+SurfaceReplayer Documentation
+===================
+
+[go/SurfaceReplayer](go/SurfaceReplayer)
+
+SurfaceReplayer is a playback mechanism that allows the replaying of traces recorded by
+[SurfaceInterceptor](go/SurfaceInterceptor) from SurfaceFlinger. It specifically replays
+
+* Creation and deletion of surfaces/displays
+* Alterations to the surfaces/displays called Transactions
+* Buffer Updates to surfaces
+* VSync events
+
+At their specified times to be as close to the original trace.
+
+Usage
+--------
+
+###Creating a trace
+
+SurfaceInterceptor is the mechanism used to create traces. The device needs to be rooted in order to
+utilize it. To allow it to write to the device, run
+
+`setenforce 0`
+
+To start recording a trace, run
+
+`service call SurfaceFlinger 1020 i32 1`
+
+To stop recording, run
+
+`service call SurfaceFlinger 1020 i32 0`
+
+The default location for the trace is `/data/SurfaceTrace.dat`
+
+###Executable
+
+To replay a specific trace, execute
+
+`/data/local/tmp/surfacereplayer /absolute/path/to/trace`
+
+inside the android shell. This will replay the full trace and then exit. Running this command
+outside of the shell by prepending `adb shell` will not allow for manual control and will not turn
+off VSync injections if it interrupted in any way other than fully replaying the trace
+
+The replay will not fill surfaces with their contents during the capture. Rather they are given a
+random color which will be the same every time the trace is replayed. Surfaces modulate their color
+at buffer updates.
+
+**Options:**
+
+- -m pause the replayer at the start of the trace for manual replay
+- -t [Number of Threads] uses specified number of threads to queue up actions (default is 3)
+- -s [Timestamp] switches to manual replay at specified timestamp
+- -n Ignore timestamps and run through trace as fast as possible
+- -l Indefinitely loop the replayer
+- -h displays help menu
+
+**Manual Replay:**
+When replaying, if the user presses CTRL-C, the replay will stop and can be manually controlled
+by the user. Pressing CTRL-C again will exit the replayer.
+
+Manual replaying is similar to debugging in gdb. A prompt is presented and the user is able to
+input commands to choose how to proceed by hitting enter after inputting a command. Pressing enter
+without inputting a command repeats the previous command.
+
+- n - steps the replayer to the next VSync event
+- ni - steps the replayer to the next increment
+- c - continues normal replaying
+- c [milliseconds] - continue until specified number of milliseconds have passed
+- s [timestamp] - continue and stop at specified timestamp
+- l - list out timestamp of current increment
+- h - displays help menu
+
+###Shared Library
+
+To use the shared library include these shared libraries
+
+`libsurfacereplayer`
+`libprotobuf-cpp-full`
+`libutils`
+
+And the static library
+
+`libtrace_proto`
+
+Include the replayer header at the top of your file
+
+`#include <replayer/Replayer.h>`
+
+There are two constructors for the replayer
+
+`Replayer(std::string& filename, bool replayManually, int numThreads, bool wait, nsecs_t stopHere)`
+`Replayer(Trace& trace, ... ditto ...)`
+
+The first constructor takes in the filepath where the trace is located and loads in the trace
+object internally.
+- replayManually - **True**: if the replayer will immediately switch to manual replay at the start
+- numThreads - Number of worker threads the replayer will use.
+- wait - **False**: Replayer ignores waits in between increments
+- stopHere - Time stamp of where the replayer should run to then switch to manual replay
+
+The second constructor includes all of the same parameters but takes in a preloaded trace object.
+To use add
+
+`#include <frameworks/native/cmds/surfacereplayer/proto/src/trace.pb.h>`
+
+To your file
+
+After initializing the Replayer call
+
+ replayer.replay();
+
+And the trace will start replaying. Once the trace is finished replaying, the function will return.
+The layers that are visible at the end of the trace will remain on screen until the program
+terminates.
+
+
+**If VSyncs are broken after running the replayer** that means `enableVSyncInjections(false)` was
+never executed. This can be fixed by executing
+
+`service call SurfaceFlinger 23 i32 0`
+
+in the android shell
+
+Code Breakdown
+-------------
+
+The Replayer is composed of 5 components.
+
+- The data format of the trace (Trace.proto)
+- The Replayer object (Replayer.cpp)
+- The synchronization mechanism to signal threads within the Replayer (Event.cpp)
+- The scheduler for buffer updates per surface (BufferQueueScheduler.cpp)
+- The Main executable (Main.cpp)
+
+### Traces
+
+Traces are represented as a protobuf message located in surfacereplayer/proto/src.
+
+**Traces** contain *repeated* **Increments** (events that have occurred in SurfaceFlinger).
+**Increments** contain the time stamp of when it occurred and a *oneof* which can be a
+
+ - Transaction
+ - SurfaceCreation
+ - SurfaceDeletion
+ - DisplayCreation
+ - DisplayDeleteion
+ - BufferUpdate
+ - VSyncEvent
+ - PowerModeUpdate
+
+**Transactions** contain whether the transaction was synchronous or animated and *repeated*
+**SurfaceChanges** and **DisplayChanges**
+
+- **SurfaceChanges** contain an id of the surface being manipulated and can be changes such as
+position, alpha, hidden, size, etc.
+- **DisplayChanges** contain the id of the display being manipulated and can be changes such as
+size, layer stack, projection, etc.
+
+**Surface/Display Creation** contain the id of the surface/display and the name of the
+surface/display
+
+**Surface/Display Deletion** contain the id of the surface/display to be deleted
+
+**Buffer Updates** contain the id of the surface who's buffer is being updated, the size of the
+buffer, and the frame number.
+
+**VSyncEvents** contain when the VSync event has occurred.
+
+**PowerModeUpdates** contain the id of the display being updated and what mode it is being
+changed to.
+
+To output the contents of a trace in a readable format, execute
+
+`**aprotoc** --decode=Trace \
+-I=$ANDROID_BUILD_TOP/frameworks/native/cmds/surfacereplayer/proto/src \
+$ANDROID_BUILD_TOP/frameworks/native/cmds/surfacereplayer/proto/src/trace.proto \
+ < **YourTraceFile.dat** > **YourOutputName.txt**`
+
+
+###Replayer
+
+Fundamentally the replayer loads a trace and iterates through each increment, waiting the required
+amount of time until the increment should be executed, then executing the increment. The first
+increment in a trace does not start at 0, rather the replayer treats its time stamp as time 0 and
+goes from there.
+
+Increments from the trace are played asynchronously rather than one by one, being dispatched by
+the main thread, queued up in a thread pool and completed when the main thread deems they are
+ready to finish execution.
+
+When an increment is dispatched, it completes as much work as it can before it has to be
+synchronized (e.g. prebaking a buffer for a BufferUpdate). When it gets to a critical action
+(e.g. locking and pushing a buffer), it waits for the main thread to complete it using an Event
+object. The main thread holds a queue of these Event objects and completes the
+corresponding Event base on its time stamp. After completing an increment, the main thread will
+dispatch another increment and continue.
+
+The main thread's execution flow is outlined below
+
+ initReplay() //queue up the initial increments
+ while(!pendingIncrements.empty()) { //while increments remaining
+ event = pendingIncrement.pop();
+ wait(event.time_stamp(); //waitUntil it is time to complete this increment
+
+ event.complete() //signal to let event finish
+ if(increments remaing()) {
+ dispatchEvent() //queue up another increment
+ }
+ }
+
+A worker thread's flow looks like so
+
+ //dispatched!
+ Execute non-time sensitive work here
+ ...
+ event.readyToExecute() //time sensitive point...waiting for Main Thread
+ ...
+ Finish execution
+
+
+### Event
+
+An Event is a simple synchronization mechanism used to facilitate communication between the main
+and worker threads. Every time an increment is dispatched, an Event object is also created.
+
+An Event can be in 4 different states:
+
+- **SettingUp** - The worker is in the process of completing all non-time sensitive work
+- **Waiting** - The worker is waiting on the main thread to signal it.
+- **Signaled** - The worker has just been signaled by the main thread
+- **Running** - The worker is running again and finishing the rest of its work.
+
+When the main thread wants to finish the execution of a worker, the worker can either still be
+**SettingUp**, in which the main thread will wait, or the worker will be **Waiting**, in which the
+main thread will **Signal** it to complete. The worker thread changes itself to the **Running**
+state once **Signaled**. This last step exists in order to communicate back to the main thread that
+the worker thread has actually started completing its execution, rather than being preempted right
+after signalling. Once this happens, the main thread schedules the next worker. This makes sure
+there is a constant amount of workers running at one time.
+
+This activity is encapsulated in the `readyToExecute()` and `complete()` functions called by the
+worker and main thread respectively.
+
+### BufferQueueScheduler
+
+During a **BuferUpdate**, the worker thread will wait until **Signaled** to unlock and post a
+buffer that has been prefilled during the **SettingUp** phase. However if there are two sequential
+**BufferUpdates** that act on the same surface, both threads will try to lock a buffer and fill it,
+which isn't possible and will cause a deadlock. The BufferQueueScheduler solves this problem by
+handling when **BufferUpdates** should be scheduled, making sure that they don't overlap.
+
+When a surface is created, a BufferQueueScheduler is also created along side it. Whenever a
+**BufferUpdate** is read, it schedules the event onto its own internal queue and then schedules one
+every time an Event is completed.
+
+### Main
+
+The main exectuable reads in the command line arguments. Creates the Replayer using those
+arguments. Executes `replay()` on the Replayer. If there are no errors while replaying it will exit
+gracefully, if there are then it will report the error and then exit.
