neomagic - Neomagic video driver
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 mod-
els. 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
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:
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.
On some laptops using the 2160 chipset (MagicGraph 128XD) the following
options are needed to avoid a lock-up of the graphic engine:
Xorg(1), xorg.conf(5), xorgconfig(1), Xserver(1), X(7)
