Arm 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? Can reduce the number of wires needed and ease routing. • Arm® GICv3 and GICv4 Software Overview (DAI 0492). 1 1134 FADT changes for PSCI Support on ARM platforms Table 5-34, 5-36, New table 5-37.

The Generic Interrupt Controller is a standardized component of modern ARM boards, and it provides a solid interrupt handling scheme for embedded systems. With a supported Xen version, the standard compilation instructions work fine. With a GICv3 the "virt" board now supports TCG (emulated CPU) configurations with more than 8 vCPUs. The specific use case for this feature is GICv3 ARM systems that are not able to disable DMA access to LPI tables, meaning we have to reserve them and make the next kernel reuse the existing tables rather than allocating them from scratch. This allows the kernel designed to run at EL1 * to transparently mess with the EL0 bits via CNTKCTL_EL1 access in * EL2. The webinar will start with an introduction to the GIC followed by an overview of the recently released GICv3, and explain the key changes from GICv2 to GICv3 including message-based interrupts, affinity based routing, LPIs and ITSs. The Firmware CONfiguration Framework (FCONF) is an abstraction layer for platform specific data, allowing a “property” to be queried and a value retrieved without the requesting entity knowing what backing store is being used to hold the data.
