From 86297c41a26f18d924e64fc93321c59cbc4c48dd Mon Sep 17 00:00:00 2001 From: Thomas Bushnell Date: Mon, 26 Apr 1999 05:58:44 +0000 Subject: 1998-11-30 OKUJI Yoshinori Clean up linux emulation code to make it architecture-independent as much as possible. * linux: Renamed from linuxdev. * Makefile.in (objfiles): Add linux.o instead of linuxdev.o. (MAKE): New variable. Used for the linux.o target. * configure.in: Add AC_CHECK_TOOL(MAKE, make). * i386/i386/spl.h: Include , for compatibility with OSF Mach 3.0. Suggested by Elgin Lee . * linux/src: Renamed from linux/linux. * linux/dev: Renamed from linux/mach. * linux/Drivers.in (AC_INIT): Use dev/include/linux/autoconf.h, instead of mach/include/linux/autoconf.h. * Makefile.in (all): Target ../linux.o instead of ../linuxdev.o. * linux/dev/drivers/block/genhd.c: Include instead of . * linux/dev/drivers/net/auto_irq.c: Remove unneeded header files, and . * linux/dev/init/main.c: Many i386-dependent codes moved to ... * linux/dev/arch/i386/irq.c: ... here. * linux/dev/arch/i386/setup.c: New file. * linux/dev/arch/i386/linux_emul.h: Likewise. * linux/dev/arch/i386/glue/timer.c: Merged into sched.c. * linux/dev/arch/i386/glue/sched.c: Include instead of , and moved to ... * linux/dev/kernel/sched.c: ... here. * linux/dev/arch/i386/glue/block.c: Include and , instead of i386-dependent header files, and moved to ... * linux/dev/glue/blocl.c: ... here. * linux/dev/arch/i386/glue/net.c: Include and , instead of i386-dependent header files, and moved to ... * linux/dev/glue/net.c: ... here. * linux/dev/arch/i386/glue/misc.c: Remove `x86' and moved to ... * linux/dev/glue/misc.c: ... here. * linux/dev/arch/i386/glue/kmem.c: Moved to ... * linux/dev/glue/kmem.c: ... here. --- linux/src/drivers/scsi/aic7xxx/scsi_message.h | 41 ++++++++ linux/src/drivers/scsi/aic7xxx/sequencer.h | 135 ++++++++++++++++++++++++++ 2 files changed, 176 insertions(+) create mode 100644 linux/src/drivers/scsi/aic7xxx/scsi_message.h create mode 100644 linux/src/drivers/scsi/aic7xxx/sequencer.h (limited to 'linux/src/drivers/scsi/aic7xxx') diff --git a/linux/src/drivers/scsi/aic7xxx/scsi_message.h b/linux/src/drivers/scsi/aic7xxx/scsi_message.h new file mode 100644 index 0000000..16c4013 --- /dev/null +++ b/linux/src/drivers/scsi/aic7xxx/scsi_message.h @@ -0,0 +1,41 @@ +/* Messages (1 byte) */ /* I/T (M)andatory or (O)ptional */ +#define MSG_CMDCOMPLETE 0x00 /* M/M */ +#define MSG_EXTENDED 0x01 /* O/O */ +#define MSG_SAVEDATAPOINTER 0x02 /* O/O */ +#define MSG_RESTOREPOINTERS 0x03 /* O/O */ +#define MSG_DISCONNECT 0x04 /* O/O */ +#define MSG_INITIATOR_DET_ERR 0x05 /* M/M */ +#define MSG_ABORT 0x06 /* O/M */ +#define MSG_MESSAGE_REJECT 0x07 /* M/M */ +#define MSG_NOOP 0x08 /* M/M */ +#define MSG_PARITY_ERROR 0x09 /* M/M */ +#define MSG_LINK_CMD_COMPLETE 0x0a /* O/O */ +#define MSG_LINK_CMD_COMPLETEF 0x0b /* O/O */ +#define MSG_BUS_DEV_RESET 0x0c /* O/M */ +#define MSG_ABORT_TAG 0x0d /* O/O */ +#define MSG_CLEAR_QUEUE 0x0e /* O/O */ +#define MSG_INIT_RECOVERY 0x0f /* O/O */ +#define MSG_REL_RECOVERY 0x10 /* O/O */ +#define MSG_TERM_IO_PROC 0x11 /* O/O */ + +/* Messages (2 byte) */ +#define MSG_SIMPLE_Q_TAG 0x20 /* O/O */ +#define MSG_HEAD_OF_Q_TAG 0x21 /* O/O */ +#define MSG_ORDERED_Q_TAG 0x22 /* O/O */ +#define MSG_IGN_WIDE_RESIDUE 0x23 /* O/O */ + +/* Identify message */ /* M/M */ +#define MSG_IDENTIFYFLAG 0x80 +#define MSG_IDENTIFY_DISCFLAG 0x40 +#define MSG_IDENTIFY(lun, disc) (((disc) ? 0xc0 : MSG_IDENTIFYFLAG) | (lun)) +#define MSG_ISIDENTIFY(m) ((m) & MSG_IDENTIFYFLAG) + +/* Extended messages (opcode and length) */ +#define MSG_EXT_SDTR 0x01 +#define MSG_EXT_SDTR_LEN 0x03 + +#define MSG_EXT_WDTR 0x03 +#define MSG_EXT_WDTR_LEN 0x02 +#define MSG_EXT_WDTR_BUS_8_BIT 0x00 +#define MSG_EXT_WDTR_BUS_16_BIT 0x01 +#define MSG_EXT_WDTR_BUS_32_BIT 0x02 diff --git a/linux/src/drivers/scsi/aic7xxx/sequencer.h b/linux/src/drivers/scsi/aic7xxx/sequencer.h new file mode 100644 index 0000000..7c0121e --- /dev/null +++ b/linux/src/drivers/scsi/aic7xxx/sequencer.h @@ -0,0 +1,135 @@ +/* + * Instruction formats for the sequencer program downloaded to + * Aic7xxx SCSI host adapters + * + * Copyright (c) 1997, 1998 Justin T.
