This is fairly ridiculous to be honest. If you’re going to track an LTS kernel at least keep it up to date with upstream patches. Mainline’s 4.9 is now 4.9.247 ! and includes almost a year !!! of security and bug fixes now which your kernel is lacking. If you don’t address this then your platform is as good as defunct.
Please see this post - the L4T kernel is updated with each JetPack release including bug fixes, security patches, backports from upstream, ect.
The security bulletins are posted to NVIDIA Product Security | NVIDIA
Additional top-fixed issues are included with the L4T Release Notes.
You can also see the git logs here for patches and backports: nv-tegra.nvidia Code Review - linux-4.9.git/summary
Can you give us more information on which version of kernel we can expect for the second half of 2021? The roadmap link doesn’t say about this. We need this info to plan for drivers and device upgrades.
Any updates on this? Which kernel will you upgrade to?
We are building a battery-powered Jetson TX2-based device which is heavily dependant on WiFi connectivity. Roaming with wpa_supplicant is not exactly issue-free and we would like to replace it with iwd. However, iwd requires linux 4.20+.
Like others that have already replied to this post, we are also interested in what kernel is planned for “2H2021CY”. This is an important feature that we will be using to make our compute platform selection.
Hi! as Announcing Jetson TX2 NX states that jetpack 4.6 is expected to be released in June, can you share what will be the linux kernel version on this release?
Is there information for Kernel 5.x update for tegra for Nano t210 platform.
While implemented applications and libraries of jetpack L4T are suitable on 4GB ram, Kernels >5.0 are a big improvement for compressed ram page swapping.
Even sources for dkms can avoid too much constraint with needed driver modules for actively maintained and supported Kernel’s.
Can you provide an overview, what would not be functional with a booting to OS Kernel 5.x version (considering Jetpack L4T)?
At this point we need Support outside of Ubuntu
Being limited to Ubuntu 18.04 or 20.04 the libraries in the repositories in certain cases is a pain in the ass to compile more recent versions for example QT 5.15 or QT 6.
If there was some way to run aarchlinux it would be much better for development there you find the latest versions without much trouble and you don’t waste time compiling.
There’s some support in armbian with the latest mainline kernel (but no real GPU support, limited to nouveau).
I know it I have a sdcard with armbian with kernel 5.10 with debian for openmediavault (NAS + Docker manager)
But on the other hand clear when losing vulkan and opengl 4.6 required by some games.
Also the problem of libraries also suffers from the debian/armbian model (Well Ubuntu drinks from that)
Rolling release on aarchlinux support makes it much easier for developers to have the latest version of anything without spending hours compiling or praying that you have all the dependencies to compile any current application.
Many developers are abandoning Ubuntu and Debian because of this “They take time to update” the necessary libraries to compile the latest versions of many apps.
Yeah, lack of GPU support is the main issue for me using 5.10 (or other mainline kernel). Hopefully we’ll see it coming JP 5.0 preview (pretty sure that the driver will be common between Nano & Xavier).
