* hisi_sas: Add initial bare main driverJohn Garry2015-11-251-0/+1
| | | | | | | | | | | | | | | | | This patch adds the initial bare main driver for the HiSilicon SAS HBA. This only introduces the changes to build and load the main driver module. The complete driver consists of the core main module and also a module platform driver for driving the hw. The HBA is a platform device.

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.

With pvSCSI it is possible for a Xen domU to issue SCSI commands to a SCSI LUN assigned to that domU.

* scsi: async sd resumeDan Williams2014-04-101-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | async_schedule() sd resume work to allow disks and other devices to resume in parallel. This moves the entirety of scsi_device resume to an async context to ensure that scsi_device_resume() remains ordered with respect to the completion of the start/stop command. For the duration of the resume, new command submissions (that do not originate from the scsi-core) will be deferred (BLKPREP_DEFER). It adds a new ASYNC_DOMAIN_EXCLUSIVE(scsi_sd_pm_domain) as a container of these operations. Like scsi_sd_probe_domain it is flushed at sd_remove() time to ensure async ops do not continue past the end-of-life of the sdev. The implementation explicitly refrains from reusing scsi_sd_probe_domain directly for this purpose as it is flushed at the end of dpm_resume(), potentially defeating some of the benefit. Given sdevs are quiesced it is permissible for these resume operations to bleed past the async_synchronize_full() calls made by the driver core. We defer the resolution of which pm callback to call until scsi_dev_type_{suspend|resume} time and guarantee that the callback parameter is never NULL. With this in place the type of resume operation is encoded in the async function identifier. There is a concern that async resume could trigger PSU overload. In the enterprise, storage enclosures enforce staggered spin-up regardless of what the kernel does making async scanning safe by default. Outside of that context a user can disable asynchronous scanning via a kernel command line or CONFIG_SCSI_SCAN_ASYNC. Honor that setting when deciding whether to do resume asynchronously.

|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | After getting warnings in an allyesconfig build[1] from this driver, I decided to remind myself just how old it was, and whether it warranted fixing. In the Kconfig help text, I found: "This driver will eventually be phased out entirely" Going back to the history archive, I see the line was added[2] in Feb 2002, when we moved from v2.4.2.1 ---> v2.4.2.2 So, with over a decade of notification, and multiple major releases since then, I think we can justify removing this. Currently we have people wasting time building it during routine testing, and then wasting more time re-researching the known reported warnings, only to find that nobody really is willing to integrate the fixes[3] for it. A quick search didn't seem to indicate any active user base for it. If someone happens to have a quirky _old_ card that the eleven year old "new" driver doesn't work with, then it is entirely reasonable that they stick with a kernel version that predates this removal.
