WWW or FTP site and provide a URL reference instead.) This is an "open" discussion forum in the sense that proprietary information should not be posted to the list. Note that this is a "closed" discussion forum in the sense that we will continue to manually approve submission requests and that we retain the right to unsubscribe abusers of the list. UNSUBSCRIBING ------------- See "unsubscribe" in the COMMANDS section below. ARCHIVE ------- All postings to this list are archived by month into files having extensions which represent the year and month of the archives. See "index" and "get" in the COMMANDS section below for access. COMMANDS -------- Majordomo handles the ixp1200 mailing list. To "execute" a command, send mail to majordomo(a)cs.princeton.edu (NOT ixp1200(a)cs.princeton.edu) Include the command in the *body* of the message (the subject line is ignored and may be blank). Commands include: unsubscribe ixp1200 remove yourself from this list index ixp1200 get a list of available archive files get ixp1200 <filename> retrieve an archive file. info ixp1200 get the most current version of this message (works only if you are on the list) subscribe ixp1200 request to be added to this list (must be approved by the list admin) help general help from Majordomo Note that the "who" command has been disabled. ADMINSTRATOR ------------ If you have administrative questions or comments about the list, send them to ixp1200-request(a)cs.princeton.edu LAST UPDATED ------------ November 27, 2001

We are pleased to announce the release of version 1.0 of LibIXPRouter, a library of code for the StrongARM and microEngines which turn the IXP1200 into a router. The software is available at http://www.cs.princeton.edu/nsg/vera. Please feel free to post any questions. Warning: this is a 1.0 release and is slightly buggy for some cases. Read the README file. Also available are two applications which demonstrate how to use the library. Zuki -- Yitzchak Gottlieb zuki(a)CS.Princeton.EDU
