-                 INT10  X86 Real Mode executor
-                 =============================
-
-		         PRELIMINARY
-
-INT10 is  a XFree86  module for soft-booting  and executing  real mode
-int10 BIOS calls. The BIOS call code is largely untested, yet.
-
-1. Usage
-========
-
-To   use   the   int10   module   in  a   driver   the   header   file
-xfree86/os-support/int10/xf86int10.h must be included.
-
- a. Initialization
- -----------------
-
-The int10-executer gets initialized by calling:
-
-   xf86Int10InfoPtr xf86InitInt10(int entityIndex);
-
-The  function  will soft-boot  any  non-primary  device  and return  a
-pointer  to a  xf86Int10InfoRec on  success. If  anything fails  or if
-int10 execution  is disabled by an  option in the  device section NULL
-will  be returned.   The driver  should store  this pointer  for later
-calls to other int10 module functions.
-
- b. Memory allocation
- --------------------
-
-To allocate memory in the real mode execution environment
-    
-   void * xf86Int10AllocPages(xf86Int10InfoPtr pInt,int num, int *off);
-
-can  be called.  It  allocates num  consecutive  pagesize chunks.   It
-returns the address of the allocated area. off is set to its offset in
-the real mode memory space.
-
-  void xf86Int10FreePages(xf86Int10InfoPtr pInt, void *pbase, int num);
-
-Is used to free num pages beginning at pbase.
-
- c. Doing int10 BIOS calls
- -------------------------
-
-The BIOS call is executed by calling:
-   
-   void xf86ExecX86int10(xf86Int10InfoPtr pInt);
-
-The number  of the interrupt (normally  10) and the  initial values of
-the ax, bx, cx, dx, si, di  and es x86-CPU registers can be set in the
-xf86Int10InfoRec  passed to  the function.   On return  this structure
-contains the  exit values  of the registers  listed above and  the CPU
-flag register.
-
- d. De-initializing
- -----------------
-
-If no further int10 calls are required for a certain chipset
-the driver should call:
-
-  void xf86FreeInt10(xf86Int10InfoPtr pInt);
-
-to free the memory allocated for real mode int10 calls.
-
-
-2. Porting issues
-=================
-
-The int10 real mode executor is  designed to run on top of various x86
-CPU emulators as well as in vm86  mode of a real x86 CPU. If used with
-a CPU  emulator the emulator and  CPU specific interfaces  can be held
-separate thus  requiring minimal efforts  to port the int10  module to
-new  platforms.   Currently  an  interface  to the  x86emu  real  mode
-emulator is  provided.  Since  details of setting  up and  running the
-vm86  mode   is  platform   dependent  both  the   platform  dependent
-environment and the emulation layer  have to be ported. Several helper
-functions are provided for that.
-
-A CPU emulator should meet certain requirements to be usable
-for the INT10 executor:
-
-1. It must trap  calls to intXX instructions and  pass execution to an
-   external  function  which  is   allowed  to  modify  CPU  registers
-   including  the instruction  pointer  (IP) before  returning to  the
-   emulator for  continuing execution.  When the external  function is
-   called the  IP must point to  the instruction past  the intXX call.
-
-2. The  emulator should  use externally  provided functions  to handle
-   PIO.
-
-3.  The emulator  should be able to use  externally provided functions
- to access memory  from the real mode memory  environment.  Note, that
- the  vm86  mode  usually  requires  one hunk  of  consecutive  memory
- starting at address  0 in the process virtual  memory space.  Thus if
- this mode is to be used, the OS environment has to be able to provide
- that, ie. it must be able to remap the processes virtual memory space
- onto itself.  If the  emulator is able  to handle memory  access thru
- externally  provided functions the  real mode  process memory  can be
- located anywhere  in the processes  virtual memory. It does  not even
- have to be consecutive.
-
-4. The executor should terminate on encountering a 'hlt' instruction.
-
-
-Functions to implement:
-
-To simplify development  the code has been split  into a general setup
-part and an emulator specific one. A generic setup code is provided in
-generic.c.  It  should be  usable  with  any  emulator satisfying  the
-conditions mentioned  above. Therefore the following  section on int10
-setup may be skipped when porting int10 to new emulator.
-
-If the  vm86() is to be used  no memory access functions  can be used.
-Therefore the layout of the real mode memory image has to meet certain
-requirements. Therefore  when porting to  other platforms a  new setup
-code may  have to  be designed, too.  The following section  will give
-guidelines how  this may be  done. A sample implementation  using SysV
-IPC to  map the  appropriate real  mode memory image  to address  0 in
-virtual  address  space  just  prior  to execution  may  be  found  in
-xfree86/os-support/linux/int10/linux.c.
-
-On  non-PC like  platforms emulation  of certain  PC features  such as
-initialization of  BIOS int vectors, sys_BIOS constants  or PCI config
-method 1 can be turned on by defining _PC.
-
-I. Setup Code
--------------
-
-This sets  up the real mode  memory image, calls the  emulator to POST
-the chipset if required and  maintains memory allocations in real mode
-address space.
-
-1. xf86Int10InfoPtr xf86InitInt10(int entityIndex);
-
-This  function should  first find  the screen  assigned to  the entity
-carrying entitiyIndex and then call
-
-       Bool int10skip(ScrnInfoPtr pScrn)
-
-to find out if the user  has requested not to initialize int10.  If so
-xf86InitInt10()  should  return  NULL. Otherwise  an  xf86Int10InfoRec
-should be allocated.  This structure contains the following fields:
-
-    a. int entityIndex   - index of the entity whose BIOS is to be 
-                           executed.
-    b. int scrnIndex     - index of the screen assigned the entity.
-    c. pointer cpuRegs   - pointer to a emulator/vm86-mode private 
-                           structure.  May hold cpu register values 
-                           for the emulator.
-    d. CARD16 BIOSseg    - Video BIOS segment address.
-    e. pointer private   - pointer to a os specific data structure.
-    f. struct _int10Mem* - pointer to a structure to hold the memory
-                           access functions for use by an emulator.
-    g. int num           - number of the int to be called.
-    h. int ax..es,flags  - CPU register values to pass to int-call.
-
-The Init  function should initialize  a-f. To initialize  the emulator
-specific execute environment the function
-
-     Bool xf86Int10ExecSetup(xf86Int10InfoPtr pInt)
-
-should be called. If this function returns FALSE any already allocated
-memory should be freed and xf86Int10Init(0 should exit returning NULL.
-
-If the  platform has  a PC  like system BIOS  it may  be copied  to or
-mapped into memory  locations SYS_BIOS to SYS_SIZE-1 of  the real mode
-memory environment of this process. Otherwise the helper function: 
-
-int setup_system_bios(CARD32 base_addr); 
-
-may be  called to set  up a rudimentary  system BIOS sufficient  to be
-used to  boot video BIOSes.   base_addr specifies the  virtual address
-corresponding to SYS_BIOS in the  real mode environment.  If a PC-like
-int vector and BIOS data area is available it should be copied to 0 to
-LOW_PAGE_SIZE of the entities real mode environment.  In this case the
-video interrupt  related entries should  be reset for  all non-primary
-cards by calling:
-
-void reset_int_vect(xf86Int10InfoPtr pInt); To initialize the
-
-correct video BIOS  entry points the BIOS must  be warm-booted.  If no
-PC-like int vector is available one can be set up by calling 
-
-void setup_int_vect(xf86Int10InfoPtr pInt); 
-
-In this  case the  video BIOS  has to be  warm-booted always.   If the
-video BIOS  for this entity has  been installed during boot  it may be
-mapped (or  copied) directly to the  correct address in  the real mode
-memory environment.  Otherwise
-
-int mapPciRom(xf86Int10InfoPtr pInt, unsigned char * address); 
-
-should  be called  to copy  the BIOS  image from  PCI  ROM.  'address'
-specifies the address this image should be copied to. Sufficient space
-to  hold an entire  BIOS image  should be  allocated prior  to calling
-mapPciRom(). This function  will return the size of  the BIOS image in
-bytes  if  it   was  able  to  successfully  copy   the  image  and  0
-otherwise. To create a well defined point to exit the softbooter
-
-void set_return_trap(xf86Int10Ptr pInt); 
-
-may be called.  It sets up a 'hlt' instruction  in the emulator memory
-just above the BIOS variable area. Before entering real mode execution
-this address will be pushed onto  the return stack.  If the BIOS needs
-to be  warm-booted this should be done  before leaving xf86InitInt10()
-by setting num in the xf86Int10InfoRec to 0xe6 and calling
-
-void xf86ExecX86int10(xf86Int10IfoPtr pInt); 
-
-The  implementation of this  function will  be discussed  below.  This
-function  should be  wrapped  by calls  to void  LockLegacyVGA(screen,
-legacyVGAPtr vga); and void UnlockLegacyVGA(screen, legacyVGAPtr vga);
-The struct  vga is  used to hold  the state  of the legacy  VGA access
-registers  if  a legacy  VGA  device  exists.  xf86InitInt10()  should
-return a pointer to the xf86Int10InfoRec allocated.
-
-2. Bool MapCurrentInt10(xf86Int10InfoPtr pInt);
-
-In case  a platform specific  mapping has to  be performed to  map the
-memory allocated for the real  mode memory environment into a specific
-location prior to executing the x86 real mode code a function
-
-        Bool MapCurrentInt10(xf86Int10InfoPtr pInt);
-
-has to  be provided. It will  be called by a  helper function whenever
-the active entity changes. If the  vm86 mode is used it is most likely
-that the 1MB real mode memory space located somewhere in the processes
-virtual memory  will have to be  remapped to address 0  of the virtual
-memory space.
-
-3.   void xf86FreeInt10(xf86Int10InfoPtr pInt);
-
-To free all memory allocated for video BIOS calls of a specific entity
-the function
-
-       void xf86FreeInt10(xf86Int10InfoPtr pInt);
-
-should  be  provided.  If  the  entity  to  be  freed  was  mapped  by
-MapCurrentInt10() this mapping needs to be undone also.
-
-4. 
-   void * xf86Int10AllocPages(xf86Int10InfoPtr pInt,int num, int *off)
-   void xf86Int10FreePages(xf86Int10InfoPtr pInt, void *pbase, int num)
-
-xf86Int10AllocPages()  should  allocate  'num'  consecutive  page-size
-chunks of memory. In real mode memory space this range needs to occupy
-consecutive addresses,  too. The function  must return the  address of
-this memory.  The offset in real  mode memory needs to  be returned in
-'off'. If  no block of 'num'  pages are available  the function should
-return NULL.
-
-xf86Int10FreePages() will  free the  'num' pages starting  at 'pbase'.
-'num'  is  equal  to  the  number  of  pages  allocated  by  a  single
-xf86Int10AllocatePages()  call. 'pbase'  is the  address of  the range
-previously returned by xf86Int10AllocatePages().
-
-II. Emulator specific functions
--------------------------------
-
-1. Bool xf86Int10ExecSetup(xf86Int10InfoPtr pInt);
-
-This function will  be called from xf86InitInt10(). It  may be used to
-set  up   the  static  emulator   specific  part  of  the   real  mode
-environment. On success it should return TRUE.
-
-2. xf86ExecX86int10(xf86Int10InfoPtr pInt);
-
-This function  gets called  to execute  an int call.  It may  call the
-helper function:
-
-       void setup_int(xf86Int10InfoPrt pInt);
-
-to copy the register values  to the emulator specific locations and to
-set up the non-static real mode execution environment.  On return from
-setup_int()   'Int10Current'   holds   a   pointer  to   the   current
-xf86Int10InfoRec.
-
-It should start execution by calling 
-
-       Bool int_handler(xf86Int10InfoPtr pInt);
-
-and if this function returns TRUE it should call whatever necessary to
-continue execution until a  'hlt' instruction is encountered.  To copy
-the resulting register values back to the xf86Int10InfoRec structure
-
-     void finish_int(xf86Int10InfoPtr pInt);
-
-should be called. 
-
-Helper  functions are  provided to  aid the  implementation of  a vm86
-call:
-
-  Bool vm86_GP_fault(xf86Int10InfoPtr pInt);
-
-This  function  handles  instructions  which  cause  a  vm86  call  to
-trap.  PIO  access  is handled  by  the  in/out  calls as  defined  in
-compiler.h. Optionally the PIO  instructions can be logged by defining
-PRINT_PORT in xf86int10.h. This is meant for debugging purposes.
-
-Unknown  instructions  and   'hlt'  cause  vm86_GP_fault()  to  return
-FALSE. Otherwise TRUE is returned.
-
-Note: This  function is  currently based on  the Linux vm86  call.  It
-might have  to be modified  or even rewritten  for other OS.   So your
-milage may vary.
-
-Functions to dump memory, code, xf86 CPU register values and stack are
-also provided.  Take a  look at  helper.c To view  a memory  range the
-function
-
-    void dprint(unsigned long start, unsigned long size)
-
-is provided. The use should be self explanatory.
-
-Register  and memory  access functions  are provided  in helper_mem.c.
-The PIO register access functions  can trap access to PCI config space
-access register (config method 1) if _PC is not defined.
-
-A header  file 'defines.h' is required to  define OS/emulator specific
-ways  to access  memory and  xf86 CPU  registers: Defines  need  to be
-provided     for    memory     byte/work/long     read/write    access
-(MEM_RB(name,addr),MEM_RW(name,addr),MEM_RL(name,addr),
-MEM_WB(name,addr,val),MEM_WL(name,addr,val),MEM_WL(name,addr,val))   of
-the real mode memory environment. 'name' will contain a pointer to the
-current   xf86Int10InfoRec.  Currently   defines  are   available  for
-vm86-mode under  Linux and x86emu.  They may be activated  by defining
-_X86EMU or _VM86_LINUX respectively.
-
-Note: Emulators usually are not able to pass this pointer when calling
-memory  access functions.  In this  case a  global variable  should be
-defined  which can  hold this  pointer. This  variable can  be  set in
-MapCurrentInt10().  It also  must be  set in  xf86InitInt10()  if this
-function  calls the  memory  access functions  either  directly or  by
-calling  xf86ExecX86int10(pInt).   Defines   to  access  the  emulator
-specific   xf86   CPU    register   locations   are   also   required:
-X86_EAX,...,X86_EFLAGS  for  access  of  the full  32  bit  registers,
-X86_AX...X86_FLAGS   for  access   of   the  16   bit  registers   and
-XF86_AL,XF86_BL,XF86_CL,XF86_DL  to  access  the  lower  byte  of  the
-AX,BX,CX and DX register.

+    g. int num           - number of the int to be called.

+    h. int ax..es,flags  - CPU register values to pass to int-call.

+

+The Init  function should initialize  a-f. To initialize  the emulator

+specific execute environment the function

+

+     Bool xf86Int10ExecSetup(xf86Int10InfoPtr pInt)

+

+should be called. If this function returns FALSE any already allocated

+memory should be freed and xf86Int10Init(0 should exit returning NULL.

+

+If the  platform has  a PC  like system BIOS  it may  be copied  to or

+mapped into memory  locations SYS_BIOS to SYS_SIZE-1 of  the real mode

+memory environment of this process. Otherwise the helper function: 

+

+int setup_system_bios(CARD32 base_addr); 

+

+may be  called to set  up a rudimentary  system BIOS sufficient  to be

+used to  boot video BIOSes.   base_addr specifies the  virtual address

+corresponding to SYS_BIOS in the  real mode environment.  If a PC-like

+int vector and BIOS data area is available it should be copied to 0 to

+LOW_PAGE_SIZE of the entities real mode environment.  In this case the

+video interrupt  related entries should  be reset for  all non-primary

+cards by calling:

+

+void reset_int_vect(xf86Int10InfoPtr pInt); To initialize the

+

+correct video BIOS  entry points the BIOS must  be warm-booted.  If no

+PC-like int vector is available one can be set up by calling 

+

+void setup_int_vect(xf86Int10InfoPtr pInt); 

+

+In this  case the  video BIOS  has to be  warm-booted always.   If the

+video BIOS  for this entity has  been installed during boot  it may be

+mapped (or  copied) directly to the  correct address in  the real mode

+memory environment.  Otherwise

+

+int mapPciRom(xf86Int10InfoPtr pInt, unsigned char * address); 

+

+should  be called  to copy  the BIOS  image from  PCI  ROM.  'address'

+specifies the address this image should be copied to. Sufficient space

+to  hold an entire  BIOS image  should be  allocated prior  to calling

+mapPciRom(). This function  will return the size of  the BIOS image in

+bytes  if  it   was  able  to  successfully  copy   the  image  and  0

+otherwise. To create a well defined point to exit the softbooter

+

+void set_return_trap(xf86Int10Ptr pInt); 

+

+may be called.  It sets up a 'hlt' instruction  in the emulator memory

+just above the BIOS variable area. Before entering real mode execution

+this address will be pushed onto  the return stack.  If the BIOS needs

+to be  warm-booted this should be done  before leaving xf86InitInt10()

+by setting num in the xf86Int10InfoRec to 0xe6 and calling

+

+void xf86ExecX86int10(xf86Int10IfoPtr pInt); 

+

+The  implementation of this  function will  be discussed  below.  This

+function  should be  wrapped  by calls  to void  LockLegacyVGA(screen,

+legacyVGAPtr vga); and void UnlockLegacyVGA(screen, legacyVGAPtr vga);

+The struct  vga is  used to hold  the state  of the legacy  VGA access

+registers  if  a legacy  VGA  device  exists.  xf86InitInt10()  should

+return a pointer to the xf86Int10InfoRec allocated.

+

+2. Bool MapCurrentInt10(xf86Int10InfoPtr pInt);

+

+In case  a platform specific  mapping has to  be performed to  map the

+memory allocated for the real  mode memory environment into a specific

+location prior to executing the x86 real mode code a function

+

+        Bool MapCurrentInt10(xf86Int10InfoPtr pInt);

+

+has to  be provided. It will  be called by a  helper function whenever

+the active entity changes. If the  vm86 mode is used it is most likely

+that the 1MB real mode memory space located somewhere in the processes

+virtual memory  will have to be  remapped to address 0  of the virtual

+memory space.

+

+3.   void xf86FreeInt10(xf86Int10InfoPtr pInt);

+

+To free all memory allocated for video BIOS calls of a specific entity

+the function

+

+       void xf86FreeInt10(xf86Int10InfoPtr pInt);

+

+should  be  provided.  If  the  entity  to  be  freed  was  mapped  by

+MapCurrentInt10() this mapping needs to be undone also.

+

+4. 

+   void * xf86Int10AllocPages(xf86Int10InfoPtr pInt,int num, int *off)

+   void xf86Int10FreePages(xf86Int10InfoPtr pInt, void *pbase, int num)

+

+xf86Int10AllocPages()  should  allocate  'num'  consecutive  page-size

+chunks of memory. In real mode memory space this range needs to occupy

+consecutive addresses,  too. The function  must return the  address of

+this memory.  The offset in real  mode memory needs to  be returned in

+'off'. If  no block of 'num'  pages are available  the function should

+return NULL.

+

+xf86Int10FreePages() will  free the  'num' pages starting  at 'pbase'.

+'num'  is  equal  to  the  number  of  pages  allocated  by  a  single

+xf86Int10AllocatePages()  call. 'pbase'  is the  address of  the range

+previously returned by xf86Int10AllocatePages().

+

+II. Emulator specific functions

+-------------------------------

+

+1. Bool xf86Int10ExecSetup(xf86Int10InfoPtr pInt);

+

+This function will  be called from xf86InitInt10(). It  may be used to

+set  up   the  static  emulator   specific  part  of  the   real  mode

+environment. On success it should return TRUE.

+

+2. xf86ExecX86int10(xf86Int10InfoPtr pInt);

+

+This function  gets called  to execute  an int call.  It may  call the

+helper function:

+

+       void setup_int(xf86Int10InfoPrt pInt);

+

+to copy the register values  to the emulator specific locations and to

+set up the non-static real mode execution environment.  On return from

+setup_int()   'Int10Current'   holds   a   pointer  to   the   current

+xf86Int10InfoRec.

+

+It should start execution by calling 

+

+       Bool int_handler(xf86Int10InfoPtr pInt);

+

+and if this function returns TRUE it should call whatever necessary to

+continue execution until a  'hlt' instruction is encountered.  To copy

+the resulting register values back to the xf86Int10InfoRec structure

+

+     void finish_int(xf86Int10InfoPtr pInt);

+

+should be called. 

+

+Helper  functions are  provided to  aid the  implementation of  a vm86

+call:

+

+  Bool vm86_GP_fault(xf86Int10InfoPtr pInt);

+

+This  function  handles  instructions  which  cause  a  vm86  call  to

+trap.  PIO  access  is handled  by  the  in/out  calls as  defined  in

+compiler.h. Optionally the PIO  instructions can be logged by defining

+PRINT_PORT in xf86int10.h. This is meant for debugging purposes.

+

+Unknown  instructions  and   'hlt'  cause  vm86_GP_fault()  to  return

+FALSE. Otherwise TRUE is returned.

+

+Note: This  function is  currently based on  the Linux vm86  call.  It

+might have  to be modified  or even rewritten  for other OS.   So your

+milage may vary.

+

+Functions to dump memory, code, xf86 CPU register values and stack are

+also provided.  Take a  look at  helper.c To view  a memory  range the

+function

+

+    void dprint(unsigned long start, unsigned long size)

+

+is provided. The use should be self explanatory.

+

+Register  and memory  access functions  are provided  in helper_mem.c.

+The PIO register access functions  can trap access to PCI config space

+access register (config method 1) if _PC is not defined.

+

+A header  file 'defines.h' is required to  define OS/emulator specific

+ways  to access  memory and  xf86 CPU  registers: Defines  need  to be

+provided     for    memory     byte/work/long     read/write    access

+(MEM_RB(name,addr),MEM_RW(name,addr),MEM_RL(name,addr),

+MEM_WB(name,addr,val),MEM_WL(name,addr,val),MEM_WL(name,addr,val))   of

+the real mode memory environment. 'name' will contain a pointer to the

+current   xf86Int10InfoRec.  Currently   defines  are   available  for

+vm86-mode under  Linux and x86emu.  They may be activated  by defining

+_X86EMU or _VM86_LINUX respectively.

+

+Note: Emulators usually are not able to pass this pointer when calling

+memory  access functions.  In this  case a  global variable  should be

+defined  which can  hold this  pointer. This  variable can  be  set in

+MapCurrentInt10().  It also  must be  set in  xf86InitInt10()  if this

+function  calls the  memory  access functions  either  directly or  by

+calling  xf86ExecX86int10(pInt).   Defines   to  access  the  emulator

+specific   xf86   CPU    register   locations   are   also   required:

+X86_EAX,...,X86_EFLAGS  for  access  of  the full  32  bit  registers,

+X86_AX...X86_FLAGS   for  access   of   the  16   bit  registers   and

+XF86_AL,XF86_BL,XF86_CL,XF86_DL  to  access  the  lower  byte  of  the

+AX,BX,CX and DX register.

+
