How do you determine if in secure boot mode from a static driver/module?

[David F.]

Hi,

Subject says it all.  Given a static driver linked in to the kernel,
what is the best way for it to determine if the system has booted with
secure boot enabled?   It looks like if I could access the bootparams
struct there is a "secure_boot" member set on kernel startup from EFI
handover.

Thanks.
