;	Initial checkin for stepper kernel support for PowerBooks
;	
;
;   Example step definition file
;
;   This file should be compiled with the pmsset program.  It will compile and check 
;   for errors.  Eventually when I finish it, it will push the step table into the kernel
;   and activate it on all processors.
;
;   This is for testing.  I assume that normally we will have something in the kernel to
;   define this stuff although this could be used to modify the defaults for special
;   user applications.
;
;   Step definitions 0 - 9 are required and should not change meaning.
;
;   pmsIdle is the power for the idle loop (including nap) and should be lowest. 
;       We step up when we have work to do and exit the loop.  There is no time limit here.
;
;   pmsNorm is still low power and is the first step out of idle.  Time limit here.
;
;   pmsNormHigh is the highest normal power and is where we assume we are after boot.
;
;   pmsBoost is the overdrive step and should have a time limit but can be unlimited.
;
;   pmsLow is the lowest power, no time limit.  Used to force low power, if needed.
;
;   pmsHigh is highest normal, no time limit.  Used to for highest non-overdrive power, if needed.
;
;   pmsPrepCng is Prepare for step table change
;
;   pmsPrepSleep is Prepare for sleep
;
;	pmsOverTemp is for when the processor has gotten too hot
;
;	pmsEnterNorm is used to transition back into the normal step program 
;
;   pmsParked transitions to a parked state.  There is no corresponding step table entry.  It is a fixed valid of 0xFFFFFFFF.
;
;
;   There can be up to 64 steps.
;
;   The down field is the step to transition to when power is to be dropped.  Normally this 
;       would be idle.  Currently the transition point is on entry to the idle loop.
;		A -1 specifies that the next step is parked.
;
;   The next field is the normal forward step.  The power could go down, up, or stay the same.
;       This is normally triggered by the expiration of the time limit.
;		A -1 specifies that the next step is parked.
;
;   The combination of HWSel and HWfun determine the actual power state.  When we transition
;       to a step, HWfun is called with HWSel as the parameter.  Nothing is called if HWfun
;       is 0, or if we are already in that state.  Note that there can be forced transitions
;       that will call HWfun (if it exists) regardless of the current state.
;
;   The limit field is the time before transition to the next step.  It is in units
;       of microseconds and can be from 100 to 3155760000000000 (one century).
;       Leaving the field blank or -1 defaults to a century.
;       A zero indicates that this is an immediate step with no wait
;
;   The TDelay field is only valid for a pmsDelay command and is used to hold off a step down for the time limit.
;       If the limit expires, then we step to TDelay.  A step up takes the next and an explicit down take the down.
;       The limit field must be specified and must be non-zero and not infinite.  Note that TDelay can not
;       transition to park.
;
;
;   The current implementation of the hardware selector for Powerbooks with Intrepid is as follows:
;
;       bits                        meaning
;
;       pmsCngXClk  0x80000000      Change external clock
;       pmsXClk     0x7F000000      External clock frequency
;       pmsCngCPU   0x00800000      Change CPU parameters
;       pmsSync     0x00400000      Make changes synchronously, i.e., spin until delay finished
;       pmsMustCmp  0x00200000      Delay must complete before next change
;       pmsCPU      0x001F0000      CPU frequency
;       pmsCngVolt  0x00008000      Change voltage
;       pmsVoltage  0x00007F00      Voltage
;       pmsPowerID  0x000000FF      Identify power state to HW
;
;		pmsDelay    0xFFFFFFFD		Delayed step, no processor or platform changes.  Timer expiration causes transition to pmsTDelay
;       pmsParkIt   0xFFFFFFFF      Special value to indicate that we are to park
;

;	Rule set for this table (per Keith Cox)
;		Operating at F=Full requires V=High
;		Transitioning between F=Qtr and F=Half requires V=High
;		Operating at F=Qtr, Half desirable for V=Low
;		All requests for V=High require a minimum 400s assertion
;		All table entry point require a minimum 400s delay before setting V=Low to guarantee V=High assertion time
;		Operation at F=Qtr requires AAck delay=2
;		Operation at F=Half, Full desirable for AAck delay=0
;		Idle times shorter than 500s should not cause a performance step down
