Fence sync tests
Tests:
+ dEQP-GLES3.functional.fence_sync.*
Includes:
+ Creating and deleting sync objects
+ Calling glWaitSync
- With varying number of primitive draws
+ Calling glClientWaitSync and verifying return values
- With varying number of primitive draws
- With varying timeouts
- Flushing or finishing before wait
Description:
Fence sync functionality is tested by drawing a small or large number of
primitives with glDrawArrays(). Then a sync object is created, and
optionally glFlush() or glFinish() are called.
Wait is then performed with either glWaitSync() or glClientWaitSync(), and
different timeout values as well as the flag GL_SYNC_FLUSH_COMMANDS_BIT
are tested. Finally, errors are checked and the return value of
glClientWaitSync() is verified.
The testcase fails if errors are created or if glClientWaitSync() returns
GL_WAIT_FAILED. Additionally, if glFinish() was called before wait, return
value is required to be GL_ALREADY_SIGNALED.
