Vagrant Cascadian observed that only 1 CPU is activated on the Jetson TX1 development kit. I can confirm this with mainline Linux and u-boot from mainline (2016.11) or L4T (2016.03-00633-g3ef9cdb from R23.2). I see the following in dmesg: [ 0.000000] /cpus/cpu@1: missing enable-method property [ 0.000000] /cpus/cpu@2: missing enable-method property [ 0.000000] /cpus/cpu@3: missing enable-method property [ 0.052643] Tegra Revision: A02 SKU: 23 CPU Process: 0 SoC Process: -22 [ 0.053149] EFI services will not be available.
