* EQUATES FOR REQUIRED DEVICES
*
* Device ID formulation note:
*
* The high bit of the device ID is reserved for future use.
* Microsoft reserves the device ID's 0-1FFh for standard devices. If
* an OEM VxD is a replacement for a standard VxD, then it must use the
* standard VxD ID.
*
* OEMS WHO WANT A VXD DEVICE ID ASSIGNED TO THEM,
* PLEASE CONTACT MICROSOFT PRODUCT SUPPORT. ID's are only required for
* devices which provide services, V86 API's or PM API's. Also, calling
* services or API's by VxD name is now supported in version 4.0, so an
* ID may not be necessary as long as a unique 8 character name is used.

; The following macros are used in defining the routines
; in a VxD which are going to be registered with VMM as callable entry
; points. Once registered, the entry points can be called by any other
; devices via the "VxDCall" macro, defined below. In the comments below,
; replace "VxD" with the appropriate device name.
;
;*******
; In the VxD.INC file, put the following lines, replacing <function_name>
; with an appropriate name describing the function of the routine.
;
; Begin_Service_Table VxD[,<segname>]
; VxD_Service <function_name>[,<local segname>]
; VxD_Service <function_name>[,<local segname>]
; . . .
; VxD_Service <function_name>[,<local segname>]
; End_Service_Table VxD[,<segname>]
;
; Note that <segname> is an optional argument and, if specified, the
; table is put in the segment defined by the macro "yyy_Data_Seg",
; where yyy=segname. Otherwise the segment is defined by the
; "VxD_Data_Seg" macro, defined below.
; Note that <local segname> is an optional argument and, if specified,
; the procedure's segment is defined by the macro "zzz_Code_Seg",
; where zzz=segname. Otherwise the segment is defined by the
; "VxD_Code_Seg" macro, defined below.
;
;*******
; One VxD module should have the following in order to define the entry points:
;Create_VxD_Service_Table = 1 ; Only in module where table is
; INCLUDE VxD.INC ; Include the table definition
;
;*******
; All modules that want to call the services defined in the table should include
; VxD.INC, but not define the label "Create_VxD_Service_Table". This
; will define the service names to be used with the VxDCall macro.

/***ET+ PD - Pager Descriptor
*
* A PD describes a set of routines to call to bring a page into
* the system or to get it out. Each committed page in the system
* has an associated PD, a handle to which is stored in the page's
* VP.
*
* For any field that is 0, the pager will not be notified
* when that action takes place.
*
* For the purpose of pagers, a page can be in one of the two states
* describing its current contents:
*
* clean - page has not been written to since its last page out
* dirty - page has been written to since its last page out
*
* A page also is in one of two persistent states:
*
* virgin - page has never been written to since it was committed
* tainted - page has been written to since it was committed
*
* Note that a tainted page may be either dirty or clean, but a
* virgin page is by definition clean.
*
* Examples of PDs:
*
* For 32-bit EXE code or read-only data:
*
* pd_virginin = routine to load page from an exe file
* pd_taintedin = 0
* pd_cleanout = 0
* pd_dirtyout = 0
* pd_virginfree = 0
* pd_taintedfree = 0
* pd_dirty = 0
* pd_type = PD_PAGERONLY
*
* For 32-bit EXE writeable data:
*
* pd_virginin = routine to load page from an exe file
* pd_taintedin = routine to load page from swap file
* pd_cleanout = 0
* pd_dirtyout = routine to write a page out to the swap file
* pd_virginfree = 0
* pd_taintedfree = routine to free page from the swap file
* pd_dirty = routine to free page from the swap file
* pd_type = PD_SWAPPER
*
* For zero-initialized swappable data:
*
* pd_virginin = routine to zero-fill a page
* pd_taintedin = routine to load page from swap file
* pd_cleanout = 0
* pd_dirtyout = routine to write a page out to the swap file
* pd_virginfree = 0
* pd_taintedfree = routine to free page from the swap file
* pd_dirty = routine to free page from the swap file
* pd_type = PD_SWAPPER

* free to modify the contents of this dword
* DURING the page in or out, but not afterwards.
*
* ppage - pointer to page going in or out (a ring 0 alias
* to the physical page). The pager should use this
* address to access the contents of the page.
*
* faultpage - faulting linear page number for page-ins, -1 for
* page-outs. This address should not be accessed
* by the pager. It is provided for information
* only. Note that a single page can be mapped at

* the pager's pd_dirty routine will be called once for each

* PD_PAGERONLY - pages controlled by this pager will never
* be paged out to the swap file
*
* In addition, the following value may be or'ed in to the pd_type field:
*
* PD_NESTEXEC - must be specified if either the pd_cleanout or pd_dirtyout

;******************************************************************************
; BeginProc is a macro for defining entry points to routines in VMM and in the
; VxDs. It correctly defines the procedure name for VxD services, DWORD
; aligns the procedure, takes care of public declaration and does some
; calling verification for debug versions of the software. EndProc is a
; macro which defines the end of the procedure.
;
; Valid parameters to the BeginProc macro are:
; PUBLIC ; Used outside this module (default)
; LOCAL ; Local to this module
; HIGH_FREQ ; DWORD align procedure
; SERVICE ; Routine is called via VxDCall
; ASYNC_SERVICE ; Same as "SERVICE" plus routine can
; ; be called under interrupt.
; HOOK_PROC ; Proc is a handler installed with
; ; with a call to Hook_xxx_Fault
; ; or Hook_Device_Service. The
; ; following parameter must be
; ; the label of a DWORD location
; ; which will hold the ptr to next
; ; hook proc. e.g.
;
; ;BeginProc foo, SERVICE, HOOK_PROC, foo_next_ptr
;
; NO_LOG ; Disable Queue_Out call logging
; NO_PROFILE ; Disable DynaLink profile counts
; NO_TEST_CLD ; Disable direction flag check
;
; TEST_BLOCK ; Trap if in NOBLOCK state
; ; (default if in pageable code seg)
; TEST_REENTER ; Trap if Get_VMM_Reenter_Count != 0
; ; (default for non-async services)
; NEVER_REENTER ; Trap if VMM has been reentered
; NOT_SWAPPING ; Trap if this thread is swapping
;
; NO_PROLOG ; Disable all prolog tests
;
; ESP ; Use ESP instead of EBP for stack
; ; frame base
; PCALL ; pascal calling convention
; SCALL ; stdcall calling convention
; FASTCALL ; stdcall, but first 2 parameters are passed in ECX & EDX
; CCALL ; "C" calling convention
; ICALL ; default calling convention
; W32SVC ; Win32 service
;
; segment type ; Place function in specified segment
;
; The NO_PROFILE flag merely suppresses incrementing the profile count.
; The DWORD of profiling information will still be emitted to appease
; the debugger. If you want to increment the profile count manually,
; use the IncProfileCount macro.
;
; TEST_REENTER and NEVER_REENTER differ in that the VMM reentry count
; returned by Get_VMM_Reenter_Count is artifically forced to zero by
; Begin_Reentrant_Execution, whereas the counter checked by NEVER_REENTER
; reflects the genuine count of VMM reentry.
;
; A segment type (such as LOCKED, PAGEABLE, STATIC, INIT, DEBUG_ONLY) can be
; provided, in which case the BeginProc and EndProc macros will
; automatically place the appropriate segment directives around the
; definition of the function.
;
; segment type ; Place function in specified segment
;
; After the routine header in which the routine entry conditions, exit
; conditions, side affects and functionality are specified, the BeginProc
; macro should be used to define the routine's entry point. It has up to
; four parameters as specified below. For example:
;
;BeginProc <Function_Name>,PUBLIC, HIGH_FREQ, SERVICE, ASYNC_SERVICE, ESP
;
; <code>
;
;EndProc <Function_Name>

;
; BeginProc handling takes place in the following phases:
;
; Phase 1: Parsing the arguments.
; Phase 2: Setting default flags.
; Phase 3: Combining the flags.
; Phase 4: Code emitted before the label
; Phase 5: Munge the name as exported to C/Pascal/whoever
; Phase 6: _Debug_Flags_Service prolog

; The Begin_Control_Dispatch macro is used for building a table for dispatching
; messages passed to the VxD_Control procedure. It is used with
; Control_Dispatch and End_Control_Dispatch. The only parameter is used to
; contruct the procedure label by adding "_Control" to the end (normally the
; device name is used i.e. VKD results in creating the procedure VKD_Control,
; this created procedure label must be included in Declare_Virtual_Device)
;
; An example of building a complete dispatch table:
;
; Begin_Control_Dispatch MyDevice
; Control_Dispatch Device_Init, MyDeviceInitProcedure
; Control_Dispatch Sys_VM_Init, MyDeviceSysInitProcedure
; Control_Dispatch Create_VM, MyDeviceCreateVMProcedure
; End_Control_Dispatch MyDevice
;
; (NOTE: Control_Dispatch can be used without Begin_Control_Dispatch, but
; then it is the programmer's responsibility for declaring a procedure
; in locked code (VxD_LOCKED_CODE_SEG) and returning Carry clear for
; any messages not processed. The advantage in using
; Begin_Control_Dispatch is when a large # of messages are processed by
; a device, because a jump table is built which will usually require
; less code space then the compares and jumps that are done when
; Control_Dispatch is used alone.
