Add BasePalCallLibNull instance in MdePkg. It is useful when building IPF components in open source packages.
Use meaningful arguments defined in PalLib.h when invoking PalCall(). git-svn-id: https://edk2.svn.sourceforge.net/svnroot/edk2/trunk/edk2@4094 6f19259b-4bc3-4df7-8a09-765794883524

/**
|
||||
Makes a PAL procedure call.
|
||||
|
||||
This is a wrapper function to make a PAL procedure call. Based on the Index value,
|
||||
this API will make static or stacked PAL call. Architected procedures may be designated
|
||||
as required or optional. If a PAL procedure is specified as optional, a unique return
|
||||
code of 0xFFFFFFFFFFFFFFFF is returned in the Status field of the PAL_CALL_RETURN structure.
|
||||
This indicates that the procedure is not present in this PAL implementation. It is the
|
||||
caller¡¯s responsibility to check for this return code after calling any optional PAL
|
||||
procedure. No parameter checking is performed on the 4 input parameters, but there are
|
||||
some common rules that the caller should follow when making a PAL call. Any address
|
||||
passed to PAL as buffers for return parameters must be 8-byte aligned. Unaligned addresses
|
||||
may cause undefined results. For those parameters defined as reserved or some fields
|
||||
defined as reserved must be zero filled or the invalid argument return value may be
|
||||
returned or undefined result may occur during the execution of the procedure.
|
||||
This function is only available on IPF.
|
||||
|
||||
@param Index - The PAL procedure Index number.
|
||||
@param Arg2 - The 2nd parameter for PAL procedure calls.
|
||||
@param Arg3 - The 3rd parameter for PAL procedure calls.
|
||||
@param Arg4 - The 4th parameter for PAL procedure calls.
|
||||
|
||||
