From e84f77be215ec1fc7a27388819b6c3a711057e4a Mon Sep 17 00:00:00 2001

Subject: [PATCH] * Convert to use t_vertex.c instead of sis_vb.[ch] * Don't
 dispatch vertices directly to MMIO; queue them up in dma-like buffers  
 first.  This makes things more uniform between AGP and MMIO paths, cleans up 
  some locking ugliness, and makes the driver look more like other drivers. *
 Don't use the AGP Cmd buffer provided by the server.  Instead allocate one in
   the client, which avoids the need for lots of synchronization stuff. * Mark
 some MMIO accesses volatile that should have been. * Disable the AGP
 submission path by default (agp_disable=true) due to   unresolved issues in
 the new code.  The old code had its own (serious) errors   with AGP, so this
 is not really a step backwards.
