commit 0f617ddfbb97846b5525d473ad59b570bc432855 Author: Hervé Poussineau <[email protected]> AuthorDate: Sun Mar 20 15:05:12 2022 +0100 Commit: hpoussin <[email protected]> CommitDate: Fri Apr 15 23:09:16 2022 +0200 [WIN32SS] Rewrite EngpCreatePDEV as PDEVOBJ_Create - 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 --- win32ss/gdi/eng/pdevobj.c | 161 +++++++++++++++++++++++++++------------------- win32ss/gdi/eng/pdevobj.h | 6 ++ 2 files changed, 101 insertions(+), 66 deletions(-) diff --git a/win32ss/gdi/eng/pdevobj.c b/win32ss/gdi/eng/pdevobj.c index f6b58b1dd8d..6cc941dabd3 100644 --- a/win32ss/gdi/eng/pdevobj.c +++ b/win32ss/gdi/eng/pdevobj.c @@ -352,83 +352,88 @@ PDEVOBJ_vRefreshModeList( EngReleaseSemaphore(ppdev->hsemDevLock); } -static PPDEVOBJ -EngpCreatePDEV( - PUNICODE_STRING pustrDeviceName, - PDEVMODEW pdm) +PDEVOBJ_Create( + _In_opt_ PGRAPHICS_DEVICE pGraphicsDevice, + _In_opt_ PDEVMODEW pdm, + _In_ ULONG ldevtype) { - PGRAPHICS_DEVICE pGraphicsDevice; - PPDEVOBJ ppdev; - PDEVMODEW newDevMode; + PPDEVOBJ ppdev, ppdevMatch = NULL; + PLDEVOBJ pldev; + PSURFACE pSurface; - DPRINT("EngpCreatePDEV(%wZ, %p)\n", pustrDeviceName, pdm); + TRACE("PDEVOBJ_Create(%p %p %d)\n", pGraphicsDevice, pdm, ldevtype); - /* Try to find the GRAPHICS_DEVICE */ - if (pustrDeviceName) + if (ldevtype != LDEV_DEVICE_META) { - pGraphicsDevice = EngpFindGraphicsDevice(pustrDeviceName, 0); - if (!pGraphicsDevice) + ASSERT(pGraphicsDevice); + ASSERT(pdm); + /* Search if we already have a PPDEV with the required characteristics. + * We will compare the graphics device, the devmode and the desktop + */ + for (ppdev = gppdevList; ppdev; ppdev = ppdev->ppdevNext) { - DPRINT1("No GRAPHICS_DEVICE found for %ls!\n", - pustrDeviceName ? pustrDeviceName->Buffer : 0); - return NULL; + if (ppdev->pGraphicsDevice == pGraphicsDevice) + { + PDEVOBJ_vReference(ppdev); + + if (RtlEqualMemory(pdm, ppdev->pdmwDev, sizeof(DEVMODEW))) + { + PDEVOBJ_vReference(ppdev); + ppdevMatch = ppdev; + } + else + { + PDEVOBJ_bDisableDisplay(ppdev); + } + + PDEVOBJ_vRelease(ppdev); + } + } + + if (ppdevMatch) + { + PDEVOBJ_vEnableDisplay(ppdevMatch); + + return ppdevMatch; } } - else + + /* Try to get a display driver */ + pldev = LDEVOBJ_pLoadDriver(pdm->dmDeviceName, ldevtype); + if (!pldev) { - ASSERT(gpPrimaryGraphicsDevice); - pGraphicsDevice = gpPrimaryGraphicsDevice; + ERR("Could not load display driver '%S'\n", + (ldevtype == LDEV_DEVICE_META) ?
