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>;
