| Nordic VEVIF (VPR Event Interface) - TASK TX MODE |
| |
| VEVIF is an event interface for VPR, allowing connection to the domain's DPPI |
| system. VEVIF can also generate IRQs to other CPUs. |
| |
| VEVIF provides support for inter-domain software signaling. It implements a set of tasks |
| intended for signaling within an interprocessor communication (IPC) framework. |
| When used in task tx mode, the VEVIF tasks are used to trigger IRQs on VPR core. |
| |
| Example definition: |
| |
| cpuppr_vpr: vpr@deadbeef{ |
| ... |
| cpuppr_vevif_task_tx: mailbox@0 { |
| compatible = "nordic,nrf-vevif-task-tx"; |
| reg = <0x0 0x1000>; |
| #mbox-cells = <1>; |
| nordic,tasks = <16>; |
| nordic,tasks-mask = <0xfffffff0>; |
| }; |
| }; |
| |
| compatible: "nordic,nrf-vevif-task-tx" |
