.SH DESCRIPTION
|
|
.B mga
|
|
is an __xservername__ driver for Matrox video cards. The driver is fully
|
|
accelerated, and provides support for the following framebuffer depths: 8,
|
|
15, 16, 24, and an 8+24 overlay mode. All visual types are supported for
|
|
depth 8, and both TrueColor and DirectColor visuals are supported for the
|
|
other depths except 8+24 mode which supports PseudoColor, GrayScale and
|
|
TrueColor. Multi\-card configurations are supported. XVideo is supported
|
|
on G200 and newer systems, with either
|
|
.B TexturedVideo
|
|
or video overlay. The second head of dual\-head cards is supported for the
|
|
G450 and G550. Support for the second head on G400 cards requires a
|
|
binary\-only "mga_hal" module that is available from Matrox
|
|
<http://www.matrox.com>, and may be on the CD supplied with the card. That
|
|
module also provides various other enhancements, and may be necessary to
|
|
use the DVI (digital) output on the G550 (and other cards).
|
|
.SH "SUPPORTED HARDWARE"
|
|
The
|
|
.B mga
|
|
driver supports PCI and AGP video cards based on the following Matrox
|
|
chips. They are listed in approximate chronological order of production
|
|
(with the most recent chipsets listed last), so consult this list when you
|
|
are unsure whether your card is meant when references are made to \(oqG200
|
|
and later\(cq chips, for example.

.SH "CONFIGURATION DETAILS"
|
|
Please refer to __xconfigfile__(__filemansuffix__) for general configuration
|
|
details. This section only covers configuration details specific to this
|
|
driver.
|
|
.PP
|
|
The driver auto\-detects the chipset type, but the following
|
|
.B ChipSet
|
|
names may optionally be specified in the config file
|
|
.B \*qDevice\*q
|
|
section, and will override the auto\-detection:
|
|
.PP
|
|
.RS 4
|
|
"mga2064w", "mga1064sg", "mga2164w", "mga2164w agp", "mgag100", "mgag200",
|
|
"mgag200 pci", "mgag400", "mgag550".
|
|
.RE
|
|
.PP
|
|
The G450 is Chipset "mgag400" with ChipRev 0x80.
|
|
.PP
|
|
The driver will auto\-detect the amount of video memory present for all
|
|
chips except the Millennium II. In the Millennium II case it defaults
|
|
to 4096\ kBytes. When using a Millennium II, the actual amount of video
|
|
memory should be specified with a
|
|
.B VideoRam
|
|
entry in the config file
|
|
.B \*qDevice\*q
|
|
section.
|
|
.PP
|
|
The following driver
|
|
.B Options
|
|
are supported:
|
|
.TP
|
|
.BI "Option \*qColorKey\*q \*q" integer \*q
|
|
Set the colormap index used for the transparency key for the depth 8 plane
|
|
when operating in 8+24 overlay mode. The value must be in the range
|
|
2\-255. Default: 255.
|
|
.TP
|
|
.BI "Option \*qHWCursor\*q \*q" boolean \*q
|
|
Enable or disable the HW cursor. Default: on.
|
|
.TP
|
|
.BI "Option \*qMGASDRAM\*q \*q" boolean \*q
|
|
Specify whether G100, G200 or G400 cards have SDRAM. The driver attempts to
|
|
auto\-detect this based on the card's PCI subsystem ID. This option may
|
|
be used to override that auto\-detection. The
|
|
.B mga
|
|
driver is not able to auto\-detect the presence of of SDRAM on secondary
|
|
heads in multihead configurations so this option will often need to be
|
|
specified in multihead configurations. Default: auto\-detected.
|
|
.TP
|
|
.BI "Option \*qNoAccel\*q \*q" boolean \*q
|
|
Disable or enable acceleration. Default: acceleration is enabled.
|
|
.TP
|
|
.BI "Option \*qAccelMethod\*q \*q" "string" \*q
|
|
Chooses between available acceleration architectures. Valid options are
|
|
.B XAA
|
|
and
|
|
.B 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
|
|
possibly unstable. The default is
|
|
.B XAA.
|
|
.TP
|
|
.BI "Option \*qNoHal\*q \*q" boolean \*q
|
|
Disable or enable loading the "mga_hal" module. Default: the module is
|
|
loaded when available and when using hardware that it supports.
|
|
.TP
|
|
.BI "Option \*qOverclockMem\*q"
|
|
Set clocks to values used by some commercial X Servers (G100, G200 and G400
|
|
only). Default: off.
|
|
.TP
|
|
.BI "Option \*qPciRetry\*q \*q" boolean \*q
|
|
Enable or disable PCI retries. Default: off.
|
|
.TP
|
|
.BI "Option \*qRotate\*q \*qCW\*q"
|
|
.TP
|
|
.BI "Option \*qRotate\*q \*qCCW\*q"
|
|
Rotate the display clockwise or counterclockwise. This mode is unaccelerated.
|
|
Default: no rotation.
|
|
.TP
|
|
.BI "Option \*qShadowFB\*q \*q" boolean \*q
|
|
Enable or disable use of the shadow framebuffer layer. Default: off.
|
|
.TP
|
|
.BI "Option \*qSyncOnGreen\*q \*q" boolean \*q
|
|
Enable or disable combining the sync signals with the green signal.
|
|
Default: off.
|
|
.TP
|
|
.BI "Option \*qUseFBDev\*q \*q" boolean \*q
|
|
Enable or disable use of on OS\-specific fb interface (and is not supported
|
|
on all OSs). See fbdevhw(__drivermansuffix__) for further information.
|
|
Default: off.
|
|
.TP
|
|
.BI "Option \*qVideoKey\*q \*q" integer \*q
|
|
This sets the default pixel value for the YUV video overlay key.
|
|
Default: undefined.
|
|
.TP
|
|
.BI "Option \*qTexturedVideo\*q \*q" boolean \*q
|
|
This has XvImage support use the texture engine rather than the video
|
|
overlay. This option is only supported by G200 and later chips, and only
|
|
at 16 and 32 bits per pixel.
|
|
Default: off.
|
|
.TP
|
|
.BI "Option \*qOldDmaInit\*q \*q" boolean \*q
|
|
This forces the driver to use the old DMA initialization path for DRI.
|
|
Use this option only to support a older version of the DRI driver with
|
|
a newer DRM (version 3.2 or later). This option also disables the use
|
|
of direct rendering on PCI cards.
|
|
Default: off.
|
|
.TP
|
|
.BI "Option \*qForcePciDma\*q \*q" boolean \*q
|
|
This forces the use of PCI DMA even if AGP DMA could be used. This
|
|
option is primarily intended for testing purposes, but it could also
|
|
be used on systems with a buggy or poorly function AGP implementation.
|
|
Default: off.
