config ANDROID
|

bool "Android Drivers"

Enable support for various drivers needed on the Android platform

bool "Android Binder IPC Driver"
|

depends on MMU
|
|
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 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.

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.

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.
