### `proton.record` (triton::proton::RecordOp)

_Record a GPU hardware event_

Syntax:

```
operation ::= `proton.record` `(` operands `)` attr-dict
```

The operator records GPU events from performance counters.
Currently only cycle counter is supported.

Example:

```mlir
proton.record() {isStart = true, regionId = 4 : i32}
...
proton.record() {isStart = false, regionId = 4 : i32}
...
proton.record() {isStart = true, regionId = 1 : i32, granularity = 1 : i32}
...
proton.record() {isStart = false, regionId = 1 : i32, granularity = 1 : i32}
```
