21 | Makes a SAL procedure call.\r | |
22 | \r | |
23 | This is a wrapper function to make a SAL procedure call. \r | |
24 | No parameter checking is performed on the 8 input parameters,\r | |
25 | but there are some common rules that the caller should follow\r | |
26 | when making a SAL call. Any address passed to SAL as buffers\r | |
27 | for return parameters must be 8-byte aligned. Unaligned\r | |
28 | addresses may cause undefined results. For those parameters\r | |
29 | defined as reserved or some fields defined as reserved must be\r | |
30 | zero filled or the invalid argument return value may be returned\r | |
31 | or undefined result may occur during the execution of the procedure.\r | |
1a2f870c | 32 | This function is only available on Intel Itanium-based platforms.\r |
