menu "Android"
config ANDROID
bool "Android Drivers"
default N
---help---
Enable support for various drivers needed on the Android platform
if ANDROID
config ANDROID_BINDER_IPC
bool "Android Binder IPC Driver"
default n
---help---
Binder is used in Android for both communication between processes,
and remote method invocation.
This means one Android process can call a method/routine in another
Android process, using Binder to identify, invoke and pass arguments
between said processes.
config ANDROID_BINDER_IPC_32BIT
bool "Use old 32-bit binder api"
default y
depends on !64BIT
---help---
Enable to support an old 32-bit Android user-space. Breaks the new
Android user-space.
config ASHMEM
bool "Enable the Anonymous Shared Memory Subsystem"
default n
depends on SHMEM
---help---
The ashmem subsystem is a new shared memory allocator, similar to
POSIX SHM but with different behavior and sporting a simpler
file-based API.
It is, in theory, a good memory allocator for low-memory devices,
because it can discard shared memory units when under memory pressure.
config ANDROID_LOGGER
tristate "Android log driver"
default n
---help---
This adds support for system-wide logging using four log buffers.
These are:
1: main
2: events
3: radio
4: system
Log reading and writing is performed via normal Linux reads and
optimized writes. This optimization avoids logging having too
much overhead in the system.
config ANDROID_TIMED_OUTPUT
bool "Timed output class driver"
default y
config ANDROID_TIMED_GPIO
tristate "Android timed gpio driver"
depends on GPIOLIB && ANDROID_TIMED_OUTPUT
default n
config ANDROID_LOW_MEMORY_KILLER
bool "Android Low Memory Killer"
default N
---help---
Registers processes to be killed when memory is low
config ANDROID_LOW_MEMORY_KILLER_AUTODETECT_OOM_ADJ_VALUES
bool "Android Low Memory Killer: detect oom_adj values"
depends on ANDROID_LOW_MEMORY_KILLER
default y
---help---
Detect oom_adj values written to
/sys/module/lowmemorykiller/parameters/adj and convert them
to oom_score_adj values.
config ANDROID_LOW_MEMORY_KILLER_AUTODETECT_OOM_ADJ_VALUES
bool "Android Low Memory Killer: detect oom_adj values"
depends on ANDROID_LOW_MEMORY_KILLER
default y
---help---
Detect oom_adj values written to
/sys/module/lowmemorykiller/parameters/adj and convert them
to oom_score_adj values.
config ANDROID_INTF_ALARM_DEV
bool "Android alarm driver"
depends on RTC_CLASS
default n
---help---
Provides non-wakeup and rtc backed wakeup alarms based on rtc or
elapsed realtime, and a non-wakeup alarm on the monotonic clock.
Also exports the alarm interface to user-space.
config SYNC
bool "Synchronization framework"
default n
select ANON_INODES
help
This option enables the framework for synchronization between multiple
drivers. Sync implementations can take advantage of hardware
synchronization built into devices like GPUs.
config SW_SYNC
bool "Software synchronization objects"
default n
depends on SYNC
help
A sync object driver that uses a 32bit counter to coordinate
syncrhronization. Useful when there is no hardware primitive backing
the synchronization.
config SW_SYNC_USER
bool "Userspace API for SW_SYNC"
default n
depends on SW_SYNC
help
Provides a user space API to the sw sync object.
*WARNING* improper use of this can result in deadlocking kernel
drivers from userspace.
