  • 8a08a2ffd   parisc: Fix interrupt routing for C8000 serial ports ... Browse Code »

    commit dd5e6d6a3db09b16b7c222943977865eead88cc3 upstream.

    We can't use dev->mod_index for selecting the interrupt routing entry,
    because it's not an index into interrupt routing table. It will be even
    wrong on a machine with 2 CPUs (4 cores). But all needed information is
    contained in the PAT entries for the serial ports. mod[0] contains the
    iosapic address and mod_info has some indications for the interrupt
    input (at least it looks like it). This patch implements the searching
    for the right iosapic and uses this interrupt input information.

    The generic conversion eliminates the spurious no_ack and no_end
    routines, converts all the cascaded handlers to handle_simple_irq() and
    makes iosapic use a modified handle_percpu_irq() to become the same as
    the CPU irq's. This isn't an essential change, but it eliminates the
    mask/unmask overhead of handle_level_irq().

  • dfe075650   parisc: remove obsolete hw_interrupt_type ... Browse Code »

    The defines and typedefs (hw_interrupt_type, no_irq_type, irq_desc_t) have
    been kept around for migration reasons. After more than two years it's
    time to remove them finally.

    This patch cleans up one of the remaining users. When all such patches
    hit mainline we can remove the defines and typedefs finally.

    Impact: cleanup

    Convert the last remaining users to struct irq_chip and remove the
    define.

  • 0de26520c   cpumask: make irq_set_affinity() take a const struct cpumask ... Browse Code »

    Impact: change existing irq_chip API

    Not much point with gentle transition here: the struct irq_chip's
    setaffinity method signature needs to change.

    Fortunately, not widely used code, but hits a few architectures.

    Note: In irq_select_affinity() I save a temporary in by mangling
    irq_desc[irq].affinity directly. Ingo, does this break anything?

    Our prior mode of operation didn't allow nested interrupts
    because it makes the interrupt code much simpler. However,
    nested interrupts are better for latency.

    This code uses the EIEM register to simulate level interrupts
    and thus achieve nesting.

  • 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.

    This really only adds them for the machines I can check SMP on, which
    is CPU interrupts and IOSAPIC (so not any of the GSC based machines).

    With this patch, irqbalanced can be used to maintain irq balancing.
    Unfortunately, irqbalanced is a bit x86 centric, so it doesn't do an
    incredibly good job, but it does work.

    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!
