From 5b183080eeed7fd32c25e737c12bf23f790227f2 Mon Sep 17 00:00:00 2001 From: Kenneth R Westerback Date: Mon, 18 Feb 2002 01:55:31 +0000 Subject: Add trm - driver for Tekram TRM-S1040 cards (DC395U/UW/F,DC315/U). Thanks to Tekram for donating a couple of cards and a NetBSD driver by Erich Chen of Tekram. Thanks to Martin Akesson for a first port of the NetBSD driver to OpenBSD and thanks to Ashley Martens for the major cleanup to make it presentable and style(9)ish. Only tested on i386 at this time. --- sys/dev/pci/trm_pci.c | 169 ++++++++++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 169 insertions(+) create mode 100644 sys/dev/pci/trm_pci.c (limited to 'sys/dev/pci/trm_pci.c') diff --git a/sys/dev/pci/trm_pci.c b/sys/dev/pci/trm_pci.c new file mode 100644 index 00000000000..32d39e0d56d --- /dev/null +++ b/sys/dev/pci/trm_pci.c @@ -0,0 +1,169 @@ +/* $OpenBSD: trm_pci.c,v 1.1 2002/02/18 01:55:30 krw Exp $ + * ------------------------------------------------------------ + * O.S : OpenBSD + * FILE NAME : trm_pci.c + * BY : Erich Chen (erich@tekram.com.tw) + * Description: Device Driver for Tekram DC395U/UW/F,DC315/U + * PCI SCSI Bus Master Host Adapter + * (SCSI chip set used Tekram ASIC TRM-S1040) + * (C)Copyright 1995-1999 Tekram Technology Co., Ltd. + * (C)Copyright 2001-2002 Ashley R.
