  6         bool "Enable the Anonymous Shared Memory Subsystem"
  7         default n
  8         depends on SHMEM
  9         ---help---
 10           The ashmem subsystem is a new shared memory allocator, similar to
 11           POSIX SHM but with different behavior and sporting a simpler
 12           file-based API.
 13 
 14           It is, in theory, a good memory allocator for low-memory devices,
 15           because it can discard shared memory units when under memory pressure.

 25         ---help---
 26           Unlike generic gpio is to allow programs to access and manipulate gpio
 27           registers from user space, timed output/gpio is a system to allow changing
 28           a gpio pin and restore it automatically after a specified timeout.

 30 config ANDROID_LOW_MEMORY_KILLER
 31         bool "Android Low Memory Killer"
 32         ---help---
 33           Registers processes to be killed when low memory conditions, this is useful
 34           as there is no particular swap space on android.
 35 
 36           The registered process will kills according to the priorities in android init
 37           scripts (/init.rc), and it defines priority values with minimum free memory size
 38           for each priority.

 45         ---help---
 46           This option enables the framework for synchronization between multiple
 47           drivers.  Sync implementations can take advantage of hardware
 48           synchronization built into devices like GPUs.

 50 config SW_SYNC
 51         bool "Software synchronization objects"
 52         default n
 53         depends on SYNC
 54         ---help---
 55           A sync object driver that uses a 32bit counter to coordinate
 56           syncrhronization.  Useful when there is no hardware primitive backing
 57           the synchronization.
 58 
 59 config SW_SYNC_USER
 60         bool "Userspace API for SW_SYNC"
 61         default n
 62         depends on SW_SYNC
 63         ---help---
 64           Provides a user space API to the sw sync object.
 65           *WARNING* improper use of this can result in deadlocking kernel
 66           drivers from userspace.
