Issues Resolved

Issues Resolved in Build 1554
Reference No.	Description	Affected Component(s)	Affected OS(s)	Affected Project(s)
Bug ID: 2558984	DVI hotplug doesn't work.	Soft BIOS	Windows Vista*	Mobile Intel^® 45 Series Chipset Family
Root Cause: No longer seen with latest driver
Bug ID: 2559623	Gfxtray error pops up during uninstallion	Switchable GFX	Windows Vista*	Mobile Intel^® 45 Series Chipset Family
Root Cause: Igfxtray and hkcmd being launched during un-installation. But the uninstaller has already removed those files. This will result in an error pop up. As a work around to this issue, suppress the error pop up.
Bug ID: 2559833	French localization translation error in driver	Loc Translation	Windows Vista*	Mobile Intel^® 45 Series Chipset Family
Root Cause: No longer seen with latest driver
Bug ID: 2559880	Re-Open: The error " Task Scheduler Engine has stopped working" occurs when you overwrite the PV15.8.2 driver.	CUI2	Windows Vista*	Mobile Intel^® 945 Express Chipset Family
Root Cause: Multiple mode set calls from TMM causing a stack overflow. In SetConfiguration, return Status_Applied to make sure TMM does not make any more calls. Persistence will anyway take over the mode set part.
Bug ID: 2560853	Extended Desktop monitor position is not reserved after resume from Sleep by LCD Lid.	CUI2.5	Windows Vista*	Mobile Intel^® 945 Express Chipset Family Mobile Intel^® 45 Series Chipset Family
Root Cause: EDS position was not persisted for lid event when logon screen is enabled. The issue was happening because with logon screen present CDS calls fails by not applying the position data and reverts back to the default 1- 2 position. After trying out Windows* XP SyncOSdriverThread WA for Windows Vista, exposed that in Windows Vista we are already taking care of this scenario in ApplyConfigWindows Vista* . This was not getting executed because everytime when the CDS fails when setting position data , we used to return as success where it will update the registry and stop the process. So the fix is returing failure when CDS_TEST fails. This would allow CDS to apply right data after login which is handled in WM_WTSSESSION_CHANGE.
Bug ID: 2561005	Screen blackout in Glaze 3D Presets test when select 3, Q45	GHAL3D State	Windows Vista*	Mobile Intel^® 45 Series Chipset Family Intel^® 4 Series Chipset Family
Root Cause:
Bug ID: 2561099	LFP display is flickering when playing some online game in battery mode.	Power Conservation	Windows Vista*	Mobile Intel^® 45 Series Chipset Family
Root Cause: Issue not seen with latest driver
Bug ID: 2561700	Green noise is displayed on H/W overlay.	KMD Render	Windows Vista*	Intel^® 965 Express Chipset Family-G Mobile Intel^® 45 Series Chipset Family Intel^® 4 Series Chipset Family
Root Cause: UMD Overlay was destroying overlay surfaces before turning off overlay. This caused the surfaces to become invalid and HW was still scanning. changed order to shutoff overlay then destroy intermediate surfaces. Overlay path was not properly waiting for HW to complete shutdown. Need to wait for HW to complete shut off before destroying intermediate surfaces. Scanned Surfaces were being destroyed before Overlay Hw was completely turned off. modify KMD overlay code to wait for HW to turn off before returning from DestroyOverlay.
Bug ID: 2742322	When WinDVD BD moves between CRT and LCD, BSOD happens.	KMD Render	Windows Vista* Windows Vista*-64	Mobile Intel^® 45 Series Chipset Family
Root Cause: Visible Framedrop happens when we overlap any window over fullscreen videoplayback.Issue happens when we play BD with WinDVD or normal DVD with Windows media center. Comparing the Vtune samples during normal playback and window overlapped playback shows more bandwidth is consumed by Igdumd32. Couldnt expand it to function level in VTunes.Frame drop is visible with or without HW decoding when the window is overlapped. Looks like issue happens only when Direct3D* rendering happens parallel to the playback.Similar issue exists in Direct3D* performance for Mobile Intel^® 965 Express Chipset Family. Intermediate surface pointers were not being set to NULL when freeing, so there were some cases where surfaces would attempt to be freed multiple times causing the BSOD. Fix is to set pointers to NULL after freeing.
Bug ID: 2743202	For CRT hotplug/unplug cases, we need to receive a CommitVidPn call to notify proxy	N/A	Windows Vista*	Mobile Intel^® 45 Series Chipset Family Montevina
Root Cause: If the system was booted up in dGPU, the persistence was not functioning when we switch to iGPU. When the persistence module gets initialized, it’ll check whether display is on dGPU. Then rest of the initialization was skipped if it’s on dGPU. The skipped initialization includes the DeviceChange notification registration and PersistManager initialization. This will result in persistence being inactive on all scenarios. So to fix it, if the initialization was skippied on the boot up, the initialization is redone after a GPU switch.
Bug ID: 2787298	DP-Cannot Display Change through DP-DVI or DP-HDMI Dongle by ACPI Hotkey correctly	Soft BIOS	Windows* XP Windows Vista*	Mobile Intel^® 45 Series Chipset Family
Root Cause: In VBTMANAGER_ParseToggleTable, the bIntelPipeSelectList values are getting assigned wrongly for this particular entry mentioned in the bug The bIntelPipeSelectList values are not cleared in inner loop (it is cleared outside) so these values are kind of loop back for next iteration and previous values are getting assigned for next entry which is creating this issue. Code has been modified to clear the bIntelPipeSelectList values in the inner loop in VBTMANAGER_ParseToggleTable().
Bug ID: 2787364	Some information of Inter^® GMA driver not list properly	Loc Translation	Windows Vista*	Intel^® 4 Series Chipset Family
Root Cause: The defect is caused by ENU resource. Since Development team has no plan to fix the issue soon, pilot fixed in both Chinese. Unchecked Do Not Translate box for the strings displayed in the System Report, copy the source strings and insert the \t or \t\t or \t\t\t to be aligned properly throughout the file, not only the first section of the System Report mentioned by OEM.
Bug ID: 2787405	ILDB's effect is not effective.	DVD	Windows Vista*-64	Intel^® 4 Series Chipset Family
Root Cause: The external registry key is in path HKEY_LOCAL_MACHINE\Software. On a 64bit platform, there are two completely different HKEY_LOCAL_MACHINE\Software views for 32bit and 64bit. The ILDB registry key is written in 64bit registry key view through inf file. A 32bit application such as WinDVD invokes 32bit driver model which reads the registry keys from the 32bit view, so it doesn’t see the correct path. So on a 64bit system, we need to force to read 64bit regsitry key view in our driver 32bit dll
Bug ID: 2787499	[extended display mode]BSOD will happen when two movies are played.	KMD Render	Windows Vista*	Mobile Intel^® 45 Series Chipset Family
Root Cause: Visible Framedrop happens when we overlap any window over fullscreen videoplayback.Issue happens when we play BD with WinDVD or normal DVD with Windows media center. Comparing the Vtune samples during normal playback and window overlapped playback shows more bandwidth is consumed by Igdumd32. Couldnt expand it to function level in VTunes.Frame drop is visible with or without HW decoding when the window is overlapped. Looks like issue happens only when Direct3D* rendering happens parallel to the playback.Similar issue exists in Direct3D* performance for Mobile Intel^® 965 Express Chipset Family. Intermediate surface pointers were not being set to NULL when freeing, so there were some cases where surfaces would attempt to be freed multiple times causing the BSOD. Fix is to set pointers to NULL after freeing.
Bug ID: 2787562	When PC start up, green horizontal noise happens three times.	Video BIOS	Windows Vista*	Intel^® 4 Series Chipset Family
Root Cause: In VBIOS during set-mode sequence, SDVO Ports are turned off. As soon as it is turned off, GMCH is putting off the data first and after around 2ms backlight is turned off. During this 2ms time, the invalid data from GMCH is seen as the green flicker. Later in VBIOS code, we are sending the set ACTIVE_OUTPUTS_OFF opcode to the SDVO card, which also effectively turns off backlight if it was on. In driver code, the set ACTIVE_OUTPUTS_OFF opcode is sent first, so that backlights are off and later SDVO ports are turned off. So issue is not seen there. Fixed by disabling SDVO ports after ACTIVE_OUTPUTS_OFF opcode is sent.
Bug ID: 2788146	DP - Display loses sync and cannot work after repeat reboots with E1909 DisplayPort Panel	Video BIOS	Windows Vista*	Intel^® 4 Series Chipset Family
Root Cause: If AUX EDID read fails, retry 3 times until reporting EDID read failure in VBIOS.

Issues Resolved in Build 1545
Reference No.	Description			Affected Component(s)		Affected OS(s)		Affected Project(s)
Bug ID: 2787522	Only one scheme is displayed on right click menu and task tray menu.			CUI2.5		Windows Vista* Windows* XP		Mobile Intel^® 45 Series Chipset Family
Root Cause: Local variable not initialized before validating different schemes To fix: Initialized the local variable properly so that right values are picked up every time
Bug ID: 2787356	Cannot set DRRST feature to 'unchecked' in CUI by default as described in PRD Req#2G39226			Power Conservation		Windows Vista* Windows Vista-64 Windows XP		Mobile Intel^® 45 Series Chipset Family
Root Cause: The functionality of the 'DPSCheckboxDefault' INF option was broken. This is supposed to allow the OEM to program the FIRST BOOT (after fresh install) setting of the DPS check-box. But, it was getting overriden by the default first boot power plan. To ensure that it’s not overridden anymore, a special customization section for first boot after fresh install was applied.
Bug ID: 2787347	Boot screens not visible with DP monitor connected			Video BIOS		Windows Vista*		Intel^® 4 Series Chipset Family
Root Cause: Missed to disable DP port control registers before planes are disabled and pipe timing registers are set in in VBIOS programming sequence.
Bug ID: 2787275	Deinterlaced frames are displayed in an incorrect order			DVD		Windows Vista*		Intel^® 4 Series Chipset Family
Root Cause: Enabled Fast Composition Support through 3D pipeline and defined the proprietary API/DDI interface. Also, established the entire new HAL level 3D pipeline programming.
Bug ID: 2742978	When playing AVI movie, the color control function doesn't work correctly.			DVD		Windows Vista* Windows Vista*-64		Mobile Intel^® 45 Series Chipset Family Intel^® 4 Series Chipset Family
Root Cause: ProcAmp, Denoise, and Detail were always incorrectly enabled during Post-Processing, regardless of the input format. Therefore, the bug fix is to block ProcAmp, Denoise, and Detail for RGB Input.
Bug ID: 2742284	Could not hide " Twin" item on CUI Display Device dialog by inf customization.			CUI2.5		Windows Vista* Windows Vista-64 Windows XP Windows* XP-64		Intel^® 4 Series Chipset Family
Root Cause: Added Customization options for operating mode that was missing in UI
Bug ID: 2561686	Full screen check box in s-video TV settings is non functional			CUI2.5		Windows Vista*		Mobile Intel^® 45 Series Chipset Family Montevina
Root Cause: Driver was not receiving the mode set from CUI.
Bug ID: 2560637	BSOD 0x0A or 0x1A when plugging HDMI TV to System and setting Extend desktop (HDMI as primary and internal LCD as secondary.)			Audio.Driver		Windows Vista*		Mobile Intel^® 45 Series Chipset Family
Root Cause: Silent Stream feature was causing BSOD. To fix: improved unsolicited reponse handler, improved work item management and sub device management.
Bug ID: 2560526	EDID Related Behavior in HDMI Compliance Test fails.			Soft BIOS		Windows Vista*		Mobile Intel^® 45 Series Chipset Family
Root Cause: The GMBus0 register was incorrectly being reset during a transaction.
Bug ID: 2560414	The " Aspect Ratio" Options is different between VGA and DP Mode in Windows* XP& Windows Vista*			Soft BIOS		Windows* XP Windows Vista*		Intel^® 4 Series Chipset Family
Root Cause: Compensation options were being shown on DisplayPort. However, this there was no need for this since scaling is not enabled on DisplayPort.
Bug ID: 2559690	Walle game has screen flashes/sync issues when in battery mode in Windows Vista			Power Conservation		Windows Vista*		Mobile Intel^® 45 Series Chipset Family
Root Cause: For fixed panels the PC component was sending the native resolution instead of the actual resolution. Some portions of the watermark programming require the actual resolution. Changing over to a methodology of having SoftBios get the native resolution and actual pixel depth for non-cursor SR watermarks.
Bug ID: 2558841	The system is not able to change brightness after resuming from Suspend or Hibernate.			Power Conservation		Windows Vista*		Mobile Intel^® 945 Express Chipset Family
Root Cause: After resume, the backlight control bit was not getting set properly.
Bug ID: 2556822	Grammar and translation is incorrect on French OS.			Loc Translation		Windows Vista*		Mobile Intel^® 45 Series Chipset Family Mobile Intel^® 965 Express Chipset Family Intel^® 4 Series Chipset Family

Issues Resolved in Build 1537
Reference No.	Description			Affected Component(s)		Affected OS(s)		Affected Project(s)
Bug ID: 2554984	Show horizontal mode in extented vertical pivot			CUI2		Windows Vista* Windows Vista*-64		Intel^® 3 Series Chipset Family Mobile Intel^® 45 Series Chipset Family
Root Cause: Rootcause:the conditions for " PriRotaed" abd " SecRotated" was not supporting in case when rotation is changed from 0 to 90/270 degree. Removed the variables used earlier to track the rotation of primary and secondary and intercahing the X and Y resolution.T The variables were used only in Exteded desktop case and the variables were not serving the purpose in case of the orientation changed. Condition is modified by adding " ROTATION_90" and " ROTATION_270" for interchanging X and Y resolution in case of setting the position.
Bug ID: 2555381	Screen Corruption while playing Motocross Madness 2			Direct3D*		Windows Vista*		Intel^® 3 Series Chipset Family Intel^® 965 Express Chipset Family Mobile Intel^® 45 Series Chipset Family Mobile Intel^® 965 Express Chipset Family Intel^® 4 Series Chipset Family Intel^® 945 Express Chipset Family
Root Cause: The clear code regressed and started returning E_FAIL instead of S_OK when the Clear call specified a NULL pRects.
Bug ID: 2557400	[EL/G45/Windows Vista*32/15.9-34V] Incorrect localization(korea) in CUI			Loc Translation		Windows Vista*		Intel^® 4 Series Chipset Family
Root Cause: Reverting back to font size from 10 to original size 9 in IIDS(152)failed getting rid of the extra space. Hence, moved all the corresponding controls to the right leaving equal amount of space on both sides. However, still need to resolve this issue with font size. Need to figure out why rolling back to original font size does not remove the extra space on the right.
Bug ID: 2559407	System can not persist display mode and resolution after resumed from S3			CUI2.5		Windows* XP Windows Vista*		Mobile Intel^® 45 Series Chipset Family
Root Cause: RootCause: Comparision with current config not required. Following are the reasons: (a) This path is hit only when Logon screen turned on and the previous apply config fails. So we have to try applying the config, persistence wants to apply based on the earlier configuration. (b) In the case of above issue, actual data in the registry is set as LFP SPSD after processing the POWER EVENT and the data in the registry is modified as LFP - SPSD. So at this point, when we try to compare the persistence data with the actual data, both are same and hence the call fails and no setmode is issued to the driver. Removed the comparision checks with current configuration.
Bug ID: 2559644	No response for a while after switching to iGPU.			Switchable GFX		Windows Vista*		Mobile Intel^® 45 Series Chipset Family
Root Cause: Implemented appropriate kernel synchronization mechanism for threads while spinning for lock. Appropriate sync objects are used.
Bug ID: 2559684	Overlay colorkey not updated when PowerDVD Cinema toolbar presents			N/A		Windows Vista*		Mobile Intel^® 45 Series Chipset Family
Root Cause: Application has a lot of transparencies which causes the OS to break up present into > 64 subrectangles. Changed to behave as normal present would which is to return and continue until all rectangles are completed.
Bug ID: 2559952	The video color is abnormal when using QP to play video recorded by itself.			Media Kernels		Windows Vista* Windows Vista*-64		Mobile Intel^® 45 Series Chipset Family
Root Cause: Modeast kernel cannot handle the source rectangle starting from ODD coordinate for packed format. Driver needs to adjust the left coordinate to EVEN number.
Bug ID: 2560145	WINDOWS VISTA*: Hot-key display switch does not function after resume from S4 with external VGA attached			NT - miniport		Windows Vista*		Mobile Intel^® 45 Series Chipset Family
Root Cause: In Windows Vista* SP1, OS doesn't sends " Sleep" as the reason for resume instead of " Hibernate" for S4 case. Due to this, driver doesn't evaluate _DOS to enable display switching. Evulating _DOS for both S3/S4 case on resume.
Bug ID: 2560570	Hue setting not working between 0 and 49 in Windows Vista*			KMD Render		Windows Vista*		Intel^® 3 Series Chipset Family Intel^® 965 Express Chipset Family
Root Cause: Hue was being defined as an unsigned instead of a signed variable.
Bug ID: 2560917	Boot as iGPU mode causes that system becomes busy and does not respond from 1min to 10min			N/A		Windows Vista*		Mobile Intel^® 45 Series Chipset Family
Root Cause: Implemented appropriate lock mechanism Appropriate sync objects are used.
Bug ID: 2560987	Long resume time from S3			NT - miniport		Windows Vista*-64		Mobile Intel^® 45 Series Chipset Family
Root Cause: Added optimization for memory copy in softbios.
Bug ID: 2561206	External display has no system password screen after S3 resume			N/A		Windows Vista* Windows Vista-64 Windows XP Windows* XP-64		Mobile Intel^® 45 Series Chipset Family
Root Cause: During S3 resume, the DP clocks were not restored properly. So, the display was getting blank on the DP panel. Added code to reprogram the DP AUX clocks if they are not found to be programmed properly.
Bug ID: 2561364	Render Freq changes after Sleep/Resume.			Power Conservation		Windows Vista* Windows* XP		Mobile Intel^® 45 Series Chipset Family
Root Cause: Fixed the sequence for P-State retore
Bug ID: 2561711	A screen collapses after resolution was changed to 1920*1200 on CRT only mode.			Soft BIOS		Windows* XP Windows Vista*		Mobile Intel^® 45 Series Chipset Family
Root Cause: Root-cause – SB was not reporting 64BPP modes to RM, for pruning based on dotclock limitations. Hence SB mode table always had unsupported 64BPP modes and this was being shown up in CUI. On applying, it was causing corrupted screen. This issue was particularly seen in low power mode where RM pruning is having a significant role because the platform may not even support the modes well below the EDID capability of the display. Fix:- SB will be adding 64BPP modes as well in the RM mode table for pruning
Bug ID: 2742292	System hang by playing H.264 and hib/res on IRX-4410			Power Conservation		Windows Vista* Windows Vista*-64		Mobile Intel^® 45 Series Chipset Family
Root Cause: On power down, the PC policy states for RS is out of sync with the actual HW state. Upon resume, RS HW state is on but RS SW policy is inactive. When the DXVA AVC/VC1 notification is processed to disable RS, the handler sees that the policy is already in inactive state so no action taken. Hence RS is still enabled while playing BD --> LRI related hang issue. Solution: On power down RS should not be handled by PC policy handler since it is not mode or display configuration dependent. This fixes the out of sync issue. Root cause: Upon entering D3 state, driver saves the HW state and then calls the policy handler to disable all PC features. Upon resume RS HW state is restored but RS policy remains inactive since it is not reset by mode or display configuration event. When UMD DxVA sends notification to disable RS, no action was taken since the policy sees it in inactive stage --> RS remains enabled --> LRI/AVC/VC1 hang issue. Resolution: Remove policy handling of RS in power down since it is not mode or display configuration dependent.
Bug ID: 2742763	[OGL2.0] Errors running glViewer failed with all different versions of openGL selected			OpenGL*		Windows Vista*		Mobile Intel^® 45 Series Chipset Family
Root Cause: The invalid pixel format error message reported in HSD 274263 is an app issue. The app uses unsupported pixel format WGL_BIND_TO_TEXTURE_RGBA_ARB in Intel driver and it does not handle the error code return from Intel driver correctly.
Bug ID: 2743086	CUI 2.5 - Unable to remove Information Button when customizing INF			CUI2.5		Windows Vista* Windows Vista*-64		Intel^® 4 Series Chipset Family
Root Cause: Root cause: From 2.5 information button no longer displays string hence customization was not taken care in this case hence the bug. Check if IDS_INFO string is null, if null then hide the button

Bug ID: 2559431	Display is fragmented, when we play " Unreal Toumament 3"	Direct3D*	Windows Vista*	Mobile Intel^® 965 Express Chipset Family
Root Cause: Texture L8 was not set for sampler s4, because of failed getstateprocessorhandle - there was no conversion for L8_SRGB available. Doing this conversion was only option when SRGB write was enabled resolution: Adding code to get stateprocessorhandle without srgb write if first try failed fixes this issue
Bug ID: 2559572	The game UBISOFT [SURF'S UP] freezes.	Direct3D*	Windows Vista*	Mobile Intel^® 45 Series Chipset Family Intel^® 4 Series Chipset Family
Root Cause: When the application disables an index buffer, the D3D component of the driver needs to notify GHAL3D that the index buffer is disabled. If it doesn't do this, on Vista, GHAL3D will put this stale allocation handle for the index buffer in the command buffer allocation list. This will cause RenderCb to fail if the application has also deleted the index buffer resource before the next draw call and hasn't bound a new index buffer in it's place.
Bug ID: 2559709	The DVD playback is not displayed.	KMD Render	Windows Vista*-64	Mobile Intel^® 45 Series Chipset Family
Root Cause: Because of the way a 64-bit build pads structures, the members for the 32-bit build and the 64-bit were at different locations. This caused a mix up in data when a 32-bit user mode application was accessing a 64-bit KMD through escape calls.
Bug ID: 2559942	Media Player clips not playing correctly on Broadwater (G965 & G35)	DVD	Windows Vista*	Intel^® 965 Express Chipset Family Mobile Intel^® 965 Express Chipset Family

Bug ID: 2553333	When trying to run an OGL application through web browser, the app crashes on Windows Vista* drivers only	OpenGL*	Windows Vista*	Mobile Intel^® 965 Express Chipset Family
Root Cause: The applet detaches current rendering context from device context. The OGL driver tries to use some rendering context owned data during this operation causing invalid dereferences Solution: Update driver code so that window description is read from drawable description and GL context updates its data from drawable data.
Bug ID: 2554732	“Display driver igfx stopped responding..." Error is seen when playing media in DC mode. It also shows randomly while system is sitting idle.	Power Conservation	Windows Vista*	Mobile Intel^® 45 Series Chipset Family Montevina
Root Cause: Issue is root caused to pipe interrupt handler clearing first level pipe event in second level event interrupt enabling routine. This is an issue when the pipe event interrupt is being shared by more than one interrupt sources. The TDR happens when the interrupt enabling invoked by DPST coincides with a VBlank event, which leads to pipe event status cleared before it could be serviced hence reporting a TDR.
