Subject: [PATCH 9/9] perf python: Use attr.watermark in twatch.py
Date: Mon, 30 Jan 2012 23:24:39 -0200 [thread overview]
Message-ID: <1327973079-29426-10-git-send-email-acme@infradead.org> (raw)
In-Reply-To: <1327973079-29426-1-git-send-email-acme@infradead.org>
From: Arnaldo Carvalho de Melo <acme@redhat.com>
We want to be woken up for every PERF_RECORD_ event, attr.wakeup_events
is only for PERF_RECORD_SAMPLE, so also use attr.watermark = 1 to fix
that.
