The files in ``/proc/sys/abi`` can be used to see and modify
ABI-related settings.
Currently, these files might (depending on your configuration)
show up in ``/proc/sys/kernel``:
.. contents:: :local:
vsyscall32 (x86)
Determines whether the kernels maps a vDSO page into 32-bit processes;
can be set to 1 to enable, or 0 to disable. Defaults to enabled if
``CONFIG_COMPAT_VDSO`` is set, disabled otherwise.
This controls the same setting as the ``vdso32`` kernel boot
