+/* The Niagara2 RNG provides a 64-bit read-only random number
+ * register, plus a control register. Access to the RNG is
+ * virtualized through the hypervisor so that both guests and control
+ * nodes can access the device.
+ *
+ * The entropy source consists of raw entropy sources, each
+ * constructed from a voltage controlled oscillator whose phase is
+ * jittered by thermal noise sources.
+ *
+ * The oscillator in each of the three raw entropy sources run at
+ * different frequencies. Normally, all three generator outputs are
+ * gathered, xored together, and fed into a CRC circuit, the output of
+ * which is the 64-bit read-only register.
+ *
+ * Some time is necessary for all the necessary entropy to build up
+ * such that a full 64-bits of entropy are available in the register.
+ * In normal operating mode (RNG_CTL_LFSR is set), the chip implements
+ * an interlock which blocks register reads until sufficient entropy
+ * is available.
+ *
+ * A control register is provided for adjusting various aspects of RNG
+ * operation, and to enable diagnostic modes. Each of the three raw
+ * entropy sources has an enable bit (RNG_CTL_ES{1,2,3}). Also
+ * provided are fields for controlling the minimum time in cycles
+ * between read accesses to the register (RNG_CTL_WAIT, this controls
+ * the interlock described in the previous paragraph).
+ *
+ * The standard setting is to have the mode bit (RNG_CTL_LFSR) set,
+ * all three entropy sources enabled, and the interlock time set
+ * appropriately.
+ *
+ * The CRC polynomial used by the chip is:
+ *
+ * P(X) = x64 + x61 + x57 + x56 + x52 + x51 + x50 + x48 + x47 + x46 +
+ * x43 + x42 + x41 + x39 + x38 + x37 + x35 + x32 + x28 + x25 +
+ * x22 + x21 + x17 + x15 + x13 + x12 + x11 + x7 + x5 + x + 1
+ *
+ * The RNG_CTL_VCO value of each noise cell must be programmed
+ * seperately. This is why 4 control register values must be provided
+ * to the hypervisor. During a write, the hypervisor writes them all,
+ * one at a time, to the actual RNG_CTL register. The first three
+ * values are used to setup the desired RNG_CTL_VCO for each entropy
+ * source, for example:
+ *
+ * control 0: (1 << RNG_CTL_VCO_SHIFT) | RNG_CTL_ES1
+ * control 1: (2 << RNG_CTL_VCO_SHIFT) | RNG_CTL_ES2
+ * control 2: (3 << RNG_CTL_VCO_SHIFT) | RNG_CTL_ES3
+ *
+ * And then the fourth value sets the final chip state and enables
+ * desired.

+/* 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.

+ * 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

+ *
+ * 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

+ *
+ * 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

+ *
+ * Use the HV_PCI_DEVICE_BUILD() macro to construct

+ * configuration space, a value between 0 and 4095.
+ *
+ * Note: For PCI configuration space accesses, the offset
+ * must be aligned to the access size.

+/* Before touching these macros, you owe it to yourself to go and

+ *
+ * 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.

-/* 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

- *
- * 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.

-/* 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.

- * movge %icc, 0, %l0
- * brz,pn %o0, .LL1303

-/* The sparc64 TSB is similar to the powerpc hashtables. It's a
- * power-of-2 sized table of TAG/PTE pairs. The cpu precomputes
- * pointers into this table for 8K and 64K page sizes, and also a
- * comparison TAG based upon the virtual address and context which
- * faults.
- *
- * TLB miss trap handler software does the actual lookup via something
- * of the form:
- *
- * ldxa [%g0] ASI_{D,I}MMU_TSB_8KB_PTR, %g1
- * ldxa [%g0] ASI_{D,I}MMU, %g6

- * mov FAULT_CODE_{D,I}TLB, %g3
- * stxa %g5, [%g0] ASI_{D,I}TLB_DATA_IN
- * retry
- *
- *
- * Each 16-byte slot of the TSB is the 8-byte tag and then the 8-byte
- * PTE. The TAG is of the same layout as the TLB TAG TARGET mmu
- * register which is:
- *
- * -------------------------------------------------
- * | - | CONTEXT | - | VADDR bits 63:22 |
- * -------------------------------------------------
- * 63 61 60 48 47 42 41 0
- *
- * But actually, since we use per-mm TSB's, we zero out the CONTEXT
- * 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
- * at page zero in context zero, we use zero as an invalid tag entry.
- * When the lock bit is set, this forces a tag comparison failure.

-/* 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.
