Issues Resolved

Issues Resolved in Build 1437
Reference No.		Description		Affected Component(s)		Affected OS(s)		Affected Project(s)
BugID: 2551349		Intermittently changing resolutions for TV display causes corruption		Soft BIOS,		Windows* XP, Windows Vista*,		Intel® G965 Express Chipset,
Resolution Description: Root Cause: Code changes have been made to honor the SPD I2Cspeed which is read by vbios from the ADD2 Card. the interfaces have been defined, and data is now obtained from vbios
BugID: 2553815		X61T: PC-Doctor detects V-mem error when image rotated 180deg		Rotation,		Windows Vista, Windows Vista-64,		Intel® GM965 Express Chipset,
Resolution Description: Root Cause: Application was trying do the few blts, ColorFill operations on the FB and then was comparing by drawing it on the system memory. Was failing while doing the ColorFill operation at 90,180 and 270 degree rotation angles because In the __KmGen4SetPresent3DColorFillState function, while setting the ColorFill states we check that if the rotation angle is other than the identity, then we rotate the Destination rectangle according to the Rotation orientation and while setting the vertices for destination rectangle we were setting the vertices of the unrotated rectangle(primitiveRect) which is wrong. So set the vertices of the Dsetination Rectangle according to the rotated rectangle.
BugID: 2554695		(SD-Etude) Video playback flashes when play DVD on Aero Disable mode.		DVD,		Windows Vista, Windows Vista-64,		Intel® GM965 Express Chipset,
Resolution Description: Root Cause: Certain GetResourceXXX functions were added to handle temporary resources more easily and some code cleanup was done to use these functions. During that cleanup, the renderAllocationIndex was incorrectly set using the new GetResourceAllocationIndex() function.
BugID: 2555089		OpenGL* issue -> Error on running bitmap2.exe with Windows* XP SP2 on Intel® Q965 system		OpenGL*,		Windows Vista, Windows XP,		Intel® 3 Series Chipset Family, Intel® G965 Express Chipset,
Resolution Description: Root Cause: DrvCopyContext() is not implemented. Solution: Add implementation for the function. NOTE: The current solution does not fix the problem for Gen3 and Windows* XP. All others should be fixed
BugID: 2555193		Update Denoise / Detail Kernels for UYVY Support		DVD,		Windows Vista, Windows Vista-64,		Intel® G965 Express Chipset, Intel® G965 Express Chipset, Intel® GM965 Express Chipset,

BugID: 2555418		Intel® GM965 Express Chipset CxSR Dynamic watermark bug fix.		Power Conservation,		Windows Vista, Windows Vista-64, Windows* XP, Windows* XP-64,		Intel® GM965 Express Chipset,
Resolution Description: Root Cause: CxSR dynamic watermark bug fix for Intel® GM965 Express Chipset. Intel® GM965 Express Chipset: In addition to normal restrictions testing and CUI dynamic enabling/disabling testing, please also do the Windows Vista* cursor workaround test as follows: 1) Windows Vista* Aero 2) Open Window 3) Drag Window around and make sure that mouse cursor does not disappear.
BugID: 2555452		The corruption is displayed after resuming the system from Suspend state (S3).		GMM,		Windows Vista, Windows Vista-64,		Intel® 945GM Express Chipset, Intel® 945G Express Chipset,
Resolution Description: Root Cause: Corruption during sleep and hibernate on Intel® 945GM Express Chipset Windows Vista* on 15.8 build This affects only Intel® 945G Express Chipset and Intel® 945GM Express Chipset.
BugID: 2555696,2555705		W - WLK - Graphics Bus Transfer - Failing Log		Resource Manager,		Windows Vista*-64,		Intel® 3 Series Chipset Family
Resolution Description: Root Cause: Added GMM limit check before evaluating modes to be added to mode list Added Function: BwGMMLimitChecks Description: Checks if the Mode is within the GMM limit Notes: Till Intel® GM965 Express Chipset including Bearalke MAX Mode supported = 2048x1536
BugID: 2555916		Software(Nero) install issue with G35 Gfx driver		NT - miniport,		Windows Vista, Windows Vista-64,		Intel® 3 Series Chipset Family, Intel® G965 Express Chipset, Intel® GM965 Express Chipset,
Resolution Description: Root Cause: The issue was happening because of PCI Config accesses as part of a WA while setting text mode in SoftBIOS. This happens only in the path of ResetDevice as at this point DXGK exposed function pointer addresses are unmapped causing invalid pointers for PCI Config accesses. However, this did not happen on CRBs, so it purely depends on the timing of ResetDevice getting called. The fix for this issue is to use HakGetBusDataByOffset and HalSetBusDataByOffset DDIs for accessing PCI Config space in ResetDevice handler when the call is coming for Shutdown or Restart instead of Dxgk based interfaces.
BugID: 2556358,2556655,2556685		[15.8] Fix hanging overlay playback		KMD Render,		Windows Vista, Windows Vista-64,		Intel® G965 Express Chipset, Intel® GM965 Express Chipset,
Resolution Description: Root Cause: Overlay playback was hanging in apps when skipping forward or backwards. An escape call to verify whether the resources were available for lock was failing because we were using the wrong register in Gen4 after a change for Gen5. Updated variable use to reflect correct register
BugID: 2556684,2556686,2556689		Persistence w/a to fix DL issue:2554772		CUI2,CUI2.5,		Windows Vista, Windows Vista-64,		Intel® GM965 Express Chipset,
Resolution Description: Root Cause: With LFP and DL in DDC, on resuming from hibernate, display comes up in LFP + CRT DDC, highly sporadic and was reproducible only on Rishi’s setup, on hibernate, debug outcome as follows ·DL issues a detach call (to shutdown all DL specific services) on resuming from hibernate ·CUI queries driver for the currently connected devices, driver reports LFP and CRT ·Since call for attach has not yet happened from DL, CUI drives DDC on LFP + CRT (next available device), ·While saving this config, CUI once again queries driver for connected devices, which is reported as DL display (as attach has now happened), LFP & CRT, ·CUI saves LFP + CRT DDC in registry (thus corrupting registry) hence the issue, purely a synchronization issue, hence sporadic
Issues Resolved in Build 1413
Reference No.	Description		Affected Component(s)		Affected OS(s)		Affected Project(s)
BugID: 2553055	CUI not loading in desired language once it is set in Regional and Language Tab		CUI2,		Windows* XP, Windows* XP-64, Windows Vista, Windows Vista-64,		Intel® 945GM Express Chipset, Intel® GM965 Express Chipset,
Resolution Description: Root Cause: MUI support for Windows Vista*: With these changes, whenever user changes the OS display language in Regional and Language Settings Tab in Control Panel and perform a logoff and logon, CUI will show up in new language. If it is not one of the supported languages, then CUI would show up in English. These changes also apply for Non MUI OS also. In this case, there is no option to change OS display language, but user can change the default locale. If it is changed and user performs a log-off and log-on, CUI will show up in that language.
BugID: 2550940	Warning message is not displayed after launching TV Wizard application via WINDOWS MEDIA* CENTER at CRT+Digital TV DDC mode.		TV Wizard,		Windows Media Center,		Intel® 3 Series Chipset Family,
Resolution Description: Root Cause: In 10ft with Digital TV as one of the active display in MDS configurartion, if we try to Launch 10ft TVWizard, its not showing the Warning message as expected In MyApp.xaml.cs. When the page has to be initialized, there is a creation of "PageDefault" object and intializtion of the same which internall is corrupting the actual retrieved data of "data.TvObj.IsTVDualActive". Fix Description: On the first initialization in MyApp, check for "data.TvObj.IsTVDualActive" and then procede with other intializations. This will avoid the corruption of data and the warning message will be displayed.
BugID: 2553772	glCopyPixels( ) failure when default glPixelZoom(1,1) is active		OpenGL*,		Windows* XP, Windows* XP-64,		Intel® G965 Express Chipset,
Resolution Description: Root Cause: Drawing into double buffered OpenGL window with glDrawBuffer( ). Then use glCopyPixels( ) to move e.g. backbuffer contents to front buffer. problem seems to happen when glPixelZoom is (1,1). glFlush and glFinish do not help make result visible. Fix Description: Set the gc->drawable->flushPending flag after performing CopyPixels (BLT) operation. It will trigger the update of drawable at the next glFlush/glFinish.
BugID: 2553745	TDR occurs on resume from S3 resume		Direct3D*,GMM,KMD Render,		Windows Vista, Windows Vista-64,		Intel® 945GM Express Chipset, Intel® GM965 Express Chipset,
Resolution Description: Root Cause: Driver was not saving stolen memory on S3 events. Fix Description: Updated power management logic to unconditionally save/restore stolen memory on S3 events. Windows Vista* Hybrid Sleep feature implies that system could potentially go into hibernate after being in sleep for a duration of time. Driver wouldn't be notified in that event.
BugID: 2554499	Compare with PV15.6, DVD quality is poor(Flicker/Jaggy)		DVD,		Windows Vista, Windows Vista-64,		Intel® G965 Express Chipset, Intel® GM965 Express Chipset,
Resolution Description: Root Cause: When DenoiseV2 / DetailV2 Support was added code cleanup was also done. This unintentionally caused the MODEAST Motion History Buffer to be initialized to the default value for every frame instead of just once. This causes deinterlacing artifacts, especially in the HQV Color Bars test. Fix Description: The fix was to only initialize the Motion History buffer once.
BugID: 2519373, 2553176	It has some garbage on WinDVD5 at the start of DVD		DVD,		Windows* XP,		Intel® G965 Express Chipset, Intel® GM965 Express Chipset,
Resolution Description: Root Cause: Additional binding table indices for PL output were added, but the binding table and surface state heap sizes were not adjusted for this change so that the right amount of space could be allocated and initialized. Fix Description: This issue is resolved by updating the sizes of the binding table and the surface state heap.
BugID: 2551221	Noisy screen appears on CRT with High resolution and High refresh rate.		Soft BIOS,		Windows Vista*,		Intel® GM965 Express Chipset,
Resolution Description: Root Cause: The cursor SR WM values were calculated incorrectly in driver. Fix Description: Made following changes: 1) While calculating cursor WMs, we need to consider FIFO size of already enabled display planes. Earlier we were using FIFO size for cursor. 2) For TLB adjustment, we now check the whether 8 lines fit in FIFO, instead of 7.
BugID: 2554695	Video playback flashes when play DVD on Aero Disable mode.		DVD,		Windows Vista, Windows Vista-64,		Intel® GM965 Express Chipset,
Resolution Description: Root Cause: GetResourceXXX functions were added to handle temporary resources more easily and some code cleanup was done to use these functions. During that cleanup, the renderAllocationIndex was incorrectly set using the new GetResourceAllocationIndex() function. Fix Description: This resolution is to fix the renderAllocationIndex and remove function overloading for the GetResourceXXX functions.
