From 45f26f9979f19e1d15b78a5a3ef47092e6c9cbbf Mon Sep 17 00:00:00 2001 From: Felix Kuehling Date: Sat, 12 Mar 2005 23:00:53 +0000 Subject: Removed savagedma.[ch]. They have been unused for a while and were only kept around for reference. Now that command DMA is implemented in the DRM module they are no longer needed. --- src/mesa/drivers/dri/savage/savagedma.c | 209 -------------------------------- src/mesa/drivers/dri/savage/savagedma.h | 52 -------- 2 files changed, 261 deletions(-) delete mode 100644 src/mesa/drivers/dri/savage/savagedma.c delete mode 100644 src/mesa/drivers/dri/savage/savagedma.h (limited to 'src/mesa/drivers/dri') diff --git a/src/mesa/drivers/dri/savage/savagedma.c b/src/mesa/drivers/dri/savage/savagedma.c deleted file mode 100644 index 51a1e6d2bd..0000000000 --- a/src/mesa/drivers/dri/savage/savagedma.c +++ /dev/null @@ -1,209 +0,0 @@ -/* - * Copyright 1998-2003 VIA Technologies, Inc.
