Hello, I installed lttng and lttng modules on NVIDIA Orin.
When using apt install, the results are as follows.

You will need to rebuild your kernel with CONFIG_KPROBES=y, as stated in the error message. This is required from kernel 5.7.0 onwards.

Updated by Michael Jeanson about 2 years ago
The output from '/proc/config.gz' confirms that the running kernel does indeed have CONFIG_KPROBE, the lttng-modules-dkms package uses the kernel headers and config located in '/lib/modules/$(uname -r)/build/', those have to match the running kernel.

make: Leaving directory '/usr/src/linux-headers-5.4.0-131-generic'
According to the above log, it looks like the cause of the problem may be that the kernel headers for this kernel does not seem to be installed. And the header files in the following directory are being used /usr/src/linux-headers-5.4.0-131-generic.
From the image below, there is no linux-headers-5.10.104 in /usr/src.
Is this the cause of the problem? Or do you know the root cause of the above problem
Updated by Michael Jeanson about 2 years ago
There is 2 different issues here, the lttng-modules-dkms will by default only build modules for packaged kernels. In this case the build failure you see in the dkms.log is for the '5.4.0-131-generic' kernel shipped by ubuntu.
The second issue is that you don't seem to have the headers for your '5.10.104' kernel, there is a dangling symlink for the 'source' directory but the headers we are interrested in should be in '/lib/modules/5.10.104/build'. This directory exists but I don't see what its content is.
If you can confirm that the kernel headers are indeed installed, the next step would be to try building lttng-modules from the latest 2.12.x source tarball.

Install lttng-modules with the correct version of the header files.

The kernel headers in '/lib/modules/5.10.104-tegra/build' need to be configured with the same '.config' file as the running kernel.
Updated by liuhonggang liu about 2 years ago
Hello.
I’m running the last kernel available from JetPack5.0.1 Linux for Tegra r35.1, which is a LTS ubuntu 20.04 LTS. Install lttng-modules-2.12.10 from source on this device. I confirm that the kernel headers are indeed installed and CONFIG_KPROBES = y on my system.
1. Does lttng-modules support installation on this system?
2. If installation is supported, can you reproduce the following error
# error "LTTng-modules requires CONFIG_KPROBES on kernels >= 5.7.0"
3. If you do not have the conditions to reproduce, I can support you in every step of analysis and give you feedback on the results of every step.

I downloaded the 5.10.104 kernel sources from Nvidia on this page:
https://developer.nvidia.com/embedded/jetson-linux-r351Then used the defconfig to which I added CONFIG_KPROBES and had no issues building lttng-modules '2.12' and '2.13'.
I'm still convinced your issue is that the headers / kernel sources which you use to build lttng-modules don't match you running kernel.
We do offer professional services at "https://efficios.com", including packaging and deployment, it might be an option for your organisation.
Updated by liuhonggang liu about 2 years ago
We use JETSON AGX ORIN, the .config file shows no problem when flashing, and the kernel compilation and flashing are no problem.
1. Did you modify the kernel before compiling? If so, how did you compile lttng-modules-dkms into the kernel?
2. Have you tested installing lttng-modules-dkms on orin devkit? Is it convenient to show your environment here?
3. How much does it cost via "https://efficios.com"?
4. Would you like to introduce how you used https://developer.nvidia.com/embedded/jetson-linux-r351 to install lttng-module-dkms?
Your answer will give me a great help, looking forward to your answer.
Thank you.

No, I built a kernel from the Nvidia source tarball and then built lttng-modules also from a source tarball.
2. Have you tested installing lttng-modules-dkms on orin devkit? Is it convenient to show your environment here?
No
3. How much does it cost via "https://efficios.com"?
It really depends on the scope of the support you want, you can contact "info@efficios.com".
