Eric Anholt 6bdf3d36ea Add file missed in last commit: Bug #748:
- Add Render acceleration for Radeon 100 and 200-series cards, enabled by
    default. Notable performance gains include 27fps in cairogears instead
    of 6fps (compared to 50 with glitz), and my disks are now the
    bottleneck in an ls -lR in gnome-terminal. Only supported in DRI mode
    because the MMIO submission hangs the card so far, but the code is left
    in because it may be supportable soon.
- Add xorg.conf options to disable Render acceleration and to force the
    subpixel order in the server (Hui Yu).
Many thanks to Hui Yu at ATI for the code this was based off of, Michel
    Daenzer for bugfixes and suggestions, and LinuxFund for sponsoring the
    work.

<sect>Supported Hardware
<p>
<itemize>
  <item>ATI Rage 128 based cards
</itemize>


<sect>Features
<p>
<itemize>
  <item>Full support (including hardware accelerated 2D drawing) for 8, 15,
        16, 24 bit pixel depths.
  <item>Hardware cursor support to reduce sprite flicker.
  <item>Support for high resolution video modes up to 1800x1440 @ 70Hz.
  <item>Support for doublescan video modes (e.g., 320x200 and 320x240).
  <item>Support for gamma correction at all pixel depths.
  <item>Fully programmable clock supported.
  <item>Robust text mode restore for VT switching.
</itemize>


<sect>Technical Notes
<p>
<itemize>
  <item>None
</itemize>


<sect>Reported Working Video Cards
<p>
<itemize>
  <item>Rage Fury AGP 32MB
  <item>XPERT 128 AGP 16MB
  <item>XPERT 99 AGP 8MB
</itemize>


<sect>Configuration
<p>
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:
<verb>
       Section "Device"
           Identifier "Rage 128"
           Driver     "r128"
       EndSection
</verb>
or let <tt>xorgconfig</tt> do this for you.

However, if you have problems with auto-detection, you can specify:
<itemize>
  <item>VideoRam - in kilobytes
  <item>MemBase  - physical address of the linear framebuffer
  <item>IOBase   - physical address of the memory mapped IO registers
  <item>ChipID   - PCI DEVICE ID
</itemize>


<sect>Driver Options
<p>
<itemize>
  <item>"hw_cursor" - request hardware cursor (default)
  <item>"sw_cursor" - software cursor only
  <item>"no_accel"  - software rendering only
  <item>"dac_8_bit" - use color weight 888 in 8 bpp mode (default)
  <item>"dac_6_bit" - use color weight 666 in 8 bpp mode (VGA emulation)
</itemize>


<sect>Known Limitations
<p>
<itemize>
  <item>None

The X11R&relvers; driver was originally part of XFree86 4.4 rc2.

The XFree86 4 driver was ported from XFree86 3.3.x and enhanced by:
