| PURPOSE = """ |
| Verify that sync control extensions allow us to track when vsyncs occur. |
| """ |
| CRITERIA = """ |
| This test will fail if the reported interval between vsyncs differs from the |
| expected values by more then 200 uS. The expected value is derived from the |
| refresh rate, Hz, of the screen. |
| """ |
| DOC = """ |
| This test in a loop sets up the screen to draw a single colour, records current |
| sync values, calls swap buffers, and then sleeps for maxium expected time for a |
| vsync. On waking up the sync values will be queried again. The two different |
| sync values are used to determine how much time the extension is reporting |
| between vsync. |
| |
| This test will fail if the reported interval between vsyncs differs from the |
| expected values by more then 200 uS. The expected value is derived from the |
| refresh rate, Hz, of the screen. |
| |
| Currently this test only executes on EGL devices, daisy, since this is the |
| situation where we have written new prototype code. The GLX side currently is a |
| no-op that will always succeed. |
