config HAVE_GENERIC_VDSO
bool
if HAVE_GENERIC_VDSO
config GENERIC_GETTIMEOFDAY
bool
help
This is a generic implementation of gettimeofday vdso.
Each architecture that enables this feature has to
provide the fallback implementation.
config GENERIC_VDSO_32
bool
depends on GENERIC_GETTIMEOFDAY && !64BIT
help
This config option helps to avoid possible performance issues
in 32 bit only architectures.
config GENERIC_COMPAT_VDSO
bool
help
This config option enables the compat VDSO layer.
config GENERIC_VDSO_TIME_NS
bool
help
Selected by architectures which support time namespaces in the
VDSO
config GENERIC_VDSO_OVERFLOW_PROTECT
bool
help
Select to add multiplication overflow protection to the VDSO
time getter functions for the price of an extra conditional
in the hotpath.
endif
config VDSO_GETRANDOM
bool
help
Selected by architectures that support vDSO getrandom().
config GENERIC_VDSO_DATA_STORE
bool
help
Selected by architectures that use the generic vDSO data store.
