This section only covers configuration details specific to this +driver. +.PP +The following driver +.B Options +are supported: +.TP +.BI "Option \*qHWCursor\*q \*q" boolean \*q +.TP +.BI "Option \*qSWCursor\*q \*q" boolean \*q +These two options interact to specify hardware or software cursor. If the +SWCursor option is specified, any HWCursor setting is ignored. Thus, either +\*qHWCursor off\*q or \*qSWCursor on\*q 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 automatic panel expansion feature. +Default: hardware cursor. +.TP +.BI "Option \*qNoAccel\*q \*q" boolean \*q +Disable or enable acceleration. Default: acceleration is enabled. +.TP +.BI "Option \*qRotate\*q \*qCW\*q" +.TP +.BI "Option \*qRotate\*q \*qCCW\*q" +Rotate the desktop 90 degrees clockwise or counterclockwise. This option +forces the ShadowFB option on, and disables acceleration. +Default: no rotation. +.TP +.BI "Option \*qShadowFB\*q \*q" boolean \*q +Enable or disable use of the shadow framebuffer layer. See +shadowfb(__drivermansuffix__) for further information. This option +disables acceleration. Default: off. +.TP +.BI "Option \*qLCDClock\*q \*q" frequency \*q +Override the maximum dot clock. Some LCD panels produce incorrect results if +they are driven at too fast of a frequency. If UseBIOS is on, the BIOS will +usually restrict the clock to the correct range. If not, it might be +necessary to override it here. The +.B frequency +parameter may be specified as an integer in Hz (135750000), or with +standard suffixes like "k", "kHz", "M", or "MHz" (as in 135.75MHz). +.TP +.BI "Option \*qUseBIOS\*q \*q" boolean \*q +Enable or disable use of the video BIOS to change modes. Ordinarily, the +.B 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 +.B savage +driver use your mode line timing exactly, turn off the UseBios option. +Default: on (use the BIOS). +.TP +.BI "Option \*qShadowStatus\*q \q*" boolean \*q +Enables the use of a shadow status register. There is a chip bug in the +Savage graphics engine that can cause a bus lock when reading the engine +status register under heavy load, such as when scrolling text or dragging +windows. The bug affects about 4% of all Savage users. If your system +hangs regularly while scrolling text or dragging windows, try turning this +option on. This uses an alternate method of reading the engine status +which is slightly more expensive, but avoids the problem. Default: off +(use normal status register). +.SH FILES +savage_drv.o +.SH "SEE ALSO" +XFree86(1), XF86Config(__filemansuffix__), xf86config(1), Xserver(1), X(__miscmansuffix__) +.SH AUTHORS +Authors include Tim Roberts (timr@probo.com) and Ani Joshi (ajoshi@unixbox.com) +for the 4.0 version, and Tim Roberts and S.
