Linux软中断pending位图是一个长度为32的无符号整数数组,每个元素都代表32个软中断编号的状态。如果某个软中断的状态为1,表示该软中断已经被触发但还未被处理。
下面是一个示意图:
```
|----------------|----------------|----------------|----------------|
| Bit 31 - Bit 24 | Bit 23 - Bit 16 | Bit 15 - Bit 8 | Bit 7 - Bit 0 |
|----------------|----------------|----------------|----------------|
| SoftIRQ 0 | SoftIRQ 1 | SoftIRQ 2 | SoftIRQ 3 |
|----------------|----------------|----------------|----------------|
| SoftIRQ 4 | SoftIRQ 5 | SoftIRQ 6 | SoftIRQ 7 |
|----------------|----------------|----------------|----------------|
| SoftIRQ 8 | SoftIRQ 9 | SoftIRQ 10 | SoftIRQ 11 |
|----------------|----------------|----------------|----------------|
| SoftIRQ 12 | SoftIRQ 13 | SoftIRQ 14 | SoftIRQ 15 |
|----------------|----------------|----------------|----------------|
| SoftIRQ 16 | SoftIRQ 17 | SoftIRQ 18 | SoftIRQ 19 |
|----------------|----------------|----------------|----------------|
| SoftIRQ 20 | SoftIRQ 21 | SoftIRQ 22 | SoftIRQ 23 |
|----------------|----------------|----------------|----------------|
| SoftIRQ 24 | SoftIRQ 25 | SoftIRQ 26 | SoftIRQ 27 |
