Bug 4007

Hello, 
 
i have been reading the documentation in the 6.8.2 tree 
  and found some things that may be bugs or omissions : 
 
xc/programs/Xserver/hw/xfree86/doc/README.ati contains : 
 
  is dated februari 2002, 
    but i think ati was significantly changed since then ; 
  forgot to update date mentioned in file, or outofdate document ? 
 
  "a linear aperture is often used." 
  can i get X to tell me what it is ? can my apps directly write to it ? 
 
  'acceleration does not require a linear video memory aperture', 
    but also 
  'on non-intel platforms, the driver requires a linear aperture'. 
 
  option backingstore : what is it's default ? does it need an argument ? 
    are these described elsewhere ? 
 
  there is no description of option 'DACSpeed', 
    though it is mentioned under 'known problems' 
    would 'DACSpeed 200MHz' be correct syntax ? (works for me). 
    is it described elsewhere ? 
 
  List of chipsets does not include my mach64 : 
  Output of lspci is : 
    0000:00:08.0 VGA compatible controller: 
    ATI Technologies Inc 3D Rage II+ 215GTB [Mach64 GTB] (rev 9a) 
  It is built onto motherboard of my PackardBell Pentium 1 MMX 200MHz. 
  I remember having (years ago) seen output that said it could do 200 MHz, 
    i think this was output of the card itself, 
  X has always refused modelines with more than 170 MHz, 
    so i tried option DACSpeed 200MHz, 
    and tried a videomode with a clock of 189 MHz, 
    which worked without problem. 
  If you want a test with full 200MHz, let me know. 
 
  "A resolution of 1400 x 1050 is not normally possible for CRTs 
    to synchronize to", it says, but 
    (60Hz,10% vertical retrace, 70kHz, 20% horizontal retrace, 122MHz) 
    should be doable for a multi-sync ; at least mine can do it. 
 
 
I also have a question : 
  i am seeing some strange output on my Debian stable (xfree86 based) system, 
  for example, list of available Visuals contains two sets of four identical 
  Visuals ; 
Can these be reported to xorg (meaningfully, i mean), 
  and should these be reported on X or on the mach64 driver ? 
(I am preparing to build xorg, 
   but if and when that succeeds remains to be seen) 
 
have fun !
