From d4d7d0b9545721d3cabb19d15163bbc66b797707 Mon Sep 17 00:00:00 2001 From: Chris Wilson Date: Mon, 6 Jul 2009 09:31:33 +0100 Subject: [PATCH] perf_counter: Fix the tracepoint channel to perfcounters Fix a missed rename in EVENT_PROFILE support so that it gets built and allows tracepoint tracing from the 'perf' tool. Fix a typo in the (never before built & enabled) portion in perf_counter.c as well, and update that code to the attr.config changes as well.
