3 config HAVE_GENERIC_VDSO
8 config GENERIC_GETTIMEOFDAY
11 This is a generic implementation of gettimeofday vdso.
12 Each architecture that enables this feature has to
13 provide the fallback implementation.
15 config GENERIC_VDSO_32
17 depends on GENERIC_GETTIMEOFDAY && !64BIT
19 This config option helps to avoid possible performance issues
20 in 32 bit only architectures.
22 config GENERIC_COMPAT_VDSO
25 This config option enables the compat VDSO layer.
27 config GENERIC_VDSO_TIME_NS
30 Selected by architectures which support time namespaces in the
