| 2346 | * On CIK, gfx and compute now have independant command processors. |
| 2347 | * |
| 2348 | * GFX |
| 2349 | * Gfx consists of a single ring and can process both gfx jobs and |
| 2350 | * compute jobs. The gfx CP consists of three microengines (ME): |
| 2351 | * PFP - Pre-Fetch Parser |
| 2352 | * ME - Micro Engine |
| 2353 | * CE - Constant Engine |
| 2354 | * The PFP and ME make up what is considered the Drawing Engine (DE). |
| 2355 | * The CE is an asynchronous engine used for updating buffer desciptors |
| 2356 | * used by the DE so that they can be loaded into cache in parallel |
| 2357 | * while the DE is processing state update packets. |
| 2358 | * |
| 2359 | * Compute |
| 2360 | * The compute CP consists of two microengines (ME): |
| 2361 | * MEC1 - Compute MicroEngine 1 |
| 2362 | * MEC2 - Compute MicroEngine 2 |
| 2363 | * Each MEC supports 4 compute pipes and each pipe supports 8 queues. |
| 2364 | * The queues are exposed to userspace and are programmed directly |
| 2365 | * by the compute runtime. |
