| /* 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. |

| * ARG0: timeout in milliseconds |
| * RET0: status |
| * RET1: time remaining in milliseconds |
| * |
| * A guest uses this API to set a watchdog timer. Once the gues has set |
| * the timer, it must call the timer service again either to disable or |
| * postpone the expiration. If the timer expires before being reset or |
| * disabled, then the hypervisor take a platform specific action leading |
| * to guest termination within a bounded time period. The platform action |
| * may include recovery actions such as reporting the expiration to a |
| * Service Processor, and/or automatically restarting the gues. |
| * |
| * The 'timeout' parameter is specified in milliseconds, however the |
| * implementated granularity is given by the 'watchdog-resolution' |
| * property in the 'platform' node of the guest's machine description. |
| * The largest allowed timeout value is specified by the |
| * 'watchdog-max-timeout' property of the 'platform' node. |
| * |
| * If the 'timeout' argument is not zero, the watchdog timer is set to |
| * expire after a minimum of 'timeout' milliseconds. |
| * |
| * If the 'timeout' argument is zero, the watchdog timer is disabled. |
| * |
| * If the 'timeout' value exceeds the value of the 'max-watchdog-timeout' |
| * property, the hypervisor leaves the watchdog timer state unchanged, |
| * and returns a status of EINVAL. |
| * |
| * The 'time remaining' return value is valid regardless of whether the |
| * return status is EOK or EINVAL. A non-zero return value indicates the |
| * number of milliseconds that were remaining until the timer was to expire. |
| * If less than one millisecond remains, the return value is '1'. If the |
| * watchdog timer was disabled at the time of the call, the return value is |
| * zero. |
| * |
| * If the hypervisor cannot support the exact timeout value requested, but |
| * can support a larger timeout value, the hypervisor may round the actual |
| * timeout to a value larger than the requested timeout, consequently the |
| * 'time remaining' return value may be larger than the previously requested |
| * timeout value. |
| * |
| * Any guest OS debugger should be aware that the watchdog service may be in |
| * use. Consequently, it is recommended that the watchdog service is |
| * disabled upon debugger entry (e.g. reaching a breakpoint), and then |
| * re-enabled upon returning to normal execution. The API has been designed |
| * with this in mind, and the 'time remaining' result of the disable call may |
| * be used directly as the timeout argument of the re-enable call. |

| * |
| * See the terminology descriptions in the device interrupt services |
| * section above as those apply here too. Here are terminology |
| * definitions specific to these PCI IO services: |
| * |
| * tsbnum TSB number. Indentifies which io-tsb is used. |
| * For this version of the specification, tsbnum |
| * must be zero. |
| * |
| * tsbindex TSB index. Identifies which entry in the TSB |
| * is used. The first entry is zero. |
| * |
| * tsbid A 64-bit aligned data structure which contains |
| * a tsbnum and a tsbindex. Bits 63:32 contain the |
| * tsbnum and bits 31:00 contain the tsbindex. |
| * |
| * Use the HV_PCI_TSBID() macro to construct such |
| * values. |
| * |
| * 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 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 |
