7 Enable support for various drivers needed on the Android platform
12 bool "Enable the Anonymous Shared Memory Subsystem"
16 The ashmem subsystem is a new shared memory allocator, similar to
17 POSIX SHM but with different behavior and sporting a simpler
20 It is, in theory, a good memory allocator for low-memory devices,
21 because it can discard shared memory units when under memory pressure.
24 tristate "Android log driver"
27 This adds support for system-wide logging using four log buffers.
36 Log reading and writing is performed via normal Linux reads and
37 optimized writes. This optimization avoids logging having too
38 much overhead in the system.
40 config ANDROID_TIMED_OUTPUT
41 bool "Timed output class driver"
44 config ANDROID_TIMED_GPIO
45 tristate "Android timed gpio driver"
46 depends on GPIOLIB && ANDROID_TIMED_OUTPUT
49 config ANDROID_LOW_MEMORY_KILLER
50 bool "Android Low Memory Killer"
53 Registers processes to be killed when memory is low
55 config ANDROID_LOW_MEMORY_KILLER_AUTODETECT_OOM_ADJ_VALUES
56 bool "Android Low Memory Killer: detect oom_adj values"
57 depends on ANDROID_LOW_MEMORY_KILLER
60 Detect oom_adj values written to
61 /sys/module/lowmemorykiller/parameters/adj and convert them
62 to oom_score_adj values.
64 config ANDROID_INTF_ALARM_DEV
65 bool "Android alarm driver"
69 Provides non-wakeup and rtc backed wakeup alarms based on rtc or
70 elapsed realtime, and a non-wakeup alarm on the monotonic clock.
71 Also exports the alarm interface to user-space.
74 bool "Synchronization framework"
78 This option enables the framework for synchronization between multiple
79 drivers. Sync implementations can take advantage of hardware
80 synchronization built into devices like GPUs.
83 bool "Software synchronization objects"
87 A sync object driver that uses a 32bit counter to coordinate
88 syncrhronization. Useful when there is no hardware primitive backing
92 bool "Userspace API for SW_SYNC"
96 Provides a user space API to the sw sync object.
97 *WARNING* improper use of this can result in deadlocking kernel
98 drivers from userspace.
