Any address passed to SAL as buffers 27 for return parameters must be 8-byte aligned. Unaligned 28 addresses may cause undefined results. For those parameters 29 defined as reserved or some fields defined as reserved must be 30 zero filled or the invalid argument return value may be returned 31 or undefined result may occur during the execution of the procedure. 32 This function is only available on Intel Itanium-based platforms. 33 34 @param Index The SAL procedure Index number 35 @param Arg2 The 2nd parameter for SAL procedure calls 36 @param Arg3 The 3rd parameter for SAL procedure calls 37 @param Arg4 The 4th parameter for SAL procedure calls 38 @param Arg5 The 5th parameter for SAL procedure calls 39 @param Arg6 The 6th parameter for SAL procedure calls 40 @param Arg7 The 7th parameter for SAL procedure calls 41 @param Arg8 The 8th parameter for SAL procedure calls 42 43 @return SAL returned registers. 44 45 **/ 46 SAL_RETURN_REGS 47 EFIAPI 48 SalCall ( 49 IN UINT64 Index, 50 IN UINT64 Arg2, 51 IN UINT64 Arg3, 52 IN UINT64 Arg4, 53 IN UINT64 Arg5, 54 IN UINT64 Arg6, 55 IN UINT64 Arg7, 56 IN UINT64 Arg8 57 ); 58 59 #endif 60
