+Overview |
+ |
+ This extension lets you mark chromium style GPU traces. Each trace can |
+ specify both a category name and a trace name which will be associated |
+ with the trace. |
+ |
+ Each trace's beginning is marked by TraceBeginCHROMIUM and the end can |
+ optionally be marked by TraceEndCHROMIUM. If the trace's end is not marked, |
+ the trace will automatically end when the graphics context is destroyed. |
+ |
+ Multiple traces can happen simultaneously, however traces act as a stack |
+ and must be fully contained within one another. Therefore, you cannot |
+ have overlapping traces. |
+ |
+ Once a trace has been recorded, it is up to the application to decide |
+ how the traces should be displayed. |
+ |
+New Tokens |
+ |
+ None |
+ |
+New Procedures and Functions |
+ |
+ void TraceBeginCHROMIUM(const char* category_name, const char* trace_name) |
+ |
+ Marks the beginning of when a GPU trace should begin. Once the trace begins |
+ it lasts until the graphics context is destroyed or when TraceEndCHROMIUM |
+ is called. |
+ |
+ |
+ void TraceEndCHROMIUM() |
+ |
+ Marks the last trace to end, this will signal the application to stop |
+ tracing the previous trace. |
+ |
+Errors |
+ |
+ None. |
+ |
+New State |
+ |
+ None. |
