You need the mmap-2.2.3 driver installed on your system. If you don't have the mmap-2.2.3 driver installed, you could use the driver source in the file
xc/programs/Xserver/hw/xfree86/etc/mmapSVR3.sharor
/usr/X11R6/lib/X11/etc/mmapSVR3.sharBuild and install the driver as instructed. You'll need the file /usr/include/sys/mmap.h for compiling the X11R6/XFree86 source tree, with linear addressing enabled.
The new loadable X Server is not tested to work without linear addressing.
To use the linear address-mapping of the framebuffer you need the mmap Driver by Thomas Wolfram (Version 2.2.3) installed in your Kernel. If you have installed it, most servers will use linear addressing by default. Others may require setting the
Option "linear"in your XF86Config. Check the appropriate manual pages for details. Maybe you need also the MemBase specified in XF86Config. Please refer to the appropriate README of your Card/Server, for How to use...
I could only test these cards on Interactive UNIX
with 32MB MainMemory installed I couldn't use it. My tests with different mappings into the address space results in no Graphics displayed or a spontaneous reboot.
with 32MB MainMemory installed I could map the CardMemory at MemBase 0x07c00000. I could work with all clients until I try to activate a Motif 1.1.1 InputField inside a Motif Client like Mosaic-2.4 or xplan. This results in a crash of the XServer.
!!! You could work around this !!!
Expand your .Xdefaults with
*blinkRate: 0
*cursorPositionVisible: false
This bug seems to be fixed since 3.1.2, and therefore the workaround is not needed anymore.
if you experience a Problem with this Card you could try to use the older Chipset Driver instead "newmmio".
If you declare
Chipset "mmio_928"
inside your XF86Config, it may be alright again.
With the current XF86_S3 I don't encounter any problem.
