+/* Sun4v hypervisor interfaces and defines.
+ *
+ * Hypervisor calls are made via traps to software traps number 0x80
+ * and above. Registers %o0 to %o5 serve as argument, status, and
+ * return value registers.
+ *
+ * There are two kinds of these traps. First there are the normal
+ * "fast traps" which use software trap 0x80 and encode the function
+ * to invoke by number in register %o5. Argument and return value
+ * handling is as follows:
+ *
+ * -----------------------------------------------
+ * | %o5 | function number | undefined |
+ * | %o0 | argument 0 | return status |
+ * | %o1 | argument 1 | return value 1 |
+ * | %o2 | argument 2 | return value 2 |
+ * | %o3 | argument 3 | return value 3 |
+ * | %o4 | argument 4 | return value 4 |
+ * -----------------------------------------------
+ *
+ * The second type are "hyper-fast traps" which encode the function
+ * number in the software trap number itself. So these use trap
+ * numbers > 0x80. The register usage for hyper-fast traps is as
+ * follows:
+ *
+ * -----------------------------------------------
+ * | %o0 | argument 0 | return status |
+ * | %o1 | argument 1 | return value 1 |
+ * | %o2 | argument 2 | return value 2 |
+ * | %o3 | argument 3 | return value 3 |
+ * | %o4 | argument 4 | return value 4 |
+ * -----------------------------------------------
+ *
+ * Registers providing explicit arguments to the hypervisor calls
+ * are volatile across the call. Upon return their values are
+ * undefined unless explicitly specified as containing a particular
+ * return value by the specific call. The return status is always
+ * returned in register %o0, zero indicates a successful execution of
+ * the hypervisor call and other values indicate an error status as
+ * defined below. So, for example, if a hyper-fast trap takes
+ * arguments 0, 1, and 2, then %o0, %o1, and %o2 are volatile across
+ * the call and %o3, %o4, and %o5 would be preserved.
+ *
+ * If the hypervisor trap is invalid, or the fast trap function number
+ * is invalid, HV_EBADTRAP will be returned in %o0. Also, all 64-bits
+ * of the argument and return values are significant.

+ * must be zero.
+ *
+ * tsbindex TSB index. Identifies which entry in the TSB

+ * tsbnum and bits 31:00 contain the tsbindex.
+ *
+ * Use the HV_PCI_TSBID() macro to construct such

+ *
+ * io_attributes IO attributes for IOMMU mappings. One of more
+ * of the attritbute bits are stores in a 64-bit
+ * value. The values are defined below.
+ *
+ * r_addr 64-bit real address
+ *
+ * pci_device PCI device address. A PCI device address identifies
+ * a specific device on a specific PCI bus segment.
+ * A PCI device address ia a 32-bit unsigned integer
+ * with the following format:
+ *
+ * 00000000.bbbbbbbb.dddddfff.00000000
+ *
+ * Use the HV_PCI_DEVICE_BUILD() macro to construct
+ * such values.
+ *
+ * pci_config_offset
+ * PCI configureation space offset. For conventional
+ * PCI a value between 0 and 255. For extended
+ * configuration space, a value between 0 and 4095.
+ *
+ * Note: For PCI configuration space accesses, the offset
+ * must be aligned to the access size.
+ *
+ * error_flag A return value which specifies if the action succeeded
+ * or failed. 0 means no error, non-0 means some error
+ * occurred while performing the service.
+ *
+ * io_sync_direction
+ * Direction definition for pci_dma_sync(), defined
+ * below in HV_PCI_SYNC_*.
+ *

+ * io_page_list_p A pointer to an io_page_list.
+ *
+ * "size based byte swap" - Some functions do size based byte swapping
