  • 3b198ddd5   irqchip/bcm7038-l1: Implement irq_cpu_offline() callback ... Browse Code »

    commit 34c535793bcbf9263cf22f8a52101f796cdfab8e upstream.

    We did not implement an irq_cpu_offline callback for our irqchip, yet we
    support setting a given IRQ's affinity. This resulted in interrupts
    whose affinity mask included CPUs being taken offline not to work
    correctly once the CPU had been put offline.

    Fixes: 5f7f0317ed28 ("IRQCHIP: Add new driver for BCM7038-style level 1 interrupt controllers")

  • 97139d4a6   treewide: remove redundant #include <linux/kconfig.h> ... Browse Code »

    Kernel source files need not include explicitly
    because the top Makefile forces to include it with:

    -include $(srctree)/include/linux/kconfig.h

    This commit removes explicit includes except the following:

    * arch/s390/include/asm/facilities_src.h
    * tools/testing/radix-tree/linux/kernel.h

    These two are used for host programs.

  • bd0b9ac40   genirq: Remove irq argument from irq flow handlers ... Browse Code »

    Most interrupt flow handlers do not use the irq argument. Those few
    which use it can retrieve the irq number from the irq descriptor.

    Remove the argument.

    Search and replace was done with coccinelle and some extra helper
    scripts around it. Thanks to Julia for her help!

    Chained irq handlers usually set up handler data as well. We now have
    a function to set both under irq_desc->lock. Replace the two calls
    with one.

    Search and conversion was done with coccinelle:

  • 41a83e06e   irqchip: Prepare for local stub header removal ... Browse Code »

    The IRQCHIP_DECLARE macro moved to to 'include/linux/irqchip.h', so
    the local irqchip.h became an empty shell, which solely includes
    include/linux/irqchip.h

    Include the global header in all irqchip drivers instead of the local
    header, so we can remove it.

  • 5f7f0317e   IRQCHIP: Add new driver for BCM7038-style level 1 interrupt controllers ... Browse Code »

    This is the main peripheral IRQ controller on the BCM7xxx MIPS chips;
    it has the following characteristics:

    - 64 to 160+ level IRQs
    - Atomic set/clear registers
    - Reasonably predictable register layout (N status words, then N
    mask status words, then N mask set words, then N mask clear words)
    - SMP affinity supported on most systems
    - Typically connected to MIPS IRQ 2,3,2,3 on CPUs 0,1,2,3

    This driver registers one IRQ domain and one IRQ chip to cover all
    instances of the block. Up to 4 instances of the block may appear, as
    it supports 4-way IRQ affinity on BCM7435.

    The same block exists on the ARM BCM7xxx chips, but typically the ARM GIC
    is used instead. So this driver is primarily intended for MIPS STB chips.
