| * of performance event, the following trick is used. |
| * |
| * 1) Since both ESCR and CCCR registers have only low |
| * 32 bits valuable, we pack them into a single 64 bit |
| * configuration. Low 32 bits of such config correspond |
| * to low 32 bits of CCCR register and high 32 bits |
| * correspond to low 32 bits of ESCR register. |

| * be found in Intel SDM but it should be noted that |
| * we "borrow" some reserved bits for own usage and |
| * clean them or set to a proper value when we do |
| * a real write to hardware registers. |
| * |
| * 3) The format of bits of config is the following |
| * and should be either 0 or set to some predefined |
| * values: |
| * |
