| OpenCL Extension #7 |
| |
| Status |
| |
| Complete, shipping as part of ATi Stream SDK 3.1 |
| |
| Extension Type |
| |
| OpenCL device extension. |
| |
| Dependencies |
| |
| OpenCL 1.2 is required. |
| |
| Overview |
| |
| This extension provides a means to query AMD specific device attributes. |
| |
| Implementers should note that the enum |
| CL_DEVICE_SIMD_PER_COMPUTE_UNIT_AMD has the same numeric value, 0x4040, |
| as the enum CL_COMMAND_MIGRATE_MEM_OBJECT_EXT from the OpenCL 1.1 |
| extension cl_ext_migrate_memobject, but this is not expected to cause |
| any application problems. |
| |
| New Tokens |
| |
| Accepted as the <param_name> parameter of clGetDeviceInfo. |
