[PATCH 0/8] coresight: etmv4: make driver usable by Perf

From: Mathieu Poirier
Date: Mon Feb 29 2016 - 13:54:48 EST


This patchset makes the ETMv4 driver usable from Perf by way of the
recently added AUX area functionality.

The first 7 patches move code around to obtain a configuration
granularity suitable for Perf. The last patch implement the AUX area
API. Most of the code is made to resemble the work that was done on
ETMv3 as much as possible.

Best regards,
Mathieu
