The Android binder code has been "stable" for many years now. No matter what comes in the future, we are going to have to support this API, so might as well move it to the "real" part of the kernel as there's no real work that needs to be done to the existing code.

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.

tristate "Android alarm driver"

---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.

---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

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

|

default n

|
|
---help---
|
|
Provides a user space API to the sw sync object.
|
|
*WARNING* improper use of this can result in deadlocking kernel
|
|
drivers from userspace.
