Hello,
I noticed that Intel, when describing its gate formats, doesn't tell you how to set the gate so that it references a descriptor in the global descriptor table or local descriptor table.
Segment selectors when loaded into segment registers have a one bit field that signifies whether the selector references the GDT or LDT.
But I don't see any such field in gates.
There are some fields in the gates that aren't explained (at least not yet in the text).
But other than that, I don't see any possibility for how to tell whether the gate references the GDT or LDT.
Any thoughts?
