+/* 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.

+ *
+ * A guest uses this API to set a watchdog timer. Once the gues has set

+ * 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

+/* PCI IO services.
+ *
+ * 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
+ * multi-byte field between big-endian and
+ * little-endian format.

+ * branch, the chip can stop executing instructions until a trap occurs.
+ * Therefore, if interrupts are disabled, the chip can hang forever.
+ *
+ * It used to be believed that the memory barrier had to be right in the
+ * delay slot, but a case has been traced recently wherein the memory barrier
+ * was one instruction after the branch delay slot and the chip still hung.
+ * The offending sequence was the following in sym_wakeup_done() of the
+ * sym53c8xx_2 driver:
+ *
+ * call sym_ccb_from_dsa, 0
+ * movge %icc, 0, %l0
+ * brz,pn %o0, .LL1303
+ * mov %o0, %l2
+ * membar #LoadLoad
+ *
+ * The branch has to be mispredicted for the bug to occur. Therefore, we put
+ * the memory barrier explicitly into a "branch always, predicted taken"
+ * delay slot to avoid the problem case.

+ * comparison TAG based upon the virtual address and context which
+ * faults.
+ *
+ * TLB miss trap handler software does the actual lookup via something

+ * -------------------------------------------------
+ * 63 61 60 48 47 42 41 0

+ * field.
+ *
+ * Like the powerpc hashtables we need to use locking in order to
+ * synchronize while we update the entries. PTE updates need locking
+ * as well.
+ *
+ * We need to carefully choose a lock bits for the TSB entry. We
+ * choose to use bit 47 in the tag. Also, since we never map anything

+/* Before touching these macros, you owe it to yourself to go and
+ * see how arch/sparc64/kernel/winfixup.S works... -DaveM
+ *
+ * For the user cases we used to use the %asi register, but
+ * it turns out that the "wr xxx, %asi" costs ~5 cycles, so
+ * now we use immediate ASI loads and stores instead. Kudos
+ * to Greg Onufer for pointing out this performance anomaly.
+ *
+ * Further note that we cannot use the g2, g4, g5, and g7 alternate
+ * globals in the spill routines, check out the save instruction in
+ * arch/sparc64/kernel/etrap.S to see what I mean about g2, and
+ * g4/g5 are the globals which are preserved by etrap processing
+ * for the caller of it. The g7 register is the return pc for
+ * etrap. Finally, g6 is the current thread register so we cannot
+ * us it in the spill handlers either. Most of these rules do not
+ * apply to fill processing, only g6 is not usable.
