Drive AGX Only 7 cores in HTOP and LSCPU

Quick question about the Drive AGX.

Currently doing some benchmarks, and just noticed that I only have access to 7 of the NVIDIA Carmel ARM64 cores, instead of the advertised 8. Just wanted to know if something is wrong on our end, or if there’s anything I can do to increase it to 8.

Dear @jason.wu2,
It is normal. One core is reserved for hypervisor. You can not increase it to 8 cores. Please check DRIVE OS Linux for more details.
