mpt3sas: Single driver module which supports both SAS 2.0 & SAS 3.0 HBAs

2015-11-12T00:50:11+00:00

Modified the mpt3sas driver to have a single driver module which supports both SAS 2.0 & SAS 3.0 HBA devices. * Added SAS 2.0 HBA device IDs to the mpt3sas_pci_table pci table. * Created two separate SCSI host templates for SAS2 and SAS3 HBAs so that, during the driver load time driver can use corresponding host template(based the pci device ID) while registering a scsi host adapter instance for that pci device. * Registered two IOCTL devices, mpt2ctl is for SAS2 HBAs & mpt3ctl for SAS3 HBAs. Also updated the code to make sure that mpt2ctl device processes only those ioctl cmds issued for the SAS2 HBAs and mpt3ctl device processes only those ioctl cmds issued for the SAS3 HBAs. * Added separate indexing for SAS2 and SAS3 HBAs. * Replaced compile time check 'MPT2SAS_SCSI' to run time check 'hba_mpi_version_belonged' whereever needed. * Aliased this merged driver to mpt2sas using MODULE_ALIAS. * Moved global varaible 'driver_name' to per adapter instance variable. * Created two raid function template and used corresponding raid function templates based on the run time check 'hba_mpi_version_belonged'. * Moved mpt2sas_warpdrive.c file from mpt2sas to mpt3sas folder and renamed it as mpt3sas_warpdrive.c. * Also renamed the functions in mpt3sas_warpdrive.c file to follow current driver function name convention. * Updated the Makefile to build mpt3sas_warpdrive.o file for these WarpDrive-specific functions. * Also in function mpt3sas_setup_direct_io(), used sector_div() API instead of division operator (which gives compilation errors on 32 bit machines). * Removed mpt2sas files, mpt2sas directory & mpt3sas_module.c file. * Added module parameter 'hbas_to_enumerate' which permits using this merged driver as a legacy mpt2sas driver or as a legacy mpt3sas driver. Here are the available options for this module parameter: 0 - Merged driver which enumerates both SAS 2.0 & SAS 3.0 HBAs 1 - Acts as legacy mpt2sas driver, which enumerates only SAS 2.0 HBAs 2 - Acts as legacy mpt3sas driver, which enumerates only SAS 3.0 HBAs * Removed mpt2sas entries from SCSI's Kconfig and Makefile files.

scsi_dh: integrate into the core SCSI code

2015-08-28T20:14:56+00:00

Stop building scsi_dh as a separate module and integrate it fully into the core SCSI code with explicit callouts at bus scan time. For now the callouts are placed at the same point as the old bus notifiers were called, but in the future we will be able to look at ALUA INQUIRY data earlier on. Note that this also means that the device handler modules need to be loaded by the time we scan the bus. The next patches will add support for autoloading device handlers at bus scan time to make sure they are always loaded if they are enabled in the kernel config.

snic: driver for Cisco SCSI HBA

2015-06-19T23:57:51+00:00

Cisco has developed a new PCI HBA interface called sNIC, which stands for SCSI NIC. This is a new storage feature supported on specialized network adapter. The new PCI function provides a uniform host interface and abstracts backend storage.

Move code that is used both by initiator and target drivers

2015-06-01T14:32:43+00:00

Move the functions that are used by both the initiator and target subsystems into scsi_common.c/.h. This change will allow to remove the initiator SCSI header include directives from most SCSI target source files in a later patch.

scsi: Conditionally compile in constants.c

2015-01-09T14:44:31+00:00

Instead of having constants.c littered with ifdef statements we should be moving dummy functions into the header and condintionally compile in constants.c if selected. And update the Kconfig description to reflect the actual size difference.

Implement a per-cpu buffer for formatting messages to avoid line breaks up under high load. This patch implements scmd_printk() and sdev_prefix_printk() using the per-cpu buffer and makes sdev_printk() a wrapper for sdev_prefix_printk().
