So if either one of the interrupt type sets the routing model so that TEL3=1 when CSS=0 , the FIQ bit in SCR_EL3 will be programmed to route the FIQ signal to EL3 when executing in Secure-EL1. The latter has now announced the first of their own design with Ampere Altra, an 80-core Arm Neoverse N1 server processor made for data centers. com: redhat. The AArch64 exception model is made up of a number of exception levels (EL0 - EL3), with EL0 and EL1 having a secure and a non-secure. > For this to be used you need a GICv3 host machine (a fast model would do), > though it does not rely on any host ITS bits (neither in hardware or software). -gic_it_add() should result in configuring a given interrupt to G1S instead of G0 for GICv3. 4 © 2017 Arm Limited GICv3 adds support for message based interrupts (MBI) Instead of using a dedicated signal, a peripheral writes a register in the GIC to register an interrupt Message based interrupts -new in GICv3 GIC ARM IRQ FIQ Peripheral Interrupt Interconnect message Why?

ARM上又搞出来一个Affinity Routing的概念,GICv3使用Affinity Routing来标志一个特定的PE或者是一组特定的PE, 有点类似于x86上的APICID/X2APIC ID机制。ARM使用4个8bit的域来表示affinity,格式如:. Arm CoreLink Generic Interrupt Controller v3 and v4: Virtualization Background An interrupt is a signal to the processor that an event has occurred which needs to be dealt with. This document is only available in a PDF version. The created VGIC will act as the VM interrupt controller, requiring emulated user-space devices to inject interrupts to the VGIC instead of directly to CPUs.
