[Piglit] [PATCH 2/2] ARB_sync: Add two new tests of glClientWaitSync.

Eric Anholt eric at anholt.net
Wed May 30 12:46:39 PDT 2012


The second one catches the failure of the intel driver to actually
implement the timeout.

+ *
+ * From the GL_ARB_sync spec:
+ *
+ *     "If <sync> is signaled at the time ClientWaitSync is called
+ *      then ClientWaitSync returns immediately. If <sync> is
+ *      unsignaled at the time ClientWaitSync is called then
+ *      ClientWaitSync will block and will wait up to <timeout>
+ *      nanoseconds for <sync> to become signaled.
+ *
+ *      ...
+ *
+ *      ALREADY_SIGNALED will always be returned if <sync> was
+ *      signaled, even if the value of <timeout> is zero."
+ *
+ * There was concern that the implementation of the kernel API on i965
+ * might violate this for the specific case of back-to-back
+ * ClientWaitSyncs, but Mesa core doesn't end up calling into the
+ * driver on a later ClientWaitSync.
