5config ASHMEM
6 bool "Enable the Anonymous Shared Memory Subsystem"
7 default n
8 depends on SHMEM
9 ---help---
10 The ashmem subsystem is a new shared memory allocator, similar to
11 POSIX SHM but with different behavior and sporting a simpler
12 file-based API.
13
14 It is, in theory, a good memory allocator for low-memory devices,
15 because it can discard shared memory units when under memory pressure.

17config ANDROID_LOGGER
18 tristate "Android log driver"
19 default n
20 ---help---
21 This adds support for system-wide logging using four log buffers.
22
23 These are:
24
25 1: main
26 2: events
27 3: radio
28 4: system
29
30 Log reading and writing is performed via normal Linux reads and
31 optimized writes. This optimization avoids logging having too
32 much overhead in the system.

48config ANDROID_INTF_ALARM_DEV
49 tristate "Android alarm driver"
50 depends on RTC_CLASS
51 default n
52 ---help---
53 Provides non-wakeup and rtc backed wakeup alarms based on rtc or
54 elapsed realtime, and a non-wakeup alarm on the monotonic clock.
55 Also exports the alarm interface to user-space.
56
57config SYNC
58 bool "Synchronization framework"
59 default n
60 select ANON_INODES
61 select DMA_SHARED_BUFFER
62 ---help---
63 This option enables the framework for synchronization between multiple
64 drivers. Sync implementations can take advantage of hardware
65 synchronization built into devices like GPUs.
66
67config SW_SYNC
68 bool "Software synchronization objects"
69 default n
70 depends on SYNC
71 ---help---
72 A sync object driver that uses a 32bit counter to coordinate
73 syncrhronization. Useful when there is no hardware primitive backing
74 the synchronization.
75
76config SW_SYNC_USER
77 bool "Userspace API for SW_SYNC"
78 default n
79 depends on SW_SYNC
80 ---help---
81 Provides a user space API to the sw sync object.
82 *WARNING* improper use of this can result in deadlocking kernel
83 drivers from userspace.
