   4        bool "Android Drivers"
   5        default N
   6        ---help---

  11config ANDROID_BINDER_IPC
  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.

  22config 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.

  34config 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.

  60config ANDROID_LOW_MEMORY_KILLER
  61        bool "Android Low Memory Killer"
  62        default N
  63        ---help---
  64          Registers processes to be killed when memory is low
  65
  66config 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.
