7 Enable support for various drivers needed on the Android platform
11 config ANDROID_BINDER_IPC
12 bool "Android Binder IPC Driver"
15 Binder is used in Android for both communication between processes,
16 and remote method invocation.
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.
23 bool "Enable the Anonymous Shared Memory Subsystem"
27 The ashmem subsystem is a new shared memory allocator, similar to
28 POSIX SHM but with different behavior and sporting a simpler
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.
35 tristate "Android log driver"
38 This adds support for system-wide logging using four log buffers.
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.
51 config ANDROID_TIMED_OUTPUT
52 bool "Timed output class driver"
55 config ANDROID_TIMED_GPIO
56 tristate "Android timed gpio driver"
57 depends on GPIOLIB && ANDROID_TIMED_OUTPUT
60 config ANDROID_LOW_MEMORY_KILLER
61 bool "Android Low Memory Killer"
64 Registers processes to be killed when memory is low
66 config ANDROID_INTF_ALARM_DEV
67 bool "Android alarm driver"
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.
76 bool "Synchronization framework"
80 This option enables the framework for synchronization between multiple
81 drivers. Sync implementations can take advantage of hardware
82 synchronization built into devices like GPUs.
85 bool "Software synchronization objects"
89 A sync object driver that uses a 32bit counter to coordinate
90 syncrhronization. Useful when there is no hardware primitive backing
94 bool "Userspace API for SW_SYNC"
98 Provides a user space API to the sw sync object.
99 *WARNING* improper use of this can result in deadlocking kernel
100 drivers from userspace.
