Currently the Gecko Profiler defines a moderate amount of stuff when MOZ_GECKO_PROFILER is undefined. It also #includes various headers, including JS ones. This is making it difficult to separate Gecko's media stack for inclusion in Servo. This patch greatly simplifies how things are exposed. The starting point is: - GeckoProfiler.h can be #included unconditionally; - everything else from the profiler must be guarded by MOZ_GECKO_PROFILER. In practice this introduces way too many #ifdefs, so the patch loosens it by adding no-op macros for a number of the most common operations. The net result is that #ifdefs and macros are used a bit more, but almost nothing is exposed in non-MOZ_GECKO_PROFILER builds (including ProfilerMarkerPayload.h and GeckoProfiler.h), and understanding what is exposed is much simpler than before. Note also that in BHR, ThreadStackHelper is now entirely absent in non-MOZ_GECKO_PROFILER builds.

|
* to give content a chance to recover.
|

*
|
|
* If the lower level VR platform API's are rejecting submitted frames,

* such as when the Oculus "Health and Safety Warning" is displayed,

* we will not kick off the next frame immediately after VRDisplay.submitFrame

* as it would result in an unthrottled render loop that would free run at

|
* potentially extreme frame rates. To ensure that content has a chance to
|
|
* resume its presentation when the frames are accepted once again, we rely
|
|
* on this "watchdog" to act as a VR refresh driver cycling at a rate defined
|

* by kVRDisplayRAFMaxDuration.

* kVRDisplayRAFMaxDuration is the number of milliseconds since last frame

|
|
* kVRDisplayRAFMaxDuration determines the rate at which RAF callbacks
|
|
* will be called.
|

*
|
|
* This number must be larger than the slowest expected frame time during
|
|
* normal VR presentation, but small enough not to break content that
|
|
* makes assumptions of reasonably minimal VSync rate.
|
|
*
|
|
* The slowest expected refresh rate for a VR display currently is an
|
|
* Oculus CV1 when ASW (Asynchronous Space Warp) is enabled, at 45hz.
|
|
* A kVRDisplayRAFMaxDuration value of 50 milliseconds results in a 20hz
|
|
* rate, which avoids inadvertent triggering of the watchdog during
|
|
* Oculus ASW even if every second frame is dropped.
