WebA Cortex-A9 processor enters IRQ mode in response to receiving an IRQ signal from the GIC. Before such interrupts can be used, software code has to perform a number of steps: 1.Ensure that IRQ interrupts are disabled in the A9 processor, by setting the IRQ disable bit in the CPSR to 1. 2.Conﬁgure the GIC. html knowledge testWebLKML Archive on lore.kernel.org help / color / mirror / Atom feed * [PATCH v2 1/2] irq: Add EXPORT_SYMBOL_GPL to function of irq generic-chip @ 2011-10-17 2:08 Nobuhiro Iwamatsu 2011-10-17 2:08 ` [PATCH 2/2] irq: Add function pointer table for generic-chip Nobuhiro Iwamatsu 2011-10-24 13:23 ` [PATCH v2 1/2] irq: Add EXPORT_SYMBOL_GPL to … html knowledge base templateWebHi, On Mon, Apr 25, 2016 at 02:04:52AM +0100, Andre Przywara wrote: > The Allwinner NMI irqchip driver requires GENERIC_IRQ_CHIP, but > we can't select it directly, because there is no specific Kconfig entry > for the driver.
