[PATCH v4 8/9] perf c2c: Support AUX trace

From: Leo Yan
Date: Fri Nov 06 2020 - 04:50:09 EST


This patch adds the AUX callbacks in session structure, so support
AUX trace for "perf c2c" tool; make itrace memory event as default for
"perf c2c", this tells the AUX trace decoder to synthesize samples and
can be used for statistics.
