* mpt3sas: Single driver module which supports both SAS 2.0 & SAS 3.0 HBAsSreekanth Reddy2015-11-111-61/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* mpt2sas, mpt3sas: Remove SCSI_MPTXSAS_LOGGING entry from KconfigSreekanth Reddy2015-11-111-6/+0
| | | | | | | | | | | | | | | | | | | | | Currently there is a logging level option provided for each of our drivers in the kernel configuration utility. Users can enable this option to get more verbose information. By default it is enabled. Only when this option is enabled will the functions which display the required information get compiled in. As we are merging the both drivers we can no longer provide this configuration option. Remove the SCSI_MPTXSAS_LOGGING entry from Kconfig and unconditionally enable logging (by removing the #ifdef CONFIG_SCSI_MPT3SAS_LOGGING preprocessor check conditions) so that all functions which are defined to display more verbose information get compiled in.

* This is new scsi lld device driver from LSI supporting the SAS 2.0 standard. I have split patchs by filename. * Here is list of new 6gb host controllers: LSI SAS2004 LSI SAS2008 LSI SAS2108 LSI SAS2116 * Here are the changes in the 4th posting of this patch set: (1) fix compile errors when SCSI_MPT2SAS_LOGGING is not enabled (2) add mpt2sas to the SCSI Mid Layer Makefile (3) append mpt2sas_ to the naming of all non-static functions (4) fix oops for SMP_PASSTHRU (5) doorbell algorithm imported changes from windows driver * Here are the changes in the 3rd posting of this patch set: (1) add readl following writel from the function that disables interrupts (2) replace 0xFFFFFFFFFFFFFFFFULL with ~0ULL (3) when calling pci_enable_msix, only pass one msix entry (instead of 15). (4) remove the "current HW implementation uses..... " comment in the sources (5) merged bug fix for SIGIO/POLLIN notifcation; reported by the storlib team. * Here are the changes in the 2nd posting of this patch set: (1) use little endian types in the mpi headers (2) merged in bug fix's from inhouse drivers.
