/*
** Time Related Type Definitions
**
** An HPI time value represents the local time as the number of nanoseconds 
** from 00:00:00, January 1, 1970, in a 64-bit signed integer. This format
** is sufficient to represent times with nano-second resolution from the
** year 1678 to 2262. Every API which deals with time values must define
** the timezone used.
**
** It should be noted that although nano-second resolution is supported
** in the data type, the actual resolution provided by an implementation
** may be more limited than this.
**
** The value -2**63, which is 0x8000000000000000, is used to indicate
** "unknown/unspecified time".
** 
** Conversion to/from POSIX and other common time representations is
** relatively straightforward. The following code framgment converts 
** between SaHpiTimeT and time_t:
** 
**     time_t tt1, tt2;
**     SaHpiTimeT saHpiTime;
**     
**     time(&tt1);
**     saHpiTime = (SaHpiTimeT) tt1 * 1000000000;
**     tt2 = saHpiTime / 1000000000;
**
** The following fragment converts between SaHpiTimeT and a struct timeval:
**
**     struct timeval tv1, tv2;
**     SaHpiTimeT saHpiTime;
**     
**     gettimeofday(&tv1, NULL);
**     saHpiTime = (SaHpiTimeT) tv1.tv_sec * 1000000000 + tv1.tv_usec * 1000;
**     tv2.tv_sec = saHpiTime / 1000000000;
**     tv2.tv_usec = saHpiTime % 1000000000 / 1000;
**
** The following fragment converts between SaHpiTimeT and a struct timespec:
**
**     struct timespec ts1, ts2;
**     SaHpiTimeT saHpiTime;
**     
**     clock_gettime(CLOCK_REALTIME, &ts1);
**     saHpiTime = (SaHpiTimeT) ts1.tv_sec * 1000000000 + ts1.tv_nsec;
**     ts2.tv_sec = saHpiTime / 1000000000;
**     ts2.tv_nsec = saHpiTime % 1000000000;
**
** Note, however, that since time_t is (effectively) universally 32 bits,
** all of these conversions will cease to work on January 18, 2038.
** 
** Some subsystems may need the flexibility to report either absolute or
** relative (eg. to system boot) times. This will typically be in the
** case of a board which may or may not, depending on the system setup,
** have an idea of absolute time. For example, some boards may have
** "time of day" clocks which start at zero, and never get set to the
** time of day.
**
** In these cases, times which represent "current" time (in events, for
** example) can be reported based on the clock value, whether it has been
** set to the actual date/time, or whether it represents the elapsed time
** since boot. If it is the time since boot, the value will be (for 27
** years) less than 0x0C00000000000000, which is Mon May 26 16:58:48 1997.
** If the value is greater than this, then it can be assumed to be an
** absolute time.
**
** Every API which can report either absolute or relative times must
** state this rule clearly in its interface specification.

** is designated with an Entity Type of SAHPI_ENT_ROOT if the entire Entity Path 
** is fewer than SAHPI_MAX_ENTITY_PATH entries in length.
**
** Enumerated Entity Types include those types enumerated by the IPMI Consortium
** for IPMI-managed entities, as well as additional types defined by the

** predefined conversion from raw to interpreted and the sensor factors may or

** For other linearization values, raw readings may be converted to interpreted 
** values using the formula:
**Interpreted = L [( M*raw + B*10^ExpB )*10^ExpR ]  
**where "L[x]" is the indicated linearization function  
** (for SAHPI_SL_LINEAR, L[x]=x).
** The Tolerance Factor is given as +/- 1/2 raw counts, so tolerance in 
** interpreted values can be calculated as:
** L[ M * ToleranceFactor/2 * 10^ExpR ]
** The Accuracy Factor is given as 1/100 of a percent, scaled up by ExpA. Thus 
** the accuracy is:  
**( ( AccuracyFactor/100 ) / 10^ExpA )%

** Watchdog Structure
** 
** This structure is used by the saHpiWatchdogTimerGet() and  
** saHpiWatchdogTimerSet() functions. The use of the structure varies slightly by 
** each function.
**
** For saHpiWatchdogTimerGet() :
**
**   Log -                indicates whether or not the Watchdog is configured to 
**                        issue an event when it next times out. TRUE=event will 
**                        be issued on timeout.
**   Running -            indicates whether or not the Watchdog is currently 
**                        running or stopped. TRUE=Watchdog is running.
**   TimerUse -           indicates the current use of the timer; one of five 
**                        preset uses which was included on the last
**                        saHpiWatchdogTimerSet() function call, or through some 
**                        other implementation-dependent means to start the 
**                        Watchdog timer.
**   TimerAction -        indicates what action will be taken when the Watchdog 
**                        times out.
**   PretimerInterrupt -  indicates which action will be taken 
**                        "PreTimeoutInterval" seconds prior to Watchdog timer 
**                        expiration. 
**   PreTimeoutInterval - indicates how many  milliseconds prior to timer time 
**                        out the PretimerInterrupt action will be taken. If 
**                        "PreTimeoutInterval" = 0, the PretimerInterrupt action 
**                        will occur concurrently with "TimerAction." HPI 
**                        implementations may not be able to support millisecond 
**                        resolution and may have a maximum value restriction. 
**                        These restrictions should be documented by the 
**                        provider of the HPI interface.
**   TimerUseExpFlags -   set of five bit flags which indicate that a Watchdog 
**                        timer timeout has occurred while the corresponding 
**                        TimerUse value was set. Once set, these flags stay 
**                        set until specifically cleared with a 
**                        saHpiWatchdogTimerSet() call, or by some other 
**                        implementation-dependent means.
**   InitialCount -       The time, in milliseconds, before the timer will time 
**                        out after a saHpiWatchdogTimerReset() function call is
**                        made, or some other implementation-dependent strobe is
**                        sent to the Watchdog. HPI implementations may not be
**                        able to support millisecond resolution and may have a 
**                        maximum value restriction. These restrictions should 
**                        be documented by the provider of the HPI interface.
**   PresentCount -       The remaining time in milliseconds before the timer 
**                        will time out unless a saHpiWatchdogTimerReset()
**                        function call is made, or some other implementation-
**                        dependent strobe is sent to the Watchdog. 
**                        HPI implementations may not be able to support 
**                        millisecond resolution on watchdog timers, but will 
**                        return the number of clock ticks remaining times the 
**                        number of milliseconds between each tick.
**
** For saHpiWatchdogTimerSet():
**
**   Log -                indicates whether or not the Watchdog should  issue 
**                        an event when it next times out. TRUE=event will be 
**                        issued on timeout.
**   Running -            indicates whether or not the Watchdog should be 
**                        stopped before updating. 
**                        TRUE =  Watchdog is not stopped. If it is already 
**                                stopped, it will remain stopped, but if it is 
**                                running, it will continue to run, with the 
**                                countdown timer reset to the new InitialCount. 
**                                Note that there is a race condition possible 
**                                with this setting, so it should be used with 
**                                care. 
**                        FALSE = Watchdog is stopped. After 
**                                saHpiWatchdogTimerSet() is called, a subsequent 
**                                call to saHpiWatchdogTimerReset() is required to 
**                                start the timer.
**   TimerUse -           indicates the current use of the timer. Will control 
**                        which TimerUseExpFlag is set if the timer expires.
**   TimerAction -        indicates what action will be taken when the Watchdog 
**                        times out.
**   PretimerInterrupt -  indicates which action will be taken 
**                        "PreTimeoutInterval" seconds prior to  Watchdog timer 
**                        expiration. 
**   PreTimeoutInterval - indicates how many milliseconds prior to timer time 
**                        out the PretimerInterrupt action will be taken. If 
**                        "PreTimeoutInterval" = 0, the PretimerInterrupt action 
**                        will occur concurrently with "TimerAction." HPI 
**                        implementations may not be able to support millisecond 
**                        resolution and may have a maximum value restriction. 
**                        These restrictions should be documented by the 
**                        provider of the HPI interface.
**   TimerUseExpFlags -   Set of five bit flags corresponding to the five 
**                        TimerUse values. For each bit set, the corresponding 
**                        Timer Use Expiration Flag will be CLEARED. Generally, 
**                        a program should only clear the Timer Use Expiration 
**                        Flag corresponding to its own TimerUse, so that other 
**                        software, which may have used the timer for another 
**                        purpose in the past can still read its TimerUseExpFlag 
**                        to determine whether or not the timer expired during 
**                        that use.
**   InitialCount -       The time, in milliseconds, before the timer will time 
**                        out after a saHpiWatchdogTimerReset() function call is
**                        made, or some other implementation-dependent strobe is

** Name: saHpiRptEntryGet 
**
** Description:

**   read the RPT entry-by-entry. If the EntryID parameter is set to
**   SAHPI_FIRST_ENTRY, the first entry in the RPT will be returned. When
**   an entry is successfully retrieved,  *NextEntryID will be set to the
**   ID of the next valid entry; however, when the last entry has been
**   retrieved, *NextEntryID will be set to SAHPI_LAST_ENTRY. To retrieve
**   an entire list of entries, call this function first with an EntryID of
**   SAHPI_FIRST_ENTRY and then use the returned NextEntryID in the next
**   call. Proceed until the NextEntryID returned is SAHPI_LAST_ENTRY. At
**   initialization, the user may not wish to turn on eventing, since the
**   context of the events, as provided by the RPT, is not known. In this
**   instance, if a FRU is inserted into the system while the RPT is being
**   read entry by entry, the resource associated with that FRU may be
**   missed. (Keep in mind that there is no specified ordering for the RPT
**   entries.)  The update counter provides a means for insuring that no
**   resources are missed when stepping through the RPT. In order to use
**   this feature, the user should invoke saHpiRptInfoGet(), and get the
**   update counter value before retrieving the first RPT entry. After
**   reading the last entry, the user should again invoke the
**   saHpiRptInfoGet() to get the update counter value. If the update
**   counter has not been incremented, no new records have been added.   
**

** Description:
**   This function retrieves resource information from the resource

**   there may be other ways of learning resource IDs without first reading

**
** Return Value:
**   SA_OK is returned on successful completion; otherwise, an error code

**   SA_ERR_HPI_UNKNOWN is returned if the domain controller cannot
**   determine an appropriate response. That is, there may be an
**   appropriate resource ID in the domain to return, but it cannot be
**   determined. 
**
** Remarks:
**   This function must be issued within a session to a domain that
**   includes a resource associated with the entity upon which the caller
**   is running, or the SA_ERR_HPI_NOT_PRESENT return will be issued. Since
**   entities are contained within other entities, there may be multiple
**   possible resources that could be returned to this call. For example,

**   upon which the caller is running, and another associated with the
**   chassis which contains the compute blade, either could logically be
**   returned as an indication of a resource associated with the entity
**   upon which the caller was running. The function should return the
**   resource ID of the "smallest" resource that is associated with the
**   caller. So, in the example above, the function should return the
**   resource ID of the compute blade. Once the function has returned the
**   resourceID, the caller may issue further HPI calls using that
**   resourceID to learn the type of resource that been identified.

** Description:
**   This function allows the caller to get an event. This call is only
**   valid within a session, which has subscribed for events. If the
**   ProvideActiveAlarms parameter was set in the subscription, the first
**   events retrieved will reflect the state of currently active alarms for
**   the resources belonging to the domain. After all active alarms are
**   retrieved this function will begin returning newly generated events as
**   the domain controller receives them. If there are one or more events
**   on the event queue when this function is called, it will immediately
**   return the next event on the queue. Otherwise, if the Timeout
**   parameter is SAHPI_TIMEOUT_IMMEDIATE, it will return
**   SA_ERR_HPI_TIMEOUT immediately. Otherwise, it will block for a time
**   specified by the timeout parameter; if an event is added to the queue
**   within that time, it will be returned immediately; if not,
**   saHpiEventGet() will return SA_ERR_HPI_TIMEOUT. If the Timeout
**   parameter is SAHPI_TIMEOUT_BLOCK, then saHpiEventGet() will block
**   indefinitely, until an event becomes available, and then return that
**   event. This provides for notification of events as they occur. 
**
** Parameters:
**   SessionId - [in] Session for which events are retrieved. 
**   Timeout - [in] The number of nanoseconds to wait for an event to
**      arrive. Reserved time out values: SAHPI_TIMEOUT_IMMEDIATE Time out
**      immediately if there are no events available (non-blocking call).
**      SAHPI_TIMEOUT_BLOCK Call should not return until an event is
**      retrieved. 
**   Event - [out] Pointer to the next available event. 
**   Rdr - [in/out] Pointer to structure to receive the resource data
**      associated with the event. If NULL, no RDR will be returned. 
**   RptEntry - [in/out] Pointer to structure to receive the RPT entry
**      associated with the resource that generated the event. If NULL, no RPT
**      entry will be returned. 
**
** Return Value:
**   SA_OK is returned on successful completion; otherwise, an error code
**   is returned. SA_ERR_HPI_TIMEOUT is returned if no event is available
**   to return within the timeout period. If SAHPI_TIMEOUT_IMMEDIATE is
**   passed in the Timeout parameter, this error return will be used if
**   there is no event queued when the function is called. 
**
** Remarks:
**   If the caller provides a pointer for an RPT entry, but the event does
**   not include a valid resource ID for a resource in the domain (possible
**   on OEM or USER type event), then the ResourceCapabilities field in
**   *RptEntry will be set to zero. No valid RPT entry will have a zero
**   value here. If the caller provides a pointer for an RDR, but there is
**   no valid RDR associated with the event being returned (e.g., returned
**   event is not a sensor event), Rdr->RdrType will be set to
**   SAHPI_NO_RECORD. The timestamp reported in the returned event
**   structure is the best approximation an implementation has to when the
**   event actually occurred. The implementation may need to make an
**   approximation (such as the time the event was placed on the event
**   queue) because it may not have access to the actual time the event
**   occurred. The value SAHPI_TIME_UNSPECIFIED indicates that the time of
**   the event cannot be determined. If the implementation cannot supply an
**   absolute timestamp, then it may supply a timestamp relative to some
**   system-defined epoch, such as system boot. If the timestamp value is
**   less than or equal to SAHPI_TIME_MAX_RELATIVE, but not
**   SAHPI_TIME_UNSPECIFIED, then it is relative; if it is greater than
**   SAHPI_TIME_MAX_RELATIVE, then it is absolute.   6	Resource Functions

**
** Description:

**   sensor. See the SaHpiEventCategoryT definition in section 7.3,
**   "Events, Part 1," on page 83 for more information. Within the
**   structure returned, there are two elements that contain bit flags; one
**   for assertion events and one for de-assertion events. A bit set to '1'
**   in the "AssertEvents" element in the structure indicates that an event
**   will be generated when the corresponding event state changes from
**   de-asserted to asserted on that sensor. A bit set to '1' in the
**   "DeassertEvents" element in the structure indicates that an event will
**   be generated when the corresponding event state changes from asserted
**   to de-asserted on that sensor. The saHpiSensorEventEnablesGet()
**   function also returns the general sensor status - whether the sensor
**   is completely disabled, or event generation is completely disabled.

**
** Name: saHpiSensorEventEnablesSet 
**
** Description:
**   This function provides the ability to set the disable or enable event
**   message generation status for individual sensor events. The sensor
**   event states are relative to the event category specified by the
**   sensor. See the SaHpiEventCategoryT definition for more information.
**   Within the structure passed, there are two elements, which contain bit
**   flags; one for assertion events and one for de-assertion events.
**   However, the use of these two elements depends on whether the resource
**   addressed has the "SAHPI_CAPABILITY_EVT_DEASSERTS" flag set in its RPT
**   entry. This capability, if set, advertises that all sensors hosted by
**   the resource will always send a "de-assert" event when any state is
**   de-asserted whose assertion generates an "assert" event. Thus, for
**   sensors hosted by resources that advertise this behavior, it is not
**   meaningful to control assert events and de-assert events separately.
**   For sensors on resources that do not have the
**   "SAHPI_CAPABILITY_EVT_DEASSERTS" flag set, a bit set to '1' in the
**   "AssertEvents" element in the structure indicates that an event will
**   be generated when the corresponding event state changes from
**   de-asserted to asserted on that sensor., and a bit set to '1' in the
**   "DeassertEvents" element in the structure indicates that an event will
**   be generated when the corresponding event state changes from asserted
**   to de-asserted on that sensor. For sensors on resources, which do have
**   the "SAHPI_CAPABILITY_EVT_DEASSERTS" flag set, the "DeassertEvents"
**   element is not used. For sensors on these resources, a bit set to '1'
**   in the "AssertEvents" element in the structure indicates that an event
**   will be generated when the corresponding event state changes in either
**   direction (de-asserted to asserted or asserted to de-asserted). The
**   saHpiSensorEventEnablesSet() function also allows setting of general
**   sensor status - whether the sensor is completely disabled, or event
**   generation is completely disabled. 
**
** Parameters:
**   SessionId - [in] Handle to session context. 
**   ResourceId - [in] Resource ID of the addressed resource. 
**   SensorNum - [in] Sensor number for which the event enables are being
**      set. 
**   Enables - [in] Pointer to the structure containing the enabled status
**      for each event. 
**
** Return Value:
**   SA_OK is returned on successful completion; otherwise, an error code
**   is returned. 
**
** Remarks:
**   Disabling events means that events are disabled for all sessions, not
**   just the session referenced by the SessionId parameter.
**   saHpiSensorEventEnablesGet () will return the values which were last
**   set by saHpiSensorEventEnablesSet() for the "AssertEvents" and
**   "DeassertEvents" elements in the passed data structures. However, for
**   sensors hosted by any resource that has the
**   SAHPI_CAPABILITY_EVT_DEASSERTS flag set in its RPT entry, the passed
**   "AssertEvents" element on the saHpiSensorEventEnablesSet () function
**   is used for both assertion and de-assertion event enable flags. In
**   this case, this value will be returned in both the "AssertEvents" and
**   "DeassertEvents" elements on a subsequent saHpiSensorEventEnablesGet
**   () call.

**   The CtrlState parameter must be of the correct type for the specified

**   to include more characters in the text passed in the CtrlState
**   structure than will fit on one line; in this case, the control will
**   "wrap" to the next line (still clearing the trailing characters on the
**   last line written). Thus, there are two ways to write multiple lines

**   than will fit on one line. The caller should not assume any "cursor
**   positioning" characters are available to use, but rather should always
**   write full lines and allow "wrapping" to occur. When calling
**   saHpiControlStateSet() for a text control, the caller may set the line
**   number to SAHPI_TLN_ALL_LINES; in this case, the entire control will
**   be cleared, and the data will be written starting on line 0. (This is
**   different from simply writing at line 0, which only alters the lines
**   written to.) This feature may be used to clear the entire control,
**   which can be accomplished by setting: CtrlState->StateUnion.Text.Line
**   = SAHPI_TLN_ALL_LINES; CtrlState->StateUnion.Text.Text.DataLength = 0;

**
** Remarks:
**   Before calling saHpiEntityInventoryDataRead() the caller should
**   allocate a sufficiently large buffer to hold the data, and pass the
**   size of the buffer in the "BufferSize" parameter. The

**   will not be invoked. Once the auto-insertion process begins, the user
**   software will not be allowed to take control of the insertion process;
**   hence, the timeout should be set appropriately to allow for this
**   condition. Note that the timeout period begins when the hot swap event

**
** Parameters:
**   SessionId - [in] Handle to session context. 
**   Timeout - [in] The number of nanoseconds to wait before autonomous

**
** Name: saHpiAutoExtractTimeoutSet
**
** Description:
**   This function allows the caller to configure a timeout for how long to
**   wait before the default auto-extraction policy is invoked. This
**   function accepts a parameter instructing the implementation to impose
**   a delay before a resource will perform its default hot swap policy for
**   auto-extraction. The parameter may be set to SAHPI_TIMEOUT_IMMEDIATE
**   to direct the resource to proceed immediately to auto-extraction, or
**   to SAHPI_TIMEOUT_BLOCK to prevent auto-extraction from ever occurring
**   on a resource. If the parameter is set to another value, then it
**   defines the number of nanoseconds between the time a hot swap event
**   with HotSwapState = SAHPI_HS_STATE_EXTRACTION_PENDING is generated,
**   and the time that the auto- extraction policy will be invoked for the
**   resource. If, during this time period, a saHpiHotSwapControlRequest()
**   function is processed, the timer will be stopped, and the
**   auto-extraction policy will not be invoked. Once the auto-extraction
**   process begins, the user software will not be allowed to take control
**   of the extraction process; hence, the timeout should be set
**   appropriately to allow for this condition. Note that the timeout
**   period begins when the hot swap event with HotSwapState =
**   SAHPI_HS_STATE_EXTRACTION_PENDING is initially generated; not when it
**   is received by a caller with a saHpiEventGet() function call, or even
**   when it is placed in a session event queue. The auto-extraction policy
**   is set at the resource level and is only supported by resources
**   supporting the "Managed Hot Swap" capability. After discovering that a
**   newly inserted resource supports "Managed Hot Swap," middleware or
**   other user software may use this function to change the default
**   auto-extraction policy for that resource. If a resource supports the
**   simplified hot-swap model, setting this timer has no effect since the
**   resource will transition directly to "Not Present" state on an

** Description:
**   This function directs the resource to perform the specified reset type

**   entities, this function addresses the entity that is identified in the
**   RPT entry for the resource. Entities may be reset for a variety of
**   reasons. A misbehaving entity may be reset to bring it to a known
**   state. In these cases, either a warm reset or a cold reset may be
**   performed. A warm reset preserves entity state, whereas a cold reset
**   does not. Both of these reset types are pulsed asserted and then
**   de-asserted by the HPI implementation. This allows the HPI
**   implementation to hold the reset asserted for the appropriate length
**   of time, as needed by each entity. saHpiResourceResetStateSet() can
**   also be used for insertion and extraction scenarios. A typical
**   resource supporting hot swap will have to ability to control local
**   reset within the FRU. During insertion, a resource can be instructed
**   to assert reset, while the FRU powers on. During extraction a resource
**   can be requested to assert reset before the FRU is powered off. This
**   function allows the caller to set the reset state of the specified
**   FRU. SAHPI_RESET_ASSERT is used to hold the resource in reset; the FRU
**   is brought out of the reset state by using either SAHPI_COLD_RESET or
**   SAHPI_WARM_RESET. 
**
** Parameters:
**   SessionId - [in] Handle to session context. 
**   ResourceId - [in] Resource ID of the addressed resource. 
**   ResetAction - [in] Type of reset to perform on the entity. Valid reset
**      actions are:  SAHPI_COLD_RESET: Perform a 'Cold Reset' on the entity
**      (pulse), leaving reset de-asserted  SAHPI_WARM_RESET: Perform a 'Warm
**      Reset' on the entity (pulse), leaving reset de-asserted 
**      SAHPI_RESET_ASSERT: Put the entity into reset state and hold reset
**      asserted, e.g., for hot swap insertion/extraction purposes 
**
** Return Value:
**   SA_OK is returned if the resource has reset control, and the requested
**   reset action has succeeded; otherwise, an error code is returned.
**   SA_ERR_HPI_INVALID_CMD is returned if the resource has no reset
**   control, or if the requested reset action is not supported by the
**   resource. 
**
** Remarks:
**   Some resources may not support reset, or may only support a subset of
**   the defined reset action types. Also, on some resources, cold and warm
