* Adds a parameter to the wakeup_callback to report sucessful wakeup or ↵Ruchi Kandoi2015-06-252-11/+15
| | | | | | | | | | | suspend aborts. Adds the call to wakeup_callback when the write to the /sys/power/state fails. This will help userspace account for the suspend aborts. Bug: 17478088 Bug: 18179405 Change-Id: Icd1194cfbaf61044ca0b2fe63a10a4c52e1535bc
* Add TEMP_FAILURE_RETRY to libsuspend.Jeff Brown2015-05-183-19/+16
| | | | | | | | | In testing, I observed one instance of a call failing due to a signal sent to the process. This could happen at various times so it's better to be safe than sorry. Bug: 20534809 Change-Id: I42242087300d8b840a50aec34aa6b2e1507cab50

* | autosuspend_inited flag set even if initialization failsKyle Russell2012-11-201-2/+2
|/ | | | | | | | | | | | | | | | | Prevents possible SIGSEGV on second autosuspend_enable attempt when first intialization attempt fails. autosuspend_inited should only be set once autosuspend_ops has been assigned. Consider the first call to autosuspend_enable(). autosuspend_init() sets its inited flag to true, and attempts to set autosuspend_ops. If all the other autosuspend_*_init() attempts fail, autosuspend_init() returns -1, which autosuspend_enable() will return as a failure. A second call to autosuspend_enable() will check autosuspend_init() and see that autosuspend has already been initialized. It will attempt to access autosuspend_ops, which were not set in the first initialization attempt, causing a SIGSEGV. Change-Id: Ib2d3ee62fee4c3b6d0323e5b7f3709a23c6b923f
* libsuspend: force autosleep off during initColin Cross2012-09-211-0/+3
| | | | | | | | | | | | | | | If autosuspend_autosleep_init is called when autosleep is enabled, for example after a runtime restart with the screen off, the kernel autosleep state will be enabled, but autosuspend_enabled is false. Further calls to autosuspend_disable by the framework will not result in autosleep being disabled. Call autosuspend_autosleep_disable from autosuspend_autosleep_init to get the kernel state into a known state that matches the autosuspend_enabled flag.

* | libsuspend: wait for earlysuspend transition to finishColin Cross2012-06-141-2/+40
| | | | | | | | | | | | | | | | | | Wait for the early suspend transition to finish to the point where surfaceflinger would previously have synchronized. This is important during screen on, to ensure the display early suspend handlers have completed before surfaceflinger unblanks. Change-Id: I91ac0253d9655c3f1ae3dd7f1a918c279568b23e
* | libsuspend: always unblock early suspendColin Cross2012-06-071-4/+80
|/ | | | | | | | | SurfaceFlinger and PowerManagerService manage their synchronization without the help of early suspend, and SurfaceFlinger no longer unblocks early suspend. Add a new thread when early suspend is detected that will immediately unblock early suspend. Change-Id: I87ef4984a2ab34cbbb3af8b7762236b9a92dc2ea
