Windows Vista*
|
Intel® G965 Express Chipse
|
|
Resolution Description:
Root Cause: In some cases overlay flip calls are not properly
synched, so there are instances where one flip will overwrite a previous
flip that has not completed. This created visible frame drops and
jerkiness. Added code to wait for
MMIO flips information to be loaded before overwriting with a new flip.
This eliminates frame drops caused by the synching issue and improves
visible performance.

Resolution Description:
Root Cause: The issue
happens because the cursor buffer gets update before it came into effect by
changing the cursor registers (will take effect in next VBLANK). So, there
is mismatch between cursor buffer data and cursor registers type. This
results into corruption for a brief moment. The solution is to write new
cursor data into extra cursor memory and then use the extra memory address
to enable the different type of cursor. Since, in Windows Vista* there are
two cursor buffers are initialized for achieving the independent rotation. So,
we use the second buffer when there is change in the type of cursor and
after cursor data is written into new buffer, we update the cursor address
register to jump to the new buffer. Changed the total cursor memory buffer
allocation to get memory for 4 cursor buffers in GMM. 2 extra buffers for
Independent rotation case and extended desktop.

Resolution Description:
Root Cause: This issue is
happening because we are failing RFVN call while applying clone
configuration CRT+TV for 20 x 15 mode. Note that in this case TV supports only
up to 10X7 and the CRT has no EDID. While trying toapplying 20X15 on it we
fail to find native mode index for TV (which supports only up to 10x7).
Here we are getting the entire mode list because of existing clone mode
pruning logic in SB which is as follows: 1) If both the devices have EDID,Prune the mode list
based on the max resolution of least capable device (i.e. remove all the
resolutions beyond this). 2) Else return the whole mode list (upto20X15).
This logic was OK for Windows* XP which support panning, but it is creating
problem for Windows Vista* which doesn’t support panning. As a solution I
have changed this behavior by using a flag which will be set by Windows
Vista* MP. This flag will indicate to SB that it has to return the pruned
clone mode list even in the case of EDID less device (i.e. enabling the
step 1 for EDID less device as well for Windows Vista*). This will result
in getting the mode list only up to 10X7 in this case and user will not be
in a position to apply a mode which is not supported by TV.

Resolution Description:
Root Cause: 1) Windows Vista* for Extended Desktop the
first call can be either primary/secondary. Swapping of plane/pipe is not
happening due to current checks. Current swapping logic of DPDD is same as
DPSM. Swapping logic needs to be changed to be independent of call sequence
and should depend on the previous plane-pipe configuration and new
plane-pipe configuration. Swap should be done properly if any change in
pipe/plane assignments to the display device. 2) Bandwidth Issues where seen in case of
pipe swap. And also Due to pipe-swap GRM is getting notified and release
device is called in between commit path due to swap handler. Thus releasing
the wrong plane. And CRT blanks out. 3) Reworked on DPDD code flow. Made
code changes and added proper checks where ever required. Done changes in
Miniport/Grm.

Resolution Description:
Root
Cause: DVI-I hotplug is not handled properly in Softbios.
If there is an interrupt at SDVO port, Softbios selects the first encoder
object from the encoder list which matches with that port. But in DVI-I
case, both TMDS and RGB can be at the same port. This results in wrong
encoder object selection. Consequently, interrupt is not cleared properly.
Fix Description: Clear interrupts for all encoder objects correspoding

Functional Failure / Power Cons - ForceTDR app causes CRT
to exit Power Savings mode but no image is displayed.
|
SoftBIOS
|
Windows Vista*, Windows Vista*-64
|
Intel® GM965 Express Chipset
|
|
Resolution Description:
Root Cause: This issue
happens when we have LFP and CRT connected with the system with
configuration set as LFP only and we force the TDR (with the help of an
App), Monitor sync turns on and it sows some horizontal lines
intermittently. This is happening because TDR causes Port registers values
to get all 0s which has following effects for analog port. As the LFP is
also associated with Pipe 0 (Gen-4 system), as soon as we enable pipe 0
after TDR, sync starts coming on CRT causing undesirable behavior. As a
solution for this I have added a TDRHandler function in port controller
which will disable all the ports. This function will get called by SB TDR
handler after Graphics Device gets reset.

Resolution Description:
Root
Cause: For Intel® 945GM Express Chipset and beyond, the
FBC feature no longer needs to be notified about OpenGL applications
running. The flipping restrictions no longer apply after Intel® 915GM
Express Chipset. So, the testing needs to be modified for Intel® 945GM
Express Chipset and beyond. We will need to fix the code for Intel® 915GM
Express Chipset, though, so that OpenGL will properly get disabled in this
scenario.
Fix Description: 1) Platforms before Intel® 945GM Express Chipset do
not support FBC running with ANY kind of flipping. Therefore, checking is done on pre-Intel®
945GM Express Chipset platforms for Direct3D* and OpenGL being active, and,
if they are, disable FBC. 2) Platforms before Intel® GM965 Express Chipset
support synchronous flipping, but not asynchronous flipping. So, on
platforms before Intel® GM965 Express Chipset, we check for asynchronous
flipping from both Direct3D* and OpenGL. If it is occurring, then turn off
FBC. 3) Cleaned up the genearl Display Driver and GHAL areas where event
notifications to Power Conservation are generated.

Resolution Description:
Root
Cause: This issue has two parts. First is when 10x6 mode is
applied on LFP + SDVO_VGA DDC config (with FULL_SCREEN), the display on CRT
comes cornered to upper left. This happens as the ModesManager_CenterImage
is not called for FULL_SCREEN. Second part is after S3-resume in this
configuration, display on CRT comes stretched abnormally. This is because
of the CRT display being cornered to upper left part and stretching gets
removed if the VGA centering (BIT25|24 in 0x71400) is enabled. This
stretching also happens if there is upper-left cornered display on Int_LVDS
or DFP in LFP+DFP DDC config on CRL, and here also stretching vanishes as
soon as VGA centering is set. So, this upper-left cornered display in
FULL_SCREEN causes the issue.
Fix Description: For FULL SCREEN as well on SDVO VGA,
MODESMANAGER_CenterImage will get called.

Root Cause: Whenever
system boots/reboots, following was the sequence: We initialize the
DispDev->bConnected for all the displays to FALSE during StartDevice
Routine. OS does DxgkDDIQueryChildStatus for each of the displays. Here we
do a Static Detection of all the displays for the OpRegion and find that
the attached status of the displays and in DispDev does not match. Here we
update OS using CbIndicateChildStatus for all the displays where the status
does not match. In GfxUpdateDriverChildInfoPrivateData, we used to get the
bPreDetectionConnected status wrongly and hence TV Standard Change used to
happen resulting sometimes in TV Not getting detected.

extended desktop as we could in Graphics driver on Windows* XP. As part of
fixing the issue, we have tried to keep the behavior Windows* XP parity
w.r.t two VBT bits. One is Hotkey persistence and another is enabling
MDS/Clone on Hotkey event. With these changes, to exit out of EDS on an
ACPI Hotkey, Hotkey persistence has to be ON while to enter into EDS with
ACPI Hotkey both Hotkey persistence and enabling MDS/Clone on Hotkey event
should be set. This is basically the behavior we see in Windows* XP.

The Primary and secondary Displays blank out on resume

Intel® 945GM Express Chipset

Resolution Description:
Root Cause: The Primary
and Secondary Displays blank out on resume from hibernation for EDS
CRT+HDTV. It is actually not a blackout on both Primary and Secondary, but
a blackout on Primary only. Secondary blacking out (or empty screen ) with
password enabled during resume is an expected behavior. The issue is
happening because of a bug in the code, by which the source address is not
reprogrammed to proper values after a pipe/plane swap. Due to multiple
SetSourceAddress calls that OS sends in normal mode sets, the issue was
getting hidden in most of the cases. On resume from hibernation, with
password screen enabled, since we do not get subsequent SetSourceAddress
calls the issue got exposed.
Fix Description: If GRM recommended a Pipe/Plane swap, program the
source address properly. This would be done only if there is a change in
the planes being used, and will be ignored if GRM recommended a pipe/plane
swap, but the planes have not been swapped. ULT Details: Since these
changes would only affect Pipe/Plane swap, tested MDS with CRT+HDTV where
GRM would recommend a swap. Tested mode sets, S3/S4 resume under the same
config.

Root Cause: During Post,
VBIOS uses High Res Plane to display OEM Logo’s. This data in the frame
buffer is not cleared and hence the corruption. SB do not program Start
Address as part of setmode. There are cases that Start Address is not
available during setmode in Windows Vista*. Windows Vista* OS will call
Driver to BlankVideo before setmode and enables back the video after
setmode through SetSourceVisibilty DDI. But SB internally disables and
enables back the video as part of setmode. This causes the corruption. This
was required for Windows* XP to synchronize with render. The same is not
required in Windows Vista*.
Fix Description: Added a new flag bVideoBlankingReqd in setmode
interface. Clients have to set/reset this flag based on their need.
Windows* XP setmode path has to set this flag and Windows Vista* setmode
path has to reset this flag. We need to set this flag in all cases within
SB where we use SetMode Interface.

Root Cause: One issue was caused because OpRegion
memory was updated of connected devices wrongly with LFP as connected even when
lid was closed. The other issue was happening because OpRegion
implementation of driver was not taking care of Display configuration
removal Table.
Fix Description: The fix was to tweak the
function GfxGetAttachedDisplayList function in such a way that if OpRegion
update flag is set, then the device list gets updated. Adding devices for
CUI Static, Hotkey Static and LFP detection are handled have a new function
which will again make passive detection call but without ENABLE_REPORT_LFP
flag set. The above will be done during enumeration itself. While
discussing this issue, we thought of another issue where in with CUI static
bit set, during detection in boot, we will not report disconnected devices
and the same will be updated in OpRegion memory. However, when the system
comes up, we would want to have OpRegion memory updated with CUI static
devices of CRT and TV updated. So, we update OpRegion memory with Static
device and Hotkey device flag set across any events.
The
fix was also to check during the determination of next configuration to be
set from the toggle list, whether it is valid or not by using Event manager
interfaces

Cause: When hot plug is enabled, it generates an interrupt
but driver does not receive this interrupt as interrupt is not enabled in

Fix Description: Fixed the
issue by putting a workaround in UAIMEH. Added a new function
UAIM_HotPlugInterruptClearWA() in UAIMEHDFP.c, which gets called after
enabling hotplug. In this function, it is verified to see if there is any
hotplug interrupt source at the output corresponding to the pAIMObj. If
there is an interrupt event at that output, interrupt state is cleared.
