Bug ID: 2787472

Blackscreen seen when reboot from installing driver -Accenture

NT - miniport

Windows Vista*

Mobile Intel® 965 Express Chipset Family

Root Cause: 

 

Made changes to Monitor mode list enumeration logic, where in now we'll start recommending LFP Edid mode to OS

Bug ID: 2807426

TV format can not be retained after toggle one cycle via Fn+F4

CUI2.5

Windows Vista*
Windows* XP

Mobile Intel® 4 Series Chipset Family

Root Cause: 

 

The regqueryvalueex call used for reading registry was failing due because we were passing the size to be read as zero fixed it.

Bug ID: 2808183

Increasing the number of Albums in Niveus Movie Library WINDOWS MEDIA* CENTER Plugin decreases performance when cycling

Direct3D*

Windows Vista*

Intel® 4 Series Chipset Family

Root Cause: 


The problem is that Windows Media Center sends primitives to draw all titles in every frame.

Verices are processed by UMD, which is a bottleneck and clipped in HW.
The fix was to clip veritices as soon as possible to limit the unnecessary processing in UMD. This can be achieved with software vertex processing pipeline.

Bug ID: 2808186

Bug ID: 2808252

When we do S3 aging test , the desktop will have some black points with 3GB memory

GMM

Windows Vista*
Windows Vista*-64

Mobile Intel® 4 Series Chipset Family

Root Cause: 

 

Found race condition exposed in L-shape configs causing mis reads.

What we suspect was happening was that the driver would map a pte backing store into GTT and immediately read the corresponding gfx memory through PCI aperture. That should be fine b/c the GTT is mapped UC. However, that mapping is some how behaving like a WC (write combined) mapping. We believe the pte write did not complete before the gfx memory read so driver read from the old pte backing store, causing corruption or black dots.

By putting an mfence() after the last GTT write operation, it flushes the CPU memory cache guaranteeing the pte is written out before the driver reads the gfx memory.

Bug ID: 2855303

In External mode, we can't use Intel Driver to switch display to NB LCD mode.

iHDMI - [Channel- P5QL-EM -G43] DVI no display

Video BIOS

Free DOS
Windows Vista*
Windows Vista*-64
Windows* XP
Windows* XP-64

Intel® 4 Series Chipset Family

Root Cause:

VBIOS was blindly scanning for the CEA extension blocks to check if the panel is HDMI or not, without first checking if the extension flag in EDID (127 byte) is greater than zero as how driver was doing. This particular panel did have a CEA extension block with a VSDB showing a HDMI header, even though it’s not a HDMI panel. VBIOS hence interpreted based on this info that this is a HDMI panel and did not disable NULL packet enable and Audi output from the port control register hence no display when HDMI/DVI was chosen in VBT.
When DVI only was chosen in VBT, the device attached was not getting set hence no enumeration of the device. This is because of the same above mentioned reason, the HDMI display attached status wrongly came as true but since the HDMI compatibility bit was not set in VBT (DVI only was chosen), the device attached bit was not set hence the device did not get enumerated at all which means the port control register was not getting enabled.

Fix:- The correct fix as how its been done in the driver, is to check if the extension flag is greater than 0 before reading the CEA extension blocks for checking if the panel is a HDMI panel. If the flag shows it has no extension blocks (0), then VBIOS won’t bother to read the extension blocks instead it will just set the carry flag (HDMI display not attached) in the routine aim_Is_HDMI_Display_Attached and return

Bug ID: 2807315

Hidden text in Spore is displayed

Direct3D*

Windows Vista*-64

Mobile Intel® 4 Series Chipset Family
Intel® 4 Series Chipset Family

Root Cause:  


The problem comes from applications that set the ScissorRect to (0, 0, 0, 0). We were subtracting one and passing (o, 0xffffffff, 0, 0xffffffff) down. The fix just checked for 0 and skips the -1.

Bug ID: 2808082

The value of Color Controls is changed by Suspend/Resume.

CUI2.5

Windows Vista*
Windows Vista*-64

Mobile Intel® 4 Series Chipset Family

Root Cause:  


Values are stored wrongly in registries while setting. eg: if contrast = 9.30 it is stored as 9.3000002 and if contrast = 8.74 it is stored as 8.7399998. So, we get rounding problem while retrieving.

Fix: While getting the values from registry add 0.05 and 0.005 to the float values with single digit precision and double digit precision respectively to correct rounding error.

Bug ID: 2808146

Montegi green video with MPEG2 IDCT mode (DXVA1 only)

DVD

Windows Vista*
Windows Vista*-64

Intel® 3 Series Chipset Family

Root Cause:  


The issue occurs in DXVA1 application running on DXVA2 interface only. There is no MPEG2 GUID query mechanism in DXVA1 API, so the invalid GUID may come in DxvaGetDecodeConfigurations after OS mapping to DXVA2 DDI. We need to return DDERR_INVALIDPARAMS for unsupported mode based on sku setting.

Bug ID: 2855340

DF251513 CPU usage at 60% with version 1554 of INTEL graphics driver in Windows Vista* 64 Bits

CUI2.5

Windows Vista*-64

Mobile Intel® 4 Series Chipset Family

Root Cause:

When Igfx persistence got loaded then it will do Initialize Windows Vista* persistence. While doing Init Persistence it will call for LoadConfigForAvailable Devices. In that it queries For Primary device details , Get Monotor code, FInd Device. In FindDevice() it has to Verify with the DwDevices and get the device, the DwDevices value is getting as 0xCDCDCDCDC in hex and hence it is looping in that for loop and not terminating. Becuase of this looping the CPU usage is going high.

In function Init, the member variable m_device is updated at the end – so when FindDevice is called before that (Power Persistence), it keeps looping.

Fix:
Update m_device as soon as the Current available devices are available. This is in addition to existing updation.

Max brightness value is wrong after resuming from Sleep/Hibernation.

Power Conservation

Windows Vista*

Mobile Intel® 945 Express Chipset Family

Root Cause: 

OS needs to send DxgkDdiBlcSetBrightness call to driver to restore the brightness. This is not being done.
This is an OS issue and might need a WA in driver.

The DxgkDDI SKU flag was not enabled correctly at boot. This results in driver not taking over backlight control correctly in resume from S3 and S4 in Sony's backlight control usage model.

Corruption or little garbage is seen on objects of Microsoft DirectX SDK

Direct3D*

Windows Vista*

Intel® 965 Express Chipset Family

 

Root Cause:

 

Back to back draw calls were using 2 different vertex shaders. Both of the vertex shaders required scratch space but different sizes per thread. The driver didn't comprehend the different scratch space sizes per thread when allocating scratch space memory for the vertex shader unit so the same scratch space memory was assigned for both vertex shaders. When these 2 different vertex shader threads were running concurrently in the EU's, they both used the same scratch space memory with different size per thread requirements and hence the scratch space accesses per thread overlapped and corruption resulted.

Resolution is to include the per thread scratch space size in the scratch space cache key so GHAL3D will allocate a different scratch space memory allocation for shaders with different per thread scratch space size requirements.

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* .

It was just that this was not getting executed because every time when the CDS fails when setting position data , we used to return as success where it will update the registry and stop the process.

The fix is returning failure when CDS_TEST fails. This would allow CDS to apply right data after login, which is handled in WM_WTSSESSION_CHANGE.

LCD still secondary, no display or wrong resolution after DP hot unplugged when ext desktop w/DP primary, LCD secondary

Soft BIOS

Windows Vista*
Windows Vista*-64

Mobile Intel® 45 Series Chipset Family

Root Cause: 


When the display is getting unplugged, CUI will get the display change notification and ask SB to get the mode table. Since the display is not connected, the mode table that SB builds won’t have EDID modes. OS will again issue ISV call stating the previous configuration when the display was present. Since the last configuration involved an EDID mode which is not there in the mode table now, this call will fail and hence the issue.

This mode is actually present in SB static mode table, but was getting pruned out in RM due to BW checks. For that reason, we added RB timings for this mode in the static mode table and because of this, this mode won’t get pruned out by RM. As a result of this, SB mode table will continue having this mode even after display is unplugged.

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 skipped on the boot up, the initialization is redone after a GPU switch.

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 64-bit platform, there have two completely different HKEY_LOCAL_MACHINE\Software views for 32bit and 64bit. The ILDB registry key is written in 64-bit registry key view through inf file. A 32-bit application such as WinDVD invokes 32-bit driver model, which reads the registry keys from the 32-bit view, so it doesn’t see the correct path.

So on a 64bit system, we need to force to read 64bit registry key view in our driver 32bit dll

When PC starts 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.

Fix is to disable SDVO ports after ACTIVE_OUTPUTS_OFF opcode is sent.
