Root Cause: The alpha
palette was passed to the kernel in incorrect format. The palette format
was decided incorrectly based on the destination format instead of source
format. We were getting away with this until I added changes to do
scaling+blending in single call (DCN 631780) because the source and
destination format used to be the same for standalone blending case(Eg.
PL_BLENDING_PA, RGB_BLENDING_RGB). But now, we could be using a kernel like
PL_SCALING_BLENDING_RGB for blending and that makes the issue manifest.

Resolution Description:
Root Cause: This is for
implementing full overlay downscaling in Windows Vista*. The current driver
does not support downscaling more
than 2:1. That is, if the destination window's size is less than 1/2
the source window's size, then the current
driver clips the destination to 1/2 the source. In this DCN, we add
support so that the driver handles the
downscale request to less than 2:1. This blt is done by using the 3D
engine to do a bltfrom the original OS passed source to an intermediate
surface with the destination window size. Then this intermediate surface is
used to display the overlay.

Root Cause: Issue &
Rootcause: LFP is Dual channel but we are programming it as Single channel,
that’s why screen gets whitish. Now why
this occurs is because, in VBT there are two ways to mention whether
IntegratedLFP is Dual Channel & Single Channel. One way is to program
appropriate bits in LVDSPort register’s default value mentioned in VBT.
VBIOS updates it appropriately. Other way is to mention it in
“NoOfChannels” field which has value 0 (Automatic Selection) in this case,
which is wrong. Currently in code, we rely on NoOfChannels field only &
for Automatic Selection we will decide no. of channels based on Panel’s
resolution. As customer's LFP is 14x9 SB logic wrongly interprets Panel to
be as DualChannel. Fix: For Automatic Selection we will check the Port
Register bits to decide no. of channels the LFP has, which VBIOS updates
properly.

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.

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

w/in the node manager. Gaurds must be used to prevent corruption of nodes
and the node manager. Multiple threads could be accessing a single heap
simultaneously if the APIENTRY is reentrant. Gaurds must be put in for
those heaps. DCN also fixes independent rotation on BLB.

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.

|
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.

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.

Resolution Description:
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: Once TDR happens, driver does a Graphics Device
Reset with which all the MMIO and I/O register gets initialized to default
values. Due to which ActiveToggle list table index and GR18 I/O
registerwere also getting zeroed out as a result of which Display switch
was blocked.
Fix Description: So now once
a TDR happens we save the state of scratch registers before a graphics
reset and restore the relevant fields after the reset is done.

Resolution Description:
Root
Cause: When hot plug is enabled, it generates an interrupt
but driver does not receive this interrupt as interrupt is not enabled in
the GMCH by this time. As a result interrupt state is not cleared in the
encoder and consequently it blocks all future hot plug interrupts.
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.
