7 Enable support for various drivers needed on the Android platform
11 config ANDROID_BINDER_IPC
12 bool "Android Binder IPC Driver"
16 Binder is used in Android for both communication between processes,
17 and remote method invocation.
19 This means one Android process can call a method/routine in another
20 Android process, using Binder to identify, invoke and pass arguments
21 between said processes.
24 bool "Enable the Anonymous Shared Memory Subsystem"
28 The ashmem subsystem is a new shared memory allocator, similar to
29 POSIX SHM but with different behavior and sporting a simpler
32 It is, in theory, a good memory allocator for low-memory devices,
33 because it can discard shared memory units when under memory pressure.
36 tristate "Android log driver"
39 This adds support for system-wide logging using four log buffers.
48 Log reading and writing is performed via normal Linux reads and
49 optimized writes. This optimization avoids logging having too
50 much overhead in the system.
52 config ANDROID_TIMED_OUTPUT
53 bool "Timed output class driver"
56 config ANDROID_TIMED_GPIO
57 tristate "Android timed gpio driver"
58 depends on GPIOLIB && ANDROID_TIMED_OUTPUT
61 config ANDROID_LOW_MEMORY_KILLER
62 bool "Android Low Memory Killer"
65 Registers processes to be killed when memory is low
67 config ANDROID_INTF_ALARM_DEV
68 bool "Android alarm driver"
72 Provides non-wakeup and rtc backed wakeup alarms based on rtc or
73 elapsed realtime, and a non-wakeup alarm on the monotonic clock.
74 Also exports the alarm interface to user-space.
77 bool "Synchronization framework"
81 This option enables the framework for synchronization between multiple
82 drivers. Sync implementations can take advantage of hardware
83 synchronization built into devices like GPUs.
86 bool "Software synchronization objects"
90 A sync object driver that uses a 32bit counter to coordinate
91 syncrhronization. Useful when there is no hardware primitive backing
95 bool "Userspace API for SW_SYNC"
99 Provides a user space API to the sw sync object.
100 *WARNING* improper use of this can result in deadlocking kernel
101 drivers from userspace.
