[PATCH v2 0/2] Add CPU power management for CPU bound CTI devices.

by Mike Leach

Adds in power management for CPU bound CTI devices: i) CPU Hotplug - registers a new notifier for CPU start and stop events. ii) CPU idle PM event notifier to handle PM_ENTER, PM_ENTER_FAILED and PM_EXIT events. Tested with DB410c on Linux 5.7-rc3. Rebased onto coresight/next Changes since V1: (requested by Mathieu). 1) Split into separate patches for CPU pm and CPU hotplug handling. 2) Enable on hotplug has a specific function to enable the hardware, while leaving the enable reference counts unchanged.

[PATCH 86/91] perf: cs-etm: Update to build with latest opencsd version.

by Arnaldo Carvalho de Melo

From: Mike Leach <mike.leach(a)linaro.org> OpenCSD version v0.14.0 adds in a new output element. This is represented by a new value in the generic element type enum, which must be added to the handling code in perf cs-etm-decoder to prevent build errors due to build options on the perf project. This element is not currently used by the perf decoder. Perf build feature test updated to require a minimum of 0.14.0 Tested on Linux 5.7-rc3.
