| 38 | * hardware architecture. It makes two things: |
|---|
| 39 | * - First, it access the local ICU controller to get pending interrupts for the |
|---|
| 40 | * calling core, and execute the registered ISR. It handles up to three pending |
|---|
| 41 | * interrupt at each call (one HWI, one WTI, and one PTI). |
|---|
| 42 | * - Second, it check the pending signals for the interrupted thread, and call |
|---|
| 43 | * the registered signal handlers. |
