| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add a handler for the VIC that is suitable for MULTI_IRQ_HANDLER platforms. This can replace the ASM entry macros for platforms that use the VIC. v4: - rebase ontop of move __exception and friends to asm/exception.h - rework polling loop to handle as many irqs as possible in one go v3: - simplify irq handling loop as suggested by Grant - service interrupts from msb->lsb order v2: - allow the handler be used for !CONFIG_OF - use irq_domain_to_irq() Cc: Rob Herring <robherring2@gmail.com> Acked-by: Grant Likely <grant.likely@secretlab.ca> Acked-by: Linus Walleij <linus.walleij@linaro.org> Tested-by: Thomas Abraham <thomas.abraham@linaro.org> Signed-off-by: Jamie Iles <jamie@jamieiles.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This adds a device tree binding for the VIC based on the of_irq_init() support. This adds an irqdomain to the vic and always registers all vics in the static vic array rather than for pm only to keep track of the irq domain. struct irq_data::hwirq is used where appropriate rather than runtime masking. v3: - include linux/export.h for THIS_MODULE v2: - use irq_domain_simple_ops - remove stub implementation of vic_of_init for !CONFIG_OF - Make VIC select IRQ_DOMAIN Reviewed-by: Rob Herring <robherring2@gmail.com> Reviewed-by: Grant Likely <grant.likely@secretlab.ca> Tested-by: Thomas Abraham <thomas.abraham@linaro.org> Signed-off-by: Jamie Iles <jamie@jamieiles.com>

Each machine is modified to provide either omap2_intc_handle_irq(), omap3_intc_handle_irq() or gic_handle_irq().

| * ARM: Make global handler and CONFIG_MULTI_IRQ_HANDLER mutually exclusiveMarc Zyngier2011-11-15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Even when CONFIG_MULTI_IRQ_HANDLER is selected, the core code requires the arch_irq_handler_default macro to be defined as a fallback. It turns out nobody is using that particular feature as both PXA and shmobile have all their machine descriptors populated with the interrupt handler, leaving unused code (or empty macros) in their entry-macro.S file just to be able to compile entry-armv.S. Make CONFIG_MULTI_IRQ_HANDLER exclusive wrt arch_irq_handler_default, which allows to remove one test from the hot path. Also cleanup both PXA and shmobile entry-macro.S.

| * ARM: gic: allow GIC to support non-banked setupsMarc Zyngier2011-11-15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The GIC support code is heavily using the fact that hardware implementations are exposing banked registers. Unfortunately, it looks like at least one GIC implementation (EXYNOS) offers both the distributor and the CPU interfaces at different addresses, depending on the CPU. This problem is solved by allowing the distributor and CPU interface addresses to be per-cpu variables for the platforms that require it. The EXYNOS code is updated not to mess with the GIC internals while handling interrupts, and struct gic_chip_data is back to being private. The DT binding for the gic is updated to allow an optional "cpu-offset" value, which is used to compute the various base addresses. Finally, a new config option (GIC_NON_BANKED) is used to control this feature, so the overhead is only present on kernels compiled with support for EXYNOS. Tested on Origen (EXYNOS4) and Panda (OMAP4).
