Resolution Description:
Root Cause: Two issues
fixed by this DCN. Issue (1): Root Cause: The problem is the detection of
first boot event. By looking at "FirstBootDone" in gfxinitialize,
if this key is NOT present, it becomes first boot and creates the key. On
subsequent boots, since this key is presented, it is NOT first boot.
Problem starting as the driver is
installed on a fresh OS. It is immidiately loaded, and a call to
GfxInitialize is made. Therefore we will read and set this key, and caused
the actual first boot after the driver install be considered as a
subsequent boot. Since we do not decicde the configuartion based on first
boot algorithm on a subsequent boot, issue happens.
Fix Description: Create the "FirstBootDone" Key only on a
display modeset. Since the driver load immediately, the installation does
not load the display driver. This key will not be created on an actual boot
after driver install but get created on the first display mode set.
Therefore we will be able to detect the first boot and subsequent boots properly.

Resolution Description:
Root Cause: Two issues
fixed by this DCN. Issue (2): Root Cause: When we detect the devices for
first boot algorithm, we are doing a passive detect, relying on the active
detect performed by GfxGetChildDescriptor which also does a Legacy CRT
detection. But before coming to first boot algorithm (GfxInitialize), we
also do a display detect without legacy CRT detection to get the encoder
list for building FSM in the event manager. The event manager removes the
CRT from the list if it is legacy, so the passive detect in boot algorithm
does not show CRT. Then we go to LFP SPSD thinking we have only one device.
Fix Description: Do an active detect for getting the connected devices
for first boot algorithm. To reduce the number of active detection calls,
do a passive detect in the same handler (Driver_Fresh_Install), which is OK
since this will always be preceeded by an active detect in the first boot
algorithm.

The previous condition was only check for the primary surface not in the

Fix Description: Add more conditions to check for the primary surface,
primary surface not in the front and at least one back buffer count. Since
the need to fix the other bug with this condition of 800x600 resoultion,
this resolution condition is also added to allow only 800x600.

Cause: 64-bit Windows* XP sending smaller size buffer appears

Fix Description: As per DDK, in the event of an error, DrvGetModes DDI

size when buffer for mode retrieval is less than the modes available.
Subsequently, OS requests for mode table by passing correct buffer size.

Resolution Description:
Root Cause: The VBT has multiple panel with same PnP ID value. All
the entries have same DTD timings. The VBTMANAGER_FillSimilarPnPId adds 4
of them into the LVDS timing structure. During the mode table building when
these modes are to be added, the preferred one gets overwritten with the
another one that has similar timings.
Fix Description: Not to add a panel’s detail in
VBTMANAGER_FillSimilarPnPId if the timings are same, since the PNP_ID
method is to support timings where the X and Y are same but different
refresh rate.

Root
Cause: This patch covers up a memory corruption to the
pixel shader constant in the indirect state buffer when there are no commands
pending and the scene has not be initialized. In this case, the synctag in
gfxFlushSB and gfxFlushNB are left as NULL, so old tag for the pixel shader
constant is used which may lead to free this resource prematurely. Setting
the synctag's default value to the lastSyncTag prevents the resource free
too soon; however, this is only a patch and does NOT fix the root cause of
this problem, which is to be determined.
Fix Description: Avoided NULL syncTag.

Cause: From 14.19 onwards, CUI queries Event Manager for
all valid configurations. All the
configurations in the machine array (created during boot time) are
validated using following criteria: Test 1) Configuration should be valid
according to SB, 2) Connectivity Check: A state is valid if all devices in
the configuration are connected otherwise state is invalid, and 3) Overlay
check: If overlay is running and display switching is blocked while overlay
is running, any state other than the current state is considered as
invalid.
Fix Description: Overlay running and display switch blocked with
overlay running is treated as a separate case. So in normal scenarios, only
Test#1 and Test #2 are performed to validate the configuration. Special
Case (Overlay running and display switching blocked with overlay running):
In this case, we do not need to iterate through the machine array (contains
all the valid states - build during boot time).

Resolution Description:
Root Cause: In ConfigPersist.cpp::GetCurrentConfig, EDS is called with ENUM_CURRENT_SETTINGS
and ENUM_REGISTRY_SETTINGS. If the modes returned are different,
ENUM_REGISTRY_SETTINGS data is taken as the current config.
In these scenarios, the panning mode is returned in ENUM_CURRENT_SETTINGS
and the actual mode (which is also stored in the persistence registry) is
returned in ENUM_REGISTRY_SETTINGS. So the persistence functions think the
current mode is the same as the mode that need to be applied from registry.
That’s why it does not run ApplyConfig. So SyncOSAndDriverThread is not started. So when login
happens, the event is not processed by persistence.
Fix
Description: While comparing the
configuration, current config is taken from CUI
Service method and config to apply is taken from
persistence method GetCurrentConfig. A new
function is introduced to verify if these two configs
are the same or not. Also the logic used in GetCurrentConfig
is modified to rectify the issues that are faced due to usage of EDS call
for Display2 in non-MDS case.

NULL SharedInfo pointer in GetRingBufferSpace

Intel(R) 915G Express Chipset

|
Resolution Description:
Root Cause: In GetRingBufferSpace
function, we update the PGhalFctTable structure
using the information from PDeviceSharedInfo. If PDeviceSharedInfo[1] (first device info) is Null then we use PDeviceSharedInfo[2] (second device info). But here we
are not checking whether PDeviceSharedInfo[2] is Null or and the issue is happening when both
device info are Null. The issue does not arise if sufficient care was taken
by checking the status of Pdev before calling the
lower functions like GetRingBufferSpace function.
This case does not arise in GDI as we will check for Pdev
status.
Fix Description: A Null check was introduced for the
secondary device info before updating the PGhalFctTable.
If this is also null then in the else case, we will return Null. This is to
ensure that the crash doesn’t happen in Ghal.
However corruption can happen as the calling function will get the Null
pointer. In all GDI functions, Pdev status will
be checked before passing down. This is not the case with DD or D3D
functions. Hence similar Null checks were introduced in all possible Ghal functions which can be called from DD or D3D
functions and where a Null SharedInfo pointer can
be accessed

Resolution Description:
Root Cause: SoftBios
internally uses the GMCH_CONFIG data which is supposed to be up-to-date. In
this case it receives a call to enable VGA on PipeB
due to which it internally disabled plane A & B. Now GMCH config will say PipeA has
NULL_PLANE and PipeB has VGA plane, but later it
receives a call to set new mode in pipeB. It does
not receive any call in PipeA to set last mode.
So the internal gmch config
data will be out of sync.
Fix Description: Softbios GAL
layer disables secondary plane as part of enabling VGA plane. This resulted
in a GDI WA where they used to forcefully enable secondary plane during
hires mode set on primary. A better fix would be to do this within Softbios GAL layer where it exactly knows that it
disabled secondary plane & hence should re-enable it when coming out of
VGA mode. Even with this, there will be a slight flicker on secondary since
plane transitions are occuring display plane->vga plane(blank
screen)->display plane. This flicker is the same as it occurs with
current code base.

Resolution Description:
Root Cause: When the adapter comes out of hibernation,
it again maps (temporarily) the GTT so that it points to contiguous pages
in the Stolen Memory. By writing the
pre-hibernate values to the GMADR it restores the contents of the Stolen
Memory. It also restores back the
pre-hibernate entries in the GTT Table. But at the time the driver is
called to come out of hibernate, the VBIOS has already put the adapter and
the child devices to PowerON state – so as to
display the POST screen. At this time the VBIOS is using the Stolen Memory
as the frame buffer. It also sets up displays in VGA Mode. The Displays are
enabled and hence restored Stolen Memory values are displayed onto the
screen –the display corruption.
Fix Description: The fix provided will turn off the display
data fetches and disable video output, before the stolen memory is
restored. Since the display devices are in VGA mode, the “VGA registers”
can be used to achieve this. The VGA’s sequencer register – ‘SR01 Clocking
Mode’ will be used to turn the Screen Off.

combination and leading to garbage on TV.
(In 14.18 code base (old SB), Softbios

configuration (LFP+CRT in case-1). So, now when the actual dock
notification comes through VALIDATE_CHILD_IOTCL, driver will notify CUI
about dock event and but since CUI persistence is already overwritten with
(LFP+CRT) in case-1 the display will go to wrong configuration i.e. LFP+CRT
in Extended Desktop.
Fix Description: We need a mechanism to handle dock/undock
event irrespective of the order in which SET_MODE call or
VALIDATE_CHILD_IOCTL is received. To do this we will notify CUI about the
dock event if it is found during SET_MODE call. The flowchart below
explains the mechanism in detail.

Resolution Description:
Root Cause: There is a pixel stall coming
from dpiounit which is being shut off when the
Port is turned OFF. Note that the Display Plane and Pipe are still turned
ON and the display fifo is being drainied in an accelerated fashion as the port is
turned OFF. This causes an underrun (real underrun) finally. And this happens even with FBC shut
off. But Display h/w has hooks to
recover, but the Decompressor does not recover if
FBC is turned.
Fix Description: Due to the underlined condition, this was
considered as a WA. So a WA flag (WaDisablePlaneForMonitorOff) was defined in
the WA table which will be set only for Calistoga. Issue is not validated/reported on Alviso
& hence WA will not be enabled on platforms other than Calistoga. If
this WA flag is set, SetPortPowerState() interface of GMCH will be overloaded by GMCHNAPA_SetPortPowerState(). This method in addition
to inform port controller of power state change (default implementation) will
turn off display planes assigned to the pipe driving the input port, ulPort. This will be done iff
there are no enabled ports on the pipe. If there is one, then we don’t need
this WA as per the statement above. Similarly on monitor turn on, it will
enable planes as required.

Intel(R) 945GM Express Chipset
|
|
Resolution Description:
Root Cause: The issue happens because GDI
returns only 800 x 600 resolution in DrvGetmodes call from OS. Since we have rotation
disabled in INF, OS calls DrvGetmodes with buffer
that can accommodate only non-rotated modes. In DrvGetmodes
fn while checking for whether rotation is enabled, we have rotation enabled
in registry. So GDI reduces the buffer size four times inside DrvGetmodes.
The
Display1_EnableRotation registry key is enabled temporarily by CUI during
the resolution change in the function PersistRotationEnabledStatus(). Whenever CUI wants to get the current rotation
angle, it enables rotation temporarily. Within that period if GDI looks at
the registry, it find rotation enabled.
Fix Description: While checking current rotation angle, if
the rotation capabilities is 0, do not check for
current rotation angle and send the default value, which is Rotation_0
degree.

PC
|
Intel(R) 915GM Express Chipset
|

Resolution Description:
Root Cause: After a suspend resume operation
in extended desktop mode, when we try to go to single display, DisableSurface() call does not come . The expected call sequence in
this case is DrvAssertMode false and DisableSurface() for secondary. This is a tablet PC OS issue, so
driver does not come out of extended desktop and switch does not happen.
Two problems here: 1)
We do not see the complete menu for toggle sequence on
pressing Fn + F7, because scratch bit is not set. Scratch bit is used to
inform SoftBios and Bios about the SD and ED
modes that are responsible for displaying the options for Fn + F7. The
scratch bit is set in DrvDisableSurface(). But since DrvDisableSurface
does not come, the scratch bit is not cleared. 2) If we somehow set the scratchbit in Assertmode(false) call, the
complete menu of ACPI devices is displayed with the DDC option, but
miniport does not allow the switch as registry is still MDS.
Fix Description: Since this is an OS issue, the following
are only workarounds. 1) Made changes in DeAssertMode() function
and inform Softbios about mode change by clearing
scratch bit in DrvAssertMode(false). 2) Made
changes to EM_ACPI_HOTKEY_handler. The AttachToDesktop Key is properly set by OS to indicate
single display mode. Here OS thinks that it is out of extended desktop, but
driver registry is not updated. The fix is if the AttachToDesktop
is 0 (SD) and driver’s config shows ED, then the
current configuration is set to SD. This is done in ACPI handler.

Resolution Description:
Root Cause: EDID has 780x576@50Hz as the
largest mode and while removing modes with Unsupported RR, none of the modes
match this RR and hence were getting removed. So no modes get shown with
hide mode unchecked. Check for largest mode at same RR fixes this. For hide
mode checked as OS prunes all modes less than 800x600, no modes are shown.
This issue with OS pruning with hide mode checked is a universal problem
and hence no fix is provided in this case.
Fix Description: Code Changes: 1) Added a new parameter –
BOOLEAN bCheckRR - to the MODETABLE_GetLargestEDIDModeEntry
method to get the Largest Mode at the same RR. 2) Added a new parameter –
BOOLEAN bSameRR – to the MODESMANAGER_GetBestTimingAsInEDID
method to get the best timing for given mode at the same RR. The MODETABLE_GetLargestEDIDModeEntry is called with bCheckRR as TRUE if bSameRR
is TRUE. If bSameRR is FALSE or MODETABLE_GetLargestEDIDModeEntry returns no mode at
same RR, get the largestMode at any RR. 3)
Modified the signature of MODETABLE_GetLargestEDIDModeEntry

the entire call if any of the line (in multiple paths) view port is greater
than 2048. If we draw some paths using the hardware and then if we punt the
call because of the above reason, OS will redraw from the first path
onwards above the paths drawn by the hardware. Now if we move the figure,
while erasing the paths, the previously half drawn paths by the hardware will
be shown on the screen according to the mix values and becoming the
garbage.
Fix Description: Do not punt the entire stroke path if we
already had drawn some lines in the paths using hardware. Instead, just
draw that particular line (whose view port is greater than 2048) by calling
EngLineTo function. This will avoid the redrawing
of the paths by OS which were already drawn by the hardware.

Windows* XP

945GM EXPRESS CHIPSET
|
|
Resolution Description:
Root Cause: 1) Wait for Vblank
times out a number of times during resume from S3. Wait for Vblank called from various functions in GAL, more often
for register update and during pipe disable. However, this wait is not
required when VGA plane is enabled, since double-buffering is bypassed if
VGA native is enabled, allowing pipe to shut-off immediately. 2) Wait for
pipe disable timeouts during resume from S3. Wait for pipe disable is
called after pipe disable, where we need to wait for the vertical counter
to stop to ensure pipe is completely turned-off. There has been a bit of
uncertainty as to the right logic to ensure pipe is completely turned off.
The current logic looks for the scanline counter
to be equal to VblankStart. But it has been
observed that this wait times out sometimes and scanline
counter values are not incrementing to reach VblankStart
after pipe is disabled. A much better approach is to check whether scanline counter values are incrementing after each
horizontal refresh time (maximum horizontal refresh time possible) and wait
until it stops. Implementation of this logic has not resulted in any
timeouts and also an improvement in resume time.
Fix Description: 1) Added the check to return TRUE if VGA
plane is enabled on pipe, before waiting for Vblank
in NAPAPIPE_WaitForVBlank. 2) Added the check to
bypass wait for pipe disable if VGA plane is enabled on pipe, after pipe is
disabled in NAPAPIPE_Disable. 3) Modified the NAPAPIPE_WaitForPipeDisable function to implement the
new logic.

when we do a fresh boot.

Resolution Description:
Root Cause: The LFP EDID has 1024x768@60Hz
bit set in established timing. The DTD supports 10x7 @50 and 40 Hz. The
expected behavior is to have only DTD timings being displayed. Hence
anything in EDID other that DTD should not be considered as timing
supported for LFP.
Fix Description: 1) Added INTLVDSENCODER_IsTimingSupported to prune modes not
supported in DTD. 2) In MODESMANAGER_BuildPrunedCloneModeTable,
we added check for ModeListNorPrimary also, else
if display 1 supports 60 Hz only and display2 supports 50 Hz only then the
number of modes on clone mode list added were null.

Resolution Description:
Root Cause: In Clone, when the HDTV is on
secondary and in primary if we change a mode MainDlg::ClonePagesValueSwapper()
function is called and there if the current mode supports the existing format,
we should not do a format switch.
Fix Description: If the current
format supports the selected mode then we retain the same format in MainDlg::ClonePagesValueSwapper(() function.
