Add perf.data trace type
Add a new trace type that parses Linux perf.data files directly, following the layout described in perf_data_format.md. New bundle: org.eclipse.tracecompass.incubator.perf.core - PerfDataReader: random-access reader for the file header (PERFILE2 / PERFILE1, little- and big-endian), attrs section (perf_event_attr + per-attr event IDs), feature sections (hostname, osrelease, arch, cpudesc, cpuid, cmdline, nr_cpus), and data-stream records (MMAP, MMAP2, COMM, FORK, EXIT, SAMPLE, SWITCH, SWITCH_CPU_WIDE, LOST, THROTTLE, UNTHROTTLE, FINISHED_ROUND, FINISHED_INIT), including the trailing sample_id block when sample_id_all is set. Piped headers are detected but their record stream is not decoded yet. - PerfDataTrace: TmfTrace subclass registered via plugin.xml, with aspects for timestamp, event type, PID, TID, CPU, IP, Address, Comm and Filename. Exposes trace metadata through ITmfPropertiesProvider. New bundle: org.eclipse.tracecompass.incubator.perf.core.tests - PerfDataTraceTest with validate/reader/event-iteration tests, driven by a bundled sample perf.data file. Register both bundles in tracetypes/pom.xml. This code was written with the assistance of claude opus 4.7 Signed-off-by: Matthew Khouzam <matthew.khouzam@ericsson.com> Change-Id: I43f44e9f1eaef3c886c36d9eb3a4565c92bc96bc
