  • f9097dce5   pcmcia: remove irq_list parameter from pd6729 ... Browse Code »

    Remoe the irq_list parameter from pd6729, as it can and should be set
    via sysfs (and -- if available -- pcmciautils, which reads the information
    from /etc/pcmcia/config.opts )

  • a7149f9a2   pcmcia: use dev_dbg and dev_print in pd6729.c ... Browse Code »

    As suggested by Wolfram Sang , use dev_dbg(),
    and dev_{err,warn,info}() in pd6729.c, and add some "\n" suggested by
    Komuro . In the ISR, use pr_devel() and
    dev_vdbg() as they are only compiled if DEBUG (or, for dev_vdbg(),
    VERBOSE_DEBUG) are set explicitly.

    Silence following warnings:
    WARNING: drivers/pcmcia/built-in.o(.data+0x14e0): Section mismatch in reference from the variable pd6729_pci_drv to the function .devinit.text:pd6729_pci_probe()
    WARNING: drivers/pcmcia/built-in.o(.data+0x14e8): Section mismatch in reference from the variable pd6729_pci_drv to the function .devexit.text:pd6729_pci_remove()
    WARNING: drivers/pcmcia/built-in.o(.data+0x16c0): Section mismatch in reference from the variable i82092aa_pci_drv to the function .devinit.text:i82092aa_pci_probe()

    Rename the variables from *_drv to *_driver so modpost ignore the OK
    references to __devinit/__devexit functions.

  • 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.

    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!
