modprobe

========

This gives the full path of the modprobe command which the kernel will

use to load modules. This can be used to debug module loading

requests::

The full path to the usermode helper for autoloading kernel modules,

by default "/sbin/modprobe".  This binary is executed when the kernel

requests a module.  For example, if userspace passes an unknown

filesystem type to mount(), then the kernel will automatically request

the corresponding filesystem module by executing this usermode helper.

This usermode helper should insert the needed module into the kernel.

This sysctl only affects module autoloading.  It has no effect on the

ability to explicitly insert modules.

This sysctl can be used to debug module loading requests::

    echo '#! /bin/sh' > /tmp/modprobe

    echo 'echo "$@" >> /tmp/modprobe.log' >> /tmp/modprobe

    chmod a+x /tmp/modprobe

    echo /tmp/modprobe > /proc/sys/kernel/modprobe

This only applies when the *kernel* is requesting that the module be

loaded; it won't have any effect if the module is being loaded

explicitly using ``modprobe`` from userspace.

Alternatively, if this sysctl is set to the empty string, then module

autoloading is completely disabled.  The kernel will not try to

execute a usermode helper at all, nor will it call the

kernel_module_request LSM hook.

If CONFIG_STATIC_USERMODEHELPER=y is set in the kernel configuration,

then the configured static usermode helper overrides this sysctl,

except that the empty string is still accepted to completely disable

module autoloading as described above.

modules_disabled

================

     successful IPC object allocation. If an IPC object allocation syscall

     fails, it is undefined if the value remains unmodified or is reset to -1.

nmi_watchdog

============

Version 1 of the Activity Monitors architecture implements a counter group

of four fixed and architecturally defined 64-bit event counters.

- CPU cycle counter: increments at the frequency of the CPU.

- Constant counter: increments at the fixed frequency of the system

  clock.

Firmware (code running at higher exception levels, e.g. arm-tf) support is

needed to:

- Enable access for lower exception levels (EL2 and EL1) to the AMU

  registers.

- Enable the counters. If not enabled these will read as 0.

The fixed counters of AMUv1 are accessible though the following system

register definitions:

- SYS_AMEVCNTR0_CORE_EL0

- SYS_AMEVCNTR0_CONST_EL0

- SYS_AMEVCNTR0_INST_RET_EL0

----------------

Currently, access from userspace to the AMU registers is disabled due to:

- Security reasons: they might expose information about code executed in

  secure mode.

- Purpose: AMU counters are intended for system management use.

Currently, access from userspace (EL0) and kernelspace (EL1) on the KVM

guest side is disabled due to:

- Security reasons: they might expose information about code executed

  by other guests or the host.

	Use ktime_get() or ktime_get_ts64() instead.

.. c:function:: struct timeval do_gettimeofday( void )

		struct timespec getnstimeofday( void )

		struct timespec64 getnstimeofday64( void )

.. c:function:: void do_gettimeofday( struct timeval * )

		void getnstimeofday( struct timespec * )

		void getnstimeofday64( struct timespec64 * )

		void ktime_get_real_ts( struct timespec * )

	ktime_get_real_ts64() is a direct replacement, but consider using
