Subject: stopping ftrace on event
Date: Wed, 6 Jul 2022 10:50:11 +0200	[thread overview]
Message-ID: <4044532.36S9Iv5CRb@desktop> (raw)

Hi all,

I'm hunting sporadic high irq-handler latencies in a pcie driver by using 
ftrace. I'm currently using trace-cmd record but get way to large files due to 
the event being so infrequent.

Is there a way to stop tracing or dump the current trace buffer when a specific 
event occurs?

Thanks for your help,
Benjamin
