  • db5ed4dfd   scsi: drop reason argument from ->change_queue_depth ... Browse Code »

    Drop the now unused reason argument from the ->change_queue_depth method.
    Also add a return value to scsi_adjust_queue_depth, and rename it to
    scsi_change_queue_depth now that it can be used as the default
    ->change_queue_depth implementation.

  • c8b09f6fb   scsi: don't set tagging state from scsi_adjust_queue_depth ... Browse Code »

    Remove the tagged argument from scsi_adjust_queue_depth, and just let it
    handle the queue depth. For most drivers those two are fairly separate,
    given that most modern drivers don't care about the SCSI "tagged" status
    of a command at all, and many old drivers allow queuing of multiple
    untagged commands in the driver.

    Instead we start out with the ->simple_tags flag set before calling
    ->slave_configure, which is how all drivers actually looking at
    ->simple_tags except for one worke anyway. The one other case looks
    broken, but I've kept the behavior as-is for now.

    Except for that we only change ->simple_tags from the ->change_queue_type,
    and when rejecting a tag message in a single driver, so keeping this
    churn out of scsi_adjust_queue_depth is a clear win.

    Now that the usage of scsi_adjust_queue_depth is more obvious we can
    also remove all the trivial instances in ->slave_alloc or ->slave_configure
    that just set it to the cmd_per_lun default.

  • 2ecb204d0   scsi: always assign block layer tags if enabled ... Browse Code »

    Allow a driver to ask for block layer tags by setting .use_blk_tags in the
    host template, in which case it will always see a valid value in
    request->tag, similar to the behavior when using blk-mq. This means even
    SCSI "untagged" commands will now have a tag, which is especially useful
    when using a host-wide tag map.

  • a88dc06cd   scsi: delete the MCA specific drivers and driver code ... Browse Code »

    The support for CONFIG_MCA is being removed, since the 20
    year old hardware simply isn't capable of meeting today's
    software demands on CPU and memory resources.

    This commit removes the MCA specific SCSI drivers, and the
    MCA specific portions of code in dual role ISA/MCA drivers.
    Also, the MCA specific SCSI documentation is removed.

  • 395cf9691   doc: fix broken references ... Browse Code »

    There are numerous broken references to Documentation files (in other
    Documentation files, in comments, etc.). These broken references are
    caused by typo's in the references, and by renames or removals of the
    Documentation files. Some broken references are simply odd.

    Fix these broken references, sometimes by dropping the irrelevant text
    they were part of.

    this patch adds recommendations for LLDs to set resid

    has been returned by a device.

  • 0ea6e6112   Documentation: update broken web addresses. ... Browse Code »

    Below you will find an updated version from the original series bunching all patches into one big patch
    updating broken web addresses that are located in Documentation/*
    Some of the addresses date as far far back as 1995 etc... so searching became a bit difficult,
    the best way to deal with these is to use web.archive.org to locate these addresses that are outdated.
    Now there are also some addresses pointing to .spec files some are located, but some(after searching
    on the companies site)where still no where to be found. In this case I just changed the address
    to the company site this way the users can contact the company and they can locate them for the users.

  • 9e4f5e296   [SCSI] FC Pass Thru support ... Browse Code »

    Attached is the ELS/CT pass-thru patch for the FC Transport. The patch
    creates a generic framework that lays on top of bsg and the SGIO v4 ioctl
    in order to pass transaction requests to LLDD's.

    The interface supports the following operations:
    On an fc_host basis:
    Request login to the specified N_Port_ID, creating an fc_rport.
    Request logout of the specified N_Port_ID, deleting an fc_rport
    Send ELS request to specified N_Port_ID w/o requiring a login, and
    wait for ELS response.
    Send CT request to specified N_Port_ID and wait for CT response.
    Login is required, but LLDD is allowed to manage login and decide
    whether it stays in place after the request is satisfied.
    Vendor-Unique request. Allows a LLDD-specific request to be passed
    to the LLDD, and the passing of a response back to the application.
    On an fc_rport basis:
    Send ELS request to nport and wait for ELS response.
    Send CT request to nport and wait for CT response.

    The patch also exports several headers from include/scsi such that
    they can be available to user-space applications:
    include/scsi/scsi.h
    include/scsi/scsi_netlink.h
    include/scsi/scsi_netlink_fc.h
    include/scsi/scsi_bsg_fc.h

    For further information, refer to the last RFC:
    http://marc.info/?l=linux-scsi&m=123436574018579&w=2

    Note: Documentation is still spotty and will be added later.

  • 9227c33de   [PATCH] move ->eh_strategy_handler to the transport class ... Browse Code »

    Overriding the whole EH code is a per-transport, not per-host thing.
    Move ->eh_strategy_handler to the transport class, same as
    ->eh_timed_out.

    Downside is that scsi_host_alloc can't check for the total lack of EH
    anymore, but the transition period from old EH where we needed it is
    long gone already.

  • 12413197e   [SCSI] remove scsi_set_device ... Browse Code »

    scsi_add_host is the proper place to set the device, but people copy
    the scsi_set_device usage from older drivers again and again.

    note that this leaves some legacy drivers like qlogicisp/qlogicfc
    without pci association in sysfs, but they're scheduled to go away soon
    anyway.

    Initial git repository build. I'm not bothering with the full history,
    even though we have it. We can create a separate "historical" git
    archive of that later if we want to, and in the meantime it's about
    3.2GB when imported into git - space that would just make the early
    git days unnecessarily complicated, when we don't have a lot of good
    infrastructure for it.

    Let it rip!
