question on radisys ENP-2505
by Josh Fryman 12 Apr '02

12 Apr '02

hi all, we've been tinkering with our ENP-2505. on pg4 of the hw ref manual (nov 2001), it documents two different modes of operating - hosted and hostless - controlled by SW0201 bit 1. however, in both contexts, it discusses how the ENP will interact with the PC host via the PCI bus. what is meant by hostless environment? is this a standalone mode where the ENP should be self-sustaining in a non-PC environment (eg, the old EVB chassis)? or does it mean something else? we'd like to stick an ENP into an old chassis... if possible. thanks, -josh

Hi, I am trying to run the Diagnostics code on ixbus given by Intel.MY hardware has got an IXF1002 and I want to make sure that I dont have any problems with the IXbus. For this I complied the code provided by Intel and tried to run it on Cygmon.I have several issues with the code. 1) when I run the test I can see the transmit code working(transmitfp.uc file) also I am able to read the FRDY1/2 bits set in the RCV_RDY_CNT register,which indicates that the data is available at the MAC ports 0/1 of the IXF1002. 2)But I observed that the receive scheduler never issues any receive requests.It always executes upto the Small_loop# loop in the rcvschedfp.uc file. Now I want to know whether the receive scheduler implemented in the rcvschedfp.uc really works.IF not what all changes do I need to make. The code no where mentions the values of the XMIT_RDY_CNTL and the RDYBUS_SYNCH_COUNT_DEFAULT. Also its not clear which fast port mode is being used (explicit/single thread). Any INTEL GUYS outthere ...help me out. Thanks __________________________________________________ Do You Yahoo!? Yahoo! Tax Center - online filing with TurboTax http://taxes.yahoo.com/

RE: [ixp1200] SDK 2 ACE sample simulation
by Naik, Uday 11 Apr '02

Yes. This was intentional. In the microACE model, the ACE component on the SA core is critical in that it configures the data structures needed by the microcode, patches symbols, handles exception packets, exports an API for user applications etc. Without the core component the functionality of the microACE is quite incomplete. While it is possible to write ind files to get the microcode running, it is relatively difficult to test/use all the features without the core component. It is also easy to change and misconfigure something using the ind files. For this reason, the ACE samples were extensively QA'ed on hardware only. We do ship the workbench projects running on hardware. All customers of the SDK were supposed to get associated reference hardware. So not shipping the ind files was not considered an issue.

Therefore, one can not use the workbench for simulation and evaluation of these samples. Is this intended? Thanks, Mirko University of Technology Dresden, Germany

Re: [ixp1200] Large packets on the IXP
by Michael E. Kounavis 09 Apr '02

Abhijeet, The fact that you have buffer overflows at so low incoming bit rates may be an indication that your IP forwarding code does not serve packets "quickly enough" so that each packet is being proceesed during a period of time that is larger than the time it is supposed to spend in a microengine. Could be a problem with your code. Or it could be a by-product of bad thread scheduling. Check when your threads swap context. I suggest to test your code using the Developer Workbench carefully. -- Michael

mounting NFS
by Sundararaman Shiva 02 Apr '02

Hi, I am trying to mount NFS on a directory in linux running on the strong arm. The IXP1200 is connected to the PCI of the host running linux. I checked the /etc/exports and /etc/hosts files they seem to be configured fine. I also checked to see if the server on the host machine is running nfs and disabled the firewall. It seems to be working. THe host and card and pinging with each other. But when I try to mount the NFS directory it is not working. When I dumped the packets from pci on the host, I see the target saying the host is unreachable. Any suggestion? Thanks, shiva __________________________________________________ Do You Yahoo!? Yahoo!
