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.
17 config ANDROID_TIMED_OUTPUT
18 bool "Timed output class driver"
21 config ANDROID_TIMED_GPIO
22 tristate "Android timed gpio driver"
23 depends on GPIOLIB && ANDROID_TIMED_OUTPUT
26 config ANDROID_LOW_MEMORY_KILLER
27 bool "Android Low Memory Killer"
29 Registers processes to be killed when memory is low
32 bool "Synchronization framework"
35 select DMA_SHARED_BUFFER
37 This option enables the framework for synchronization between multiple
38 drivers. Sync implementations can take advantage of hardware
39 synchronization built into devices like GPUs.
42 bool "Software synchronization objects"
46 A sync object driver that uses a 32bit counter to coordinate
47 syncrhronization. Useful when there is no hardware primitive backing
51 bool "Userspace API for SW_SYNC"
55 Provides a user space API to the sw sync object.
56 *WARNING* improper use of this can result in deadlocking kernel
57 drivers from userspace.
