==Article purpose==<br />
The purpose of this article is to<br />
* briefly introduce the '''GIC''' peripheral (generic interrupt controller) and its main features<br />
* indicate the level of security supported by this hardware block<br />
* explain how each instance can be allocated to the three runtime contexts and linked to the corresponding software components<br />
* explain, when needed, how to configure the GIC peripheral.<br />
<br />
==Peripheral overview==<br />
The '''GIC''' peripheral is the Arm<sup>&reg;</sup> Cortex<sup>&reg;</sup>-A7 interrupt controller. It is consequently not accessible from the Arm<sup>&reg;</sup> Cortex<sup>&reg;</sup>-M4 core.<br /><br />
<br />
===Features===<br />
Refer to [[STM32MP15 resources#Reference manuals|STM32MP15 reference manuals]] for the complete list of features, and to the software components, introduced below, to know which features are really implemented.<br><br />
<br />
===Security support===<br />
The GIC is a '''secure''' peripheral (under [[ETZPC_internal_peripheral|ETZPC]] control).<br />
<br />
==Peripheral usage and associated software==<br />
===Boot time===<br />
The GIC is configured by the FSBL (see [[Boot chains overview]]), mainly to define the routing of each interrupt to the secure or non-secure context at runtime: this configuration is further described in [[STM32MP15 interrupts]] article.<br />
<br />
===Runtime===<br />
====Overview====<br />
The GIC can be allocated:<br />
* to the Arm<sup>&reg;</sup> Cortex<sup>&reg;</sup>-A7 secure core to be used under OP-TEE with the GIC [[OP-TEE overview|OP-TEE]] driver (or [[TF-A overview|TF-A]] secure monitor if the OP-TEE is not present)<br />
* or to the Arm<sup>&reg;</sup> Cortex<sup>&reg;</sup>-A7 non-secure core to be used under Linux<sup>&reg;</sup> with the [[Interrupt overview|interrupts]] framework<br />

| [[OP-TEE_overview|OP-TEE GIC driver]]<br />
| [[Interrupt overview|Linux interrupt framework]]<br />
| <br />
|<br />
|-<br />
|}<br />
<br />
====Peripheral configuration====<br />
The configuration is applied by the firmware running in the context to which the peripheral is assigned. The configuration by itself can be performed via the [[STM32CubeMX]] tool for all internal peripherals. It can then be manually completed (especially for external peripherals) according to the information given in the corresponding software framework article.<br />
