  12         bool "Android Binder IPC Driver"
  13         default n
  14         ---help---
  15           Binder is used in Android for both communication between processes,
  16           and remote method invocation.
  17
  18           This means one Android process can call a method/routine in another
  19           Android process, using Binder to identify, invoke and pass arguments
  20           between said processes.

  22 config ASHMEM
  23         bool "Enable the Anonymous Shared Memory Subsystem"
  24         default n
  25         depends on SHMEM || TINY_SHMEM
  26         ---help---
  27           The ashmem subsystem is a new shared memory allocator, similar to
  28           POSIX SHM but with different behavior and sporting a simpler
  29           file-based API.
  30
  31           It is, in theory, a good memory allocator for low-memory devices,
  32           because it can discard shared memory units when under memory pressure.

  34 config ANDROID_LOGGER
  35         tristate "Android log driver"
  36         default n
  37         ---help---
  38           This adds support for system-wide logging using four log buffers.
  39
  40           These are:
  41
  42               1: main
  43               2: events
  44               3: radio
  45               4: system
  46
  47           Log reading and writing is performed via normal Linux reads and
  48           optimized writes. This optimization avoids logging having too
  49           much overhead in the system.

  61         bool "Android Low Memory Killer"
  62         default N
  63         ---help---
  64           Registers processes to be killed when memory is low
  65
  66 config ANDROID_INTF_ALARM_DEV
  67         bool "Android alarm driver"
  68         depends on RTC_CLASS
  69         default n
  70         ---help---
  71           Provides non-wakeup and rtc backed wakeup alarms based on rtc or
  72           elapsed realtime, and a non-wakeup alarm on the monotonic clock.
  73           Also exports the alarm interface to user-space.
