|\ | | | | | | | | | | | | overloads BBinder::dump" * commit '46ca041f43e3d80029782b12c994b232dc01b5d5': Don't error out because SensorEventConnection::dump overloads BBinder::dump
| * Don't error out because SensorEventConnection::dump overloads BBinder::dumpBernhard Rosenkränzer2014-11-251-0/+7
| | | | | | | | | | | | | | | | | | | | | | clang warns about SensorEventConnection::dump overloading BBinder::dump in some conditions. Since the cause isn't fixable without changing the API, tell clang not to error out on it.

* | Add a timeout for releasing SensorService wake_lock.Aravind Akella2014-11-011-1/+20
|/ | | | | | | | | If SensorService is holding a wake_lock and there are no acknowledgements from ANY app within 5 seconds, release the wake_lock and reset the wake_lock refcounts for all connections. Bug: 16874240 Change-Id: I5e950dd393c20173c439cbd5a4ba614ee09d61f4
* Fix sockfd leakage in SensorService.Aravind Akella2014-10-021-3/+26
| | | | | | | | | | | | i) Call removeFd() only if the fd in the BitTube has been previously added to the Looper. Use a flag to determine whether the fd has been previously added or not. ii) Increment mPendingFlushEventsToSend after holding a connectionLock. iii) Store the number of acks that are pending in SensorEventQueue and send them all at once. Bug: 17472228 Change-Id: I1ec834fea1112a9cfbd9cddd2198438793698502
* SensorService fixes.Aravind Akella2014-09-151-3/+3
| | | | | | | | | | i) Initialize sensor_event.flags to zero or wake_up flag before sending dropped flush_complete_events. This will avoid unnecessary acks. Currently it is not set to anything which may result in garbage values for flags field. ii) Change the dump format of SensorEventConnection. iii) Add const to method signatures wherever applicable.

* SensorService fixesAravind Akella2014-09-101-9/+6
| | | | | | | | | | | | | | | i) Significant Motion multiple clients fix. Make a copy of mActiveConnections vector before cleaning up SensorEventConnections when one-shot sensors trigger. ii) Maintain a mapping between flush_complete_events and SensorEventConnections to accurately map flush() API calls and corresponding flush_complete_events iii) Remove all references to 1_1 and 1_2 HALs. iv) Dynamically allocate sensor_event buffers in SensorService main threadLoop. Bug: 17412359 Change-Id: If3c3986197660cafef2d2e0b4dc7582e229cf1c4
* SensorService flush fixes.Aravind Akella2014-09-031-3/+10
| | | | | | | | | | i) Fix a possible race condition when adding a pending flush connection to mActiveSensors data structure. ii) Invalidate flush_complete_events as soon as they are consumed by a connection so that they are not used by other connections which are registered for the same sensor. Change-Id: I1491bea8c2081c4aab1feacc60add13b7aa26bb7
* SensorService fixesAravind Akella2014-08-221-0/+2
| | | | | | | | 1) Limit maxEventsToWrite depending on the size of the socket buffer allocated (Fix for write failure on manta). 2) Do not call flush() if the sensor is not activated (OEM issue). Change-Id: I81ea78dbdef3a3773af505ca1c9a5e39492c0b48
* SensorService fixes.Aravind Akella2014-08-211-0/+1
| | | | | | | i) Add more debug stats (acks needed, acks received) ii) Comment out write failure message. Change-Id: Iac892a66530849a2dd023d6f5628cd070a79537d
* SensorService fixes.Aravind Akella2014-08-191-11/+25
| | | | | | | | | | | | | | | 1) Flush should only be received by the app calling flush(). Maintain a queue of all flush() calls and send flush_complete events in that order. 2) Log warnings for older HALs. Remove batch() calls with DRY_RUN flag. 3) Reallocate event cache when more sensors register and the desired maxCacheSize increases. Clear NEEDS_ACK flag in the buffer whenever there is a write() failure. 4) More dump information. Add wake-up flag, maxDelay and timestamps for sensor events. Bug: 16874778 Change-Id: I195646191059fd31f75f2f07886c0f98bf9b509a
* SensorService performance improvements.Aravind Akella2014-07-241-7/+44
| | | | | | | | | i) Send ack for wake_up sensors on the socket connection instead of using Binder RPC. ii) Cache events per connection in case there are write failures. Compute cache size from FIFO counts of sensors. iii) Send FlushCompleteEvent only for apps that explicitly called flush(). Change-Id: I018969736b7794b1b930529586f2294a03ee8667
* Enable wakeup sensors.Aravind Akella2014-04-231-7/+24
| | | | | | | | SensorService should hold a wakelock till the app reads events from a wakeup sensor. Currently drivers hold a wakelock with a timeout while delivering events from a wake up sensor like Significant Motion. This hack can be removed now.

| | | | | | | | | | | | | | | | | | | | | | | | sensorservice would deadlock if for some reason a sensor failed to enable. simplifed the code a bit, and made it behave a little closer to mr1.1 -- I couldn't convince myself that some changes in how locks were used were correct.

* | various fixes to the sensorserviceMathias Agopian2013-05-161-2/+2
| | | | | | | | | | | | | | | | 1) "google" sensors are now reporting AOSP as the vendor string 2) don't expose the system's sensor fusion if the HAL provides it 3) use uncalibrated gyro if availble for the system's sensor fusion Change-Id: I25140436cdb29d55e39fd6fbbf8c44a410a83d5c

* PermissionCache caches permission checksMathias Agopian2012-06-271-2/+0
| | | | | | | | | | | | | This is intended to absorb the cost of the IPC to the permission controller. Cached permission checks cost about 3us, while full blown ones are two orders of magnitude slower. CAVEAT: PermissionCache can only handle system permissions safely for now, because the cache is not purged upon global permission changes. Change-Id: I8b8a5e71e191e3c01e8f792f253c379190eee62e
* improve orientation sensor with gyro dataMathias Agopian2012-06-271-0/+1
| | | | | | | | | when we do our own sensor fusion, we also export an improved orientation sensor and hide the HAL sensor. The fused orientation sensor is much more precise, fast and smooth. Change-Id: I0ea843b47ad9d12f6b22cce51f8629852d423126

* Add support for virtual sensors.Mathias Agopian2012-06-271-15/+12
| | | | | | | | | | | | | | | | | | | | | | Rework sensorservice to allow "virtual sensors", that is sensors that report a synthetized value based on real sensors. the main change to sensorservice is around managing which real sensor need to be activated and which rate to use. The logic for all this has been moved into SensorDevice, which essentially wraps the sensor HAL but adds two features to it: - it keeps track of which sensors need to be activated - it keeps track of what rate needs to be used For this purpose an "identity" is associated with each real sensor activation, so we can track them. On start-up we check for gravity, linear-acceleration and rotation-vector sensors, if they're not present in the HAL, we synthetize them in sensor-service. Change-Id: I841db2c1b37ef127ed571efa21732ecc5adf1800
* Fix a race condition in sensormanagerMathias Agopian2012-06-271-1/+2
| | | | | | | | | | | | the per-connection state assumed the main sensorservice lock was held during access. This is however not true while pre-processing the events just before sending them to clients. Therefore, there was a small window during which this state could be modified while being used. we now have an internal lock that protects this state. Change-Id: I594680f20f09d6a4f1f38f093a1d3f650dcef1be
* record the last event received regardless of having clients or notMathias Agopian2012-06-271-0/+2
| | | | | | | | | | | | We only recorded the last received event (which is needed when a sensor is activated on a connection) when there was some connection active. This should fix an issue where sometimes the light sensor doesn't return an event whent activated. we also didn't need to hold the main lock while dispatching events to clients. Change-Id: I6c6386c040051ce205e3c0516c678e0603fa45e1
* improve sensorservice dumpsys and increase the max sensor rate to 1 ms (1000Hz)Mathias Agopian2012-06-271-2/+2
| | | | | | | the increased maximum rate is needed for proper gyro integration, current gyro parts can sample at up to 800Hz Change-Id: Ide75f6d5bc7a0fdafeb2dafd72db39e7afb9e794
* SensorService handles last known state properlyMathias Agopian2012-06-271-1/+4
| | | | | | | | | | SensorService now correctly sends the last known state of a sensor as soon as a new connection is made. This fixes the issue where, for instance, an application could wait a long time before getting the light or proximity sensor initial state. Change-Id: Ic41392f3626e26c4f15746c7e17c7ecd44bbb10b
* filter sensor event by connectionMathias Agopian2012-06-271-3/+2
