sgx disabled by bios

This is a newer warning due to a kernel upgrade.

It allows the linux kernel to interact with CPU security features developed by intel.

The message does not harm anything

You can either:

1. ignore it
2. make a change in the bios to enable the feature.
   1. the cpu may be capable and the bios not.
   2. If you can't find the "switch" in the bios then:
      1. Your motherboard cannot use sgx
      2. Your BIOS is too old.
   3. If after all you determine your hardware cannot use sgx then you can hide it
3. add nosgx as a boot parameter.
   1. In the file /etc/default/grub you add nosgx in the follwoing section
      1. GRUB_CMDLINE_LINUX_DEFAULT="quiet splash nosgx"
   2. sudo update-grub
   3. reboot and you will no longer see the error message.
