We tried lscpu 2.37.2, and it could also show correct information. So the fix change should be merged during 2.34 to 2.37.
Please help on this issue to backport the fix change to 2.34 for Ubuntu focal. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to util-linux in Ubuntu. https://bugs.launchpad.net/bugs/2041779 Title: lscpu shows wrong L3 Cache size on NVIDIA Orin Nano Status in util-linux package in Ubuntu: New Bug description: For NVIDIA Orin Nano, L3 all cache size is 4M.

Can you please backport the fix change to 2.34 then we can get correct information using default lscpu for Ubuntu 20.04?
