    Use the newly introduced pci_ioremap_bar() function in drivers/misc.
    pci_ioremap_bar() just takes a pci device and a bar number, with the goal
    of making it really hard to get wrong, while also having a central place
    to stick sanity checks.

    As there's only one work item (media_switcher) to handle and it's effectively
    serialized with itself, I found it more convenient to use kthread instead of
    workqueue. This also allows for a working implementation of suspend/resume,
    which were totally broken in the past version.

  • 6412d9273   tifm_7xx1: Merge media insert and media remove functions ... Browse Code »

    Hardware does not say whether card was inserted or removed when reporting
    socket events. Moreover, during suspend, media can be removed or switched
    to some other card type without notification. Therefore, for each socket
    in the change set the following is performed:
    1. If there's active device in the socket it's unregistered
    2. Media detection is performed
    3. If detection recognizes supportable media, new device is registered

    This patch also alters some macros and variable names to enhance clarity.

  • 8e02f8581   tifm_sd: restructure initialization, removal and command handling ... Browse Code »

    In order to support correct suspend and resume several changes were needed:
    1. Switch from work_struct to tasklet for command handling. When device
    suspend is called workqueues are already frozen and can not be used.
    2. Separate host initialization code from driver's probe and don't rely
    on interrupts for host initialization. This, in turn, addresses two
    problems:
    a) Resume needs to re-initialize the host, but can not assume that
    device interrupts were already re-armed.
    b) Previously, probe will return successfully before really knowing
    the state of the host, as host interrupts were not armed in time.
    Now it uses polling to determine the real host state before returning.
    3. Separate termination code from driver's remove. Termination may be caused
    by resume, if media changed type or became unavailable during suspend.

  • 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.
