SW_SYNC allows to run tests on the sync_file framework via debugfs on <debugfs>/sync/sw_sync Opening and closing the file triggers creation and release of a sync timeline. To create fences on this timeline the SW_SYNC_IOC_CREATE_FENCE ioctl should be used. To increment the timeline value use SW_SYNC_IOC_INC. Also it exports Sync information on <debugfs>/sync/info Signed-off-by: Gustavo Padovan <gustavo.padovan@collabora.co.uk> Reviewed-by: Eric Engestrom <eric.engestrom@imgtec.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

|

---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.

---help---

Registers processes to be killed when low memory conditions, this is useful
|
|
as there is no particular swap space on android.
|
|
|
|
The registered process will kill according to the priorities in android init
|
|
scripts (/init.rc), and it defines priority values with minimum free memory size
|
|
for each priority.
