With pvSCSI it is possible for a Xen domU to issue SCSI commands to a SCSI LUN assigned to that domU. The SCSI commands are passed to the pvSCSI backend in a driver domain (usually Dom0) which is owner of the physical device. This allows e.g. to use SCSI tape drives in a Xen domU. The code is taken from the pvSCSI implementation in Xen done by Fujitsu based on Linux kernel 2.6.18. Changes from the original version are: - port to upstream kernel - put all code in just one source file - move module to appropriate location in kernel tree - adapt to Linux style guide - some minor code simplifications - replace constants with defines - remove not used defines - add support for larger SG lists by putting them in a granted page Signed-off-by: Juergen Gross <jgross@suse.com> Acked-by: Christoph Hellwig <hch@lst.de> Signed-off-by: David Vrabel <david.vrabel@citrix.com>

* 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.

The lpfc driver is forcing CONFIG_GENERIC_CSUM on which means we are unable to make the decision to enable it in the arch Kconfig. If the option exists it is always forced on. This got introduced in 3.10 via commit 6a7252fdb0c3 ([SCSI] lpfc: fix up Kconfig dependencies). I spoke to Randy about it and the original issue was with CRC_T10DIF not being defined.

| | | | | | | | | | | | | | | | | | | | | | | | scsi_wait_scan was introduced with asynchronous host scanning as a hack for distributions that weren't using proper udev based wait for root to appear in their initramfs scripts. In 2.6.30 Commit c751085943362143f84346d274e0011419c84202 Author: Rafael J. Wysocki <rjw@sisk.pl> Date: Sun Apr 12 20:06:56 2009 +0200 PM/Hibernate: Wait for SCSI devices scan to complete during resume Actually broke scsi_wait_scan because it renders scsi_complete_async_scans() a nop for modular SCSI if you include scsi_scans.h (which this module does). The lack of bug reports is sufficient proof that this module is no longer used.

They were mostly limited to 386-sx 16MHz CPU and some 486 class machines and never more than 64MB of RAM. Even the enthusiast hobbyist community seems to have dried up close to ten years ago, based on what you can find searching various websites dedicated to the relatively short lived hardware. So lets remove the support relating to CONFIG_MCA. There is no point carrying this forward, wasting cycles doing routine maintenance on it; wasting allyesconfig build time on validating it, wasting I/O on git grep'ping over it, and so on." Let's see if anybody screams. It generally has compiled, and James Bottomley pointed out that there was a MCA extension from NCR that allowed for up to 4GB of memory and PPro-class machines. So in *theory* there may be users out there. But even James (technically listed as a maintainer) doesn't actually have a system, and while Alan Cox claims to have a machine in his cellar that he offered to anybody who wants to take it off his hands, he didn't argue for keeping MCA support either. So we could bring it back. But somebody had better speak up and talk about how they have actually been using said MCA hardware with modern kernels for us to do that. And David already took the patch to delete all the networking driver code (commit a5e371f61ad3: "drivers/net: delete all code/drivers depending on CONFIG_MCA"). * 'delete-mca' of git://git.kernel.org/pub/scm/linux/kernel/git/paulg/linux: MCA: delete all remaining traces of microchannel bus support. scsi: delete the MCA specific drivers and driver code serial: delete the MCA specific 8250 support. arm: remove ability to select CONFIG_MCA
