Hugh Redelmeier <hugh@mimosa.com>"> D. Hugh Redelmeier</a> <pre>I finally am trying to set the GART size, as per Alex's <a href="show_bug.cgi?id=61182#c12">comment #12</a>. Without setting it, Xorg0.log reports: [ 15.054] (II) RADEON(0): mem size init: gart size :1fdef000 vram size: s:20000000 visible:1f020000 The default GART size is 512MiB, You'd think that would be a good match for the 512MiB video RAM on my card. This output shows that the GART size is reduced by a somewhat odd number (13^2 * 2^12). When I set radeon.gartsize=1024 on the kernel line, Xorg.0.log reports: [ 14.842] (II) RADEON(0): mem size init: gart size :3fdef000 vram size: s:20000000 visible:1f020000 Again, the GART size is reduced by the same amount. Wait: according to <a href="http://dri.freedesktop.org/wiki/GART/">http://dri.freedesktop.org/wiki/GART/</a> the GART seems to enable the video card to access the computer's memory, not the other way around. So I don't see how this is relevant: we're getting a crash in a CPU instruction that is trying to access the video card's memory.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the assignee for the bug.</li> </ul> </body> </html>
