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	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.
74
75config SYNC
76	bool "Synchronization framework"
77	default n
78	select ANON_INODES
79	help
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.
83
84config SW_SYNC
85	bool "Software synchronization objects"
86	default n
87	depends on SYNC
88	help
89	  A sync object driver that uses a 32bit counter to coordinate
90	  syncrhronization.  Useful when there is no hardware primitive backing
91	  the synchronization.
92
93config SW_SYNC_USER
94	bool "Userspace API for SW_SYNC"
95	default n
96	depends on SW_SYNC
97	help
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.
