3config ANDROID
4	bool "Android Drivers"
5	default N
6	---help---
7	  Enable support for various drivers needed on the Android platform

11config ANDROID_BINDER_IPC
12	bool "Android Binder IPC Driver"
13	depends on MMU
14	default n
15	---help---
16	  Binder is used in Android for both communication between processes,
17	  and remote method invocation.
18
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.

23config ASHMEM
24	bool "Enable the Anonymous Shared Memory Subsystem"
25	default n
26	depends on SHMEM
27	---help---
28	  The ashmem subsystem is a new shared memory allocator, similar to
29	  POSIX SHM but with different behavior and sporting a simpler
30	  file-based API.
31
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.
34
35config ANDROID_LOGGER
36	tristate "Android log driver"
37	default n
38	---help---
39	  This adds support for system-wide logging using four log buffers.
40
41	  These are:
42
43	      1: main
44	      2: events
45	      3: radio
46	      4: system
47
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.

52config ANDROID_TIMED_OUTPUT
53	bool "Timed output class driver"
54	default y

56config ANDROID_TIMED_GPIO

61config ANDROID_LOW_MEMORY_KILLER
62	bool "Android Low Memory Killer"
63	default N
64	---help---
65	  Registers processes to be killed when memory is low
66
67config ANDROID_INTF_ALARM_DEV
68	bool "Android alarm driver"
69	depends on RTC_CLASS
70	default n
71	---help---
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.
75
76config SYNC
77	bool "Synchronization framework"
78	default n
79	select ANON_INODES
80	help
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.
84
85config SW_SYNC
86	bool "Software synchronization objects"
87	default n
88	depends on SYNC
89	help
90	  A sync object driver that uses a 32bit counter to coordinate
91	  syncrhronization.  Useful when there is no hardware primitive backing
92	  the synchronization.
93
94config SW_SYNC_USER
95	bool "Userspace API for SW_SYNC"
96	default n
97	depends on SW_SYNC
98	help
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.
