| ============================ |
| |
| Util_hint is used for sharing the utilization value from the guest |
| to the host. |

| * ARM_SMCCC_HYP_KVM_UTIL_HINT_FUNC_ID: 0x86000042 |
| |
| This hypercall using the SMC32/HVC32 calling convention: |
| |
| ARM_SMCCC_HYP_KVM_UTIL_HINT_FUNC_ID |
| ============== ========= ============================ |
| Function ID: (uint32) 0x86000042 |
| Arguments: (uint32) util value(0-1024) where 1024 represents |
| the highest performance point normalized |
| across all CPUs |
| Return values: (int32) NOT_SUPPORTED(-1) on error. |
| Endianness: Must be the same endianness |
| as the host. |
