CORE-18221 Load the DirectX graphics kernel driver (dxg.sys) by win32k at WINSRV initialization time, in NtUserInitialize(). Keep it always loaded in memory, as on Windows, instead of loading it only by DirectX dlls. This fixes the problem of acessing this driver: we need only to call DxDdEnableDirectDraw() and do other stuff when DirectDraw/Direct3D is required by anything. In other cases, it is called from win32k PDEV functions when changing display mode (as in Windows). Since it's used by other things too, it needs to be always loaded. Otherwise, if it's not loaded, its APIs are not accessible when needed, and execution fails. For example, it fixes display mode change problem in VMWare, when a new mode fails to be applied. Indeed, when it manages DirectDraw stuff, it calls DXG routines, and therefore fails if dxg.sys isn't loaded in memory at this moment. - Implement InitializeGreCSRSS() initialization routine, that initializes supplemental NTGDI/GRE data once CSRSS and WINSRV are loaded: * Call DxDdStartupDxGraphics() inside it, which loads dxg.sys. * Additionally, move fonts and language ID initialization there, from win32k!DriverEntry. Confirmed by analysis on Windows. - Call InitializeGreCSRSS() in NtUserInitialize() main initialization routine (called by WINSRV initialization). Moved to NTGDI from previously NTUSER place: Co-authored-by: Hermès Bélusca-Maïto <hermes.belusca-maito@reactos.org> |
