icu_device_api
v7 v8 13 13 ALMOS-MK defines three types of IRQs, that are handled by this generic ICU device: 14 14 15 * '''HWI''' : The HardWare Interrupts are generated by a local internal peripheral. They are connected to the local ICU, to be routed to a given local core.15 * '''HWI''' : The !HardWare Interrupts are generated by a local internal peripheral. They are connected to the local ICU, to be routed to a given local core. 16 16 * '''WTI''' : The Write Triggered Interrupts are actually mailboxes implemented in the local ICU. They can be used to implement software IPIs (Inter-Processor-Interrupts), or to route an IRQ generated by an external peripheral to a given local core. 17 17 * '''PTI''' : The Programmable Timer Interrupts are actually timers generating periodic interrupts controled by softare, contained in the local ICU, and routed to a given local core.
