* [SCSI] mptsas: Adding 1078 ROC supportEric Moore2006-06-281-7/+5
| | | | | | | | | | | | | * 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.

* [SCSI] mptsas: wide port supportEric Moore2006-06-281-271/+692
| | | | | | | | | | | | | | | | | | | | | | | | | * 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 <Eric.Moore@lsil.com> Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>
* [SCSI] mptfusion: bug fix's for raid components adding/deletingMoore, Eric2006-04-251-28/+71
| | | | | | | | | | | | | | | This patch handles case where raid hidden components are not being removed when power turned off to device attached to expander, as well as the case of exposing raid components when power is turned back on to devices attached to an expander. (This is a repost of this patch, with mptsas_is_end_device declared further up in the code.) This patch contains some other miscellaneous bug fix's.

* [SCSI] mptfusion - fix panic in mptsas_slave_configureMoore, Eric2006-04-141-1/+9
| | | | | | | | | | | | | | | | Driver panic when RAID logical volume was present when driver loaded, or when a RAID logical volume was created on the fly. This issue was created in due to recent scsi_transport_sas change, when sas_read_port_mode_page was added into the mptsas drivers slave_config entry point. This new API expects that all sdev's to be assocated to an rphy, however that is not the case for logical volumes, as they are created using scsi_add_device, instead of sas_rphy_add().

* [SCSI] fusion - expander hotplug suport in mptsas moduleMoore, Eric2006-03-141-69/+285
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This adds support for hot adding and removing expanders, and its associated attached devices. When there is a change in topology, the fusion firmware sends the MPI_EVENT_SAS_DISCOVERY event to the driver. The driver will read firmware config pages to determine what changes took place, and refresh drivers view of the world stored in ioc->sas_topology. Here is the details of the action the driver does: (1) Expander Added : The mptsas_discovery_work workqueue is called. Config pages read, and ioc->sas_topology is refreshed. The sas_phy_add() is called for each phy of the expander. The expanders attached devices are added via sas_rphy_add(). Added end devices are handled within the MPT_ADD_DEVICE logic in mptsas_hotplug_work workqueue. (2) Expander Delete : The sas_rphy_delete() will be called for the top most compenent of the parent that the expander is attached to. The sas_rphy_delete call will delete all the children phys, rphys, and end devices. This is handled from mptsas_discovery_work workqueue.

* [SCSI] fusion - exposing raid components in mptsasMoore, Eric2006-03-141-26/+86
| | | | | | | | | | | | | | | | | Suppport for exposing hidden raid components for sg interface. The sdev->no_uld_attach flag will set set accordingly. The sas module supports adding/removing raid volumes using online storage management application interface. This patch rely's on patch's provided to me by Christoph Hellwig, that exports device_reprobe. I will post those patch's on behalf of Christoph.

| | | | | | | | | | | Add a flag to mark a PHY as attached to the HBA as opposed to beeing on an expander. This is needed because various features are only supported on those.

This is done because SAS supports RAID, as well as SPI, so the raid stuff should be seperate. * incorrect timeout calculation for cntdn inside WaitForDoorbellAck and WaitForDoortbellInt * add support for interpreting SAS Log Info * Increase Event Log Size from 0xA to 0x32 * Fix bug in mptsas/mptfc/mptspi - when controller has Initiator Mode Disabled, and only running in TargetMode, the mptctl would panic when loading. The fix is to return 0, instead of -ENODEV, in SCSI LLD respective probe routines * Fix bug in mptlan.c - driver will panic if there is host reset, due to dev being set to zero in mpt_lan_ioc_reset * Fix's for SPI - Echo Buffer * Several fix's in mptscsih_io_done - FCP Response info, RESIDUAL_MISMATCH, Data Underrun, etc. * Cleanup Error Handling - EH handlers, mptscsih_flush_cmds, and zeroing out ScsiLookup from mptscsih_qcmd * Cleanup asyn event handling from mptscsih -> mptscsih_event_process.
