[PATCH v1 0/3] Binder: Enable App Freezing Capability

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Li Li <dualli@xxxxxxxxxx>

To improve the user experience when switching between recently used
applications, the background applications which are not currently needed
are cached in the memory. Normally, a well designed application will not
consume valuable CPU resources in the background. However, it's possible
some applications are not able or willing to behave as expected, wasting
energy even after being cached.

It is a good idea to freeze those applications when they're only being
kept alive for the sake of faster startup and energy saving. These kernel
patches will provide the necessary infrastructure for user space framework
to freeze and thaw a cached process, check the current freezing status and
correctly deal with outstanding binder transactions to frozen processes.

Marco Ballesio (3):
  binder: BINDER_FREEZE ioctl
  binder: use EINTR for interrupted wait for work
  binder: BINDER_GET_FROZEN_INFO ioctl
