This rearranges the r128 code to use the Crtc and Output interfaces which should make the driver easier to maintain in the long run. User visible changes include DDC detection working in more cases and the ability to have multiple monitors with DRI. Some choices have been made to conserve memory. Modes can be switched up to the highest resolution in xorg.conf. If this is 1024x768 for example, the front buffer will be 1024x768 instead of 1024x1024. This means 90 and 270 degree rotations will not work. However, scalings, reflection and 180 degree rotations can be set with the xrandr client program.

1. Supported Hardware
o ATI Rage 128 based cards
2. Features
o Full support (including hardware accelerated 2D drawing) for 8, 15,
16, 24 bit pixel depths.
o Hardware cursor support to reduce sprite flicker.
o Support for high resolution video modes up to 1800x1440 @ 70Hz.
o Support for doublescan video modes (e.g., 320x200 and 320x240).
o Support for gamma correction at all pixel depths.
o Fully programmable clock supported.
o Robust text mode restore for VT switching.
3. Technical Notes
o None
4. Reported Working Video Cards
o Rage Fury AGP 32MB
o XPERT 128 AGP 16MB
o XPERT 99 AGP 8MB
5. Configuration
The driver auto-detects all device information necessary to initialize
the card. The only lines you need in the "Device" section of your
xorg.conf file are:
Section "Device"
Identifier "Rage 128"
Driver "r128"
EndSection
or let xorgconfig do this for you.
However, if you have problems with auto-detection, you can specify:
o VideoRam - in kilobytes
o MemBase - physical address of the linear framebuffer
o IOBase - physical address of the memory mapped IO registers
o ChipID - PCI DEVICE ID
6. Driver Options
o "hw_cursor" - request hardware cursor (default)
o "sw_cursor" - software cursor only
o "no_accel" - software rendering only
o "dac_8_bit" - use color weight 888 in 8 bpp mode (default)
o "dac_6_bit" - use color weight 666 in 8 bpp mode (VGA emulation)
7. Known Limitations
o None

The X11R7.5 driver was originally part of XFree86 4.4 rc2.
The XFree86 4 driver was ported from XFree86 3.3.x and enhanced by:
o Rickard E. (Rik) Faith <mailto:faith@precisioninsight.com>
o Kevin E. Martin <mailto:kevin@precisioninsight.com>
The XFree86 4 driver was funded by ATI and was donated to The XFree86
Project by:

USA
The XFree86 3.3.x driver used for the port was written by:
o Rickard E. (Rik) Faith <mailto:faith@precisioninsight.com>
o Kevin E. Martin <mailto:kevin@precisioninsight.com>
The XFree86 3.3.x driver was funded by ATI and was donated to The
XFree86 Project by Precision Insight, Inc. It was based in part on
an earlier driver that was written by:
o Alan Hourihane <mailto:alanh@fairlite.demon.co.uk>
o Dirk Hohndel <mailto:hohndel@suse.de>
