4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync Makes a PAL procedure call.
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync This is a wrapper function to make a PAL procedure call. Based on the Index value,
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync this API will make static or stacked PAL call. Architected procedures may be designated
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync as required or optional. If a PAL procedure is specified as optional, a unique return
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync code of 0xFFFFFFFFFFFFFFFF is returned in the Status field of the PAL_CALL_RETURN structure.
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync This indicates that the procedure is not present in this PAL implementation. It is the
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync caller's responsibility to check for this return code after calling any optional PAL
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync procedure. No parameter checking is performed on the 4 input parameters, but there are
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync some common rules that the caller should follow when making a PAL call. Any address
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync passed to PAL as buffers for return parameters must be 8-byte aligned. Unaligned addresses
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync may cause undefined results. For those parameters defined as reserved or some fields
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync defined as reserved must be zero filled or the invalid argument return value may be
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync returned or undefined result may occur during the execution of the procedure.

4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync @param Index The PAL procedure Index number.
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync @param Arg2 The 2nd parameter for PAL procedure calls.
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync @param Arg3 The 3rd parameter for PAL procedure calls.
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync @param Arg4 The 4th parameter for PAL procedure calls.
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync @return Structure returned from the PAL Call procedure, including the status and return value.
