From 9e87545f06930c1d294423a8091d1077e7444a47 Mon Sep 17 00:00:00 2001 From: Markus Lidel Date: Thu, 23 Jun 2005 22:02:21 -0700 Subject: [PATCH] I2O: second code cleanup of sparse warnings and unneeded syncronization Changes: - Added header "core.h" for i2o_core.ko internal definitions - More sparse fixes - Changed display of TID's in sysfs attributes from XXX to 0xXXX - Use the right functions for accessing I/O and normal memory - Removed error handling of SCSI device errors and let the SCSI layer take care of it - Added new device / removed device handling to SCSI-OSM - Make status access volatile - Cleaned up activation of I2O controller - Removed unnecessary wmb() and rmb() calls - Use own struct i2o_io for I/O memory instead of struct i2o_dma Signed-off-by: Markus Lidel Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds --- drivers/message/i2o/core.h | 55 ++++++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 55 insertions(+) create mode 100644 drivers/message/i2o/core.h (limited to 'drivers/message/i2o/core.h') diff --git a/drivers/message/i2o/core.h b/drivers/message/i2o/core.h new file mode 100644 index 000000000000..49851cccc48d --- /dev/null +++ b/drivers/message/i2o/core.h @@ -0,0 +1,55 @@ +/* + * I2O core internal declarations + * + * Copyright (C) 2005 Markus Lidel + * + * This program is free software; you can redistribute it and/or modify it + * under the terms of the GNU General Public License as published by the + * Free Software Foundation; either version 2 of the License, or (at your + * option) any later version. + * + * Fixes/additions: + * Markus Lidel + * initial version. + */ + +/* Exec-OSM */ +extern struct bus_type i2o_bus_type; + +extern struct i2o_driver i2o_exec_driver; +extern int i2o_exec_lct_get(struct i2o_controller *); + +extern int __init i2o_exec_init(void); +extern void __exit i2o_exec_exit(void); + +/* driver */ +extern int i2o_driver_dispatch(struct i2o_controller *, u32); + +extern int __init i2o_driver_init(void); +extern void __exit i2o_driver_exit(void); + +/* PCI */ +extern int __init i2o_pci_init(void); +extern void __exit i2o_pci_exit(void); + +/* device */ +extern void i2o_device_remove(struct i2o_device *); +extern int i2o_device_parse_lct(struct i2o_controller *); + +extern int i2o_device_init(void); +extern void i2o_device_exit(void); + +/* IOP */ +extern struct i2o_controller *i2o_iop_alloc(void); +extern void i2o_iop_free(struct i2o_controller *); + +extern int i2o_iop_add(struct i2o_controller *); +extern void i2o_iop_remove(struct i2o_controller *); + +/* control registers relative to c->base */ +#define I2O_IRQ_STATUS 0x30 +#define I2O_IRQ_MASK 0x34 +#define I2O_IN_PORT 0x40 +#define I2O_OUT_PORT 0x44 + +#define I2O_IRQ_OUTBOUND_POST 0x00000008 -- cgit v1.2.3
