     19   1.  Supported Hardware
     20 
     21   This is an XAA accelerated driver for the SGI newport cards (a.k.a. XL)
     22   as found in the SGI Indy and Indigo2. Both the 8bit and 24bit versions
     23   are tested and working.
     24 
     25 
     26   2.  Features
     27 
     28 
     29   o  Support for 8 and 24 bit pixel depths
     30 
     31   o  Hardware cursor support to reduce flicker
     32 
     33   o  Acceleration of XAA operations for both XL8 and XL24 cards
     34 
     35 
     36   3.  Notes
     37 
     38 
     39   o  X -configure does not generate a xorg.conf file.
     40 
     41   o  There's support for both 1024x768 and 1280x1024 modes, but with
     42      some caveats/bugs around timing.
     43 
     44   o  Operating in 8 bit mode will use an 8 bit PseudoColor configuration
     45      with private colour maps, rather than the hardware 24 -> 8 bit colour
     46      dithering support.
     47 
     48   o  The XAA Acceleration support is slightly different for XL8 versus XL24.
     49 
     50   4.  Configuration
     51 
     52   The driver auto-detects all device information necessary to initialize
     53   the card on the Indy. The only lines you need in the "Device" section
     54   of your xorg.conf file are:
     55 
     56          Section "Device"
     57              Identifier "SGI newport"
     58              Driver     "newport"
     59          EndSection
     60 
     61 
     62   Indigo2 users have to use the BusID option as documented below.
     63 
     64   However, if you have problems with auto-detection, you can specify:
     65 
     66   o  bitplanes - number of physical bitplanes (8 or 24)
     67 
     68   o  HWCursor - enable or disable hardware cursor
     69 
     70   o  BusID - set this to "1" on the Indigo2 XL
     71 
     72   o  NoAccel - disable Acceleration Options
     73 
     74   o  XmapTiming - Set the XMAP9 Mode Timing - 1 for Fast, 2 for Slow,
     75      3 for Very Slow.  Since the driver currently doesn't parse all of
     76      the monitor information, you may need to set the Timing to 2
     77      (ie Slow) for 1024x760 60Hz operation.  Very Slow is likely for
     78      NTSC/PAL timings which we currently don't have a way to configure.
