DESCRIPTION

17       siliconmotion  is  an Xorg driver for Silicon Motion based video cards.
18       The driver is fully accelerated, and provides support for the following
19       framebuffer  depths: 8, 16, and 24.  All visual types are supported for
20       depth 8, and TrueColor visuals are supported for the other depths.
21

CONFIGURATION DETAILS

43       Please  refer  to xorg.conf(5) for general configuration details.  This
44       section only covers configuration details specific to this driver.  All
45       options  names  are case and white space insensitive when parsed by the
46       server, for example,  "lynxe" and "LynxE" are equivalent.
47
48       Multihead mode configuration is done  through  the  RandR1.2  interface
49       (see  xorg.conf(5)  and  xrandr(1)  for  further information). Hardware
50       accelerated screen rotation and framebuffer resizing are only supported
51       with  the  EXA  acceleration  architecture  (see the AccelMethod option
52       below).
53
54       The driver auto-detects the chipset type,  but  the  following  ChipSet
55       names  may optionally be specified in the config file "Device" section,
56       and will override the auto-detection:
57
58           "lynx",  "lynxe",   "lynx3d",   "lynxem",   "lynxem+",   "lynx3dm",
59           "cougar3dr", "msoc".
60
61
62       The following Cursor Options are supported:
63
64       Option "HWCursor" "boolean"
65              Enable or disable the HW cursor.  Default: on.
66
67       Option "SWCursor" "boolean"
68              Inverse of "HWCursor".  Default: off.
69
70
71       The following display Options are supported:
72
73       Option "VideoKey" "integer"
74              Set the video color key.  Default: a little off full blue.
75
76       Option "ByteSwap" "boolean"
77              Turn  on  byte  swapping  for  capturing  using  SMI demo board.
78              Default: off.
79
80       Option "Interlaced" "boolean"
81              Turn on interlaced video capturing.  Default: off.
82
83       Option "UseBIOS" "boolean"
84              Use the BIOS to set the modes. This is  used  for  custom  panel
85              timings.  Default: off for SM72x and SM5xx, otherwise on.
86
87       Option "Dualhead" "boolean"
88              Enable dualhead mode.  Currently not all chips are supported and
89              hardware video overlay (XV) support may have  some  limitations.
90              Default: off.
91
92       Option "PanelSize" "widthxheight"
93              Override LCD panel dimension autodetection.
94
95       Option "UseFBDev" "boolean"
96              Don't actually program the hardware mode registers, but leave it
97              as set by the operating system. Only available  on  MSOC  chips.
98              Default: off.
99
100       Option "CSCVideo" "boolean"
101              CSC  video  uses color space conversion to render video directly
102              to the framebuffer, without using an overlay.  Only available on
103              MSOC chips. Default: on.
104
105       The following video memory Options are supported:
106
107       Option "mclk" "integer"
108              Sets  the memory clock. You must specify the units.  For example
109              50Mhz is the same as 50000Khz or 50000000Hz.  On MSOC chips this
110              is  the main clock source for all functional blocks, such as the
111              2D engine, GPIO, Video Engine, and DMA Engine.  This  option  is
112              only  used for debugging purposes on MSOC chips.  Default: probe
113              the memory clock value, and use it at server start.
114
115       Option "mxclk" "integer"
116              Sets the memory clock. You must specify the units.  For  example
117              50Mhz  is  the same as 50000Khz or 50000000Hz.  Clock source for
118              the local SDRAM controller. This option  is  only  available  on
119              MSOC chips and used only for debugging purposes.  Default: probe
120              the memory clock value, and use it at server start.
121
122       The following acceleration and graphics engine Options are supported:
123
124       Option "NoAccel"
125              Disable acceleration.  Very useful for determining if the driver
126              has  problems  with  drawing and acceleration routines.  This is
127              the first option to try if your server runs but you see  graphic
128              corruption on the screen.  Using it decreases performance, as it
129              uses software emulation for drawing operations the video  driver
130              can accelerate with hardware.  Default: acceleration is enabled.
131
132       Option "AccelMethod" "string"
133              Chooses  between  available  acceleration  architectures.  Valid
134              options are XAA and EXA.  XAA is  the  traditional  acceleration
135              architecture  and support for it is very stable.  EXA is a newer
136              acceleration architecture with better performance for the Render
137              and Composite extensions, but the rendering code for it is newer
138              and possibly unstable.  The default is XAA.
139
140
141       The following PCI bus Options are supported:
142
143       Option "PciBurst" "boolean"
144              will enable PCI burst mode. This should work on all  but  a  few
145              broken  PCI  chipsets,  and will increase performance.  Default:
146              on.
147
148       Option "PciRetry" "boolean"
149              will allow the driver to rely on PCI Retry to program the regis‐
150              ters.   PciBurst  must  be  enabled for this to work.  This will
151              increase performance, especially for small fills/blits,  because
152              the driver does not have to poll the card before sending it com‐
153              mands to make sure it is ready. It should work  on  most  recent
154              PCI chipsets.  Default: value of PciBurst option.
