Subject: [PATCH 01/11] perf tools script: Handle missing fields with -F +..
Date: Sun, 24 Feb 2019 07:37:12 -0800	[thread overview]
Message-ID: <20190224153722.27020-2-andi@firstfloor.org> (raw)
In-Reply-To: <20190224153722.27020-1-andi@firstfloor.org>

From: Andi Kleen <ak@linux.intel.com>

When using -F + syntax to add a field the existing defaults
are currently all marked user_set. This can cause errors when
some field is missing in the perf.data

This patch tracks the actually user set fields separately,
so that we don't error out in this case.

Before:

% perf record true
% perf script -F +metric
Samples for 'cycles:ppp' event do not have CPU attribute set. Cannot print 'cpu' field.
%

After

5 perf record true
% perf script -F +metric
            perf 28936 278636.237688:          1 cycles:ppp:  ffffffff8117da99 perf_event_exec+0x59 (/lib/modules/4.20.0-odilo/build/vmlinux)
...
