  • 1b07193b3   platform-drivers: move probe to .devinit.text in drivers/scsi ... Browse Code »

    A pointer to a probe callback is passed to the core via
    platform_driver_register and so the function must not disappear when the
    .init sections are discarded. Otherwise (if also having HOTPLUG=y)
    unbinding and binding a device to the driver via sysfs will result in an
    oops as does a device being registered late.

    An alternative to this patch is using platform_driver_probe instead of
    platform_driver_register plus removing the pointer to the probe function
    from the struct platform_driver.

  • b99b4c67d   [SCSI] sgiwd93: Fix compilation warning ... Browse Code »

    The remove() callback in platform drivers should return int in
    accordance to the definition of the platform_driver structure.
    However, the SGI-specific WD93 SCSI controller driver defines
    the callback as a void function, which causes the following
    compilation warning:

    drivers/scsi/sgiwd93.c:314: warning: initialization from
    incompatible pointer type

    This patch fixes the warning by changing the return type of
    the remove() callback to what the core driver code requires.

    the platform modalias is prefixed with "platform:". Add MODULE_ALIAS()
    to the hotpluggable SCSI platform drivers, to re-enable auto loading.

  • 8f3334eda   [SCSI] sgiwd93: interfacing to wd33c93 ... Browse Code »

    1) sgiwd93 used to switch off asynchronous mode on the wd33c93, discarding
    any "nosync"-requests from the commandline.
    But we need to allow "nosync"-requests for selected devices, for example
    the Pioneer DVD305S.
    (For the curious: this device accepts the SDTR from wd33c93 and success-
    fully sends inquiry data in sync mode, but after the data phase in the
    inquiry command does an unexpected disconnect, seemingly sending no
    "status" or "command complete". Forcing async transfers makes it work
    together flawlessly with the wd33c93. Of course, preferable would be, to
    implement wd33c93's "resume command" stuff, but that probably will not
    come soon.)

    2) Maximize benefit from the preceding Fast SCSI patch for wd33c93 by passing
    the higher input-clock frequency explicitely. To be applied after the
    mentioned wd33c93 patch.

  • 7d12e780e   IRQ: Maintain regs pointer globally rather than passing to IRQ handlers ... Browse Code »

    Maintain a per-CPU global "struct pt_regs *" variable which can be used instead
    of passing regs around manually through all ~1800 interrupt handlers in the
    Linux kernel.

    The regs pointer is used in few places, but it potentially costs both stack
    space and code to pass it around. On the FRV arch, removing the regs parameter
    from all the genirq function results in a 20% speed up of the IRQ exit path
    (ie: from leaving timer_interrupt() to leaving do_IRQ()).

    Where appropriate, an arch may override the generic storage facility and do
    something different with the variable. On FRV, for instance, the address is
    maintained in GR28 at all times inside the kernel as part of general exception
    handling.

    Having looked over the code, it appears that the parameter may be handed down
    through up to twenty or so layers of functions. Consider a USB character
    device attached to a USB hub, attached to a USB controller that posts its
    interrupts through a cascaded auxiliary interrupt controller. A character
    device driver may want to pass regs to the sysrq handler through the input
    layer which adds another few layers of parameter passing.

    I've build this code with allyesconfig for x86_64 and i386. I've runtested the
    main part of the code on FRV and i386, though I can't test most of the drivers.
    I've also done partial conversion for powerpc and MIPS - these at least compile
    with minimal configurations.

    This will affect all archs. Mostly the changes should be relatively easy.
    Take do_IRQ(), store the regs pointer at the beginning, saving the old one:

    struct pt_regs *old_regs = set_irq_regs(regs);

    And put the old one back at the end:

    set_irq_regs(old_regs);

    Don't pass regs through to generic_handle_irq() or __do_IRQ().

    In timer_interrupt(), this sort of change will be necessary:

    - update_process_times(user_mode(regs));
    - profile_tick(CPU_PROFILING, regs);
    + update_process_times(user_mode(get_irq_regs()));
    + profile_tick(CPU_PROFILING);

    I'd like to move update_process_times()'s use of get_irq_regs() into itself,
    except that i386, alone of the archs, uses something other than user_mode().

    Some notes on the interrupt handling in the drivers:

    (*) input_dev() is now gone entirely. The regs pointer is no longer stored in
    the input_dev struct.

    (*) finish_unlinks() in drivers/usb/host/ohci-q.c needs checking. It does
    something different depending on whether it's been supplied with a regs
    pointer or not.

    (*) Various IRQ handler function pointers have been moved to type
    irq_handler_t.

  • 733482e44   [PATCH] changing CONFIG_LOCALVERSION rebuilds too much, for no good reason ... Browse Code »

    This patch removes almost all inclusions of linux/version.h. The 3
    #defines are unused in most of the touched files.

    A few drivers use the simple KERNEL_VERSION(a,b,c) macro, which is
    unfortunatly in linux/version.h.

    There are also lots of #ifdef for long obsolete kernels, this was not
    touched. In a few places, the linux/version.h include was move to where
    the LINUX_VERSION_CODE was used.

    quilt vi `find * -type f -name "*.[ch]"|xargs grep -El '(UTS_RELEASE|LINUX_VERSION_CODE|KERNEL_VERSION|linux/version.h)'|grep -Ev '(/(boot|coda|drm)/|~$)'`

    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!
