4563642

Garbage can be seen when entering the OS

Miniport

Windows* 7-64

3rd generation Intel® Core™ Processor Family

Root Cause/Resolution:

During the call to return to D0 and the call to Start the Device the WDDM 1.2 driver has to set the source visibility to false for all active VidPn targets this means the pixel pipeline is guaranteed to be sending black pixels to the monitor. This ensures that any modifications to the scan out surface are not visible on the monitor.

4565970,

After entering S3 on AC mode and resuming system on DC mode the panel color can become pale with DPST enabled

Power Conservation

Windows* 7
Windows* 7-64

3rd generation Intel® Core™ Processor Family

Root Cause/Resolution:

This was determined to be a race condition between algorithms entered on a power source change and triggered upon entering the OS causing a conflict with results due to DPST not being enabled. To resolve this the setting of DPST active flag was moved before enabling the DPST histogram interrupts.

In a TriClone mode with WiDi corruption on display while any window is dragged in the center of the screen from top to bottom part of screen

NT - miniport

Windows* 7-64

3rd generation Intel® Core™ Processor Family

Root Cause/Resolution:  

Due to low refresh rate of TPV the VBI for TPV was reported along with the VBI of IGD display. With 3 display clone the VBI for TPV was reported along with VBI of Secondary and Third IGD display. This results in reporting 2X VBIs and the flicker was seen on IGD. As a fix we wait for VBI to happen on all the IGDs and then report the VBI for TPV.

Bug ID: 4564435

Media Profile not persisting to current setting when switch CUI from Basic to Advanced

CUI

Windows* 7-64

3rd generation Intel® Core™ Processor Family

Incorrect refresh rate shwon when an external HDMI monitor is connected

NT - miniport

Windows* 7
Windows* 7-64

3rd generation Intel® Core™ Processor Family

Root Cause/Resolution:  

During Advise we used to advise the first mode in the target mode list.  In case of multiple RR's this advising was failing as the first mode might not be the optimal mode in the target modelist.

To fix this a new logic scheme was implemented to advise the native RR when present in target modelist

Bug ID: 4563900

During BD playback WiDi freezes when moving the playback window between WiDi and non-widi display

Media Codec (Encode)

Windows* 7

3rd generation Intel® Core™ Processor Family

Root Cause/Resolution:  

In extended desktop with an HDMI display and a Widi display there was a sporadic freeze when moving a playback window between displays. When the apps move from the wired display the HDCP session was de-activated by WiDi because they no longer require it. However since we keep a displayable PAVP session alive for Widi encoding this causes an auto teardown that kills it.

The fix keeps HDCP on for the wired monitor while any PAVP session is in play.

Bug ID: 4564243

Corruption seen on playing the "Tales of Lagoona" game

Direct3D*

Windows* 7-64

3rd generation Intel® Core™ Processor Family

Root Cause/Resolution:  

Corruption occurs due to multiple map discards being applied to the same resource and the vertex buffer heap not handling the map discards correctly. The heap implementation checks only for the last entry in the heap being busy. If it is not busy discards the whole heap when IncreaseHeapSize() is called.

Resolution: The fix checks for any entry in the heap being busy. If any entry is busy then ExecDeallocCb()(discard heap) is not executed and is deferred till the resource is locked in the next CommandBuffer.

Bug ID: 4564349

OpenCL enabled Applications could crash when PCIe Gfx card is installed

OCL Runtime

Windows* 7-64

3rd generation Intel® Core™ Processor Family

Root Cause/Resolution:  

The root cause is because the common runtime enumerates the underlying devices (CPU and GPU) during initialization and stores this information. However since the intel GPU device is disabled it is not enumerated. This is because we were trying to do a delete on a memory which is not allocated in the first place. The fix was to make sure that the pointer is set to NULL if there is no enumeration during initialization. Additional Checks added during the OCL Device driver shutdown sequence and the delete will be done only if the pointer is not NULL.

During BD playback WiDi freezes when moving the playback window between WiDi and non-WiDi display

Media Codec (Encode)

Windows* 7

3rd generation Intel® Core™ Processor Family

Root Cause/Resolution:  

In extended desktop with an HDMI display and a Widi display, there was a sporadic freeze when moving a playback window between displays. When the apps move from the wired display, the HDCP session was de-activated by WiDi because they no longer require it. However, since we keep a displayable PAVP session alive for Widi encoding this causes an auto teardown that kills it.

The fix keeps HDCP on for the wired monitor while any PAVP session is in play.

During the state validation the driver attempts to set up the NULL shader which results in NULL-pointer dereference and the application crashes. The way the driver is working around this to resolve the Crash is to add a if() clause protecting against NULL-pointer dereference. This only resolves the Crash case

BSOD 0x124 can occur when disabling and enabling the graphics driver during S3D movie playback on S3D eDP / S3HDMI (Blanks out on S3DHDMI and S3D eDP)

NT - miniport

Windows* 7 Windows* 7-64

3rd generation Intel® Core™ Processor Family
2nd generation Intel® Core™ Processor Family

Root Cause/Resolution:  

Gmm gets incorrect targetid of 0 and sends it as 0 only for query call during overlay creation.

Earlier GMM was querying per target ID. It resulted in wrong values being returned and tall buffer not getting created when intention was to enable S3D on secondary.

The fix is to query for s3d being enabled not per target id but for the entire system and GMM will create tall buffer based on that.

Note that since GMM is sending correct values for querying during enable S3D related call so all those parameters are correctly updated.

WMV clip shows green corruption during playback

Media Codec (Decode)

Windows* 7 Windows* 7-64

3rd generation Intel® Core™ Processor Family

Root Cause/Resolution:  

When using WMP to play a 1280x720 VC1 clip The decoding resulted is stored in a temporary DecodeRT with larger height (720+32) but in setting PMFX_SURFACE_STATE_CMD_G7 command the offset of YTILE_H_ALIGNMENT(32) is missed. So it would cause the UV plane data corrupt at the end of decoding for second filed.

Resolution:

Add the offset of YTILE_H_ALIGNMENT to YOffsetForUCb can resolve this issue completely.

When running the Futuremark 3DMark 06 Benchmark while in TriDisplay mode flicker can be seen

KMD Render

Windows* 7

3rd generation Intel® Core™ Processor Family

Root Cause:  

The number of display pipes changed from SNB to IVB (3 pipe displays). In SNB, when eDP panel itself is connected, the display was seeing the eDP panel in the Sprite plane. But in IVB, since 3 displays are supported eDP panel itself is going through Display Plane C. Thus, when eDP panel itself is connected, during any Present Flip operations, display was flipping into the wrong plane (sprite) instead of Plane C.

Fix: Changed programming to instruct Display HW to flip to Plane C during Present Flip operation when eDP panel itself is selected.
