6 bool "Enable the Anonymous Shared Memory Subsystem"
10 The ashmem subsystem is a new shared memory allocator, similar to
11 POSIX SHM but with different behavior and sporting a simpler
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.
18 tristate "Android log driver"
21 This adds support for system-wide logging using four log buffers.
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.
34 config ANDROID_TIMED_OUTPUT
35 bool "Timed output class driver"
38 config ANDROID_TIMED_GPIO
39 tristate "Android timed gpio driver"
40 depends on GPIOLIB && ANDROID_TIMED_OUTPUT
43 config ANDROID_LOW_MEMORY_KILLER
44 bool "Android Low Memory Killer"
46 Registers processes to be killed when memory is low
48 config ANDROID_INTF_ALARM_DEV
49 tristate "Android alarm driver"
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.
58 bool "Synchronization framework"
61 select DMA_SHARED_BUFFER
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.
68 bool "Software synchronization objects"
72 A sync object driver that uses a 32bit counter to coordinate
73 syncrhronization. Useful when there is no hardware primitive backing
77 bool "Userspace API for SW_SYNC"
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.
