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.
