  • 99a700bcc   [SCSI] mv_sas: OCZ RevoDrive3 & zDrive R4 support ... Browse Code »

    In the OCZ RevoDrive3/zDrive R4 series, the "OCZ SuperScale Storage
    Controller" with "Virtualized Controller Architecture 2.0" really seems
    to be a Marvell 88SE9485 part, with OCZ firmware/BIOS.

    Developed and tested on OCZ RevoDrive3 120GB [PCI 1b85:1021]

    Should work on:
    - OCZ RevoDrive3 (2x SandForce 2281)
    - OCZ RevoDrive3 X2 (4x SandForce 2281)
    - OCZ zDrive R4 CM84 (4x SandForce 2281)
    - OCZ zDrive R4 CM88 (8x SandForce 2281)
    - OCZ zDrive R4 RM84 (4x SandForce 2582)
    - OCZ zDrive R4 RM88 (8x SandForce 2582)

    All of this because a friend recently bought a OCZ RevoDrive3 and was
    bitten by the lack of Linux support.

    Notes from testing:
    -------------------
    - SMART works.
    - VPD Device Identification is "OCZ-REVODRIVE3"
    - Thin provisioning/TRIM seems to be implemented as WRITE SAME UNMAP,
    with deterministic (non-zero) read after TRIM, but I'm not sure if it
    works 100% in my testing.
    - Some of the tuning in the firmware seems to ensure much better
    performance when in a RAID0 setup than using the two devices
    seperately.

    I have not tested booting from the SSD, because all of this was
    developed and tested remotely from the actual hardware.

  • df64d3caa   [SCSI] Unify SAM_ and SAM_STAT_ macros ... Browse Code »

    We have two separate definitions for identical constants with nearly the
    same name. One comes from the generic headers in scsi.h; the other is
    an enum in libsas.h ... it's causing confusion about which one is
    correct (fortunately they both are).

    Fix this by eliminating the libsas.h duplicate

  • 9dc9fd948   [SCSI] mvsas: fix hot plug handling and IO issues ... Browse Code »

    This patch adds a bunch of fixes

    1. Reduce sg table size to 64 (SG_MX) instead of default SG_ALL
    2. clear task lists on phy down events
    3. release all tasks on port deformation
    4. release current task for device gone notification
    5. Add sata abort handing
    6. Add 10ms delay to each port reset (currently done serially and with
    interrupts disabled)

    [jejb: whitespace fixes and clean ups plus added description
    added dummy 94xx_clear_srs_irq function just to prevent the
    mismatch in the mvs_dispatch structure killing 94xx cards]

  • 5a0e3ad6a   include cleanup: Update gfp.h and slab.h includes to prepare for breaking implic… ... Browse Code »

    …it slab.h inclusion from percpu.h

    percpu.h is included by sched.h and module.h and thus ends up being
    included when building most .c files. percpu.h includes slab.h which
    in turn includes gfp.h making everything defined by the two files
    universally available and complicating inclusion dependencies.

    percpu.h -> slab.h dependency is about to be removed. Prepare for
    this change by updating users of gfp and slab facilities include those
    headers directly instead of assuming availability. As this conversion
    needs to touch large number of source files, the following script is
    used as the basis of conversion.

    http://userweb.kernel.org/~tj/misc/slabh-sweep.py

    The script does the followings.

    * Scan files for gfp and slab usages and update includes such that
    only the necessary includes are there. ie. if only gfp is used,
    gfp.h, if slab is used, slab.h.

    * When the script inserts a new include, it looks at the include
    blocks and try to put the new include such that its order conforms
    to its surrounding. It's put in the include block which contains
    core kernel includes, in the same order that the rest are ordered -
    alphabetical, Christmas tree, rev-Xmas-tree or at the end if there
    doesn't seem to be any matching order.

    * If the script can't find a place to put a new include (mostly
    because the file doesn't have fitting include block), it prints out
    an error message indicating which .h file needs to be added to the
    file.

    The conversion was done in the following steps.

    1. The initial automatic conversion of all .c files updated slightly
    over 4000 files, deleting around 700 includes and adding ~480 gfp.h
    and ~3000 slab.h inclusions. The script emitted errors for ~400
    files.

    2. Each error was manually checked. Some didn't need the inclusion,
    some needed manual addition while adding it to implementation .h or
    embedding .c file was more appropriate for others. This step added
    inclusions to around 150 files.

    3. The script was run again and the output was compared to the edits
    from #2 to make sure no file was left behind.

    4. Several build tests were done and a couple of problems were fixed.
    e.g. lib/decompress_*.c used malloc/free() wrappers around slab
    APIs requiring slab.h to be added manually.

    5. The script was run on all .h files but without automatically
    editing them as sprinkling gfp.h and slab.h inclusions around .h
    files could easily lead to inclusion dependency hell. Most gfp.h
    inclusion directives were ignored as stuff from gfp.h was usually
    wildly available and often used in preprocessor macros. Each
    slab.h inclusion directive was examined and added manually as
    necessary.

    6. percpu.h was updated not to include slab.h.

    7. Build test were done on the following configurations and failures
    were fixed. CONFIG_GCOV_KERNEL was turned off for all tests (as my
    distributed build env didn't work with gcov compiles) and a few
    more options had to be turned off depending on archs to make things
    build (like ipr on powerpc/64 which failed due to missing writeq).

    * x86 and x86_64 UP and SMP allmodconfig and a custom test config.
    * powerpc and powerpc64 SMP allmodconfig
    * sparc and sparc64 SMP allmodconfig
    * ia64 SMP allmodconfig
    * s390 SMP allmodconfig
    * alpha SMP allmodconfig
    * um on x86_64 SMP allmodconfig

    8. percpu.h modifications were reverted so that it could be applied as
    a separate patch and serve as bisection point.

    Given the fact that I had only a couple of failures from tests on step
    6, I'm fairly confident about the coverage of this conversion patch.
    If there is a breakage, it's likely to be something in one of the arch
    headers which should be easily discoverable easily on most builds of
    the specific arch.
