config MODE_TT
bool "Tracing thread support"
default y
help
This option controls whether tracing thread support is compiled
into UML. Normally, this should be set to Y. If you intend to
use only skas mode (and the host has the skas patch applied to it),
then it is OK to say N here.
config STATIC_LINK
bool "Force a static link"
default n
depends on !MODE_TT
help
If CONFIG_MODE_TT is disabled, then this option gives you the ability
to force a static link of UML. Normally, if only skas mode is built
in to UML, it will be linked as a shared binary. This is inconvenient
for use in a chroot jail. So, if you intend to run UML inside a
chroot, and you disable CONFIG_MODE_TT, you probably want to say Y
here.
config MODE_SKAS
bool "Separate Kernel Address Space support"
default y
help
This option controls whether skas (separate kernel address space)
support is compiled in. If you have applied the skas patch to the
host, then you certainly want to say Y here (and consider saying N
to CONFIG_MODE_TT). Otherwise, it is safe to say Y. Disabling this
option will shrink the UML binary slightly.
