Subject: [PATCH 04/13] perf tests: Compensate lower sample freq with longer test loop
Date: Tue, 12 Nov 2013 17:46:09 -0300 [thread overview]
Message-ID: <1384289178-31374-5-git-send-email-acme@infradead.org> (raw)
In-Reply-To: <1384289178-31374-1-git-send-email-acme@infradead.org>
From: Adrian Hunter <adrian.hunter@intel.com>
Doesn't work for me:
./perf test -v 19
19: Test software clock events have valid period values :
--- start ---
mmap size 528384B
mmap size 528384B
All (0) samples have period value of 1!
---- end ----
Test software clock events have valid period values: FAILED!
Compensate the lower freq introduced in 67c1e4a53b17 with a longer loop,
