neomagic is an Xorg driver for the Neomagic graphics chipsets found in
many laptop computers.
neomagic supports the following chipsets:
- MagicGraph 128 (NM2070)
- MagicGraph 128V (NM2090)
- MagicGraph 128ZV (NM2093)
- MagicGraph 128ZV+ (NM2097)
- MagicGraph 128XD (NM2160)
- MagicGraph 256AV (NM2200)
- MagicGraph 256AV+ (NM2230)
- MagicGraph 256ZX (NM2360)
- MagicGraph 256XL+ (NM2380)
The driver supports depths 8, 15, 16 and 24 for all chipsets except the NM2070
which does not support depth 24. All depths are accelerated except for depth
24 which is only accelerated on NM2200 and newer models. All visuals are
supported in depth 8. TrueColor and DirectColor visuals are supported in the
other depths.
Please refer to
xorg.conf(5) for general configuration details. This section
only covers configuration details specific to this driver.
The following driver
Options are supported
-
Option "NoAccel"
"boolean"
- Disable or enable acceleration. Default: acceleration is
enabled.
-
Option "SWCursor"
"boolean"
- Disable or enable software cursor. Default: software cursor
is disable and a hardware cursor is used.
-
Option "PCIBurst"
"boolean"
- Disable or enable PCI burst modes. Default: enabled.
- Option "Rotate" "CW"
- Option "Rotate" "CCW"
- Rotate the display clockwise or counterclockwise. This mode
is unaccelerated. Default: no rotation.
-
Option "ShadowFB"
"boolean"
- Enable or disable use of the shadow framebuffer layer.
Default: off.
-
Option "OverlayMem"
"integer"
- Reserve the given amount of memory (in bytes) for the
XVideo overlay. On boards with limited memory, display of large XVideo
buffers might fail due to insufficient available memory. Using this option
solves the problem at the expense of reducing the memory available for
other operations. For full-resolution DVDs, 829440 bytes (720x576x2) are
necessary.
Note
On some laptops using the 2160 chipset (MagicGraph 128XD) the following options
are needed to avoid a lock-up of the graphic engine:
Option "XaaNoScanlineImageWriteRect"
Option "XaaNoScanlineCPUToScreenColorExpandFill"
Xorg(1),
xorg.conf(5),
Xserver(1),
X(7)
