12  * - Low bandwidth (LB) hypercalls (I/O port based, vmcall and vmmcall)
17  * arg0 - VMWARE_HYPERVISOR_MAGIC
18  * arg2 - Hypercall command
19  * arg3 bits [15:0] - Port number, LB and direction flags
21  * - Low bandwidth TDX hypercalls (x86_64 only) are similar to LB
27  * - High bandwidth (HB) hypercalls are I/O port based only. They have
32  * arg0 - VMWARE_HYPERVISOR_MAGIC
33  * arg1 - Hypercall command
34  * arg3 bits [15:0] - Port number, HB and direction flags
39  * The hypercall definitions differ in the low word of the %edx (arg3)
41  * number to distinguish between high- and low bandwidth versions, and
45  * bandwidth mode and transfer direction. The flags should be loaded
66  *   bits [19:16] sub-command, range [0, 15]
89  * The low bandwidth call. The low word of %edx is presumed to have OUT bit
263  * High bandwidth calls are not supported on encrypted memory guests.
265  * low bandwidth hypercall if memory encryption is set.
