           Summary: Radeon patch for new chips (R420 etc.), DELL server and
                    bug fixes.
           Product: xorg
           Version: CVS_head
          Platform: PC
        OS/Version: All
            Status: NEW
          Severity: normal
          Priority: P2
         Component: Driver/Radeon
        AssignedTo: xorg-bugzilla-noise at freedesktop.org
        ReportedBy: hyu at ati.com


This patch is derived from a set of patches contributed before DRI merge. The 
old patches have been circulating among developers, some for them have been 
integrated into CVS by Eric Anholt and Alex Deucher. 
This patch has been reworked to sync with the latest CVS code, it contains:
1. New chip support for R420/M18, R423, RV380/M24, RV370/M22, RS350/M (2D only).
   Most code in the patch are for this because of a completely new BIOS 
   architecture. A new file radeon_bios.c is added.
2. Triple-head DELL server support, this shouldn't affect normal user.
3. A few bug fixes:
   Bug fix for HDP problem on 256M cards.
   Bug fix for CRTC source on flat panels.
   Bug fix for external TMDS.
   Bug fix fbLocation with R300 cards.

While merging this patch, I noticed a couple of problems with current CVS code,
but haven't got time to fix them. One is xrender problem -- cause IGP cards to
hang. Another is fbLocation problem -- cause problems with radeonfb. I'll look 
at them latter if no one is working on them.
