Subject: [PATCH 00/25] mpt3sas: Mergering mpt2sas & mpt3sas driver code
Last time we have posted a set of patches which combine the mpt2sas
and mpt3sas driver code. and we are generating two driver modules
(i.e. two separate .ko's) from this Combined driver source.
Now we have modified above Combined driver source (i.e. single driver
source with two .ko's) to a Merged driver source (i.e. sing source with
single .ko) which supports both LSI MPT Fusion SAS 2.0 and SAS 3.0
generation HBAs.
Here I am once again posting first 18 patches of Combined driver source
along with last 7 patches which converts this Combined driver source to
Merged driver source.
Here is the change list from Combined driver src to Merged driver src
* 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 to
process only those ioctl cmds issued for the SAS2 HBAs and mpt3ctl
device to process only those ioctl cmds issued for the SAS3 HBAs.
* Added two separate ioc number indexing for SAS2 and SAS3 HBAs.
* Replaced compile time check 'MPT2SAS_SCSI' to run time check
'hba_mpi_version_belonged' wherever needed.
* Aliased this merged driver to mpt2sas using MODULE_ALIAS.so that
still user can load this merged driver with 'modprobe mpt2sas'.
* Moved global variable 'driver_name' to per adapter instance variable.
* Created two raid function templates 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.
* Updated the Makefile to built as a mpt3sas_warpdrive.o file.
* Added module parameter 'hbas_to_enumarate', which user can use this
merged driver as legacy mpt2sas driver or as a
legacy mpt3sas driver if needed.
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
* Added SCSI_MPT3SAS_MERGED config option, This Kconfig option is only
used for legacy mpt2sas/mpt3sas interoperability.
In patch 5 (ie. mpt2sas: Removed .c and .h files from mpt2sas driver)
we are just removing mpt2sas driver files. so one can just provide below
command if this patch is not reached to linux-scsi community mail list,
"git rm drivers/scsi/mpt2sas/mpt2sas_base.*
drivers/scsi/mpt2sas/mpt2sas_config.c
drivers/scsi/mpt2sas/mpt2sas_ctl.*
drivers/scsi/mpt2sas/mpt2sas_scsih.c
drivers/scsi/mpt2sas/mpt2sas_transport.c
drivers/scsi/mpt2sas/mpt2sas_debug.h"
Thanks,
