Subject: [PATCH 00/25] perf intel-pt: Add support for Event Trace and TNT disable

Hi

Brief documentation is in the last patch with more technical details in
Intel SDM (https://www.intel.com/sdm) version 076.

The patches touch mostly Intel PT and auxtrace code, with a few supporting
changes to perf script.

I am not aware of any hardware that has the new capabilities yet.

Patches can also be found here:
