https://github.com/apitrace/apitrace/commit/35857d9add2d4b50944474e6e89f121c1923b07eadds
support for profile with ARB_timer_query
and without GL_EXT_timer_query.
It's probably trivial to add support for GL_EXT_disjoint_timer_query given
it looks like a super set of ARB_timer_query. Actually, doing this
diff --git a/retrace/glretrace_main.cpp b/retrace/glretrace_main.cpp
index 0282929..917d3df 100755
--- a/retrace/glretrace_main.cpp
+++ b/retrace/glretrace_main.cpp
@@ -291,7 +291,7 @@ initContext() {
/* Ensure we have adequate extension support */
assert(currentContext);
- supportsTimestamp =
currentContext->hasExtension("GL_ARB_timer_query");
+ supportsTimestamp =
currentContext->hasExtension("GL_ARB_timer_query") ||
currentContext->hasExtension("EXT_disjoint_timer_query");
supportsElapsed =
currentContext->hasExtension("GL_EXT_timer_query") || supportsTimestamp;
supportsOcclusion =
currentContext->hasExtension("GL_ARB_occlusion_query");
supportsDebugOutput =
currentContext->hasExtension("GL_ARB_debug_output");
might be good enough.
