NAMEsiliconmotion - Silicon Motion video driver
SYNOPSISSection "Device" Identifier "devname" Driver "siliconmotion" ... [ Option "optionname" ["optionvalue"]] EndSection
DESCRIPTIONsiliconmotion is an Xorg driver for Silicon Motion based video cards. The driver is fully accelerated, and provides support for the following framebuffer depths: 8, 16, and 24. All visual types are supported for depth 8, and TrueColor visuals are supported for the other depths.
SUPPORTED HARDWAREThe siliconmotion driver supports PCI and AGP video cards based on the following Silicon Motion chips: Lynx SM910 LynxE SM810 Lynx3D SM820 LynxEM SM710 LynxEM+ SM712 Lynx3DM SM720 Cougar3DR SM731 MSOC SM501,SM502
CONFIGURATION DETAILSPlease refer to xorg.conf(5) for general configuration details. This section only covers configuration details specific to this driver. All options names are case and white space insensitive when parsed by the server, for example, "lynxe" and "LynxE" are equivalent. Multihead mode configuration is done through the RandR1.2 interface (see xorg.conf(5) and xrandr(1) for further information). Hardware accelerated screen rotation and framebuffer resizing are only supported with the EXA acceleration architecture (see the AccelMethod option below). The driver auto-detects the chipset type, but the following ChipSet names may optionally be specified in the config file "Device" section, and will override the auto-detection: "lynx", "lynxe", "lynx3d", "lynxem", "lynxem+", "lynx3dm", "cougar3dr", "msoc". The following Cursor Options are supported: Option "HWCursor" "boolean" Enable or disable the HW cursor. Default: on. Option "SWCursor" "boolean" Inverse of "HWCursor". Default: off. The following display Options are supported: Option "VideoKey" "integer" Set the video color key. Default: a little off full blue. Option "ByteSwap" "boolean" Turn on byte swapping for capturing using SMI demo board. Default: off. Option "Interlaced" "boolean" Turn on interlaced video capturing. Default: off. Option "UseBIOS" "boolean" Use the BIOS to set the modes. This is used for custom panel timings. Default: off for SM72x and SM5xx, otherwise on. Option "Dualhead" "boolean" Enable dualhead mode. Currently not all chips are supported and hardware video overlay (XV) support may have some limitations. Default: off. Option "PanelSize" "widthxheight" Override LCD panel dimension autodetection. Option "UseFBDev" "boolean" Don't actually program the hardware mode registers, but leave it as set by the operating system. Only available on MSOC chips. Default: off. Option "CSCVideo" "boolean" CSC video uses color space conversion to render video directly to the framebuffer, without using an overlay. Only available on MSOC chips. Default: on. The following video memory Options are supported: Option "mclk" "integer" Sets the memory clock. You must specify the units. For example 50Mhz is the same as 50000Khz or 50000000Hz. On MSOC chips this is the main clock source for all functional blocks, such as the 2D engine, GPIO, Video Engine, and DMA Engine. This option is only used for debugging purposes on MSOC chips. Default: probe the mem‐ ory clock value, and use it at server start. Option "mxclk" "integer" Sets the memory clock. You must specify the units. For example 50Mhz is the same as 50000Khz or 50000000Hz. Clock source for the local SDRAM controller. This option is only available on MSOC chips and used only for debugging purposes. Default: probe the memory clock value, and use it at server start. The following acceleration and graphics engine Options are supported: Option "NoAccel" Disable acceleration. Very useful for determining if the driver has problems with drawing and acceleration routines. This is the first option to try if your server runs but you see graphic corruption on the screen. Using it decreases performance, as it uses software emulation for drawing operations the video driver can acceler‐ ate with hardware. Default: acceleration is enabled. Option "AccelMethod" "string" Chooses between available acceleration architectures. Valid options are XAA and EXA. XAA is the traditional acceleration architecture and support for it is very stable. EXA is a newer acceleration architecture with better performance for the Render and Composite extensions, but the rendering code for it is newer and possi‐ bly unstable. The default is XAA. The following PCI bus Options are supported: Option "PciBurst" "boolean" will enable PCI burst mode. This should work on all but a few broken PCI chipsets, and will increase performance. Default: on. Option "PciRetry" "boolean" will allow the driver to rely on PCI Retry to program the registers. PciBurst must be enabled for this to work. This will increase performance, especially for small fills/blits, because the driver does not have to poll the card before sending it commands to make sure it is ready. It should work on most recent PCI chipsets. Default: value of PciBurst option.

SUPPORTFor assistance with this driver, or Xorg in general, check the web site at http://www.x.org/. If you find a problem with Xorg or have a question not answered in the FAQ please use our bug report form available on the web site or send mail to @lists.freedesktop.org. When reporting problems with the driver send as much detail as possible, including chipset type, a server output log, and operating system specifics.
