This command is used to query information about the interrupts.

## Syntax<a name="section1795712553416"></a>

hwi

## Parameters<a name="section92544592410"></a>

None

## Usage<a name="section104151141252"></a>

-   Run  **hwi**  to display the current interrupt ID, count of interrupts, and registered interrupt name.
-   If  **LOSCFG\_CPUP\_INCLUDE\_IRQ**  is enabled, the processing time \(cycles\), CPU usage, and interrupt type of each interrupt are displayed.

## Example<a name="section11545171957"></a>

Enter  **hwi**.

## Output<a name="section075617368542"></a>

1.  Interrupt information \(**LOSCFG\_CPUP\_INCLUDE\_IRQ**  disabled\)
