| 32 | * GEN8 brings an expansion of the HW contexts: "Logical Ring Contexts". |
| 33 | * These expanded contexts enable a number of new abilities, especially |
| 34 | * "Execlists" (also implemented in this file). |
| 35 | * |
| 36 | * Execlists are the new method by which, on gen8+ hardware, workloads are |
| 37 | * submitted for execution (as opposed to the legacy, ringbuffer-based, method). |
