Subject: perf cs-etm: Update decoder code for OpenCSD version 1.4
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=c6535b6ba93477c491e3816af5eed845813c6f3b;p=linux.git

perf cs-etm: Update decoder code for OpenCSD version 1.4

OpenCSD version 1.4 is released with support for FEAT_ITE.

This adds a new packet type, with associated output element ID in the
packet type enum - OCSD_GEN_TRC_ELEM_INSTRUMENTATION.

As we just ignore this packet in perf, add to the switch statement to
avoid the "enum not handled in switch error", but conditionally so as
not to break the perf build for older OpenCSD installations.
