From af0094115b080b41eb5a3567c177ce960a07dea4 Mon Sep 17 00:00:00 2001 From: Sreekanth Reddy Date: Wed, 11 Nov 2015 17:30:23 +0530 Subject: mpt2sas, mpt3sas: Remove SCSI_MPTXSAS_LOGGING entry from Kconfig 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 attribute is located in: /sys/class/scsi_host/host#/BMR_status When reading this adapter attribute, the driver will output the state of GPIO[24]. It returns "0" if BMR is healthy and "1" for failure. If it returns an empty string then it means that there was an error while obtaining the BMR status. Check dmesg for what error has occurred. This sysfs shost attribute is mainly for WarpDrive controllers. This commit is a port of 6c265660c262 ("mpt2sas: Provide sysfs attribute to report Backup Rail Monitor Status").

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.
