Otherwise, use software pointer functions.
This fixes graphical glitches on cursor change, when the display driver
provides accelerated pointer functions (DrvSetPointerShape/DrvMovePointer),
but refuses to handle a certain cursor.
These graphical glitches may be reproduced:
- by using Voodoo driver SFFT 1.9
- by using framebuf_new.dll instead of framebuf.dll
- by using the panning driver (setting DefaultSettings.XPanning and
DefaultSettings.YPanning in registry)
- [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.

Search the display mode having the smallest difference with the requested one.
We can then remove the hardcoded values of 60 Hz and 32 bpp by default.
CORE-18189
- use EngpGetDisplayDriverParameters to get display settings from registry
- update searched display settings with the provided ones (+ add missing SEH2)
- then, search exact mode
User can now change only one display setting, without specifying other ones.
This can be configured in registry with DefaultSettings.XPanning and
DefaultSettings.YPanning, which describe the real screen resolution.
DefaultSettings.XResolution and DefaultSettings.YResolution describe
the resolution of the virtual screen.
When changing pointer cursor:
- use PDEV_HARDWARE_POINTER flag if using hardware pointer
- use PDEV_SOFTWARE_POINTER flag if using software pointer
- keep pfnMovePointer as an accelerator to driver function (if available) and never change it
- fix bug (2 pointers) when switching between hardware and software pointer
When moving pointer:
- check PDEV_HARDWARE_POINTER flag to know if we need to call the driver
- check PDEV_SOFTWARE_POINTER flag to know if we need to call EngMovePointer
- search a graphic mode corresponding to real screen resolution (not virtual panning one)
- when capturing the selected mode, copy from input the virtual panning resolution
- when searching the best mode, also try without panning
When changing current devmode, we must not only change ppdev->pdmwDev
pointer, but also update lots of other structures. This work is done by
PDEVOBJ_lChangeDisplaySettings.
CORE-18169
- do not try to remove ppdev from gppdevList if gppdevList is NULL
- do not check (and maybe change) gpmdev, as it should be done only in MDEVOBJ_vDestroy
- introduce LDEVOBJ_vDisableDriver (reversal of LDEVOBJ_bEnableDriver)
- introduce LDEVOBJ_bUnloadImage (reversal of LDEVOBJ_pLoadDriver)
- introduce LDEVOBJ_vDereference, to remove a reference to a LDEVOBJ
Also:
- correctly handle success to unload the image, by removing it from pldev list
- correctly handle failure to unload the image, by re-enabling the driver
- simplify EngUnloadImage, as a wrapper around LDEVOBJ_vDereference
- move LDEVOBJ_ulGetDriverModes lower to prevent forward declaration of
LDEVOBJ_vDereference
Unfortunately, disable driver unloading as long as ntoskrnl can't reload
a driver it just unloaded...
- store the acceleration level in PDEVOBJ
- when searching a pdev, search a pdev with required acceleration level
- disable some functions when not at full acceleration level
(levels 3 and 5 are not implemented)
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.
This function can create a MDEV for the whole display (maybe containing multiple
PDEVs), or update settings of a specific PDEV.
- call PDEVOBJ_lChangeDisplaySettings when switching to graphics mode.
- modify EngpGetPDEV to search requested PDEV only in current MDEV
This will be used (later) to store the list of all enabled display devices.
Add a global variable gpmdev (should really be stored in DISPLAYINFO structure)
Replace global variable gppdevPrimary by pmdev->ppdevGlobal.
- change first argument to be a PGRAPHICS_DEVICE instead of a device name
- add ldevtype (for now, only LDEV_DEVICE_DISPLAY is allowed)
- always pass a devmode if ldevtype is LDEV_DEVICE_DISPLAY
- insert the ppdev into gppdevList on success
- change callers to adapt them to new rules
- Change LDEVOBJ_bEnableDriver to directly take the entry point
(pGdiDriverInfo not required anymore)
- Add LDEVOBJ_pLoadInternal to load and start an internal driver
- 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
LDEVOBJ_bBuildDevmodeList() only queries the available display modes, without
choosing the one to use on the graphic device, and without immediately
creating a PDEV.
Replace first part of EngpPopulateDeviceModeList() function by a call
to this new function LDEVOBJ_bBuildDevmodeList().
Keep second part of EngpPopulateDeviceModeList() function, which
chooses the default display mode.
- implement LDEVOBJ_ulGetDriverModes (which get modes from a not yet loaded driver),
and use it in EngpPopulateDeviceModeList
- remove now useless LDEVOBJ_pdmiGetModes (replaced by LDEVOBJ_ulGetDriverModes)
CORE-17561
Set the API_BITMAP flag for bitmaps created by EngCreateBitmap().
This avoids failure when created bitmap is passed to NtGdiSelectBitmap(), since it checks for this flag and fails if it isn't set.
Otherwise, if failure occurs, the bitmap is hot handled properly.
Setting this flag outside of that function is not an option at all, because it is a public (exported) function, and in many cases it's called directly by the caller (in case with MS DDraw stack, it can be called also by dxg.sys from dxgthk!EngCreateBitmap, which directly calls win32k!EngCreateBitmap).
In particular, it allows Windows XP/2003 DirectDraw stack (ddraw.dll & dxg.sys) to properly work in ReactOS (in software emulation mode), even on real hardware. So now, a lot of DirectX 1-7 apps and games (whose can work withoug hardware acceleation), are working properly with ddraw.dll + dxg.sys replacement! Also Justin Miller (DarkFire01) confirmed that even Direct3D software emulation now also works correctly on real hardware!
It actually should look like '\\.\DISPLAY<n>' (since it comes from user mode),
which the function expects, and not '\\Device\\Video<n>', like done in the
kernel mode. Otherwise, passing wrong name causes a mismatch.
Fix the problem with video device access (failure with status 0xc0000022 when
trying to open it). Hence, it also fixes the following debug log spam:
'err: Could not open device \Device\Video0, 0xc0000022'.
