From 547f9a218436ea35baf9a52e981753e44d9cff1f Mon Sep 17 00:00:00 2001 From: Eric Moore Date: Tue, 27 Jun 2006 14:42:12 -0600 Subject: [SCSI] mptsas: wide port support * Wide port support added - using James Bottomley's new SAS wide port API. (There is a known problem in sas transport layer reported yesterday to James. The Kobject dev.bus_ids for end devices are not unique across expanders. I have added a work around in this patch, where I asigning an unique port identifier for every port within the host - this solves the problem, but I expect a fix from James in the sas transport). * Adding target_alloc and target_destroy entry points, and moving code over from the slave entry points. * The renaming of some mptscsih_xxx functions declared in mptsas.c, to mptsas_xxx. * Target Reset moved from slave_destroy to hotplug work thread handling (with regard to device removal). Also inhibit IO to end device while device is being broken down . Talked to James Smart about this at Linux Expo (with questions of how the fc transport handles this). * Cleaning up the kzalloc's, and kfree's Signed-off-by: Eric Moore Signed-off-by: James Bottomley --- drivers/message/fusion/mptbase.h | 15 ++++++++++++--- 1 file changed, 12 insertions(+), 3 deletions(-) (limited to 'drivers/message/fusion/mptbase.h') diff --git a/drivers/message/fusion/mptbase.h b/drivers/message/fusion/mptbase.h index 4720f9ae86aa..ddef586e09e1 100644 --- a/drivers/message/fusion/mptbase.h +++ b/drivers/message/fusion/mptbase.h @@ -76,8 +76,8 @@ #define COPYRIGHT "Copyright (c) 1999-2005 " MODULEAUTHOR #endif -#define MPT_LINUX_VERSION_COMMON "3.03.10" -#define MPT_LINUX_PACKAGE_NAME "@(#)mptlinux-3.03.10" +#define MPT_LINUX_VERSION_COMMON "3.04.00" +#define MPT_LINUX_PACKAGE_NAME "@(#)mptlinux-3.04.00" #define WHAT_MAGIC_STRING "@" "(" "#" ")" #define show_mptmod_ver(s,ver) \ @@ -342,6 +342,7 @@ typedef struct _VirtTarget { u8 negoFlags; /* bit field, see above */ u8 raidVolume; /* set, if RAID Volume */ u8 type; /* byte 0 of Inquiry data */ + u8 deleted; /* target in process of being removed */ u32 num_luns; u32 luns[8]; /* Max LUNs is 256 */ } VirtTarget; @@ -633,7 +634,7 @@ typedef struct _MPT_ADAPTER int sas_index; /* index refrencing */ MPT_SAS_MGMT sas_mgmt; int num_ports; - struct work_struct mptscsih_persistTask; + struct work_struct sas_persist_task; struct work_struct fc_setup_reset_work; struct list_head fc_rports; @@ -642,6 +643,7 @@ typedef struct _MPT_ADAPTER struct work_struct fc_rescan_work; char fc_rescan_work_q_name[KOBJ_NAME_LEN]; struct workqueue_struct *fc_rescan_work_q; + u8 port_serial_number; } MPT_ADAPTER; /* @@ -893,6 +895,13 @@ typedef struct _mpt_sge { #define DBG_DUMP_REQUEST_FRAME_HDR(mfp) #endif +// debug sas wide ports +#ifdef MPT_DEBUG_SAS_WIDE +#define dsaswideprintk(x) printk x +#else +#define dsaswideprintk(x) +#endif + /*=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=*/ -- cgit v1.2.2 From 87cf89866790a373edcf88c12b64d6d38560acdd Mon Sep 17 00:00:00 2001 From: Eric Moore Date: Tue, 27 Jun 2006 16:09:26 -0600 Subject: [SCSI] mptsas: Adding 1078 ROC support * Adding 1078 ROC (Raid On Chip) Support - New host adapter * Moving all PCI Vendor/Device ids to using internal defines; a request from Christoph/James B. some time ago for when the next chip was added. * Removing SAS 1066/1066E Vendor/Device IDs, as there are no plans to manufacture that controller.

The attached patch eliminates all these ghosts by not allocating any devices for them if the SAS address is the SAS address of the parent.
