The popDebugGroup() method of the {{domxref("GPUComputePassEncoder")}} interface ends a compute pass debug group, which is begun with a {{domxref("GPUComputePassEncoder.pushDebugGroup", "pushDebugGroup()")}} call.

This could be used for telemetry, or may be utilized in {{domxref("GPUError")}} messages, browser dev tools, or other services in the future to help with debugging.

Syntax

js-nolint
popDebugGroup()

Parameters

None.

Return value

None ({{jsxref("Undefined")}}).

Validation

The following criteria must be met when calling popDebugGroup(), otherwise a {{domxref("GPUValidationError")}} is generated and the {{domxref("GPUComputePassEncoder")}} becomes invalid:

  • The compute pass encoder's debug stack is not empty (i.e., at least one compute pass debug group was previously started with {{domxref("GPUComputePassEncoder.pushDebugGroup", "pushDebugGroup()")}}).

Examples

js
// …

const passEncoder = commandEncoder.beginComputePass();

passEncoder.pushDebugGroup("my_group_marker"); // Start labeled debug group

passEncoder.setPipeline(computePipeline);
passEncoder.setBindGroup(0, bindGroup);
passEncoder.dispatchWorkgroups(Math.ceil(BUFFER_SIZE / 64));

passEncoder.popDebugGroup();

// …
