 * Data source that controls the system properties used to guard initialization
 * of track_event producers (i.e. Skia) in apps using HWUI, and certain
 * processes like SurfaceFlinger.
 *
 * This data source only tells Skia to initialized the Perfetto SDK and start
 * routing data to the Track Event system instead of ATrace. For those events
 * to actually show up in a trace, the track_event data source must be used as
 * well. The Perfetto SDK cannot be de-initialized, so some long-lived apps and
 * processes may need to be restarted for Skia to revert to using ATrace if
 * Track Events are no longer desired.
 *
 * In addition to switching Skia to use Perfetto's track_event data source,
 * this "guard" also controls Skia's "broad tracing", which removes Skia's
 * internal tracing constraints and allows the track_event config to specify
 * which categories should be traced. Filtering to the "skia.always" category
 * *tag* in a track_event config can be used to re-enable the standard
 * constraints typically used with ATrace.
 *
 * Data source name: android.sdk_sysprop_guard
 * Introduced in Android 14 (U) QPR1.
