I may have missed some e-mails regarding Alan
Cox's version of the xfree86 cyrix video driver,
and his ping with Alan Hourihane re the "geode"
driver... just to be on the safe side re items
such as these:

Alan Hourihane ([EMAIL PROTECTED]):
> current Cyrix driver in CVS purely deals with the (ISA based) ...

Alan Cox ([EMAIL PROTECTED]):
> Neither 5520 or 5530 actually work with the "cyrix" driver...



- The following applies to Xfree86 4.2.99.1,
made from CVS source 15-oct.

- The cyrix driver as is in the xfree86 CVS does
not work on National's current Centaurus II
development board (GX1+5530). (Presumably it works
on older chipsets, I don't know enough to speak
to that).

- Alan's version of the  cyrix driver, without
the minor patches I made, does not work on the
5530. With the patches it is usable.

- Alan's cyrix driver, on the Centaurus II, is 
using a PCI device.

- With the patches, Alan's cyrix driver works on
the 5530, _if_ compression is not used (one of
the patches addresses this).  It is not perfect,
I cannot "cleanly" reset back to text mode (the
system remains up, but the video becomes garbled).

- The "geode" driver (the NatSemi driver) works well,
although I have not "exercised it" a great deal.


Although the "geode" driver is "the wave of the
future" on the 5530, presumably the "cyrix" driver
should be maintained, if this is low cost, so as
not to "lock up" if used? Also, the cyrix driver
may be a good deal smaller.


My apologies if I've missed something or am beating
a dead horse.
