CONFIG_RING_BUFFER_BENCHMARK: Ring buffer benchmark stress tester

General informations

The Linux kernel configuration item CONFIG_RING_BUFFER_BENCHMARK:

Help text

This option creates a test to stress the ring buffer and benchmark it. It creates its own ring buffer such that it will not interfere with any other users of the ring buffer (such as ftrace). It then creates a producer and consumer that will run for 10 seconds and sleep for 10 seconds. Each interval it will print out the number of events it recorded and give a rough estimate of how long each iteration took.

It does not disable interrupts or raise its priority, so it may be affected by processes that are running.

If unsure, say N.
