hv_vcpu_set_sme_za_reg(_:_:_:)

Declaration

func hv_vcpu_set_sme_za_reg(_ vcpu: hv_vcpu_t, _ value: UnsafePointer<UInt8>, _ length: Int) -> hv_return_t

Parameters

• vcpu:

  The ID of the vCPU instance.

• value:

  A pointer to the register value to set.

• length:

  The length of the provided ZA register value, in bytes.

Return Value

HV_SUCCESS on success, an error code otherwise.

Discussion

This method returns an error if PSTATE.ZA is 0 (for example, if za_storage_enabled is false), or if the value length isn’t the range of [maximum of SVL bytes * maximum SVL bytes].

This methods doesn’t require streaming SVE mode to be in an enabled state.
