Terminates operation of the virtual processor specified by vpd on the logical processor.
Description:
The host virtual to host physical translation of the 64K region specified by vpd must be
mapped by instruction and data translation registers (TR). See
"Making PAL Procedure Calls in Physical or Virtual Mode" on page 2:359
data translation requirements of memory buffer pointers passed as arguments to PAL
procedures. All resources allocated for the execution of the virtual machine are freed.
Upon successful execution of PAL_VP_TERMINATE procedure and if the iva parameter is
non-zero, the IVA control register will contain the value from the iva parameter.
This procedure returns unimplemented procedure when virtual machine features are
disabled. See
"PAL_PROC_GET_FEATURES – Get Processor Dependent Features (17)" on page 2:446
for details.
