-/* 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.

-/**
- * @page DMA Implementation Notes
- *
- * Concepts:
- *
- * - Map register
- *
- * Abstract encapsulation of physically contiguous buffer that resides
- * in memory accessible by both the DMA device / controller and the system.
- * The map registers are allocated and distributed on demand and are
- * scarce resource.
- *
- * The actual use of map registers is to allow transfers from/to buffer
- * located in physical memory at address inaccessible by the DMA device /
- * controller directly. For such transfers the map register buffers
- * are used as intermediate data storage.
- *
- * - Master adapter
- *
- * A container for map registers (typically corresponding to one physical
- * bus connection type). There can be master adapters for 24-bit address
- * ranges, 32-bit address ranges, etc. Every time a new DMA adapter is
- * created it's associated with a corresponding master adapter that
- * is used for any map register allocation requests.
- *
- * - Bus-master / Slave DMA
- *
- * Slave DMA is term used for DMA transfers done by the system (E)ISA
- * controller as opposed to transfers mastered by the device itself
- * (hence the name).
- *
- * For slave DMA special care is taken to actually access the system
- * controller and handle the transfers. The relevant code is in
- * HalpDmaInitializeEisaAdapter, HalReadDmaCounter, IoFlushAdapterBuffers
- * and IoMapTransfer.
- *
- * Implementation:
- *
- * - Allocation of map registers
- *
- * Initial set of map registers is allocated on the system start to
- * ensure that low memory won't get filled up later. Additional map
- * registers are allocated as needed by HalpGrowMapBuffers. This
- * routine is called on two places:
- *
- * - HalGetAdapter, since we're at PASSIVE_LEVEL and it's known that
- * more map registers will probably be needed.
- * - IoAllocateAdapterChannel (indirectly using HalpGrowMapBufferWorker
- * since we're at DISPATCH_LEVEL and call HalpGrowMapBuffers directly)
- * when no more map registers are free.
- *
- * Note that even if no more map registers can be allocated it's not
- * the end of the world. The adapters waiting for free map registers
- * are queued in the master adapter's queue and once one driver hands
- * back it's map registers (using IoFreeMapRegisters or indirectly using
- * the execution routine callback in IoAllocateAdapterChannel) the
- * queue gets processed and the map registers are reassigned.
