| [ Upstream commit b0b13d532105e0e682d95214933bb8483a063184 ] |
| |
| Make SVM BOs more likely to get evicted than other BOs. These BOs |
| opportunistically use available VRAM, but can fall back relatively |
| seamlessly to system memory. It also avoids SVM migrations evicting |
| other, more important BOs as they will evict other SVM allocations |
| first. |
