DESCRIPTIONsavage is an XFree86 driver for the S3 Savage family video
accelerator chips. The savage driver supports PCI and AGP
boards with the following chips:
Savage3D (8a20 and 8a21)
Savage4 (8a22)
Savage2000 (9102)
Savage/MX (8c10 and 8c11)
Savage/IX (8c12 and 8c13)
ProSavage PM133 (8a25)
ProSavage KM133 (8a26)
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 "HWCursor" "boolean"
Option "SWCursor" "boolean"
These two options interact to specify hardware or
software cursor. If the SWCursor option is speci-
fied, any HWCursor setting is ignored. Thus,
either "HWCursor off" or "SWCursor on" will force
the use of the software cursor. On Savage/MX and
Savage/IX chips which are connected to LCDs, a
software cursor will be forced, because the Savage
hardware cursor does not correctly track the auto-
matic panel expansion feature. Default: hardware
cursor.
Option "NoAccel" "boolean"
Disable or enable acceleration. Default: accelera-
tion is enabled.

Option "Rotate" "CW"
Option "Rotate" "CCW"
Rotate the desktop 90 degrees clockwise or counter-
clockwise. This option forces the ShadowFB option
on, and disables acceleration. Default: no rota-
tion.
Option "ShadowFB" "boolean"
Enable or disable use of the shadow framebuffer
layer. See shadowfb(4) for further information.
This option disables acceleration. Default: off.
Option "UseBIOS" "boolean"
Enable or disable use of the video BIOS to change
modes. Ordinarily, the savage driver tries to use
the video BIOS to do mode switches. This generally
produces the best results with the mobile chips
(/MX and /IX), since the BIOS knows how to handle
the critical but unusual timing requirements of the
various LCD panels supported by the chip. To do
this, the driver searches through the BIOS mode
list, looking for the mode which most closely
matches the XF86Config mode line. Some purists
find this scheme objectionable. If you would
rather have the savage driver use your mode line
timing exactly, turn off the UseBios option.
Default: on (use the BIOS).
