| 1003 | * Save all Gunit registers that may be lost after a D3 and a subsequent |
| 1004 | * S0i[R123] transition. The list of registers needing a save/restore is |
| 1005 | * defined in the VLV2_S0IXRegs document. This documents marks all Gunit |
| 1006 | * registers in the following way: |
| 1007 | * - Driver: saved/restored by the driver |
| 1008 | * - Punit : saved/restored by the Punit firmware |
| 1009 | * - No, w/o marking: no need to save/restore, since the register is R/O or |
| 1010 | * used internally by the HW in a way that doesn't depend |
| 1011 | * keeping the content across a suspend/resume. |
| 1012 | * - Debug : used for debugging |
| 1013 | * |
| 1014 | * We save/restore all registers marked with 'Driver', with the following |
| 1015 | * exceptions: |
| 1016 | * - Registers out of use, including also registers marked with 'Debug'. |
| 1017 | * These have no effect on the driver's operation, so we don't save/restore |
| 1018 | * them to reduce the overhead. |
| 1019 | * - Registers that are fully setup by an initialization function called from |
| 1020 | * the resume path. For example many clock gating and RPS/RC6 registers. |
| 1021 | * - Registers that provide the right functionality with their reset defaults. |
| 1022 | * |
| 1023 | * TODO: Except for registers that based on the above 3 criteria can be safely |
| 1024 | * ignored, we save/restore all others, practically treating the HW context as |
| 1025 | * a black-box for the driver. Further investigation is needed to reduce the |
| 1026 | * saved/restored registers even further, by following the same 3 criteria. |
