perf cs-etm: Support for ARM A32/T32 instruction sets in CoreSight trace
This patch adds support for generating instruction samples from trace of
AArch32 programs using the A32 and T32 instruction sets.
T32 has variable 2 or 4 byte instruction size, so the conversion between
addresses and instruction counts requires extra information from the
trace decoder, requiring version 0.10.0 of OpenCSD. A check for the
OpenCSD library version has been added to the feature check for OpenCSD.
