6 bool "Enable the Anonymous Shared Memory Subsystem"
7 default n
8 depends on SHMEM
9 ---help---
10 The ashmem subsystem is a new shared memory allocator, similar to
11 POSIX SHM but with different behavior and sporting a simpler
12 file-based API.
13
14 It is, in theory, a good memory allocator for low-memory devices,
15 because it can discard shared memory units when under memory pressure.

36 ---help---
37 This option enables the framework for synchronization between multiple
38 drivers. Sync implementations can take advantage of hardware
39 synchronization built into devices like GPUs.

41config SW_SYNC
42 bool "Software synchronization objects"
43 default n
44 depends on SYNC
45 ---help---
46 A sync object driver that uses a 32bit counter to coordinate
47 syncrhronization. Useful when there is no hardware primitive backing
48 the synchronization.

50config SW_SYNC_USER
51 bool "Userspace API for SW_SYNC"
52 default n
53 depends on SW_SYNC
54 ---help---
55 Provides a user space API to the sw sync object.
56 *WARNING* improper use of this can result in deadlocking kernel
57 drivers from userspace.
