It would be really difficult to find out what went wrong without enough log information.
Is it possible to send the full log (right from boot) along with iperf running info in the log? expecting to see some useful information there to continue debugging
ooh do you mean you need the dmesg logs? I’ve attached it bellow. One important thing today I upgrade one of our nodes to 24.2, I thought the bugs are fixed and now when I run iperf the system get rebooted :O

looks like WiFi is active when iperf is run. Some prints in the crash log are from WiFi driver as well.
To isolate the issue, can you please WiFi and try once? (i.e. the only network interface for system to use would be the one added by 10Gigabit ethernet driver)
deleted
I found this is happening whenever I use the 10G interface:

Are you not using the upstreamed driver for Tehuti card?
I tried to look for the code (pasted by you above) but couldn’t.
you can find the drivers code from here:
Can you please provide the value of ‘page_size’ after this line gets executed?
so I added:
ERR(“REZA_page_size:%d, %d\n”,page_size, LUXOR__MAX_PAGE_SIZE);
and I got:
- the bandwidth reduced from 6G to 1.x which I think because of the extra I/O it has to do.
- memory utilization like always goes up but after it eat all the memory the page_size set to Luxor_max_page_size and iperf failed.

I have good news, I find the solution is to comment out “#define USE_PAGED_BUFFERS 1” in tn40.h to not use page buffers and the drivers is working without problem on Ubuntu 14.04 and kernel 3.10.96.
However, as I mentioned before when I use the latest Jetpack 2.3 with Ubuntu 16.04 and kernel 3.10.96 with the driver, system crashes and I have to reboot. This problem still exist even with the modified driver. I mean 16.04 crashes with both original and modified drivers. Now the question is what has changed from 14.04 to 16.04 and why its not working on 16.04. Anyone has any idea? Because of the reboot I don’t see anything in dmesg and I looked at /var/log/syslog and I couldn’t find anything why OS crashes.
Do you have a serial console cable? This would probably see things not making it into logs. See:
[url]http://elinux.org/Jetson/TX1_Serial_Console[/url]
Sorry it took some time until I buy the cables. Here I got the logs:

I remember you mentioned this patch once but It wasn’t enabled because we are using 24.1.
I double checked right now, we are using 24.2.1 but still there is no dma-mapping.c on our tegras.
but your log in #32 shows that the panic happened in arm_coherent_iommu_map_page(), Can you tell me the location of that function if not from dma-mapping.c file?
I searched everywhere for it and the only place it exists is in System.map in /usr/src/linux-headers-3.10.96-tegra directory. Can the panic be for OS not finding the function?
It looks to me that you might be searching on target. Please search for it in the kernel source code ( you might be having it in an x86 system probably).
I found figure it out. I couldn’t find the kernel source code on our host machine, there was only the binaries. But I used the instructions from link below to modify the source code:
one thing I want to note is the link above work on the source code from this link:
http://developer.download.nvidia.com/embedded/L4T/[b]r24_Release_v2.0[/b]/BSP/sources.tbz2
As it shows it gets the source code from 24.2 but as I remember our node has revision 24.2.1.
I tried to find the source from 24.2.1 but I couldn’t. is it even public?
Now I explain what happened after the kernel setup. So I followed the instructions and applied the changes to dma-mapping.c and recompiled the kernel. The new kernel doesn’t have any problem in terms of rebooting or error except the 10G bandwidth I’m getting from the network card is 1/5 of what I’m getting on the node with ubuntu 14.04 (release 24.1 and kernel 3.10.96)
Because of performance issues we like to work with the latest jetpack (because we observed a huge performance boost coming from it).
I have the following the question:
- if the problem is in the kernel source code, I don’t understand why kernel 3.10.96 has no problem with 24.1 and it has with 24.2.1
- Also if the latest release is 24.2.1 how can I get the latest kernel source code? it seems I got the 24.2; is it public? can you give it me?
- Any idea why I lost 4/5 of bandwidth?
I think 24.2.1 shows under JetPack, while 24.2 (meaning 24.2.0) is from the download page under direct file download. Perhaps the R24.2 downloads page can be updated to add the JetPack version of individual packages (I don’t know what the differences are, this difference might be just the files from the apply_binaries.sh step, or to the sample rootfs in general).
I’m still looking for answers. I have two configurations
- R24.1 with kernel 3.10.96 which works fine. I can’t use this one because R24.2 has performance boost on other libraries.
- R24.2.1 with kernel 3.10.96 from 24.2 which I modified the dma-mapping.c. This one gives 1/5 bandwidth compare to the working node (1). I was wondering what can I do? when kernel source code for 24.2.1 become available for download? maybe that can fix it? I don’t see any error otherwise, I posted it. My main problem is bandwidth is not as expected compare to node 1 explained above.
I would appreciate any help.
