.SH DESCRIPTION
|
|
.B cyrix
|
|
is an __xservername__ driver for the Cyrix MediaGX (now Natsemi Geode) series of
|
|
processors when using the built in video.
|
|
.SH SUPPORTED HARDWARE
|
|
The
|
|
.B cyrix
|
|
driver supports the MediaGX, MediaGXi and MediaGXm processors, as well as
|
|
the Natsemi 'Geode' branded processors. It supports the CS5510, CS5520,
|
|
CS5530 and CS5530A companion chips. The driver supports 4, 8, 15 and 16 bit
|
|
deep displays with video compression and acceleration.
|
|
.PP
|
|
The MediaGX run length compresses its shared framebuffer, for the best
|
|
performance on a MediaGX machine pick backgrounds that compress well
|
|
horizonally.
|
|

.SH "BUGS"
|
|
This driver has not been tested on the original 5510 hardware for some
|
|
considerable time.
|
|
.PP
|
|
8bit mode does not currently work on the CS5510 with external RAMDAC.
|
|
.PP
|
|
The 5530A video overlay facility is not currently supported.
|
|
.PP
|
|
__xservername__ uses the MediaGX 'SoftVGA' interface. On a small number of boards
|
|
this is buggy and may result in strange illegal instruction traps.
|
|
.PP
|
|
Hardware cursors are not currently supported.
