  • ecb8a8472   pcmcia: convert some internal-only ioaddr_t to unsigned int ... Browse Code »

    Convert the io_req_t members to unsigned int, to allow use on machines with
    more than 16 bits worth of IO ports (i.e. secondary busses on ppc64, etc).

    There was only a couple of places in drivers where a change was needed. I
    left printk formats alone (there are lots of %04x-style formats in there),
    mostly to not change the format on the platforms that only have 16-bit io
    addresses, but also because the padding doesn't really add all that much value
    most of the time.

    I found only one sprintf of an address, and upsized the string accordingly (I
    doubt anyone will have anywhere near INT_MAX as irq value, but at least
    there's room for it now).

  • d3f46f39b   [SCSI] remove use_sg_chaining ... Browse Code »

    With the sg table code, every SCSI driver is now either chain capable
    or broken (or has sg_tablesize set so chaining is never activated), so
    there's no need to have a check in the host template.

    Also tidy up the code by moving the scatterlist size defines into the
    SCSI includes and permit the last entry of the scatterlist pools not
    to be a power of two.

    [SCSI] make pcmcia directory use obj-y|m instead of subdir-y|m

    Moved the scsi Makefile into conformance, but also caused the pcmcia
    subdirectory to get built in for the first time, leading to duplicate
    symbols in an allyesconfig build. Since evidently no-one relies on
    these being built in, fix this by ensuring they can only be built as
    modules.

  • cd354f1ae   [PATCH] remove many unneeded #includes of sched.h ... Browse Code »

    After Al Viro (finally) succeeded in removing the sched.h #include in module.h
    recently, it makes sense again to remove other superfluous sched.h includes.
    There are quite a lot of files which include it but don't actually need
    anything defined in there. Presumably these includes were once needed for
    macros that used to live in sched.h, but moved to other header files in the
    course of cleaning it up.

    To ease the pain, this time I did not fiddle with any header files and only
    removed #includes from .c-files, which tend to cause less trouble.

    Compile tested against 2.6.20-rc2 and 2.6.20-rc2-mm2 (with offsets) on alpha,
    arm, i386, ia64, mips, powerpc, and x86_64 with allnoconfig, defconfig,
    allmodconfig, and allyesconfig as well as a few randconfigs on x86_64 and all
    configs in arch/arm/configs on arm. I also checked that no new warnings were
    introduced by the patch (actually, some warnings are removed that were emitted
    by unnecessarily included header files).

    Setting .ConfigBase and .Present is now done at the pcmcia core.

    The driver cleanup missed a few places where the driver did set .Present
    to PRESENT_OPTION and later to the values from the CIS. Setting to
    PRESENT_OPTION now overrides the values from the CIS. So just remove
    those lines.

  • 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.

  • f8cfa618d   [PATCH] pcmcia: unify attach, EVENT_CARD_INSERTION handlers into one probe callback ... Browse Code »

    Unify the EVENT_CARD_INSERTION and "attach" callbacks to one unified
    probe() callback. As all in-kernel drivers are changed to this new
    callback, there will be no temporary backwards-compatibility. Inside a
    probe() function, each driver _must_ set struct pcmcia_device
    *p_dev->instance and instance->handle correctly.

    With these patches, the basic driver interface for 16-bit PCMCIA drivers
    now has the classic four callbacks known also from other buses:

    int (*probe) (struct pcmcia_device *dev);
    void (*remove) (struct pcmcia_device *dev);

    int (*suspend) (struct pcmcia_device *dev);
    int (*resume) (struct pcmcia_device *dev);
