* Most PPC hardware doesn't assign fixed addresses to hardware, which is

* much more leeway in building PPC systems. Unfortunately, because

/* DISPLAY OWNERSHIP
*
* So, who owns the physical display and is allowed to write to it?
*
* In MS NT, upon boot HAL owns the display. Somewhere in the boot
* sequence (haven't figured out exactly where or by who), some
* component calls HalAcquireDisplayOwnership. From that moment on,
* the display is owned by that component and is switched to graphics
* mode. The display is not supposed to return to text mode, except
* in case of a bug check. The bug check will call HalDisplayString
* to output a string to the text screen. HAL will notice that it
* currently doesn't own the display and will re-take ownership, by
* calling the callback function passed to HalAcquireDisplayOwnership.
* After the bugcheck, execution is halted. So, under NT, the only
* possible sequence of display modes is text mode -> graphics mode ->
* text mode (the latter hopefully happening very infrequently).
*
* Things are a little bit different in the current state of ReactOS.
* We want to have a functional interactive text mode. We should be
* able to switch from text mode to graphics mode when a GUI app is
* started and switch back to text mode when it's finished. Then, when
* another GUI app is started, another switch to and from graphics mode
* is possible. Also, when the system bugchecks in graphics mode we want
* to switch back to text mode to show the registers and stack trace.
* Last but not least, HalDisplayString is used a lot more in ReactOS,
* e.g. to print debug messages when the /DEBUGPORT=SCREEN boot option
* is present.
* 3 Components are involved in ReactOS: HAL, BLUE.SYS and VIDEOPRT.SYS.
* As in NT, on boot HAL owns the display. When entering the text mode
* command interpreter, BLUE.SYS kicks in. It will write directly to the
* screen, more or less behind HALs back.
* When a GUI app is started, WIN32K.SYS will open the DISPLAY device.
* This open call will end up in VIDEOPRT.SYS. That component will then
* take ownership of the display by calling HalAcquireDisplayOwnership.
* When the GUI app terminates (WIN32K.SYS will close the DISPLAY device),
* we want to give ownership of the display back to HAL. Using the
* standard exported HAL functions, that's a bit of a problem, because
* there is no function defined to do that. In NT, this is handled by
* HalDisplayString, but that solution isn't satisfactory in ReactOS,
* because HalDisplayString is (in some cases) also used to output debug
* messages. If we do it the NT way, the first debug message output while
* in graphics mode would switch the display back to text mode.
* So, instead, if HalDisplayString detects that HAL doesn't have ownership
* of the display, it doesn't do anything.
* To return ownership to HAL, a new function is exported,
* HalReleaseDisplayOwnership. This function is called by the DISPLAY
* device Close routine in VIDEOPRT.SYS. It is also called at the beginning
* of a bug check, so HalDisplayString is activated again.
* Now, while the display is in graphics mode (not owned by HAL), BLUE.SYS
* should also refrain from writing to the screen buffer. The text mode
* screen buffer might overlap the graphics mode screen buffer, so changing
* something in the text mode buffer might mess up the graphics screen. To
* allow BLUE.SYS to detect if HAL owns the display, another new function is
* exported, HalQueryDisplayOwnership. BLUE.SYS will call this function to
* check if it's allowed to touch the text mode buffer.
*
* In an ideal world, when HAL takes ownership of the display, it should set
* up the CRT using real-mode (actually V86 mode, but who cares) INT 0x10
* calls. Unfortunately, this will require HAL to setup a real-mode interrupt
* table etc. So, we chickened out of that by having the loader set up the
* display before switching to protected mode. If HAL is given back ownership
* after a GUI app terminates, the INT 0x10 calls are made by VIDEOPRT.SYS,
* since there is already support for them via the VideoPortInt10 routine.

* Header: remcom.c,v 1.34 91/03/09 12:29:49 glenne Exp $
*
* Module name: remcom.c $
* Revision: 1.34 $
* Date: 91/03/09 12:29:49 $
* Contributor: Lake Stevens Instrument Division$
*
* Description: low level support for gdb debugger. $
*
* Considerations: only works on target hardware $
*
* Written by: Glenn Engel $
* ModuleState: Experimental $
*
* NOTES: See Below $
*
* Modified for 386 by Jim Kingdon, Cygnus Support.
* Modified for ReactOS by Casper S. Hornstrup <chorns@users.sourceforge.net>
* Modified heavily for PowerPC ReactOS by arty
*
* To enable debugger support, two things need to happen. One, setting
* up a routine so that it is in the exception path, is necessary in order
* to allow any breakpoints or error conditions to be properly intercepted
* and reported to gdb.
* Two, a breakpoint needs to be generated to begin communication.
ER*
* Because gdb will sometimes write to the stack area to execute function
* calls, this program cannot rely on using the supervisor stack so it
* uses it's own stack area.
*
*************
*
* The following gdb commands are supported:
*
* command function Return value
*
* g return the value of the CPU Registers hex data or ENN
* G set the value of the CPU Registers OK or ENN
*
* mAA..AA,LLLL Read LLLL bytes at address AA..AA hex data or ENN
* MAA..AA,LLLL: Write LLLL bytes at address AA.AA OK or ENN
*
* c Resume at current address SNN ( signal NN)
* cAA..AA Continue at address AA..AA SNN
*
* s Step one instruction SNN
* sAA..AA Step one instruction from AA..AA SNN
*
* k kill
*
* ? What was the last sigval ? SNN (signal NN)
*
* All commands and responses are sent with a packet which includes a
* Checksum. A packet consists of
*
* $<packet info>#<Checksum>.
*
* where
* <packet info> :: <characters representing the command or response>
* <Checksum> :: < two hex digits computed as modulo 256 sum of <packetinfo>>
*
* When a packet is received, it is first acknowledged with either '+' or '-'.
* '+' indicates a successful transfer. '-' indicates a failed transfer.
*
* Example:
*
* Host: Reply:
* $m0,10#2a +$00010203040506070809101112131415#42
