CONFIG_X86_ENABLE_TSS

(No prompt – not directly user assignable.)

Type: bool

Help

This hidden option enables defining a Task State Segment (TSS) for
kernel execution. This is needed to handle double-faults or
do privilege elevation. It also defines a special TSS and handler
for correctly handling double-fault exceptions, instead of just
letting the system triple-fault and reset.

Direct dependencies

!X86_64 && X86

(Includes any dependencies from ifs and menus.)

Defaults

No defaults. Implicitly defaults to n.
