* re-do "Use the Perfetto SDK instead of ATRACE" (#8701) This time we create an entirely new private header: Tracing.h which uses the perfetto SDK instead of ATRACE. The old Systrace.h is unchanged to presever backward compatibility but is essentially deprecated and no longer used within the filament repo. The new TRACING_ macros use an explicit CATEGORY parameter, which is declared in Tracing.h. Moreover, tracing can be compiled out by defining FILAMENT_TRACING_ENABLED to false before including Tracing.h iOS tracing is still supported and still controlled via FILAMENT_APPLE_SYSTRACE. There are three perfetto categories defined: - "filament/filament" - "filament/jobsystem" - "filament/gltfio" The "filament/jobsystem" category is compiled out by default. And they can be enabled in AGI / perfetto by adding: ``` data_sources { config { name: "track_event" track_event_config { disabled_categories: "*" enabled_categories: "filament/filament" enabled_categories: "filament/jobsystem" enabled_categories: "filament/gltfio" } } } ``` * Update libs/utils/include/private/utils/Tracing.h Co-authored-by: Powei Feng <powei@google.com> * Update libs/utils/src/android/Tracing.cpp Co-authored-by: Powei Feng <powei@google.com> * remove all references to SYSTRACE_TAG --------- Co-authored-by: Powei Feng <powei@google.com>
