You might want to add which kernel this is (release version and if downloaded from a particular L4T release or source_sync tag).


It’s the public source downloadable from the 34.1.1 BSP release webpage.


Thanks for sharing the patch. Please also share what issue you have seen. And do you see error prints in dmesg? Would like to have more information and we can check with our teams.


I did not boot it yet.

I ported the nvgpu parts to kernel 5.15 and noticed some compilation bugs when building.

Debugging those showed these 3 errors.

The strangest one actually is the missing var which is being assigned.

Doing a simple grep on the full tree as downloaded showed that it does not exist.
So I wonder how this one got through :)

Could you try default release? It is 5.10 by default and we suggest try this first. To make sure you can boot up successfully with default release.
