If the magic number indicates ETE instantiate a OCSD_BUILTIN_DCD_ETE decoder instead of OCSD_BUILTIN_DCD_ETMV4I. ETE is the new trace feature for Armv9. Testing performed ================= * Old files with v0 and v1 headers for ETMv4 still open correctly * New files with new magic number open on new versions of perf * New files with new magic number fail to open on old versions of perf * Decoding with the ETE decoder results in the same output as the ETMv4 decoder as long as there are no new ETE packet types Signed-off-by: James Clark <redacted>
Changes look good to me with my limited knowledge about the decoder facing code.
