Subject: [PATCH v1 0/2] perf/x86: fixes and improvement for Intel Atom PEBS support
Date: Wed, 2 Dec 2015 19:28:15 +0100 [thread overview]
Message-ID: <1449080897-26149-1-git-send-email-eranian@google.com> (raw)
This short series fixes total breakage of Intel Atom PEBS support in recent kernels.
The problems were introduced with the changes in the PEBS logic to handle
deeper buffer.
The first patch fixes PEBS and LBR problems, including NULL pointers, wrong pointer
arithmetic, and wrong pebs record layout assumption.
The second patch adds an alias for cycles:pp to Intel Atom given that perf record/top
uses cycles:pp nowadays.
