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 CROSS_COMPILE_COMPAT_VDSO
string "32 bit Toolchain prefix for compat vDSO"
default ""
depends on GENERIC_COMPAT_VDSO
help
Defines the cross-compiler prefix for compiling compat vDSO.
If a 64 bit compiler (i.e. x86_64) can compile the VDSO for
32 bit, it does not need to define this parameter.
