  • c7bec5aba   Various drivers' irq handlers: kill dead code, needless casts ... Browse Code »

    - Eliminate casts to/from void*

    - Eliminate checks for conditions that never occur. These typically
    fall into two classes:

    1) Checking for 'dev_id == NULL', then it is never called with
    NULL as an argument.

    2) Checking for invalid irq number, when the only caller (the
    system) guarantees the irq handler is called with the proper
    'irq' number argument.

  • 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.

  • 0ebfff149   [POWERPC] Add new interrupt mapping core and change platforms to use it ... Browse Code »

    This adds the new irq remapper core and removes the old one. Because
    there are some fundamental conflicts with the old code, like the value
    of NO_IRQ which I'm now setting to 0 (as per discussions with Linus),
    etc..., this commit also changes the relevant platform and driver code
    over to use the new remapper (so as not to cause difficulties later
    in bisecting).

    This patch removes the old pre-parsing of the open firmware interrupt
    tree along with all the bogus assumptions it made to try to renumber
    interrupts according to the platform. This is all to be handled by the
    new code now.

    For the pSeries XICS interrupt controller, a single remapper host is
    created for the whole machine regardless of how many interrupt
    presentation and source controllers are found, and it's set to match
    any device node that isn't a 8259. That works fine on pSeries and
    avoids having to deal with some of the complexities of split source
    controllers vs. presentation controllers in the pSeries device trees.

    The powerpc i8259 PIC driver now always requests the legacy interrupt
    range. It also has the feature of being able to match any device node
    (including NULL) if passed no device node as an input. That will help
    porting over platforms with broken device-trees like Pegasos who don't
    have a proper interrupt tree.
