Subject: [V5 1/4] perf: Add PERF_SAMPLE_BRANCH_COND
Date: Fri,  7 Mar 2014 14:36:22 +0530	[thread overview]
Message-ID: <1394183185-6219-2-git-send-email-khandual@linux.vnet.ibm.com> (raw)
In-Reply-To: <1394183185-6219-1-git-send-email-khandual@linux.vnet.ibm.com>

This patch introduces new branch filter PERF_SAMPLE_BRANCH_COND which
will extend the existing perf ABI. Various architectures can provide
this functionality with either with HW filtering support (if present)
or with SW filtering of captured branch instructions.
