WSMT is as an attestation to the OS that the platform won't
modify memory outside of pre-defined areas.
If a platform has WSMT enabled in BIOS setup, SMM calls through
dcdbas will fail. The only way to access platform data in these
instances is through the WMI SMBIOS calling interface.

It's important for the driver to provide a R/W ioctl to ensure that
two competing userspace processes don't race to provide or read each

This userspace character device will be used to perform SMBIOS calls
from any applications.
It provides an ioctl that will allow passing the WMI ca
