The GIC is a centralized resource for supporting and managing interrupts in a system that includes at least one processor. GIC architecture splits logically into a Distributor block and one or more CPU Interface blocks.

Nothing in Clause 1 shall be construed as authority for you to make any representations on of the GIC in this document; complete information is available in the publication entitled ARM Generic Interrupt.

In the EB's secondary interrupt controller there are 4 GICs. If higher-priority interrupt(s) occur while the CPU is in an interrupt handler, the GIC will generate a pre-emptive IRQ and keep track of the previous 4 Mar 2015 licence granted by ARM in Clause 1a of such third party's ARM GIC Architecture Specification Licence; and c. offer to sell, sell, supply or otherwise distribute products which have either been (i) created by or for LICENSEE under the licence granted in Clause 1a; or (ii) manufactured by or for LICENSEE 14 Mar 2016 For educational purpose, this guide is not only a hands-on tutorial but it also tries to detail every steps along the way for the irq_ack)( struct irq_data ? data ) ;. 7 8. } Listing 1: irq_chip in Linux 4.4. In our case, the driver of interest is the ARM GIC driver and can be found in /drivers/irqchip/irq- gic.c. 2 15 Apr 2008 The interrupt controller architecture is described (in quite some detail) in infocenter.arm.com/help/index.jsp?topic=/com.arm.doc.ihi0048b/index.html. To prepare the secondary cores to receive IPIs, you need to: Enable the GIC Distributor (once, for the whole system); Enable the GIC CPU interface (for ARM Generic Interrupt Controller ARM SMP cores are often associated with a GIC, providing per processor interrupts (PPI), shared processor interrupts (SPI) and software generated interrupts (SGI). Primary GIC is attached directly to the CPU and typically has PPIs and SGIs. Secondary GICs are cascaded into the upward$
