From: Mathieu Poirier <mathieu.poirier@linaro.org>
This RFC is rescucitating the work submitted by Pratik Patel in 2012 [1].
This set is addressing comments gathered from the initial RFC and enhance the framework in a few areas. More specifically:
. Sysfs entries have been moved to debugfs. . The removal of the "bus" concept. . Setting the size of the ETB in accordance to HW capabilities. . Adding a "status" entry in debugfs to better debug ETM configurations. . Adding cpu affinity for ETM/PTMs. . Tying of each IP block to a specific and configurable clock. . Adjusted the ETM/PTM power up sequence. . Adding support for beagle/beagleXM and ARM's TC2 platform.
Support for other platforms will be coming shortly but we felt confident the current code base was mature enough to suscitate comments. More advanced features like CTI and STMs present in the original patchset was intentionally left out to concentrate on the foundation. They will be added at a later stage when the initial framework has been ironned-out.
Regards, Mathieu
