DESCRIPTION
neomagic is an XFree86 driver for the Neomagic graphics
chipsets found in many laptop computers.
SUPPORTED HARDWARE
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.
CONFIGURATION DETAILS
Please refer to XF86Config(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
XFree86 Version 4.5.0 1
NEOMAGIC(4) UNIX Programmer's Manual NEOMAGIC(4)
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"
