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 Reviewed-by: Leo Yan <leo.yan@linaro.org> Signed-off-by: James Clark <james.clark@arm.com> Acked-by: Suzuki Poulouse <suzuki.poulose@arm.com> Cc: Alexander Shishkin <alexander.shishkin@linux.intel.com> Cc: Jiri Olsa <jolsa@redhat.com> Cc: John Garry <john.garry@huawei.com> Cc: Mark Rutland <mark.rutland@arm.com> Cc: Mathieu Poirier <mathieu.poirier@linaro.org> Cc: Mike Leach <mike.leach@linaro.org> Cc: Namhyung Kim <namhyung@kernel.org> Cc: Will Deacon <will@kernel.org> Cc: coresight@lists.linaro.org Cc: linux-arm-kernel@lists.infradead.org Link: https //lore.kernel.org/r/20210806134109.1182235-8-james.clark@arm.com Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com> |
