; File: DockingMgr.a
;
; Contains: support for docking portable Macintoshes into desktop docking modules
;
; Written by: Steve Christensen
;
; Copyright: <09> 1992-1993 by Apple Computer, Inc. All rights reserved.
;
; This file is used in these builds: ROM
;
; Change History (most recent first):
;
; <SM8> 12/13/93 PN Roll in KAOs and Horror changes to support Malcom and AJ
; machines.
; <SM7> 9/2/93 KH Rolled in the Horror changes (finally)
; <SM7> 9/2/93 SKH My fixes are back in now...
; <SM6> 9/1/93 SKH Backed out my changes until I was certain they wouldn't break builds.
; <SM5> 9/1/93 SKH Rolled in Horror version of docking code (with dock cache control stuff)
; <SM4> 12/4/92 GD Added a forRomulator conditional so that we don't (re)initialize
; the SCC when debugging.
; <SM3> 11/20/92 SWC Rolled in the rest of the Horror changes. Changed INCLUDEs to
; use new filenames.
; <H26> 8/13/92 SWC Added a new selector call in SetupDockBases to do any last
; minute pre-boot initialization. This is provided as a means of
; allowing the config ROMs to patch up anything we might have
; forgotten.
; <H25> 8/11/92 SWC Exported DockInitSCC and fixed it to preserve its registers.
; <H24> 8/10/92 SWC Specifically check for (and handle) the <20>docking slot<6F> selector
; in DockingDispatch so handlers, etc., have a way of determining
; which slot they're in.
; <H23> 7/29/92 SWC Fixed a typo (ended up looking at the wrong thing).
; <H22> 7/27/92 SWC Block checking for eject until after we get to the Finder.
; <H21> 7/24/92 SWC Added a check if a bar was added during sleep that's not
; supposed to be added then, and if so, the next time we wake up,
; remove its handler, etc. (takes care of the case of trying to
; add it multiple times).
; <H20> 7/8/92 SWC Made some changes to GracefulShutdown to make it better at
; successfully shutting down. DockingFilter now prevents waking up
; if we'd have to run without the LCD display since we currently
; can't handle removing a monitor from the desktop.
; <H19> 7/1/92 SWC Reset internal [and external] SCCs in SetHardwareBases so we
; won't get spurious interrupts from the unused SCC when a bar
; with another SCC is connected during sleep.
; <H18> 6/29/92 HJR SWC/Fixed my fix to Dave Wong's external32bit code from <H14>.
; <H17> 6/29/92 SWC Added in code to allow us to do a graceful shutdown when the
; eject button is pressed on a docking station.
; <H16> 6/25/92 SWC Pulled out the save/restore A2 code in <H13> since that's all
; fixed now. TravelBarHandler now returns SWIM2 power status if a
; SWIM2 exists.
; <H15> 6/18/92 SWC As part of our continuing incestuous relationship with the Power
; Manager, clear the clamshellClosed flag in the <20>sleep denied<65>
; Notification Manager completion routine so we won't try to keep
; posting messages until the current one goes away. Added
; RegisterVideo to the wakeup installation so we'll have a hook to
; let the system know about the addition of a new video device. It
; currently does nothing.
; <H14> 6/15/92 ag Added code to set the external32bit flag in the gdflags of
; gdevice data structure based the information from the slot
; manager.
; <H13> 6/3/92 SWC Cleaned up some of my duplicated code. Temporarily save/restore
; A2 around calls to the docking handler because the DeskBar and
; Gemini docking handlers trash it (a bug to be fixed).
; <H12> 6/1/92 HJR Changed CheckConnectNiagra for our current implementation. Call
; InitDefGamma in vAddVideoDevice.
; <H11> 5/29/92 SWC Set up docking support for Dartanian. Added a routine to notify
; the user that they tried to attach a bar during sleep that's not
; supposed to be added during sleep.
; <H10> 5/20/92 SWC Now pass the CPU's clock speed to the docking handler so it can
; configure any of its hardware that cares.
; <H9> 5/8/92 SWC Added a new routine to call Alex Kazim's Comm Toolbox hack to
; resolve which serial ports are currently available. Abort wakeup
; docking handler installation if that kind of bar is not allowed
; to be added during sleep.
; <SM2> 10/22/92 CS Change some branch short instructions to branches.
; <1> 5/16/92 kc first checked in
; <H8> 4/22/92 SWC Changed DockingWakeup so that it will only add video if video is
; supported AND a monitor is connected, so we can handle the case
; of adding a bar to use the floppy disk and then remove it when
; we're done (with video it would be locked in until shutdown).
; Added a new routine (DockingSleepDenied) to put up a
; Notification Manager dialog to let the user know that they can't
; put the system to sleep when a bar won't allow it.
; <H7> 4/13/92 SWC Added a flag to show that a bar was added during sleep. Added a
; check for eject from a docking station. Did some code cleanup.
; <H6> 4/3/92 SWC Increased the overpatch padding size to 4K.
; <H5> 3/20/92 SWC Rolled in Dave Wong's new Slot Manager support, and fixed how
; the sleep and wakeup code works. Vectored some more routines.
; Increased the overpatch file size from 1K to 2K since it
; overflowed.
; <H4> 3/6/92 SWC Enable/disable docking slot interrupts depending on whether or
; not a bar is connected. Make the built-in docking handlers
; return the SCC ports available when no bar is connected.
; <H3> 3/3/92 SWC Moved the check for SCSI Disk Mode to SCSIDiskMode.a since
; that's now part of the build, and the logical place to put it.
; <H2> 2/17/92 SWC Load the bar's docking attributes into the Power Manager globals
; so we can decide if we want to sleep, power cycle, etc.
; <H1> 2/14/92 SWC First checked in.

; Routine: PrattDockingFilter
;
; Inputs: D0 - docking attributes returned by the bar
; A2 - pointer to Docking Manager's globals
;
; Outputs: D0 - filtered docking attributes
;
; Trashes: D1,D2,A0,A1
;
; Function: Filters the docking attributes so we can decide how to behave depending on what kind
; of system software support we have. The Display Manager is (currently) a disk thing,
; so we<77>ll patch this filter out on disk if the Display Manager is around, otherwise
; we don<6F>t allow sleeping if external video is enabled.
;
; Note: This filter differs from the <20>standard<72> filters in that we don<6F>t need to check
; for the case where the LCD screen isn<73>t useable (since all-in-one PowerBooks
; don<6F>t <20>dock<63> per se), and since Pratt is <20>040 based, the FPU doesn<73>t matter.
; (I believe that the FPU won<6F>t matter for the PowerPC case, either.)

; Function: Since the <20>bar<61> on Pratt-based CPUs is built-in, the Docking Handler would never be
