|
|
---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.

|

This option enables the framework for synchronization between multiple
|
|
drivers. Sync implementations can take advantage of hardware
|
|
synchronization built into devices like GPUs.

|

---help---
|
|
A sync object driver that uses a 32bit counter to coordinate
|
|
syncrhronization. Useful when there is no hardware primitive backing
|
|
the synchronization.

Provides a user space API to the sw sync object.
|

*WARNING* improper use of this can result in deadlocking kernel
|

drivers from userspace.
