On Keystone SOCs, DSP cores can send interrupts to ARM host using the IRQ
|
|
controller IP. It provides 28 IRQ signals to ARM. The IRQ handler running on
|
|
HOST OS can identify DSP signal source by analyzing SRCCx bits in IPCARx
|
|
registers. This is one of the component used by the IPC mechanism used on
|
|
Keystone SOCs.
