  • 84652e834   PM / MIPS: Convert i8259.c to using syscore_ops ... Browse Code »

    The code in arch/mips/kernel/i8259.c still hasn't been converted to
    using struct syscore_ops instead of a sysdev for resume and shutdown.
    As a result, this code doesn't build any more after suspend, resume
    and shutdown callbacks have been removed from struct sysdev_class.
    Fix this problem by converting i8259.c to using syscore_ops.

    Add missing #inclusions of to a whole bunch of files that should
    really include it. Note that this can replace #inclusions of .

    This is required for the patch to sort out irqflags handling function naming to
    compile on MIPS.

    The problem is that these files require access to things like setup_irq() -
    which isn't available by #including

  • 639702bd7   [MIPS] Register PCI host bridge resource earlier ... Browse Code »

    PCI based SNI RM machines have their EISA bus behind an Intel PCI/EISA
    bridge. So the PCI IO range must start at 0x0000. Changing that will
    break the PCI bus, because i8259.c already has registered it's IO
    addresses before the PCI bus gets initialized. Below is a patch,
    which will register the PCI host bridge resources inside
    register_pci_controller(). It also changes i8259.c to use insert_region(),
    because request_resource() will fail, if the IO space of the PIT hanging
    of the PCI host bridge (maybe passing the resource parent to
    init_i8259_irqs() is a cleaner fix for that).

  • 1603b5aca   [MIPS] IRQ cleanups ... Browse Code »

    This is a big irq cleanup patch.

    * Use set_irq_chip() to register irq_chip.
    * Initialize .mask, .unmask, .mask_ack field. Functions for these
    method are already exist in most case.
    * Do not initialize .startup, .shutdown, .enable, .disable fields if
    default routines provided by irq_chip_set_defaults() were suitable.
    * Remove redundant irq_desc initializations.
    * Remove unnecessary local_irq_save/local_irq_restore, spin_lock.

    With this cleanup, it would be easy to switch to slightly lightwait
    irq flow handlers (handle_level_irq(), etc.) instead of __do_IRQ().

    Though whole this patch is quite large, changes in each irq_chip are
    not quite simple. Please review and test on your platform. Thanks.

  • d1bef4ed5   [PATCH] genirq: rename desc->handler to desc->chip ... Browse Code »

    This patch-queue improves the generic IRQ layer to be truly generic, by adding
    various abstractions and features to it, without impacting existing
    functionality.

    While the queue can be best described as "fix and improve everything in the
    generic IRQ layer that we could think of", and thus it consists of many
    smaller features and lots of cleanups, the one feature that stands out most is
    the new 'irq chip' abstraction.

    The irq-chip abstraction is about describing and coding and IRQ controller
    driver by mapping its raw hardware capabilities [and quirks, if needed] in a
    straightforward way, without having to think about "IRQ flow"
    (level/edge/etc.) type of details.

    This stands in contrast with the current 'irq-type' model of genirq
    architectures, which 'mixes' raw hardware capabilities with 'flow' details.
    The patchset supports both types of irq controller designs at once, and
    converts i386 and x86_64 to the new irq-chip design.

    As a bonus side-effect of the irq-chip approach, chained interrupt controllers
    (master/slave PIC constructs, etc.) are now supported by design as well.

    The end result of this patchset intends to be simpler architecture-level code
    and more consolidation between architectures.

    We reused many bits of code and many concepts from Russell King's ARM IRQ
    layer, the merging of which was one of the motivations for this patchset.

    This patch:

    rename desc->handler to desc->chip.

    Originally i did not want to do this, because it's a big patch. But having
    both "desc->handler", "desc->handle_irq" and "action->handler" caused a
    large degree of confusion and made the code appear alot less clean than it
    truly is.

    I have also attempted a dual approach as well by introducing a
    desc->chip alias - but that just wasnt robust enough and broke
    frequently.

    So lets get over with this quickly. The conversion was done automatically
    via scripts and converts all the code in the kernel.

    This renaming patch is the first one amongst the patches, so that the
    remaining patches can stay flexible and can be merged and split up
    without having some big monolithic patch act as a merge barrier.

    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!
