Analog display becomes Default monitor if bitbashing bit is enabled in
inf file. |
SoftBIOS |
Windows*
7 |
Intel® Atom™ N400 Series |
||||||||||||||
|
Root Cause: When we set
"BitBashingSupport" to 1 in inf and install gfx driver, then this shows that Bit Bashing is used
instead of GMBUS to read monitor EDID which is a bug. Fix: This issue has
been fixed in SoftBIOS component of the driver. |

playback in Full-screen mode and VMR9 renderless mode is not smooth (Win7
& non-Aero). |
SoftBIOS |
Windows* 7 |
Intel® Atom™ N400 Series |
||||||||||||||
|
Root Cause: In non- Aero mode,
vSync was not getting generated correctly. Fix: The
issue was fixed by returning scan line counter value even in vblank period
for non-Aero mode. |

Momentary corruption seen over the top edge of screen
when booting to Win7 OS |
GMM |
Windows* 7 |
Intel® Atom™ N400 Series |
||||||||||||||
|
Root Cause: At
time of boot, high resolution plane is being tried to load. There is overlap with
initial physical pages backing high resolution FB and virtual address
pointing to physical pages of internal segments allocated during this
transition period and hence corruption is seen. Fix: To
avoid this overlap at initial transition period at the boot time, the pipe
and port is turned of and later on turned on or reinitialized when it is
needed, which will in turn minimize the visibility of corruption. |

with igfxsrvc.exe program, the memory usage increases and halt the system |
CUISDK |
Windows* 7 |
Intel® Atom™ N400 Series |
||||||||||||||
|
Root Cause: Memory was getting
allocated in the component and was not getting released. Hence the memory usage kept increasing when
ever it the function got called. Fix: So in CUI SDK, the function
was corrected to release memory appropriately during the invoking of the
function. |

GMM |
Windows* 7 |
Intel® Atom™

The "Maintain
Aspect Ratio" is no function on Win 7 |
NT-Miniport |
Windows* 7 |
Intel® Atom™
N400 Series |
||||||||||||||
|
Root Cause: When we select maintain
aspect scaling, then driver is properly giving the scaling option and also CUI
is sending right scaling option to OS to set display settings. But OS is not
giving a commit call. OS is driving Maintain aspect scaling and is thinking
there is no change in settings and so not driving the change display
settings. Fix: PNV graphics driver for
Win7 is WDDM 1.0 architecture, so driver doesn’t understands MAR [OS
limitation due to lack of CCD support], so a workaround has been implemented
in the driver which fixes this issue. |

SG interface exposed on
Pineview |
NT-Miniport |
Windows* 7 |
Intel® Atom™
D400 and D500 Series |
||||||||||||||
|
Root Cause: Switchable Graphics
interfaces are exposed with PineView branch drivers. Switchable Graphics is
not supported on PNV, so interfaces need to be removed or hidden. Fix: SG support has been
removed from NT-miniport component which fixes this issue. |

Black screen may occur during VGA hot plug with certain

Driver and VBIOS |
Windows* 7 |
Intel® Atom™ D400 and D500 Series |
||||||||||||||
|
Root Cause: Issue occurs when not all channels of R,G and B are terminated properly
on the monitor or there is a loose connection, the system reacts to it by
displaying black image. This has been root caused as a bug in both VBIOS as
well as the graphics driver. For more details, please refer to doc :
“GMA3150__Black_Screen_Alert_WW43.pdf” Fix: This issue has been fixed in the driver and the VBIOS. For the problem to
be completely solved, upgrading of driver as well as VBIOS is required. |

The brightness is still 19 levels on Win7 driver |
Power Conservation |
Windows* 7 |
Intel® Atom™ N400 Series |
||||||||||||||
|
Root Cause: Win7 recommends a minimum of 25 backlight brightness levels. OpRegion
BCLM was not extrapolating between the next lower level and higher level for
25 levels. Fix: In BCLM table of Power Conservation component , new brightness duty cycle
values were generated that fixes this issue. |

Win7 OS |
VBIOS |
Windows* 7 |

Not able to apply 656* 496 resolution in DDC mode WIN 7 |
SoftBIOS |
Windows* 7 |
Intel® Atom™ D400 and D500 Series |
||||||||||||||
|
Root Cause: This is because with latest Win7 build (7600) OS is pruning this mode.
Driver is adding this mode in CRT modelist and reporting to OS. But once it is
applied, OS does not allow it to set this mode. Fix: CUI was modified to be in sync when Hide Mode box is checked. |

WIN7 using CUI |
NT-Miniport |
Windows* 7 |
Intel® Atom™ D400 and D500 Series |
||||||||||||||
|
Root Cause: In the driver, we have a check for Native resolution of the
panel (Mode in EDID), which causes this function call to fail for to-be
downscaled modes. Fix: Whenever call comes for modes greater than Native, driver
will handle it appropriately if Downscaler is enabled. |

Left-shifted display on secondary monitor |
SoftBIOS |
Windows* 7 |
Intel® Atom™ D400 and D500 Series |

Root Cause: CRT display clock was not
being programmed as per the PLL sheet for modes less than 1280x1024. Fix: Driver code has been updated,
so that CRT display clock is in unison with DPLL Clock Sheet. |

KMD Render |
Windows* 7 |
Intel® Atom™ D400 and D500 Series |
||||||||||||||
|
Root Cause: When Independent rotation is enabled and when executing the
MMIO flip function where-in the function to save and restore floating point
state is called, this issue occurs. Fix: A workaround has been implemented to avoid this call, and
this fixes the issue. |

TV/ CRT static feature (forced detection) removal from

Windows* 7 |
Intel® Atom™ D400 and D500 Series |
||||||||||||||
|
Requirement: The option to force detect CRT/ TV is provided by the OS on
Windows7. This feature was provided by the Gfx driver on earlier OS - Vista,
XP. Since it is provided by the Win7 OS now, it negates the requirement for
the driver to provide the same and has been removed. |
