- [VIDEOPRT] Return the real PhysicalDeviceObject in Win32k callbacks.
- [WIN32SS:ENG] Pass PhysDeviceObject into the GraphicsDevice structure
and rename the destination field accordingly.
- [WIN32SS:NTUSER] Request hardware identifiers from device PDO and
fill DISPLAY_DEVICE's DeviceID field with the first identifier.
Now it's correctly passed to the usermode, and Desktop Propertes applet
can open the video adapter device properties.
Thanks to Hervé Poussineau for the help.

This reverts commit c243133b2c.
Without the revert, VirtualBox auto-resize doesn't work on first attempt,
but only on next ones.
However, according to documentation, we must only initialize device and
cache information when iModeNum = 0.
CORE-18189
Initialization of device mode list will be done later, just before switching to graphics mode.
If no graphic display is available, we will now fail when starting first GUI application in
co_IntGraphicsCheck(). Add a bugcheck here to prevent frozen screen.
- make it return a new allocated PDEVMODEW instead of a pointer into
existing PGRAPHICS_DEVICE (usefull when available display modes can
dynamically change: VirtualBox, RDP, ...)
- update all callers
This is done by creating the volatile key
\Registry\Machine\System\CurrentControlSet\Control\GraphicsDrivers\BaseVideo .
Also cache during first initialization of VIDEOPRT the state of the boot
options BASEVIDEO and NOVESA, so that they can be readily retrieved later
(for example, in VideoPortIsNoVesa()).
CORE-12149
VIDEOPRT:
=========
Improve interfacing with INBV, so as to detect when an external module
acquired INBV display ownership, and whether ownership is being released
later on. (This does NOT rely on hooking!)
For this purpose we improve the IntVideoPortResetDisplayParameters(Ex)
callback that gets registered with an InbvNotifyDisplayOwnershipLost()
call during initialization, and we add a monitoring thread.
The callback is called whenever an external module calls
InbvAcquireDisplayOwnership(), for example the bugcheck code or the KDBG
debugger in SCREEN mode. When this happens, a flag that tells the
monitoring thread to start monitoring INBV is set (ReactOS-specific),
and the display adapters get reset with HwResetHw() (as done on Windows).
Due to the fact that this INBV callback can be called at *ANY* IRQL, we
cannot use dispatcher synchronization mechanisms such as events to tell
the INBV monitoring thread to start its operations, so we need to rely
instead on a flag to be set. And, since INBV doesn't provide with any
proper callback/notification system either, we need to actively monitor
its state by pooling. To reduce the load on the system the monitoring
thread performs 1-second waits between each check for the flag set by
the INBV callback, and during checking the INBV ownership status.
When the INBV ownership is detected to be released by an external module,
the INBV callback is re-registered (this is *MANDATORY* since the
external module has called InbvNotifyDisplayOwnershipLost() with a
different callback parameter!), and then we callout to Win32k for
re-enabling the display.
This has the virtue of correctly resetting the display once the KDBG
debugger in SCREEN mode is being exited, and fixes CORE-12149 .
The following additional fixes were needed:
VIDEOPRT & WIN32K:
==================
Remove the registration with INBV that was previously done in a ReactOS-
specific hacked IRP_MJ_WRITE call; it is now done correctly during the
video device opening done by EngpRegisterGraphicsDevice() in the VIDEOPRT's
IRP_MJ_CREATE handler, as done on Windows.
WIN32K:
=======
- Stub the VideoPortCallout() support, for VIDEOPRT -> WIN32 callbacks.
This function gets registered with VIDEOPRT through an
IOCTL_VIDEO_INIT_WIN32K_CALLBACKS call in EngpRegisterGraphicsDevice().
- Only partially implement the 'VideoFindAdapterCallout' case, that just
re-enables the primary display by refreshing it (using the new function
UserRefreshDisplay()).
VIDEOPRT:
=========
- PVIDEO_WIN32K_CALLOUT is an NTAPI (stdcall) callback.
- In the IntVideoPortResetDisplayParameters(Ex) callback, reset all the
"resettable" adapters registered in the HwResetAdaptersList list.
We thus get rid of the global ResetDisplayParametersDeviceExtension.
- Make the IntVideoPortResetDisplayParameters(Ex) callback slightly more
robust (using SEH) against potential HwResetListEntry list corruption
or invalid DriverExtension->InitializationData.HwResetHw() that would
otherwise trigger a BSOD, and this would be disastrous since that
callback is precisely called when INBV is acquired, typically when the
BSOD code initializes the display for displaying its information...
Extras:
- Validate the IrpStack->MajorFunction in IntVideoPortDispatchDeviceControl()
and implement IRP_MJ_SHUTDOWN handling. Stub out the other IOCTLs that
are handled by VIDEOPRT only (and not by the miniports).
- VIDEOPRT doesn't require IRP_MJ_INTERNAL_DEVICE_CONTROL (unused).
- Implement IOCTL_VIDEO_PREPARE_FOR_EARECOVERY that just resets the
display to standard VGA 80x25 text mode.
This helps when e.g. changing the resolution on the Dell Latitude D531,
which reports that it supports large resolutions (e.g. 1920x1440x32 and
others larger than 1024x768x32) but fails to apply these.
This usually happens because PDEVOBJ_pSurface(), and more precisely
ppdev->pldev->pfn.EnableSurface(), fails for these resolutions.
- PDEVOBJ_bSwitchMode(): Set the new video mode, or restore the original
one in case of failure + release the allocated ppdevTmp if previous
calls fail. Also unlock in reverse order of locking order.
- UserChangeDisplaySettings(): In case PDEVOBJ_pSurface() fails (but has
reverted the original video mode), we still need to refresh the
display since the display may have been messed up.
