2022-02-15Merge "Use VsyncEventData in DisplayEventReceiver::Event." Rachel Lee
2022-02-14Use VsyncEventData in DisplayEventReceiver::Event. Rachel Lee
Clean-up that re-uses VsyncEventData so it's easier to maintain. The ParcelableVsyncEventData is used in AIDL. It is separated from VsyncEventData because of the union in DisplayEventReceiver::Event and Parcelable has non-trivial constructors.

2020-11-18SurfaceFlinger: Add DISPLAY_EVENT_FRAME_RATE_OVERRIDE Ady Abraham
Add a new event to DisplayEventReceiver that conveys a list of apps whose frame rates have been overriden. This event is processed by the DisplayManager to advertise the new frame rate to the overridden app. Change-Id: I89fce8b5b4d9db65ec5db7dd2393c384c0fcfd82 Bug: 169271059 Bug: 169271062 Bug: 170503758 Test: manual test using SF backdoor
2020-08-07Fix refresh rate callback fan-out for choreographer Alec Mouri
* AChoreographer receives refresh rates from DisplayManager already, so there's no need to default-enable them - AChoreographer only needs to pump an event with the latest refresh rate to wake up looper. This also ensures that AChoreographer's callbacks are entirely in-sync with DisplayManager since there's no raciness. * Instead of re-requesting a config change from SF, instead inject it in AChoreographer correctly to save on binder. Bug: 154874011 Bug: 158680912 Bug: 161406626 Test: while [ true ]; do adb shell service call SurfaceFlinger 1035 i32 1; adb shell service call SurfaceFlinger 1035 i32 0; and repeatedly rotate the home screen with auto-rotate off.

2020-05-07Receive refresh rate callbacks from DMS Alec Mouri
AChoreographer will use DMS as the source of truth for these callbacks instead of SurfaceFlinger. Bug: 154874011 Test: ChoreographerNativeTest Tes: Manually verify that HWUI is processing refresh rate callbacks Change-Id: I961a7d1ab335800d3e260ba7564ddca9c0595cfc
2019-12-26[AChoreographer] Add refresh rate callback. Alec Mouri
This will augment the NDK to respond to display events where the display refresh rate changes. Consumers of this api will include: * HWUI, for implementing a policy for determining whether to use render-ahead, * Swappy, to potentially replace jumping into Java from native code to respond to display evnets there. * Any other native app that would rely on the up-to-date display refresh rate. Currently however this is not yet exposed to NDK as CTS is not yet written. Once CTS is written then this will be formally exposed to NDK. For now we'll leave these as APEX apis to represent incremental progress. Bug: 136262896 Test: builds Change-Id: I66d393f93eb5d681547411e330ef1b8950a35c5d
2019-06-05SurfaceFlinger: add explicit register for DISPLAY_EVENT_CONFIG_CHANGED Ady Abraham
When display refresh rate changes, SF fires DISPLAY_EVENT_CONFIG_CHANGED thru DisplayEventReceiver. If the other end of the pipe doesn't consume the events it may lead to pipe full and dropping of events. Furthermore, The only clients interested in this event in DisplayManager and hwui. To avoid spamming all clients with this event, this change is adding an explicit register for DISPLAY_EVENT_CONFIG_CHANGED events. Bug: 131688378 Test: adb shell /data/nativetest64/libsurfaceflinger_unittest/libsurfaceflinger_unittest Test: trigger config change and observe logcat Change-Id: I5973a1ecc1f3e3ff8d8a0cba19db0e49ef0d5341

2017-04-06libgui: Remove RefBase from BitTube Dan Stoza
Removes RefBase from BitTube, since because it is not a Binder object, it doesn't need to be reference-counted in this way. In the process, we rename IDisplayEventConnection::getDataChannel to IDEC::stealReceiveChannel to make it clearer that this is a non-const operation on the remote end that removes its access to the receive channel. This also adds a couple of methods for moving the receive file descriptor out of one BitTube and into another, since this is the essence of the IDisplayEventConnection::stealReceiveChannel method, and now with C++11 move semantics, we can do this without needing to return an sp<> from EventThread's implementation of stealReceiveChannel. Test: m -j + manual testing Change-Id: Ibaaca2a14fb6155052fe5434c14bc3e671b43743
2017-04-06libgui: Format BitTube and move into gui namespace Dan Stoza
Reformats BitTube using the framework default .clang-format and moves it into the android::gui namespace. Test: m -j + manual testing Change-Id: I5ea748b809f37c2ec4dcfb41e7b84daf7a084368
2017-04-06libgui: Normalize IDisplayEventConnection methods Dan Stoza
This change modifies the IDisplayEventConnection API such that every synchronous method returns a status_t (to be able to return transport errors). This required changing getDataChannel to return its channel by output parameter rather than return type. Currently no more error messages are checked than before, but this will both enable calling code to check error messages if it desires and, more importantly, allow the Bp/Bn code to be semi-automatically generated using SafeInterface. Test: libgui_tests + manual testing Change-Id: I8d5bc5ef0475cee07b638a97079b234f0384c022

2012-02-01separate transactions from updates Mathias Agopian
with this changes, SF transactions are handled as soon as possible but do not trigger updates. the update is delayed until the next vsync. this allows us to work much better without requiring triple-buffering. Change-Id: I1fa10794d0cf742129f0877698b7b1e1f2ec7401

2011-12-06Improve the VSYNC api a bit. Mathias Agopian
- add the ability to set the vsync delivery rate, when the rate is set to N>1 (ie: receive every N vsync), SF process' is woken up for all of vsync, but clients only see the every N events. - add the concept of one-shot vsync events, with a call-back to request the next one. currently the call-back is a binder IPC. Change-Id: I09f71df0b0ba0d88ed997645e2e2497d553c9a1b
2011-11-29Add support for sending VSYNC events to the framework Mathias Agopian
use gui/DisplayEvent to receive the events. Events are dispatched through a unix pipe, so the API is compatible with utils/Looper. see gui/DisplayEvent.h for more info. Bug: 1475048 Change-Id: Ia720f64d1b950328b47b22c6a86042e481d35f09
