-/* 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.

- *
- * 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 A list of io_page_addresses, an io_page_address is
- * a real address.
- *
- * io_page_list_p A pointer to an io_page_list.
- *
- * "size based byte swap" - Some functions do size based byte swapping
- * which allows sw to access pointers and
- * counters in native form when the processor
- * operates in a different endianness than the
- * IO bus. Size-based byte swapping converts a
- * multi-byte field between big-endian and
- * little-endian format.
