| 21 | Makes a SAL procedure call.
|
|---|
| 22 |
|
|---|
| 23 | This is a wrapper function to make a SAL procedure call.
|
|---|
| 24 | No parameter checking is performed on the 8 input parameters,
|
|---|
| 25 | but there are some common rules that the caller should follow
|
|---|
| 26 | when making a SAL call. 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.
