Control Panel Extension
-----------------------
A control panel extension is provided to configure certain parameters of
the driver like Compression and DDC. The details of these parameters are:
Registry Settings
The driver behavior depends upon the way is been configured. Below are
the registry settings that change the behavior of the driver.
Compression:
This option enables the driver to enable or disable compression. Lossless
graphics compression is a hardware feature of the Geode processor.
Display compression has three possible driver settings:
0 - Compression is always disabled. No video memory will ever be
allocated to hold the compression buffer.
1 - Compression is enabled by default. However, if the allocation
of video memory for the compression buffer causes a display mode
to require more memory than is available, compression is disabled.
2 - Compression is always enabled. If the allocation of video memory for
the compression buffer causes a mode to require more memory than is
available, that mode will not be available.
LinearFB:
This option configures the memory layout for the active display data.
The display compression hardware inside the Geode processor is most
efficient if the space allocated for a single line of display data is
equal to a power of two. When the size of each line is 1K, 2K, 4K, or 8K,
each line of the display is individually compressible. However, this leads
to wasted video memory. For applications that require efficient memory, or
for applications that flip the primary display (such as games), it is often
more beneficial to allocate only the amount of space needed for the active
display. There are three possible settings for the driver:
0 - The size of each display line is always a power of 2. If the amount of
memory needed for a display mode is larger than the available memory,
that mode is discarded.
1 - The size of each display line is a power of 2 by default. However, if
the amount of memory required by a display mode is larger than available
memory, that mode uses a linear frame buffer to fit the mode.
2 - The frame buffer is always linear. The display is compressible only as
a whole, leading to less efficient compression. However, all of video
memory is always be available.
AntialiasedText:
Many legacy applications and some parts of Windows use antialiased text
to render font data. Antialiased text is a 4 bpp alpha blend. Enabling
this feature enables a simplified version of antialiased text that runs
on the Geode hardware. As the algorithm is simplified, this feature should
be disabled to allow software rendering if a compatibility test is doing a
pixel-by-pixel compare that is failing.
DDCEnabled:
This option enables the driver to query the monitor for the best-supported
resolutions. This will be disabled automatically if a flat panel is detected.

RELEASE HISTORY
--------------------------------------------------------------------------------
Previous Version 1.03.05, General Release
Release Date: May 25, 2004
Dependencies
------------
- Windows XP Professional with Service Pack 1 or
Windows XP Embedded with Service Pack 1
- AMD Geode SP4GX22 XpressROM v1.30.02 (or later)
- Durango v2.57.00
Functional Changes
------------------
- Cosmetic changes to display applet.
- Removed all unused driver routines.
- Fixed pointer code when panning on a TFT with a software cursor.
- Disallowed devices surfaces with a width larger than 2K pixels.
- Updated display applet and .inf file for DDC (Display Data Channel) support.
- Non-TFT modes are now filtered when running on a TFT part.
- New display mode matrix. 60, 70, 72, 75, 85, 90 and 100 Hz for most modes.
- Fixed copy FOURCC functionality in DirectDraw for 4:2:0 surfaces.
- Updated DdCreateSurface to allow the creation and use of non-overlay FOURCC
surfaces.
- Added support for the DdGetAvailDriverMemory callback.
- Removed deprecated driver escapes originally intended to allow the driver to
be used as a hardware debug tool.
- Added size and header verification for all driver escapes.
- Fixed a driver bug causing the path object in DrvStrokePath not to get reset.
- Added VER_FILEVERSION definition to the resource file.
- Added support for gamma correcting the primary surface in 32 and 16 bpp modes.
- Fixed a memory leak seen when changing display modes.
- Updated the driver heap logic such that all driver surfaces are opaque. This
implementation is more robust during mode changes, when GDI juggles the surface
handles for driver surfaces.
- Updated the driver heap logic such that GDI surfaces ejected from video memory
by a DirectDraw allocation are still managed by the driver. This ensures that
the driver can always free the associated memory. It also allows the driver to
reinstate the bitmaps once DirectDraw exits.
- Added a simple semaphore around all drawing routines.
- Updated the DLL to punt accelerations during a mode change, as some surfaces may
be in video memory, but still be in the color depth of the old display mode.
Defects Corrected
-----------------
Issue #170.5: GuiJr Fonts GDI test fails on DCT with Geode SP4GX22 system platform.
The failure is occurring due to a mismatch in our antialiased text algorithm.
This is to be expected, as our algorithm is a very rough approximation
designed to improve system performance. The test can be made to pass by
disabling antialiased text support in the display applet or in the driver .inf.
In 1.02.01, an issue prevented antialiased text from being disabled properly.
Issue #170.3: DCT Win2001 GDI test bluescreens system.
The Geode GX processor driver was updated to remove all driver escapes targeted
at hardware debug. Additionally, the driver now checks the size and header of
incoming data packets.
Issue #118.440: Major Jitter on HSYNC when Geode GX processor is halted.
The PLL settings for the modes supported by the BIOS were extracted from the
BIOS tables and verified against the grail spreadsheet. The new display modes
use PLL settings generated with the latest redclk.exe
Issue #170.10: HCT refresh rate test failed on Geode SP4GX22 system platform.
Test now passes with the current driver.
Issue #170.11: MPEG2 file loses video with Media Player on Geode SP4GX22
system platform. The driver was exporting the DdSetColorKey routine, which
is ill-behaved. This routine is optional and was discovered to be best left
unimplemented.
Issue #118.287: WinXp Window Media Player hangs.
The fix is to change the miniport driver to only expect one pointer in its
routine to unmap memory.
Issue #118.467: CPG - PassMark Burn-In 3.2 - 2D graphics test failure.
This test was fixed by exporting information about the driver's DirectDraw heap.
Issue #170.8: DCT GUIMAN GDI w/rect clip (gmvideo9) test failed on Geode SP4GX22
system platform. This test passes with the 1.03.00 driver and the latest DCT
with the DX9 QFE.
Issue #170.9: DCT GUIMAN Win GDI (gmvideo3) test failed on Geode SP4GX22
system platform. This test passes with the 1.03.00 driver and the latest DCT
with the DX9 QFE.
Issue #170.12: Corruption after playing AVI file overnight on XP.
The release notes for the Geode GX processor's graphics driver v1.03.05 have
been updated to caution the user when using the 1280x1024 100 HZ mode.
Issue #170.13: Solid bars on screen when rebooting with XP.
When running with an 8 MB frame buffer at 1280x1024x32 bpp, line by line
compression is not possible because the display pitch cannot be a power of 2.
The driver attempts to compensate by setting a linear pitch and enabling
another hardware compression mode, called "Frame Dirty Mode". In this mode,
the DV status for the screen is not updated line by line, but frame by frame.
This feature is broken in the hardware in GX processor 2 (see #3642),
therefore frame-dirty compression must be defeatured.
Issue #170.15: Display driver not filtering refresh rates on TFT system.
The driver should now filter non-TFT modes when running on a TFT.
Issue #171.2: Geode GX processor 1.01.01 graphics video playback corruption using
Media Player 6.4, 8.0, or 9.0.
1. Updated DdCreateSurface to fail calls to create an overlay surface when an
overlay is active (fixes this issue)
2. Updated DdUpdateOverlay to fail if an invalid overlay is being updated.
3. Updated DdSetColorKey to fail if a color key is being set for an invalid overlay.
Issue #171.3: Missing drive bitmaps in WinBench 99 test settings window.
Check when creating the bitmap that the format of the bitmap is correct.
When the DDK is misinformed, the bitmap is allocated in system memory.
Issue #171.5: Real Video Playback is jumpy.
The DdGetFlipStatus code was only implemented for graphics flipping. The
RealOne player was checking to see if a video flip was possible and as the
code only checked graphics flip status, a flip was always reported to be possible.
The player was thus occasionally flipping faster than the hardware could display.
Issue #171.7: Geode GX processor 1.01.03 graphics driver fails HCT 11.A GUIMAN GDI
with poly clip test. Brush alignment errors were fixed.
Issue #118.516: SLD file does not import properly. Was rebuilt for Geode SP4GX22
system platform Win XPe graphics driver 1.03.05.
Known Errata
------------
Issue #182.15: Real Video files fail overnight media test.
Description: Real Video files fail overnight media test.
Resolution: This appears to be an application issue.
Issue #170.4: DCT DirectDraw test suite fails 16 tests.
Description: DCT DirectDraw test suite fails 16 tests.
Resolution: The issues identified were manifest due to an earlier test suite
version possibly in concert with an earlier driver version.
