From e84f77be215ec1fc7a27388819b6c3a711057e4a Mon Sep 17 00:00:00 2001
From: Eric Anholt <anholt@FreeBSD.org>
Date: Tue, 8 Jun 2004 09:19:17 +0000
Subject: * 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.
