Ironlake

 

Root Cause:

When two consecutive draw calls use different drawing rectangles (viewports) from which the second one is smaller, in certain scenarios the clipper viewports buffer is not being updated in memory, so that the second drawcall uses a guardband that is too large. This results in accepting too large geometry and leads to quantization errors at clipper.

Bug ID: 3358246

Can't broadcast from HDMI even set HDMI audio as default by manual when switch monitor.

Soft BIOS

Windows* 7
Windows* 7-64

Arrandale

 

Root Cause:

When we change config from LFP + HDMI EXTD to SD HDMI, OS issues two modeset calls with SD call first for LFP and then SD call for HDMI. During the first mode set call, since HMDI is not a valid display in future config we are re-setting the PD bit. This causes audio driver to remove the audio end point and application starts using internal speakers as enumerated by OS as default audio device.

When SD for HDMI happens, audio driver indicates back to OS that HDMI end point is enabled but application still continues to use internal speakers as default speakers causing the bug.

Fix:

Miniport will schedule a timer DPC on the first mode set which when expires will verify if HDMI is there in end display config or not. If its not , miniport will make call to softbios to reset PD bit and HDMI audio end point will be removed. So we don’t reset PD bit in the first mode set and app continues to use the HDMI audio end point as default device. Same logic applies for DP displays also.

If the any display device( CRT/panel/DP) attached in primary, it works fine.

However, driver doesn’t prepared for new WiDi display device to attached primary device.

So, it caused program wrong display plane and ring buffer failure.

This problem occurs because Monitor-Control Function delegate is called every time when we go to Multiple Displays page (which should not happen it should be executed only once).

Fix:
Removing the delegate when it gets called for the first time.

·       When customer does fast copy from 1920x1080 to whatever target size( equal as or smaller than source size) AddressUV always starts from "AddressY + 1088*Stride" then you could copy the whole or part of UV data.

Root Cause:

The frequent resizing of windows is causing the memory usage to go up abruptly thus causing the DWM to become unresponsive.

The clone mode can not be set via Display Switch Tool

Root Cause:

19*10 is native mode of LFP, but  beyond CRT’s Dot clock limits so we prune it out in CRT’s monitor mode list. However CRT has 19*12 as EDID mode.
The fix is to center 19*10 to 19*12 in CRT.  Modes outside Dot Clock limitations have been removed from mode table, only for CRT and only in 15.17. Driver will itself go report the next higher target timing when it fails to find this mode in the mode table.

Test fail in Lullaby test on DTM 1.4

Soft BIOS

Windows* 7
Windows* 7-64

Mobile Intel® 4 Series Chipset Family

Root Cause:

Failing case has DVI and HDMI encoders enumerated. During S3/S4 resume, we set CP_ready during DVI detection. This triggers unsolicited response(UR) in audio. By this time graphics driver has neither populated ELD buffer nor configured PD/ELDV bits. On receiving the UR, audio driver enumerates audio device with ELD set by VBIOS or destroys audio device if there is no ELD data. Also for HDMI we were setting CP_Ready and actually programming ELD in settiming. So for a short duration, CP_Ready=1 but ELD buffer is not valid. These two scenarios result in Lullaby failure or WHQL failure.
Fix is not to set CP_Ready until end of settiming in graphics driver.

The fix is to set the usage of the render target resource to RESOURCE_USAGE_WRITE during bind time since at that point we know for sure that the resource is being written to.

Video jitters and frame drops when maximize/restore AP during playback of BD title

Soft BIOS

Windows* 7
Windows* 7-64

Arrandale

Root Cause:

1) Issue happens with application which creates overlay interface.
Issue doesn't happen with PowerDVD9_2202 which has no overlay interface.
2) Captured GPUView data. Blue vertical line is Vsync. Red vertical line is Present. When blue vertical line is overlapped with red vertical line, you see red color. Vsync is always regular, has no mistake.
3) When maximize/restore or scale window, driver calls kmupdateoverlay. There should be no or very few present during calling kmupdateoverlay. See attached PDVD_famedrop_1.jpg. You could see big present-absent area, that's expected.
4) After calling kmupdateoverlay is done, unexpected frame drop happens, that's issue. See attached PDVD_famedrop_2.jpg for frame drop. Frame drop happens because there are no packages from PowerDVD, see row " PowerDVD.exe Context CPU Queue" in the bottom.
5) Attach PowerDVD normal case PDVD_normal.jpg to compare with PDVD_famedrop_2.jpg

The issue is occurring whenever sprite window size is modified. This occurs as CRC calculations take ~340ms and they have to be done on each sprite size modifications. Fixed this issue by not enabling the ESFVP if sprite and display plane sizes don’t match.

Soft BIOS

Clarkdale

Root Cause:

The root cause is that VBIOS doesn’t enumerate some VBT fields for LVDS on DT, but driver would still look for it. Removed the parsing of such fields for desktop platforms.

SUT can not set max resolution (1440x900) on WXGA+ panel in clone mode with a 19x10 native external monitor

NT - miniport

Windows Vista*

Arrandale

Root Cause:

This issue was observed in a system with max LFP resolution 1440x900. In clone mode with a CRT having native 19x10, we were not able to apply 1440x900. The cause was that 16x12 was getting selected as the target timing and since 12 > 10 (native Y) IsSupportedVidPn was failing.
Resolution: Prune target modes where Y > (native Y) for CRT.

Video BIOS

Windows* 7-64

Mobile Intel® 4 Series Chipset Family

Root Cause:

DPLL registers were getting locked and could not be programmed to new values during a display switch. Cleaned the code such that write protection is enabled / disabled only once in the entire sequence. Panel power off sequencing does not lock the registers after switching the panel power off. Panel on sequence turns power on for LFP and locks the already programmed DPLL registers.

WXGA+ panel with X19 (2014) VGA driver can't boot to OS.

Soft BIOS

Windows Vista*
Windows* 7

Arrandale

Root Cause:

Panel supports only 6bpc color depth. As part of port bw pruning for DP, we had an assumption of 24 bpp (i.e 8bpc).
The pixel clk for this panel is 101 Mhz, which cannot be supported on x1, HBR, 8bpc and hence it was getting pruned out.

Mouse pointer broken if set rotation and extended display.

NT - miniport

Windows* 7

Mobile Intel® 4 Series Chipset Family

Root Cause:


The system appears to be hung/frozen when changing configuration. This seems to be because of OS being too busy with mode enumeration. The enumeration here seems to be taking much longer than what it should have been for causing no hang sort of situation. The issue seems to happen with displays supporting more modes, therefore making the mode enumeration process lengthier.

Optimized the code to get Refresh rate faster.

Cannot display video while using D3D9Overlay on G45

KMD Render

Windows* 7

Mobile Intel® 4 Series Chipset Family

Root Cause:

This workaround is disabled the scaling when the system is G45(CTK, ELK) system and running D3D9Ovelay.
The problem is the change to RGB intermediate surfaces, so now that we are properly creating intermediate surfaces to match original surface we have an issue where OS is blocking our ability to create more surfaces because of the combination of Overlay Surface Address limitations and the OS limitations on Overlay surfaces taking a certain amount of space.

A part of WMC menu is not displayed when move the mouse cursor to right edge of desktop on 180 degree rotation.

NT - miniport

Windows* 7

Arrandale

Root Cause:

During rotation, while we rotate the cursor buffers, the rotated coordinates sometime go out of bounds of the actual hardware cursor buffer coords. Since we always need to program at least one active pixel of the buffer in order for the hardware to work properly we were adjusting the coords accordingly on Windows Vista*[ where we always knew the buffer size was 256x256]. But from Windows* 7 onwards this assumption no longer holds good, so now we adjust the coords based on the cursor buffer size dynamically.

Green line is displayed at bottom of playback area when play mpg file

DVD

Windows* 7

Clarkdale

Root Cause:

When HD Content is played, the Surface Height is 1088, but the SrcRect Height is 1080. The Deinterlacing algorithm reads outside the rectangle, so we see a green line and / or garbage at the bottom of the playback window.

The fix is to clamp the Surface Height to 1080 if SurfHeight == 1088 & & SrcRectHeight == 1080. We will not clamp the Surface Height in any other case.

Root Cause:

Issue is because VBIOS was not putting the eDP port to Link idle state before turning off the port. This cause F8/Os selection screens to blankout.
Also, in plane control register, VBIOS was not changing the tiled memory bit to linear. This caused the corruption when driver un-install.
