| |
| Extension Type |
| |
| EGL device extension |
| |
| Dependencies |
| |
| This extension is written against the language of EGL 1.5 as |
| modified by EGL_EXT_device_base. |
| |
| EGL_EXT_device_base is required. |
| |
| Overview |
| |
| EGL and CUDA both have the capability to drive multiple devices, |
| such as GPUs, within a single system. To interoperate with one |
| another, both APIs must have compatible notions of such devices. |
| This extension defines a mapping from an EGL device to a CUDA device |
| enumerant. |

| |
| New Tokens |
| |
| Accepted as a queried <attribute> in eglQueryDeviceAttribEXT: |
| |
| EGL_CUDA_DEVICE_NV 0x323A |
| |
| Add a new section 2.1.3 (CUDA Devices) after 2.1.2 (Devices) |
| |
| "Somewhat analogous to an EGL device, a CUDA device establishes a |
| namespace for CUDA operations. In the CUDA API, such a device is |
| represented by a C int. For more details, see the CUDA |
| documentation." |
| |
| Changes to section 3.2 (Device Enumeration) |
| |
| Replace the paragraph immediately following the prototype for |
| eglQueryDeviceAttribEXT: |
| |
| "The only valid value of <attribute> is EGL_CUDA_DEVICE_NV. On |
| success, EGL_TRUE is returned, and a valid CUDA device handle |
| corresponding to the EGL device is returned in <value>. This handle |
| is compatible with CUDA API functions." |
