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 |
|
parameter.
