| * ARM_SMCCC_VENDOR_HYP_KVM_GET_CUR_CPUFREQ_FUNC_ID: 0x86000041 |
| |
| This hypercall uses the SMC32/HVC32 calling convention: |
| |
| ARM_SMCCC_VENDOR_HYP_KVM_GET_CUR_CPUFREQ_FUNC_ID |
| ============== ======== ===================================== |
| Function ID: (uint32) 0x86000041 |
| Return Values: (int32) NOT_SUPPORTED(-1) on error, or |
| (uint32) Frequency in KHz of current CPU that the |
| vCPU thread is running on. |
