 ### Timestamp bases
 
 By default, event timestamps are recorded relative to the time of the first event received during
-the recording. Passing `--timestamp-base=boot` causes the timestamps to be recorded relative to the
-system boot time instead. While this does not affect the playback of the recording, it can be useful
-for matching recorded events with other logs that use such timestamps, such as `dmesg` or the
-touchpad gesture debug logs emitted by `TouchpadInputMapper`.

+timestamps, relative to the Unix epoch (00:00:00 UTC on 1st January 1970). While this does not

  * APerformanceHint allows apps to create performance hint sessions for groups

  * counterpart to the Java PerformanceHintManager SDK API.
  *
+ * This API is intended for periodic workloads, such as frame production. Clients are
+ * expected to create an instance of APerformanceHintManager, create a session with
+ * that, and then set a target duration for the session. Then, they can report the actual
+ * work duration at the end of each cycle to inform the framework about how long those
+ * workloads are taking. The framework will then compare the actual durations to the target
+ * duration and attempt to help the client reach a steady state under the target.
+ *
+ * Unlike reportActualWorkDuration, the "notify..." hints are intended to be sent in
+ * advance of large changes in the workload, to prevent them from going over the target
+ * when there is a sudden, unforseen change. Their effects are intended to last for only
+ * one cycle, after which reportActualWorkDuration will have a chance to catch up.
+ * These hints should be used judiciously, only in cases where the workload is changing
+ * substantially. To enforce that, they are tracked using a per-app rate limiter to avoid
+ * excessive hinting and encourage clients to be mindful about when to send them.

+### Buffer Stuffing and Recovery ###
+
+Buffer stuffing happens on the client side when SurfaceFlinger misses a frame, but the client continues producing buffers at the same rate. This could occur anytime when SurfaceFlinger does not meet the expected timeline’s deadline to finish composing a frame. As a result, SurfaceFlinger cannot yet release the buffer for the frame that it missed and the client has one less buffer to render into. The client may then run out of buffers or have to wait for buffer release callbacks, increasing the chances of janking when clients render multiple windows.
+
+Recovery is implemented by first detecting when buffer stuffing occurs and ensuring that the elevated buffer counts in the server are from a relevant SurfaceControl (is a ViewRootImpl). Other SurfaceControl buffer producers such as games, media, and camera have other reasons for expectedly increased buffer counts, which do not need buffer stuffing recovery.
+
+The actual recovery adjusts the animation timeline in the Choreographer so that the client deadlines for subsequent frames are moved forward in time by one frame. This approach adjusts the client buffer production timeline such that SurfaceFlinger does not fall behind when it misses a frame because the client will simply match its frame production rate with SurfaceFlinger. Ordinarily, buffer stuffing is problematic because the client continues producing buffers when SurfaceFlinger is behind. However, if the client delays producing its buffers to match SurfaceFlinger’s rate, the animation has new frame deadlines that can be reasonably met. The animation is effectively paused for one frame longer than originally intended, and continues the remainder of the animation normally.

+ * On devices that are capable of running the display at different frame rates,
+ * the system may choose a display refresh rate to better match this surface's frame
+ * rate. Usage of this API won't introduce frame rate throttling, or affect other
+ * aspects of the application's frame production pipeline. However, because the system
+ * may change the display refresh rate, calls to this function may result in changes
+ * to Choreographer callback timings, and changes to the time interval at which the
+ * system releases buffers back to the application.
+ *
+ * Note that this only has an effect for surfaces presented on the display. If this
+ * surface is consumed by something other than the system compositor, e.g. a media
+ * codec, this call has no effect.
+ *
+ * You can register for changes in the refresh rate using
+ * \a AChoreographer_registerRefreshRateCallback.
+ *
+ * See ANativeWindow_clearFrameRate().
+ *
+ * Available since API level 36.
+ *
+ * \param window pointer to an ANativeWindow object.
+ *
+ * \param desiredMinRate The desired minimum frame rate (inclusive) for the window, specifying that
+ * the surface prefers the device render rate to be at least `desiredMinRate`.
+ *
+ * <p>Set `desiredMinRate` = `desiredMaxRate` to indicate the surface prefers an exact frame rate.
+ *
+ * <p>Set `desiredMinRate` = 0 to indicate the window has no preference
+ * and any frame rate is acceptable.
+ *
+ * <p>The value should be greater than or equal to 0.
+ *
+ * \param desiredMaxRate The desired maximum frame rate (inclusive) for the window, specifying that
+ * the surface prefers the device render rate to be at most `desiredMaxRate`.
+ *
+ * <p>Set `desiredMaxRate` = `desiredMinRate` to indicate the surface prefers an exact frame rate.
+ *
+ * <p>Set `desiredMaxRate` = positive infinity to indicate the window has no preference
+ * and any frame rate is acceptable.
+ *
+ * <p>The value should be greater than or equal to `desiredMinRate`.
+ *
+ * \param fixedSourceRate The "fixed source" frame rate of the window if the content has an
+ * inherently fixed frame rate, e.g. a video that has a specific frame rate.
+ *
+ * <p>When the frame rate chosen for the surface is the `fixedSourceRate` or a
+ * multiple, the surface can render without frame pulldown, for optimal smoothness. For
+ * example, a 30 fps video (`fixedSourceRate`=30) renders just as smoothly on 30 fps,
+ * 60 fps, 90 fps, 120 fps, and so on.
+ *
+ * <p>Setting the fixed source rate can also be used together with a desired
+ * frame rate min and max via setting `desiredMinRate` and `desiredMaxRate`. This still
+ * means the window's content has a fixed frame rate of `fixedSourceRate`, but additionally
+ * specifies the preference to be in the range [`desiredMinRate`, `desiredMaxRate`]. For example, an
+ * app might want to specify there is 30 fps video (`fixedSourceRate`=30) as well as a smooth
+ * animation on the same window which looks good when drawing within a frame rate range such as
+ * [`desiredMinRate`, `desiredMaxRate`] = [60,120].
+ *
+ * \param changeFrameRateStrategy Whether display refresh rate transitions caused by this surface
+ * should be seamless. A seamless transition is one that doesn't have any visual interruptions, such
+ * as a black screen for a second or two.

 This allows control to be delegated to different parts of the system - such as SystemServer,
 SysUI and Apps.
 
+### Layer Drawing Order
+Layers are drawn based on an inorder traversal, treating relative parents as
+direct parents. Negative z-values place layers below their parent, while
+non-negative values place them above. Layers with the same z-value are drawn
+in creation order (newer on top).  However, relying on creation order for
+z-ordering is discouraged; use unique z-values whenever possible for better
+control.
+
+Traversal pseudo code:
+```
+fn traverseBottomToTop(root):
+  for each child node including relative children,
+    sorted by z then layer id, with z less than 0:
+          traverseBottomToTop(childNode)
+
+  visit(root)
+
+  for each child node including relative children,
+    sorted by z then layer id, with z greater than
+    or equal to 0:
+          traverseBottomToTop(childNode)
+```

 ### Layer Lifecycle
 Layer is created by a client. The client receives a strong binder reference to the layer
 handle, which will keep the layer alive as long as the client holds the reference. The
