Since commit d927ef5004ef ("perf cs-etm: Add exception level consistency check"), the exception that was added to Perf will be triggered unless the following bugfix from OpenCSD is present: - _Version 1.2.1_: - __Bugfix__: ETM4x / ETE - output of context elements to client can in some circumstances be delayed until after subsequent atoms have been processed leading to incorrect memory decode access via the client callbacks. Fixed to flush context elements immediately they are committed. Rather than remove the assert and silently fail, just increase the minimum version requirement to avoid hard to debug issues and regressions.
