  • 5eb0d6eb3   irqchip/atmel-aic: Fix potential deadlock in ->xlate() ... Browse Code »

    aic5_irq_domain_xlate() and aic_irq_domain_xlate() take the generic chip
    lock without disabling interrupts, which can lead to a deadlock if an
    interrupt occurs while the lock is held in one of these functions.

    Replace irq_gc_{lock,unlock}() calls by
    irq_gc_{lock_irqsave,unlock_irqrestore}() ones to prevent this bug from
    happening.

  • 4b5ce20b5   irqchip/atmel-aic: Remove duplicate bit operation ... Browse Code »

    AIC5 priority value is updated twice -
    in aic_common_set_priority() and when updating AT91_AIC5_SMR.
    Variable, 'smr' has updated priority value (intspec[2]) in the first step,
    so no need to update it again in the second step.

  • 5fd26a0bb   irqchip/atmel-aic: Change return type of aic_common_set_priority() ... Browse Code »

    Priority validation is not necessary because aic_common_irq_domain_xlate()
    already handles it. With this removal, return type can be changed to void.

  • dd85c7915   irqchip/atmel-aic: Handle aic_common_irq_fixup in aic_common_of_init ... Browse Code »

    AIC IRQ fixup is handled in each IRQ chip driver.
    It can be moved into aic_common_of_init() before returning the result.
    Then, aic_common_irq_fixup() can be changed to static type.

  • d32dc9aa1   irqchip/atmel-aic5: Use per chip mask caches in mask/unmask() ... Browse Code »

    When masking/unmasking interrupts, mask_cache is updated and used later
    for suspend/resume. Unfortunately, it always was the mask_cache
    associated with the first irq chip which was updated. So when performing
    resume, only irqs 0-31 could be enabled.

  • c376023b7   irqchip: Appropriate __init annotation for const data ... Browse Code »

    Init data marked const should be annotated with __initconst for
    correctness and not __initdata. And for those already __initconst,
    they should be qualified as const at the compiler level too.
    This also fixes LTO builds that otherwise fail with section mismatch
    errors.

  • 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.

  • 332fd7c4f   genirq: Generic chip: Change irq_reg_{readl,writel} arguments ... Browse Code »

    Pass in the irq_chip_generic struct so we can use different readl/writel
    settings for each irqchip driver, when appropriate. Compute
    (gc->reg_base + reg_offset) in the helper function because this is pretty
    much what all callers want to do anyway.

    Compile-tested using the following configurations:

    at91_dt_defconfig (CONFIG_ATMEL_AIC_IRQ=y)
    sama5_defconfig (CONFIG_ATMEL_AIC5_IRQ=y)
    sunxi_defconfig (CONFIG_ARCH_SUNXI=y)

    tb10x (ARC) is untested.

    Add AIC (Advanced Interrupt Controller) and AIC5 (AIC5 is an evolution of
    the AIC block) drivers.
    Put common code in irq-atmel-aic-common.c/.h so that both driver can access
    shared functions (this will ease maintenance).

    These drivers are only compatible with dt enabled board and replace the
    old implementation found in arch/arm/mach-at91/irq.c.
