| OpenGL ES Extension #56 |
| |
| Dependencies |
| |
| This extension interacts with AMD_performance_monitor. |
| |
| Overview |
| |
| This extension introduces a global tracking mode in the performance |
| monitors. When enabled, the counters increment in all operations, |
| including all "housekeeping" operations such as resolves/clears and |
| operations performed by other concurrent applications. The normal |
| operation is to track only the application's own operations. |
| |
| Issues |
| |
| (1) How do we filter operations from other applications? |
| |
| RESOLVED: We don't. The user of this extension should be aware of the |
| consequences. |
| |
| (2) What should happen if the global mode is enabled or disabled while |
| the performance monitors are in use? |
| |
| RESOLVED: The results in this case are undefined. |
| |
| New Tokens |
| |
| Accepted by the <cap> parameter of Enable and Disable, and |
| IsEnabled, and by the <pname> parameter of GetBooleanv, GetIntegerv, |
| and GetFloatv: |
| |
| PERFMON_GLOBAL_MODE_QCOM 0x8FA0 |
| |
| New Procedures and Functions |
| |
| None. |
| |
| Addition to the GL specification |
| |
| Add this to the Performance Monitoring section that was added by |
| AMD_performance_monitor: |
| |
| "A global tracking mode can be enabled and disabled with the generic |
| Enable and Disable commands using the symbolic constant |
| PERFMON_GLOBAL_MODE_QCOM. When enabled the counters increment in all |
| operations, contexts, and other applications using the hardware." |
| |
| Errors |
| |
| None |
| |
| Sample Usage |
| |
| // Activate global performance monitor tracking |
| glEnable(GL_PERFMON_GLOBAL_MODE_QCOM); |
