What's in this patch?
Binaries
This patch provides an update to the AMD Geode LX800 graphics driver for the x86 target, devg-lx800.so, shipped with the AMD Geode LXDB800 BSP 1.0.0.
|
The devg-lx800.so that ships with the AMD Geode LXDB800 BSP 1.0.0 uses the video BIOS to detect and set the video modes. This new driver no longer depends on the video BIOS and programs the video mode directly. |
Configuration file
You can use the geode.conf driver configuration file, included in this patch, to override the default dot clock setting calculated by the driver. In most situations, this shouldn't be required.
Different combinations of resolutions and refresh rates require different dot clock settings. The geode.conf is self-documenting, and describes how to specify the divider settings for the Dot Clock PLL. See the AMD Geode LX Processors Data Book, "6.14.2.14 GLCP Dot Clock PLL Control" section for more information on the setting of the PLL.
Here are some sample io-graphics command lines to start the driver in 1024x768 mode.
Let the driver calulate Dot Clock PLL settings:
io-graphics -dlx800 vid=0x1022,did=0x2081,index=0,photon,xres=1024,yres=768,bitpp=16 -pphoton
Specifie geode.conf to override the driver settings for Dot Clock PLL:
io-graphics -dlx800 vid=0x1022,did=0x2081,index=0,photon,xres=1024,yres=768,bitpp=16,mode_opts=/usr/photon/config/geode.conf -pphoton
Installed files
The following files are installed:
- $QNX_TARGET/x86/lib/dll/devg-lx800.so
- $QNX_TARGET/x86/usr/photon/config/geode.conf
Fixed issues
- 48039 -- a lockup produced by running pidin repeatedly in a pterm window is fixed.
Known issues
- 50051 -- The devg-lx800.so driver doesn't support these resolution / refresh rate combinations:
- 1400x1050 60Hz
- 1152x864 85Hz
- 51369 -- Under Neutrino 6.3.0 SP3, the devg-lx800.so driver lists several unsupported resolutions under phgrafx:
- 2048 X 1536
- 1920 X 1200
- 1680 X 1050
- 1440 X 900
- 1280 X 800
