| * Maximum PB free list size supported by RGX and Services. |
| * |
| * Maximum PB free list size must ensure that no PM address space can be fully |
| * used, because if the full address space was used it would wrap and corrupt |
| * itself. Since there are two freelists (local is always minimum sized) this |
| * can be described as following three conditions being met: |
| * |
| * Minimum PB + Maximum PB < ALIST PM address space size (16GB) |
| * Minimum PB + Maximum PB < TE PM address space size (16GB) / NUM_TE_PIPES |
| * Minimum PB + Maximum PB < VCE PM address space size (16GB) / NUM_VCE_PIPES |
| * |
| * Since the max of NUM_TE_PIPES and NUM_VCE_PIPES is 4, we have a hard limit |
| * of 4GB minus the Minimum PB. For convenience we take the smaller power-of-2 |
| * value of 2GB. This is far more than any normal application would request |
| * or use. |
