From 1e9b51c28312f7334394aa30be56ff52c2b65b7e Mon Sep 17 00:00:00 2001 From: Markus Metzger Date: Tue, 25 Nov 2008 09:24:15 +0100 Subject: x86, bts, ftrace: a BTS ftrace plug-in prototype Impact: add new ftrace plugin A prototype for a BTS ftrace plug-in. The tracer collects branch trace in a cyclic buffer for each cpu. The tracer is not configurable and the trace for each snapshot is appended when doing cat /debug/tracing/trace. This is a proof of concept that will be extended with future patches to become a (hopefully) useful tool.
