.. SPDX-License-Identifier: GPL-2.0 SIGINT BEHAVIOR =============== On the first SIGINT, RTLA exits after collecting all outstanding samples up to the point of receiving the signal. When receiving more than one SIGINT, RTLA discards any outstanding samples, and exits while displaying only samples that have already been processed. If SIGINT is received during RTLA cleanup, RTLA exits immediately via the default signal handler. Note: For the purpose of SIGINT behavior, the expiry of duration specified via the -d/--duration option is treated as equivalent to receiving a SIGINT. For example, a SIGINT received after duration expired but samples have not been processed yet will drop any outstanding samples. Also note that when using the timerlat tool in BPF mode, samples are processed in-kernel; RTLA only copies them out to display them to the user. A second SIGINT does not affect in-kernel sample aggregation.
